A socio‐economic assessment of cowpea diversity on the Ghanaian market: implications for breeding

Given the importance of cowpea [Vignaunguiculata(L)Walp] in fighting malnutrition and poverty, a socio‐economic assessment of cowpea diversity found on the Ghanaian market was conducted. The objective was to investigate emerging consumer preference for cowpea and make recommendations for the development of tailor‐made varieties. Forty‐seven cowpea accessions were collected from traders interviewed for morphological characterization to ascertain the degree of diversity. Data was subjected to Hierarchical Cluster Analysis using Genstat Discovery Edition 3 software and variations among the cowpea varieties based on the selected seed traits established. Cowpea varieties found on the markets were broadly categorized into foreign and local varieties and usually named after their sources. Foreign Cowpea varieties were very popular on the markets surveyed as reflected in the per cent distribution of respondents by cowpea varieties sold; Niger (52%), Burkina Faso (50%), Togo (46%), Lagos (36%) and Ghana (18–21%). At the trader level, the order of preference for cowpea characteristics was cleanliness (stone free and no dirt), colour (white seed colour), easy to cook, taste, size, less weevil damage, dryness and place of origin ranked in decreasing order of importance. At the consumer level, cleanliness that was also tied to the extent of weevil damage was ranked most important. This was followed by seed colour (preferable white), short cooking time, size and taste. From the sociological perspective, concerns are raised on the impact of past cowpea breeding activities giving the level of competitiveness and market performance of locally improved varieties observed. Recommendation is made for traders and consumers to be considered as relevant actors in all the stages of crop improvement and breeding activities. This is crucial for enhanced small‐holder farmer market access and strengthened food networks in rural economies.     

The good in evil: a discourse analysis of the galamsey industry in Ghana

Galamsey, a low-tech, labour-intensive, small-scale mining activity in Ghana, has recently come under intense criticism and state policing despite being an important livelihood source. Based on empirical research, this paper uses discourse analysis to re-examine galamsey politics in Ghana, focusing on why people are engaged in galamsey despite attempts to curtail it. Findings suggest that for most individuals and communities, poverty, displacement from agricultural lands and unemployment explain their initial entry into the industry. However, the legal, regulatory and policing regimes, together with complex, ambivalent relationships between government, large-scale mining companies, traditional authorities and galamsey operators, all help to perpetuate galamsey. These findings provide a counter-narrative to the dominant discourse of opportunism and demonisation which often characterises public discussions on Ghana’s galamsey industry. Rather than the combative approach taken by the state towards the galamsey phenomenon, urgent legislative and policy reforms are needed in order to streamline the licensing regime and address the drivers of galamsey.     

Tax Elasticities and the Impact of Discretionary Tax Measures on Government Revenue in Papua New Guinea, 1975–92

This paper evaluates tax elasticities and the impact of discretionary tax measures on government revenue in Papua New Guinea (PNG) using a dynamic macroeconometric model of taxation which captures the interaction between GDP, individual tax systems and individual tax revenues and bases. Our findings show that economic growth and discretionary tax changes have both been effective in mobilizing additional tax revenue. However, the responsiveness of the individual tax system reflected base-to-GDP elasticity except personal income tax whose elasticity reflected increased tax rates.     

A review of the economic impact of malaria in agricultural development

This paper surveys the linkages between malaria and agriculture, focusing on the economic impacts of the disease. We adopt Negin's (2005) conceptual framework to examine the potential impacts of malaria in the agricultural sector, including both direct and indirect impacts. In addition to health care costs, malaria causes loss of agricultural labor and slows adoption of improved practices in agriculture. Furthermore, some agricultural practices and development interventions are known to facilitate the spread of malaria, exacerbating its impacts. Given the importance of both agriculture and malaria in developing countries, especially in Africa, the interaction between them could be a significant factor in economic growth. The review identifies gaps in past research on this topic. A better understanding of malaria's impact on agricultural productivity, coupled with efforts to strengthen capacity to deal with malaria, would enhance policies and programs aimed at combating malaria and curbing its impacts on agricultural productivity.
