Emerging contaminants in water: Regulation in Mexico, precautionary principle and comparative perspective

Body

This paper analyzes the status of legal regulation of emerging contaminants in water sources in Mexico. To this end, its relevance is debated in the context of the constitutional obligations assumed regarding the human right to water and sanitation (HRWS). The international instruments are reviewed and a brief general balance is prepared that allows us to reflect on the legal vacuum of this topic in Mexico. Emerging contaminants are shown to be substances of diverse origin and chemical nature, the presence of which in the environment is not considered significant due to their distribution and concentration, so they go unnoticed. However, due to the increase in their detection, the potential ecological impact and the risks they pose to human health, they have received recent attention in academic analysis, official studies and water quality policies. It is proposed, from the perspective of comparative law and under the precautionary principle approach, a scheme of national normative regulation, for that purpose, a comparative analysis is carried out with the Chilean and European legal frameworks. It is concluded that the absence of devices that regulate emerging contaminants hinders compliance with HRWS, especially that which refers to two central aspects: adequate sanitation and the supply of quality water for domestic consumption.

WEFE-SENEGAL - Cadre Logique du Projet

Body

Nous vous prions de trouver ci-attache le nouveau cadre logique du projet WEFE-SENEGAL. 

Il a ete modifie suite a la reunion recente avec le processus ROM et pour tenir compte de dernieres modifications des activites sur le projet (activite sur la qualite de l'eau, dialogues NEXUS autour des fiches du PARACI, ...) ainsi que de la situation sanitaire mondiale affectant les pays riverains et l'Europe. Le document restera pour le moment prive aux membres du groupe.

Cordialement,

CLIMATE VARIABILITY AND EXTREME EVENTS ANALYSIS IN THE ZAMBEZI RIVER BASIN USING STANDARDIZED PRECIPITATION EVAPORATION INDEX AND L-MOMENTS

Body

The Zambezi River is a very important water resources with its catchment area covering most parts of Southern Africa. It is a habitat to a wide range of plant and animal species. Humanity in
this region just like other animals depend on water from the Zambezi River and its tributaries. Its dependence ranges from provision of potable water, agriculture, power, manufacturing, mining, tourism and many other sectors (World Bank 2010). With such benefits from the river, the human population is proved to be rapidly increasing. For example, an annual increase of 3.9% in Africa (the highest in the world) has been recorded with most of the increase in the Southern part of the continent, which is mostly covered by this basin (World Bank, 2010). Despite the population boom, industrialization and urbanization, not all Africans have access to clean water and sanitation. Water availability varies from country to country as some parts of Southern
Africa receive very low mean annual rainfall (Namib and Kalahari deserts) and low river flows with others receiving very high precipitation (areas in the sub tropics) hence high river flows.
With this in mind, more water is needed to meet the increasing demands in clean water, sanitation, irrigation, power (Hydroelectric) and many for factors increasing the demand (O Serdeczny et al.,2016).
