SUASTEGUI CRUZ, Sirilo. Strategies for water security in the face of changes in precipitation due to climate change effects. RIDE. Rev. Iberoam. Investig. Desarro. Educ [online]. 2021, vol.12, n.23, e029.  Epub 14-Fev-2022. ISSN 2007-7467.  https://doi.org/10.23913/ride.v12i23.1039.

Climate change negatively affects precipitation patterns, with brief periods of rainfall impacting ecosystems through drought and food production, hindering water supply in marginalized areas such as Las Animas, where the key to survival is based on the Agriculture. There are global circulation models such as the MPI ECHAM 5 and HadGEN1 and scenarios A2 and B2 that allow visualizing past and future rainy periods to anticipate changes and be able to generate strategies from local areas.

This research was quantitative, longitudinal-retrospective, non-experimental and explanatory, where precipitation data for the years 2015, 2016 and 2017 were found, as the most critical points (2015 and 2016), as well as the variations for 2030 and 2050 that indicate that precipitation will increase but with shorter periods, which will affect agriculture and generate water and food security problems in rural areas, where it is necessary to resort to annual community resilience mechanisms with improvements in catchment, conservation and water management.
