Última Development and Dissemination of Improved Cassava Varieties in Uganda: Analysis of Adoption Rates, Variety Attributes and Speed of Adoption AgEcon Abele, Steffen; Twine, Edgar; Ntawuruhunga, Pheneas; Baguma, Yonah; Kanobe, Charles; Bua, Anthony. The transition out of extreme poverty and hunger in agrarian economies requires an understanding of how new agricultural technologies are adopted by poor farmers. In Uganda, improved germplasm from the cassava breeding program has generated new varieties that are increasingly being grown by farmers. Although considerable success has been achieved in adoption of these varieties in general, there is increasing pressure on breeding and technology dissemination programs to improve the targeting of their efforts. This paper identifies the specific cassava varieties adopted thus far and their desirable and undesirable attributes. In addition, it determines the adoption rates of these varieties and the factors that have influenced the speed of adoption of the...

Ano: 2008 URL: http://purl.umn.edu/52198 Effects of Market and Policy Shocks on the Canadian and U.S. Cattle and Beef Industries AgEcon Twine, Edgar; Rude, James. The paper examines the impact of four exogenous shocks – exchange rate appreciation, feed price escalation, mandatory country of origin labeling, and economic recession – on the Canadian and U.S. beef cattle industries using a multi-market partial equilibrium model. Impacts on the U.S. industry are found to be relatively small compared to those on the Canadian industry. Country of origin labeling, and feed price escalation account for the largest decline in the welfare of Canadian cattle producers.

Ano: 2012 URL: http://purl.umn.edu/123565 The Niger Food Crisis: Causes and Implications for Research and Development from an Integrated Agricultural Economics Perspective AgEcon Abele, Steffen; Twine, Edgar. During the 2004 food crisis in Niger, the weakness of the main production system, millet, to produce enough food to sustain short term crises, has been revealed. Questions arise how the Nigerian smallholder systems can be assisted by research and development policies to intensify production and improve food security. The paper assesses technical options according to their economic sustainability. A sequence of models is applied: On plot level, production functions of inter cropping systems were estimated to determine yields and their variability of the major crops. These data were fed in a nonlinear program to test the inn ovations, first at stable prices, then at declining prices that were obtained from an interregional trade model. The latter was shocked...
