Irrigation in Colombia has been an integral part of Colombia's agricultural and rural development in the 20th Century. Public investment in irrigation has been especially prominent in the first half of the Century. During the second half, largely driven by fiscal shortages and a common inability to raise sufficient revenues from collection of water charges, the Colombian government adopted a program to devolve irrigation management responsibility to water users associations. Irrigation management transfer has occurred only partially in Colombia, as the government has maintained strong managerial tasks in certain irrigation districts.

Colombia has approximately 900,000 hectares of irrigated agriculture, mostly located in the warm center, Magdalena, Cauca and Tolima Valleys, and the northeast near Venezuela’s border and along the Caribbean coast. Approximately, 90% of the agricultural land is irrigated through gravity irrigation systems. According to the Food and Agriculture Organization (FAO), 62% of the functional irrigable land in Colombia has been developed and managed by the private sector. Only 38% was developed by the public sector. FAO estimates that the private sector invested on average US$19 million annually during the period 1991–1997. Colombia has a considerable potential to expand land under irrigation due to high rainfall and fertile volcanic soil creating conditions favorable for a wide range of crops.

Efficiency of irrigation systems is in general very low in the country contributing to soil salinization and water erosion. In addition, agricultural runoff including chemicals from fertilizers and pesticides are taking an increasing toll on Colombian ecosystems. According to the first national communication to the United Nations Framework Convention on Climate Change, Colombia is highly vulnerable to the impacts of climate change, especially highland Andean ecosystems. Colombian Government is in the process of implementing an Integrated National Adaptation Project focused on defining and implementing policy options to meet the anticipated impacts of climate change.
