Abstract
Despite the importance of crop diversification in enhancing household income and food security, significant knowledge gaps remain in terms of the precursors and actual impacts of diversified food-cash crop systems. Thus, we assessed the determinants of food-cash crop diversification, and its impacts on the income and food security of farmers using survey data from 408 randomly-selected households in the Forest-Savannah Transition Zone of Ghana. The study employs the multinomial logistic model (MNL) to examine farm households’ decision to practice food-cash crop diversification, while the inverse probability weighted regression adjustment (IPWRA) was performed to determine the impact of the diversification on food security and household income. Diversification of cash and food crops impacted positively on household annual crop income and on food security, and these positive impacts further increased as the diversity of tree cash cropping increased, with the addition of cocoa and/or cashew. Our findings emphasise the importance of income from tree cash crops, and complementarities between cash crops and food crop production in explaining the food security merits of diversified food-cash crop systems. Overall, a food-crop-farmers’ decision to diversify into cocoa and cashew in Ghana was significantly predicted by farming experience of the household head, and farm characteristics of the household (fallow land availability, land ownership and livestock ownership), as well as economic (annual crop income and access to off-farm income) and institutional (access to extension) factors. These results imply that enhancing farmers’ access to financial and technical support services and promoting livestock farming could encourage the adoption of diversified cropping systems. However, since land ownership rights in sub-Saharan Africa are oftentimes unclear, contested or poorly enforced, pro-poor and equitable land tenure reforms would be indispensable in promoting diversification into tree cash crops by subsistence farm households.
期刊介绍：
Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches.
Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet.
From this perspective, the journal covers the following areas:
Global food needs: the mismatch between population and the ability to provide adequate nutrition
Global food potential and global food production
Natural constraints to satisfying global food needs:
§ Climate, climate variability, and climate change
§ Desertification and flooding
§ Natural disasters
§ Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production
§ Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production
The sociological contexts of food production, access, quality, and consumption.
Nutrition, food quality and food safety.
Socio-political factors that impinge on the ability to satisfy global food needs:
§ Land, agricultural and food policy
§ International relations and trade
§ Access to food
§ Financial policy
§ Wars and ethnic unrest
Research policies and priorities to ensure food security in its various dimensions.
