Ecowatch has a way, adapted from native people, who have always had to eat year-round:
From vertical farms to solar-powered “farms from a box,” we’ve seen how farming technology has grown leaps and bounds in recent years. But for those who prefer something a little more rustic, growing food from a hole in the ground is as low-tech as you can get.
A walipini, meaning “place of warmth” from the Amaraya Indian language, is an underground greenhouse with a transparent (usually plastic) covering that stays warm by passively soaking up the sun’s heat and absorbing the earth’s thermal energy.
Fruits and vegetables can be grown year-round, making it ideal for communities in colder locations that can’t usually grow their own fresh and local produce during certain parts of the year.
The farming method isn’t exactly new. Walipinis have been used in South and Central America for decades, including one that can grow bananas at 14,000 feet in the Andes.
The technique was notably adopted by The Benson Institute, a worldwide food security program of the Mormon church. According to The Plaid Zebra, the Benson Institute and its team of volunteers built a community-sized 74-feet-by-20-feet walipini in La Paz, Bolivia for around a mere $300.
