The Democratic Republic of Congo is a country with the most abundant water resources in Africa, the rainfall of an annual average of about 6,000 billion m3 is regular and abundant under an average of 1,545 mm / year but varies geographically from 800 mm to 1,800 mm depending on the season. The DR Congo also enjoys considerable autonomy in water, with 70% or 900 m3 / year of its natural renewable water resources estimated at 1,283 km3 / year from the different rainfall over the entire National Territory. The abundant water resources are intrinsically linked to its vast forests, which extend over more than 155.5 million hectares. The vast majority of the population of the Democratic Republic of Congo depends on sources supplied with water by dense forests (gallery forests and tropical forests) thus emphasizing the importance of forest ecosystem services for the supply in water for the benefit of local communities. However, the overall rate of deforestation at the national level perpetrated by the population itself remains relatively high, in all regions across the country, while reforestation initiatives are relatively low estimated at 0.2% / year. This phenomenon of deforestation has reached a high level today with cruising speed and directly threatens water sources by drying up and drought, and thus destroys animal habitat, makes the socio-economic life of local populations difficult, who can no longer harvest abundantly following the current adverse climatic conditions.
