Today, as a result of the
agricultural expansion, the
growth of populations and
misuse of agricultural technologies, new direct and indirect drivers of change have increased pressures on biodiversity and natural resources, including water, land and nutrients.
Over the past 50 years, agricultural expansion into tropical and sub-tropical regions has substantially reduced levels of biodiversity. At the same time,
food production has
increased by
160% from 1961 to 2003. Tradeoffs for an increase in food production has
contributed to a
decline in other ecosystem services, with
60% of them being degraded.
The resulting loss of biodiversity from these drivers of change and an associated decline in ecosystem services has significant consequences for the health and well being of all species on Earth. The challenge for farmers and humanity as a whole lies in ensuring
food security, adequate
nutrition, and stable
livelihoods for the population of the world. Creating
sustainably managed agricultural systems is essential.
