Key messages:
- Smallholder farmers and forestry producers have a crucial role to play in food security, sustainable land use and emissions reductions initiatives.
- Producers and investors alike require appropriate incentive structures to facilitate participation in sustainable land use initiatives.
- A networked financing approach—Inari—may provide an innovative response to financing sustainable land use via intelligent diversification and addressing the finance needs of smallholders.

Information on some diseases and pests that attack cassava, as well as the symptoms induced by nutritional deficiencies and toxicities and damage resulting from the misuse of herbicides are given in this manual. Specific and general recommendations regarding the control of the described problems are included. Disease control on a commercial scale is discussed. Formulae suggested for stake treatment before planting and storage and a key for identifying some cassava diseases are annexed. Color photos on symtomatology are included. (AS)

ILCA acknowledged the potential for increased animal agriculture in the subhumid zone of West Africa by establishing a research base at Kaduna in northern Nigeria. FulBe agropastoralists were selected at the target group because they own most of the cattle in the zone and cattle are the predominant livestock, at least in terms of biomass and traded products. After consultation with experts, farm surveys, and a simulation analysis, ILCA chose to focus the research on overcoming the dry-season nutrition constraint.

Intensification of land-use is inevitable for long term food security in the east African highlands, but technological options need to be environmentally safe. How forages can be used as a basis for intensified grain and fodder production from the same land unit, and serve as a profitable fallow during necessary crop-free rest period is the purpose of this study.

This chapter summarises the experience of a research project for developing and disseminating technologies for better management of Vertisols for improving productivity.

Short-term trends show that livestock production is becoming an increasingly important factor in regional development, possibly because of the combined effect of increasing the forages on offer and planting crops better adapted to the environmental and economic conditions of marginal areas and the decreasing interest of the State in expanding the agricultural frontier. Overall planning of land use should be improved, but to do so, a more detailed characterization and monitoring of deforestation are essential.
