Rising to the Challenge: Changing Course to Feed the World in 2050. Farming of fish occurred over two millennia ago with the Chinese and Romans. With 9B Mouths to Feed by 2050, We Have to Get Busy Now Feeding the world of tomorrow is technologically feasible with existing tools (and some creative thinking). Step Four: Shift Diets. It is projected that by 2050, the total world population will reach 9 billion (The World Bank 2016) and with the accompanying growing demand for more food, many challenges need to be addressed concerning food sustainability. World Food Supply in 2050 through Sustainable Solutions F.A.O. More crops will be used as food and probably less for animal feed. The UN’s FAO believes that they can. Dr TONY ANDREWS concludes his discussion of the challenges facing food producers in feeding an everexpanding global population, and the role veterinarians will play in achieving sustainability. An example of perhaps a suitable technology might be the erection of multi-storeyed buildings in cities and elsewhere to maximise hydroponic (now sometimes called aquaponic) systems to rapidly produce large quantities of highly digestible plant crops for both man and animals. 349 7028 73. If some of these numbers are even roughly correct, it will mean the need for an increase in areas used for wheat production, greatly improved, suitable and effective technology, higher yielding plants (currently typical yield rise from plant breeding is 0.04% per year), effective pesticides and their intelligent targeted use, more efficient herbicides and their targeted use, efficient harvesting and storage of cereal and straw. These solutions require a big shift in thinking. How to Feed the World by 2050: Biotech Isn't the Answer. Whilst this may occur, it illustrates the need to produce local technical answers rather than global ones. “By 2050, the world must feed many more people, more nutritiously, and ensure that agriculture contributes to poverty reduction through inclusive economic and social development, all while reducing greenhouse gas (GHG) emissions, loss of habitat, freshwater depletion and pollution, and other environmental impacts of farming,” the report states. In the case of herbivores and omnivores, while some are likely to be reared outside, others will spend some or much of their time indoors. The world faces the looming challenge of feeding an expanding population that is expected to reach 9 billion by , from just over 7 billion today, while climate change increases uncertainty. But a new report found that it will be impossible to feed them all without major changes to the global food system. Farmland is already degraded by existing agriculture, and climate change is putting new pressure on crops and livestock. Many parts of the world have developed animals which are able to cope with their specific local environment. Andrews, A. H. (2014) Major factors influencing 2050 world food production – 2. If the world is to feed 9 billion people in 2050 and successfully navigate ecological tipping points in the face of climate change, solutions such as the above will be needed on a global scale. That’s a lot of mouths to feed, ... the world’s population is expected to reach a whopping 9.7 billion by the year 2050. The extrapolations are based on changes occurring with a country’s increase in gross national production and this has previously been argued as unsustainable on a global basis. Growing and harvesting plants and cereals correctly could meet world needs if there is the political will to do it. There will be a need for increased water availability and this has been discussed in the previous article (Andrews, 2014). Solving this serious problem will require input from the brightest minds in every industry. What do people think are the obvious/not obvious solutions to 'feeding the world in 2050'. It means an annual increase in wheat yield of towards a tonne, but calculations have predicted that the rise will only be 10% due to the increasing CO2 levels (Abel, 2014). Figure 1. How Will We Feed the World in 2050? If problems with pollution and disease can be overcome, producing fish (sea and fresh water) and other types of aquaculture can probably be more easily increased than land production. Efficiency: When there isn’t more space to expand Food production is a major contributor to climate change, which means expanding agricultural land to feed the world in 2050 is not a sustainable solution. Thus, there are many areas where pasture is the most productive or only crop that can be successfully grown. ... but fish farms also tend to catch wild fish to use as feed. We have made this change to fit in better with our international partners’ schedules. Although many of the fish currently farmed are carnivores, other fish are vegetarians and breeds such as the tilapia are already being raised in South America and Asia. Yet, if the world is going to feed an estimated 40 billion livestock and poultry by 2050 in a sustainable manner, further efficiency in animal nutrition will be necessary. If food trends continue unchanged, 593 million additional hectares of land, equivalent in size to two Indias, would have to be cleared and converted to crop and livestock production to feed … These do not necessarily take into account that inputs in the various parts of the food chain can be altered or often there are mitigating factors which may modify GHG or other factors which are not considered as being as important as the calculated footprints. Besides saltwater fish, there is the potential to produce more freshwater fish. CRISP-R technology or gene editing is a way of selectively breeding a plant to get desired traits like higher yields or drought resistance. It should be possible to supply adequate amounts of food providing politics do not impede its production and movement. Extent, Causes and Prevention; pp1-15. To gain more understanding about the problem of feeding the world in 2050, we asked scientists, engineers, economists, architects, and journalists—people at the forefront of research and reporting on this issue—for their ideas and advice. Scarborough, P., Appleby, P. N., Mizdrak, A. et al (2014) Dietary greenhouse gas emissions of meat-eaters, fish-eaters, vegetarians and vegans in the UK. These will continue to provide a core for meat production. This 22-part plan is how we can feed the world by 2050. Ideally, where possible, crops should be grown which can be utilised by man and animals. The challenge of producing sufficient food is going to be a massive problem. The daily feed needs to maintain the animal itself and this will be more than the cost of its unit production (milk, eggs, offspring). Intensive research and modeling examining the nexus of the food system, economic development, and the environment show why each of the 22 items on the menu is important and quantifies how far each solution can get us. After land availability and suitable fresh water provision, the ability to reduce, manage and recycle human and animal faecal waste and food waste are major potential limiting factors to food production. Fish are very efficient converters of protein eaten into meat protein. Contrary to our earlier invitation, the programme of the “we’ll 2013” symposium is being reduced to one day: Wednesday 15th May. Most animals will need to be intensively kept as this reduces land requirements, although some farms will still produce for niche markets. Food and Agricultural Organization (2011) Global Food Losses and Food Waste. It will require increased land use and also increased yields per unit of land. Attitudes to acceptance of some foods will need to change. Co. By 2050 the world’s population will reach 9.1 billion, 34 percent higher than today. By 2050, the global population will reach nearly 10 billion people and global food demand will soar by 56%. In 2050 we may have almost 10 billion people to feed. IF the world is to feed itself in 2050 it will have to meet many challenges, both technical and political. A greater understanding of the disease also known as infectious bovine keratoconjunctivitis and its prevention would be welcomed by both farmers and vets, The British Mastitis Conference 2020 discussed new developments in tackling mastitis, from the value of selective dry cow therapy at quarter level to the impact of automatic milking systems, Goats are more susceptible to endoparasites than sheep and never form an immunity to the parasites, unlike their ovine counterparts, Despite being able to work in the fresh air with space and applied hygiene, there are still dangers and analysing risk is now the norm. Farmers, engineers, scientists, and consumers must work together to share and protect the resources necessary to produce enough food so that everyone has enough to eat. There are already a lot of mouths to feed on planet Earth but these five solutions may allow us to feed a 10 billion strong population by 2050. If this is to be utilised effectively other than for fuel, then animal food production from herbivores will have a positive impact. At present, aquaculture produces about 50 million tonnes annually but the knowledge and expertise is becoming available to increase this with potentially only a limited effect on the natural environment. By 2050, there will be an estimated 10 billion people in the world. This will require suitable crop type with minimal and targeted water and fertiliser. Some possible solutions to assist feeding the world in 2050 - part 3. As our global population continues to rise, some estimates suggest it could reach a whopping 10 billion people by 2050. Disease problems will need to be addressed and welfare will also need to be considered. No part of this site may be reproduced without permission. In 2050 I’ll be dead, but that doesn’t mean feeding the world’s population isn’t my concern today. To Feed the World in 2050, We Need to Discuss Agriculture at UN Climate Change Talks 09/10/2013 04:57 pm ET Updated Nov 10, 2013 The relationship between climate change and agriculture is still an area that needs more emphasis at a global level. Attitudes to different foods may need to change locally in socio-economic, ethnic and national terms. Although not on the diet of many developed countries, the consumption of insects and some other invertebrates is already common. To feed that many people, we will need to produce record quantities of food. Farming has produced problems with pollution and spread of disease to wild fish stock. THE main problems with animal intensification are the volumes of water used and the waste products produced. Renewed investment, capacity building, improved infrastructures and the introduction of modernised, intensive and integrated production technologies are the main factors spurring higher growth in these countries. To conserve land, concentrating population in cities, as is currently happening, will assist as will building upwards and not horizontally. However, despite this, man is designed as an omnivore and it is most unlikely that all will subscribe to a vegetarian diet. Almost all salmon eaten these days in Britain and some other European countries has been farmed. Focusing on innovation, markets, people, and political leadership is necessary to ensure a food supply that can feed the population, Gordon Conway says. Animal production will have to become increasingly efficient and will involve veterinarians undertaking work to ensure this occurs and does not compromise the environment. All plant types (conventional and GM) used need to be suitable for the area and the local environment. Can we produce enough food sustainably? Zero grazing may also be useful. this from a library global food futures feeding the world in 2050 brian gardner this is the first text to present a scholarly balanced approach to the contentious area of food production and supply up to 2050 offering a readable and well informed account which tackles the consider these other ways that food drives the future of the economy and. The report offers a five-course menu of solutions to ensure we can feed 10 billion people by 2050 without increasing emissions, fueling deforestation or exacerbating poverty. The scale of the challenge is epic. This implies significant increases in … Only 3% of the world’s water is fresh and of this only 1% is available as liquid. key part of the solution to feeding the World in 2050: a source of nutrient-dense animal-source foods that can support normal physical and mental development … That’s an increase of 2 to 4 billion from today’s population. Can they do it? Feeding The World in 2050- Biobased Solutions for a Growing Population By: Marina Bowie Posted on:01/31/2019 Updated:02/01/2019. It’ll just take some work. Registration 3568194 VAT No. Already salmonid farming has been successfully undertaken and assisted in reducing the price of salmon and trout. Using the production of wheat in the United Kingdom as an example, the current average yield per hectare is 8.4 tonnes. Increased crop production without increasing the amount of land used is the key to feeding a hungry world. Simplistically, it would appear that if a food animal is used to continually produce a particular product, then the more of that product produced by the individual the less the drain on resources such as feed, etc. Agroecology mimics nature, replacing the external inputs like chemical fertilizer with knowledge of how a combination of plants, trees, and animals can enhance the productivity of land. Production per animal (milk, eggs, offspring) will need to increase and each animal will need to have increased longevity. The authors found regions in the world with water supplies that could support this growth. Solutions to feeding the world in 2050 essay. In the case of the waste products in the animal production stage, it can be assisted by producing better balanced diets including lack of excess nutrients, use of dietary ingredients that can be efficiently utilised by the animal, use of additives to further improve digestive efficiency, and also the reduction of stress and disease. By 2050, nearly 10 billion people will live on the planet. The idea that current food production is enough to feed 10 billion people is … It is agreed among the experts that our planet will be supporting over 9 billion of us by 2050. ... at the Times that showed a range of opinion on what it would take to "feed the world." There are various strategies that will reduce their amounts and their effects including intensification, control of dietary constituents, feeding only sufficient, use of compounds to alter ruminant fermentation and digestion, improving efficient production, ensuring good fertility, reducing stress and disease, reducing culling and increasing longevity. Increasing unit production per annum and high total lifetime production needs to be sought. Feeding the world in 2050 requires a revolution Paul R. Ehrlich , John Harte Proceedings of the National Academy of Sciences Dec 2015, 112 (48) 14743-14744; DOI: 10.1073/pnas.1519841112 This is considered too optimistic by some who believe that climate change will restrict future yield growth. Some species are being heavily affected by climate change such as cod, which requires cold water for breeding and is moving north. Desalination was previously mentioned as one method to increase available fresh water: as almost all water is saline it would seem sensible, where possible, to make use of it. It is beyond this article to deal with this but with water it is possible to introduce systems which will improve efficiency of water use and collection, improve irrigation methods and ensure that all water is productively used (every drop counts). Large animal Livestock. Executive Summary – Part 1: How to Feed the World in 2050 e challenge of feeding the world in the year 2050 is fourfold: 1. already in the year 2018, the global food system does not feed its 7.5 billion people properly. 349 7028 73. Those used for meat will need to be grown with maximum feed conversion efficiency. Climatic Change 125 (2): 179-192. ©2021 ‐ Improve International, Alexandra House, Whittingham Drive, Wroughton, Swindon, Wiltshire SN4 0QJ, England. Urbanization will continue at an accelerated pace, and about 70 percent of the world’s population will be urban (compared to 49 percent today). Currently, 40 percent of U.S. corn crop is used for producing ethanol. The growing consensus is that we need to produce 50 to 90 percent more food to feed the expected 9 billion people that will inhabit our earth in 2050. It is suspected, however, that the demand for continuing meat supplies will lead to a compromise over the negative effect of their GHG emissions. The arguments for dairy production from ruminants are easier to make than for meat production when solely looking at GHGs, but continual production of milk at present will mean the production of offspring as well as their eventual culling. It should be possible to provide some of their diet by use of hydroponic production systems. The world’s available land mass will not increase. Focusing on innovation, markets, people, and political leadership is necessary to ensure a food supply that can feed the population, Gordon Conway says. Abel, D. (2014) Farming facts.
