WaterAid is an international NGO that provides assistance for safe water supply,
sanitation and hygiene practice in the poor communities in the world.
There is a broad consensus nowadays that the Earth is warming up as a result of greenhouse gas emissions caused by anthropogenic activities. It is also clear that current trends in the fields of energy, development and population growth will lead to continuous and ever more dramatic

climate change. This is bound to affect the fundamental prerequisites for maintaining good health: clean air and water, sufficient food and adequate housing. The planet will warm up gradually, but the consequences of the extreme weather conditions such as frequent
storms, floods, droughts and heat-waves will have sudden onset and acute repercussions. It is widely accepted that climate change will have an impact on the spread of infectious diseases in Europe, which is likely to bring about new public health risks in the majority of cases. Transmission of infectious diseases depends on a number of factors, including climate and environmental elements. Foodborne and waterborne diseases, for instance, are associated with high temperatures. Disease-transmitting vectors (e.g. mosquitoes, sandflies and ticks) are highly sensitive to climate conditions, including temperature and humidity; their geographical distribution will widen as climate conditions change, potentially allowing them to spread into regions where they are not currently able to live.
The primary purpose of this manual on climate change and infectious diseases is to raise the awareness and the level of knowledge of health workers at national, regional and local levels in the former Yugoslav Republic of Macedonia on the health risks associated with climate change and infectious diseases. This manual was devel-
oped as part of the WHO Regional Office for Europe project, Protecting health from climate change: a seven–country initiative, implemented with financial support from the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety.

hts and floods threaten the global food supply, humans are increasing their demands on water and land, The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.

parities between rich and poor, the joint global actions required to address climate change have been vigorously debated – and critical decisions postponed.
This document, part of WHO’s Health in the Green Economy series, describes how many climate change measures can be “win-wins” for people and the planet.
These policies yield large, immediate public health benefits while reducing the upward trajectory of greenhouse gas emissions. Many of these policies can improve the health and equity of people in poor countries and assist developing countries in adapting to climate change that is already occurring, as evidenced by more extreme storms, flooding, drought and heatwaves.
WHO’s Department of Public Health and Environment launched the Health in the Green Economy initiative in 2010 to review potential health and equity “co-benefits” of proposed climate change measures – as well as relevant risks.
This review examines mitigation strategies discussed in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change which constitutes the most broad-based global review of mitigation options by scientific experts.

l capacity to control the disease. Malaria is also one of the few health outcomes that has been modeled by more than one research group and can therefore facilitate the first model intercomparison for health impacts under a future with climate change. We used bias-corrected temperature and rainfall simulations from the Coupled Model Intercomparison Project Phase 5 climate models to compare the metrics of five statistical and dynamical malaria impact models for three future time periods (2030s, 2050s, and 2080s). We evaluated three malaria outcome metrics at global and regional levels: climate suitability, additional population at risk and additional person-months at risk across the model outputs. The malaria projections were based on five different global climate models, each run under four emission scenarios (Representative Concentration Pathways, RCPs) and a single population projection. We also investigated the modeling uncertainty associated with future projections of populations at risk for malaria owing to climate change. Our findings show an overall global net increase in climate suitability and a net increase in the population at risk, but with large uncertainties. The model outputs indicate a net increase in the annual person-months at risk when comparing from RCP2.6 to RCP8.5 from the 2050s to the 2080s. The malaria outcome metrics were highly sensitive to the choice of malaria impact model, especially over the epidemic fringes of the malaria distribution.

he Global Environment Facility became the first operating entity of the Financial Mechanism after the Conference of the Parties (COP) to the UNFCCC, and the GEF Council agreed to a Memorandum of Understanding (MOU) in 1996. This agreement placed the GEF under the guidance of the COP, as Article 11 of the Convention states that the Financial Mechanism “shall function under the guidance of and be accountable to the Conference of the Parties, which shall decide on its policies, program priorities and eligibility criteria related to this Convention.”
The yearly COPs have provided an opportunity for Parties to update and renew their guidance to the GEF. To date, there have been 145 UNFCCC COP decisions and 526 paragraphs that offer guidance to the GEF (see Table 1). In addition, the Conferences of the Parties serving as the meeting of the Parties to the Paris Agreement (CMA) have issued 40 decisions and 115 paragraphs as guidance to the GEF (see Table 2). Key areas of Convention guidance have included: the GEF’s role as an operating entity of the Financial Mechanism, including the Paris Agreement; the GEF’s institutional and procedural reform; transparency and access to GEF funds; country engagement and empowerment; reporting on greenhouse gas (GHG) inventories; support for technology transfer; and ongoing programming in mitigation and adaptation.

change, thus all interventions to reduce air pollution have a positive impact on both human and planetary health. In the energy sector, transition from fossil fuels to renewable energy is if vital importance to improving health, with mortality rates due to coal-generated electricity 1,000 times higher than for wind-generated electricity.
Promoting active transport such as walking and cycling in place of motorised transport has the dual benefit of reducing both air pollution and physical activity. Livestock production alone accounts for 18% of greenhouse gas emissions, with added emissions from food which are highly process and transported over long distances, and thus locally sourced plant based diets both prevent NCDs and promote human and planetary health.
