The economic role of cattle in communal farming systems in Zimbabwe

Décembre, 1991
Zimbabwe
Afrique sub-saharienne

This paper is concerned with understanding cattle production in Zimbabwe's Communal Lands, in so-called communal farming systems. Although commercial offtake from Zimbabwe's communal cattle herd is low, communal farmers are productive and rational in their cattle herd management. The economic rationale for cattle ownership is firstly to provide draught power and manure for tillage and secondly to provide milk and meat for local consumption, although the role of livestock in the farming system varies significantly from one part of Zimbabwe to another.

Australie

This Statement outlines agreed objectives and policies for the future of Australia's public and private forests. The Governments share a vision of ecologically sustainable management of Australia's forests. This vision has a number of important characteristics: 1) The unique character of the Australian forested landscape and the integrity and biological diversity of its associated environment is retained. 2) The total area of forest is increased. 3) There is a 'holistic' approach to managing forests for all their values and uses so as to optimise benefits to the community.
