Fundamentals of Ecological Restoration of Tropical Forests
Summary
The Cali River Watershed provides 20% of the water that is consumed in the city of Cali (one of the largest in Colombia). In recent decades, the basin has undergone rapid transformations in the landscape and land uses. In particular, the degradation of its forested areas threatens important ecosystem services provided to local communities and human populations on a regional scale, including the regulation of water quality and quantity and hydropower production.
In order to reduce environmental degradation within the watershed and protect the ecosystem services provided by the forests located in it, local organizations have proposed an incentive scheme that supports conservation actions to conserve and the restoration of ecosystems and water sources in the region. The fulfillment of the objectives of the scheme depends largely on training leaders and managers of environmental institutions and community groups on the knowledge and skills relevant to the local context of the watershed.
This course was designed to introduce participants to the principles of ecology and forest disturbances, and the fundamentals of ecological restoration. It also has the general goal of providing them with the necessary tools to understand the impact of the ecological conditions and disturbance history of the site, in designing restoration strategies appropriate to the particularities of the Watershed.
