The Food and Agricultural Organization (FAO) defines Climate Smart Agriculture (CSA) as an approach that helps to guide actions needed to transform and reorient agricultural systems to effectively support development and ensure food security in a changing climate. Further, according to FAO, such an approach aims to tackle three main objectives: sustainably achieving agricultural productivity and incomes; adapting and building resilience to climate change; and reducing and/or removing Greenhouse Gas (GHG) emissions, where possible. Critical to achieving these objectives is a major shift in the way land, water, soil nutrients and genetic resources are managed with related shifts in local/national governance, legislation, policies, financial mechanisms and improving the farmers’ access to markets.
CSA, further, takes into consideration the diversity of social, economic and environmental contexts including agro-ecological zones/farming systems where it is to be applied. Implementation herein requires identification of integrated package of climate resilient technologies and practices for management of water, energy, land, crops, livestock, aquaculture etc at the farm level while considering the linkage between agricultural production and ecosystems services at the landscape level. Testing and applying different practices, experts opine, is important to expand the evidence base, determine which practices and extension methods are suitable in each context. This leads to identification of synergies and tradeoffs between food security, adaptation and mitigation.
CSA, thus, provides the broad enabling framework to help stakeholders, whether national or international, to identify sustainable agricultural strategies suitable to their local conditions. In this context, FAO actions in CSA e.g. policy structures, practices, investment and tools are a valuable repository for policymakers and administrators to learn about such agricultural strategies. This includes the critical baseline strategy to assess the past and future impact of climate variability on agriculture and consequent vulnerability of farming communities, especially, smallholder farmers. Needless to state that agriculture has the potential to mitigate between 5.5-6 gigatonnes of carbon dioxide (equivalent) annually (IPCC, 2007) with most of this potential in developing countries. Hence, to realize this potential, agricultural development efforts will have to support smallholder farmers for the uptake of climate smart practices at the farm and landscape levels and along the value chain, too.
