Application of Participatory Methods to Explore Changes in Land Use of a Tropical Dry Forest Basin

Tropical hydrographic basins have undergone significant land use change processes in recent decades and correspond to areas of high population growth and development of economic activities. This article explores the causes of land use change in a tropical dry forest watershed, taking the Canalete river basin as a case study. For this purpose, stakeholder analysis techniques and participatory methods were applied. The results showed that the main causes of land use change in pastures were associated with biophysical factors, while forestsshrubs and crops were associated with direct and subyacents socioeconomics factors respectively. The participatory mapping allowed obtaining a desired land use scenario for the year 2030, observing a decrease of more than 16.2 ha of pasture, compensated by an increase of almost 2.4 thousand ha of crops and 13.8 thousand ha of forests and shrubs. Similarly, the hydrological impact of changes in land use was observed, especially in terms of flooding.
