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.

During the pandemic, Brazil has provided its citizens with support in the areas of long-term care and disability, the labor market, social assistance, education, and pensions. This report focuses on two social policy areas, health-care and family benefits (including labor policies), as these were th...e most crucial social policies implemented in Brazil during the Covid-19 pandemic in terms of the resources allocated and the magnitude of social impact. Brazil’s relatively generous social policies were uncoordinated with public health interventions, which contributed to poor compliance with these public health interventions. This suggests that social policy initiatives alone are insufficient in mitigating the social consequences of the pandemic. They need to be accompanied by and coordinated with public health measures, including regulations on testing, social distancing and mask wearing.

Using an ensemble of climate models and socioeconomic scenarios, WRI scored and ranked future water stress—a measure of competition and depletion of surface water—in 167 countries by 2020, 2030, and 2040. We found that 33 countries face extremely high water stress in 2040 (see the full list). We... also found that Chile, Estonia, Namibia, and Botswana could face an especially significant increase in water stress by 2040. This means that businesses, farms, and communities in these countries in particular may be more vulnerable to scarcity than they are today.

Rapport sur les populations clés.
Au cours de la dernière décennie, les données de séquençage génétique des agents pathogènes ont gagné en importance et contribuent désormais de façon déterminante à la détection et à la maîtrise des flambées de maladies infectieuses, en facilitant la mise au point de ...produits de diagnostic, de médicaments et de vaccins et en guidant lesactivités de riposte aux flambées(1-11). L’émergence du nouveau coronavirus, par la suite désigné « coronavirus 2 du syndrome respiratoire aigu sévère » (SARS-CoV-2), a encore accentué l’importance des données de séquençage génétique.

Reducing the humanitarian impact of the use of explosive weapons in populated areas is a key priority for the United
Nations, the International Committee of the Red Cross (ICRC), civil society and an increasing number of Member States.
The United Nations Secretary-General has expressly called on... parties to conflict to avoid the use in populated areas of
explosive weapons with wide-area effects.
While the use of explosive weapons in populated areas may in some circumstances be lawful under international
humanitarian law (IHL), empirical evidence reveals a foreseeable and often widespread pattern of harm to civilians,
particularly from explosive weapons with wide-area effects.
Many types of explosive weapons exist and are currently in use. These include air-delivered bombs, artillery projectiles,
missiles and rockets, mortar bombs, and improvised explosive devices (IEDs). Some are launched from the air and
others are surface launched. Whilst different technical features dictate their accuracy of delivery and explosive effect,
these weapons generally create a zone of blast and fragmentation with the potential to kill, injure or damage anyone
or anything within that zone. This makes their use in populated areas – such as towns, cities, markets and camps for
refugees and displaced persons or other concentrations of civilians – particularly problematic. The problems increase
further if the effects of the weapon extend across a wide-area either because of the scale of blast that they produce; their
inaccuracy; the use of multiple munitions across an area; or a combination thereof.
