Is natural gas in good shape for the future?
Natural gas demand rebounded and grew by an estimated 3% in 2017. China alone accounted for nearly 30% of global growth – with more than 30 bcm out of a total of nearly 120 bcm. In the New Policies Scenario to 2040, global natural gas consumption expands at an average rate of 1.6% per year to 2040, lower than the estimated 3% achieved in 2017 but a much higher rate than oil (0.5% per year on average) and coal (essentially flat). More than 80% of this growth takes place in developing countries, led by China, India and other countries in Asia. The challenge for the gas industry is that much of the gas needs to be imported (and so transportation costs are significant); infrastructure is often not yet in place; and policy-makers and consumers are very sensitive to questions of affordability.

Recycled water can satisfy most water demands, as long as it is adequately treated to ensure water quality appropriate for the use.
Recycled water is most commonly used for non potable purposes, such as agriculture, landscape, public parks, and golf course irrigation. Other non potable applications include cooling water for power plants and oil refineries, industrial process water for such facilities as paper mills and carpet dyers, toilet flushing, dust control, construction activities, concrete mixing, and artificial lakes. A number of projects use recycled water indirectly for potable purposes. These projects include recharging ground water aquifers and augmenting surface water reservoirs with recycled water. In ground water recharge projects, recycled water can be spread or injected into ground water aquifers to augment ground water supplies, and to prevent salt water intrusion in coastal areas. The use of gray water at decentralized sites for landscape irrigation and toilet flushing reduces the amount of potable water distributed to these sites, the amount of fertilizer needed, and the amount of wastewater generated, transported, and treated at wastewater treatment facilities.

According to a plan released by the State Council on October 20th, China plans to take more measures to develop modern agriculture in the next five years.
The objective is to build an efficient, environment-friendly and resource-saving agriculture, maintain the supply of agricultural products and improve farmers’ income.
The national output of grain in 2020 is expected to reach 550 million tonnes, 50 million tonnes more than in 2015. China’s productivity is expected to increase to more than 47,000 yuan, compared with just 30,000 yuan in 2015.
The plan also called for the expansion of external cooperation of agriculture industry, with efforts to optimize cooperation layout and promote the healthy development of the trade of agricultural products.

Saudi Arabia has approved financial support for the environment, water and agriculture sectors worth 92 billion riyals ($24.5 billion).
Abdulrahman al-Fadhli, minister for environment, water and agriculture, said in a conference that his ministry had received “support” from the government to achieve 16 strategic goals which are in line with the economic transformation program Vision 2030: this program aims to diversify the economy by reducing dependence on oil revenues.

Overall, industry (including energy) uses about 19% of the world’s total water withdrawal.
According to the IEA, energy uses about 15% of the total, which implies approximately 4% for large industry and manufacturing. It is predicted that by 2050 manufacturing alone will increase its use by 400%. Industry’s water-dependence ranges from the large users in food and beverage and the mining industry to SMEs. Water use is further expanded if the total water footprint of an industry or individual facility is considered.
As industrial technology and understanding of the essential role of water in the economy and of the environmental stresses placed upon the resource improve, industry is taking measures to reduce its water use per unit produced, thereby improving industrial water productivity. Increased attention is being directed to water quality, particularly downstream. Industry is also putting efforts to reuse and recycle water, matching water quality to use and moving towards cleaner production, with possible benefits in terms of better paid jobs within industry as well as treatment equipment suppliers.

To provide supplemental water and wastewater service, the San Francisco Public Utilities Commission (SFPUC), in the USA, is embracing decentralized water treatment systems.
SFPUC launched a local programme for regulating on-site water use called the Nonpotable Water Program, which creates a streamlined process for new developments to collect, treat and reuse alternative water sources, including grey water and blackwater, from large-scale commercial and residential buildings in order to meet their non-potable needs. It establishes guidelines for developers interested in installing non-potable water systems in buildings. Subsequently, the SFPUC realigned governmental policies and created a new regulatory framework by collaborating with the San Francisco departments in charge of Building Inspection and Public Health. SFPUC allowed for micro-markets to emerge when two or more buildings share, buy or sell water without a public agency providing the service. The programme shifts the burden of operation, maintenance and water quality compliance to the private sector while the public sector maintains oversight to ensure the protection of public health and the public water system.
