Current evidence that the climate is changing is overwhelming. Impacts of climate change and variability are being observed: more intense heat-waves, fires and floods; and increased prevalence of food- water- and vector-borne diseases. Climate change will put pressure on environmental and health det...erminants, such as food safety, air pollution and water quantity and quality. A climate-resilient future depends fundamentally on reducing greenhouse gas emissions. Limiting warming to below 2 °C requires transformational technological, institutional, political and behavioural changes: the foundations for this are laid out in the Paris Agreement of December 2015. The health sector can lead by example, shifting to environmentally friendly practices and minimizing its carbon emissions. A climate-resilient future will increasingly depend on managing and reducing climate change risks to protect health. In the near term, this can be enhanced by including climate change in national health programming and creating climate-resilient health systems.

Clean and sustainable household energy and appliances, for cooking, heating and lighting can improve health, increase productivity, reduce poverty and protect the environment while addressing air pollution.
The Lancet Global Health Volume 9, ISSUE 3, e361-e365, March 01, 2021
The public health community has tried for decades to show, through evidence-based research, that safe water, sanitation, and hygiene (WASH) and clean cooking fuels that reduce household air pollution are essential to safeguard he...alth and save lives in low-income and middle-income countries. In the past 40 decades, there have been many innovations in the development of low-cost and efficacious technologies for WASH and household air pollution, but many of these technologies have been associated with disappointing health outcomes, often because low-income households have either not adopted, or inconsistently adopted, these technologies.

The following technical report outlines the rationale, process and results of a joint research study, coordinated by the World Health Organization (WHO) and the Pan-American Health Organization (PAHO), co-chaired by the Ministry of Health and Social Protection and the Ministry of Environment and Sus...tainable Development in collaboration with the Climate and Climate Air Coalition, the Stockholm Environment Institute, the Clean Air Institute and leading international and national experts. A rationale section describes the links between greenhouse gas (GHG) emissions, short-lived climate pollutants, air pollution and adverse health outcomes. A summary of the research study describes how scenarios were modelled to examine the health and economic implications of raising ambition in Colombia’s Nationally Determined Contribution (NDC) to the United Nations Framework Convention on Climate Change (UNFCCC)

In 2019, WHO estimated that 6.7 million premature deaths could be attributed to ambient and household air pollution from particulate matter (particles with a diameter less than 2.5 μm, PM2.5. Of the 4.2 million deaths attributed specifically to ambient air pollution exposures.
Human health and well-being are intimately linked to the state of the environment. Water, sanitation and hygiene (WASH), climate change, air pollution and exposure to hazardous chemicals are major causes of environment-related burden of disease across the world. In the WHO South-East Asia Region, al...most a quarter of all deaths are attributable to the health impacts of environmental hazards. Air pollution is the leading cause of deaths from environmental risks and is a leading contributor to the NCD epidemic.

The article "Asthma in South African adolescents: a time trend and risk factor analysis over two decades" investigates the prevalence and risk factors for asthma in Cape Town adolescents from 2002 to 2017. The study finds that while the overall prevalence of asthma remained similar, the severity of ...the condition increased significantly. Risk factors for asthma and severe cases include smoking, pet exposure, outdoor pollution, and living in informal housing. Despite these trends, underdiagnosis remains a concern, as only one-third of adolescents with current or severe asthma had been formally diagnosed. The article emphasizes the need for better public health strategies to address environmental exposures and improve asthma diagnosis and treatment.

The article analyzes the prevalence and risk factors of chronic respiratory diseases, focusing on sub-Saharan Africa. It highlights that environmental exposures, such as biomass fuel usage and air pollution, significantly contribute to respiratory health issues in the region. The research underlines... the limited healthcare infrastructure, insufficient diagnostic tools, and the need for comprehensive data collection to better understand the burden of respiratory diseases. The authors advocate for targeted public health interventions, improved access to healthcare, and policies aimed at reducing exposure to risk factors to mitigate the prevalence of respiratory conditions.

Oxfam Water Supply Scheme for Emergencies. This manual is part of a series of guides devised by the Oxfam Public Health Engineering Team to help provide a reliable water supply for populations affected by conflict or natural disaster. Wherever possible, water supplies in emergency conditions should ...be obtained from underground sources by exploitation of springs, tubewells, or dug wells. No filtration will then be needed. However, if sources are not available or cannot be developed, the use of surface water from streams, rivers, lakes or ponds becomes necessary. Usually these surface sources are polluted. The level of faecal contamination can be measured by use of the Oxfam/Delagua Water Test Kit (see Section C). Where a serious level of faecal pollution exists, it is essential firstly to try to reduce the cause of contamination, and secondly to treat the water to make it suitable for human consumption. The Filtration equipment provides a simple, long-term physical and biological treatment system that requires no chemicals (except small amounts of chlorine required during filter cleaning) and needs only simple regular maintenance

Over half a billion children are living in areas with extremely high levels of floods and nearly 160 million children live in areas of high or extremely high droughts. The World Health Organisation (WHO) estimates that 26% of the annual 6.6 million deaths of children under five are linked to environ...ment-related causes and conditions. Children are also disproportionately affected by pollution, not only in terms of death rates, but also in terms of cognitive and physical development. This report illustrates that environmental causes also have an impact on whether children are pushed to work and on the kind of work they engage in, the conditions of work, exposure to dangerous toxicants and the risk of exploitation. However, the report raises more questions than it answers as it is one of the first reports addressing the question, how environmental degradation and climate change affect the vulnerability of children towards exploitation.

Au Burkina Faso, les personnes vivant avec le VIH (PvVIH) ont régulièrement recours à des substances naturelles pour traiter certaines infections opportunistes. C’est ainsi que le suc des feuilles fraîches de Mitracarpus scaber Zucc. ex Schult. & Schult. f. (Rubiaceae) et de Senna alata (L.) R...oxb. (Fabaceae) sont utilisés comme antimycosiques. En ce qui concerne le zona et les poussées herpétiques, les feuilles fraîches de Phyllanthus amarus Schumach. & Thonn. (Euphorbiaceae), la sève de Mangifera indica L. (Anacardiaceae), le gel de Aloe buettneri Berger (Liliaceae) et la galle de Guiera senegalensis J.F. Gmel. (Combretaceae), sont les drogues végétales les plus utilisées. Des substances naturelles sont également recommandées par les tradipraticiens de santé pour la récupération immunologique et nutritionnelle, le traitement précoce de l’infection à VIH et la réduction des effets secondaires des traitements ARV (antirétroviral). Il s’agit respectivement pour les plus importantes d’entre elles, des feuilles de Moringa oleifera Lam. (Moringaceae), de la pulpe du fruit de Detarium microcarpum Guill. & Perr. (Fabaceae), de la spiruline et du pollen issu de la ruche.
Les substances naturelles pouvant avoir une interaction avec les traitements conventionnels et plus particulièrement avec les médicaments ARV, les plantes contenant des tanins catéchiques, des dérivés 1,8 hydroxyanthracéniques laxatifs et des molécules hépatotropes ou inductrices enzymatiques, sont classées à risque, et leur utilisation par les PvVIH est étroitement surveillée.

China is one of the major countries for the production and use of antibacterial agents. Antibacterial agents are widely used in healthcare and animal husbandry. It plays a significant role in treating infections and saving patient lives, preventing and treating animal diseases, improving farming ef...ficiency, and guaranteeing public health security. However, antimicrobial resistance has become increasingly prominent due to insufficient research and development capacity of new antimicrobials, sales of antimicrobials without prescriptions in pharmacies, irrational use of antibacterial agents in medical and food animal sectors, non-compliant waste emissions of pharmaceutical enterprises, as well as lack of public awareness toward rational use of antimicrobials. Bacterial resistance ultimately affects human health, but the cause of bacterial resistance and consequences are beyond the health sector. Antimicrobial resistance brings increasing biosecurity threats, worsens environmental pollution, constrains economic development and other adverse effects to human society, thus, there is an urgent need to strengthen multi-sectoral and multi-domain collaborative planning to jointly cope with this issue.
