By Robert E Evenson, Douglas Gollin

This booklet studies at the productiveness affects of varietal development study carried out at a few foreign centres affiliated with the Consultative crew on foreign Agricultural examine. Such centres were on the leading edge of a 40-year attempt to reproduce new sorts of the world's staple foodstuff vegetation. The contributed chapters are the most made from a examine initiated and supported through the effect overview and assessment crew (now the status Panel on effect overview) of the CGIAR. Descriptive information and econometric versions were used to guage the effect of analysis on eleven plants and nation case reports in Brazil, China and India. The contents comprise an creation and method part (3 chapters); crop experiences on rice, wheat, maize, sorghum, pearl millet, barley, lentils, potato, cassava, groundnut and customary bean (Phaseolus vulgaris); case experiences in Brazil, China and India; and a collection of three synthesis papers reporting international and neighborhood affects on construction and human welfare. The ebook should still turn out of vital curiosity to these operating inside of plant breeding, crop technological know-how and agricultural economics. on hand In Print

This volume represents an attempt to address some of these difficult questions. Specifically, 1 In this book we define the Green Revolution in a broader context than the popular versions. We include all crops benefiting from conventional crop breeding programmes. We also include periods after 1980. E. Evenson and D. Gollin this volume grows out of a study commissioned by the Standing Panel on Impact Assessment of the Technical Advisory Committee (SPIA-TAC) of the CGIAR. The overall goal of this study was to document the impact of international research on crop genetic improvement in developing countries.

Expectations were high as colonial regimes were being ended. Many observers expected the subsequent decades to be characterized by per capita income ‘convergence’, in which the highest growth rates in per capita income would be achieved by countries with the lowest initial levels of per capita income. By the 1960s, however, it was becoming increasingly clear that maintaining food production per capita was a challenging task. Improvements in health in the 1950s and 1960s were impressive in almost all developing countries.

This role was facilitated by an international network for germplasm exchange that provides NARS breeders with ready access to breeding materials. IRRI’s success was first concentrated in irrigated rice environments and then extended to favourable rainfed environments. This success did not extend in any significant degree to upland rice environments nor to deepwater environments.
