Management strategies - water cycle
Forestry
Crucial nature of forests recognised by UN and World Bank - REDD and FCPF (Forest Carbon Partnership Facility)
Financial incentives to protect + restore forests are a combination of carbon offsets and direct funding
The ARPA programme (Amazon Regional Protected Areas) expands to about 128 million acres of the Amazon Basin (aiming to be 150 million).
There was a 75% decrease in deforestation rates subsequently
Benefits
Stabilising regional water cycle, offsetting 1.4 billion tonnes of carbon a year
Supporting indigenous forest communities
Promoting eco-tourism
Protecting genetic bank
Water allocations
Agriculture is the biggest user of water as globally it accounts for 70% of water withdrawals and 90% of consumption
Wastage of water occurs through evaporation and seepage through inefficient water management like over-irrigating crops
Improved management techniques which minimise evaporation like mulching, zero soil disturbance and drip irrigation
Losses by run-off can be reduced through terracing, contour ploughing and vegetative strips
This method isn't used much outside of the developed world
Drainage basin planning
Most effective at a drainage basin scale
Targets for drainage basin planning = run-off, surface water and groundwater storage
Rapid run-off is controlled by reforestation programmes, reducing artificial drainage and extending permeable surfaces in urban areas.
Surface water storage improved through conserving and restoring wetlands as well as floodplain use
Groundwater levels conserved by limiting abstraction and by artificial recharge, where water is injected into aquifers via boreholes
