If food waste were a country, it would be the third largest source of GHG emissions on the planet, of which 61% comes from households. Meanwhile, according to FAO, more than 800 million people are undernourished while 2 billion are micronutrient deficient.

In the lead up to the International Day of Awareness of Food Loss and Waste on 29 September, check out these 12 apps that help prevent household food waste and protect the planet.

How will we feed a growing population? Some say we must grow more food. But another part of the answer is that we must reduce how much food is lost or wasted from farm to fork. Today, 40% of food grown never gets eaten—1 billion more tonnes (1.1 billion tons) of food than previously estimated, according to a new report, Driven to Waste, by WWF and UK-based partner Tesco.

Establishing a sustainable food supply in the middle of the desert is extremely challenging. High temperatures throughout the year making it inhospitable for farming and lack of fresh water for irrigation are just two among many other challenges.

How to create a smart and sustainable food supply in the desert, taking the case of Red Sea Project as an example?

“People can feed their own families, even if they don't have money to buy food in the market. In their own back yards or on land in their local communities, they can get the nutritious greens they need for their families.”

Food has become a serious need to the Philippines as COVID-19 hit the country. Their government and communities have started a “community gardening" project to recover from the situation.

One of the founding mothers of the Homeless People’s Federation of the Philippines, Ofelia Bagotlo, describes how community gardens on vacant city plots are providing vital nutrition for the urban poor.

"Governments should consider establishing a new, multilateral, United Nations-led Food Systems Stability Board," says Sandrine Dixson-Declève, co-president of the Club of Rome and the former CPO of UN Sustainable Development.

Madagascar is on the brink of experiencing the world's first "climate change famine", according to the United Nations, which says tens of thousands of people are already suffering "catastrophic" levels of hunger and food insecurity after four years without rain.

The food price spikes demonstrate how extreme weather, much of it caused by the climate crisis, is having a real-world impact on Americans. And climate scientists warn the fallout will only intensify from here.
Climate change is coming right into our dining room tables, Cynthia Rosenzweig, adjunct senior research scientist at the Columbia University Earth Institute, told CNN Business.

A dietary shift from rice to potatoes could “notably reduce” the climate and environmental impacts of staple crop agriculture in China, according to a new study.

The research, published in Nature Food, examines the land use, water use and greenhouse gas emissions associated with growing four staple crops: rice, wheat, maize and potatoes. It finds that a large-scale dietary shift towards potatoes, combined with better growing methods, could reduce the greenhouse gas emissions of these staples by up to 25%.

Once-unthinkable water crises are becoming commonplace. New data from WRI’s Aqueduct tools reveal that 17 countries—home to one-quarter of the world’s population—face “extremely high” levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year. Forty-four countries, home to one-third of the world, face “high” levels of stress, where on average more than 40% of available supply is withdrawn every year.

Water Stress is not your destiny. Like any challenge, its outlook depends on management. Even countries with relatively high water stress have effectively secured their water supplies through proper management.

In any geography, water stress can be reduced by measures ranging from common sense to cutting-edge. There are countless solutions, but here are three of the most straightforward.
