• Nationally Determined Contribution and its adaptation targets to build climate resilience of sectors such as health, water management, urban infrastructure and settlement, which are vulnerable to the adverse impact of climate change. 

Context

UNEP-DHI Partnership presents a series of 6 webinars that will give an introduction to the basic challenges and issues related to water quality.

Join our CTCN Consortium Partner, the Tropical Agricultural Research and Higher Education Centre (CATIE) for this introductory webinar on technologies for adapting to climate change in the water sector.

TAHAL Group International BV makes Master plans feasibility studies detailed design financial studies technical assistance and training project and construction supervision turnkey/BOT projects GIS and MIS studies environmental impact assessment. TAHAL's comprehensive approach to integrated water resources development has been implemented successfully in Israel and worldwide resulting in sustainable solutions to meet existing and future demand. As a major player in the water sector for over 60 years the company has helped provide clean and safe water to millions of people worldwide.

General description EN GIBTON’S ClayMix is based on proprietary patented technology of Micelle-Clay and Organo- Clay complexes mixed with Sand- Clay creating multi-layer granular media mixtures. Anionic neutral and same cationic dissolved contaminant molecules are adsorbed into the complexes and removed from .water during filtration or settling processes. ClayMix treatment systems appear as two market products: adsorption-filtration system and adsorptionsettling system.

Background: As petroleum consumption continues to rise the world is turning to unconventional oil sources such as kerogen shale and bituminous sands in order to keep up with global demand. Satellite imagery gravity meters and magnetometers are typically used to pinpoint ideal locations for drilling over conventional oil or gas reserves. However differentiating unconventional oil sources from other layers of rock is difficult due to their similar densities so instead organic biomarkers are used to trace hydrocarbons (and their by-products) back to their source rock.

Background: Water is crucial for human survival. Water is also a pivotal aspect of the global economy for its uses in agricultural irrigation industrial processes electricity production and as drinking water. Continuous population growth limits the supply of freshwater. Because water conservation alone cannot resolve the problems of the shrinking water supply production of fresh water from alternative sources such as reclaimed wastewater brackish groundwater and ocean water is imperative. Currently osmotic processes are able to produce high quality water from these sources.

Artificial Aquifer Tube-well is an innovation to treat contaminated surface water for domestic use on the saline-prone coast and arsenic & iron contaminated parts of Bangladesh. The recharging structure resembles the natural underground aquifer, which is the source of groundwater.

Ecological sanitation ('ecosan') is the reuse of human excrement, which contains the nutrients required to fertilise land.
