Solar-powered irrigation systems have shown the most impact in various specific regions, particularly in low- and middle-income countries with significant agricultural needs and water access challenges.
Key Regions with Significant Impact
1. The Sahel Region, West Africa
- The Sahel, a semi-arid region spanning countries like Burkina Faso, Senegal, and Niger, shows enormous potential for solar-powered irrigation to unlock vast groundwater reserves critical for agricultural growth and food security.
- The Food and Agriculture Organization (FAO) highlights that over 80% of the land in Senegal, for example, is highly suitable for solar irrigation using groundwater resources. This region benefits from abundant solar energy and untapped underground water, which solar-powered pumps can access affordably compared to diesel-powered systems. This can help mitigate drought and hunger affecting over 38 million people in the Sahel and West Africa.
2. Sub-Saharan Africa (including Mali, Ethiopia, Senegal, Ivory Coast)
- Studies have identified rural districts in southern Mali (such as Bougouni and Koutiala) as suitable for solar-based irrigation, with about one-fifth of the landscape in these districts compatible with solar irrigation installations. Solar irrigation has contributed to improving socio-economic status and reducing vulnerabilities of small-scale farmers in these areas.
- Other countries like Ethiopia, Senegal, and Ivory Coast have also undertaken efforts to implement solar-based irrigation systems that aid rural agricultural development and climate-smart farming practices.
3. Arid and Semi-Arid Regions in the Middle East and South Asia (Yemen, Afghanistan)
- In Yemen’s central Sana’a Basin, solar-powered groundwater pumps have become an essential energy source for irrigation, with more than 30% of farmers using solar pumps. This rapid adoption is anticipated to completely replace fossil-fuel pumps by 2028, though it is accompanied by concerns of groundwater depletion due to intensive pumping.
- Similarly, in Afghanistan’s desert province of Helmand, tens of thousands of opium farmers have shifted from ineffective canal irrigation to solar groundwater pumping, causing significant declines in water table levels.
Summary Table of Impactful Regions and Key Features
| Region | Countries | Impact Highlights | Challenges/Notes |
|---|---|---|---|
| Sahel (West Africa) | Burkina Faso, Senegal, Niger | Unlocking groundwater, high suitability, drought mitigation | Hyper-arid zones present in parts |
| Sub-Saharan Africa | Mali, Ethiopia, Senegal, Ivory Coast | Improved socio-economic status, suitable landscapes identified | Requires agronomic and financial support |
| Middle East & South Asia | Yemen, Afghanistan | Rapid adoption replacing fossil fuels, groundwater depletion | Risk of over-extraction of groundwater |
Conclusion
Solar-powered irrigation systems have demonstrated strong impacts mainly in the Sahel region of West Africa, parts of Sub-Saharan Africa, and arid regions in the Middle East and South Asia. They offer a low-cost, sustainable alternative to diesel pumps, enabling farmers in water-scarce, off-grid areas to irrigate crops more efficiently. However, their rapid adoption brings risks such as groundwater depletion, underscoring the need for integrated water management and sustainable use policies.
