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.

Book excerpt: This fourth edition of the Rice Almanac continues the tradition of the first three editions by showcasing rice as the most important staple food in the world and all that is involved in maintaining rice production. It also breaks new ground in its coverage of issues related to rice production, both environmental--including climate change--and its importance for food security and the global economy. It also further expands coverage of the world’s rice production area by featuring 80 rice-producing countries around the world.

Available in PDF, EPUB and Kindle. Book excerpt: The subak in Bali is a type of farmer-managed canal-irrigated rice cultivation system, which has long been recognised for its efficient water use and high rice productivity. Subaks are firmly embedded in local Hindu culture with institutions that guide farmers in sharing water equitably. Water sharing is based on principles of proportionality and transparency and irrigation system maintenance is egalitarian. In the 1960s, rice production was modernised and commercialised with Green Revolution technologies to feed a rapidly growing population. Some of these new technologies initially caused considerable disruption in raising the productivity of rice and irrigation efficiency. Meanwhile, Bali's formerly agriculture-based economy began to diversify with prospering tourism and other industries. Farmers engaging in part-time farming and multiple occupations off-farm have become the norm. Urban and industrial development increasingly competes for agriculture's resources, such as land, labour and water. This increasing pressure raises questions whether subaks are well-equipped to maintain their productivity and efficient resource management in the long run.

Available in PDF, EPUB and Kindle. Book excerpt: The System of Rice Intensification (SRI) involves the adoption of certain changes in management practices for rice cultivation that create a better growing environment for rice crops. The use of intermittent irrigation with alternate wet and dry intervals (AWD) and single transplanting of the younger seedlings in wider spacing areas are regarded as the key factors in SRI for better crop growth and productivity. Field experiments were conducted in Chiba, Japan during the two consecutive rice growing seasons (May-September) of 2008-09 to observe the effects of SRI components on rice crop performance, field environment, water savings, and water-wise rice production. The effects of the irrigation method, age of seedlings and spacing were evaluated in the 2008 rice season with eight treatment combinations in a split-split plot design (S-SPD). AWDI at 10 day intervals and continuous flooding throughout the cropping season were the two main plot factors while the effects of seedling age (14 and 21 days) and plant spacing (30x30 cm2 and 30x18 cm2) were evaluated as sub and sub-sub plot factors, respectively. The experimental results revealed that the SRI management with the proposed AWDI can save a significant amount of irrigation water (29%) without reduced grain yield (7.41t/h compared with 7.37t/ha from normal planting with ordinary water management). Water productivity was also observed to be significantly higher in all combinations of practices in AWDI plots: 1.74 g/liter with SRI management and AWDI as compared to 1.23 g/liter in normal planting with ordinary water management. In addition, the research outcomes showed a role of AWDI in minimizing pest and disease incidence, shortening the rice crop cycle and also improving the plant stand until harvest. Synergistic effects of younger seedlings and wider spacing were seen in tillering ability, panicle length and a number of filled grains that ultimately led to higher productivity with better grain quality. Field experiments with the complete sets of SRI practices were carried out in Randomized Complete Block Design (RCBD) during the 2009 rice growing season in the same field. SRI (with 8 day old seedlings) and conventional (with 22 day old seedlings) practices were the first factor (cultivation method), while organic and inorganic managements were evaluated as the second factor (management method) in the field experiments. The highest yield was observed through the conventional method with inorganic management (6.84t/h) that was on par with the organic SRI (6.59t/h) followed by organic conventional (6.48t/h). It was recorded as 5.92t/h in inorganic SRI management. Overall, the effects of SRI components were positive and significant on a per plant basis; however, they did not differ significantly in terms of grain yield per unit area. The development of healthy and vigorous roots, increased stem diameter, greater productive leaf area, longer panicles, greater number of filled grains, development of plants tolerant to insect-pest and disease, and reduced plant lodging percentage were some notable achievements with SRI management. Water savings and water-wise rice production are other important issues that are likely to draw the attention of rice researchers and farm communities to adopt SRI under scarce water conditions. However, comparatively better grain yields with conventional management methods underscore a need for further investigations in defining an appropriate combination of practices for SRI management, considering local soil properties, prevailing climate and critical watering stages in rice crop management.

Available in PDF, EPUB and Kindle. Book excerpt: The book examines patterns of class structure, production relations and capitala accumulation in three West Java villages. It explores the hidden assumptions underlying conventional theories of agrarian change and demonstrates the importance of class structure and class power in shaping patterns of change at the village level. Topics include the methodology of measuring class differentiation, changes in labour market institutions and real wages, and strategies of capital accumulation pursued by village elites.
