This paper examines the decline of common property resources in the arid zone of Rajasthan in India and the factors underlying the decline.The article concludes that:well-intentioned public programmes like land reformcan deprive a region of its comparative advantage in a key economic activity (in this case livestock farming)privatisation raises the cost of livestock raising and, hence, erodes the the region's comparative advantagethe continuing shrinkage and degradation of common property resources is likely to force further reduction in the size of livestock holdings and changes in their c

The present paper is based on a participatory survey carried out in order to establish baseline information on a little known livestock production system and its role in local ecology and economy.The study is based on research in El Kala National Park (North East Algeria).This paper draws attention to some of the problems that arise in understanding the cost and benefit flows in pastoralist systems.

Etude ayant pour objet de determiner, en partant d'observations cliniques faites tout au long de l'annee 1983 au niveau des troupeaux de petits ruminants suivis par le CIPEA, les causes de mortalite les plus connues avant sevrage afin de pouvoir entreprendre des essais visant a leur reduction au niveau des memes troupeaux.

Discusses the problems of livestock development in Africa - at producer, government and funding agency level; the basic constraints and planning approaches to livestock development; land tenure policies; livestock marketing & pricing policies; animal disease control and eradication policies; and behaviour of the producer in his environment.

Examines post-drought rehabilitation policies to aid recovery in livestock production and crop production, and the effects of drought on livestock and farming communities. Discusses the role played by reserves in mitigating a population's vulnerability to drought; and the macro-economic implications of a drought induced loss of livestock for the government budget, domestic markets and external trade. Investigates the likely speed of recovery in the abscence of outside intervention. Presents materials from case studies to show the nature of costs and returns involved.

Describes generally the parameters of pastoralist milk production w. partic. ref. to cattle. Discusses briefly methods of determining milk yield and milk offtake and the effect of milk production on reproductive rate. Gives a brief description of lactation curve, lactation length, calf growth and camel & small stock milk.

Examines the productivity of East African pastoral systems in terms of animal protein & energy production, milk offtake and livestock production parameters such as calving percentage, calf mortality and herd structure; compares the productivity of East African pastoral systems to those of commercial ranches and to pastoral systems in other parts of the world.

Evaluates the productivity of grade Boran cattle maintained by chemoprophylaxis under severe trypanosomiasis risk at Mkwaja ranch, Tanzania; uses data based on more than 20,000 calving records over the 10-year period from 1973 to 1982; discusses environmental influences on performance traits and links between tsetse population dynamics & cattle; includes comparison of Boran genotypes and its effect on pre-weaning growth characters.

Looks at the allocation of resources to livestock research in Africa. Assesses the role of agricultural research and its value to national governments. Investigates the appropriate criteria to use for decision making by comparing three kinds of decision-making models. Presents conclusions for policy-making.

Examines the productivity of East African pastoral systems in terms of animal protein & energy production, milk offtake and livestock production parameters such as calving percentage, calf mortality and herd structure; compares the productivity of East African pastoral systems to those of commercial ranches and to pastoral systems in other parts of the world.
