- Drylands, forage and livestock. From cattle, sheep, and goat herds, to horses and camels, drylands support large numbers of domestic animals, which become the source of meat, milk, wool, and leather products for humans.
- Drylands and biodiversity. Dryland species must adapt to an environment known for its variation in climate, both in terms of temperature and water availability.
- Drylands and carbon storage. Drylands, as an ecosystem with extensive surface area across the globe, have been suggested as a potential candidate for major carbon storage efforts.
