Participatory technology development (PTD) is an approach to learning and innovation that is used in international development as part of projects and programmes relating to sustainable agriculture. The approach involves collaboration between researchers and farmers in the analysis of agricultural problems and testing of alternative farming practices. == Origins == The origins of Participatory Technology Development can be found in a number of approaches, concepts and techniques that became popular in the 1970s and 1980s: * Farming systems research and extension, an approach that introduced social-economic issues into organisations previously dominated by biological and chemical scientists. FSR/E also promoted the idea on 'on-farm' trials; * Appropriate technology, a concept that recognises the importance of matching the design of technology to the resources and culture of the user. * Indigenous technical knowledge, a concept that recognised the importance of local expertise and traditional wisdom; * Participatory rural appraisal, a set of techniques that promoted the involvement of rural people in decision-making. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Participatory technology development」の詳細全文を読む スポンサード リンク
