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.

Background report
This document provides guidance on interventions to prevent vaccine-preventable disease outbreaks in the context of mass population movement resulting from the ongoing crisis in Ukraine.
The war in Ukraine has rapidly taken the form of a series of conflicts in urban contexts. Urban warfare has a long history, but unfortunately, we can see from this conflict just how topical it remains. Generally, a first phase involves imposing a siege and forcing the city to surrender by making liv...ing conditions impossible.

The Arid and Semi-Arid lands (ASAL) constitute about 80% (467,200 sq. km) of Kenya’s total land mass and is grouped into geographical zones including the Savannah covering most of the North- eastern and South-eastern parts, the Coastal region, the North Rift Valley, the Highlands and the Lake Vict...oria Basin. The ASAL host about 35% of Kenyas population (13 million people) and over 60% of its inhabitants live below the poverty line, subsisting on less than one US dollar per day.

Globally, levels of hunger remain alarmingly high. In 2021, they surpassed all previous records as reported by the Global Report on Food Crises (GRFC), with close to 193 million people acutely food insecure and in need of urgent assistance across 53 countries/territories, according to the findings o...f the GRFC 2022. This represents an increase of nearly 40 million people compared to the previous high reached in 2020 (reported in the GRFC 2021).
