Land-use changes have dramatically transformed tropical landscapes. We describe an ecological-economic land-use change model as an integrated, exploratory tool used to analyze how tropical land-use change affects ecological and socio-economic functions. The model analysis seeks to determine what kind of landscape mosaic can improve the ensemble of ecosystem functioning, biodiversity, and economic benefit based on the synergies and trade-offs that we have to account for.
This paper addresses four questions: · What lessons can be drawn from the "rise and decline" of NARS in Africa? · What can African research managers learn from some of the successful reforms of NARS in Asia and Latin America over the past 10 to 15 years? · What are the major challenges facing the NARS in the ASARECA region in the coming 10-20 years? · What are the critical reforms and the incentives needed to develop pluralistic, accountable, productive and financially self-sustaining NARS in AFRICA?
Postharvest loss exacerbates the food insecurity and welfare loss of farming households in developing countries. This paper analyses the effect of improved storage, a climate-smart crop management technology, on household food and nutrition security, market participation and welfare using nationally representative data from Ethiopia. Endogenous switching regression models are employed to control for selection bias and unobserved heterogeneity.
This paper assesses the relationships between women’s dietary diversity and various indicators of agricultural biodiversity in farms of the Hauts-Bassins, a cotton-growing region in rural western Burkina Faso. A sample of 579 farms representative of the region was surveyed at three different periods of the year. Using a qualitative 24-h dietary recall, we computed a women’s dietary diversity score (WDDS-10) based on ten food groups.
This document presents a proposed methodology for public expenditure review and analysis for climate change adaptation and mitigation in the agriculture sector (PERCC) and its application to a case study of Kenya. It starts by explaining the basic methodological concepts, classification and labelling of public expenditures that allow for calculating spending in agriculture related to climate change adaptation and mitigation.
Rising demand for agricultural commodities coupled with population growth, climate change, declining soil fertility, environmental degradation and rural poverty in the developing world call for strategies to sustainably intensify agricultural production. Sustainable intensification refers to increasing production from the same area of land while reducing its negative environmental consequences.
We examine the impact of ambiguous and contested land rights oninvestment and productivity in agriculture in Akwapim, Ghana. Weshow that individuals who hold powerful positions in a local politicalhierarchy have more secure tenure rights and that as a consequencethey invest more in land fertility and have substantially higher output.The intensity of investments on different plots cultivated by a givenindividual corresponds to that individual’s security of tenure overthose specific plots and, in turn, to the individual’s position in thepolitical hierarchy relevant to those specific plot
Various indications that research and development efforts are escalating in developing countries indicate the slight shift of such countries from just being end markets to being developers. The aggregate adoption of biotech crops in developing countries is clearly approaching that in developed countries. The next generation biotech crops with superior traits, with improved properties and quality traits will likely be created and deployed in developing countries, particularly in Asia, where half of the world’s population dwells.
Recent studies in the literature examining impact of government seed price intervention on adoption of Bt cotton get different results depending on the specifics of the situation analyzed. According to one study, reduction in seed prices enables farmers to buy seeds at lower prices and this can result in surge of area sown under Bt cotton. The other view holds that seed price interventions have little impact on the adoption rates rather these interventions may adversely affect firms’ incentives to innovate. Which of the two views characterize adoption of Bt cotton in India?
Given its superior importance of digital agricultural solutions to overcome challenges in agricultural activities, many of the solutions are in face of challenges to scale in Sub-Saharan Africa (SSA).
