The choice of a suitable site for any aquaculture practice is a critical decision to make since it has a large impact on the economic profitability of the venture, considering the fact that location defines the amount of capital needed, production costs, yield and access to market. The limited public and private sector support for small-scale aquaculture can be optimized if farms are zoned into areas with relatively similar performance and needs. Considering the high rate at which aquaculture is increasing globally and its consequent impact on the environment, it is projected that improvements will be made in the practices employed in aquaculture. As these improvements are made, there is the need for the review of the location of aquaculture infrastructure and services in order to increase the productivity of the sector. Also, aquaculture statistics such as location of farms and production estimates are fundamental to policy making and development planning at both national and global levels. Aquaculture statistics are however chronically scanty or unreliable in developing countries such as Ghana. Thus, the goal of this study was to show the relative suitability of areas in Ghana for aquaculture and identify the key variables to be considered in the development (including improvement of existing farms) of the aquaculture sector of the country. I used satellite imagery and GIS data in combination with field observations and questionnaires, to develop a map of the feasibility of pond aquaculture in Ghana and provide a reliable estimate of the number of ponds, their areas, productivity and aggregate production in the country. The main factors that have influenced the current distribution of pond aquaculture in Ghana are population density (indicating the availability of markets, input and labor) and proximity to stream and road networks. My results show a gross underestimation of the number of fish ponds in the country and smaller sizes of ponds than existing records suggest. The average water depth of ponds in Ghana is only half of the recommended depth which explained over 80% of the variation in productivity among farms. I estimated the contribution of ponds to domestic fish production to be two to three times what has been previously reported, but still well below the potential. The results of this study will be vital to current national and international efforts to improve aquaculture enterprises in Ghana. / Master of Science

This dissertation focuses on identifying the poor in Sub-Saharan Africa (SSA) and the potential of social assistance programs to address their condition. Each essay is related to one particular key step of the poverty alleviation agenda: poverty definition and measurement in Zimbabwe; targeting poor households in Cameroon; and impact evaluation of anti-poverty interventions in Niger. The first essay explores changes in poverty across multiple dimensions in a period of dramatic economic crisis and recovery in Zimbabwe. The essay analyzes changes in household well-being between 2001, 2007 and 2011/12, using an Alkire-Foster multidimensional poverty index. Results indicate a large increase in multidimensional poverty across between 2001 and 2007, followed by a (smaller) decrease in poverty between 2007 and 2011/12 (recovery period after the hyperinflation peak in 2008). However, decomposition of the index shows significantly different trends in poverty dimensions over time, as for instance health related dimensions continued to deteriorate after 2007. The second essay contributes to the policy debate on targeting by studying the ex-post efficiency of two targeting mechanisms employed in a cash transfer project in rural Cameroon: Proxy Means Testing (PMT) and community targeting. Results show a poor performance of community targeting in selecting households with low per capita consumption, compared to PMT targeting—whose errors remain high nonetheless. Communities tend to select small, isolated households with low physical and human capital, regardless of their actual consumption level, but produce variable outcomes. Overall results suggest that a higher coverage contributes to reducing targeting errors, and that better guidance should be provided to communities if the policy objective is to select low per capita consumption individuals. The third essay investigate whether cash transfers induce investments in assets and productive activities that survive the termination of program payments using data from an unconditional cash transfer project in Niger 18 months after its termination. Based on quasi-experimental methods, results indicate that local saving/credit systems (tontines) participation and livestock ownership significantly increased among project participants. There is also evidence of improvement in private assets, micro-enterprises and agriculture. The findings imply that cash transfer programs can have long-term sustainable impacts in rural SSA. / Ph.

Yes / Extant research has established that environmental sustainability orientation (ESO) has a positive influence on performance outcomes. Nevertheless, several contingencies tend to affect the strength of this relationship. In this study, we draw on natural resource-based theory to introduce competitive strategies as moderators in the ESO-performance nexus. Using time-lagged data obtained from 269 firms in Ghana, this study finds that firms pursuing the differentiation strategy can positively boost performance outcomes with ESO than without differentiation strategy. We also find that firms can use the low-cost or the integrated strategy to get higher impact on performance with ESO respectively. Based on the results, firms in Ghana do not need differentiation strategy in order to boost the effect of ESO on financial performance. Theoretical and practical implications are discussed.

Yes / While previous research has emphasized the role of stakeholder pressures, firm‐specific factors, as well as CEO characteristics as important drivers of corporate social responsibility (CSR) implementation, our understanding of how political connections impact small and medium‐sized enterprises' (SMEs') CSR implementation expenditure is quite limited. In this study, we contribute to filling this gap by investigating the effects of political connections and CSR expenditure and explain the conditions that impact this relationship. Using data from 473 SMEs in Ghana, we find that political connections negatively influence CSR implementation expenditure. However, the negative effect is weakened when a firms' reputation and competitive CSR implementation pressures are high. Implications for theory and practice are discussed. / University of Economics Ho Chi Minh City, Vietnam

Yes / Despite the burgeoning interests in the environmental strategy, there is a limited understanding of how human resource slack drives sustainable innovation and environmental performance. This paper contributes to filling this gap by examining the effect of human resource slack on sustainable innovation and its impact on environmental performance. Besides, this paper investigates the contingent effects of intangible resource advantage on this relationship. The hypotheses are tested using data from 301 small and medium‐sized enterprises in Ghana. The results suggest that human resource slack positively relates to sustainable innovation and this relationship is moderated by intangible resource advantage. Also, we find that sustainable innovation mediates the relationship between human resource slack and environmental performance. The insights from our paper provide a nuanced understanding of the relationships among human resource lack, sustainable innovation, and environmental performance. Implications for theory and practices are discussed. / University of Economics Ho Chi Minh City, Vietnam
