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.

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

The authors conduct an integrated survey of Antimicrobial Resistant Organisms (AMR) in drinking water, wastewater and surface water in three settings in Bangladesh: rural households, rural poultry farms, and urban food markets. Results show that untreated water discharged from rural households, poul...try farms and urban markets are major contributors to surface water pollution and antibiotic resistant bacteria genes, calling for increased surveillance and monitoring.

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.

The Lancet Planetary Health Volume 6, ISSUE 4, e342-e349, April 01, 2022. Human impacts on earth-system processes are overshooting several planetary boundaries, driving a crisis of ecological breakdown. This crisis is being caused in large part by global resource extraction, which has increased dra...matically over the past half century. We propose a novel method for quantifying national responsibility for ecological breakdown by assessing nations’ cumulative material use in excess of equitable and sustainable boundaries.

We need to be concerned about mental health in the context of climate change
Female genital mutilation is a harmful traditional practice that violates girls’ right to health
and overall well-being. Most research cites social acceptance, marriageability, community
belonging, proof of virginity, curbing promiscuity, hygiene, and religion as motivations for the
practice. I...t is generally assumed that individual attitudes of parents and other family mem-
bers have an impact on decisions related to the cutting of girls, and that such attitudes are
influenced by social norms. The aim of this study is to understand how parental attitudes
towards the practice of female genital mutilation influence decision making related to the cut-
ting of girls.

The marathon to eradicate polio is on its final lap: the world is more than 99% of the way to success. After millennia of living with poliovirus and suffering the paralysis it causes, today nearly all the world’s people live in polio-free countries; two of the three strains of wild poliovirus (WPV...) have been eradicated. Some 20 million people are walking who would have been paralysed had it not been for the efforts of national governments and health workers. If eradicating polio has been a marathon, the finishing line is in sight.

Epidemics of infectious diseases are occurring more often, and spreading faster and further than ever, in many different regions of the world. The background factors of this threat are biological, environmental and lifestyle changes, among others. A potentially fatal combination of newly-discovered ...diseases, and the re-emergence of many long-established ones, demands urgent responses in all countries. Planning and preparation for epidemic prevention and control are essential. The purpose of this “Managing epidemics” manual is to provide expert guidance on those responses.
