Adaptation to water-related risks and impacts make up the majority of all documented adaptation . For inland flooding, combinations of non-structural measures like early warning systems and structural measures like levees have reduced loss of lives . Enhancing natural water retention such as by restoring wetlands and rivers, land use planning such as no build zones or upstream forest management, can further reduce flood risk . On-farm water management, water storage, soil moisture conservation and irrigation are some of the most common adaptation responses and provide economic, institutional or ecological benefits and reduce vulnerability . Irrigation is effective in reducing drought risk and climate impacts in many regions and has several livelihood benefits, but needs appropriate management to avoid potential adverse outcomes, which can include accelerated depletion of groundwater and other water sources and increased soil salinization . Large scale irrigation can also alter local to regional temperature and precipitation patterns , including both alleviating and exacerbating temperature extremes . The effectiveness of most water-related adaptation options to reduce projected risks declines with increasing warming .
