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.

Consolidating Earthquake Safety Assessment Efforts in India. This document provides succinct instructions on how to perform rapid visual screening (RVS), a quick method of earthquake assessment of buildings. It covers a brief description of RVS and its role as a simplified qualitative assessment in ...the wider methodology of earthquake assessment of buildings, and the recommended forms for pre-earthquake and post-earthquake Level 1 Assessments for seven building typologies. The method recommended by the primer is the BMTPC method which provides both Seismic Safety Index and Performance Rating to a particular building.

Some 32% of internally displaced persons (IDPs) in Ukraine suffer from post-traumatic stress disorder (PTSD) as a result of the conflict in the east.
Among the 2,203 respondents surveyed across Ukraine, the study also found a high prevalence of mental disorders such as depression (22%) and anxiety ...(17%), particularly among women. This has a significant effect on family and community relations, the ability to work or even do basic tasks such as walking.
Moreover, the study noted that 74% of respondents in need of psychiatric care do not receive it, mainly due to a high cost of mental healthcare and medicine.

Climate change is one of the biggest crises of our time. Climate threats range from higher temperatures, heavy rainfalls and floods, erratic precipitation, droughts, desertification, and land degradation. This has negative implications on the quality and quantity of natural resources, such as land a...nd water, agricultural productivity, rural livelihood options, food prices, and nutrition security, particularly when there is a lack of adaptation capacities and preparedness measures (Pacillo, 2024). Farmers are at the forefront of the climate crisis where their livelihoods are being jeopardized, and they are faced with many challenges to secure water, energy, and agriculture inputs, and maintain agriculture productivity. This heightens the risk of competition over natural resources and aggravates grievances and structural inequalities related to land rights and ownership as well as land access, management, and governance. In Africa, land-related issues are among the triggers of many violent disputes (Medina et al, 2024). For instance, communal violence in Nigeria and Sudan is tied to competition over scarce fertile land and poor resource governance (Bruce and Bourdeaux, 2013).
