Descripción
Climate change is projected to change production conditions for agricultural producers globally. In the developing world, most of the projected changes will result in a reduction of agricultural productivity, with concomitant reductions in food security. Because agricultural production remains the main source of income for most rural communities, adaptation of the agricultural sector to the adverse effects of climate change will be imperative to protect and improve the livelihoods of the poor a nd to ensure food security. Adaptation will require farmers to make adjustments and employ a range of actions to enhance the resilience of local food systems that increase their net revenue by reducing the potential damage from climate change. Their capacity to make the required adjustments depends on the existence of policies and investments to support farmers’ access to materials and information, as well as to provide the proper economic incentives to stimulate changes. Responding to a changin g climate will also require changes in PGRFA management to address both immediate and slow onset changes. There are a range of adaptation options involving changes in PGRFA management, including changing crops, varieties and farming practices. These options are not mutually exclusive, and in fact are most often used on combinations (e.g. changing farming practices also involves changes in crops and varieties). Based on a wide range of literature review and our own empirical analysis, this paper argue that an enabling condition for PGRFA management for adaptation is the broadening of the genetic resource base farmers can access to enable them to change crops, varieties and farming systems to meet changing climate conditions.
