- ItemDiagnosing Soil Degradation and Fertilizer Use Relationship for Sustainable Cotton Production in Benin(2018-01-05) Barthelemy G. HonfogaIn Benin and many other cotton-producing countries of West Africa, unsustainable natural resource management is hindering agricultural growth, food security, and poverty reduction. This study addressed the sustainability of fertilizerbased soil fertility management practices in Benin. It diagnosed the relationship between differential soil degradation status over space and fertilizer use in cotton production systems. Referring to sound land use principles, it found that present fertilizer use practices overlook the spatial differences in soil fertility status in exportoriented cotton production systems. Considering more relevant short-run fertilizer needs based on desirable fertilizer doses, the potentials for sustainable fertilizer use were then assessed considering the likelihood of change towards best practices of integrated soil fertility management. More rational fertilizer use practices will be critical in the future to inducing higher cotton yields while preserving the environment. Adjusting current fertilizer recommendations to site-specific soil conditions is urgently required to enhance the sustainability of cotton production systems in Benin. Fertilizer policies will need to rely on updated information on soil and land use dynamics, and be innovative enough to induce a steady increase in agricultural productivity and improved net incomes cotton growers.
- ItemEnvironmental Degradation Effect on Agricultural Development: An Aggregate and a Sectoral Evidence of Carbon Dioxide Emissions from Ghana(2022-02) Paul Adjei Kwakwa; Hamdiyah Alhassan; William AdzawlaPurpose – Quality environment is argued to be essential for ensuring food security. The effect of environmental degradation on agriculture has thus gained the attention of researchers. However, the analyses of aggregate and sectoral effect of carbon dioxide emissions on agricultural development are limited in the literature. Consequently, this study examines the effect of aggregate and sectoral carbon emissions on Ghana’s agricultural development. Design/methodology/approach – Time-series data from 1971 to 2017 are employed for the study. Regression analysis and a variance decomposition analysis are employed in the study. Findings – The results show that the country’s agricultural development is negatively affected by aggregate carbon emission while financial development, labour and capital increases agricultural development. Further, industrial development and emissions from transport sector, industrial sector and other sectors adversely affect Ghana’s agriculture development. The contribution of carbon emission together with other explanatory variables to the changes in agricultural development generally increases over the period. Originality/value – This study analyses the aggregate and sectoral carbon dioxide emission effect on Ghana’s agricultural development.
