Why, despite an emphasis on 'getting institutions right', do development initiatives so infrequently deliver as planned? Why do many institutions designed for natural resource management e.g. Water User Associations, Irrigation Committees, Forest Management Councils not work as planners intended? This book disputes the model of development by design and argues that institutions are formed through the uneven patching together of old practices and accepted norms with new arrangements. The managing of natural resources and delivery of development through such processes of 'bricolage' is likened to 'institutional 'DIY' rather than engineering or design. The author explores the processes involved in institutional bricolage; the constant renegotiation of norms, the reinvention of tradition, the importance of legitimate authority and the role of people themselves in shaping such arrangements. Bricolage is seen as an inevitable, but not always benign process; the extent to which it reproduces social inequalities or creates space for challenging them is also considered. The book draws on a number of contemporary strands of development thinking about collective action, participation, governance, natural resource management, political ecology and wellbeing. It synthesises these to develop new understandings of why and how people act to manage resources and how access is secured or denied. A variety of case studies ranging from the management of water Zimbabwe, India, Pakistan, conflict and cooperation over land, grazing and water Tanzania, and the emergence of community management of forests Sweden, Nepal, illustrate the context specific and generalised nature of bricolage and the resultant challenges for development policy and practice.
