This book presents a comprehensive overview of a range of concepts, methods, strategies and policies in agriculture and natural resource management, environmental economics, production economics and sustainable agricultural development.It explores effective analytical tools and science, innovations, and management solutions to enhance yields, manage the supply chain, strengthen institutional mechanisms, and service and support systems for farmers. It highlights the importance of enabling policies which can benefit farmers, resulting in cost-efficient and quality-improving farm practices, increased profits and income for farmers, and better management of natural resources. The essays in the book honour the academic, teaching, and research contributions of Professor R. Ramanna in the field of agricultural economics. They also address issues which are relevant to the growing research in sustainable agricultural development and natural resource management including the use of new concepts, tools, analyses, technologies, innovations, and policy strategies modelled in local contexts that can easily be scaled and applied to similar contexts elsewhere.This book will be of interest and use to students, researchers, practitioners,and policymakers working in varied fields of agricultural economics, sustainable development, public policy, rural sociology, political economy, economics of innovation, institutional economics, and industrial organisation.
