This also presents people in the Andes with major new challenges. While smallholder households could still count on five to six months of rain 20 years ago, today the figure is just four to five months.<\/p>\n\n\n\n<p>Glaciers as water sources are also declining drastically. According to the authorities in Bolivia and Peru, the glacier retreat in the project region of the departments of Cusco and Puno (Peru) and La Paz (Bolivia) is between 70 and 90 percent. Important rivers are thus losing their most important water reserves and carry little water in the dry season, which makes supply and agriculture more difficult.<\/p>\n\n\n\n<p>There is a great need for action, as over 90 percent of smallholder farming families in these departments have no technical irrigation infrastructure. They are dependent on acquiring new knowledge and methods in the field of water management and working with micro-irrigation methods. The Lake Titicaca region in particular is facing a serious crisis that is jeopardizing the water supply for almost three million people in Bolivia and Peru. A large part of the population is of indigenous origin. Aymaras and Quechuas are particularly well represented.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Project goals<\/h2>\n\n\n\n<p>Together with its partner organizations, Missi-on 21 supports smallholder households in acquiring knowledge and skills in the field of water management and in setting up water retention basins and micro-irrigation systems. Water harvesting strategies such as reforestation and the planting of Andean grasses and mosses are also intended to increase the water storage capacity of the surrounding ecosystems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Target group<\/h2>\n\n\n\n<p>The activities are mainly aimed at smallholder indigenous communities in rural areas. Women play an important leadership role, as they are permanently present on the ground and play a key role in agriculture. However, the educational programs and all project activities relating to water extraction are open to all interested parties who wish to participate and expand their knowledge.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Activities<\/h2>\n\n\n\n<p>- Imparting skills and knowledge in the field of water management<br>- Construction of water retention basins and natural seepage pits on slopes<br>- Reforestation and planting of shrubs along strategic areas such as water source areas, river beds and wetlands<br>- Installation of micro-irrigation systems for the cultivation of food crops<br>- Imparting knowledge for dealing with enforcement authorities and about basic rights in water use<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Project progress<\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Prodiasure<\/strong><\/h4>\n\n\n\n<p>Unsere Partnerorganisation unterst\u00fctzte 2025 die Wasserbeh\u00f6rden auf Gemeindeebene, die hier eine f\u00fchrende Rolle bei der Umsetzung von Massnahmen zur Wassergewinnung und zur Anpassung an die Folgen des Klimawandels spielten. Dazu geh\u00f6ren Aufforstungskampagnen und Baumassnahmen: Versickerungsgr\u00e4ben, Terrassen und R\u00fcckhaltebecken. So wurde etwa ein rundes Betonbecken mit einem Fassungsverm\u00f6gen von 70.000 Litern Wasser gebaut. Das Wasser wird von den Familien f\u00fcr die agrar\u00f6kologische Produktion und auch f\u00fcr den allt\u00e4glichen Verbrauch genutzt.<\/p>\n\n\n\n<p>In der Gemeinde Copacati haben Aymara-Frauen eine f\u00fchrende Rolle bei den Massnahmen zum integrierten Wassermanagement \u00fcbernommen und sind rege beteiligt, Wassergewinnungspraktiken in ihrer Gemeinde zu verbreiten und umzusetzen. Zudem sind sie aktive Mitglieder des Netzwerks der Wasserbeobachterinnen und des Titicacasees \u2013 und stellen in diesem Netzwerk auch die Pr\u00e4sidentin, welche die Pflege des Titicacasees leitet und f\u00f6rdert.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Fundaci\u00f3n Machaqa Amawta<\/strong><\/h4>\n\n\n\n<p>Die Stiftung FMA unterst\u00fctzte 2025 die Bev\u00f6lkerung der Gemeinde Macamaca dabei, ein Bew\u00e4sserungssystem einzurichten und laufend zu verbessern. Dadurch erhielten rund 370 Personen Zugang zu Wasser. Erg\u00e4nzend wurde der Stand an technischen Kenntnissen in der Gemeinde erhoben und die Projektteilnehmenden konnten sich zu nachhaltigem Verhalten im Verbrauch von Wasser und in der Wiederaufforstung schulen. Wichtig waren auch soziale Weiterbildungen: f\u00fcr eine Wasserbewirtschaftung, die durch gemeinsam getroffene Vereinbarungen und Entscheide getragen wird.<\/p>\n\n\n\n<p>Diese Verbesserung des Bew\u00e4sserungssystems im Rahmen eines gemeinschaftlichen Prozesses verbesserte auch die Bedingungen f\u00fcr die Produktion von Nahrungsmitteln und zur Schaffung von Einkommen. In diesem Prozess wurden Frauen und M\u00e4nner als gleichberechtigte Akteure bei der Entwicklung von L\u00f6sungen f\u00fcr das Gemeinwohl anerkannt. Durch die Weiterbildung st\u00e4rkte die Gemeinde zudem das Bewusstsein daf\u00fcr, wie wichtig es ist, die nat\u00fcrlichen Quellen im Einzugsgebiet des Titicacasees zu sch\u00fctzen. Denn die Quellen bilden neues Grundwasser und speisen den See mit frischem Wasser.<\/p>\n\n\n\n<p><strong>This film by our partner organization IDECA is about coping with climate change in the
