![]() Integrated management of water-food-energy must be a top priority. ‘Green infrastructure’, such as land dams to capture runoff in arable fields or planting forests to protect soil and assist groundwater recharge, are some examples of creating a more sustainable water-food-energy nexus and a ‘greener’ economy. Governments must harness the power of nature instead of allowing its destruction and degradation in the pursuit of food and energy. Efficiency measures along the entire agrifood chain can help save water and energy, such as precision irrigation based on information supplied by water providers, and protection of ecosystems alongside agriculture and energy production can ensure environmental integrity.Įcosystems must be valued for their vital services. The integrated systems of land, soil and water are being stretched to breaking point. Geothermal energy has great potential as a long-term, climate independent resource that produces little or no greenhouse gases and does not consume water. There needs to be much more support for the development of less water-intensive renewable energy, such as hydropower and wind. Governments must increase renewable energy sources. ![]() ![]() UN Photo/Anne Lydia Sekandi The way forward As water becomes more scarce and stretched, its ability to support progress in several of the SDGs, particularly on poverty, hunger, sustainability and the environment, is being reduced. Pressure on the water-food-energy nexus threatens the Sustainable Development Goals (SDGs). The vast majority of energy generation is water intensive, such as its use in coal-fired power plants and in nuclear reactors, and in bio-fuel crop production. Agriculture is the largest consumer of the world’s freshwater resources, and more than one-quarter of the energy used globally is expended on food production and supply. There is a significant global move away from a mainly starch-based diet to an increasing demand for more water-intensive meat and dairy as incomes grow in many countries.įood production and energy are highly water intensive. Pressure on the nexus is being driven by a rising global population, rapid urbanization, changing diets and economic growth. PUB has been rallying the local community and businesses to support the water cause in their own ways throughout March, with their #GoBlue4SG movement.UN Photo/ Patricia Esteve The issue explainedĭemand for water, food and energy is increasing. ![]() Tertiary institutions will also take part for the first time, comprising Singapore Management University, Singapore Institute of Technology, ITE College, Nanyang Academy of Fine Arts and Temasek Polytechnic. Sixteen new buildings – including Capitol Singapore, The Fullerton Hotel, Marina Bay Financial Centre and SkyHelix in Sentosa – will join the initiative along with returning partners such as ION Orchard and the ArtScience Museum. PUB’s “City Turns Blue” initiative will see a record 56 prominent landmarks and buildings "illuminated in dazzling blue", including the Singapore Pavilion Expo 2020 Dubai on the global stage, the agency said in a news release on Thursday (Mar 17). ![]() SINGAPORE: Singapore’s skyline will turn into a sea of blue from Mar 19 to 22 to commemorate World Water Day, signalling the country’s “steadfast commitment to water sustainability”. ![]()
