Agriculture and Climate Change Mitigation
Agriculture is a major contributor to climate change, representing 20 to 25 percent of annual global greenhouse gas emissions. Agriculture also offers major opportunities to combat (i.e. mitigate) climate change in two distinct ways:
- reducing greenhouse gas emissions from farms via CSA technologies such as conservation tillage and precision fertiliser use, and
- sequestering carbon dioxide, or converting it into physical form and hence removing it from the atmosphere. Carbon dioxide can be sequestered into carbon sinks such as soil or wood via CSA technologies such as agroforestry and composting. Carbon sinks account for 90 percent of agriculture’s mitigation potential, which is concentrated in developing countries.
Advocates of CSA emphasise the potential of CSA technologies to meet these two objectives simultaneously and of mitigation initiatives to be pro-poor, ie., beneficial to small-scale farmers in developing countries, many of whom are poor. Notably, these farmers can benefit from mitigation initiatives via both cash payments for delivering ecosystem services and the inherent benefits of appropriately targeted CSA technologies. CSA advocates often focus their efforts on finding ways to harness this potential, whether under carbon trading schemes or public sector mitigation initiatives (i.e., NAMAs).
However, critics question whether efforts to mitigate climate change via farming can really benefit poor farming communities, noting for instance that high transactions costs make it hard for such farmers to participate in carbon projects. They also highlight the potential for mitigation initiatives to benefit powerful actors such as agribusiness, government and consultants while adversely affecting communities, for example by limiting their control over land.
