Within the Nineteen Eighties and Nineteen Nineties, eco-friendly manure/cover crop (GMCC) platforms grew to become a well-liked agricultural know-how in study and improvement efforts for smallholder tropical and subtropical farmers. even if, few syntheses of those stories were carried out. This quantity of case reports contributes to bridging this hole via reviewing field-level reports with those structures. Twelve case stories are incorporated. 11 of them describe stories from Latin the USA (4 cases), Africa (6 situations) and Asia (1 case) and the 12th case experiences at the improvement of a GMCC structures database. concluding chapters, `Learning from the Case experiences' and `Future Perspectives', construct upon the situations. The platforms defined are diversified. a few platforms were spontaneously followed by means of farmers, whereas others were brought to the farmers via diffusion efforts. the various circumstances reviewed describe small, localized efforts whereas others file on large-scale, famous ones, resembling the mix of GMCCs and conservation tillage in Santa Catarina, Brazil, the maize-Mucuna method in northern Honduras, and the enhanced fallow platforms in japanese Zambia. so much reports contain either improvement and examine elements and to the level attainable the situations combine those . dialogue of the strengths and shortcomings of the platforms and efforts is frank, and the target is to profit from those studies to learn destiny efforts. it really is anticipated that either researchers and improvement practitioners and scholars of tropical farming platforms and soil administration will locate this quantity of case stories priceless.
