Cochabamba will endure prolonged periods of drought in the next 10 years due to the lack of rain, due to the El Niño phenomenon, according to experts. The lack of rainfall will mainly affect the southern cone region, where the flow of some rivers has already been reduced by up to 10 percent, according to specialists.

The forecasts were shared yesterday at the launch of the Departmental Water Summit, which seeks to coordinate actions to face the climate crisis and drought. The activity was organized by the Government and the international organization Water For People.

The researcher and representative of the Bolivian Association of Sanitary Engineering, Mauricio Villazón, indicated that, in the next decade, the department “will probably have significant droughts” and that the lack of rain will cause “variability” in the climate.

“Currently, we are semi-arid due to the rainfall we have, but we will become more arid in the inter-Andean valleys,” he said.

The expert made the projections through the analysis of the amount of annual rainfall reported by the National Meteorology and Hydrology Service (Senamhi) since 1950.

He explained that El Niño hit the department with severe droughts in 1983, in 1994, in 1997 and in 2015.

He said the situation in 2023 could be worsened by climate change, the effects of gases and the repercussions of global warming.

Meanwhile, the researcher and associate of the Stockholm Environment Institute (SEI), Gustavo Ayala, indicated that in the update of the country’s water balance it was detected that in Cochabamba the flow of the Mizque River, in the southern cone, has decreased.

“This is a challenge for people who are working to size infrastructure projects such as dams, irrigation systems, because eventually you have to enter those areas very carefully so as not to overestimate the flow,” he pointed out.

Governor Humberto Sánchez reported that, to date, 19 municipalities have declared themselves in emergency and three in disaster due to the lack of water for consumption and irrigation. For this reason, the possibility of a departmental emergency declaration is being analyzed.

Among the alternatives to alleviate the drought, the Government proposed resuming the cloud bombing proposal, but the technical aspects are still being debated, according to the Director of Irrigation, Ronald Equilea.

Alternatives to mitigate water scarcity will be discussed at the Water Summit, which will take place on September 28 and 29.

The manager of the Agricultural Chamber, Rolando Morales, commented that the Departmental Legislative Assembly was requested to declare a disaster due to drought, in order to channel economic resources to deal with projects and thus guarantee access to water resources for the population.
