With growing pressure on water resources, universal access to drinking water and sustainable water management represent major challenges to our societies. Rainwater is a resource that can be harvested with minimal environmental impact, to ensure the human right to water is fulfilled.
The development of industrialized countries and this need to ensure water needs of populations and of the economy, was designed on a short-term logic, disregarding balances and ecosystems, using brutal extractive logics with often little consideration of long-term impacts. This approach widespread and it is often found in developing countries and even in non-governmental organisations or development aid projects. Harvesting this resource at any cost has serious consequences on aquifers and creates long-term vulnerabilities for future generations.
Water resources are modified by variations in land use, temperature and precipitation. Population growth, urbanization, ecosystem degradation and depletion of aquifers have negative effects on drinking water supply, biodiversity and agricultural production.
Harvesting rainwater at the catchment level, in soils, vegetation, and reservoirs, offers a means of addressing domestic, agricultural, industrial and ecosystemic water needs, while promoting sustainable resource management behaviours. Cultivating landscapes as living sponges that retain water substantially relieves demand for groundwater resources. This allows aquifers to recharge.
Collecting rainwater affords a triple gain: mitigating flood risks, storing water for use during periods of drought, and optimizing the use of this resource. All three benefits increase the resilience of rural and urban communities as they adapt to the extreme weather events associated with climate change.
In many countries where we work, women and girls bear the responsibility of collecting water (30 - 50 liters per day), to meet their families daily needs.
This requires women to rise early and walk to a local spring, well, or river, located on average 2 - 3 km from their homes. They must then fill 15 - 20 l cans, travelling back and forth to collect the required volume of water.
This chore can lead women and girls to suffer from headaches, back pain, and fatigue, which often results in girl's dropping out of school, and women's social isolation.
Thus, women lose productive time, which could be used to develop an income-generating activity, for their education and caring for their children. Additionally, when collecting water, women are at risk of injury, and seeking water before sunrise exposes them to greater risk of sexual assault. Often, without the ability to influence community-level decisions, such women cannot change the management and planning of community infrastructure.

The optimization of rainwater (which to date is not managed strategically) is an efficient and innovative response to address the challenges of water scarcity, droughts and floods and strengthen the resilience of communities and communities. ecosystems, natural disasters and climate change.
Rainwater management addresses the Sustainable Development Goals (SDGs 2, 3, 5, 6, 10, 13 and 17). We implement these goals through international development projects, by supporting local municipalities and local authorities, and through projects that raise local awareness of the socio-environmental benefits of rainwater harvesting.
Climate change requires us to rethink our management methods and practices. This project aims to build community resilience by combining better management of water resources, trees and soil.

The "Emergency Rain" project aims to provide access to clean water and restore dignity for those who have nothing, the forgotten from water services, who live on the outskirts of our cities and have to fight every day to access even water for drinking.
The objective of this workshop is to bring school children to become aware of their environment, and to be able to implement durable, sustainable solutions in their city.
