Urban and peri-urban livestock farming in developing countries plays an important role in food security in cities; however it brings with it zoonotic risks. The present study was conducted to identify the most important livestock farming-related zoonotic diseases among the human population in urban and peri-urban areas of Kampala, Uganda and to assess the risks from such farming. A framework fo...

● lower stocking densities and production levels than in conventional systems (stocking densities on dairy farms on average 80% lower; on beef and sheep farms 40-80% lower). Organic certification Definitions of ‘organic’ farming vary internationally. Many countries operate national or ‘private’ standards, which do not have statutory status. The International Federation of Organic Farming Moveme...

Understanding how natural resources co-evolve with management practices is fundamental to all questions concerning their sustainable management. In the search for new pathways of sustainable development we seek to understand how comparable initial conditions in agro-ecosystems lead to fundamentally different resource conditions. Agro-ecosystems are characterized by a high diversity, path depend...

Community characteristics of Collembola assemblages in conventional, integrated and organic fields of winter wheat were compared among three randomly chosen areas in England using analysis of similarities, cluster analysis, multi-dimensional scaling and several measures of diversity and evenness. Indicator values were used to identify indicator species. Significant differences were found in the...

Statistical entropy analysis (SEA) quantifies the dilution and concentration of conservative substances (e.g., heavy metals) in a system. In this paper, the SEA concept is extended (eSEA) to make it applicable to systems in which the chemical speciation is of particular importance. The eSEA is applied to a simplified region used for crop farming. The extent to which the region concentrates or d...
