Nigerian Farmers Cut Fuel Costs and Boost Yields with Solar-Powered Irrigation

Sack farming—growing crops in soil-filled recycled bags within household compounds—has enabled farmers in Kwara State, Nigeria, to overcome climate challenges by producing vegetables and tubers that significantly reduce household food expenses, generate supplementary income from excess harvests, and provide up to 80% crop success rates.

An AI-powered underwater sensor system developed by KMFRI and ShoShin Innovation Hub detects dangerous drops in dissolved oxygen in Lake Victoria and sends SMS alerts to fish farmers. This enabled them to move their cages in time and successfully averting a mass fish kill in February 2026 that would have threatened hundreds of tilapia cages at Dunga Beach.

Solar-powered cold storage units operated through Farmer Producer Organizations in India have reduced post-harvest losses from as high as one-third of crops to minimal levels. This enables smallholder farmers to save on storage and transportation costs while gaining control over when to sell their produce at better prices.

After insurgents cut off the village of Maiduguri from the power grid, residents started switching to solar energy as a way to power their appliances. For many, using the solar kits have reduced their energy expenses, but, at the same time, they also require more battery maintenance and the upfront cost can be expensive. “It has reduced daily expenses in terms of fueling generators and monthly servicing,” says one resident. “All these things are off my neck.”

Solar-powered irrigation allows women in Gella to farm during the dry season, enabling multiple harvests per year that provide food security, income, and social connection while increasing women's economic agency in a post-conflict community.

A Ukrainian community transformed a rural high school biology classroom into a fully-equipped research lab with field stations and youth training programs, enabling students to conduct real scientific experiments and inspiring career choices in environmental fields. The broader community's relationship with nature has also shifted from resource extraction to ecosystem stewardship.

Rewilding Romania, in partnership with WWF Romania and the EU's LIFE Programme, has reintroduced over 100 European bison into the Southern Carpathian Mountains since 2012. Since then, a self-sustaining wild population of 250+ animals has grown, leading to measurable ecological and economic benefits for surrounding communities.

Women farmers in Bihar are installing and operating solar irrigation pumps and selling water to neighboring fields—cutting irrigation costs (often versus diesel), improving agricultural output, and generating a steady income.

Solar-powered dryers are enabling women in India to produce and sell dried fish at markets in a manner that is healthier for them and the environment. It's also proving economically profitable.

With funding and support from the Heritage Foundation Pakistan, a remote, off-grid village installed a solar energy system that supplies residents with free power and has improved their quality of life.
