This book is addressed to scientists, researchers, development specialists and policy makers who deal with natural resources and agriculture in the developing countries. It aims to (1) provide evidence of the impact of natural resource management research (NRMR) in the CGIAR; (2) establish a...

This chapter describes the nature of agriculture-related natural resource management research (NRMR) projects and outlines some unique features of such projects in developing countries. The main components of NRMR projects implemented by the CGIAR and its partners are discussed, and a number of...

This chapter presents conceptual frameworks to analyse agriculture-related natural resource management research (NRMR) projects and their impacts. The first part of the chapter presents an overview of adoption processes and their impacts, and is followed by an introduction of several modelling...

This chapter summarizes and compares the main features of seven case studies on impact assessment of natural resource management research (NRMR) in the CGIAR. The methodologies used by the seven case studies are described briefly. Thereafter, the main results of the studies are compared on the...

This chapter summarizes the results of seven case studies illustrative of impact assessment of natural resource management research (NRMR) in the CGIAR. Two dimensions of NRMR outcomes are discussed: adoption and investment efficiency.

This chapter offers avenues on how to improve impact assessment of agriculture-related natural resource management research (NRMR) in the future. It considers, among others, the need to upgrade documentation and monitoring, develop benchmarks, implement appropriate survey design, and include...

This chapter develops a political-economic framework of science and technology policies and presents evidence to advance the argument that, for the majority of European chemical and agricultural interests, active attempts to promote science and technology policies for agricultural biotechnology...

This chapter starts with a review of the evolution of natural resource management research in the CGIAR system and concludes with a discussion of the implications for such research in the CGIAR and for impact assessment.

This chapter reviews and synthesizes the experience with zero tillage (ZT) in the irrigated Indo-Gangetic Plains (IGP) of India so as to better understand and document the impact of this technology and related research. It first introduces the ZT technology in the context of India's rice-wheat...
