Última A spatial bio-economic modelling approach on the trade-offs between global bioenergy demand, agricultural intensification, expansion, and trade AgEcon Lotze-Campen, Hermann; Popp, Alexander; Beringer, Tim; Muller, Christoph; Lucht, Wolfgang. Increased future demands for food, fibre and fuels from biomass can only be met if the available land and water resources on a global scale are used and managed as efficiently as possible. The main routes for making the global agricultural system more productive are through intensification and technological change on currently used agricultural land, land expansion into currently non-agricultural areas, and international trade in agricultural commodities and processed goods. In order to analyse the trade-offs and synergies between these options, we present a global bio-economic modelling approach with a special focus on spatially explicit land and water constraints as well as technological change in agricultural production. For a given bioenergy demand...

Ano: 2009 URL: http://purl.umn.edu/51458 A Spatial Mathematical Model Analysis of the Linkage between Agricultural Trade and Deforestation AgEcon Schmitz, Christoph; Lotze-Campen, Hermann. Like agricultural trade, deforestation has increased tremendously throughout the past five decades. We analyse the linkage between both factors by applying trade and forest policy scenarios to the global land-use model MAgPIE ("Model of Agricultural Production and its Impact on the Environment"). The model predicts global landuse patterns in a spatially explicit way and uses endogenously derived technological change and land expansion rates. Our study is the first which combines global trade analysis with a spatially explicit mapping of deforestation. By implementing self-sufficiency rates in the regional demand and supply equations, we are able to simulate different trade settings. Our baseline scenario fixes current trade patterns until the year 2045.... Tipo: Conference Paper or Presentation Palavras-chave: International Relations/Trade; Resource /Energy Economics and Policy.

Ano: 2011 URL: http://purl.umn.edu/114251 The Economics of Alternative Strategies for the Reduction of Food-borne Diseases in Developing Countries: The Case of Diarrhea in Rwanda AgEcon von Witzke, Harald; Kirschke, Dieter; Lotze-Campen, Hermann; Noleppa, Steffen. The paper provides a methodology which is suitable for the analysis of the social cost of disease and the benefits and cost of health intervention by integrating public health analysis and economics. The approach developed in the paper is applied to food-borne diarrhea in Rwanda. The results suggest that simple treatments such as Oral Rehydration Therapy have a higher social rate of return than consumer protection via education.

Ano: 2005 URL: http://purl.umn.edu/18830 The Impacts of Water Management Policies on Agricultural Production in Australia - An Economic Analysis AgEcon Burdack, Doreen; Baldwin, Claudia; Lotze-Campen, Hermann; von Witzke, Harald; Biewald, Anne. In the Australian Murray-Darling Basin (MDB) the combination of severe and prolonged droughts and historic water management decisions to divert water for cultivation stressed water resources in such an intensive manner that wetlands went dry and rivers are now far from a natural flow. More appropriate water management policies must be implemented to restore ecological function. However, with 39 % of Australia’s total value of agricultural production, transitions in use need to be managed to minimise economic and social impacts on basin communities while they adjust. Recent studies estimate that industries with high water usage but lower or more volatile value products will be impacted more than higher value products. Therefore, this study’s focus is to...

Ano: 2011 URL: http://purl.umn.edu/100534 The economics of reducing food-borne diseases in developing countries: the case of diarrhea in Rwanda AgEcon von Witzke, Harald; Kirschke, Dieter; Lotze-Campen, Hermann; Noleppa, Steffen. The paper provides a methodology which is suitable for the analysis of the social cost of disease and the benefits and cost of health intervention by integrating public health analysis and economics. The approach developed in the paper is applied to food-borne diarrhea in Rwanda. The results suggest that both prevention and treatment are socially very profitable. However, simple treatments such as Oral Rehydration Therapy have a higher social rate of return than prevention.

Ano: 2005 URL: http://purl.umn.edu/97395 IMPACTS OF LIVESTOCK FEEDING TECHNOLOGIES ON GREENHOUSE GAS EMISSIONS AgEcon Weindl, Isabelle; Lotze-Campen, Hermann; Popp, Alexander; Bodirsky, Benjamin; Rolinski, Susanne. Until 2050, the global population is projected to reach almost 9 billion people resulting in a rising demand and competition for biomass used as food, feed, raw material and bio-energy, while land and water resources are limited. Moreover, agricultural production will be constrained by the need to mitigate dangerous climate change. The agricultural sector is a major emitter of anthropogenic greenhouse gases (GHG). It is responsible for about 47 % and 58 % of total anthropogenic emissions of methane (CH4) and nitrous oxide (N2O) (IPPC, 2007). CH4 emissions are associated with enteric fermentation of ruminants, rice cultivation and manure storage; N2O emissions are related to nitrogen fertilizers and manure application to soils, but also to manure storage....

Ano: 2010 URL: http://purl.umn.edu/91277 Spatially-explicit scenarios on global cropland expansion and available forest land in an integrated modelling framework AgEcon Krause, Michael; Lotze-Campen, Hermann; Popp, Alexander. The pressure on land as required input in competing uses fuelled research on trade-offs in land use due to agricultural land expansion to meet food demand which is explicitly and implicitly treated in global land use modelling. Global land use studies rely on assessing the trade-offs by assuming policy, environmental, and economic constraints on the availability of land but do not base on consistent land use budgets. Commonly, they lack the focus on a holistic view on land use which employs different categories including trade-offs without mixing land use with land cover categories. We pursue a spatially-explicit land use budgeting approach in global available land assessment to overcome overlaps in classification. Objectives pertain to (a) identifying...

Ano: 2009 URL: http://purl.umn.edu/51751 Social rate of return to plant breeding research in Germany AgEcon von Witzke, Harald; Jechlitschka, Kurt; Kirschke, Dieter; Lotze-Campen, Hermann; Noleppa, Steffen. This article focuses on the social rate of return to plant breeding investment in Germany between 1980-2000. Starting point of the analysis is the development of total factor productivity which is decomposed into the effects of factor input and research investment. Information on investment in plant breeding have been obtained via questionnaires sent to both private plant breeding companies and public research organizations. The empirical results suggest significant underinvestment in German plant breeding research, as the calculated social rate of return is in the range of 16 to 28%.
