- Good morning. I am Here to present on behalf of the Institute of Hydrology, Meteorology and Environmental Studies and the University of applied Sciences, the Protocol to identify and Assess soil degradation by erosion in Colombia
- First I want to show you that Colombia is located in the North of South America, being an equatorial and tropical land, with more than 1 million square Km of land, and as many other countries soil erosion is the main degradation problem.
- This slide shows the national institutions and international agreements regarding soil and land issues. Under the Ministry of Environment, the IDEAM is in charge with soil and land quality assessment at National level, from which a National Soil Committee has been created, and Soil National Policy has been establish.
- This policy aims to protect soils in a sustainable way in order to increase soil quality, this means soil degradation problems must de known.
