Our planet’s water sources are under constant threat from global warming, overuse and abuse, microplastics and other pollutants, to name just a few of the ongoing challenges. Circular water strategies are an inspiring response to these threats.
Each year since 1991 the Stockholm International Water Institute (SIWI) has awarded the prestigious Stockholm Water Prize on March 22, World Water Day. This year the focus is on groundwater management.
Urban agriculture is growing, albeit for different reasons in different sectors. In developing countries or in low-income areas of developed countries, people are highly motivated to grow their own food in order to lower their food costs.
With the present population, the water volume per capita is about 4,000 m3 per year, which is exactly the threshold between water security and water shortage as determined by the International Water Resources Association.
Cutting-edge technologies – from IoT connectivity to big data predictive analytics – are revolutionizing the agriculture market. Critical data about soil, water, weather, etc. is collected and transmitted by agricultural drones or sensors connected to gateways and IoT platforms.
When it comes to water shortages, it is the responsibility of water authorities to both encourage conservation as well as seek out new, sometimes non-traditional sources of potable water. One of the more cost-effective means of increasing water supplies is wastewater recovery and reuse.
