| Abstract | Agriculture is and will be affected negatively by climate change in many regions. Most vulnerable are poor agricultural communities in the Global South and assuring food security for the twenty-first century requires successful adaptation to climate change in agriculture. Besides being affected by climate change, agriculture also contributes significantly to it. Some 10–15 per cent of total global greenhouse gas emissions are direct agricultural emissions. Adding emissions from conversion to agricultural land increases this share to more than 30 per cent. This chapter addresses the potential of organic farming systems to adapt to climate change. Depending on the context, the focus lies on the adaptation of the agricultural production system, of a community or at farm level. Adaptation strategies can be as diverse as changes in varieties cultivated (e.g. with increased drought resistance) or in management practices (e.g. mulching instead of burning of crop residues to reduce irrigation needs), physical investments for improved water management, a change in livelihoods from crop farming to animal husbandry, or even migration. Assessing success of adaptation can take several years to decades and some initially successful adaptation strategies may turn out to be a failure later on. Furthermore, the concepts used to frame adaptation in agriculture, such as resilience, need some further clarification and discussion. In this chapter, first we review briefly the main impacts of climate change on agriculture. We then present and clarify the key concepts for discussing adaptation measures in agriculture and address key challenges for their implementation. Subsequently, we analyse the adaptation potential of organic agriculture. We find that organic agriculture addresses most of the important challenges of successful adaptation. We also find that the current adaptation discussion in general does not sufficiently include the full adaptation potential of soil fertility (namely high levels of soil organic matter), of crop ... |
