Download or read book White Gold The Commercialisation of Rice Farming in the Lower Mekong Basin written by Rob Cramb and published by Springer Nature. This book was released on 2020-01-03 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is about understanding the processes involved in the transformation of smallholder rice farming in the Lower Mekong Basin from a low-yielding subsistence activity to one producing the surpluses needed for national self-sufficiency and a high-value export industry. For centuries, farmers in the Basin have regarded rice as “white gold”, reflecting its centrality to their food security and well-being. In the past four decades, rice has also become a commercial crop of great importance to Mekong farmers, augmenting but not replacing its role in securing their subsistence. This book is based on collaborative research to (a) compare the current situation and trajectories of rice farmers within and between different regions of the Lower Mekong, (b) explore the value chains linking rice farmers with new technologies and input and output markets within and across national borders, and (c) understand the changing role of government policies in facilitating the on-going evolution of commercial rice farming. An introductory section places the research in geographical and historical context. Four major sections deal in turn with studies of rice farming, value chains, and policies in Northeast Thailand, Central Laos, Southeastern Cambodia, and the Mekong Delta. The final section examines the implications for rice policy in the region as a whole.

Download or read book Changes in Paddy Soil Fertility in Tropical Asia under Green Revolution written by Junta Yanai and published by Springer Nature. This book was released on 2022-06-20 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the effect of the Green Revolution (GR) on long-term changes in the fertility status of paddy soils in tropical Asia. While information on long-term changes in soil fertility status are rather limited due to difficulties in obtaining past data or samples for comparison, this investigation on temporal changes in soil fertility is possible by comparing fertility status in the 2010s, which the authors examined recently, with those from the 1960s, when GR was initiated, which was reported by Kawaguchi & Kyuma (1977). More than 220 paddy soils collected from Thailand, the Philippines, Malaysia, Bangladesh, and Indonesia were analyzed for their physicochemical properties as well as total and available fractions of plant macro- and micro- essential elements, and their temporal changes were examined in addition to their spatial variation in each country. The most significant change was a drastic increase of available phosphorus in soils, possibly due to fertilization after the GR. Changes in organic matter, pH, and other nutrients were relatively small. A considerable decrease in the content of some micronutrients was also observed. Long-term studies on soil fertility status in the past and present will be useful to establish soil/fertilizer management for sustainable rice production in the future. This book is an essential reading for soil scientists, agricultural scientists, environmental scientists, as well as policymakers and nongovernmental officers such as FAO.
