Urbanization and food insecurity risks: assessing the role of human development

The phenomenon of rapid urbanisation across the world has become a topic of increased scholarly inquiry. Yet, little attention has been paid to how urban growth affects countries’ food security and whether this association is modified by a country's level of development. The present study aims to fill this lacuna by examining the association between urbanisation and food security applying statistical modelling. The analysis uses country-level data, from the World Development Indicators and the United Nations’ World Urbanization Prospects. Using a Food Insecurity Risk Index (FIRI) as the outcome variable, the results confirm a significant negative impact of urban growth on food security at the country level. It further finds that rapidly urbanising countries with the lowest levels of human development are most at risk of food insecurity

Is it time to reconceptualise global food insecurity?

LSE alumna Sylvia Szabo argues that food insecurity is a global issue, not one just facing developing countries

Inequalities in Human Well-Being in the Urban Ganges Brahmaputra Meghna Delta

The recently endorsed Sustainable Development Goals (SDGs) agenda unanimously agrees on the need to focus on inclusive development, the importance of eradicating extreme poverty and managing often complex human well-being impacts of rapid urban growth. Sustainable and inclusive urbanisation will accelerate progress towards the SDGs and contribute to eradicating extreme poverty. In tropical delta regions, such as the Ganges Brahmaputra Meghna delta region, urban growth and resulting intra-urban inequalities are accelerated by the impact of environmental and climate change. In this context, the present study uses the 2010 Household Income and Expenditure Survey to analyse the extent of wealth-based inequalities in human well-being in the urban delta region and the determinants of selected welfare measures. The results suggest that the extent of intra-urban inequalities is greatest in educational attainment and access to postnatal healthcare and relatively low in the occurrence of gastric disease. The paper concludes by providing policy recommendations to reduce increasing wealth inequalities in urban areas, thus contributing to sustainable development of the region

Perception of the probability of Korean unification amongst South Korea’s elderly population

While Korean unification remains one of the most significant issues in inter-Korean and international affairs, little is known about the perception of the likelihood of the Korean unification, especially amongst the elderly population. Yes, the proportion of the population in South Korea has been rapidly rising, becoming an increasingly important civic group. In this study, we analyzed the data from the 2018 nationally representative Korean Longitudinal Study of Aging survey using ordered logistic regression modelling. The results show that age, life satisfaction, health status, participation in social activities, and geographical location are the most important factors affecting the perception of Korean unification. We also find some gender differences in relation to the impact of education and wealth. Further qualitative studies might be useful to gain an in-depth understanding of people’s perceptions as well as possible socioeconomic and cultural barriers to a potential pre-unifying process

Impacts of COVID-19 Non-pharmaceutical Interventions on Trade Flows: A Global Panel Vector Autoregression Analysis

The COVID-19 outbreak has contributed to a tremendous global decline in international trade flows. The rapid spread of the disease and the control measures implemented by governments to contain the virus have led to serious consequences for the global economy. The pandemic has affected the international movement of people, goods, and services. Currently, the systematic quantitative research investigating the effects of specific non-pharmaceutical intervention policy clusters on country-level international trade flows, remains limited. In this study, the Panel Vector Autoregression (PVAR) method was conducted using country-level panel data collected from various international sources including the United Nations, World Bank, and University of Oxford. The results show that stringent COVID-19 closure, social distancing, and containment measures and health-related measures, had significant negative impacts on trade flows. In contrast, economic support measures showed significant positive effects on trade. In summary, the findings suggest that policymakers should maintain less stringent containment measures related to public closure and movement restrictions and stimulate economic activities through economic support policies in order to minimize losses in trade flows during the pandemic

Population dynamics, delta vulnerability and environmental change: comparison of the Mekong, Ganges–Brahmaputra and Amazon delta regions

Tropical delta regions are at risk of multiple threats including relative sea level rise and human alterations, making them more and more vulnerable to extreme floods, storms, surges, salinity intrusion, and other hazards which could also increase in magnitude and frequency with a changing climate. Given the environmental vulnerability of tropical deltas, understanding the interlinkages between population dynamics and environmental change in these regions is crucial for ensuring efficient policy planning and progress toward social and ecological sustainability. Here, we provide an overview of population trends and dynamics in the Ganges–Brahmaputra, Mekong and Amazon deltas. Using multiple data sources, including census data and Demographic and Health Surveys, a discussion regarding the components of population change is undertaken in the context of environmental factors affecting the demographic landscape of the three delta regions. We find that the demographic trends in all cases are broadly reflective of national trends, although important differences exist within and across the study areas. Moreover, all three delta regions have been experiencing shifts in population structures resulting in aging populations, the latter being most rapid in the Mekong delta. The environmental impacts on the different components of population change are important, and more extensive research is required to effectively quantify the underlying relationships. The paper concludes by discussing selected policy implications in the context of sustainable development of delta regions and beyond

Making SDGs work for climate change hotspots

The impacts of climate change on people's livelihoods have been widely documented. It is expected that climate and environmental change will hamper poverty reduction, or even exacerbate poverty in some or all of its dimensions. Changes in the biophysical environment, such as droughts, flooding, water quantity and quality, and degrading ecosystems, are expected to affect opportunities for people to generate income. These changes, combined with a deficiency in coping strategies and innovation to adapt to particular climate change threats, are in turn likely to lead to increased economic and social vulnerability of households and communities, especially amongst the poorest

Accelerating progress towards the Zero Hunger Goal in cross-boundary climate change hotspots

The most recent 2017 United Nations’ Sustainable Development Goals progress report highlighted the need to accelerate the pace of progress in order for the Sustainable Development Goals to be fully achieved. Responding to these concerns, the present commen tary proposes four distinct, but interrelated approaches to accelerate the Zero Hunger G oal in transboundary climate change hotspots, regions which suffer from multiple stressors and vulnerabilities, and in which prevalence of food insecurity and malnutrition often remains disproportionately high. These conceptual, programmatic and policy approaches are discussed drawing from a newly developed conceptual framework and referring to specific examples from climate change hotspots around the world
