India’s civil society has opposed engineering-based water management such as large dams, river linking and canal irrigation, for environmental and social reasons, but often ideological reasons.
India's civil society, which for the past 30 years has been critical of India's water policies, now has the opportunity to drive the policy recommendations for water management.

When women have to spend hours getting water for their families, it comes at the expense of their incomes and their other contributions to their communities.
Knee-jerk responses to water insecurity won't fix the basin. The harder and longer path is delivering real water reform, including transparent water planning enshrined in law.

Instead of allocating the Nile waters based on a fixed, perpetual water supply Ethiopia, Sudan, and Egypt must consider changes in weather patterns, among other factors.

Green iguanas are an invasive species that seem to be spreading and proliferating in Florida. Used to warmer temps, they switch into torpor mode when the mercury drops.
Access to the shoreline is great, but what about places not on the coast?

Research into public health benefits of integrating nature into cities has focused on green spaces. New studies suggest water features are just as useful and can piggyback on other infrastructure goals.
The Adelaide Desalination Plant will be cranked up to full capacity to free up 100 gigalitres of water from the River Murray for use by farmers.
The Australian government is effectively spending A$95 million so it can sell water to farmers for A$10 million.
The push to ‘drought-proof’ Australia is dangerous nonsense.

Yes, Australia naturally cycles through dry and wet periods. But that doesn't mean we can simply build more dams and trust they'll be filled.
Let’s say we took a lot of water from the coast and piped it to a dry inland area. How might that affect the soil in both places?
The Australian landscape is very old and the soils in inland areas can be very fragile.
After years of delay, the New Zealand government is pushing ahead on a national plan to clean up the nation’s lakes, rivers and wetlands.
A proposed plan to clean up New Zealand's waterways draws clear limits on the expansion of dairy farming and irrigation, as well as on the use of nitrogen fertiliser in some key areas.
The receding waters of Lake Pamamaroo, in western NSW, in February 2019. Reduced water supply, due to lower rainfall and higher temperatures, has been the main cause of increasing water prices.
High water prices in the Murray-Darling Basin are blamed on foreign investors and corporate speculators. The simple truth is they are caused mostly by lack of rain.
The white “bathtub ring” around Arizona’s Lake Mead (shown on May 31, 2018), which indicates falling water levels, is about 140 feet high.

Western states adopted a 7-year plan in May 2019 to manage low water levels in the Colorado River. Now they need to look farther ahead and accept that there will be less water far into the future.
Millions of women in Africa spend long hours collecting water.
Any policies and interventions around water management can only really be successful if women are included.
Chemicals poured down the sink or pumped into the atmosphere can eventually end up in the groundwater, which means less available fresh water for us to use.
While making small volumes of pure water in a lab is possible, it’s not practical. The reaction is expensive, releases lots of energy, and can cause really massive explosions.
A woman draws water from a hand pumped well in northern Ghana.
Many African countries tend to mismanage their groundwater resources.
Reliable water supply is essential for South Africa’s development.
South Africa is a water stressed country but crisis point can be avoided.
When a stream enters a culvert, the flow can be concentrated so much that water flows incredibly fast. So fast, in fact, that small and juvenile fish are unable to swim against the flow and are prevented from reaching where they need to go to eat, reproduce or find safety.
Our new invention tackles one of the greatest impediments to fish migration in Australia: culverts, those tunnels or drains often found under roads.
Heavy rainfall recently devastated large swathes of Kerala, India.
Green infrastructure can be a valuable tool in helping vulnerable communities to face the double threat of flooding and drought.
Africa’s waterways, like the Barotse floodplain in Zambia, must be properly managed.
African countries need to urgently develop coherent and strategic policies around water, land and agriculture.
Cape Town narrowly avoided “Day Zero,” but that doesn’t mean the city is resilient to future water shortages.
Cape Town faced down "Day Zero" earlier this year, but that doesn't mean its water system is resilient. Other cities should also take note.
