This article attempts to synthesise existing literature on the KEYWORDSDisamenity; landfill; property subject through the analysis of three case studies to enhance our values; urbanisation; waste understanding, especially the contextual conditions surrounding disposal the relationship. Applying this theoretical framework to the disposal practices occurring in three cities in Ghana, this article offers insight into the culpability of landfills in negatively impacting property values. In an illuminating analysis, we argue that most engineered landfills in the country serve as a catalyst in correcting the ills of uncontrolled urbanisation (governance, attitudinal and financial constraints, etc.). We opine that landfills’ relationship with host communities must be understood in relation to our overall underdevelopment, coupled with the increasing economic and technical challenges shaping much of the country’s history. Waste is one of the only things that unites all mankind. Everyone creates it – yet few people want to think about what happens next. The issue of municipal solid waste man- agement (MSWM), in particular, has, in recent years, stirred much academic and policy interests, not least because progressive city authorities are making concerted efforts to modify their management policies and practices (Oteng-Ababio 2011; Owusu, Oteng- Ababio, and Afutu-Kotey 2012). These attempts coincide with, ‘an era where “waste” is wit- nessing varied conceptualisation: as a billion dollar industry… ; expanding interests in and uses of alternative practices… ; large-scale development institutions’ investment in waste related infrastructure… ; and increasing sub-national transfers of municipal solid waste … ’ (Moore 2012, 780). These dynamics are not only intended to reduce the amount of waste meant for final disposal (Moore 2009, 2011) but also the over-reliance on landfills and the environmental costs associated with their management, which continue to grow at record pace (Fobil et al. 2008; Owusu, Oteng-Ababio, and Afutu-Kotey 2012; Elba- kidze et al. 2015). Damghani et al. (2008, 929) argue aptly that ‘a high quality solid waste CONTACT Martin Oteng-Ababio moababio@yahoo.com Urban Disaster Risk Reduction Programme, Department of Geography & Resource Development, University of Ghana, P.O.

OTENG-ABABIO ET AL. management [SWM] system not only enhances social, economic and environmental effi- ciency, and promotes sustainable development, but can also help resolve the dual crisis of resource shortages and environmental deterioration’ (also see Oteng-Ababio 2014). Despite the recent realisation and improvements in recycling and other disposal tech- niques (Post, Broekema, and Obirih-Opareh 2003; Oteng-Ababio 2014), landfilling remains the most widely used method of disposal globally. The trajectory of this condition (the bane of most ill-fated MSWM interventions) has by now been well mapped. Often times, and as rightly noted by Ali (2010), most studies in this arena remain over-dependent on generalisations based on theories from the North which offer no real way forward as they relate more to an ideal than anything on the ground, or portray the global North as always ‘getting it right’ (Oteng-Ababio, Melara, and Gabbay 2013). Indeed, there is a particular dissonance in regarding western versus local priorities in the sub-region, such that many scholars work to detail the myriad of ways in which African cities and/or governments tend to ‘fail’ when compared to western cities. Robinson (2006, 2) aptly suggests that ‘these concep- tual fields continue to ascribe innovation and dynamism – modernity – to cities in rich countries, while imposing a catch-up fiction of modernization on the poorest’. To her, this has led to urban theorising that is truncated by developmentalism, which has pro- duced a view of the West as modern by defining its ‘others’, cities and people who are not viewed as modern, and therefore are excluded as potential sites and authors, respectively, of significant ways of understanding the urban. She refutes ‘these divisions within the field of the urban’, and posits a post-colonial urbanism that recognises ‘differ- ence as diversity rather than hierarchical division’ (4). Viewed from the perspective of the subject under consideration, one needs only to con- sider the constant struggle in western countries to deal with the enormous amount of waste produced to realise this is a worldwide problem which requires multiple solutions at various levels. Perhaps New York City’s Mayor, Bill de Blasio’s effusions on 22 April 2015, [Earth Day], epitomises this global challenge: The whole notion of a society based on constantly increasing waste and then putting it into a truck or a barge or a train and sending it somewhere else – you dig a big hole in the ground, you put the waste in the ground – that is outrageous and is outdated and we’re not going to be party to it. (In Rosengren 2015, ii) By this time, the Department of Sanitation of New York was collecting more than 3 million tonnes of residential and institutional waste per year, with about 16% of that being diverted for recycling and about 12% sent to a waste-to-energy facility in Newark, New Jersey. The remainder travels hundreds of kilometres to landfills in multiple states and the exporting process cost for the Fiscal Year 2016 was estimated at $367,815,000 (Rosengren 2015, iv). Suffice to state that the above discussion is not meant to provide an exhaustive view in how these binaries are engaged in shaping a global, hierarchical way of knowing cities based on their ordering on a singular grid/axis of ‘modern’ or ‘primitive’ (undeveloped), ‘global’ or ‘non-global’ (forgotten) or core versus peripheral (Robinson 2006). It neverthe- less provides an overview of the competing debates and, more importantly, provides an opportunity to unpack the impact of crude dumping on the host communities: their health, properties and livelihoods as well as emissions of methane and leachate JOURNAL OF CONTEMPORARY AFRICAN STUDIES 351 (Nelson, Genereux, and Genereux 1992; Lim and Missios 2007; Botkin 2007; UN-Habitat 2008) from an African perspective. In most developed countries, the hedonic technique, which attempts to infer people’s preferences by the way they behave in the market, has been used to determine the effect of landfilling on property values, with widely differ- ing results (see Havlicek, Richardson, and Davies 1971; Bouvier et al. 2000). However, the situation in most developing countries does not easily lend itself to such analysis due to paucity of data and therefore remains mainly under-researched or, at best, speculative (Arimah 1996; Du Preez and Lottering 2009). How then do we ascertain the extent to which the presence of a landfill threatens nearby communities? Is there evidence that the presence of a landfill potentially destroys development gains and/or accumulated wealth? Recently, a study by Owusu et al. (2014) attempted to address this knowledge gap by exploring the effects of landfills on residential property values in two communities (Oblogo and Mallam) in Accra, Ghana. Their analysis indicates that though landfill does depress nearby properties, the effect is contingent on the communities’ level of urbanis- ation, year of completion and the total costs of the property. Building on this maiden empirical work, and in our attempt to respond to calls on researchers to shift the focus of urban theories as they move from the global North to the South (Parnell and Robinson 2012; Schindler 2015; Myers 2016), we moved beyond these two dumpsites in Accra, (the most urbanised city in Ghana) and sampled nine landfill sites in three major cities: Accra, Kumasi and Wa. These cities were purposefully selected to cover the country’s three broad ecological zones and coincide with the socio-economic trajectories: the coastal zone being the most, and the northern the least endowed finan- cially and resource-wise. Gauging from their level of development, we hypothesise that the location of a landfill can sometimes bring benefits to the host community. Put differ- ently, we opine that in countries like Ghana, saddled with chronic financial, technical, human capacity and attitudinal challenges, the presence of a landfill in an area does not necessarily always assume an inverse relationship, which underpins most western- country-focus discourses (see Bouvier et al. 2000; Owusu et al. 2014). We are not discount- ing a situation where residents in a host community may fear the presence of a landfill can imperil their future health and well-being, though such perceptions may not always be based on reality. We are convinced that adopting a one-size-fits-all principle will negate local practical- ities (limitations), and that it guarantees embedding unsustainable structures, processes and outcomes, and may provide little realistic guidance for policy-makers (EPA 2002; Mahama and Adarkwah 2006). In other words, it may be that certain characteristics of the landfill and the host communities, such as the size, operating status, perceptions, past experiences, and the overall development of the host community may determine the effect on surrounding property values, not the mere presence of one. The remainder of the study is organised as follows. In the next section, we provide a brief theoretical overview regarding landfill nuisance effects on the immediate property market. The third section presents an overview of the processes involved in the selection of landfill sites in Ghana particularly, and outlines the research methodology. The subsequent section then reviews the empirical evidence of possible externalities from our study locations, describing selected city-specific scenarios. Section five interrogates the impli- cations of the findings while the final section draws some conclusions for policy considerations. 352 M. OTENG-ABABIO ET AL. Waste, landfill externalities and property values Broadly speaking, waste refers to unwanted or unusable materials, substance or by-pro- ducts, used synonymously with rubbish, refuse, litter, debris, dross, junk, scrap, etc. and spread across diverse geographies and very active in a variety of cultural contexts (UNEP 2005). When poorly managed, the impact of waste and its constituent parts can be dire, especially for those staying in close proximity, even though several other studies also highlight how many also make a living from such discarded materials (Odama 2013; Grant and Oteng-Ababio 2016). The literature provides various challenges that affect MSWM, including lack of technical skills among personnel within city govern- ments; deficient infrastructure, poor roads and vehicles; inappropriate technologies and lack of engineered landfills (Asase et al. 2009; Hazra and Goel 2009). These challenges, as rightly noted by Moore (2012, 781), have compelled researchers to increasingly use waste as a lens (litmus test) to explore environmental politics (Gandy 2002), urban history (Melosi 2000; Sterner 2008), social behaviour (Barr, Gilg, and Ford 2001), social movements (Cresswell 1996), capitalism (Clapp 2002; Gregson and Crang 2010), modernity (Moore 2009), risk (Bickerstaff and Simmons 2009), regulation (O’Neill 2000) and govern- ance (Davies 2008; Bulkeley and Askins 2009). The significance of the varied conceptualisation of waste (i.e. hazard, object of manage- ment, commodity, resource, archive, filth, fetish, risk, disorder, matter out of place, govern- able object, abject and actant) manifests in the quest for an integrated MSWM, and how the practice impacts on nearby property values (Senkoro 2003). Crecine, Davis, and Jackson (1967) succinctly highlight how environmental features can increase property values if they are viewed as attractive and desirable or vice versa. Referring specifically to land values, Bello and Bello (2008) listed three potential factors, scarcity, utility and desirability, which are highly variable depending on the type of operation, location and development. Principally, the emerging debates can be categorised into three broad trends. The first debate establishes a price–distance decay relationship and argues that prop- erties located close to landfills attract lower prices. For example, Reichert, Small, and Mohanty (1992) studied the impact of five municipal landfills on surrounding residential property values in Cleveland, Ohio, and established a strong correlation between landfill nuisance and nearby property values. In a study by Nelson, Genereux, and Genereux (1992), which adopted an empirical model to estimate the price effects on 708 homes near a Minnesota landfill during the 1980s, it was established that the landfill adversely affected home values by 12% at the landfill boundary and 6% at about 1.6 km. Beyond about 3–4 km adverse effects were negligible. The proponents of this school of thought, however, seem to be having a priori normative assumptions about how landfills impact properties but fail to empirically situate and conclusively substantiate these asser- tions geographically. A second strand of literature examines landfill size and property values and maintains that, generally, larger landfills are associated with greater externalities, manifesting in the use of higher volume waste trucks, larger parcels of land and a longer period of post- closure stabilisation. Lim and Missios (2007), for example, examined property values of houses located in the proximity of two landfill sites of significantly different sizes in Toronto, Canada. Their results suggested that large landfills have relatively greater JOURNAL OF CONTEMPORARY AFRICAN STUDIES 353 adverse impact on property values, implying the markets reflect difference in external costs. Gamble et al. (1982) also conducted a case study in Montgomery County, Pennsyl- vania, and found a negative effect on property values, though the results were not statisti- cally significant. One challenge with this debate, however, relates to how to define what is a ‘small’ or ‘large’ landfill. The third school employs the theory of enclosure or exposure and argues that a landfill with appropriate buffers has statistically insignificant or even no impact on property values (see Zeiss and Atwater 1989; Clarion Associates 1991). To put it simply, proponents argue that a landfill which is location-restricted and operates out of view of nearby communities is unlikely to impact property values negatively. A study which examined the development effects of landfills on residential properties at four sites in the USA revealed that the land- fills did not impose negative price effects and, indeed, in some situations they found that landfills actually increased property values and were associated with greater residential development (see Research Planning Consultants Inc. 1983). The observation resonates with the study by Bleich, Findlay, and Philips (1991) which revealed that, if well managed, landfills can be good neighbours with no statistically measurable impact, and that they can even improve infrastructural provision and create job opportunities. Fundamentally, these arguments are closely related but provide inconclusive evidence. One commonality among these debates relates to their failure (inability) to take into con- sideration the perculiarities of the sub-region, such as differences in the level of socio- economic development. For example, in Ghana, until 2004, landfill remained the exclusive and most preferred, prevalent and endorsed waste disposal option (Owusu, Oteng- Ababio, and Afutu-Kotey 2012; Oteng-Ababio 2013). This is in spite of the fact that the gov- ernment had prepared landfill operational guidelines since 2000 (see EPA 2000). A review of the guidelines (see Oteng-Ababio 2010) – which is beyond the current scope – found that they mimic or were developed through the lens of developed countries, making its strict operationalisation challenging. Equally important challenges relate to the issue of spatial planning, which, in many developed economies, is a matter of course, but in Ghana, this has been overshadowed by the domain of socio-economic planning. Yet, for all intents and purposes, spatial plan- ning was an integral to the economic policies of the country during colonial rule (Fuseini and Kemp 2015). While the colonial governments employed spatial planning on limited scale and for exploitative purposes, post-colonial governments have implemented broad-based planning grounded in the ‘genuine’ aspiration to promote a spatially balanced development. However, overwhelming evidence points to the fact that post- independence planning has not been as successfully implemented when compared to pre-independence planning due to a myriad of factors including rapid urban growth, inadequate staffing, low capacity, lack of institutional coordination, political interference in planning, complex land tenure and evolving landmarkets, thus creating a myriad of pro- blems that are inimical to sustainable urban development. This partly explains the many illegal dumpsites, most of which are located in peri-urban zones. These are zones where land had long degraded through illegal quarrying and sand winning, a practice tacitly endorsed by most city authorities. We hypothesise that site-specific characteristics may be one of the largest determinants of whether a landfill affects property values. To wit, such ‘overtly’ and poorly managed dumpsites in Ghana may cause social and aesthetic 354 M. OTENG-ABABIO ET AL. nuisances, but their impact on property values remains speculative, a knowledge gap this study contributes to bridge. The research localities and methodology Selection of waste disposal sites As already noted, landfills have become one of the vital components in any well-designed MSWM system and the ultimate repository of a city’s waste after all other management options are completed. According to Ghana’s Environmental Protection Agency (EPA) (2002), properly managed landfills guarantee environmental friendliness, social acceptabil- ity and financial sustainability, without impairing human and environmental health. To achieve this calls for sound spatial planning, administration and management. Also, the location and size of the facility, the level of interested parties participation and the elim- ination of fatal flaws1 including sensitive environments and water resources are strategi- cally critical (see EPA 2002). Table 1 outlines basic requirements for operating safe disposal of waste in landfills. Operationally, the use of landfill tends to be over-generalised and therefore city auth- orities do not follow or maintain them stringently as stipulated in the EPA guidelines. Ghana’s experience with landfills began in 1994, when a World Bank (Urban III) Project tar- geted 11 district capitals (see Table 2). In 1995, five major cities: Accra, Tema, Sekondi- Takoradi, Kumasi and Tamale were further targeted. A study by the local government (see Oteng-Ababio 2013), however, shows that due to issues related to land acquisition and endless litigations, work on the first 11 projects stalled while only 3 of the 5 initiated in 1995 were completed after almost a decade. In seeking robust statistical evidence for the study, three landfill sites in each of the three cities – Accra, Kumasi and Wa – were sampled. Table 2 summarises some of the challenges, which differ in character and severity, encountered during the sites selection. According to Oteng-Ababio (2011), the Accra site, for example, hit a snag when the landowners vehemently and wilfully resisted govern- ment’s renewed efforts to break ground in 2002. These challenges made the burning of waste, which causes plumes of smoke to cover the urban space and implicitly creates ter- rible problems with odour and ecological hazards, the easiest disposal option (Post and Obirih-Opareh 2002; Post, Broekema, and Obirih-Opareh 2003; Simon 2014). What remains unclear, however, is how such practice impacts property values geographically, particularly in the peri-urban communities which are normally delegated (disconnected) and poorly serviced. The research locations The Accra case study Accra is the national capital and the economic, administrative and cultural hub of Ghana. Its geographical location allows it to function as a natural port, and this explains its pros- perity (Grant 2009; Oteng-Ababio 2013). The city has grown significantly from a population of 20,000 in 1891 to 135,800 by 1948, reaching 2 million in 2010 (GSS 2012). With an annual growth rate of over 4%, Accra is one of the fastest-growing cities in the country; yet JOURNAL OF CONTEMPORARY AFRICAN STUDIES 355 Table 1.

JOURNAL OF CONTEMPORARY AFRICAN STUDIES 357 years since 2002, thus breaching EPA’s guidelines with impunity and raising questions as to whether the dumps are ‘a blessing or a curse’ for the people they are to serve. With a floating population of one million a day (Grant and Yankson 2003), the unplanned nature of disposal sites in Accra has made the negativities of waste disposal conspicuously noticeable, exacerbating the ‘Build Absolutely Nothing Anywhere Near Any- thing’ (BANANA); For-Not-On-Our-Street (NOSS) or ‘Not-In-My-Back-Yard’ (NIMBY) atti- tudes of some residents. The Oblojo dumpsite presents a microcosm of such public disenchantment. For example, an earlier study by Owusu, Oteng-Ababio, and Afutu- Kotey (2012) recorded that as a trade-off for using an abandoned quarry as a dumpsite, the city authorities undertook to provide certain infrastructure services but failed to follow through; hence, after four years in operation, residents resorted to daily protests, and eventually began preventing waste trucks from accessing the site (see Figure 1). Currently, there are only three disposal sites serving the city and apart from the Oblojo site, none operates with permits. A study by the Parliamentary sub-Committee on sani- tation (PAR) in 2011 revealed that since 2000, Accra Metropolitan Area generates averagely between 2500 and 3000 tonnes of waste daily but collects only between 1800 and 2000 tonnes at a financial cost of GH¢18,000 (US$12,000) (PAR 2011). Specifically, the study noted that the city spent about 62% (US$4.38 m) of its internally generated funds on waste collection in 2005, increasing to 72% and 77% in 2006 and 2007, respectively. The three sites sampled for the study are Kwabenya, Oblojo and Pantang. This approach to MSWM is relatively different from what pertains in, for example, Sweden, where the authorities adopt a hierarchical approach: first, waste should be reduced through re-use and recycling, next incinerated and, only if nothing else works, landfilled. The Kumasi experience Kumasi is Ghana’s second-largest city and, like the narratives above, illegal dumping of waste has been the bane of the authorities for years (Tipple 2005). Though the city bene- fited from one engineered landfill under the World Bank Project, open dumping practices dominate the urban landscape as in Awhiaa (near Tafo); and Kwadaso, a heavily populated Figure 1.

These have dented the aesthetic image of otherwise beautiful and well-planned middle-class communities. The engineered landfill is located at Dompoase, about 15 km southwest of Kumasi. The construction started in 1998 and completed in 2004, with a lifespan planned till 2018. Operationally the site, which covers about 100 ha of prime farmland, is equipped with concrete-lined basins for the collection of leachate. Financially, the city, with about 70% collection rate since 2005, spends approximately US$491,730 a month on waste collection and disposal, with US$250,000 used monthly to maintain the Dompoase landfill (Oteng-Ababio 2013). The state of affairs mirrors that of Accra and for the empirical study, the Dompoase, Ahwia and Kwadaso disposal sites were selected for in-depth studies. Insights from Wa The city of Wa, the youngest of the 10 regional capitals, had a population of 13,740 in 1970, 36,067 in 1984, 66,644 in 2000, with the 2010 population census recording 71,083 and a growth rate of 4% (GSS 2002, 2012, 2013; WMA 2012). The city generates 54 tonnes of waste daily and has a 45% collection rate (Zoomlion 2013, cited in Amoah and Kosoe 2014). Constitutionally, the city authority is mandated to provide waste management ser- vices to residents, a mandate activated in 2006 when it partnered with Zoomlion Gh Ltd. In the same year, the city benefited from a fenced and gated World Bank-sponsored 40-acre landfill initiated in 1998 at Siriyiri, a distance of 15 km from the city centre. Until this time, the city had depended exclusively on open dumpsites, which had orga- nically emerged in most communities, including Wapaani, Kambali, Bomiyiri and Kpaguri. Typically, Wa’s situation is not unexpected, gauging from the city’s position on Ghana’s urban hierarchy. Indeed, infrastructure needs present a unique dilemma. In 2010, the city had approximately 8505 residential units but only 1 public water closet, 12 Kumasi Ventilated Improved Pits, 53 approved refuse dumps and 1008 unapproved sites (GSS 2012). Thus by inference, one unapproved dump could be cited within a cluster of eight residential units and it was not uncommon to see containers, whose collection period had sometimes been delayed for weeks (Amoah and Kosoe 2014). Surprisingly, both adults and children engage in open defecation around these sites. The sampled research locations are Siriyiri, Wapaani and Kpaguri. Data collection and analysis As already noted, most studies, which typically seek to estimate the impact of landfills on property values, have used the hedonic price technique (Havlicek, Richardson, and Davies 1971; Bateman, Day, and Lake 2004), but this technique appears unsuitable in Ghana, where reliable cross-sectional data needed for such analyses remain greatly patchy and non-existent (Aryeetey et al. 2007). Consequently, our research adopted multiple method models including questionnaires, in-depth interviews, focus group discussions (FGDs) and direct observation to generate enough data. The discussions are captured through the lens of those living in and around these LULU2 facilities and complemented with the past and present land values and rent charges, which were used as proxies for property values. This was deemed appropriate since most peri-urban areas where cities tend to consolidate their municipal waste remain highly underdeveloped and generally JOURNAL OF CONTEMPORARY AFRICAN STUDIES 359 suffer from unavailability of the data. Our initial visits had revealed that these areas do not have as many ‘quantifiable houses’, in some cases (e.g. Siriyiri, Dompoase and Kwabenya) with a 2-km radius and therefore not as much data. Our fieldwork, which spanned February to May 2014, saw each key researcher working alongside two assistants fluent in the dominant local language and being assigned to a city with a comparative advantage in terms of local knowledge and social links. In the field- work itself, the global positioning system (GPS) devices were used to measure a 500 m buffer radius from the edge of a particular landfill,3 and the landlords or their representa- tives within this buffer were randomly interviewed. The survey was administered to a total of 1450 residents, proportionately shared among the three cities and randomly sampled from each of the three research locations. Of these, a total of 1300 responses were received, made up of 806 (62%) men and 494 (38%) women, giving a response rate of almost 90%, which was considered high for the purpose of the analysis. The questionnaire sought details on respondents’ demographic characteristics and the landfills in question. Others also related to any observed ecological hazards including land value changes, and any emerging ‘stigma’. Information on land values and rents charges were also sought and operationalised as proxies of possible environmental disamenity, although these values in most low-income and peri-urban areas are generally low due to their peculiar standards and characteristics regarding housing types, style, convenience and access to social ame- nities (Konadu-Agyemang 2001). As part of the data collection process, 27 key informants including traditional leaders, self-appointed community representatives and local government officials were inter- viewed. These interviews focused mainly on any perceived ecological hazards of operating landfills on land values in the community. Additionally, one FGD was conducted in each study location. Ideally, participants were to be selected randomly by the research team. Yet in the field, this was found to be unfeasible logistically due to local politics, thereby compelling the team to rely on the local assemblymen4 for assistance. Although this tech- nique may have created political biases and may not have reached all sections of the society, it was felt to be the most workable compromise. Participants were given the opportunity to withdraw their involvement at the beginning and even at the end of the sessions, thereby forestalling the issue of people consenting due to pressure from a respected community leader. In spite of the challenges, participants sampled gave a range of sexes, ages, geographi- cal locations and included not only landlords (or their representatives) but also youth leaders and opinion leaders within the study locations. To elicit objective and uncon- strained responses from all participants, efforts were made to make all participants com- fortable and able to participate fully. The meetings, therefore, were peppered with humorous stories, brief relaxation periods and refreshments at strategic intervals. All inter- views were voice recorded, transcribed and thematically analysed, and collectively pro- vided substantial information to analyse our objectives. To statistically determine whether a landfill affects property values, we use ‘before and after’ land values as proxy indicators and calculated the mean t-test. As part of the data collection processes households were presented with a Likert scale to measure whether, within the past 10 years, the value of land had gone up, stayed the same or gone down. We also examined land values before and after the introduction of the LULU facility as well as rent charges across the various geographies within each city. The findings were 360 M. OTENG-ABABIO ET AL. insightful, revealing and informative. Though the use of indicators and indices to measure attributes of interest for a system continues to garner momentum in the literature, there is the tendency to reduce the complexity of the interactions to just a particular variable or set of variables. Nonetheless, due to the fact that some interactions are very difficult to quantify, and development is mainly human-centred (Moore 2011), we firmly believe that this approach provided the best level of methodological consistency of publicly available data. The LULU externalities: getting the fundamentals right Examining respondents’ perceptions on landfill–land value interface As stated earlier, empirical work on the nexus between landfill and property values is not always adequately captured economically, and is often disfigured by lack of data. To cir- cumvent the challenge, we sampled three sites in each city. All three sites sampled in Accra were within the peri-urban zones, while in Kumasi and Wa, only Dompoase and Sir- iyiri, respectively, fell within that zone. Generally, a major distinguishing characteristic finding is that the landfills in the peri-urban zones are not easily visible. They were tucked out of sight in mostly deprived environments, unlike those located in the built environment (e.g. Kwadaso, Ahwiaa, Wapaani and Kpaguri). Table 4 displays the results of the Likert-scale responses of participants’ perceived impact of landfills on land values in their respective communities. The results show that overall, 45% of the responses indicate a positive impact of landfills on land values with 35% and 20% indicating indifference and negative externalities, respectively. A critical examination of the responses, particularly those from the peri-urban areas, which are lit- tered with abandoned quarry pits, which needed reclamation anyway and were virtually inaccessible (unknown) prior to the construction and operation of the landfill, revealed nuanced geographical effectual variations. In all, 61% of respondents from Kwabenya, 84% from Dompoase and 75%t from Siriyiri display extremely high positive impacts with the construction of their respective landfills. The case of the Kwabenya landfill project saga clearly demonstrates one instance where ‘landfill’ produces fewer (negative) externalities. A previous study revealed that the area was a highly degraded stone quarry that had remained un-noticed for decades until acqui- sition by the local government for the LULU facility (Oteng-Ababio 2011). Consequently, the area became so visible and spontaneously generated a mad rush for residential plots within the ‘acquired land’ after the government had constructed a 2 km bitumen road to the site. The embedded positive externalities was collaborated by a community leader during the community’s FGD who stated: ‘Indeed, but for the proposed landfill, Table 4. The construction of landfills and variations in land values. Annual increment in land values City 1998 2008 GHC Per cent Accra 150 6000 585 98 Kumasi 100 4500 440 98 Wa 100 1500 140 93 Source: Fieldwork, 2013/2014. JOURNAL OF CONTEMPORARY AFRICAN STUDIES 361 the possibility of even a footpath reaching this area any time soon would have been a wishful thinking’. The Kwabenya case is not an isolated issue. It mirrors the case of ‘Tantra Hill’, one of the high-income neighbourhoods in Accra today. According to Songsore et al. (2008) the area was an abandoned quarry site, and between 1970 and 1980 (see Figure 2) housed one of the biggest ‘waste disposal sinks’ in the metropolis. Yet, with improved accessibility to the site (courtesy of landfilling) the area has defied all odds to become one of the addresses for high-income communities in Accra today. The result from Kumasi is however mixed. With the exception of the Dompoase site, the other two research locations were already heavily populated, and well-developed infra- structure-wise, before the LULU facility was established. Kwadaso, for example, is already a well-functioning middle-class neighbourhood (see Bank of Ghana 2008) while the genesis of the Awhiaa dumpsite on the other hand is traceable to continuous illegal dumping into an open space, which did not attract official attention in time. To statistically validate and determine if the responses from the research locations were significantly different, the Student t-test was employed (Table 5) to compare their mean responses. Operationally, this was achieved by coding the negative responses by 1, indifferent by 2 and positive by 3. By implication, a higher mean connotes more positive responses and vice versa. The results show that there are more positive responses in Accra and Wa than in Kumasi, all at 1% significance level. The high positive responses in Accra and Wa mean that there is a high probability of rejecting the null hypothesis (i.e. landfill in those research locations negatively affect property values) and vice versa.

Indifferent indicates a business-as- usual scenario. Comparative analysis of land values Our study captured information on land value variations in the host communities before and after the introduction of the LULU facility. The results (see Table 6) depict a character- istically similar pattern, with land values in peri-urban communities showing considerable appreciation than those in the relatively developed areas. In Accra, the land values in Kwa- benya, for example, appreciated from GH¢150 (US$100) in 1998 to GH¢6000 (US$4,000) in 2008. Similar observations were made in Kumasi (Dompoase) and Wa (Siriyiri), where both sites witnessed an average of 98% or 93% land value appreciation during the same period after their respective landfills were constructed. Incidentally, the Dompoase and Siriyiri sites are among the only four large landfill sites in the country, all of which were sponsored by the World Bank. As already emphasised, the LULU facilities are normally sited in peri-urban areas, where incidentally land for such facilities is ‘affordably available’. Characteristically, these are areas where portions of the land have suffered severe environmental degradation and are chronically deficient in basic social services and infrastructure. Meanwhile, increasing urbanisation has accentuated the demand for residential plots from the rising middle class (Grant 2015). Such sentiments were often expressed by many participants during the FDGs in all three peri-urban communities and these are not without scientific basis. In Siriyiri, during an FGD, a local opinion leader remarked: … but for the landfill, we would have remained isolated. We hardly went to town and stran- gers also hardly came here. Today, the story is different; the refuse truck move up and down on an hourly basis; and even the taxis too. Table 6. Results of the Student t-test to compare the mean responses of respondents.

This was particularly endorsed in the FGDs, when participants unanimously agreed that the construction of three bridges over the River Oda, and the provision of water and electricity had greatly opened up and promoted economic activities in their communities, which hitherto had been cynically christened ‘Kuwait’, ostensibly owing to the areas’ deprived nature and limited accessibility (Owusu-Sekyere 2015). During another FGD, similar sentiments were captured: Sixteen years ago, prior to the building [sic] of the landfill, no commercial driver was prepared to come here, and those who dared always returned with one dysfunctional [vehicle] part or the other.… . The price of a piece of plot was less than GH¢100 [US$66.7]… . Today, a land plot is GH¢4,500 [US$3,000], and even then one needs an agent. When probed further, a new sense of enlightenment became apparent, which was syno- nymously correlated to positive externalities of landfills. Narratives would often include the term anibue (‘eye-opening’ (associated with modernity)) as one of the immediate impacts of the construction of the landfills in their respective communities: Even though we still battle [swamps of] files and mosquitoes, we can’t forget the other side too; today most of our children go to school, not only because there is market for our products [farm products and land]; we [wives inclusive] can also collect condemn [metal/other scraps] for sale. Lives have really changed! By inference, we can draw a tentative conclusion: the infrastructure limitations notwith- standing, the presence of the landfills in deprived peri-urban zones potentially serve as a catalyst for the provision of hitherto deficient services, leading to a population influx (explosion) and subsequently, the appreciation of property values. Does the presence of landfill affect rent? We acknowledge that the paucity of cross-sec- tional data used in hedonic price analysis (Pamlquist 1999; Freeman 2003) makes direct attribution between respondents’ perceived variations in land values to the presence of the landfills or otherwise quite challenging. We therefore complemented our findings with current rent charges where possible. Our findings did not vary considerably from the earlier observations. In Kumasi, for example, during an FGD discussion in Kwadaso (Kumasi), over two-thirds of the participants, including a pensioner, recounted severe dis- amenity (especially strong stench) as a result of the landfill. One landlord remarked: ‘My son, I wish I could charge like GH¢50 [US$33.3] a month, but when they [tenants] come they complain about this stench and the many visible flies they see around’. Similar senti- ments were expressed by a tenant at Awhiaa (Kumasi) when discussing the impact of the presence of a landfill near rented apartments: ‘As for me, I have asked the landlord to reduce my rent from next year [2015] because, my brother, come and see mosquitoes in the evenings. The problem is even worst after heavy downpour’. These observations contradict the result from Wa, where 90% of responses from Siriyiri quantitatively indicated that the construction of the landfill has impacted positively on land values. Until the landfill began operations, most dumpsites in Wa were located within poorly managed indigenous communities, where property values were and remained exceptionally low. For example, a single room in an indigenous community which is in the centre of the city attracts a rent of GH¢350 (US$233.33) per annum, as 364 M. OTENG-ABABIO ET AL. against GH¢450 (US$300) some 500 m away. During the fieldwork, we particularly observed that many new developments and convenience shops were ironically springing up around the Siriyiri landfill, including even the government’s planned Affordable Housing scheme. Discussions In accordance with the previous research on the impact of landfill on property values (Owusu et al. 2014) and in light of the evidence presented, we find mixed support for the thesis of the negative impact of landfills on property values. Such findings make it dif- ficult to draw definitive or even generalised policy conclusions and therefore call for a broader contextualisation of the socio-spatial dynamics in property values. At the very least, the regions’ level of socio-economic development and the type of landfill collectively interact with other factors to leverage the impact on property values. In the absence of any generalisations, it seems that each landfill should be studied on a case-by-case basis to determine whether it affects the surrounding property values. So far, our study contradicts some of the earlier studies (Gamble et al. 1982; Lim and Missios 2007) that large landfills affect property values more than small ones. For example, the study revealed that Dompoase and Siriyiri were the biggest landfills in the current study, yet their impacts on property values were statistically insignificant. Indeed, the results show a positive correlation between the presence of landfills and land values in their host communities. Our results resonate with Bateman, Day, and Lake’s (2004) study in Birmingham (UK), which shows that the impact of distance to the nearest landfill site on property values ‘are not consistently negative’. It further confirms Amoateng, Cobbinah, and Owusu-Adade’s (2013) peri-urban studies in Kumasi (i.e. Abuakwa) which indicated that the area’s indigenous people, who are mainly farmers, are being denied their livelihood since ‘an upsurge in land value from GH¢250 in 1993 to GH¢5,000 in 2010 is pricing out the indigenes and low-income earners from the land market’. Significantly, our examination of the landfill–property value thesis, took into consider- ation the prior socio-economic conditions of host communities – something earlier studies have virtually overlooked. The findings has set the stage of ‘righting the wrong’ for policy overlap of prior conditions in appreciating and understanding the impact of landfill on property values. More importantly, our results provide enough evidence to suggest that, under certain circumstances, the introduction of a landfill into host communities can serve as a catalyst towards the correction of the ills of development, including poor gov- ernance, attitudinal and financial constraints. Consequently, we suggest that attempts to over-generalise the negativities associated with landfills will not only be a major opportu- nity lost for poverty alleviation, but a recipe for compounding the already precarious con- ditions of most urban poor, many of whom compete for space in peri-urban areas where waste tends to be poorly managed. These findings can, with further elaboration, provide the basis for re-thinking our current waste disposal policy. Overall, the evidence suggests that in order to pursue a more sustainable MSWM, local government policies may have to be rebalanced towards assigning appropriate priorities and support to waste prevention activities, priorities and support that have so far received lip-service within Ghanaian environmental policy JOURNAL OF CONTEMPORARY AFRICAN STUDIES 365 principles (see EPA 2002; MLGRD 2010) but are never effectively implemented. In addition, the authorities may need to adopt measures either through adaptive local resource man- agement or through adjustment in existing human systems. Situations where land is allowed to be wantonly degraded (e.g. through sand winning) to justify future landfilling are unsustainable and must be discouraged. The role of a local government’s decentralisation process in achieving the objective cannot be underestimated. This calls for proper stakeholder consultation (going beyond the NIMBY syndrome), which listens to the voice of the voiceless in society, which is indispen- sable and necessary to ensure any successful outcomes. The local authorities must also ensure that policies advanced pass through implementable stages. For example, although the EPA policy guidelines enjoin all local governments to operate sanitary landfills, policy efforts so far have been biased towards ‘illegal’makeshift disposal practices (with tacit endor- sement from local authorities). The impact of such disposal practices on land and property values may not be sufficiently significant today; however, future pressure on land and increased consolidation of waste in peri-urban zones may induce people to engage in socio-economic ventures which will bring a multitude of deleterious effects in their wake. Conclusion and policy implications Our study finds exceptionally skewed support for the current thesis on landfill–property values. Generally, the price–distance decay model and landfill size and property values relationship seem applicable only if the landfills are cited in an already developed, urba- nised and expanded neighbourhood, with basic infrastructure services and investments in technology. However, this strategy does not attain a national optimum, given the under- developed and degraded nature of most peri-urban areas. The main findings reinforce arguments by the proponents of the enclosure or exposure discourses. The overarching argument from studies such as those by Research Planning Consultants Inc. (1983) and Bleich, Findlay, and Philips (1991) proposes that landfill with appropriate buffers has no externalities on property values. In a non-western context, Owusu et al. (2014) highlighted the significance of the communities’ level of urbanisation (development) in the whole equation. The findings here indicate much less gross economic cost when landfills are cited in peri-urban areas. With more challenging infrastructure provision, the construction of a landfill becomes a lesser expensive development abatement option. To illustrate, the Kwa- benya saga has been repeatedly cited. Similarly, it was unanimously established that the construction of three bridges over the River Oda, in Dompoase (Kumasi) and the provision of water and electricity had greatly opened up and promoted economic activities in adjoining communities (see Hendriks, Blok, and de Jager 2001). The broader question of the effects of landfill on property values is of interest to both policy-makers and scholars concerned with environmental management. One important caveat however remains. Further empirical epidemiological research is necessary to compare and ascertain the socio-environmental costs associated. Moreover, most landfills do not recover energy, and leaking is often a serious problem, especially for older landfill sites. These types of landfills may be less costly to implement than our modern sites, but their environmental costs can be prohibitive. Therefore, proper treatment of and energy recovery from landfills are some of the more important targets for waste policy. 366 M. OTENG-ABABIO ET AL. Notes 1.
