“Water can help fight climate change. There are sustainable, affordable and scalable water and sanitation solutions.” is the key campaign message of #WorldWaterDay2020. Here’s how in detail !
Improving carbon storage: Peatlands cover about 3% of the world’s land surface but store at least twice as much carbon as all of Earth’s forests. Mangrove soils can sequester up to three or four times more carbon than terrestrial soils. Protecting and expanding these types of environments can have a major impact on climate change.
Protecting natural buffers: Coastal mangroves and wetlands are effective and inexpensive natural barriers to flooding, extreme weather events and erosion.
Harvesting rainwater: Rainwater capture is particularly useful in regions with uneven rainfall distribution to build resilience to shocks and ensure supplies for dry periods.
Adopting climate-smart agriculture: Practicing conservation agriculture to improve soil organic matter (needed for the soil to retain water), reducing post-harvest losses and food waste, and transforming waste into a source of nutrients or biofuels/biogas can address both food security and climate change.
Reusing waste water: Unconventional water resources, such as regulated treated wastewater, can be used for irrigation and industrial and municipal purposes.
