Advertisement Recently, the World Economic Forum listed water scarcity as one of the three global systemic risks of highest concern, an assessment based on a broad global survey on risk perception among representatives from business, academia, civil society, governments and international organizations1.
Freshwater scarcity manifests itself in the form of declining groundwater tables, reduced river flows, shrinking lakes and heavily polluted waters, but also in the increasing costs of supply and treatment, intermittent supplies and conflicts over water.
Future water scarcity will grow as a result of various drivers: Water-use efficiency improvements may slow down the growth in water demand but, particularly in irrigated agriculture, such improvements will most likely be offset water business plan in india increased production.
Similarly, water storage and transfer infrastructure improve availability, but allow further growth in demand as well. Climate change will probably increase the magnitude and frequency of droughts and floods. The expected increase in climate variability will compound the problem of water scarcity in dry seasons by reducing water availability and increasing demand, the latter owing to higher temperatures and the need to make up for lost precipitation3.
The private sector is becoming aware of the problem of freshwater scarcity Water risk Water shortage and pollution pose a physical risk to companies, affecting operations and supply chains4. They also face the risk of stricter regulations; what form these will take — for example, higher water prices, reduced rations, stricter emission permits or obligatory water-saving technology — remains unclear.
Furthermore, brands face a reputational risk because the public and media are becoming increasingly aware that many companies contribute to unsustainable water use5.
Even companies operating in water-abundant regions can be vulnerable to water scarcity, because the supply chains of most companies stretch across the globe.
Countries such as the USA, Brazil, Argentina, Australia, India and China are big virtual water exporters, which means that they intensively use domestic water resources for producing export commodities above.
In contrast, countries in Europe, North Africa and the Middle East as well as Mexico and Japan are dominated by virtual water import, which means that they rely on import goods produced with water resources elsewhere.
The water use behind those imported goods is often not sustainable, because many of the export regions overexploit their resources. Many companies — particularly multinationals — have started to assess their water risk and in the near future we may expect to see an increasing number of them developing response strategies.
At best, however, this will only partially mitigate the problem of water scarcity. A critical perspective is that corporate engagement on water is a cynical attempt by businesses to extend control over the resource or just an effort to maintain a favourable brand image7.
A more optimistic perspective is that an increasing number of companies are genuinely concerned about growing water scarcity and looking for mitigating strategies, but even then it is unlikely that economies will structurally change without governmental regulation.
The reason for this is that water is a public good, vulnerable to free-rider behaviour, and water scarcity and pollution remain unpriced. Water use is subsidized in many countries, either through direct governmental investments in water supply infrastructure or indirectly by agricultural subsidies, promotion of crops for bioenergy or fossil-energy subsidies to pump water.
Water stewardship Managing water risk is generally confused with good water stewardship.
The former can contribute to the latter, but water stewardship entails more than managing water risk. Water stewardship includes the evaluation of the sustainability of water use across the entire value chain, the formulation of water consumption and pollution reduction targets for both the company's operations and supply chain, the implementation of a plan to achieve these targets and proper reporting on all of this.
In priority catchments, it requires the pursuit of collective action and community engagement8,9, For most companies, moving towards a sustainable supply chain is a much bigger challenge than greening their own operations, because the water footprint of the supply chain is often up to a hundred times bigger than the company's operational footprint and can be influenced only indirectly.
Common reduction targets in the beverage industry, such as going from 2 to 1. Companies should strive towards zero water footprint in industrial operations, which can be achieved through nullifying evaporation losses, full water recycling and recapturing chemicals and heat from used water flows.Water resources are natural resources of water that are potentially useful.
Uses of water include agricultural, industrial, household, recreational and environmental activities. All living things require water to grow and reproduce. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.
A new plan to speed up the way the US government does business related to federal waters may leave some cities footing a bigger bill for clean drinking water. Key Points. India faces national water scarcity by if current trends continue.
States that usually have surplus water, such as Latur and Uttarakhan, currently experience acute water scarcity. China and India often are compared in the same breath by western executives weighing sites for expansion or outsourcing, but the reality of the situation is that in terms of infrastructure, China is decades ahead of India – an important consideration for industries reliant on strong power, water, transport or information infrastructure.
The Water (Prevention and Control of Pollution) Act was enacted in to provide for the prevention and control of water pollution, and for the maintaining or restoring of wholesomeness of water .
