Climate Change 2021: The Physical Science Basis. Contribution of Working Group I to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change
The Scientific Conceptual Framework for Land Degradation Neutrality (LDN) provides a scientific foundation for understanding, implementing and monitoring LDN. It has been designed to create a bridge between the vision and the practical implementation of LDN, by defining LDN in operational terms. The... conceptual framework is a product of the UNCCD Science-Policy Interface.

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.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

The Atlas of health and climate is a product of this unique collaboration between the meteorological and public health communities. It provides sound scientific information on the connections between weather and climate and major health challenges. These range from diseases of poverty to emergencies... arising from extreme weather events and disease outbreaks. They also include environmental degradation, the increasing prevalence of noncommunicable diseases and the universal trend of demographic ageing.

Sudan has a long history of hosting refugees and asylum seekers with 991,787 individuals, 51 per cent female and 53 per cent children, expected to live in Sudan by the end of 2020.
The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum parasites in Africa. Its objectives are to: i...) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

Climate change presents significant challenges to human health and biodiversity. Increased numbers of extreme climate events, such as heat waves, droughts or flooding, threaten human health and well-being, both directly and indirectly, through impaired ecosystem functioning and reduced ecosystem ser...vices. In addition, the prevalence of non-communicable diseases is rising, causing ill health and accelerating costs to the health sector. Nature-based solutions, such as the provision and management of biodiversity, can facilitate human health and well-being, and mitigate the negative effects of climate change.

Women have less access to the development services and support – such as adequate healthcare, education and
modern technology – that make people more resilient to climate change and other shocks and stressors.2
Women’s unequal access to resources, their disproportionate responsibility for ca...re of dependents (typically unpaid),
and the insecurity and precariousness of their paid labour all contribute to the feminisation of poverty and women’s
heightened vulnerability to climate hazards. Climate change is a multiplier of existing vulnerabilities and threatens to
reverse hard-earned development gains for all people, and particularly for women.
