Types of adaptation • Reactive and anticipatory adaptation • Reactive • institutions, individuals, plants and animals make in response to climate change, after the fact. • Anticipatory • deliberate decisions to prepare for potential effects of climate change; i.e. taken in advance of climate change, before the fact. • requires foresight and planning, whereas reaction does not require but may involve foresight and planning. • Autonomous and planned adaptation • Autonomous adaptation • natural or spontaneous adjustments in the face of a changing climate • Planned adaptation • conscious intervention, e.g. building sea walls. • may be used to influence (autonomous) adaptation by other actors Training on Ecomomic Analyses of Climate Change
Strategies to reduce sensitivity or increase coping capacity Training on Ecomomic Analyses of Climate Change
Examples of Agricultural Adaptation • Crop diversification • Introduction of new crops • Extensification of most hardy crops • Development of irrigated agriculture/Improved irrigation efficiency • Shifting planting dates • Reduction of post-harvest losses • Soil fertilisation • Irrigation • Training programmes and dissemination • Research and development of new (salinity and drought resistant) crops Training on Ecomomic Analyses of Climate Change
Adaptation strategies can be categorized into four major categories • Agricultural techniquesto adapt to changes in rainfall regime, which include e.g. seed selection, adapt planting dates, adapt fertilizer application, adapt feed techniques, improve food storage facilities, change of pastoral system; • Water management techniquesto adapt to changes in rainfall regime, which include e.g. use of water harvesting techniques, rehabilitate terraces, improve irrigation techniques, improve watering sites in pastoral areas; • Diversification techniquesin order to diversify the income sources, which include e.g. temporal or permanent migration, use of alternative sources for fuel wood, home-garden agriculture, changes in the consumption pattern or reductions of livestock herds; and • Communal pooling techniques, which include e.g. reforestation, rangeland preservation, communal food storage facilities or local water management rules.
