Item Charting sustainable waters: Governance challenges and opportunities for fisheries and coastal beach resources in a West African country(Marine Policy, 2024) Takyi,R.; Nunoo,F.K.E.; Mahrad,B.E.; Addo,C.; Essandoh,J.Marine fisheries and beaches (i.e., backshore, foreshore and shoreface) are essential for providing ecosystem services globally, with coastal states being at the forefront of this benefit. Consequently, several policies, legislations, and governance processes must be formulated to ensure their sustainable use due to the impact of anthropogenic and natural pressures. This study aims to analyse the legal and institutional frameworks for the management of marine fisheries and beach resources (such as flora (coconut), fauna (ghost crabs), dunes, and rocky components) under key international laws and conventions, using Ghana as a case study. The study identifies the strengths, weaknesses, opportunities, and threats (SWOT) within resource management, as well as their impact on the country’s progress in the attainment of the Sustainable Development Goals (SDGs) and Africa Union Agenda 2063. Data was collected through interviews with fishers, coastal residents, and other relevant stakeholders, as well as a review of secondary data. The results unveil a distinctive contrast in the regulatory landscape between fisheries and beach resources. While numerous policies have been formulated to ensure the sustainable management of fisheries, the same level of attention and commitment has not been extended to beach resources. The SWOT analysis revealed that some of the strengths in the governance of marine fisheries and beach resources rest on the availability of institutions and laws. The weakness lies in inadequate enforcement and data gathering and analyses to inform decision making. This study provides as an illuminating exploration into the legal and institutional underpinnings of marine fisheries and beach resource management in Ghana, shedding light on the critical junctures where improvements are needed.Item Who is marginalized in energy justice? Amplifying community leader perspectives of energy transitions in Ghana(Energy Research & Social Science, 2021) Baker, E.; Atarah, S.A.; Afful-Dadzie, A.; et al.There is a divide in energy access studies, between technologically-focused modeling papers in engineering and economics, and energy justice frameworks and principles grounded in social sciences. Quantitative computational models are necessary when analyzing energy, and more specifically electricity, systems, as they are technologically complex systems that can diverge from intuitive patterns. To assure energy justice, these models must be reflective of, and informative to, a wide range of stakeholders, including households and communities alongside utilities, governments, and others. Yet, moving from a qualitative understanding of preferences to quantitative modeling is challenging. In this perspective piece, we pilot the use of the value-focused thinking framework to inform stakeholder engagement. The result is a strategic objective hierarchy that highlights the tradeoffs and the social, economic, and technological factors that need to be measured in models. We apply the process in Ghana, using a survey, stakeholder workshops, and follow-up interviews to uncover key tradeoffs and stakeholder-derived objectives. We discuss three key areas that have been rarely, if ever, well-represented in energy models: (1) the relationship between the dynamics of electricity end-use and the technology and economic structure of the system; (2) explicit tradeoffs between electricity access, cost, and reliability as defined by stakeholders; and (3) the definition of new objectives, such as minimizing hazards related to theft. We conclude that this model of engagement provides an opportunity to tie together rigorous qualitative analysis and stakeholder engagement with crucial quantitative models of the electricity system.Item Measuring sustainability of conservation and conventional practices in maize production in Ghana(Journal of Agriculture and Environment for International Development, 2020) Boimah, M.; Mensah-Bonsu, A.; Osei-Asare, Y.; Sarpong, D.B.Scientists and researchers worldwide have recommended Conservation Agriculture has the potential to promote sustainability in agriculture. This paper attempts to measure and compare the economic, social, and environmental sustainability of both conservation and conventional practices used for maize production in the northern region of Ghana employing the Multi-Attribute Value Theory (MAVT) approach. Based on the three pillars of sustainability (economic, social, and environmental), adopters of minimum tillage practice (scoring 0.5, 0.6, 0.82), and the combined adoption of minimum tillage and integrated organic-inorganic fertilizer application (scoring 0.53, 0.5, 0.88) emerged as sustainable practices. Despite these scores, the z-test of difference in means of the conservation practices and conventional ones were all insignificant, indicating that the conservation practices in use were not different from the conventional ones in terms of their contribution to sustainable maize production. Technical assistance and training that aids in ensuring the appropriate application of conservation practices should be ensured if the goal of sustainability is to be realized.Item Decolonizing posthumanism: Indigenous material agency in generative STEM(British Journal of Educational Technology, 2020) Eglash, R.; Hammond-Sowah, D.; Bennett, A.; et.alThis paper describes a decolonial perspective on material agency in the context of STEM education and application. Using the framework of generative STEM, we engaged in case studies with African, African American, South American, and Native American educational communities. This research shows that understanding material agency based on Indigenous knowledge systems can open a rich source of research and education content. Using a suite of simulations and culturally Situated Design Tools, we apply this body of research to the classroom. One important theoretical conclusion is the contrast to a “content agnostic” position. A generative framework instead offers a robust blend of user agency and instructional guidance. The outcomes indicate statistically significant and notable improvement in STEM skills and interests. We conclude with a contrast to the quantum epistemology approach to posthumanism. We show that the Indigenous material agency framework in generative STEM is a better fit for decolonial aspirations and that it offers a more transformative vision for the potential role of STEM in transitioning from an extractive to a generative economy.Item Knowledge and Practice of Iodized Salt and Iodine Deficiency Disorders among Men in Nungua, Ghana(Universal Journal of Public Health, 2020-04-19) Setorglo, J.; Agyei, B.A.; Steiner-Asiedu, M.; et.alBackground: Iodine Deficiency Disorders (IDDs) continues to be a problem in Ghana after several years of salt fortification with iodine. Sustainable IDD prevention requires a well-informed population willing to use iodized salt. This study determined men's knowledge levels on iodized salt, and IDDs iodized salt usage. Methods: This was a cross-sectional study involving 400 men (18 years and above) sampled conveniently at Nungua in the Ledzokuku Krowor Municipality of the Greater Accra Region, Ghana. Data on socio-demographics, knowledge, use of iodized salt, and IDDs were collected. We computed descriptive statistics for socio-demographic data, knowledge of iodized salt, usage of iodized salt, and knowledge of IDDs. We grouped scores for knowledge of iodized salt into poor and good. Scores for knowledge of IDDs were split into tertiles and labeled as low, moderate, and high. Chi-Square (χ2 ) test and multinomial logistic regression were performed to determine the association between socio-demographic characteristics, good knowledge of iodized salt, and high knowledge about IDDs. Results: The majority of respondents (37.5%) were aged between 26 and 41 years. About 97.8% have heard about iodized salt and 69.3% first heard about iodized salt through the media. About 70.5% used iodized salt in cooking and 76.8 % of the respondents would encourage women to use salt in cooking. When the knowledge level was split into two groups, the higher proportion (266 out of 400) had poor knowledge of iodized salt and in tertiles, the majority (184 of 400) had low knowledge on IDDs. There were statistically significant differences between age, marital status educational level, and knowledge of IDDs all at P< 0.001. Those with Junior High School education had 54% less chance, OR= 0.465; 95% CI: (0.244, 0.884) of obtaining a good knowledge of iodized salt compared with those with a University education. Conclusions: Knowledge of iodized salt was low, and knowledge of IDDs was low among the men. There is a difference in the level of knowledge of IDDs among the socio-economic groups but not knowledge on iodized salt and its use. The more educated the men are, the more likely they are to use iodized salt.Item The Productivity and Management of Ghanaian Soils(Soil Productivity Management in Ghana, 2023) Adiku, S.G.K.Over decades we have longed for a book that related the scientific principles of soils to the Ghanaian context. Most of the textbooks were written by foreign authors with little or no data on soils from Ghana. Our reading and understanding about soils were abstract. This book fills this great vacuum with data from the soils in Ghana. The book will enhance the capacity in solving the peculiar problems of soils in our ecological zones. The book takes the reader not only through the knowledge of soils but also the related edaphic properties which directly or indirectly impact soil productivityItem Genetic Improvement for Development of a Climate Resilient Food Legume Crops: Relevance of Cowpea Breeding Approach in Improvement of Food Legume Crops for Future(CRC Press, 2023) Ofori, K.; Ngalamu, T.; Galla, J.O.; et al.ABSTRACT Global population increment coupled with the adverse effects of climate change pose horrendous possibilities for food shortage and hunger. Nevertheless, climate change embedded in several biotic and abiotic stresses affects food crops' productivity, despite breeding accomplishments. Consequently, there is urgent need for mapping out sustainable and environmentally friendly food crops as well as their efficient and appropriate improvement and production systems. This will enable genetic improvement for climate resilient, high-yielding, and nutritionally valuable food crops. Food legume crops, which represent the most valuable food source globally after cereals, are ideal for meeting the global food demand; thus, improving their productivity becomes crucial. Conversely, understanding and documenting limitations of food legume yield is a step toward a defined breeding goal. Having in-depth knowledge about the genetics of drought and heat, and deployment of molecular platforms, will enhance prospects of developing food legume varieties with improved agronomic traits. This accomplishment will be reflected in the output of any programmed and systematic improvement programs: development and release of high-yielding and early maturing food legume varieties that are tolerant and resistant to biotic and abiotic stresses. Hence, this chapter will constitute a repository for legume breeders interested in developing climate-resilient food legume varieties capable of adapting to marginal environments and giving appreciable yield in the face of climatic stressors: drought and heat stress. It could be concluded that co-occurrence of drought and heat stress during both vegetative and reproductive developmental phases of food legume crops would lead to impeded tissue development, loss of organelle functions, production of non-viable pollen, abortion of ovaries, and oxidative stress in the leaves. These will result in failure to fertilize and poor quality and quantity of assimilates produced and stored. Thus, the key to improvement for climate resilience is better understanding of pathways associated with yield, resistance, and tolerance to biotic and abiotic stresses.
