“…Trade may improve balanced nutrition patterns through product diversification while helping to make availability more stable as domestic production uncertainty is higher than the total production risk across international markets (Brooks and Matthews, 2015). International trade is also believed to have an important role in reducing the adverse effects of climate change on food security (Nelson, McCarl and Thayer, 2010;Chen et al, 2017). The observations conducted by FAO (2005) also confirm the existence of a positive relationship between market openness and food security.…”

The main purpose of this paper was to assess the openness of trade in food products in the context of changes in food security levels. The period covered by this study is 1995-2015. The research was based on outcomes reported by main players of the global market. The basic source of data were online databases and reports. Once collected, the data was analysed with the use of quantitative and qualitative research methods. Selected statistical methods, indices of structure and dynamics, indicators of economic openness and indicators related to three dimensions of security (availability, access and stability) were used. The analysis resulted in numerous conclusions. In the study period, food imports followed a global growth trend with alternating periods of contrasting developments. In the countries covered by this study, the openness of trade in food was higher than that of global imports and followed a growth trend. The singularities of the development of the agri-food sector were reflected in decreasing values of the exports-to-imports ratio, and were decisive for the positive growth rate of per capita agri-food output. According to the analysis of relationships between changes in trade levels and selected food security indicators, imports proved to be positively correlated with physical and economic availability, and negatively correlated with stability. Based on the results, a general conclusion may be drawn that economic growth resulted in structural changes which contributed to improving access to food.

“…This supports the outcomes of Kabubo-Mariara and Kabara (2015), who found that global warming would lead to a rise in food scarcity. Chen et al (2017) explored how threats, change, and food safety are affected by global warming. It was determined that the effects of global warming on the agriculture sector will vary globally, with some systems benefiting and many others suffering.…”

The research investigated the idea of clean energy and how it affects food security utilizing panel data from selected African nations. The World Development Indicators (WDI) for the years 2005 to 2022, the Food and Agricultural Organization (FAO), and the Country Policy and Institutional Assessment (CPIA) were the sources of data. The study engaged the generalized method of moments (GMM), and the results showed that clean energy indicators have both beneficial and adverse effects on food security. This is crucial for policy toward the actualization of sustainable development goals of no poverty (SDG1), no hunger (SDG2), clean and affordable energy (SDG7), sustainable cities (SDG11), and climate action (SDG13). The findings of this study will benefit policymakers, governments, and organizations working toward promoting clean energy, sustainable agriculture, and food security in Africa. It will also benefit farmers and communities who rely on agriculture for their livelihoods. By implementing the recommendations of the study, these stakeholders can work toward a more sustainable and secure future for Africa. Additionally, the environment and global efforts to mitigate climate change will also benefit from the reduction in greenhouse gas emissions.

“…Cropland is assigned higher priority based on our view that food security will continue to be a priority given the growing population (J. Chen et al, 2017;Gregory et al, 2005;Vermeulen et al, 2012). Note that in the original BNU dataset, urban area can shrink at certain future time points as the projected urban population decreases.…”

Urbanization (urban land change) alters local and regional climate through biophysical and biogeochemical processes and has broader climate impacts through atmospheric feedbacks. Despite its critical climate impacts, urban areas have rarely been explicitly represented in global-scale Earth system models, and physically-based transient urban representations are missing as well. The Community Earth System Model (CESM) has a physically based urban land parameterization – Community Land Model Urban (CLMU) – that is sufficiently detailed to represent the properties and processes in the urban environment. We improve this model by implementing a dynamic urban scheme to represent transient land use due to urbanization. Leveraging existing urbanization projection datasets, the new scheme allows urban extent to be updated annually during a climate simulation while conserving energy and mass balance during the transition. Land-only simulation results confirm the robustness of the new dynamic urban scheme and demonstrate the direct local climate effects induced by urban land expansion. In the appendix of this paper, we also document two recent improvements to the building energy scheme of CLMU.
