Book Description
The paper jointly evaluates the determinants of switching to modern rice and its productivity while allowing for production inefficiency at the level of individual producers. Model diagnostics reveal that serious selection bias exists, justifying the use of a sample selection framework in stochastic frontier models. Results revealed that modern variety selection decisions are influenced positively by the availability of irrigation and gross return from rice and negatively by a rise in the relative wage of labour. Adoption of modern rice is higher in underdeveloped regions. Seasonality and geography/location does matter in adoption decisions. Stochastic production frontier results reveal that land, labour and irrigation are the significant determinants of modern rice productivity. Decreasing returns to scale prevail in modern rice production. The mean level of technical efficiency (MTE) is estimated at 0.82. Results also demonstrate that the conventional stochastic frontier model significantly overestimates inefficiency by three points (MTE=0.79). Policy implications include measures to increase access to irrigation, tenurial reform and keeping rice prices high to boost farm returns and offset the impact of a rise in the labour wage which will synergistically increase the adoption of modern rice as well as farm productivity.

Book Description
Changing Climate and Resource Use Efficiency in Plants reviews the efficiencies for resource use by crop plants under different climatic conditions. This book focuses on the challenges and potential remediation methods for a variety of resource factors. Chapters deal with the effects of different climatic conditions on agriculture, radiation use efficiency under various climatic conditions, the efficiency of water and its impact on harvest production under restricted soil moisture conditions, nitrogen and phosphorus use efficiency, nitrogen use efficiency in different environmental conditions under the influence of climate change, and various aspects of improving phosphorus use efficiency. The book provides guidance for researchers engaged in plant science studies, particularly Plant/Crop Physiology, Agronomy, Plant Breeding and Molecular Breeding. In addition, it provides valuable insights for policymakers, administrators, plant-based companies and agribusiness companies. Explores climatic effects on agriculture through radiation, water, nitrogen, and phosphorus-use efficiency Guides the planning and research of, and recommendations for, fertilizer application for different crops under various climatic conditions Discusses efficiency improvements for plant and molecular breeders seeking to maximize resource use

Book Description
One of the most exciting recent innovations in the social sciences has been the emergence of 'behaviour economics', which extends the notion of rational choice to allow for both motivation beyond self-interest and intuitions that cannot be reduced to the logic of a situation. This new book by Howard Margolis demonstrates how an account of widely-di

Book Description
Natural Resources and the Environment: Economics, Law, Politics, and Institutions provides a new approach to the study of environmental and natural resource economics. It augments current contributions from the fields of public choice, law, and economics, and the burgeoning field of what used to be called the "New Institutional Economics," to describe, explain, and interpret how these new developments have been applied to better understand the economics of natural resources and the environment. This textbook takes a multi-disciplinary approach, which is essential for understanding complex environmental problems, and examines the issue from not only an economic perspective, but also taking into account law, politics, and institutions. In doing so, it provides students with a realistic understanding of how environmental policy is created and presents a comprehensive examination of real-world environmental policy. The book provides a comprehensive coverage of key issues, including renewable energy, climate change, agriculture, water resources, land conservation, and fisheries, with each chapter accompanied by learning resources, such as recommended further reading, discussion questions, and exercises. This textbook is essential reading for students and scholars seeking to build an interdisciplinary understanding of natural resources and the environment.

Book Description
The conference on âInterdisciplinary Research in Technology and Managementâ was a bold experiment in deviating from the traditional approach of conferences which focus on a specific topic or theme. By attempting to bring diverse inter-related topics on a common platform, the conference has sought to answer a long felt need and give a fillip to interdisciplinary research not only within the technology domain but across domains in the management field as well. The spectrum of topics covered in the research papers is too wide to be singled out for specific mention but it is noteworthy that these papers addressed many important and relevant concerns of the day.

Book Description
Tropentag is the largest interdisciplinary conference in Europe focusing on development- oriented research in the fields of tropical and subtropical agriculture, food security, natural resource management and rural development. It is clear that a just and sustainable transformation of our food systems is urgently needed: climate change, conflicts, rising food and fuel prices, and growing social and income inequalities are exacerbating the vulnerabilities of our food systems. The theme invites diverse contributions that explore different pathways for transforming food systems and the trade-offs and synergies involved, ranging from more technical solutions, such as climate-smart agriculture and biofortified crops, to more systematic solutions for changing the underlying relationships of our food systems, such as agroecology and alternative food networks.
