Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

The Infection Prevention and Control (IPC) Legal Framework comes before the Specialized Technical Committee on Health and Drug Control for adoption and endorsement. The IPC Legal Framework is designed to guide Member States in the review and strengthening of laws and policies that support IPC at bot...h the national level and in healthcare facilities. In developing this IPC Legal Framework, the Africa Centres for Disease Control and Prevention (Africa CDC)
is furthering its mandates to harmonize disease control and prevention policies and promote the prevention and control of diseases by building capacity of public health institutions in Members States.

Mortality due to enteric infections is projected to increase because of global warming; however, the different temperature sensitivities of major enteric pathogens have not yet been considered in projections on a global scale. We aimed to project global temperature-attributable enteric infection mor...tality under various future scenarios of sociodemographic development and 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).

Cascading risks from rising prices and supply disruptions, April 2022.
Global resource markets are still reeling from the impacts of Russia’s invasion of Ukraine; the two countries are major suppliers of energy, food and fertilizers. Supply disruption and the sudden imposition, in response to the... crisis, of unprecedented economic sanctions, trade restrictions and policy interventions have caused prices of commodities to skyrocket.
Before the conflict, demand for global resources already exceeded supply and drove up prices as economies rebounded after the COVID-19 pandemic. This gave rise to a global cost-of-living crisis, characterized by increasing levels of energy and food poverty. This situation is likely to become much worse as a consequence of the war in Ukraine, and poses a threat to human security, particularly among low-income and vulnerable populations.

Kiel Policy Brief, Ukraine Special 1, March 2022.Many African countries heavily rely on imports of agricultural commodities and agricultural inputs from Ukraine and Russia, for example wheat, other grains, and fertilizer. Russia’s invasion of Ukraine has disrupted global access to grains due to re...duced production, exports, and increased trade costs. This policy brief investigates the possible long-term consequences of the conflict on food security in Africa

The Investment guidelines for youth in agrifood systems in Africa, developed jointly by FAO and the African Union Commission (AUC) through a multi-stakeholder and participatory process, highlight the importance of youth as change agents and key stakeholders contributing to sustainable agrifood syste...ms. The guidelines aim to accelerate investments in and by youth in agrifood systems by providing practical guidance - including tools and examples - to design, develop, implement, monitor and evaluate youth-focused and youth-sensitive investment programmes and to engage youth fully as partners in the entire process.

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.
