COVID-19 has heavily emphasized how contact tracing is crucial for managing outbreaks, and as part of the strategy for adjusting, and eventually lifting, lockdowns and other stringent public health and social measures. As the pandemic develops further, it will be a core measure to manage further wav...es of infection. In early June 2020, the World Health Organization (WHO) convened an online global consultation on contact tracing in the context of COVID-19, looking at the lessons of the pandemic to date; known and emerging best practices; and the measures necessary for urgent implementation, scale-up, maintenance and enhancement of contact tracing activities.

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.

The number of COVID-19 cases is on the rise again, with South Africa nearing half of all confirmed cases in the WHO African Region. Threats of new variants loom and low vaccination coverage raises questions on the future of the response to COVID-19. Prevention remains the key strategy in most sub-Sa...haran countries. Five National Centres (NCs) from the African Health Observatory Platform on Health Systems and Policies (AHOP), based in Ethiopia, Kenya, Nigeria, Rwanda and Senegal, reflect on lessons to be learnt from their containment responses in the initial phases. They construct timelines to highlight the policies and challenges associated with introducing a range of public health containment measures and
discuss the extent to which these measures continue to be valuable given the ever-changing nature of the pandemic.

Global Biodiversity Outlook (GBO) is the flagship publication of the Convention on Biological Diversity (CBD). It is a periodic report that summarizes the latest data on the status and trends of biodiversity and draws conclusions relevant to the further implementation of the Convention.
GBO-5 pro...vides global summary of progress towards the Aichi Biodiversity Targets and is based on a range of indicators, research studies and assessments (in particular the IPBES Global Assessment on Biodiversity and Ecosystem Services), as well as the national reports provided by countries on their implementation of the CBD. The national reports provide rich information about the steps taken in countries worldwide in support of biodiversity conservation, sustainable use, and the fair and equitable sharing of benefits. This body of Information provides a wealth of information on the successes and challenges in implementing the Strategic Plan for Biodiversity 2011-2020 and in reaching the Aichi Biodiversity Targets.
This Outlook draws on the lessons learned during the first two decades of this century to clarify the transitions needed if we are to realize the vision agreed by world governments for 2050, ‘Living in Harmony with Nature’.

he statistics in this report are from the Emergency Events Database (EM-DAT) maintained by the Centre for Research on the Epidemiology of Disasters (CRED) which records disasters which have killed ten or more people; affected 100 or more people; resulted in a declared state of emergency; or a call f...or international assistance.
In the period 2000 to 2019, there were 7,348 major recorded disaster events claiming 1.23 million lives, affecting 4.2 billion people (many on more than one occasion) resulting in approximately US$2.97 trillion in global economic losses.
This is a sharp increase over the previous twenty years. Between 1980 and 1999, 4,212 disasters were linked to natural hazards worldwide claiming approximately 1.19 million lives and affecting 3.25 billion people resulting in approximately US$1.63 trillion in economic losses.
Much of the difference is explained by a rise in climate-related disasters including extreme weather events: from 3,656 climate-related events (1980-1999) to 6,681 climate-related disasters in the period 2000-2019.

This report addresses the future of basic education, ICT use in deprived locations, and the use of ICTs in primary school learning in 2020 and 2025, especially in deprived contexts. It draws on research evidence from the literature, the authors’ experiences of ICT use in education initiatives, int...erviews with practitioners and academics, a workshop, and consultations with Save the Children staff from many different countries, mostly conducted in August 2017

Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19.
2020 was one of the three warmest years on record. The past six years, including 2020, have been the si...x warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle.
The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change.

February 2020Earth's Future 8(2):e2019EF001377.The water planetary boundary attempts to provide a global limit to anthropogenic water cycle modifications, but it has been challenging to translate and apply it to the regional and local scales at which water problems and management typically occur. We... develop a cross‐scale approach by which the water planetary boundary could guide sustainable water management and governance at subglobal contexts defined by physical features (e.g., watershed or aquifer), political borders (e.g., city, nation, or group of nations), or commercial entities (e.g., corporation, trade group, or financial institution).

Strengthening the capacities of SUN Countries by sharing and disseminating good practices in the fight against malnutrition.
This report is a summary of the results of the preparation and implementation of the Learning Route (LR) organized jointly by the SUN (Scaling Up Nutrition) Movement’s S...ecretariat, the Fight Against Malnutrition Unit (CLM, Cellule de Lutte contre la Malnutrition) and PROCASUR Corporation; this Learning Route was held in Senegal from the 26th of May to the 1st of June, 2014. The aim of this publication is to illustrate the experience, its main outcomes, and the lessons learned.

Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the ...role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate–disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

An IPCC Special Report on climate change, desertification,
land degradation, sustainable land management, food security,
and greenhouse gas fluxes in terrestrial ecosystems.
Compared to the previous five-year assessment period 2011–2015, the current five-year period 2015–2019 has seen a continued increase in carbon dioxide (CO2 ) emissions and an accelerated increase in the atmospheric concentration of major greenhouse gases (GHGs), with growth rates nearly 20% high...er. The increase in the oceanic CO2 concentration has increased the ocean’s acidity.
The five-year period 2015–20191 is likely to be the warmest of any equivalent period on record globally, with a 1.1 °C global temperature increase since the pre-industrial period and a 0.2 °C increase compared to the previous five-year period.
