As the world's population grows, we must increasingly address the limited availability and use of natural resources such as water, soil and biodiversity. Structured land use planning that balances interests helps to keep natural resources permanently available and thus prevent poverty and conflicts resulting from resource scarcity. To permanently conserve soil, water, and biodiversity, sustainable land management practices must be more consistently disseminated. Degraded systems can be rehabilitated to some extent. A holistic understanding helps to realistically assess the value of the services ecosystems provide and to protect them as common goods.
