TL;DR: It is concluded that low-shade agroforestry provides the best available compromise between economic forces and ecological needs, and Certification schemes for shade-grown crops may provide a market-based mechanism to slow down current intensification trends.

TL;DR: In this paper, the applicability of stated preference methods for the valuation of ecosystem functions is a matter of debate, and the authors argue that the recognition of this principle is the key also for the application of stated preferences in the context of environmental valuation.

TL;DR: In this paper, the surface fractal dimension of the pore-solid interface was measured by fitting two straight lines to the log-log plot and finding a crossover point at a scale of about 14 μm, forming the border between textural and structural fractality.

TL;DR: In this article, the authors used a spatially explicit multinomial logit model to analyze the determinants of each of these proximate causes of deforestation between 1992 and 2004 and found that the largest share of deforestation is attributable to the expansion of mechanized agriculture, followed by cattle ranching and small-scale agriculture.

TL;DR: In this article, the authors highlight the critical issue of rainforest preservation from an interdisciplinary perspective, comprising input from scientists in socio-economic, biological, geographical, agrarian and forestry disciplines.
