This article develops a framework to analyze the impacts on resource development of efficient management practices that account for possible resource conserving technological changes. Compared with the traditional management practice ignoring these changes, efficient management may not delay or reduce resource development, depending on the level of the changes. Under efficient management, a hig...

This paper develops a framework to analyze the impacts on resource development of e cient management practices that account for possible resource conserving technological, institutional and taste changes. Compared with traditional resource management that ignores these future possibilities, e cient management may not delay or reduce resource development. Under e cient management, higher probabi...

During the 1970s the building industry witnessed a focus on energy-conserving building materials sparked by oil-price increases; during the 1980s attention to building materials that reduced or omitted pollutants became important as a result of the "Sick Building Syndrome" or indoor air pollution. Now, in the 1990s, we are engaged with a more comprehensive definition of environmental materials ...

Many observers have conceptualised the link between rural poverty and environment as a ‘downward spiral’ with population growth and economic marginalisation leading to environmental degradation. Recent micro-scale empirical research challenges this model, showing striking heterogeneity in environmental management by the rural poor, their success in adapting to environmental change and the effic...

the evidence from experiences and projects have revealed that favourable policy environment, resource conserving technologies, enabling external institutions, and local institutions and groups are the components and the preconditions needed for the successful implementation of sustainable agriculture. in this context, the mission of government is providing an appropriate institutional environme...
