Agriculture is highly exposed to climate change, as farming activities directly depend on climatic conditions. Agriculture also contributes to climate change through the release of greenhouse gases into the atmosphere. Two powerful ...ibute-to-highlight medbox">greenhouse gases are by-products of agricultural activity:
Methane (CH4) – from livestock digestion processes and stored animal manure;
Nitrous oxide (N2O) – from organic and mineral nitrogen fertilisers.
However, agriculture can also contribute to climate change mitigation by reducing greenhouse gas emissions and by sequestering carbon while maintaining food production.

The United Nations Framework Convention on Climate Change (UNFCCC) established its Financial Mechanism to facilitate the provision and transfer of resources from developed to developing countries. The 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.

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)

Agricultural ecosystems provide humans with food, forage, bioenergy and pharmaceuticals and are essential to human wellbeing. These systems rely on ecosystem services provided by natural ecosystems, including pollination, b...iological pest control, maintenance of soil structure and fertility, nutrient cycling and hydrological services. Preliminary assessments indicate that the value of these ecosystem services to agriculture is enormous and often underappreciated. Agroecosystems also produce a variety of ecosystem services, such as regulation of soil and water quality, carbon sequestration, support for biodiversity and cultural services. Depending on management practices, agriculture can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species. The tradeoffs that may occur between provisioning services and other ecosystem services and disservices should be evaluated in terms of spatial scale, temporal scale and reversibility. As more effective methods for valuing ecosystem services become available, the potential for ‘win–win’ scenarios increases. Under all scenarios, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities.

The COVID-19 pandemic has led to large increases in healthcare waste, straining under resourced healthcare facilities and exacerbating environmental impacts from solid waste. This report quantifies the additional COVID-19 healthcare waste generated, describes current healthcare waste management syst...ems and their deficiencies, and summarizes emerging best practices and solutions to reduce the impact of waste on human and environmental health. The recommendations included in the report build on actions in the WHO manifesto for a healthy recovery from COVID-19: prescriptions and actionables for a healthy and green recovery. They target the global, national and facility levels to promote a “win–win” scenario for COVID-19 PPE use, testing and vaccinations that are safe and support environmental sustainability.

Human use of land has been transforming Earth's ecology for millennia. From hunting and foraging to burning the land to farming to industrial agriculture, increasingly intensive human use of land has reshaped global patterns of biodiversity, ecosystems, landscapes, and climate. This review examines ...recent evidence from archaeology, paleoecology, environmental history, and model-based reconstructions that reveal a planet largely transformed by land use over more than 10,000 years. Although land use has always sustained human societies, its ecological consequences are diverse and sometimes opposing, both degrading and enriching soils, shrinking wild habitats and shaping novel ones, causing extinctions of some species while propagating and domesticating others, and both emitting and absorbing the greenhouse gases that cause global climate change. By transforming Earth's ecology, land use has literally paved the way for the Anthropocene.

Nationally determined contributions (NDCs) serve to meet the goals of the Paris Agreement of staying “well below 2°C”, which could also yield substantial health co-benefits in the process. However, existing NDC commitments are inadequa...te to achieve this goal. Placing health as a key focus of the NDCs could present an opportunity to increase ambition and realise health co-benefits. We modelled scenarios to analyse the health co-benefits of NDCs for the year 2040 for nine representative countries (ie, Brazil, China, Germany, India, Indonesia, Nigeria, South Africa, the UK, and the USA) that were selected for their contribution to global greenhouse gas emissions and their global or regional influence.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition...al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

The policy brief focuses on four key areas for intervention - air pollution, energy, transport and food systems. Air pollution causes 7 million deaths annually, and is a leading cause of both NCDs and climate 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.
