Although water is an abundant resource, climate change is affecting the hydrological cycle. According to scenarios done by the Meteorological National Institute using PRECIS regional model, an important rainfall reduction with risk of droughts is expected on the Pacific Coast watersheds and the North, while an increase of rainfall with risk of floods is expected on the Caribbean Coast watersheds.

Costa Rica’s efforts to meet international agreements regarding mitigation and adaptation to climate change have been undeniable. The strong ecosystem conservation agenda of the country has significantly contributed to making climate actions more robust.
