Última Development, Diffusion and Impact of Conservation Farming in Zambia AgEcon Haggblade, Steven; Tembo, Gelson. The study reported in this paper measures differences in profitability between conservation farming (CF) practices and conventional agriculture by comparing the value of differential output with the differential input costs. The main objective is to address and fill several important knowledge gaps by investigating three key features of conservation farming in Zambia: 1) the process by which CF originated and spread; 2) the scale of CF adoption across household groups and regions; and 3) the impact of CF on crop output, input use, cost of production and farm income.

Ano: 2003 URL: http://purl.umn.edu/54464 An Assessment of the Economic Impacts of NSW Agriculture Research and Extension - Conservation Farming and Reduced Tillage in Northern NSW AgEcon Scott, J. Fiona; Farquharson, Robert J.. This assessment of research and extension in conservation farming in northern NSW was done as part of a systematic process of evaluating the economic, social and environmental impacts of major research, extension and education programs. The conservation farming program was a key area of investment by NSW Agriculture and an evaluation process fulfils accountability and resource allocation requirements. This analysis evaluates the investments by the former NSW Agriculture in conservation farming and reduced tillage programs from the late 1970s to 2002. The benefit-cost ratios (BCR) for no till only and no till plus reduced tillage practices up to 2002 were 4.1:1 and 9:1, respectively. The net present values (NPV) of the benefits from these efforts up to 2002...
