Climate change

Energy-related carbon dioxide emissions along the agrifood chain are produced from the combustion of fossil fuels to run machinery, generate heat and electricity for food storage and processing, and from the use of petroleum fuels for food transport and distribution. Energy is essential for food security and development, but current food production and energy use patterns are unsustainable if climate change targets are to be met.

• Primary food production and the food supply chain, including landfill gas produced from food wastes, contribute approximately 22 percent of total annual greenhouse gas emissions.
• An additional 15 percent of greenhouse emissions results from land use changes, particularly changes linked to deforestation brought about by the expansion of agricultural land.

FAO along with other partners is promoting climate-smart agriculture, forestry and fisheries that can sustainably increases productivity; adapt to climate change; build resilience to shocks and variability; reduce and remove greenhouse gases; and enhance the achievement of national food security and development goals. The ESF Programme is an essential component of climate-smart agriculture as it assesses the energy implications of climate-smart interventions.

Energy-smart practices are also climate-smart

A number of climate-smart agriculture practices, particularly those related to sustainable intensification production, can lead to a reduction in the use of external fossil-fuel derived inputs. Integrated Pest Management (IPM), an ecological approach to manage pests through the use of biodiversity and biological processes, not only improves crop production, builds resilience, but also reduces the need for fossil fuel-based pesticides.  Likewise the application of low-carbon energy technologies contributes to climate-smart agriculture objectives. For example, the use of solar concentrators or ovens by cooperatives or small farmers associations can create new opportunities for food processing in rural areas and extend the shelf life of perishable products to avoid food losses. Becoming energy efficient increases climate resilience, reduces energy consumption and lowers greenhouse gas emissions.

Bioenergy and Climate Change

The first of the GBEP sustainability indicators, developed with the contribution of FAO, provides guidance to measure the lifecycle greenhouse gas emissions from bioenergy production and use, as per the methodology chosen nationally or at community level, and to report these emissions using the GBEP Common Methodological Framework for GHG Lifecycle Analysis of Bioenergy V1, a flexible tool for communicating and comparing methodologies used in GHG LCA of bioenergy systems.

The BEFS Analytical Framework and the associated tools address the greenhouse gas emission reduction potential of different biofuel production pathways.
