| Understanding how households escape poverty depends on understanding how they accumulate assets over time. Therefore, identifying the degree of linearity in household asset dynamics, and specifically any potential asset poverty thresholds, is of fundamental interest to the design of poverty reduction policies. If household asset holdings converged unconditionally to a single long run equilibrium, then all poor could be expected to escape poverty over time. In contrast, if there are critical asset thresholds that trap households below the poverty line, then households would need specific assistance to escape poverty. Similarly, the presence of asset poverty thresholds would mean that short term asset shocks could lead to long term destitution, thus... |

| Land degradation, in the form of soil erosion and nutrient depletion, threatens food security and the sustainability of agricultural production in many developing countries. Governments and development agencies have invested substantial resources in promoting soil conservation practices, in an effort to improve environmental conditions and reduce poverty. However, very limited rigorous empirical work has examined the economics of adopting soil conservation technology. This paper investigates the impact of stone bunds1 on crop production value per hectare in low and high rainfall areas of the Ethiopian highlands using cross-sectional data from more than 900 households having multiple plots per household. We use modified random effects models, stochastic... |

| Ethiopia is at a critical crossroads with a large and increasing population, a depressed national economy, insufficient agricultural production, and a low number of developed energy sources. The upper Blue Nile basin harbors considerable untapped potential for irrigation and hydropower development and expansion. Numerous hydrologic models have been developed to assess hydropower and agricultural irrigation potential within the basin, yet often fail to adequately address critical aspects, including the transient stages of large-scale reservoirs, relevant flow retention policies and associated downstream ramifications, and the implications of stochastic modeling of variable climate and climate change. A hydrologic model with dynamic climate capabilities is... |

| The threats posed by invasive plants span ecosystems and economies worldwide. Local knowledge of biological invasions has proven beneficial for invasive species research, but to date no work has integrated this knowledge with species distribution modeling for invasion risk assessments. In this study, we integrated pastoral knowledge with Maxent modeling to assess the suitable habitat and potential impacts of invasive Cryptostegia grandiflora Robx. Ex R.Br. (rubber vine) in Ethiopia’s Afar region. We conducted focus groups with seven villages across the Amibara and Awash-Fentale districts. Pastoral knowledge revealed the growing threat of rubber vine, which to date has received limited attention in Ethiopia, and whose presence in Afar was... |

| The primary goal of emergency food aid after an economic shock is often to bolster short-term food and nutrition security. However, these transfers also act as insurance against other shock effects, such as destruction of assets and changes in economic activity, which can have lasting deleterious consequences. Although existing research provides some evidence of small positive impacts of timely food aid disbursements after a shock on current food consumption and aggregate consumption, little is known about whether these transfers play a safety net role by reducing vulnerability and protecting assets into the future. We investigate this issue by exploring the presence of persistent impacts of two major food aid programs following the 2002 drought in... |

| Ethiopia experiences a fierce political debate about the appropriate land tenure policy. After the fall of the socialist derg regime in 1991, land property rights have remained vested in the state and only usufruct rights have been alienated to farmers – to the disappointment of international donor agencies. This has nurtured an antagonistic debate between advocates of the privatization of land property rights to individual plot holders and those supporting the government’s position. This debate, however, fails to account for the diversity and continuities in Ethiopian land tenure systems. This paper reviews the changing bundles of rights farmers have held during various political regimes in Ethiopia, the imperial, the derg and the current one, at... |

| Rural and urban spaces are usually regarded as “separate” in both development theory and practice. Yet there are myriad links between them. Urban areas, including regional urban centers such as local market towns, provide households with new opportunities to sell goods and services. These opportunities increase household income by employing previously unemployed household resources or because households reallocate household resources so as to take advantage of new, more profitable activities. Links to market towns improve the prices received by rural households because households can benefit from increased demand for their goods or because the larger market is better able to absorb production from rural areas without causing prices to decline. These links... |

| Although 22 percent of land in sub-Saharan Africa is arid or semiarid rangeland, development policies have long been biased toward crop agriculture. In the wake of the Green Revolution, international and national agricultural research institutions focused on crop systems and plant breeding. As a result, the customary tenure arrangements that enabled pastoralists to move their livestock from one grazing ground to another fell out of favor. As climate-related crises and desertification have spiraled, however, research and policy interest in rangeland management issues have been renewed. As part of its strategy to seek policies for the efficient functioning of global food systems, IFPRI has been in the forefront of this research. In the 1990s, as part of a... |

| The purpose of this report is to assess the efficiency of the Ethiopian grain marketing system and identify some of the constraints on market participants which influence its performance. The main questions dealt with are: How is the grain marketing system organized and coordinated? Is the grain trade business composed of many small units competing one another or is it dominated by few large participants? What are the approaches followed by traders in buying, selling and pricing grain? Are there any barriers to entry, and if so, what are the major factors? What problems and constraints are observed in transportation, storage, financial credit, and market information? How have the structure and conduct of the market and the constraints and problems... |

| The availability of enabling institutions, information systems and infrastructure is a precondition to enhance agricultural markets’ efficiency, and make market actors less vulnerable to price instability. This paper investigates whether the focus on institutional and technological upgrading is enough to make Ethiopian agricultural markets more efficient. In particular, given that a requirement for exchange efficiency is the lack of unexploited mutually beneficial spatial arbitrage opportunities, we look for evidence of increasing returns to transaction size and returns to scale in transport using detailed trader surveys collected in 2001 and 2007. Whilst transport costs could be reduced by assembling loads and avoiding trans-shipments for the... |
