The National Agricultural Advisory Services (NAADS) program of Uganda is an innovative public-private extension service delivery approach, with the goal of increasing market oriented agricultural production by empowering farmers to demand and control agricultural advisory services. Although initial evaluations of NAADS have been quite favourable, these evaluations have been primary qualitative in nature. This study quantifies the initial impacts of NAADS in the districts and sub-counties where the program was operating by 2005. It is based on descriptive analyses of results of a survey of 116 farmer groups and 894 farmers in sixteen districts where the program was operating at the time and four districts where NAADS had not yet begun operating to control... |

Nitrate contamination of groundwater is an important problem. The transport of leached nitrate from the root zone to groundwater takes approximately 30 to 60 years. Many previous studies ignore this time lag by assuming instantaneous contamination. This analysis applies a delayed response model to account for the time lag between nitrogen fertilizer applications to the time the leached nitrate reaches groundwater. Results show that accounting for the leached nitrate externality reduces the nitrogen application rate by 13% and the returns above variable costs by 8% for farmers who apply both nitrogen and phosphorus. For farmers who do not use phosphorus, nitrogen use is reduced by 14% and the returns above variable costs by 22%. The application of... |

This paper investigates the patterns and determinants of change in livelihood strategies ("development pathways"), land management practices, resource and human welfare conditions in Uganda since 1990, based upon a community-level survey conducted in 107 villages. The pattern of agricultural development since 1990 involved increasing specialization and commercialization of economic activities, consistent with local comparative advantages and market liberalization. Six dominant development pathways emerged, all but one of which involved increasing specialization in already dominant activities: expansion of cereal production, expansion of banana and coffee production, non-farm development, expansion of horticultural production, expansion of cotton, and... |

This paper investigates the patterns and determinants of change in livelihood strategies (“development pathways”), land management practices, agricultural productivity, resource and human welfare conditions in Uganda since 1990, based upon a community-level survey conducted in 107 villages. The pattern of agricultural development since 1990 involved increasing specialization and commercialization of economic activities, consistent with local comparative advantages and market liberalization. This pattern was associated with changes in land use and agricultural practices, including expansion of cultivated area, grazing lands and woodlots at the expense of forest and wetlands; increased ownership of cattle but declining ownership of other livestock; and... |

The paper develops a framework for the design and analysis of pluralistic agricultural advisory services and reviews research methods from different disciplines that can be used when applying the framework. Agricultural advisory services are defined in the paper as the entire set of organizations that support and facilitate people engaged in agricultural production to solve problems and to obtain information, skills and technologies to improve their livelihoods and well-being… To classify pluralistic agricultural advisory services, the paper distinguishes between organizations from the public, the private and the third sector that can be involved in (a) providing and (b) financing of agricultural advisory services. The framework for analyzing pluralistic... |

The community-driven development (CDD) approach has become increasingly popular because of its potential to develop projects that are sustainable, are responsive to local priorities, empower local communities, and more effectively target poor and vulnerable groups. The purpose of this study is to assess the impacts of Fadama II, which is a CDD project and the largest agricultural project in Nigeria. This study used propensity score matching (PSM) to select 1728 comparable project beneficiaries and non-beneficiaries. The study also used double difference methods to compare the impact indicators. Our results show that Fadama II project succeeded in targeting the poor and women farmers in its productive asset acquisition component. Participation in the... |

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... |

Land markets, including land sales and short-term land rentals, have an important role to play for efficient and sustainable land management and agricultural development, especially where markets for other factors of production are imperfect or missing. This study utilises data from the highlands of Ethiopia, Kenya and Uganda to examine the impact of land markets on various types of land investment and management practices, crop yield, and land quality. The results highlight the relative long-term versus short-term return to different types of investment and practices, where those with longer-term benefits such as trees, manuring, and composting are preferred on more tenure-secure plots, while those with immediate or season-to-season benefits such as... |

This study investigates the impacts of rural poverty on farmers' land management decisions, crop production and incomes, based upon analysis of data from the 1999/2000 Uganda National Household Survey. We find that the impacts of rural poverty on land management, crop production and income depend upon the type of poverty (i.e., what asset or access factor is constrained) and the type of land management considered. Ugandan households that are poorer in terms of access to land use labor more intensively and are less likely to use several land management practices and inputs, though among households that do use non-labor inputs, land-poor households use many of these inputs more intensively. As a result, land-poor households obtain higher value of crop... |

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... |

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... |

Land degradation in most sub Saharan Africa is a widely recognized problem and is due in large part to poor land management practices. To address this problem, several policy-based incentives to increase the adoption of better land management practices have been proposed, including fertilizer subsidies, cash payments and, more recently, subsidized or commercially offered weather index-based insurance contracts. However, little is known about farmers’ preferences among these policy alternatives, their relative effectiveness, and their likely fiscal implications. Using survey and choice elicitation data from 271 farmers in Central Malawi, this study examines smallholder farmers’ preferences among four major policy options that provide incentives for adopting... |

Land degradation has not been comprehensively addressed at the global level or in developing countries. A suitable economic framework that could guide investments and institutional action is lacking. This study aims to overcome this deficiency and to provide a framework for a global assessment based on a consideration of the costs of action versus inaction regarding desertification, land degradation, and drought (DLDD). Most of the studies on the costs of land degradation (mainly limited to soil erosion) give cost estimates of less than 1 percent up to about 10 percent of the agricultural gross domestic product (GDP) for various countries worldwide. But the indirect costs of DLDD on the economy (national income), as well as their socioeconomic consequences... |
