This paper explores evidence relevant to the hypothesis that human-generated climate change (global warming) is already, and will increasingly, add to the existing burden of disadvantage experienced by populations in low-income countries, the ‘Global South'. Well recognised health manifestations of global warming include from heatwaves and other extreme weather events, changes to infectious disease patterns, and undernutrition, arising from higher food prices, reduced food availability and reduced nutrient concentrations of many foods. These effects have been called ‘primary' and ‘secondary'. Although these manifestations will have effects globally, their biggest impact on health is and will be upon poor and vulnerable populations in low-income settings. Also well recognised, manual labourers are increasingly vulnerable from excessive heat and humidity. There is less recognition that climate change interacts with social and political determinants of health, contributing to ‘tertiary' health consequences including conflict, forced migration and famine. In turn, these effects may deepen poverty traps in the Global South. Human-generated climate change is principally caused by the policies and lifestyles of populations in high-income countries (the Global North). The recent recognition by the British government that climate change is an emergency is encouraging, and may help motivate the widespread global behavioural changes that are needed to reduce the many risks from global warming, including to the people of the South.

Climate change will continue to have a largely detrimental impact on the agricultural sector worldwide because of predicted rising temperatures, variable rainfall, and an increase in extreme weather events. Reduced crop yields will lead to higher food prices and increased hardship for low income populations, especially in urban areas. Action on climate change is one of the Sustainable Development Goals (SDG 13) and is linked to the Paris Climate Agreement. The research challenge posed by climate change is so complex that a trans-disciplinary response is required, one that brings together researchers, practitioners, and policy-makers in networks where the lines between “research” and “development” become deliberately blurred. Fostering such networks will require researchers, throughout the world, not only to work across disciplines but also to pursue new South–North and South–South partnerships incorporating policy-makers and practitioners. We use our diverse research experiences to describe the emergence of such networks, such as the Direct Seeded Rice Consortium (DSRC) in South and Southeast Asia, and to identify lessons on how to facilitate and strengthen the development of trans-disciplinary responses to climate change.

Abstract The impacts of climatic disasters have been rising globally. Several studies argue that this upward trend is due to rapid growth in the population and wealth exposed to disasters. Others argue that rising extreme weather events due to anthropogenic climate change are responsible for the increase. Hence, the causes of the increase in disaster impacts remain elusive. Disaster impacts are higher in low-income countries, but existing studies are mostly from developed countries or at the cross-country level. Here we assess the spatiotemporal trends of climatic disaster impacts and vulnerability and their attribution to climatic and socioeconomic factors at the subnational scale in a low-income country, using Nepal as a case study. Loss of life is the most extreme consequence of disasters. Therefore, we employed human mortality as a measure of disaster impacts, and mortality normalized by exposed population as a measure of human vulnerability. We found that climatic disaster frequency and mortality increased in Nepal from 1991 to 2020. However, vulnerability decreased, most likely due to economic growth and progress in disaster risk reduction and climate change adaptation. Disaster mortality is positively correlated with disaster frequency and negatively correlated with per capita income but is not correlated with exposed population. Hence, population growth may not have caused the rise in disaster mortality in Nepal. The strong rise in disaster incidence, potentially due to climate change, has overcome the effect of decreasing vulnerability and caused the rise in disaster mortality.

Background Climate change, including global warming, will cause poorer global health and rising numbers of environmental refugees. As neurological disorders account for a major share of morbidity and mortality worldwide, global warming is also destined to alter neurological practice; however, to what extent and by which mechanisms is unknown. We aimed to collect information about the effects of ambient temperatures and human migration on the epidemiology and clinical manifestations of neurological disorders. Methods We searched PubMed and Scopus from 01/2000 to 12/2020 for human studies addressing the influence of ambient temperatures and human migration on Alzheimer’s and non-Alzheimer’s dementia, epilepsy, headache/migraine, multiple sclerosis, Parkinson’s disease, stroke, and tick-borne encephalitis (a model disease for neuroinfections). The protocol was pre-registered with PROSPERO (2020 CRD42020147543). Results Ninety-three studies met inclusion criteria, 84 of which reported on ambient temperatures and nine on migration. Overall, most temperature studies suggested a relationship between increasing temperatures and higher mortality and/or morbidity, whereas results were more ambiguous for migration studies. However, we were unable to identify a single adequately designed study addressing how global warming and human migration will change neurological practice. Still, extracted data indicated multiple ways by which these aspects might alter neurological morbidity and mortality soon. Conclusion Significant heterogeneity exists across studies with respect to methodology, outcome measures, confounders and study design, including lack of data from low-income countries, but the evidence so far suggests that climate change will affect the practice of all major neurological disorders in the near future. Adequately designed studies to address this issue are urgently needed, requiring concerted efforts from the entire neurological community.

How people subjectively perceive climate change strongly influences how they respond to its challenges. To date, relatively little is known about such perceptions in the Global South. This research examines public perceptions of climate change in the Peruvian Andes, a semi-arid high-mountain region that is highly exposed and vulnerable to adverse effects of climate change. Based on questionnaire data collected through face-to-face interviews (N = 1316), we found that respondents identify various climate-related issues as the most important challenges for their country. Many of these issues are related to water. Respondents also noticed more subtle changes and expected them to continue (e.g., extreme temperatures, food shortages). Climate impacts were clearly seen as negative, which was also reflected in the presence of emotions. When compared to previous research, more respondents had personally experienced extreme weather events (80%) and they were more certain that the climate is already changing, is caused by human activity, and is affecting distant and close places similarly. A comparison of the perceptions along different socioeconomic characteristics suggests that more vulnerable groups (e.g., rural, low income and education levels) tended to perceive climate change as more consequential, closer, and as a more natural (vs. anthropogenic) phenomenon than those from less vulnerable groups. The salience of water-related problems and personal experiences of climate-related events, as well as differences between various subgroups, could be used to improve measures to adapt to the consequences of climate change by correcting misconceptions of the population and of decisionmakers.

Climate change is posing a threat on present and future food security in low income countries. But, the actual effect of the climate change on food security is not known. Using secondary data reported by the government, the paper examines the effects of climate change on food security in Nepal in the context of policies of commercialization of farm production. Statistical analysis is used to delineate the situation of food security in the country and regression analysis for exploring the effects of global warming on domestic production of major cereals. The results are discussed at global, national, household and individual levels empirically and qualitatively. The results suggest that a rise in minimum temperature decreases the productivity of rice increasing threat of food insecurity. The paper suggests some policy measures for improving food security situation in the country and open up some areas for further research.

The impacts of human-induced climate change are manifested through losses and damages incurred due to the increasing frequency and intensity of climatic disasters all over the world. Low-income countries who have contributed the least in causing climate change, and have low financial capability, are the worst victims of this. However, since the inception of the international climate regime under the UN Framework Convention on Climate Change (UNFCCC), loss and damage has been a politically charged issue. It took about two decades of pushing by the vulnerable developing countries for the agenda to formally anchor in the climate negotiations text. This was further solidified through establishment of the Warsaw International Mechanism (WIM) and inclusion of stand-alone Article 8 on loss and damage in the Paris Agreement. Its institutionalisation has only done the groundwork of addressing loss and damage however - the key issue of finance for loss and damage and other matters has remained largely unresolved to date – particularly since Article 8 does not have any provision for finance. This has been due to the climate change-causing wealthy developed nations' utter disregard for their formal obligations in the climate regime as well as their moral obligation. In this article, we tease out the central controversies that underpin the intractability of this agenda at the negotiations of the UNFCCC. We begin by giving a walk-through of the concept and history of loss and damage in the climate regime. Then we present a brief account of losses and damages occurring in the face of rising temperature, and highlight the key issues of contention, focusing on the more recent developments. Finally, we conclude by suggesting some way forward for the twenty-sixth session of the Conference of the Parties to the UNFCCC (COP26) taking place in Glasgow, UK in November 2021.

Climate change is threatening future global food and nutrition security. Limiting the increase in global temperature to 1·5 °C set out in The Paris Agreement (2015) while achieving nutrient security means overhauling the current food system to create one that can deliver healthy and sustainable diets. To attain this, it is critical to understand the implications for nutrition of actions to mitigate climate change as well as the impacts of climate change on food production and the nutrient composition of foods. It is widely recognised that livestock production has a much greater environmental burden than crop production, and therefore advice is to reduce meat consumption. This has triggered concern in some sectors about a lack of protein in diets, which hence is driving efforts to find protein replacements. However, in most high- and middle-income countries, protein intakes far exceed dietary requirements and it would even if all meat were removed from diets. Reduction in micronutrients should be given more attention when reducing meat. Simply eating less meat does not guarantee healthier or more sustainable diets. Climate change will also affect the type, amount and nutrient quality of food that can be produced. Studies have shown that increased temperature and elevated CO2 levels can reduce the nutrient density of some staple crops, which is of particular concern in low-income countries. Nutrition from a climate change perspective means considering the potential consequences of any climate action on food and nutrition security. In this paper, we discuss these issues from an interdisciplinary perspective.
