Maintaining or improving the productive capacity of land
requires a move towards land degradation neutrality.
This is a matter of preserving or enhancing the ability of
land resources to support ecosystem functions and services.
Sustainable management of soil, water and biodiversity
can help close yield gaps, increase the resilience of land,
and thus support the people who depend on it for their
livelihoods. This will come at a cost, but the cost of action
or prevention is always smaller than the cost of inaction.
