Agriculture in Ethiopia remains to be the key sector. It is still the main source of foreign exchange earnings (up to 90%) and the largest labour force employer (about 83%). Of the total agricultural output, about 95% was covered by smallholder agriculture sub-sector. However, a number of factors limit smallholder farmers from participating in export potential cash crops. The main objective of this paper is to identify household specific factors determining sesame production and marketing participation.

Summarises the work that ILCA is doing to assemble what information is available on livestock breeds and breeding in sub-Saharan Africa.

Rice, a staple food for over 70% of Asians, is also the single biggest user of water, requiring 2-3 times more input (irrigation plus rain) water per unit of grain produced than crops such as wheat and maize. With growing populations, increased urbanisation and environmental degradation, the supply of fresh water is depleting. Recognising the water constraints to rice yield, the aim of the project entitled ‘Developing a System of Temperate and Tropical Aerobic Rice (STAR) in Asia’ was to develop water-efficient aerobic rice technologies.

The coastal zone of Bangladesh is the most vulnerable region of the eastern Ganges basin, occupies about 30% (46,000 km2) of the country’s land area and is home to some of the world’s poorest and most food insecure 39 million people, whose livelihoods depend primarily on agriculture and aquaculture. Key challenges to both agricultural and aquacultural productivity include excessive flooding during the rainy season, lack of access to fresh water and soil salinity during the dry season, and severe cyclonic storms and tidal surges throughout the year.

Agricultural water management (AWM) interventions, such as soil and water conservation or small-scale irrigation around small-scale water reservoirs, have repeatedly shown benefits to yields, soil fertility and water availability – at the field and experimental farm scale. It is assumed that these benefits will result in better and more sustainable livelihoods. However, there has been little published evidence of such wide-scale beneficial impacts.

The paper is divided into four chapters. The frist chapter is the introduction. Chapter two discusses the conceptualisation of the farming system with reference to the livestock component and reviews some alternative typologies that have been employed or proposed. A typological framework that is consistent with ILCA's objectives is then outlined. Chapter 3 develops a regionalisation of the semi arid zones of sub-Saharan Africa in four orders of increasing scale. The first order sub-division is between "West and North" and "East and South" geographical regions.

In 1986, ILCA carried out informal surveys at Dogollo and Inewari in order to understand the farming systems. Such surveys were also conducted by the Institute of Agricultural Research (IAR) at Ginchi in 1986 and by the Alemaya University of Agriculture at Ada/Debre Zeit in 1988/89. This was followed by one-time detailed formal farm surveys at Dogollo, Inewari and Ginchi in 1988/89. This chapter mostly presents the results of these formal surveys.
