Water
Village well
A village well is a shallow masonry well (10-40 m) dug at the heart of a village, providing drinking water for approximately 500 people with a lifespan of ~30 years. It is managed by a local committee (COGES) trained to ensure maintenance.
Pastoral well
A pastoral well is a deep cement well (40-80 m), exclusively for watering nomadic livestock (camels, goats, donkeys). It secures transhumance routes in desert areas.
Vegetable garden well
A vegetable garden well is dedicated to irrigating an oasis garden, typically managed by a women's cooperative. It supplies 0.5 to 1 hectare of crops (tomatoes, onions, cabbage, lettuce).
Solar borehole
A solar borehole is a deep borehole (typically > 80 m) equipped with a submerged pump powered by photovoltaic panels. It is the most sustainable solution for high flow rates in desert areas without an electrical grid.
SDG 6
Sustainable Development Goal 6 — Clean water and sanitation
SDG 6 is the 6th of the 17 Sustainable Development Goals adopted by the UN in 2015. It aims to ensure access to water and sanitation for all by 2030, managed sustainably. Les Puits du Désert's actions directly contribute to this goal in Niger.
WASH
Water, Sanitation and Hygiene
WASH (Water, Sanitation and Hygiene) is the acronym used in the development and humanitarian sector to refer to the water-sanitation-hygiene combination. It is the conceptual framework of funders (AFD, UNICEF, World Bank) for water access programs. Les Puits du Désert operates within this approach.
NGO
COGES
Water Management Committee
The COGES (Water Management Committee) is a community village structure that manages and maintains a water point (village well) after its construction. Composed of locally elected members, it collects fees, funds maintenance, and arbitrates usage. It is the condition for post-project autonomy.
NGO Tidène
Tidène — Nigerien operational partner
Tidène is a Nigerien NGO based in Agadez, created in 2004 by Mohamed Ixa (President) and co-founded with Christel Pernet (LPDD). It is the sole operational partner of Les Puits du Désert in Niger: 100% Nigerien, natives of the region, no expatriates. It executes all field projects.
Geography
Agadez Region
The Agadez region is the largest in Niger: 667,799 km² (equivalent to the area of metropolitan France), 714,509 inhabitants (INS 2024). It is the operating area of Les Puits du Désert in Niger, including the Tidène valley, the Aïr massif and the city of Agadez.
Tidène Valley
The Tidène Valley is a valley of the Aïr massif, located in the Agadez region of northern Niger, about 90 km north of the city of Agadez. It is home to about 16,000 inhabitants, mostly nomadic Tuareg. It is the historic starting area of Les Puits du Désert in 2004 — since then, the action has expanded to the entire Agadez region.
Agadez
Agadez is a historic city in northern Niger, capital of the Agadez region and gateway to the Ténéré desert. A UNESCO World Heritage site, it is the administrative and economic center of the operating area of Les Puits du Désert (Tidène valley, located 90 km further north).
Tuareg
The Tuareg (or Kel Tamasheq) are a Berber nomadic people of the central Sahara, mainly present in Niger, Mali, Algeria, Libya and Burkina Faso. Their language is Tamasheq. The populations benefiting from Les Puits du Désert are overwhelmingly Tuareg.
