Market mechanisms for forest environmental services are increasingly used for promoting environmental conservation, and their impacts on development are of considerable interest. In Costa Rica a national scheme of Payment for Environmental Services (PSA) rewards landowners for the services provided by different forest land-uses. We evaluated the impacts of reforestation under the PSA on local development in the North of the country.
Regulating industrial forest concessions in Central Africa and South America
Tropical countries face special specific problems in implementing sustainable forest management (SFM). In many countries, questions are raised on whether tropical forests should be publicly, commonly or privately owned and managed in order to enhance sustainability. Other debates also focus on whether small-scale enterprises are better positioned than large-scale industrial concessions to reduce poverty and attain sustainable management.
Property rights, land conflicts and deforestation in the Eastern Amazon
In the Brazilian Amazon, insecure property rights are among the main causes of land conflicts and deforestation. Through an in-depth empirical case study in Maranhao in the Eastern Amazon, this research analyzes how distorted agrarian, forest and environmental policies, laws and regulations originated insecure property rights not only over land, but also over timber, which allied to social and political factors, such as uneven distribution of land and strong organization of landless peasants, led to land conflicts and deforestation.
Estimating the effects of adjacency and green-up constraints on landowners of different sizes and spatial arrangements located in the southeastern U.S
The maximum clearcut size and green-up period is important for land managers adhering to voluntary and regulatory guidelines. Therefore the impact of actual and hypothetical clearcut size restrictions is a concern for forest landowners who manage land and intend to practice forestry for profit. In this research, the effect of a 97.1 ha (240 ac) clearcut size constraint with a green-up period of 2-yrs is assessed for forest landowners with different forest land sizes, ownership patterns, and age class distributions.
Assessing the impact of changes in landuse and management practices on the diffuse pollution and retention of nitrate in a riparian floodplain
In many European lowland rivers and riparian floodplains diffuse nutrient pollution is causing a major risk for the surface waters and groundwater to not achieve a good status as demanded by the European Water Framework Directive. In order to delimit the impact of diffuse nutrient pollution substantial and often controversial changes in landuse and management are under discussion.
