Water scarcity and agricultureWater scarcity and agriculture
A comprenhensive assessment of Water Management in agriculture:Question: Is there enough land, water, and human capacity to produce food for a growing population over the next 50 years—or will we “run out” of water?The Comprehensive Assessment’s answer: It is possible to produce the food—but it is probable that today’s food production and environmental trends, if continued, will lead to crises in many parts of the world. Only if we act to improve water use in agriculture will we meet the acute freshwater challenges facing humankind over the coming 50 years.
Water scarcity and agricultureWater scarcity and agriculture
A comprenhensive assessment of Water Management in agriculture:Question: Which efforts are necessary to provide fresh water ?The Comprehensive Assessment’s answer: The efforts depend on the technology used:1.Seawater desalination: energy demand 7 – 12 kWh/m³, generation of brines with high salt concentration (waste disposal problem!), usually large centralised units,2.Decentralised MBR technology: energy demand <1 … 3 kWh/m³, generation of surplus sludge with high organic matter and nutrient content (fertiliser + soil conditioner!), tailor made systems.

The NaWaTech concept
• Natural water systems and treatment technologies to cope with water shortages in urbanized areas in India. • Projects respond to the call ENV.2012.6.6-1: EU -India
cooperation in water technology and management and to the corresponding call of the Department of Science & Technology in India. The planned activities support the objectives of the Strategic Forum for International Science and Technology Cooperation (SFIC). • Aims at maximizing the explotation of natural and compact
technical systems and processes for the effective management of municipal water resources of water supply and sanitation services, and of the municipal water cycle as a whole in urbanized areas of India.
The NaWaTech concept
• The NaWaTech concept is based on the optimised use of different urban water flows by means of a multi-barrier approach. Taking into account the different nature and degree of pollution, each water flow is managed, treated and reused individually, supplementing traditional water sources to cope with shortages in Indian urban settlements.
The NaWaTech concept
Blackwater and greywater (as separated streams or mixed) can be treated through the combination of an anaerobic process (producing energy and biogas) plus Constructed Wetlands (CW) or treated through aerobic technical water treatment systems (SBR or MBR). In both cases the effluent can be either discharged to the surface waters or reused in urban agriculture or landscaping. Stormwater can be collected and pre-treated in CW before it is filtered through the soil and stored in the aquifer. Rainwater can be collected on rooftops and parking lots and used in the households or fed into the aquifer.
In addition, a cost-effective and viable post-treatment option can be developed based on different steps depending on the use to be given to the stream, and therefore water quality requirements. The different systems will be integrated into the urban scene providing additional socio-economic functions, including flood management, buffering of seasonal availability of water and recreational space for the urban dwellers. This holistic approach will minimize the urban water footprint and enhance the water security of the area, as the water cycle is closed at a local level. It also minimizes the pollution of water sources for downstream users.
NaWaTech Objetives
The specific objectives of NaWaTech are: To assess the technical, financial and environmental potential of
natural water treatment technologies to cope with water shortages in urbanised areas in India.
To enhance the natural water treatment systems for the production of recycled water to supplement water sources considering extreme climatic conditions and highly varying pollutions loads.
To disseminate, exploit, and ensure the take-up in practice and mainstreaming of NaWaTech activities and outputs by key stakeholders.
To benefit Indian and European SMEs in the water sector, by supporting the development of a local market forinnovative water treatment technologies, and training the SMEs on the NaWaTech approach.
To create an enabling environment in order to allow the take-up in practice and mainstreaming of the results.
To establish foundations of a long-term cooperation between EU and India in water technologies.
