Food Aid Targeting in Ethiopia: A Study of Household Food Insecurity and Food Aid Distributions AgEcon
Clay, Daniel C.; Molla, Daniel; Habtewold, Debebe.
This paper examines the efficiency of food aid targeting in rural Ethiopia based on empirical evidence from a survey of a nationally representative sample of 4,166 farm households conducted by the Grain Market Research Project (GMRP) of MEDAC in collaboration with the Central Statistical Authority (CSA). The survey was administered in June 1995 and covered the 12-month period from the beginning of the 1995 meher harvest to the beginning of the 1996 meher harvest.

HETEROGENEOUS CONSTRAINTS, INCENTIVES AND INCOME DIVERSIFICATION STRATEGIES IN RURAL AFRICA AgEcon
Barrett, Christopher B.; Bezuneh, Mesfin; Clay, Daniel C.; Reardon, Thomas.
A burgeoning recent literature emphasizes "livelihood" diversification among smallholder populations (Chambers and Conway 1992, Davies 1993, Ellis 1998, Bryceson 1999, Ellis 2000, Little et al. 2001). While definitions vary within this literature, the concept of livelihoods revolves around the opportunity set afforded an individual or household by their asset endowment and their chosen allocation of those assets across various activities to generate a stream of benefits, most commonly measured as income. This holistic perspective has the potential to enhance our understanding of the strategies that farm households pursue to ensure food and income security given the natural and economic environment in which they operate. Diversification patterns...

Improving Information and Performance in Grain Marketing: an Assessment of Current Market Information Systems, and Recommendations for Developing a Public Grain MIS AgEcon
Tschirley, David L.; Diskin, Patrick K.; Molla, Daniel; Clay, Daniel C..
This paper focuses on one dimension which is at the core of all modern economies: how to provide private and public agents with timely and accurate information regarding current and expected future market conditions. Its objective is to show the need for a public market information system for agricultural markets in Ethiopia, and to present concrete proposals that can be reviewed, debated, and modified as necessary by the relevant Ethiopian authorities in collaboration with Food Security Research Project (FSRP) personnel.

Input Use and Conservation Investments among Farm Households in Rwanda: Patterns and Determinants AgEcon
Clay, Daniel C.; Kelly, Valerie A.; Mpyisi, Edson; Reardon, Thomas.
One of the Government of Rwanda’s key post-war policy objectives has been to increase agricultural productivity and ensure food security by promoting a transition from semi-subsistence production and marketing practices to intensive production and highly commercialized agricultural markets. The government wants farmers to increase land and labor productivity through the use of modern inputs, thereby generating substantial surpluses which can be sold to pay for inputs and generate increases in farm incomes.

Land Use, Soil Loss and Sustainable Agriculture in Rwanda AgEcon

POPULATION AND LAND DEGRADATION AgEcon
Clay, Daniel C.; Guizlo, Mark; Wallace, Sally.
In this paper, we argue that there exist no significant direct links between human populations and their environments and that the intervening processes create the context within which land degradation occurs. We examine some of the intermediate mechanisms through which mounting demographic pressure leads to soil erosion and the depletion of soil fertility. The focus of attention is on set of variables defined in this paper as the structure of landholding (size of holdings, fragmentation/ dispersion, fragility, tenure, etc.). How demographically-induced changes in the structure of land-holding affect land management strategies (investments and land use) is key to understanding land degradation. Traditional perspectives on population and agricultural...

Population and Sustainability: Understanding Population, Environment, and Development Linkages AgEcon
Clay, Daniel C.; Reardon, Thomas.
The triple challenge of rapid population growth, declining agricultural productivity, and natural resource degradation are not isolated from one another; they are intimately related. However, strategic planning and development programming tend to focus on individual sectors such as the environment, agriculture, and population; they do not explicitly take into account the compatibilities and inconsistencies among them. Farm households and their livelihood strategies are at the core of the intersectoral linkages approach advocated in this chapter. Three key aspects of the population-environment-development debate are discussed: first, the finding that inconsistencies between public and individual household behavior regarding childbearing and family planning...

Promoting Food Security in Rwanda Through Sustainable Agricultural Productivity: Meeting the Challenges of Population Pressure, Land Degradation, and Poverty AgEcon
Clay, Daniel C.; Byiringiro, Fidele Usabuwera; Kangasniemi, Jaakko; Reardon, Thomas; Sibomana, Bosco; Uwamariya, Laurence; Tardif-Douglin, David.
The horror of genocide and civil war have turned the world's attention to Rwanda over the last year. But before and beyond that conflict, there was hunger and the slow grinding poverty of small holder agriculture meeting with severe land scarcity and degradation. This report is about reversing the spiraling decline of the land and the economy in rural Rwanda. Three things conspire to accelerate this decline: unsustainable land use practices, insufficient non-farm employment, and rapid population growth. We focus on the forces behind productivity decline in Rwandan agriculture. This report examines how erosion, organic input use, soil conservation investments, use of fertilizer and lime, and land use strategies affect productivity. We then examine what...
