| This paper estimates a structural econometric model of household decisions regarding income strategies, participation in programs and organizations, crop choices, land management, and labor use, and their implications for agricultural production and land degradation; based upon a survey of over 450 households and their farm plots in Uganda. The results generally support the Boserupian model of population-induced agricultural intensification, but do not support the "more people-less erosion" hypothesis, with population pressure found to contribute to erosion in the densely populated highlands. Agricultural technical assistance programs have location-specific impacts on agricultural production and land degradation, contributing to higher value of crop... |

| It is often the case that national policies are not necessarily suitable at lower administrative levels due to the spatial complexity of natural and socio-economic resources within a country. That complexity of resources can be resolved by spatial modeling of natural and socio-economic variation. We propose a new GIS-based stratification algorithm to demarcate homogenous development domains at national level and applied that algorithm to Uganda. Based on that stratification, we assembled various spatial information to assess comparative advantages and disadvantages of these development domains for potential pathways of economic development. We expect that our stratification strategy may help policy makers and regional planners to target development... |

| We investigate the impacts of coffee and cotton production on land management and land degradation in Uganda, based on a survey of 851 households and soil measurements in six major agro-ecological zones, using matching and multivariate regression methods. The impacts of cash crop production vary by agro-ecological zones and cropping system. In coffee producing zones, use of organic inputs is most common on plots growing coffee with other crops (mainly bananas), and least common on mono-cropped coffee. Both mono-cropped coffee and mixed coffee plots have lower soil erosion than other plots in coffee producing zones because of greater soil cover. Potassium depletion is much greater on mixed banana-coffee plots. In the cotton production zone, few land... |

| Poverty reduction is one of the overarching objectives of most of Sub-Saharan Africa and other low-income countries. Accordingly, one of IFPRI’s major research themes focuses on policies and strategies for poverty reduction. This research report contributes knowledge to that theme. It also contributes to IFPRI’s ongoing investigation of policies and strategies that foster broad-based and environmentally sustainable agricultural and rural development. In Uganda, where soil erosion and depletion of soil nutrients are widespread, land degradation is a major cause of declining productivity and increasing poverty. In this study, Ephraim Nkonya and his colleagues measure the relative merits of various household income strategies and land management practices in... |
