When we see the news reports on climate change, it often includes footage of factory chimneys and traffic jams. We may or may not realize that agriculture is also a key contributor. In fact, greenhouse gas (GHG) emissions from agri-food sectors — the systems by which our food is grown, produced and distributed — represent around 34 percent of total GHG emissions. But in hearing this, do we ever reflect on the fact that agriculture is also one of the areas most affected by climate change? Being both a source and a victim, the agricultural sector is in a unique position to offer solutions to this massive challenge.
With rising temperatures and unpredictable, extreme weather events, climate change is already threatening food security in many parts of the world.
In response, FAO is ramping up its work to help transform our agri-food systems to better respond to the climate crisis. One way of doing this is by spreading the use of green and climate-resilient agricultural techniques, which can help to reduce the negative impacts from the way our food is produced and reaches our plates.
Here are four examples of how FAO is helping farmers and food producers around the world to implement green and climate-resilient, innovative solutions:
1- Climate smart farming techniques in Sri Lanka
In Sri Lanka, the impact of climate change and environmental factors on agriculture is already quite clear. Fields are becoming unproductive due to heavy rains, excessive soil tillage and lack of nutrients. Reservoirs are silting up, affecting irrigation systems and hampering efficient use of water. All this leaves smallholders struggling to make a profit and often resorting to environmentally unsustainable farming methods to eke out a living from the land.
Through the Save and Grow project, supported by the German Federal Ministry of Food and Agriculture, FAO trained over 1 130 farmers to optimize the use of water, agricultural inputs and labour. The training has helped smallholders who grow the island’s main crops use 10 to 20 percent less water for irrigation, so they can store more for the next cropping season. By preparing their land early instead of waiting for reservoirs to fill up, they can irrigate 15 percent more land in the dry season. Saving water during the growing season, planting early and making better use of rainwater means they have more water left after the dry season. They also learned how to apply fertilizer more precisely, reducing the amount used by 27 percent.
2- Reforestation in Paraguay
In areas of eastern Paraguay, deforestation and forest degradation are widespread, and climate change makes communities who are dependent on family farming for food production and livelihoods increasingly vulnerable.
FAO is responding to the needs of these communities as the lead agency implementing an ongoing Green Climate Fund (GCF) project in the area, which focuses on 87 000 people, many from indigenous communities. Farmers will receive Environmental Conditional Cash Transfers in exchange for undertaking climate-sensitive, agroforestry projects. These initiatives include growing trees such as eucalyptus, citrus fruits and yerba mate plants and abandoning the practice of chopping down native forests for fuel. The cultivation will help provide shade, conserve soil, store CO2 and regulate water flows, helping small-scale farmers adapt to more frequent droughts and floods by diversifying from their traditional mainstays of cotton, beans, cassava, sesame and sugarcane.
