| Spatial and temporal attributes of watersheds and associated market failures require institutional arrangements for coordinating use and management of natural resources. Effective collective action (CA) for watershed management has the potential to provide multiple economic and environmental benefits - tangible and non-tangible - to rural communities. This allows smallholder farmers to jointly invest in management practices that provide collective benefits to community members. The functions of the group can also extend to include provision of new services like collective marketing of products and essential inputs. While watershed management contributes to resource productivity and sustainability, increased commercialization and market access open... |

| This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the... |

| This study analyzes how market imperfections affect land productivity in a degraded low-potential cereal- livestock economy in the Ethiopian highlands. A wide array of variables is used to control for land quality in the analysis. Results of three different selection models were compared with least squares models using the HC3 heteroskedasticity-consistent covariance matrix estimator. Market imperfections in labor and land markets were found to affect land productivity. Land productivity was positively correlated with household male and female labor force per unit of land. Female-headed households achieved much lower land productivity than male- headed households. Old age of household heads was also correlated with lower land productivity. Imperfections in... |

| Soil fertility and the lack of fertilizer use in Africa are frequently discussed topics. The problems of land degradation and low agricultural productivity, which result in food insecurity and poverty, are particularly severe in the rural highlands of Ethiopia. In many areas, a downward spiral of land degradation and poverty appears to be occurring. Finding solutions to these problems requires identifying effective entry points for farmers, governments, and civil society organizations, and understanding the potential impacts and tradeoffs that are likely to arise from alternative interventions. This report seeks to improve that understanding, using a bioeconomic model of land management and agricultural production developed for a community that is fairly... |

| The paper examines the interlinkages between population pressure and poverty, possible impacts on household welfare and land management, and the consequent pathways of development in a low potential rural economy. A dynamic non-separable bio-economic model, calibrated using data from the Ethiopian highlands, is used to trace key relationships between population pressure, poverty and soil fertility management in smallholder agriculture characterized by high levels of soil degradation. Farm households maximize their discounted utility over the planning horizon. Land, labor and credit markets are imperfect. Hence, production, consumption and investment decisions are jointly determined in each period. The level of soil degradation is endogenous and has... |
