L'eau potable et les services d'assainissement et d'hygiène (WASH) sont essentiels à la prévention des 17 maladies tropicales négligées (MTN) pour lesquelles une intensification de la lutte ou l'élimination sont prévues à l'horizon 2020.
La fourniture d’eau potable et de services d’...assainissement et d’hygiène est l’une des cinq interventions clés inscrite dans la feuille de route mondiale contre les MTN. Pourtant, à ce jour, la composante WASH de la stratégie n’a reçu que peu d’attention et le potentiel lié à la mise en commun des efforts WASH et MTN reste largement inexploité.
Des efforts ciblés sur la composante WASH sont nécessaires de toute urgence pour atteindre les cibles de la feuille de route mondiale contre les MTN.

GUIDE PRATIQUE À L’INTENTION DES PROGRAMMES DE LUTTE CONTRE LES MALADIES TROPICALES NÉGLIGÉES
This toolkit provides step-by-step guidance to NTD programme managers and partners on how to engage and work collaboratively with the WASH community to improve delivery of water, sanitation and hygien...e services to underserved population affected by many neglected tropical diseases. The toolkit is based on real-life programme experience, which users can match to their needs and local context. It includes a series of tools to help build multisectoral partnerships, mobilize resources, and design, implement and evaluate interventions.

PlosOne https://doi.org/10.1371/journal.pone.0165797; Food production is a major driver of greenhouse gas (GHG) emissions, water and land use, and dietary risk factors are contributors to non-communicable diseases. Shifts in dietary patterns can therefore potentially provide benefits for both the en...vironment and health. However, there is uncertainty about the magnitude of these impacts, and the dietary changes necessary to achieve them.

This paper explores access to water, sanitation, and health in pastoral communities in northern Tanzania. It argues that the concept of gender, used on its own, is not enough to understand the complexities of sanitation, hygiene, water, and health. It explores pastoralists’ views and perspectives ...on what is ‘clean’, ‘safe’, and ‘healthy’, and their need to access water and create sanitary arrangements that work for them, given the absence of state provision of modern water, sanitation, and hygiene (WASH) infrastructure. Although Tanzania is committed to enhancing its citizens’ access to WASH services, pastoral sanitation and hygiene tend to be overlooked and little attention is paid to complex ways in which access to ‘clean’ water and ‘adequate sanitation’ is structured in these communities. This paper offers an intersectional analysis of water and sanitation needs, showing how structural discrimination in the form of a lack of appropriate infrastructure, a range of sociocultural norms and values, and individual stratifiers interact to influence the sanitation and health needs of pastoralist men, women, boys, and girls.

Increasing human demand for water and changes in water availability due to climate change threatens water security worldwide. Additionally, exploitation of water resources induces stress on freshwater environments, leadi...ng to biodiversity loss and reduced ecosystem services. We aimed to conduct a spatially detailed assessment of global human water stress for low to high environmental flow (EF) protection.

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.

Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies have monitored APIs in rivers, these employ different analytical methods, m...easure different APIs, and have ignored many of the countries of the world. This makes it difficult to quantify the scale of the problem from a global perspective. Furthermore, comparison of the existing data, generated for different studies/regions/continents, is challenging due to the vast differences between the analytical methodologies employed. Here, we present a global-scale study of API pollution in 258 of the world’s rivers, representing the environmental influence of 471.4 million people across 137 geographic regions. Samples were obtained from 1,052 locations in 104 countries (representing all continents and 36 countries not previously studied for API contamination) and analyzed for 61 APIs. Highest cumulative API concentrations were observed in sub-Saharan Africa, south Asia, and South America. The most contaminated sites were in low- to middle-income countries and were associated with areas with poor wastewater and waste management infrastructure and pharmaceutical manufacturing. The most frequently detected APIs were carbamazepine, metformin, and caffeine (a compound also arising from lifestyle use), which were detected at over half of the sites monitored. Concentrations of at least one API at 25.7% of the sampling sites were greater than concentrations considered safe for aquatic organisms, or which are of concern in terms of selection for antimicrobial resistance. Therefore, pharmaceutical pollution poses a global threat to environmental and human health, as well as to delivery of the United Nations Sustainable Development Goals.

The Lancet Planetary Health Volume 6, ISSUE 5, e388-e390, May 01, 2022. As the Stockholm Declaration on the Human Environment turns 50, the role of the health stakeholder community in forward-looking environmental agendas is more important than ever. Breathing air, drinking water, and eating food i...s a daily requirement for healthy human bodies. These basic needs inextricably link human health to the health of our environment. Hence, core elements of the global environmental movement were built on concern for the negative impact of pollution on human and ecosystem health.

These guidelines deal specifically with water, sanitation and hygiene, and are designed to be used in schools in low-cost settings in low- and medium-resource countries to:
• assess prevailing situations and plan for required improvements;
• develop and reach essential safety standards as a f...irst goal; and
• support the development and application of national policies.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.
