Q

What is water allocation

A

In countries with scarce amounts of water, governments have to allocate water resources
Agriculture uses 70% of water withdrawals and 90% of consumption
Minimising water losses to evaporation- mulching, drip irrigation
Recovering and recycling of waste water from agriculture

Q

What is drainage basin planning

A

Targeting Run-off, surface water storage and groundwater
Surface water storage is improved by conserving wetland and temporary storage on floodplains
Groundwater levels are maintained by limiting abstraction
Artificial recharge - injecting into aquifers through boreholes
