STOP FOOD WASTE: THE FUTURE IS AT RISK, THINK 2050



There has been growing concern globally on the way we live in different regions across the world and the global crisis that looms if current individual and collective actions are not corrected.

Food waste or food loss is any food material that is discarded or unable to be used. In the context of this presentation, we will need to refer to this as not been used judiciously. It is also important to note that food waste comes in chain and in cycles which affect every region of the world in line with their lifestyles, standard and local belief systems.

Roughly one third of the food produced in the world for human consumption every year (approximately 1.3 billion tonnes) gets lost or wasted. This is an alarming loss percentage that we all should get worried about and understand food is not just the cost of the food wasted; but cost of other variables in both direct and indirect cost. 

Every year, consumers in rich and developed countries waste almost as much food (222 million tonnes) as the entire net food production of sub-Saharan Africa (230 million tonnes). If this volume of food wasted can be saved, it means it could almost feed a sub-region in Africa for a whole year and this gives me a whole lot of reasons to get even worried the more. 222 million tonnes of food waste is no joke.

In developing countries food waste and losses occur mainly at early stages of the food value chain and can be traced back to financial, managerial and technical constraints in harvesting techniques as well as storage and cooling facilities. This is a peculiar food waste control gap that is peculiar to developing countries but this can be strengthened if farmers and food producers can have the confidence and support of government through investment in infrastructures such as good storage facilities, transportation for moving food and food products, expansion of food and packaging industries, reliable electricity, all these put together can reduce considerably the amount of food loss and waste. Invariably, the food waste in developing countries is more in the production chain than in consumerism.

This does not ultimately rule out the fact that we also have food waste at the consumer’s stage in developing countries. This is mostly associated with cultural belief systems and life style of the people. I live in Nigeria in Africa where visitors must be fed before they leave irrespective of whether they are truly hungry or not. We most times serve such visitors more than enough food that they could ever finish, we end up having leftovers that may never be eaten but thrown to the dust bin. What we need to know is that as we are busy wasting those food, there are millions of children across the world that have no food to eat and languishing in malnutrition. Food is too good to be wasted, we need to stop this trend and we need to reduce food waste now so we can prepare for possible future food shortage.
  
In medium and high income countries, food is wasted and lost mainly at later stages in the supply chain. Differing from the situation in developing countries, the behavior of consumers plays a huge part in industrialized countries. This dynamics could be seen to have some underlying social economic status factors, people shop for and most times cook more food than they need and bulk of these food never get to the dinner table. 

Most potent way of dealing with food waste is to reduce its creation. Consumers can reduce their food waste output at points-of-purchase and in their homes by adopting some simple measures good enough to stop food waste no matter how small. This includes planning when shopping for food and spontaneous purchases are shown as often the most wasteful. Proper knowledge of food storage reduces foods becoming inedible and thrown away, infrastructures also play a key role in this direction.

In the United States 30% of all food, worth US$48.3 billion, is thrown away each year. It is estimated that about half of the water used to produce this food also goes to waste, since agriculture is the largest human use of water (70%). (Jones, 2004 cited in Lundqvist et al., 2008)

United Kingdom households waste an estimated 6.7 million tonnes of food every year, around one third of the 21.7 million tonnes purchased. This means that approximately 32% of all food purchased per year is not eaten. Most of the food waste (4.1 million tonnes) is avoidable and could have been eaten had it been better managed (WRAP, 2008; Knight and Davis, 2007).
 
In the USA, organic waste is the second highest component of landfills, which are the largest source of methane emissions. Methane is one of the most harmful greenhouse gases that contribute to climate change. Methane is 23 times more potent than CO2 as a greenhouse gas. The vast amount of food going to landfills makes a significant contribution to global warming, this clearly states that the impact of food waste has both environmental effect through the use of chemicals such as fertilizers and pesticides, more fuel used for transportation, land use and cost of all these which has an overall financial impact. 

We also need to consider other associated impact food waste has on water. We already know that agriculture already has the largest human use of water which is put at 70% (around 550 billion cubic metres of water is used to grow crops that never reach the dinner table), before we waste food we should also think of the impact this waste is going to have on water also.
In a document released by Food and Agriculture Organisation (FAO) “Food Waste Footprint” it was stated that under current production and consumption trends, global food production must increase 60% by 2050 in order to meet the demands of the growing world population. The current world population of 7.2 billion is projected to increase by 1 billion over the next 12 years and reach 9.6 billion by 2050. This means by 2050, we have an extra 2.4 billion mouths to feed and this will also place more demand on water needed for food production.

Food waste comes in different stages and cycles which range from:

  • Food waste in harvesting processes which is more in mechanised farming
  • Food waste through economic factors such as regulation and standard which leads to selective harvest that leaves food that does not meet market standard unharvested and left to waste in the farm.
  • Food waste through processing otherwise known as post harvest loss with loss ration relatively unknown and difficult to estimate
  • We also have a level of food waste in post harvest stage and this is more evident in storage. This loss is classified into two namely:
  1. Quantitative loss: This loss is attributed to pest and micro-organisms that affect the stored food which leads to reduction in quantity eventually available for human consumption.
  2. Qualitative loss: This is more in areas that have a combination of ambient heat and humidity which encourages the breeding of pest and micro-organism. This reduces the nutritional value, caloric value and edibility of crops. In a market that has standard and effective regulation, this food could also be affected and perhaps have little or no market value and ultimately disposed as waste.
  • We also experience high level of food waste through retail stores where large quantities of food are thrown away. Usually, this consists of items that have reached their either best before, sell-by or use-by dates. These foods are destroyed by retail stores. It is important to note, these retails stores also shift the food waste to consumers by sales strategy on products with low shelve life or about to expire. Such strategies include 50% price reduction or buy-one-get-one-free, this attracts buyers to buy more than they need or buy what they do not even need which ends up most times as waste in dust bins.
  • Suppliers to retail stores also produce or stock more food and food products than would be needed for supply to these stores based on contractual agreement, the excess that are perishable are afterwards thrown away.
When we weigh issue of food waste in several balances it does not favour the world in any way and changing the trend needs individual contribution. You need to take a personal pledge while I take mine irrespective of the part of the world we differently live in, we need to stand for this and conscientiously adopt food saving strategies for the sake of the future of the world. Children in different parts of the world are ravaged by poverty and hunger, the absence of relative peace due to widespread of wars and regional conflicts across Africa and some other parts of developing regions also lead to a number of children being orphaned. We also need to understand the concept of globalization which has removed trans-border barrier which leads to ease of migration by citizens of different countries that are either hit by national conflict or poverty. There are currently 9.7 million worldwide refugees according to United Nations High Commission for Refugee and these people take refuge in different countries or cities and remember we need food to feed this mass of people. 

When you take a position to contribute to the global campaign against food waste in your country and we all do same in our different countries, we would make the world a better place. No one individual can do this alone, when we all come together it means we all have the strength to make it work. If one can save a plate of meal to feed one and another saves a plate of meal to feed another, we will together be able to feed our growing population through the collective efforts of you and I. This is the way forward; it is the right thing to do.

Take a stand today and make it count, our collective decision is an investment for a sustainable global population.

HIV/AIDS INFECTIOUS DISEASE: THE TRENDS, FACTORS LEADING TO CHALLENGES AND THE USE OF GLOBAL PUBLIC GOODS APPROACH



HIVAIDS is an infectious disease listed amongst the big 5 infectious disease burden in the world. Over 35 million people have lost their lives to the global HIV epidemic with 42 million estimated people living with this dreaded infectious disease. Developing countries has estimated 90% of the global pandemic with sub Sahara Africa region being the world worse affected region with already over 12 million children already orphaned by the disease within the region and it was postulated to increase to 18 million in 2010.

What is most shocking is the increase in the prevalence of HIV infection globally in spite of the huge fund that has been globally committed to the fight against the scourge. The high income countries of the world have been able to build feasible capacity with support from Global Partners and a combination of political commitment to fight the scourge. The reverse is the case in the low income countries bracket; it has become a combination of poverty, disease, political and economic instability and weak health infrastructure which has duly hindered remarkable progress in effort against HIV AIDS.

Despite of increase in available resources to tackle the prevalence of this disease, most regions such as sub-Sahara Africa, Eastern Europe, and Central Asia are still accounting for intensifying increase in the scourge with approximately 79% of new infections between 1998 and 2003. It is most pathetic that a greater number of people living with HIV/AIDS are in sub-Sahara Africa with equal concern of growing epidemic in Central Asia. A number of reasons are responsible but numerous amongst them are:

The social economic status of the people: This is a combination of different variables. A poor population ravaged by HIV infection will over time be wiped away if early intervention does not come their way and this was the case of some peculiar regions as Africa and Asia with very high population but low per capital income. Within the high income countries, the support from government and global partners is robust and with the level of fund allocated to enlightenment coupled with the improved per capita income, it looks a little better than what’s available in the developing countries.

If you recall, the cost of ART was exorbitantly high and was not within the reach of the purchasing power of the infected population. It even became more complicated when these regions had no structured health financing systems instead everyone pays for their healthcare treatment from their pockets each time they receive treatment at the hospitals. This was a huge burden in some regions that did not allow for effective management of HIV infection even when detected, the inability to continuously procure drugs and even maintain quality and healthy meals were a great concern in developing countries where some infected cases deteriorated to having tuberculosis alongside. This is evident in the way the infected people look coupled with the social stigma attached to the disease, there are virtually no one to offer help to these sets of infected patients, they are either manage themselves as much as they could and die on the long run predominantly without the needed care.

It was really bad that people stop associating with you immediately they discovered you have HIV infection, even the family members assign specific feeding plates to them, they are confined to certain parts of the house, their meals are sneaked into their rooms with disgust, toilets are no longer shared with them etc. These were the challenges that fast killed the infected patients outside the virus itself.

With the globalization and the new information available across the world, people are able to declare their HIV status publicly, the acceptance is quite impressive nowadays, the drugs are more affordable now and even the prescription and treatment outcome are quite impressive.

Sexual behaviour: Despite the advocacy surrounding the infectious nature of the HIV/AIDS disease, there still exist a huge belief in some of these poorer regions that the disease called HIV/AIDS does not exist and this has encouraged a certain proportion of the population to still take to careless sexual behaviour without condoms, having multiple sex partners and even commercial sex workers and their male patrons. This brings about a chain reaction from the sex workers infecting their male partners and the male partners in turn infecting their female sexual partners or spouses. This has created a web of challenge and difficulties in the global efforts invested towards fighting HIV AIDS.

The concept of globalisation which has removed the trans-border barriers is also a very strong factor contributing to the spread of the disease. Migration through international travel has been credited also the spread of sexually transmitted diseases including HIV, refugee population arising in areas of conflict is not excluded in these factors. There are currently 9.7 million worldwide refugees according to United Nations High Commission for Refugee and these people take refuge in different countries or cities resulting into cross border disease transmission.

Even in most countries, there are a number of high mobility internal labour migrants who mostly move between the urban and the rural communities, these are very possible ways diseases also travel within a nation and between communities of population groups. 
  
Gender inequality and gender bias in some regions as Africa where women are rated very low and used as sex tools has also been an issue of concern. Studies have shown female are more at risk of contracting HIV than their male counterparts. In 1997, women accounted for 41% of people living with HIV worldwide and in 2002, the figure rose to almost 50%.The impact on women though less marked in Asia, 28% of those infected are women but women’s low socio-economic status renders them more susceptible to infections. This women’s increased vulnerability to HIV Infection was not confined to developing countries only neither was it exclusively an issue of poverty. Between 2001 and 2003, the percentage of HIV infected women rose from 20% to 25% in North America and in Oceania for 17% to 19%. The further buttress the point that gender inequalities is associated with the spread of HIV. 

The absence of relative peace due to widespread of wars and regional conflicts across Africa also led to a number of young women and girls getting raped and sexually violated in war torn countries as Liberia, Rwanda, Ivory Coast, Sierra Leone, Somalia etc and these also contributed to the spread of HIV infection.

Some of the early challenges which also posed initial problems across some developing regions as Africa were lack of enough information and clearly defined advocacy programs. Because of this paucity of right information, people chose to believe whatsoever they are told about HIV even if it is utterly wrong. This brought about different interpretations of the acronyms (AIDS) in some parts of Nigeria, younger people trivialised it and tagged it American Invention to Discourage Sex (AIDS) and in the midst of all these confusion and misconception, there was no strong political commitment on the part of Government to take ownership of a strong advocacy and public enlightenment processes, this was the case in many regions across Nigeria and other parts of sub-Sahara Africa. The younger population in high schools and colleges yearned for the right information which was in scarce content and were sometimes aired in between network news on Television at 9.00pm when more than 50% of Nigerians in many regions had no access to electricity let alone television to access such information.

Hospital and healthcare facilities did not have the requisite capacity rather to help people who came with honest intentions to be educated on HIV infection. It was wrongly classified as an issue that has to do exclusively with sex and this made people stay away from sex and continue to share sharp objects which has great potentials to getting them infected. There were absence of HIV counseling centres and no sexual health education in schools and communities, these led to limitation in available information that will be of help to the population.

Even the nurses and the entire healthcare workers did not have protection neither were there care workers prevention guidelines so they were not also excluded from the chain of spread of HIV infection. Do not forget most of those Nurses, Doctors, Phlebotomists and everyone in the healthcare chain that has anything to do with patient’s blood and other potentially infections materials were all vulnerable and had sexual partners or spouses also.
One of such local determinants that contributed to the challenge in developing countries is the local belief system, use of local herbs and traditional medication. Outside the fact that they did not open their mind to accept the existence of the pandemic, they even believed that even if it does exist they have enough herbs to achieve outright treatment and cure. The infection found its way in through internal migration and yet people died with perhaps symptoms of AIDS but we refused to agree that it was AIDS disease living with us. 

If you recall, a number of Nigerians (Medical Doctors and Herbal Doctors) came up with the false claims that they have discovered cure for the HIV AIDS and most people who suspected they had this infection went quietly and secretly to those Doctors who deceived them and collected their money and left them to die.  

Since the adoption of global public goods approach, there have been tremendous milestones in terms of achievement in finding useful solutions in addressing this issue.
Some of such profound approaches adopted were the funds allocation to research and development to enable researchers come up with new medicines to combat and prevent these diseases. This made the pharmaceutical companies have access to funds to research on relatively new areas and also to conduct trials at different stages for possible clinical approvals.  

There was also the convention on Intellectual Property Rights (IPR), most importantly the DOHA declaration on the TRIPS agreement. These efforts gave room for the outcomes of research and development that has been approved to be shared and used for the good of all instead of placing restrictions in form of patents and copyrights that makes these research breakthroughs exclusively products or efforts of a few people who the world must pay so much to benefit from. The interventions made by the WTO gave room for other pharmaceutical companies (multi partner collaborations) to use the same research to come up with other generic brands of drugs that are more affordable and efficacious. This was a very useful instrument in ensuring access to treatment within and between low and middle income countries who per capital income could hitherto not grant them access to medications. This approach has also led to treatment simplification, it has reduced 10 pills taken 3 times a day in 1996 to 1 pill combined in all treatment taken once or twice daily in 2006. Virtually all hospitals and health centres have access to these drugs and it has given respite and hope to those living with HIV infection. The introduction of the male condom and lately the female one has also been an achievement in this direction coupled with the fact that counseling centres now have access to new information to help people on HIV infection. 

We can see in recent reports that over 8 million people now have access to treatment and over 60% of people needing treatment in developed countries now having access to treatment.
