    Objective of study were to simulate size area of land use change in Phitsanulok province from 2552 to 2560 B.E., and decided agriculture area and forest area, and to be use as a guideline map for formulating the land use and forest conservation, In Phitsanulok province. Geographic Information System couples with CLUE-S model by Logistic Regression and Markov chain model were used to predict of future land use in Phitsanulok province.

    The humid tropics are exposed to an unprecedented modernisation of agriculture involving rapid and mixed land-use changes with contrasted environmental impacts. Afforestation is often mentioned as an unambiguous solution for restoring ecosystem services and enhancing biodiversity. One consequence of afforestation is the alteration of streamflow variability which controls habitats, water resources, and flood risks. We demonstrate that afforestation by tree planting or by natural forest regeneration can induce opposite hydrological changes.

In this study, two PES programmes operating in the municipality of Coatepec (Mexico) were evaluated to assess their effectiveness in protecting the region's endangered upland forests. Landsat satellite data were analysed to assess changes in forest cover before and after programme implementation using a difference-in-differences estimator.

Measuring the social impacts of protected areas is difficult because the effects cannot be isolated from other factors, given the nonrandom placement of protection.
