Book Description
In order to achieve economic efficiency, research organizations have established rigorous, quantitative methods for priority setting. One such organization, the Rockefeller Foundation, has drawn on this report to help determine the research goals it should emphasize in its funding. A review of the problem of priority setting is presented followed by a discussion of approaches that have been used previously. Several chapters demonstrate how a number of areas of plant science research have contributed to gains in rice productivity and also assess the current challenges of genetic improvement and pest control. The economic framework for priority setting and previous methods are reviewed, followed by a series of country case studies which provide more practical applications.

Book Description
Rice production is affected by changing climate conditions and has the dual role of contributing to global warming through emissions of the greenhouse gas methane. Climate change has been recognized as a major threat to the global environment. Because of insufficient field data, rice-growing countries face a problem when trying to comply with the United Nations Framework Convention on Climate Change stipulations to compile a national inventory of emissions and to explore mitigation options. Given the expected doubling in rice production in Asia, the need to evaluate the interaction between climate change and rice production is critical to forming a sound basis for future directions of technology developments by policy makers, agriculturists, environmentalists, rice producers, and rice consumers. The present book comprises two sections. The first part documents a comprehensive overview of the results achieved from an interregional research effort to quantify methane emission from major rice ecosystems and to identify efficient mitigation options. This research report broadens understanding of the contribution of rice cultivation to methane emissions and clarifies that emissions are relatively low, except in specific rice ecosystems, and that these high emissions could be ameliorated without sacrificing yield. The second section shows results from other projects that investigated the role of rice cultivators in field and laboratory approaches. The findings represent inputs for future modeling approaches in the role of rice cultivators. The expanded database generated by other projects is reflected in modeling efforts.

Book Description
This book provides a comprehensive yet accessible overview of land systems vulnerability assessment in Asia - fundamental to the understanding of the link between global change, environmental sustainability and human wellbeing. The extent and intensity of human interactions with the environment have increased spectacularly since the Industrial Revolution. Thus, the global change research community and development practitioners increasingly recognize the need to address the adverse consequences of changes taking place in the structure and function of the biosphere and the implications for society. With a focus on Asia, this book provides an overview of the vulnerability of land systems and the subsequent multiple stressors in this region. The book offers a discussion surrounding the potential causal processes that affect land systems vulnerability and our capacity to cope with different perturbations. It also identifies factors that help to integrate vulnerability assessment into policy and decision-making. • Addresses the complex issues arising from human–environment interactions that cannot be satisfactorily dealt with by core disciplinary methods alone. • Key coverage of a variety of topics from the vulnerability of smallholder agriculture and urban systems to the impact of socioeconomic processes at the sub-regional level. • Coverage of the causal processes that affect land systems vulnerability and capacity to cope with different perturbations are documented. • Focus on integrating vulnerability assessment into policies and decision-making • Includes contributions from leading academics in the field.
