This book was released on 1995 with total page 991 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fragile lives in fragile ecosystems: Feeding the world's poor from neglected rice ecosystems was the theme of the 1995 International Rice Research Conference. During the February meeting, participants assessed progress in rice research and identified new research approaches for reducing constraints and improving productivity and sustainability of less favored and fragile rice producing areas - these are the upland, rainfed lowland, and flood-prone ecosystems.

Download or read book Economic gains of improving soil fertility and water holding capacity with clay application the impact of soil remediation research in northeast Thailand written by Saleth, R. M., Inocencio, A., Noble, A. D., Ruaysoongnern, S. and published by IWMI. This book was released on 2009 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 for the sample, and a NPV of US$21 million with a BCR of 75 for the region.

Book excerpt: "Throughout the last century, specialisation and intensification were buzz words for farmers in the Western world. However, this approach has not resulted in sustainable development as evidenced by the fact that scientists now need to create technologies to reduce negative impacts. In this book we demonstrate that an alternative exists. Case studies from Bangladesh, Thailand, and Vietnam show that integration and diversification increase both farm productivity and farmers’ incomes. By adopting a participatory approach, farmers and scientists identified a range of technologies that strengthen the positive impacts of integrated aquaculture-agriculture systems for the environment. This book is a collection of refereed papers on a controversial subject in agricultural development. Arguing that sustainability of fish culture in ponds needs a new paradigm - feed the pond to grow fish - two chapters focus on nutrient cycling in such systems. Another chapter makes the case for breeding Nile tilapia for resource poor farmers and presents practical options to avoid the pitfalls that arise from natural tilapia mating in low-input ponds. The book contains chapters on livelihood and development aspects and ends with a general discussion completing the picture of the integrated aquaculture-agriculture systems. Overall it composes a review which addresses one of the key issues of the new century: how to sustainably produce food without compromising environmental integrity."
