In the arid landscapes of Bolivia, communities once facing depopulation and agricultural collapse due to chronic water scarcity are now experiencing a remarkable revitalization. The catalyst for this change is solar energy, which is powering innovative irrigation systems that restore livelihoods, enhance food security, and are starting to reverse the trend of urban migration.
The community of Huatapampa in the Tito Yupanqui municipality exemplifies this transformation. Once a thriving village of 120 families, its population dwindled to just 30 as residents left in search of opportunities. “The lack of livelihoods and food forced our people, especially the young, to move to the city,” explains Liduvina Pucho Ulo, president of the Sumaj Qamaña farming cooperative. Widespread crop loss and soil degradation left few reasons to stay.
A pivotal partnership between Practical Action, Green Empowerment, and Christadelphian Meal a Day introduced a solar-powered irrigation system that has fundamentally changed the community’s fortunes. This technology extends the productive agricultural cycle from June to December, enabling farmers to increase yields and diversify their crops. Initially launched with 12 families, the system’s success has led to its expansion, now serving 80% of Huatapampa’s population and benefiting nearby markets.
The water crisis is not unique to Huatapampa. Nearby, the municipality of Huarina faces similar threats despite its proximity to a large lake. “Our ancestors once described these springs as large and essential for the population. However, due to climate change and pollution, this vital resource is diminishing,” said Wilson Mamani, Mayor of Huarina. This decline has spurred migration and increased poverty. In response, Practical Action is working with the municipal government to implement a similar solar-powered water system to improve the quality of life.
The success of these projects has created a blueprint for regional climate adaptation. Under the “Solar Empowerment for Smallholder Farmers in Bolivia” project, funded by the EKOenergy ecolabel and Kilburn + Strode, these solutions are being scaled up. Municipalities across the Katari Basin, including Tito Yupanqui, Calamarca, San Andrés de Machaca, and Pucarani, are adopting solar irrigation to support an estimated 280 households.
By collaborating with local authorities, organizations like Practical Action are equipping Bolivian farmers with climate-resilient water solutions. These initiatives go beyond infrastructure; they build local capacity for sustainable agriculture and natural resource conservation. The shift to solar power in Bolivia demonstrates how targeted renewable energy projects can create lasting economic and social benefits, empowering smallholder farmers to build a more secure and prosperous future.
