Although sustainable tourism represents a positive approach for community development, its practical implementation is challenging. Given that there is no one institutional recipe that fits all cases, it is necessary to cumulate knowledge from lessons from isolated cases where a combination of institutional arrangements and context-specific characteristics showed to be - or not - successful for tourism management.

New methods of fiber pre-processing and cellulosic fermentation may allow production of isoparaffinic kerosene, a bio-based jet fuel, from abundant post-logging biomass residues in western Oregon and Washington, USA. Since production of these residues is characterized by complex spatial patterns that can shift markedly over time, and since residues may comprise roughly one-fifth of annual refinery operating costs, careful evaluation of residue supply (quantity/price) behavior is warranted.

Despite the growing body of evidence showing benefits and values of recreational ecosystem services, in sub-Saharan Africa, such evidence is extremely limited. This is problematic, and may perhaps explain their current poor condition. This study uses a random survey of households residing in Dar es Salaam to value the benefits of urban parks. The estimation is based on random utility framework where different models, with varying assumptions on preference and scale heterogeneity, are estimated.
