MDG 7: Ensure Environmental
Sustainability
Protecting biodiversity, forests,
fisheries, soil and water is an overarching objective of CGIAR
research. Agriculture is the primary interface connecting human
beings and the environment and accounts for the bulk of human
exploitation of such natural resources as land and water.
Agricultural activities - including habitat encroachment through
agricultural expansion, and freshwater diversion and the mining of
aquifers for irrigation - have transformed between a third and half
of the earth's land surface. Current practices threaten
long-term sustainability. Sustainable development critically
requires shrinking agriculture's large and growing ecological
footprint. Biodiversity is being lost at unprecedented rates, and
25 biodiversity hotspots occupying only 1.4 percent of the earth
support more than 60 percent of the planet's plant and animal
species. Protecting such hotspots from encroachment requires the
sustainable intensification of agriculture, allowing more yield per
unit of land and of water through improved cultivars, techniques,
inputs, infrastructure, incentives and institutional support.
Research Results:
Eleven CGIAR genebanks together
hold the world's largest collection of crop biodiversity, with
over 600,000 samples. These seed samples represent a 10th of the
world's unique samples of major food crops, with the emphasis
on farmers' traditional varieties. Of the more than 1 million
CGIAR samples exchanged over the past decade, over 80 percent went
to universities and national agricultural research systems in
developing countries
Fertilizer tree systems can capture 100
kilograms of atmospheric nitrogen per hectare per year and convert
it into forms useful to crops. They allow poor farmers to double or
triple their maize yields without buying expensive nitrogen
fertilizer.
