Presents a general description of pastoralist milk production from cattle in Africa, analyzing data on milk yield & offtake, lactation and milk composition under pastoralist conditions; briefly examines the use of milk from camels and smallstock by pastoralsits to complement their milk supply from cattle.

Examines the extent and methods of crop production in the Fulani agropastoral system in central Nigeria by analyzing cropping patterns, management techniques employed, and inputs to cropping such as labour, draught power & fertilizers, and output in terms of grain yield, energy and crop residues.

Reviews various approaches and techniques used in a number of sub-Saharan African countries to collect and analyze data on large-scale ecological changes with particular reference to remote sensing and monitoring techniques in resource inventory; suggests ways to build more effective data bases.

Presents findings and proposals of a team which studied the pastoral zone of Niger to forumlate a development programme, describing the existing production systems and constraints related to range resources, nutrition, water points and diseases.

Discusses biological options available for improvement in the productivity of pastoral systems, particularly referring to problems arising from aridity and under-nutrition, and problems of particular systems such as mortality of young stock, bush encroachment, epidemic diseases and management systems.

Indicates factors that must be considered when designing pastoral systems research, esp. the need to maintain complementantrity among various types of research; the need for policy orientation when carrying out research; and setting up of priorities & opportunities. Includes case examples from work carried out by the ILCA subhumid programme.

Discusses ways of studying economics of household level activities in pastoral production systems, with particular reference to the collection and analysis of data on household income and expenditure as well as resources inventory.
