TL;DR: The results show that, with appropriate empirical methods, conservation scientists and policy makers can better understand the relationships between human and natural systems and can use this to guide their attempts to protect critical ecosystem services.

TL;DR: Impacts of protected area systems on poverty in Costa Rica and Thailand are estimated and it is found that although communities near protected areas are indeed substantially poorer than national averages, an analysis based on comparison with appropriate controls does not support the hypothesis that these differences can be attributed to protected areas.

TL;DR: Pfaff et al. as mentioned in this paper investigated the relationship between park location and forest protection in Costa Rica and found that land characteristics cause differences in park impacts across Costa Rica, and that park location affects forest protection.

TL;DR: Issues on the two-way effects of agriculture and malaria are raised and recommended areas that require policy actions and further research are recommended.

TL;DR: In this paper, the authors focus on the feed milling industry, which serves as the link between maize and poultry, through a field assessment of feed millers in Ghana, and illustrate these linkages by means of a simple spatial market equilibrium model that ties together the three sectors of the poultry value chain: the primary inputs (maize and soybeans), intermediate inputs (feed), and final products (meat and eggs).
