Helsinki Rules
1966 - “Equitable share” of drainage basin
Berlin Rules
2004 - “equitable share” as well as environmental protection and human rights to water
Zero tillage
No ploughing - reduces carbon lost via oxidation, reduces run off & overland flow by compacted soils
Mulching
Leaving old matter in soil - increased soil fertility = higher growth and yield - more organic matter in soil = more porous = better infiltration capacity = less flooding
Domestic ways to reduce water
More efficient appliances (eco settings on washers)
Limiting daily usage (turning tap off whilst brushing teeth)
Ways to conserve water in industry
Reusing recycled wastewater
Ways to conserve water in agriculture
Drip irrigation
Reusing recycled waste water
Rainwater collecters
