By John Parnell<\/a><\/strong><\/p>\n

Energy, water and land are being squandered as the world throws out as much as half the food it produces.<\/strong><\/p>\n

A report,\u00a0Global Food: Waste Not Want Not<\/a>, by the UK\u2019s Institute of Mechanical Engineers (IMechE) has found that 30-50%, or 1.2-2 billion tonnes, of produced food is wasted by poor storage, bad distribution and exacting quality standards in the developed world.<\/p>\n

\u201cAs water, land and energy resources come under increasing pressure from competing human demands, engineers have a crucial role to play in preventing food loss and waste by developing more efficient ways of growing, transporting and storing foods,\u201d said Dr Tim Fox, head of energy and environment at the Institution of Mechanical Engineers.<\/p>\n

\u201cBut in order for this to happen Governments, development agencies and organisation like the UN must work together to help change people\u2019s mindsets on waste and discourage wasteful practices by farmers, food producers, supermarkets and consumers.\u201d<\/p>\n

With the global population set to top 9 billion with scarce water and energy resources and climate change making conditions for farmers even harder, cutting waste could help to reduce surging food prices<\/a>.<\/p>\n

“Most people don’t realise that food waste is not only a moral\u00a0conundrum\u00a0 wasting food when so many people are hungry, but an environmental problem as well,” Danielle Nierenberg, co-founder of the Food Tank<\/a> told RTCC.<\/p>\n

“We forget that all of the resources and ingredients, that go into making food,artificial fertilizer and other agrochemicals, water, soil fertility, fossil fuel energy, etc, are also wasted when we either food is lost because of pests, disease, or improper storage or because we simply throw it away.”<\/p>\n

Agriculture uses 2.7 trillion cubic metres of water a year, that\u2019s 70% of all freshwater use. Wasting 2 billion tonnes of food also means wasting 35% of the world\u2019s fresh water supplies.<\/p>\n

The World Economic Forum\u2019s Global Risk report identified water scarcity<\/a> as the top societal threat facing the world.<\/p>\n

Water is also under increasing demand from the growing populations, industrialising nations and to\u00a0fulfill\u00a0an expanding appetite for hydropower<\/a>.<\/p>\n

Hydropower rich Brazil is currently facing a water and energy crisis following a dry summer. India recently announced plans to build 292 dams<\/a> in the Himalaya to solve its energy crisis but there are concerns the resulting effect on water supplies could be worse.<\/p>\n

While improved farming techniques have improved crop yields, land degradation<\/a> from poor management and aggravated by climate change means 12 million hectares of land become barren each year.<\/p>\n

The IMechE report,\u00a0notes that just one hectare can provide enough rice or potato for 22 people a year.<\/p>\n

“At a time when 870 million go to bed hungry each night, and climate change is already acting as a break on crop yields and pushing up food prices, our waste of food cannot continue,” Tim Gore, Oxfams’s international policy advisor on climate change.<\/p>\n

“With demand for food set to increase in the years ahead, we must change our wasteful behaviour in rich countries, boost investment in small scale farming in poor countries, and slash the greenhouse gas emissions that are increasing the costs of feeding a warming world,” he told RTCC.<\/p>\n

As nations develop, the appetite for meat<\/a> also increase placing additional pressures on the amount of land required to feed the population.<\/p>\n

According to the IMechE report, producing 1 calorie of food requires 7-10 calories of energy input. As agriculture becomes increasingly mechanised this figure could rise.<\/p>\n

Meeting fuel and electricity demands for agricultural production, storage and transport with sustainable sources is essential, IMechE claims.<\/p>\n","protected":false},"excerpt":{"rendered":"New
