Land management is one of the key issues facing the planet in the 21st century. As a result of climate change droughts are becoming longer and more intense and severe flooding is getting worse. Land degradation due to human activity and extreme weather is increasing the spread of deserts, reducing biodiversity, making it harder for farmers to produce crops and increasing water scarcity.

The hunt for solutions is pressing, and growing evidence suggests there’s a role to be played by the humble bund – a simple structure that’s been used by farmers for thousands of years.
