The main aim of the paper was an analysis of the present status and changes of commercially grown genetically modified crops and food security from 2012 to 2018, based on the Global Food Security Index by countries. The work used a descriptive approach with elements of inductive reasoning and meta-analysis based on secondary data, derived from Briefs of The International Service for the Acquisition of Agri-biotech Applications, FAOSTAT and the GFSI, developed and calculated by The Economist Intelligence Unit. The study showed the highest increase in biotech crops was observed in Brazil and the USA, i.e. in countries with a relatively high level of GFSI. Accordingly, the highest positive change in GFSI was achieved in several countries both with quite a high level of GFSI (Chile, Uruguay and Argentina) and with a very low GFSI (Burkina Faso and Myanmar). A slightly positive Pearson correlation coefficient for the area of biotech crops and GFSI indicated that, in the analysed period, when an increase in GM crop area was observed, the value of the GFSI increased as well. However, the value of the Pearson correlation means that the biotech crop area can be considered one of the many factors influencing the food security of the studied countries. The results show that biotech crops cannot only be analysed in the context of food security at a country level, but also at a household level. GM crops could contribute to food production increases and higher food availability, however not necessarily to food security, especially at a country level.

Abstract Ending hunger and achieving food security - one of the UN sustainable development goals - is a major global challenge. To inform the policy debate, quantified global scenarios and projections are used to assess long-term future global food security under a range of socio-economic and climate change scenarios. However, due to differences in model design and scenario assumptions, there is uncertainty about the range of food security projections and outcomes. We conducted a systematic literature review and meta-analysis to assess the range of future global food security projections to 2050. We reviewed 57 global food security projection and quantitative scenario studies that have been published over the last two decades and discussed the methodology, underlying drivers, indicators and projections. We harvested quantitative information from 26 studies to compare future trends of the two most used global food security indicators: per capita food demand (593 projections) and population at risk of hunger (358 projections). We found that across five representative scenarios that span divergent but plausible socio-economic futures total global food demand is expected to increase by +35% to +56% between 2010 and 2050, while population at risk of hunger is expected to change by -91% to +8% over the same period. If climate change is taken into account the range changes slightly (+30% to +62% for total food demand and -91% to +30% for population at risk of hunger) but overall we do not find statistical support for differences in projections with and without climate change. Finally, our review suggests that current modeling approaches can be improved by better incorporating several options that have been proposed to tackle global food security, in particular aquaculture and ‘future foods’, and expand the number of indicators to better cover the multiple dimensions of food security. The results of our review can be used to benchmark new global food security projections and quantitative scenario studies and inform policy analysis and the public debate on the future of food.

The authors assess the prospects for solving the global food problem based on an analysis of the dynamics of food security indicators at the global and regional levels. The global food problem at work refers to the growing population of a planet affected by hunger and other forms of malnutrition. The food security situation has worsened for five years - in 2015–2019, and the COVID-19 pandemic has further exacerbated the food supply problem. The prevalence of moderate to severe food insecurity has affected more than 25% of the world's population. In lowincome countries, malnutrition affects more than 58% of the population. Food security is threatened by the consequences of the spread of coronavirus infection in the short term. In the medium and long term, climate change and the crisis in the governance of the world economy are the greatest threats. Modern international economic institutions are unable to withstand the prospect of declining global food security.

Starting in 2008 and lasting up until 2011, the crisis in agricultural and, in particular, cereal prices triggered a period of riots that spread from the Mediterranean basin to the rest of the world, reaching from Asia to Central America and the African continent. [...]
