Reversing environmental damage, restoring natural processes, and managing in a way that resources are not only conserved but are built up over time requires a fundamental shift in the way we think and work with nature and agriculture. It is a shift from from exploiting resources to actively designing and re-creating resource systems that can mimic nature in form and function.
This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends ensuring that a sound educational base is provided in natural systems, ecology and resource management.
