In pictures: Adapting to climate change

image captionIn 2013, New York mayor Michael Bloomberg unveiled plans to protect the Big Apple from the future effects of climate change, such as storm surges and sea level rise. This conceptual image shows wetlands and a tidal barrier to shield Coney Island and Gravesend.
image captionThe IPCC report says many global risks of climate change are concentrated in urban areas. New York is studying the construction of a multi-purpose levee along the eastern edge of Lower Manhattan that would protect against storm surges and sea-level rise.
image captionThe plans were announced a year after New York was seriously affected by Hurricane Sandy. The city was subjected to widespread flooding and large areas lost electricity. The economic losses were estimated at $18bn.
image captionElsewhere in the world, other methods to protect against flooding from the sea are being used. Here, an Indian man nurtures mangrove seedlings. The planting of mangroves can act as a natural defence as sea levels rise.
image captionAgriculture might respond to climate change through the use of new crop varieties better suited to new conditions. Here, a farmer prepares to plant a variety of drought-tolerant maize derived through conventional breeding.
image captionThe Southern Besor reservoir in Israel contains a mixture of recycled, purified waste-water and stored rainwater for agricultural use. The waste water that now flows here was once allowed to flush out to sea. Increasing water storage is a major issue in climate change adaptation.
image captionDesalination plants convert salty ocean water into drinking water for needy populations, or in the case of this example in Beckton, UK, a mixture of sea water and river water from the tidal Thames. But desalination is controversial as a solution to water scarcity because, in general, it can be energy-intensive and expensive.
