Última Economic gains of improving soil fertility and water holding capacity with clay application: the impact of soil remediation research in northeast Thailand AgEcon Saleth, Rathinasamy Maria; Inocencio, Arlene; Noble, Andrew D.; Ruaysoongnern, Sawaeng. Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44...

Ano: 2009 URL: http://purl.umn.edu/53064 Tracking Foodborne Pathogens from Farm to Table: Data Needs to Evaluate Control Options AgEcon Food safety policymakers and scientists came together at a conference in January 1995 to evaluate data available for analyzing control of foodborne microbial pathogens. This proceedings starts with data regarding human illnesses associated with foodborne pathogens and moves backwards in the food chain to examine pathogen data in the processing sector and at the farm level. Of special concern is the inability to link pathogen data throughout the food chain. Analytical tools to evaluate the impact of changing production and consumption practices on foodborne disease risks and their economic consequences are presented. The available data are examined to see how well they meet current analytical needs to support policy analysis. The policymaker roundtable...

Ano: 1995 URL: http://purl.umn.edu/33549 A framework for efficient wastewater treatment and recycling systems AgEcon Mekala, Gayathri Devi; Davidson, Brian; Samad, Madar; Boland, Anne-Maree. Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.
