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 international community sits at the tipping pointof a post-‐antibiotic era, where common bacterial infections are no longer treatable with the antibiotic armamentarium that exists. In South Africa, t...he identification of the first case of pan-‐resistant Klebsiella pneumoniae(Brink et al, J Clin Microbiol. 2013;51(1):369-‐72) marks a watershed moment and highlights ourtip of the antibiotic resistance ‘iceberg’ in this country. Multi-‐drug resistant (MDR)-‐bacterial infections, predominantly in Gram-‐negative bacteria such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosaand Acinetobacter baumanniiare now commonplace in South African hospitals. Whilst a number of expensive new antibiotics for Gram-‐positive bacterial infections have been manufactured recently (some of which are licenced for usein South Africa), no new antibiotics active against Gram-‐negative infections are expected in the next 10-‐15years. Hence what we have now, needs conserving

Early Childhood Matters is a journal about early childhood. It looks at specific issues regarding the development of young children, in particular from a psychosocial perspective. It is published twice per year by the Bernard van Leer Foundation.
On Page 54 of this issue the article titled: "Par...enting in times of war: supporting caregivers and children in crisis" can be found. In this article: Humanitarian interventions to support and guide parents and caregivers in times of war can mitigate the negative effects of violence and chaos on children and promote their resilience and development. This article highlights recent findings from the International Rescue Committee’s parenting programmes in Syria, underscoring the importance of such programmes not only in strengthening caregiving practices but also in addressing the psychological needs of parents.

This short paper aims to identify key evidence gaps in our knowledge of livestock- and fisheries-linked antimicrobial resistance in the developing world, and to document on-going or planned research initiatives on this topic by key stakeholders.
The antimicrobial resistant (AMR) infections in anima...ls that are of most potential risk to human health are likely to be zoonotic pathogens transmitted through food, especially Salmonella and Campylobacter. In addition, livestock associated methicillin resistant Staphylococcus aureus (LA MRSA) and extended spectrum beta lactamase E. coli (ESBL E. coli) are emerging problems throughout the world.

This paper presents lessons learned from previous flood responses in developing countries, based on a structured review of the literature. It is intended for people working in relief and recovery operations who have to decide if, when and how to intervene after a flood.
n Autumn 2013, HHI Executive Director, Vincenzo Bollettino, traveled to the Philippines to participate in an assessment of civil-military engagement in the humanitarian response to Typhoon Haiyan. The report was sponsored by the Center for Excellence in Disaster Management and Humanitarian Assistanc...e.
