The dictionary defines food as 'what one takes into the body to maintain life and growth'. It goes without saying then that everyone has to eat to live.

According to the United Nations World Food Programme (WFP) there is enough food in the world today for every man, woman and child to lead healthy and productive lives. Even though the world's population has grown 6-fold in the past 200 hundred years, food production has grown even faster thanks mainly to modern machinery, hybrid seeds and better fertilisers. And with the advent of precision farming, which ensures that each plant gets just the right amount of water and fertiliser for maximum yield through the use of drones, satellites, robots and large-scale data collection, this looks set to continue. Precision farming also has the potential to reduce fertiliser use whilst allowing farmers to adapt to the effects of climate change according to Mark Rosegrant, a director of the International Food Policy Research Institute (IFPRI),

In the last 20 years farm production has increased by 260% with 2% fewer inputs. This means that there is now 17% more food available per person than there was 30 years ago. Today, it is estimated that 12% (1.6bn hectares) of the Earth's land surface is under crop production and 33% (2.5bn) of people) worldwide depend on farming to support themselves.

However, according to the UN Food and Agriculture Organisation (FAO) one third of all food produced in the world - approximately 1.3bn tonnes per annum - goes to waste due to a combination of situations ranging from, amongst other things, problems with harvesting, storage and transportation.

In the rich countries of the North, where individually we spend on average £9 (US$12) per day on food, the supply and variety has never been better. Visit any supermarket and you will find shelves stacked with affordable produce from all over the world. And coronavirus notwithstanding, going out for a meal too, in our towns and cities, affords us a choice of restaurants which serves dishes and drinks from every continent. As a result, on average, most people in the North exceed the FAO recommended daily minimum intake of 1,800 kilocalories a day by some distance.

Yet, on the other side of the globe, in the South, life could not be more different. Here most people are subsistence farmers often eking out a perilous existence using methods of farming that have barely changed through the centuries. Bad harvests are a continual hazard in this part of the world where some 54 nations (37 in sub-Saharan Africa) are low income countries that do not produce enough food to feed their people. And the problem for these countries is that although there may plentiful supplies of food in the world for everyone's need, politics, greed and indifference, all too often, stand in the way of getting surplus food to where it is often desperately needed.

The most self-sufficient country in the world in food production is Argentina which produces 273% of its own food. The country least able to feed itself is Zimbabwe which produces just 54% of its requirements as a result of the forced take-overs of farms owned by whites (skilled workers) 20 years ago. In 1980 Zimbabwe was the bread-basket of southern Africa.

According to the Global Hunger Index compiled by IFPRI 871m* people (1 in 9 in the world) go to bed hungry every night - including 1 in 4 living in sub-Saharan Africa. Here 19 countries are suffering from levels of hunger that are either 'alarming' or 'extremely alarming' with the worst affected countries being Central African Republic, Chad, Liberia, Sierra Leone, Sudan, Madagascar, Niger, Zambia and Zimbabwe: North Nigeria is also a problem. At the same time, Burundi, DRC, Comoros, Eritrea, South Sudan and Somalia were among 13 countries excluded from the index due to lack of data.

(*2020 is the fifth year in a row that world hunger has risen.)

There is more food for thought though for nutritionists reckon that the same amount of people again suffer from a hidden hunger - a lack of sufficient micronutrients which are vitamins and minerals that support physical and mental health.

Conflict is another major driver of hunger. The UN estimates that 100m people in the world suffer in this way.

Taken together, across the world today, 21,000 people die daily from malnutrition and hunger-related diseases - many of them children under 5. That means that the lack of food/malnutrition kills more children in the world today than any infectious diseases, war or natural disasters yet it remains a 'silent emergency' arousing little public concern until the next emergency is thrust onto our TV screens.

In contrast, in the North, a combination of over-abundance, changed eating habits, lack of money and less-active lifestyles has led to a situation where a large proportion of the population is overweight or obese**. For example, today in the US, according to the World Health Organisation (WHO), it is estimated that 70% of the population is overweight including 42% who are obese which includes 9% who are severely obese. (Even President Trump is considered obese!) For the UK*** the figures are 64% and 26% whilst 1 in 10 children are considered obese when they start primary school rising to 1 in 5 when they leave. All of which creates a significant public health challenge = in 2018-19 there were an estimated 876,000 hospital admissions in England where obesity was a factor, an increase of 23% on the previous year. (In 1960 only 2.5% of Britons were obese, 6% in 1980 and 15% in 1993) The UK is the most obese nation in Western Europe. In comparison, in Japan, the obesity rate is just 4% where the diet is rich in rice, vegetables and fish.

More than half the world's population today lives in cities and this urbanisation has caused a rapid shift in diet and lifestyle, with more processed foods and less physical activity. At the same time, according to UNICEF, not a single country in the world has made progress in decreasing levels of overweight and obesity in the past 20 years.

(Britons drink more alcohol than most other OECD countries. Annually, adults drink 9.7 litres of pure alcohol which equals 108 bottles of wine or 340 pints of beer/lager. That is almost a litre more than the OECD average of 8.9 litres and higher than consumption in Italy, US and Australia. But not as much as France and Germany. Lithuania is the heaviest drinking nation with 12.3 litres whilst Indonesians drink the least.)

The Department of Health estimates that 80% of weight gain in the UK is caused by overeating/over indulging in the wrong type of foods and by low levels of physical activity. In the UK this 'extravagant' lifestyle in turn leads to an estimated 33,000 premature deaths annually at a cost to the National Health Service (NHS) of £9bn (US$12bn). And this 'epidemic' also has the knock-on effect of 22m days being lost every year in the work place through sickness leading to a loss of output totalling £2.5bn (US$3.3bn). According to World Health Organisation (WHO), unless something changes fundamentally, by 2030, 70% of the UK population will be overweight or obese. (In total, 1.9bn adults in the world are overweight whilst 672m adults are obese, triple the figures for 1975.) At the same time, in the UK, rates of childhood obesity are more than twice as high in the pooorest areas where there are five times more fast food restaurants than the most affluent areas.

The changes needed, say experts, are for the government to restrain the food industry by taxing fizzy drinks/fast food, removing vending machines from schools and taking junk food out of hospitals and government offices. And you and me need to cut down on portions! (However, this is a really tough challenge for in a recent study conducted across 22 countries it was found that for every advertisement for healthy foods there were four promoting unhealthy foods!)

At the same time we should try leaving our cars at home more and walk or cycle to our intended destination. The average car journey is only 8 miles with 25% of these journeys less than a mile. And for those already using public buses why not start by walking to the next bus stop and then, in a week, the next one after that!

(Taxes on red meat could also be considered for that would reduce consumption, improve diets, reduce greenhouse gases from livestock and lead to the freeing up of more land for crops.)

Being overweight, it seems, is now becoming more prevalent in the developing world too. According to the Overseas Development Institute the number of obese and overweight adults in the South has almost quadrupled in the last 30 years to around 900m which added to those in the North means that one quarter of the world's population is now overweight.

However, it is the often acute food shortages in the South that should be given priority.

To start with surplus food supplies from the North urgently need to made available to countries where there are desperate shortages. Politics should not be played with hunger and starving people need immediate help. But this should not be seen as a permanent solution as shipping food will not improve the prospects of the world's hopelessly poor, three quarters of whom live in rural areas.

At the same time governments in developing countries need to allocate more than the current 6% of their national budgets to agriculture. In 2003, in the Maputo Declaration, African leaders committed to allocating 10% of their national budgets to agriculture. However, fifteen years on just 7 countries - Burkina Faso, Ethiopia, Guinea, Malawi, Mali, Niger, and Senegal - have reached or exceeded the 10% target whilst 9 countries - Angola, Eritrea, Ethiopia, Burkina Faso, Congo Republic, Gambia, Guinea-Bissau, Nigeria, Senegal and Tanzania - have reached growth in agriculture of more than 6% p.a. And so still today in Africa, bizarrely, even with an average of 6% of national budgets allocated to agriculture more money is wasted on defence on a continent where almost 75% of the population is engaged in subsistence farming.

Even with this huge presence on the land, food security continues to remain elusive with many farmers barely able to produce enough food for their own families never mind having any left over to sell. Yet Africa's farmers, who are mainly women working on tiny plots, could grow approximately three times more food if they had more government support in gaining access to essential inputs: fertilisers, pesticides, irrigation and access to local agricultural expertise. And this would not only be a good investment in farming it would also help reduce Africa's annual food import bill of US$35bn on the continent with the largest amount of rain-fed uncultivated land. Moreover, as 65% of agricultural land in Africa is degraded, being allowed access to genetically modified (GM) seeds would also make an enormous difference to food production whilst cutting down on toxic pesticide sprays. Currently, however, due to the machinations of the European Union, green campaign groups and many churches, the advent of GM crops is all too often resisted by those in authority in Africa.

Farmers also suffer from not owning their own land which makes it impossible for them to put up security in order to borrow money to help bring about improvements. As such, one of the first tasks for governments and state authorities in the South should be to try to work to vest every farmer in the title to his/her own land. In this way the home/farm could be used as security to borrow money for better seeds, fertilisers, tools and machinery which would lead to a big increase in crop production. However, native customs, where all tribal land is vested in the chief, can make this a challenge in many parts of Africa.

Farmers could also be encouraged to amalgamate their small plots into co-operatives. (Currently 80% of farms in sub-Saharan Africa are smallholder-family concerns performing at about 40% of their potential) Co-operatives would allow machinery to be bought making life easier for those working the land. In turn this should boost production leaving larger profits to be shared according to the size of land contributed and the hours of work put in. Having certificates of ownership in a co-operative would also allow other farmers to join in and allow those wanting out the means to do so. Coming together like this would also help those families where the bread winner is no longer there or incapable of work. It would also allow children to get back to school instead of having to work in the fields in order to help their families maintain food production.

(According to experts growth in agriculture is up to 11 times more effective at reducing poverty than increases in any other sector. Also 60% of the world's unused agricultural land lies in Africa.)

The main cause of food shortages in poor countries is usually blamed by governments on drought but all too often this can be used as an excuse. Nobody disputes that hunger is aggravated by bad weather but according to a blog from IFPRI in July 2017 'ending famines and chronic hunger requires good governance.' For example, in many parts of Africa water is readily available in countries lacking in food but too many governments either through neglect, alternative priorities, incompetence or lack of finance are not using the water resources available.

Take Ethiopia, for example. Until recently, water from the Ethiopian Highlands, and the huge expanse of Lake Tana, was hardly tapped at all by a government more concerned about arguing over a worthless town in a useless piece of desert on its border with Eritrea. This was apparently considered more important than encouraging farmers to move to more fertile parts of the country where irrigation channels, bore-holes and wells could be constructed to provide water for all their needs. Thankfully this is all about to change with the completion of the construction of the Grand Ethiopian Renaissance Dam, an impressive hydropower project, which will be the continent's largest. Similar potential lies in the Congo River if the will is there!

Transport is also a problem. A recent World Bank study found that high transport costs in Africa were driven just as much by poor regulations as by bad roads. (Only 16% of roads in Africa are paved.) Current regulations impose substantial barriers to entry thus allowing existing transport companies to maintain a monopoly and charge high prices.

Joined-up government is essential for moving food supplies within a country. And here again Ethiopia suffered from government inertia in the past. A combination of poor communication, inefficiency and corruption across the country meant that even in good years surplus food lay rotting in one part of the country whilst people starved in another. But even when the message did get through there were few roads in Ethiopia and most of them were potholed big time. So moving grain around the country could be perilous and costly as can be seen from the experience of one enterprising grain merchant who tried to take a truck load of grain from the south to the north of the country.

The journey of 900k (560 miles) meant 17 days on the road to reach his destination. In that time he was stopped 10 times by local officials whom he had to bribe in order to be allowed to move on. And at the end of his ordeal he found that the roads had been so rough that many of his grain sacks had burst open. However, his problems didn't end there. Selling in Ethiopia was also made hazardous by the fact that there was no legal system to enforce contracts and very few traders had bank accounts. As a result vendors could only sell for cash and buyers had to inspect and weigh every bag of grain to ensure that they hadn't been cheated. So as he couldn't find a trustworthy trader prepared to pay in cash he finished up literally giving what was left of his load away. Needless to say that grain merchant is unlikely to undertake such a journey again.

At one time more than 20 million Ethiopians were still facing chronic food shortages but this is changing. In 2010 large-scale public and private investments in agricultural research and the promotion of fertilizer use led to substantial gains in cereal production and the availability of food. At the same time infrastructure investments such as improving and expanding road networks are helping to effectively move crops from farms to markets. Together these investments have helped smallholder farm households to achieve higher yields and production, raising their incomes and access to food. Additional programmes including terrace building to reduce soil erosion and education on nutrition have also helped stave off hunger.

(Ethiopia is the birthplace of Arabica coffee which tends to be grown in the cool, humid highlands. With temperatures steadily rising in Ethiopia this is now damaging the crop forcing new plantations to be created on higher ground where the climate is cooler and wetter. Ethiopia is the 5th largest coffee producer in the world employing 15 million farmers and makes up a quarter of the country's export earnings.)

However, often exacerbating the food situation in Africa are foreign governments and large international corporations, mainly from India, the Orient and the Gulf, seeking prime agricultural land to grow food for their own people back home. And African governments, it seems, are more than ready to oblige. At the forefront here again is Ethiopia where it is estimated that the government has leased or sold 10 million acres of prime farmland to foreign investors since 2008. In order to achieve this the government has forcefully removed tens of thousands of people, with no compensation, onto marginal land where they are left to fend for themselves. And there they continue to eke out a living whilst fruit and vegetables worth an estimated US$250m per year are exported. So the government may have upped food production in Ethiopia but at the expense of many farming families.

Other countries which have already leased/sold land to foreign entities include Sudan with 4 million hectares, DRC 2.8m, Mozambique 2.7m, Mali 2.0m, Zambia 2.0m, Cameroon 2.0m, Liberia 1.6m, Benin 1.2m, Sierra Leone 1.1m with many of the deals going through at rock-bottom prices. And in the cases of Benin and Sierra Leone Oxfam calculates these figures represent 34% and 32% respectively of total agricultural land in these countries.

African governments should have laid down certain conditions before ceding land to foreign entities:-
1. all of the people whose land was requisitioned should have been compensated and given alternative land.
2. 90% of those employed on each project should be locals.
3. 50% of the food produced should remain in the country.

It could be argued, however, that the selling of land to foreigners helped to dispose of one government in Africa. In March, 2009, in Madagascar, Andre Rajoelina overthrew the government of Marc Ravalomanana after he promised to lease half the fertile land in the country to Daewoo, the South Korean conglomerate.

All of this means that food aid will continue to be important if mass starvation is to be prevented, not just in Africa, but around the world. In 2018 WFP provided food assistance to around 86.7 million people in 83 nations most of whom were were women and children. At any one time WFP has 20 ships at sea, 92 aeroplanes in the sky and 5,600 trucks on the ground moving food and other assistance to where it is needed most.

Some UK food facts:-

According to Wrap, the UK waste-reduction charity, families are throwing away £810 worth of food a year on average. In the average home a quarter of a tonne of food a year, the equivalent of 500 meals, ends up in the rubbish bin. Half the waste results from food not being eaten before its use-by date and the rest is from cooking or serving too much. Food and drink waste in households rose from 7 million tonnes in 2012 to 10.2 million tonnes in 2018.

Perhaps the main reason for this is our misinterpreting of supermarket labelling. Display until is only for supermarket information; best before means what it says that the food is best consumed by the date indicated but can still be used after that; use by is the date that should be heeded and the food recycled or thrown away after this expiry date. However, life can be prolonged even here if the food is frozen before the 'use by' date.

Britain's biggest supermarkets have signed up to the Courtauld Commitment 2025 in a campaign that aims to tackle the estimated two million tonnes of food wasted every year in the UK. As such Tesco, Sainsbury's, Morrisons and others will try to double the amount of surplus food they redistribute in a new drive to give to charities which help the poor. Tesco has even made the aim that no food that is safe to eat will be wasted inside Tesco UK supermarkets.

REfUSE, a branch of the Real Food Project in Chester-le-Street in Durham in the north-east of England uses perfectly good food that has been wrongly labelled 'worthless' due to over-ordering, strict cosmetic standards, damaged packaging, incorrect labelling, best-before dates, cancelled orders etc. Then, through the help of volunteers, they have opened up a cafe on the basis of Pay As You Feel. Anyone, including the homeless/refugees, coming in for food/drink can pay in cash or help wash up, play music or blog about the cafe to pay for their meals. The food is donated by local shops, supermarkets, restaurants, wholesalers and from allotments. The Real Food Project adhere to all the Environmental Health regulations and have a 5* Food Hygiene rating. Any profit made goes back into expanding the business. Surely a practical solution by very dedicated people to a shameful problem that could be adopted across the country and beyond. see

In a study by the University of Aberdeen more than 18 million acres of land in foreign countries is now used to grow crops either consumed directly by Britons or fed to British animals that produce meat and milk. This is exactly double the amount of land used in the UK for growing crops and shows Britain is much more reliant on imported food than government official figures show. This comes after a warning form the UK National Farmers Union which accuses successive governments of displaying 'dangerous complacency' over the country's ability to feed itself.

(**A healthy weight range is based on a measurement known as the Body Mass Index (BMI). To calculate your BMI you divide your weight in kilograms by your height in metres squared. The ideal weight is a reading between 20 and 25 but you are underweight if it is below 20. Between 25 and 30 people are considered overweight and above 30 you are classified as obese.)

(***It is estimated that more than 8 million people in the UK live in households that struggle to put enough food on the table, according to estimates by the Food Foundation. And with growing numbers of people using Trussell Trust food banks hunger in the UK is perhaps more widespread than it might appear.)
