Nigeria’s efforts to attain food security has been tipped to reach substantial levels before the next decade, the prediction was contained in recent data from the Food and Agriculture Organization (FAO) in partnership with Gallup World Poll, the World Data Lab.
According to the report, the number of food insecurity will continue to rise in sub-Saharan Africa, while economic development will also continue rapidly and in many parts of Africa, population growth will outpace the improvements in food security.
The report stated that many lower-middle-income African countries will make large strides in decreasing the rate of food security, particularly Nigeria, Senegal, Ghana, Kenya, and Ethiopia, but in absolute numbers, food insecurity will continue to increase throughout the continent.
Food insecurity has been increasing in recent years, and has been further exacerbated in 2020 by the coronavirus. The World Data Lab has used machine learning techniques and the latest forecasts of global change to estimate the dynamics of food insecurity for the coming decade.
This forecast is displayed at subnational spatial resolution on the World Hunger Clock, allowing policymakers to explore the data and answer important questions about hunger.
Scientists have been studying food security for decades, and for many years, they relied on crude metrics, such as food available per capita, or the rate of stunting among children. However, these methods come with a variety of problems. Looking at the amount of food stored in national reserves does not account for inequalities in access to that food, while population level metrics like rates of stunting are confounded by things like infectious disease and parasites.
Today, scientists use a new metric called the Food Insecurity Experience Scale, which measures people’s lived experiences of hunger, rather than just crude proxies for hunger. It involves questions about skipping meals, running out of food, and worrying about having enough to eat over the previous year. As one of the most informative and cross-culturally valid metrics of food insecurity, it was selected as one of the key indicators for the second Sustainable Development Goal of Zero Hunger. Now, with the World Hunger Clock, it is possible to explore this important metric at high spatial resolution including projections into the future for the entire world.
To map world hunger, we trained a machine learning model with the best data available today on variables like wealth, education, demographics, urbanization, and the climate. The model was able to predict recent historic rates of food insecurity with very high accuracy. Then, based on how those variables are likely to change in the coming years, estimated rates of food insecurity in the future.
The model was also used to predict both moderate food insecurity—eating less than you would like, as well as severe food insecurity—going an entire day without eating.
In recent years, the model confirms that both moderate and severe food insecurity have been on the rise in terms of absolute numbers. Due to the impact of the coronavirus on the global food system, 2020 and 2021 will see the highest levels of hunger in over a decade. Today, nearly 2.5 billion people—almost one-third of the world’s population—have some level of hunger, due to lacking the resources to purchase the food they would like, while 800,000 people are severely food insecure, going entire days without eating at least once.
Where things are getting worse and where they are getting better
Breaking down the model’s predictions by world region shows a dynamic picture. East Asia has been continuing a pattern of increasing development and access to food, so the number of food insecure people has decreased and will continue to do so. Not only are people leaving a state of food insecurity and poverty, but people are achieving a middle-class lifestyle. Increasingly, the challenge people and policymakers face in this region is not the challenge of eating enough but rather eating well—having diets that do not lead to obesity and that do not have an excessive impact on the environment.
Finally, South Asia is predicted to turn a corner on food insecurity. Having seen the number of hungry people increase throughout the last decade, the number of both moderate and severely food insecure people will begin to decrease in the early 2020s. This is due to a combination of economic growth bringing people out of poverty as well as the fruits of long-term trends in reduced stunting and malnutrition.
As the recent well-deserved Nobel Peace Price received by the World Food Programme shows, ensuring that all people on earth have access to safe, nutritious, and sufficient food is an important goal to strive for, and many organizations are currently paying attention to global hunger. The novel World Hunger Clock will contribute to global efforts to achieve this goal and help policymakers to better understand where hunger still exists and how it is changing.
