This study examined the situation of food insecurity in Africa with special emphasis on Nigeria with a view to giving the picture of the trend with respect to causes, effects and possible solutions. The study employed secondary data sourced from the Food and Agricultural Organization (FAO) of the United Nations and subsequently compared the results with other previously conducted studies on food security status in Nigeria and few other African countries. Data for the trend of food security between 1990 and 2014 were sourced from FAO. The findings of this study combined with other previously conducted studies revealed that the food insecurity in Nigeria is not only becoming worrisome but frightening. According to the FAO three commonly employed indicators (prevalence of undernourishment, prevalence of food insecurity and number of undernourished people), it was observed that food insecurity in Nigeria continued to rise from 2009 according to the results of the annual survey till 2014. The implication of this is that if the trend is not halted as quickly as possible it is a time bomb that may pose grave security risks and danger to the country and Africa as a whole being the most populous black nation and it is almost certain that any destabilization suffered as a result of hunger in Nigeria is a destabilization of the entire sub-Saharan Africa region considering her enormous population and the strategic place she occupies in the economy of the region especially the western Africa. This paper made some far-reaching recommendations that could halt the trend if judiciously implemented.


Significance These developments threaten to ignite a multi-dimensional civil war pitting Tigrayan against federal and Amhara regional forces. Impacts The conflict will test the cohesion of the military, which was once dominated by Tigrayans but has been undergoing reforms under Abiy. Abiy is likely to view international intervention as a sign of loss of control and may reject mediation offers. Amhara forces may try to reclaim ‘historic’ Amhara areas that Tigray allegedly arrogated, potentially displacing many Tigrayans. Alongside desert locust swarms in parts of the country, including Tigray, the conflict may worsen food security risks. Elections tentatively rescheduled for May or June 2021 may be postponed again.

The stability of food supply chains is crucial to the food security of people around the world. Since the beginning of 2020, this stability has been undergoing one of the most vigorous pressure tests ever due to the COVID-19 outbreak. From a mere health issue, the pandemic has turned into an economic threat to food security globally in the forms of lockdowns, economic decline, food trade restrictions, and rising food inflation. It is safe to assume that the novel health crisis has badly struck the least developed and developing economies, where people are particularly vulnerable to hunger and malnutrition. However, due to the recency of the COVID-19 problem, the impacts of macroeconomic fluctuations on food insecurity have remained scantily explored. In this study, the authors attempted to bridge this gap by revealing interactions between the food security status of people and the dynamics of COVID-19 cases, food trade, food inflation, and currency volatilities. The study was performed in the cases of 45 developing economies distributed to three groups by the level of income. The consecutive application of the autoregressive distributed lag method, Yamamoto’s causality test, and variance decomposition analysis allowed the authors to find the food insecurity effects of COVID-19 to be more perceptible in upper-middle-income economies than in the least developed countries. In the latter, food security risks attributed to the emergence of the health crisis were mainly related to economic access to adequate food supply (food inflation), whereas in higher-income developing economies, availability-sided food security risks (food trade restrictions and currency depreciation) were more prevalent. The approach presented in this paper contributes to the establishment of a methodology framework that may equip decision-makers with up-to-date estimations of health crisis effects on economic parameters of food availability and access to staples in food-insecure communities.

AbstractGlobal biodiversity is projected to further decline under a wide range of future socio-economic development pathways, even in sustainability oriented scenarios. This raises the question how biodiversity can be put on a path to recovery, the core challenge for the CBD post-2020 global biodiversity framework. We designed two contrasting, ambitious global conservation strategies, ‘Half Earth’ (HE) and ‘Sharing the Planet’ (SP), and evaluated their ability to restore terrestrial and freshwater biodiversity and to provide ecosystem services while also mitigating climate change and ensuring food security. We applied the integrated assessment framework IMAGE with the GLOBIO biodiversity model, using the ‘Middle of the Road’ Shared Socio-economic Pathway (SSP2) with its projected human population growth as baseline.We found that both conservation strategies result in a reduction in the loss of biodiversity and ecosystem services globally, but without additional measures to achieve effective climate mitigation they will be insufficient to restore biodiversity. The HE strategy performs better for terrestrial biodiversity protection (biodiversity intactness (MSA), Red List Index, geometric mean abundance) in currently still natural regions, reflecting global conservation priorities. The SP strategy yields more improvements for biodiversity in human-used areas, aquatic biodiversity and for regulating ecosystem services (pest control, pollination, erosion control), reflecting regional priorities. However, ‘conservation only’ scenarios show a considerable increase in food security risks (especially in Sub-Saharan Africa) compared to the baseline and limited reduction of global temperature increase. Only when conservation strategies are combined with climate change mitigation efforts and additional actions especially in the agricultural and energy system into a portfolio of ‘integrated sustainability measures’, both conservation strategies result in restoring biodiversity to current values or even some improvement, while keeping global warming below two degrees and keeping food security risks below baseline. Minimizing food wastes and reducing consumption of animal products will be crucial.

(1) Background: COVID-19 has exacerbated global food security risks, and the global food supply chain, especially in developing countries, has become more vulnerable. (2) Methods: In this paper, we discussed the current security of global food, response measures, and potential impacts, and analyzed the characteristics and evolution of food security policies in four representative countries: China, Italy, Malawi, Argentina. (3) Results: The results showed that most countries give priority to ensuring food access. Most underdeveloped countries adopt humanitarian intervention measures such as food distribution and transfer payments, while developed countries tend to implement development intervention policies such as supporting small- and medium-sized enterprises and guaranteeing employment. (4) Conclusions: Despite the ample global supply, developing countries still face long-term food security risks, highlighting the importance of strengthening global food security governance and risk management. Finally, a food security risk response policy framework was built to provide suggestions for effectively handling COVID-19 and similar public health emergencies in the future.
