This paper addresses the broad question ofwhere to locate authority for tropical biodiversity conservation considering: (1) community-based natural research management (CBNRM) overreaches the indisputable place of local communities in tropical conservation efforts; (2) the most promise for...

Ecotourism, bioprospecting and non-timber product marketing have been promoted recently as market-based instruments for environment al protection, but without sound understanding of the resulting net conservation effects. We present evidence on the local effects of recent argan oil...

This paper explores whether bioprospecting can reasonably be expected to change rural incentives to conserve tropical ecosystems. Bioprospecting advocates posit that the prospect of discovery ofbiota of immense commercial worth offers an avenue to increase the valuation of nature and...

This paper reports results from a study of resource degradation and conservation behavior of peasant households in a degraded part of the Ethiopian highlands. Peasant households' choice of conservation technologies is modeled as a two-stage process: recognition of the erosion problem, and...

In a departure from past contingent valuation research of groundwater quality, this paper estimates a damage function for nitrate exposures based on actual water test results of individual wells. From the perspective of reliability, it is argued that such a full information approach more closely...

Geologic estimates of remaining global petroleum resources place about 50% in the Persian Gulf. Production costs are estimated at $5 per barrel there, and $15 per barrel in the North Sea and Alaska. Using mathematical methods derived from depletion theory is utilized to explain the $15-$20 per...
