The nature of economic development and the economic development of nature

Contemporary models of growth and development are founded on a category error: they ignore nature as a form of productive capital. Using as backdrop two recent books on the Indian economy that are representative of the prevailing orthodoxy, I review and in part extend an emerging literature that integrates development and environmental thinking. Contributors to the literature have reworked the economics of the household, communities, and other non-market institutions, reframed national accounting, reconstructed the theory of macro-economic development and public and trade policy, and revised the theory of collective action. In this paper I focus on a small part of the literature: economic evaluation. I develop the notion of sustainable development and construct a unified language for sustainability and policy analyses. I show that by economic growth we should mean growth in wealth - which is the social worth of an economy's entire set of capital assets - not growth in GDP nor the many ad hoc indicators of human development that have been proposed in recent years. The concept of wealth invites us to extend the notion of capital assets and the idea of investment well beyond conventional usage. I also show that by sustainable development we should mean development in which wealth (per head) adjusted for its distribution does not decline. This has radical implications for the way national accounts are prepared and interpreted. I then provide an account of a recent publication that has put the theory to work by studying the composition of wealth accumulation in contemporary India. Although much attention was given by the study's authors to the measurement of natural capital, due to a paucity of data the value of natural capital is acknowledged by them to be under-estimated, in all probability by a large margin. The study reveals that the entire architecture of contemporary development thinking is stacked against nature. These are still early days in the measurement of the wealth of nations, but both theory and the few empirical studies we now have at our disposal should substantially alter the way we interpret the progress and regress of nations

How sustainable is participatory watershed development in India?

Watershed conservation is widely recognized as a major strategy for rural development throughout the developing world. In India, the apparent success of participatory approaches to watershed development resulted in a decentralization of project planning, implementation, and management to local communities at the village scale. We explore the effectiveness of this so-called community-based approach in achieving sustainable soil and water conservation in four semi-arid regions in India, and analyze what factors explain project success. We confirm the result of earlier studies that participatory approaches are more effective in establishing soil and water conservation in the short run. However, our main result is that investments in community organization fail to ensure household commitment to maintenance in the longer term. Without better returns to investment in soil and water conservation and without local institutions to coordinate investment in the long run, the sustainability of participatory watershed management is seriously threatened.
