Item 18S and ITS1 genomic sequence variations in Rotylenchulus reniformis isolates from Alabama(Journal of Cotton Science, 2013-01) Nyaku, S.T.; Kantety, R.V.; Tilahun, Y.; Lawrence, K.S.; Soliman, K.M.; Cebert, E.; Sharma, G.C.Upland cotton, Gossypium hirsutum L., is highly susceptible to infection by reniform nematode (Rotylenchulus reniformis), which can cause over 10% reduction of cotton yields in Alabama. Detection of reniform nematode (RN) and analysis for molecular variation within its population is important for understanding its interactions with cotton and other host plant species. Restriction analysis of PCR products of ITS1 regions was achieved using four restriction enzymes, HaeIII, HhaI, MspI, and RsaI. These showed similar banding patterns for both male and female populations. However, MspI digestion of ITS1 amplification products showed variants within the combined sex and location effects primarily attributed to a 500 bp fragment that was absent in other restriction digestions. Intra-nematodal variations in 18S and ITS1 rDNA were studied in detail by sequencing a minimum of ten clones in each individual male and female RN isolates in both directions. Multiple sequence alignment of the 18S rDNA sequences showed two major types of sequences within this gene for both male and female RN clones, which could be distinguished at 27 specific sites. Two distinct ITS1 fragments of lengths (550 bp and 720 bp) were observed; referred to as ITS1S and ITS1L respectively. Neighbor-joining analysis was used in revealing the relationships and grouping characteristics between male and female RN clones, with clones grouping together irrespective of sex and isolate. Sequencing of one-third of the 18S and ITS1 rDNA regions provided clear evidence of intra-and inter-nematode variability, in addition to gene conversion events in the 18S rDNA of individual male and female RN clones. © The Cotton Foundation 2013.Item Ability of the larval ectoparasitoid Habrobracon hebetor (Say, 1836) (Hymenoptera: Braconidae) to locate the rice moth Corcyra cephalonica (Stainton, 1865) (Lepidoptera: Pyralidae) in bagged and bulk stored rice [Wirtsfindung des larvalparasitoiden habrobracon hebetor (say, 1836) (Hymenoptera: Braconidae) in gesacktem und geschüttetem reis gegenüber der reismotte Corcyra cephalonica (Stainton, 1865) (lepidoptera: Pyralidae)](Journal of Plant Diseases and Protection, 2010-04) Adarkwah, C.; Büttner, C.; Reichmuth, C.; Obeng-Ofori, D.; Prozell, S.; Schöller, M.The potential of using Habrobracon hebetor for the inundative biological control of Corcyra cephalonica in rice stored in jute bags and in bulk was assessed. Host-finding in the situation of bag storage was tested by preparing small jute bags measuring 18 × 16 cm filled with 5 kg of un-infested rice grains. In the first experiment, 60 larvae of C. cephalonica were released into the bag. The bag was placed in an empty climatized room with an area of 12.3 m2. Sixty H. hebetor adults (sex ratio of 1 male: 2 females) were released at a distance of 1.6 m away from the jute bag. The number of H. hebetor adults that entered the jute bag was counted daily for 8 days by opening the bag and counting the parasitoids. Only 3% of the parasitoids entered the jute bag. In a second experiment, 60 C. cephalonica larvae were placed inside a wire gauze cage within the jute bag. Ten H. hebetor adults were released into the jute bag. The bag was sealed. After 1 week the cage was removed, and the number of C. cephalonica as well as F1 generation of H. hebetor that emerged was recorded. H. hebetor was able to significantly reduce the number of C. cephalonica emerging from the bagged rice; the corrected mortality due to the parasitoid release was 92.13%. The emergence of H. hebetor progeny started on day 9 after the introduction of the parasitoids and continued until day 21. Host-finding in the situation of bulk rice was tested in glass cylinders (50 cm height, Ø = 25 cm) containing caged larvae at horizontal depths of 7 and 14 cm. H. hebetor was able to find its host C. cephalonica in both depths; significantly more F1 H. hebetor adults emerged from hosts placed 7 cm deep. The implications of these results with respect to the suitability of H. hebetor for the biological control of C. cephalonica in bagged and bulk rice are discussed. © Eugen Ulmer KG, Stuttgart.Item Abnormal pricing in international commodity trading: Evidence from Ghana(International Economics, 2022) Ahene-Codjoe, A.A.; Alu, A.A.; Mehrotra, R.mispricing of international trade in natural resources contributes to significant tax base erosion from developing countries but is difficult to measure using aggregate trade statistics. In this paper, We apply a novel approach motivated by legal rules for trade and transfer, mispricing. to estimate. abnormal pricing in gold and cocoa exports from Ghana, i.e., exports valued outside an assumed arm's length price range that indicates fair market values. Using daily frequency, transaction-level data from Ghana Customs, our results indicate abnormally undervalued exports of gold and cocoa from Ghana equalled USD 8.8 billion in constant prices (base year 2011) or USD 4.1 billion in current prices between 2011 and 2017. Approximately 11% of gold dorm exports and 1% of cocoa bean exports, and 7.2% of cocoa paste exports appear abnormally undervalued. The implied corporate tax base erosion equals USD 2.2 billion in constant prices (base year 2011), corresponding to an average annual decrease of 0.3% in Ghana's tax-to-GDP ratio.Item Access to Rural Bank Credit in Ghana: The case of women farmers in the Upper East Region, Ghana(Ghana Journal of Development Studies, 2009) Akudugu, M.A.; Egyir, I.S.; Mensah-Bonsu, A.Credit is an effective tool that can be used to turn life around for a person, a family or transform self-image, unlock potential and boost the productivity and well-being of the poor. This paper examines the extent of women farmers’ access to credit from Rural Banks (RBs) in the Upper East Region of Ghana. Data were collected from randomly sampled 200 women farmers from four districts and from the archives of the RBs in the region. Semi-structured questionnaire, focus group discussions and key informant interviews were used for data collection. Growth rates of credit supplies and factors influencing women farmers’ credit access were estimated. The results of the empirical study revealed that the growth rate of credit supply by the RBs from 1998 to 2007 was about 18 percent per annum. Besides, credit supply to women grew at a lesser rate (18%) than that of men (19%) during the period. Factors influencing women farmers’ extent of credit access were found to be age, interest rates, farm size, association membership and formal education, among others. Hence, it is recommended that credit supply to women should be improved if the MDGs, particularly those on poverty and hunger reduction as well as gender equality and empowerment are to be attained.Item Accessibility of Rice Farmers to the Ghana School Feeding Programme and its Effect on Output(Agris On-line Papers in Economics and Informatics, 2015) Shaibu, A.F.; Al-Hassan, R.M.The Ghana School Feeding Programme (GSFP) is the Ghanaian version of a Home-Grown School Feeding Programme (HGSP) that has a mandate to give one hot meal a day to school children in public schools from kindergarten through to primary six. The programme was launched in 2005 with the goal of contributing to poverty reduction and increased food security in Ghana. One of the key objectives of the programme is to boost domestic food production by sourcing GSFP raw materials locally, and providing a sustainable market for local food producers in the community. To analyse accessibility of rice farmers to the Ghana School Feeding Programme and its effect on production in three districts of the Northern Region of Ghana, a formal cross section survey of 100 small holder rice farmers was conducted. The transcendental logarithmic production function was applied to analyse the programme's effect on rice output in the three districts using access to the GSFP and other input variables. Our results show that farm labour, farm size, and fertilizer application were significant in increasing farmers' output while access to the GSFP market was not. Again there is no significant difference between the output of those who had access to the school feeding programme and those who do not.Item Accounting for Weather Variability in Farm Management Resource Allocation in Northern Ghana: An Integrated Modeling Approach(Sustainability, 2023) Adelesi, O.O.; Kim, Y-UK.; Adiku, S.G.K.; et al.Smallholder farmers in Northern Ghana face challenges due to weather variability and market volatility, hindering their ability to invest in sustainable intensification options. Modeling can help understand the relationships between productivity, environmental, and economical aspects, but few models have explored the effects of weather variability on crop management and resource allocation. This study introduces an integrated modeling approach to optimize resource allocation for smallholder mixed crop and livestock farming systems in Northern Ghana. The model combines a process-based crop model, farm simulation model, and annual optimization model. Crop model simulations are driven by a large ensemble of weather time series for two scenarios: good and bad weather. The model accounts for the effects of climate risks on farm management decisions, which can help in supporting investments in sustainable intensification practices, thereby bringing smallholder farmers out of poverty traps. The model was simulated for three different farm types represented in the region. The results suggest that farmers could increase their income by allocating more than 80% of their land to cash crops such as rice, groundnut, and soybeans. The optimized cropping patterns have an over 50% probability of increasing farm income, particularly under bad weather scenarios, compared with current cropping systems.Item Achieving carbon neutrality in Africa is possible: the impact of education, employment, and renewable energy consumption on carbon emissions(Carbon Research, 2024) Elom, C.O.; Ankrah, D.A.; Defor, E.W.; et al.This paper analysed the causal link between education, employment, renewable energy consumption and carbon emissions in Africa, where there is scant evidence. Relying on panel data obtained from the World Development Indicators for thirty-two African countries covering a period of 19 years, and fve panel rigorous regression mod els, we found that renewable energy, investment in education, school enrolment, net national income per capita, and employment had negative and signifcant efects on carbon emission, thus increasing these predictors would result in signifcant reduction in carbon emission in Africa. We identifed a bidirectional causality between carbon emissions and net national income per capita, education expenditure and renewable energy consumption, and car bon emissions and employment. Our fndings suggest that investment in education, renewable energy, and employ ment are relevant in mitigating carbon emissions in Africa. We recommend African governments to invest heavily in education, improve school enrolment, environmental education, renewable energy and employment provision to mitigate carbon emissions.Item Acidity and Aluminum Speciation in Biochar Amended Tropical Soils(Taylor & Francis Group, 2022) Eduah, J.O.; Nartey, E.K.; Abekoe, M.K.; Asomaning, S.K.; Essibu, J.K.; Henriksen, S.W.Soil acidification in the tropics has become a more pressing issue due to its associated aluminum (Al) phytotoxicity. The chemical reactive nature of biochar can alter Al speciation in soils. The study assessed the chemical properties and Al speciation in a Ultisol and an Oxisol amended with corn cob (CC) and rice husk (RH) biochars charred at 300, 450 and 650°C in an incubation study for 120 d. pH was determined periodically while organic carbon (OC), cation exchange capacity (CEC), exchangeable base cations, exchangeable acidity, and exchangeable Al3+ were measured at the end of the incubation period. Dissolved organic carbon (DOC) and pH were also determined in soil solution from each treatment. Throughout the incubation period CC and RH biochars significantly increased soil pH, with CC biochar showing a greater effect. Similar effects were also observed for OC, CEC, and exchangeable base cations (Ca2+, Mg2+ and K+). Soil exchangeable Al3+ and exchangeable acidity, soluble Al and Al3+ activity in soil solution decreased significantly upon biochar application; it was more significant at the 650°C. Biochars at 300–450°C exhibited a more notable increase in soil DOC. At pH ≤ 5.8, Al-DOC and free Al3+ dominated in soil solution while at pH > 5.8, Al species was mainly Al-OH ions (i.e. Al(OH)2+, Al(OH)2 +, Al(OH)3, and Al(OH)4−). Biochars at 300–450°C promoted the large formation of Al-DOC while Al-OH ions dominated in 650°C-biochar treatments. Biochar can be used to ameliorate Al phytotoxicity in tropical acid soils, particularly at 300–450°C.Item Adaptive capacity and coping strategies in the face of climate change: A comparative study of communities around two protected areas in the coastal savanna and transitional zones of Ghana(Journal of Sustainable Development, 2015-01) Egyir, I.S.; Ofori, K.; Antwi, G.; Ntiamoa-Baidu, Y.Modern productivity-enhancing strategies (MPES) are considered to be some of the best adaptation options available to communities in the face of changing climatic conditions. The adaptive capacity of communities living around two protected areas (Kogyae Strict Nature Reserve and Muni-Pomadze Ramsar Site) in Ghana were assessed in relation to MPES by investigating household accessibility to human, social, natural, financial and physical capital. Information was collected from 249 and 250 respondents in Kogyae and Muni respectively. A logit model was used to find out whether adaptive capacity affected adoption of MPES. In both study areas, indigenous coping strategies such as use of simple farm tools, processing of root/tubers and grains and social grouping were practiced. The MPES practiced included application of fertilizers and other agrochemicals, use of high technology machinery and bunding in rice fields. The mean level of adaptive capacity of farm households was low in both areas; 0.30 and 0.27 in Kogyae and Muni respectively. The adoption of MPES was influenced positively by the level of human and physical capacities and farm size and location of protected area, and negatively by farmers' participation in off-farm activities. Farmers located in Kogyae were more likely to adopt productivity-enhancing strategies than their counterparts in Muni. Considering that access to the resources within the protected areas is restricted and not legally available to support livelihoods of the fringe communities, we conclude that enhancing access to both human and physical capitals is the way forward for climate change adaptation for these two communities. © 2015 by the authors.Item Administration of melatonin improves testicular blood flow, circulating hormones, and semen quality in Shiba goats(Theriogenology, 2020-01-30) Nyametease, P.; Samir, H.; Elbadawy, M.; Nagaoka, K.; Sasaki, K.; Watanabe, G.Despite the role of melatonin in the regulation of the sleep-wake cycle and seasonal-reproduction, the present study investigated, for the first time, the potential role of melatonin on testicular blood flow (TBF) in goats. Twelve sexually mature male Shiba goats were exposed to a single s.c. injection of either melatonin suspended in one ml of corn oil (melatonin group; 36 mg/goat; n ¼ 5) or one ml of corn oil (control group; n ¼ 7). Monitoring the changes in TBF was done one week before (W-1), at the time of injection (W0), and once a week for 8 weeks after injection using color-pulsed Doppler ultrasonography. Concentrations of FSH, LH, inhibin, testosterone (T), estradiol (E2), and insulin-like growth factor-1 (IGF- 1) in plasma were determined by radioimmunoassay. Melatonin and nitric oxide (NO) concentrations were measured using enzyme immunoassay kits. Moreover, semen collection and evaluation of some sperm parameters were performed once a week. Results revealed decreases (P < 0.05) in the Doppler indices (resistive index, pulsatility index) of the testicular arteries from W2 till W6 in the melatonin group. FSH, LH, and inhibin concentrations did not change between the two groups, while T, E2, IGF-1, NO, and melatonin concentrations increased (P < 0.05) in the melatonin group compared to the control. Estradiol and NO concentrations increased (P < 0.05), coinciding with decreases in the values of Doppler indices. Notable (P < 0.05) improvements in most parameters of semen quality were seen in the melatonin group. In conclusion, melatonin induced a stimulatory effect on TBF in Shiba goats and possibly, it could be a potential to improve male goats fertilityItem Adoption of crop insurance in Ghana: an application of the complementary log-log truncated Poisson double-hurdle model(Emerald Publishing Ltd, 2021) Addey, K.A.; Jatoe, J.B.D.; Kwadzo, G.T.Purpose – The aim of this paper is to identify the factors that influence rice farmers’ decisions to adopt crop insurance and premium payments (willingness to pay [WTP] amounts). The paper also demonstrates the usefulness of the complementary log-log (cloglog) truncated Poisson double-hurdle model as an alternative hurdle model. Design/methodology/approach – The study first investigated the nature of the dependent variable, which had non-normal residuals and was overdispersed. The probit truncated normal regression double-hurdle model was tried but it failed the normality and homoscedasticity tests; hence, the cloglog truncated Poisson double hurdle model was employed in the study. Findings – An estimated 61% of respondents would purchase crop insurance, despite farmers not having prior experience with this product. Amongst others, the factors that influence insurance adoption amongst rice farmers are the share of rice in total income, reliability perception of crop insurance schemes and the probability of failure to achieve target yields. The latter helps the authors to address adverse selection, a central issue to the viability of such an insurance programme. The determinants of farmers’ WTP are also identified. Research limitations/implications – Sampling was limited to farmers using irrigation and living in one region of Ghana, which may limit the study’s wider applicability. Originality/value – As far as the authors are aware, this study is the first to select the appropriate hurdle model based on established properties of the dependent variable on this topic – crop insurance decisions.Item African weaver ant-produced semiochemicals impact on foraging behaviour and parasitism by the Opiine parasitoid, Fopius arisanus on Bactrocera invadens (Diptera: Tephritidae)(Biological Control, 2014-12) Appiah, E.F.; Ekesi, S.; Afreh-Nuamah, K.; Obeng-Ofori, D.; Mohamed, S.A.The fruit fly, Bactrocera invadens is an alien invasive pest of mango in Africa. The predatory African weaver ant, Oecophylla longinoda is being promoted for managing B. invadens and classical biological control with the Opiine parasitoid, Fopius arisanus is also underway. The current study investigated interactions between these two natural enemies. Specifically we assessed whether semiochemicals deposited by the ant on leaves and fruit affected the landing behavior of F. arisanus, its patch residence time and subsequent parasitism rates. Results showed that significantly more F. arisanus landed on 'ant-unexposed' leaves and fruits (leaves: 3.8 ± 0.5-7.7 ± 0.8; fruits: 4.1 ± 0.1-8.1 ± 1.2) compared with 'ant-exposed' leaves and fruits (leaves: 0.4 ± 0.1-2.5 ± 0.3; fruits: 0.2 ± 0.1-2.8 ± 0.7) from mango, citrus, guava and avocado. Parasitoid patch residence times were significantly longer on 'ant-unexposed' mango fruits (654.2 ± 28.4. s-1034.2 ± 112.6. s) compared to 'ant-exposed' fruits (75.2 ± 18.4. s-144.8 ± 42. s) regardless of whether eggs of B. invadens were present. In terms of percent parasitism, F. arisanus achieved significantly higher parasitism rates in B. invadens from 'ant-unexposed' mango fruits (72.8 ± 3.8) compared with 'ant-exposed' fruits (18.2 ± 1.8). Regression analysis showed a significant inverse relationship between the duration of exposure of mango fruits to ant-produced semiochemicals and the number of F. arisanus adults landing on fruits and percent parasitism. In field cages, 32% parasitism of B. invadens was achieved in mango fruits on trees without ants and 11% in mango fruits on ant-infested trees. These results suggest the potential for biotic interference between the two natural enemies if they are recommended for use within the same ecosystem. © 2014 Elsevier Inc.Item Age, genotype and sex effects on growth performance of local chickens kept under improved management in Ghana(Tropical Animal Health and Production, 2012-01) Osei-Amponsah, R.; Kayang, B.B.; Naazie, A.Characterisation of animal genetic resources has been recognised globally as an important step towards their sustainable use. Body weight data of local chickens (213 forest and 160 savannah chickens) and 183 French free-ranging SASSO T44 chickens kept under improved management were collected from hatch to 40 weeks of age and analysed to determine the effects of age, genotype and sex on their growth performance. At all ages, SASSO T44 chickens had significantly (P < 0.05) higher weights (2.6-3.2 kg at 28 weeks) than the local chickens (1.2-1.7 kg at 28 weeks). The rate of growth at the earlier ages in the local genotypes (5.57-7.80 g/day) was lower than the range of 13.81-15.42 in SASSO T44 chickens. Except at hatch, savannah chickens were significantly heavier (P < 0.05) than the forest chickens at all ages. Male chickens had significantly (P < 0.05) superior growth rates than females across all genotypes except from the 20th to the 28th week. Growth trends in both sexes depicted linear increase in body weights; however, the rate of increase in body weights was higher in males as compared to females, thus showing clear sexual dimorphism. There were no significant (P > 0.05) differences in the growth rates of SASSO T44 chickens and local genotypes at the later ages (20-28 weeks). Local chickens from the savannah zone had better growth rate than forest chickens. The significant effect of ecozone on the growth potential of local chickens is an indication that their productive potential could be improved through interventions in the environment such as provision of feed and some veterinary care. © 2011 Springer Science+Business Media B.V.Item Age-related changes in the gross anatomy of the reproductive organs, and associated steroid hormone profiles in male and female guinea fowls (Numida meleagris)(Veterinary and Animal Science, 2018-12) Abdul-Rahman, I.I.; Jeffcoate, I.; Obese, F.Y.Owing to the paucity of information on the reproductive biology of guinea fowls, a study involving a total of 132 birds was conducted, and this documented the developmental changes in the gross anatomy of the reproductive organs of males and females from hatching until 32 weeks of age (WOA), and associated steroid hormone changes. Testicular anatomical biometric traits increased significantly (p < 0.0001) from 8 WOA, and stabilised between 16 and 20 WOA, while peripheral testosterone concentration peaked at 20 WOA. Correlations among all testicular biometric characteristics were strong and positive (p < 0.0001). Similarly peripheral testosterone concentrations strongly (p < 0.01) and positively correlated with all the testicular anatomical biometric traits. In the female guinea fowl, the ovary and oviduct were discernible and measurable at hatching. Significant (p < 0.0001) increases were seen in ovarian and relative ovarian weights, and oviducal weights and lengths between 24 and 28 WOA. Plasma 17β-oestradiol decreased gradually to a very minimum at 16 WOA, and then began to increase gradually until 28 WOA when it plateaued. Peripheral progesterone concentrations on the other hand increased gradually from 4 WOA and peaked at 12 WOA, and then fluctuated considerably thereafter. Correlations among ovarian/oviducal anatomical parameters were strong (p < 0.0001) and positive. Similarly, peripheral oestradiol concentrations strongly (p < 0.0001) and positively correlated with all ovarian/oviducal anatomical parameters. Testicular anatomical biometric traits stabilised between 16 and 20 WOA, coinciding with peak peripheral testosterone concentrations, while ovarian/oviducal parameters recorded huge increases between 24 and 28 WOA, and may be under the influence of oestradiol.Item Agency problem and hedging in agri-food chains: model and application(Journal of Marketing Channels, 2009) Kuwornu, J.K.M.; Erno Kuiper, W.; Pennings, J.M.E.The last four decades have seen the transformation of food supply chains from being supply-driven to becoming much more closely integrated with consumer demand. With this development, the transaction mechanism in food marketing channels has changed from open market mechanism to coordination through the use of contract-supply arrangements between farmers and food processors and retailers. In this paper, we assess the interaction of marketing channel members through the use of contracts and its impact on incentives, coordination costs, risk aversion, risk allocation and risk management strategies. For this purpose we specify a three-stage principal-agent supply chain model involving producers, wholesalers, retailers and a futures market. We compare the situation with and without futures market. The empirical results regarding the Dutch ware potato marketing channel during 1971-2003 reveal that as a result of increases in incentives to producers and wholesalers, the coordination costs of the marketing channel decreased significantly, both with and without futures trade. The coordination costs of the marketing channel in the case with a futures market appear to be lower than without futures, demonstrating the informational (that is, price discovery) role of futures markets.Item Agricultural credit rationing in Ghana: What do formal lenders look for?(Agricultural Finance Review, 2014-08) Awunyo-Vitor, D.; Al-Hassan, R.M; Egyir, I.; Sarpong, D.BPurpose – The purpose of this paper is to investigate the determinants of agricultural credit rationing by formal lenders in Ghana. Design/methodology/approach – This study employed descriptive statistics, analysis of variance (ANOVA) and Heckman’s two-stage regression model to identify types of rationing faced by farmers and investigate factors that influence agricultural credit rationing by formal financial institutions. Data used in this study are gathered through a survey of 595 farmers in seven districts within Brong Ahafo Region of Ghana. Findings – The result reveals that farmers face three types of rationing. Evidence from the Heckman two-stage models shows that engagement in off farm income generating activities, increase in farm size, positive balances on accounts and commercial orientation of the farmers has the potential to reduce rationing of credit applicants by formal lenders. Practical implications – The results provide information on the factors that need to be considered as important in an attempt to reduce agricultural credit rationing by formal lenders. Originality/value – The value of this study is that farmers would use the results of this study to improve access to required amount of agricultural credit from formal financial institutions. The information would also benefit stakeholders in the agricultural sector, particularly youth in agriculture program organized by Ministry of Food and Agriculture in Ghana as how to improve access to credit and reduce rationing of program participants by formal financial institutions. © Emerald Group Publishing Limited.Item Agricultural insurance access and acceptability: examining the case of smallholder farmers in Ghana(Agriculture & Food Security, 2021) Ankrah, D.A.Background: Weather-related risks thwart agricultural productivity gains especially in the face of climate change. Agricultural insurance serves as a reliable risk mitigation instrument for coping with climate-related hazards. This notwithstanding, agricultural insurance penetration among smallholder farmers in the global south remains low. This study investigated the access and acceptability of agricultural insurance among smallholder food crop farmers in Ghana. Method: The study employed a mixed-methods approach involving both quantitative and qualitative approaches. The study was carried out in the Northern, Volta and Western regions involving 7 communities in 5 districts. A total of 200 farmers were sampled through a multi-stage purposive sampling and interviewed. A cross-sectional survey involved 100 respondents under the quantitative approach whilst the qualitative study engaged additional 100 farmers. Results: The results show that smallholder farmers’ access and acceptability of agricultural insurance is low (14%) and scarce but ironically considered useful by many (90%) as an effective tool to deal with agricultural risks. Inadequate knowledge about agricultural insurance products constituted the most stated reason (64%) for the scarce adoption rate, followed (23%) by the unavailability of insurance products in areas needed but absent. A few (5%) reported insurance to be expensive. Acceptability and accessibility of agricultural insurance are further influenced by gender, educational level, low knowledge, information asymmetry and wrong perception concerning agricultural insurance products. Sense of security and reduced impact of climate variabilities constituted important benefits guaranteed by agricultural insurance. Conclusions: Agricultural insurance access and acceptability is constrained by limited knowledge of agricultural insurance products. It is recommended that more insurance companies be incentivized to augment already existing efforts by Ghana Agricultural Insurance Pool (GAIP) to enroll more smallholder farmers. The government can consider bundling existing insurance products with credit or inputs under the Planting for Food and Jobs Programme (PFJ) to improve uptake and accessibility of agricultural insurance.Item Agricultural insurance access and acceptability: examining the case of smallholder farmers in Ghana(Agriculture & Food Security, 2021) Ankrah, D.A.; Kwapong, N.A.; Eghan, D.; Adarkwah, F.; Boateng‑Gyambiby, D.Background: Weather-related risks thwart agricultural productivity gains especially in the face of climate change.

Relying on panel data covering thirty-one African countries obtained from the World Bank World Development Indicators and FAOSTAT databases, we answered the question of whether agricultural production (proxied by livestock production, fertilizer consumption, and land under cereal cultiva tion), the use of renewable energy, and FDI increase or reduce carbon emissions. Using the panel autoregressive distributed lag model for analysis, our results show that net FDI, fertilizer consump tion, livestock production significantly increased carbon emissions, both in the short run and long run. Meanwhile, renewable energy use consumption significantly decreased carbon emissions, both in the short run and long run. Specifically, a 1% increase in net FDI increased total carbon emissions by 0.003% in the short run and by 0.01% in the long run. Renewable energy consumption significantly decreased carbon emissions, both in the short run and long run. A 1% increase in renewable energy consumption decreased total carbon emissions by 0.16% in the short run and by 0.22% in the long run. Additionally, fertilizer consumption and livestock production significantly increased carbon emissions in the short run and long run. A 1% increase in fertilizer consumption increased total carbon emissions by 0.01% in the short run and by 0.04% in the long run, while a 1% increase in livestock production increased total carbon emissions by 0.20% in the short run and by 0.56% in the long run. The findings call for investment in renewable energy technologies and consumption while advocating for large-scale uptake of climate-smart agriculture, and environmentally friendly targeted foreign direct investments on the continent.Item Agro-Industrial Waste Biochar Abated Nitrogen Leaching from Tropical Sandy Soils and Boosted Dry Matter Accumulation in Maize(Journal of Carbon Research, 2023) Egyir, M.; Lawson, I.Y.D.; Dodor, D.E.; Luyima, D.This study was conducted to assess the effects of amending tropical sandy soils with biochar derived from agro-industrial wastes on the leaching and utilization of nitrogen (N) by maize. The experiment was conducted in pots in a greenhouse with two sandy soil types and two different biochars. The biochars used in this experiment were preselected in a preliminary column experiment that assessed the N retention capacities of the different biochars and those that exhibited the best retention capacities chosen for experimentation. The biochars evaluated included saw dust, rice husk and corncob pyrolyzed at 500 ◦C and the results from the column leaching experiment showed that sawdust biochar had superior retention capacities for both NO3 − and NH4 + , followed by rice husk biochar. The pot experiment utilized sawdust and rice husk biochars applied at rates of 0, 20 and 40 t/ha to the soil treated with different N sources including cow dung and ammonium sulfate and growing maize on the amendments for two seasons with each season lasting for five weeks. The soils were leached on the 14th and 28th days after planting to determine the amount of leachable N. Biochar amendments reduced the leaching of NO3 −N and NH4 +N with no significant differences observed between biochar types, but between soil types. The abatement of leaching by biochar amendments consequently enhanced N uptake by maize and dry matter production and thus, agro-industrial waste biochar amendment is recommended for reducing leaching in tropical sandy soils.
