Climate change likely to affect food production in the developing world, while industrialized countries could register gains in production, "said Jacques Diouf. The yield potential is likely to increase at higher latitudes, according to culture, when average increase of global temperature from 1 to 3 ° C.

The lower latitudes, especially in tropical regions to seasonal droughts, it probably will decline, including in the presence of small increases in temperature, which would accentuate the risk of hunger. The increased frequency of droughts and floods would have a negative impact on local production, especially in subsistence sectors at low latitude, "said Jacques Diouf.

As a result the Director of FAO recommends an adaptation to climate change in many ecosystems, including agro-ecosystems (crops, livestock and grassland), forests and wooded land, inland waters and coastal ecosystems and sailors. According to him, science and technology should be the spearhead of agricultural production over the next 30 years.

Most GM plants grown today were designed for their tolerance to herbicides and resistance to pests even if GMOs with specifics such as resistance to drought, extreme temperatures, acidity and salinity soil, are not yet a reality, he indiqué.Veiller that new biotechnologies are contributing to this goal, taking fully into account considerations of bio-security, socio-economics and ethics related to the use of some of these technologies remains a challenge for the entire scientific community.
