Water resources management in the Dominican Republic
With surface water resources of 20 billion m3 (BCM) per year, of which 12 BCM are groundwater recharge, water resources in the Dominican Republic (DR) could be considered abundant. But irregular spatial and seasonal distribution, coupled with high consumption in irrigation and urban water supply, translates into water scarcity. Rapid economic growth and increased urbanization have also affected environmental quality and placed strains on the DR’s water resources base. In addition, the DR is exposed to a number of natural hazards, such as hurricanes, storms, floods, Drought, earthquakes, and fires. Global climate change is expected to induce permanent climate shocks to the Caribbean region, which will likely impact the DR in the form of sea level rise, higher surface air and sea temperatures, extreme weather events (such as tropical storms and hurricanes), increased rainfall intensity (leading to both more frequent and severe flooding) and more frequent and more severe "El Niño-like" conditions.〔
Water resources management in the country, in particular water quality, quantity and Watershed management faces major challenges today. Despite of the lack of systematic data limiting an accurate and detailed assessment of the scope of the problems, there is a consensus that: (i) the overall poor quality of surface, groundwater and coastal water resources is the result of a lack of waste water management and agricultural run-off, causing health problems that disproportionally affect the poor; (ii) water scarcity is a regional problem resulting from poor demand management in irrigation, urban water supply and tourist infrastructure in drier regions; (iii) weak watershed management leads to soil erosion and amplifies the damage and frequency of flooding; and (iv) the overall lack of solid waste management pollutes water sources, causes disease and is a nuisance for inhabitants and visitors alike.〔

==Water management history and recent developments ==
During the end of the 19th Century and 20th Century, DR Government was one of the main investor in the country’s hydraulic infrastructure development. Primarily focused on developing irrigation infrastructure in the fist three quarters of the past century, DR government invested on canal networks and irrigation technology increasing the area under irrigation from 32,000 hectares (ha) in the 1940s to 132,000 ha in 1954. In 1965, the DR Government created the National Institute for the Development of Water Resources ((Instituto Nacional de Desarrollo de los Recursos Hidraulicos )– INDRHI) responsible for planning the sustainable use of water resources and associated resources, as well as designing, formulating, executing, monitoring and evaluating projects, programs and actions aimed at controlling and regulating superficial and groundwater. Over the last three decades, the DR government has decentralized a number of responsibilities in the water sector to other institutions, such as operation and maintenance of infrastructure and water fee collection to irrigation districts and regional water and sewer companies.〔 In addition, the electricity sector has been partially privatized in 1998-99, with hydropower remaining in public hands.
