In Sri Lanka owing to the geology, rainfall patterns, land use etc. there is considerable variance in the quality of groundwater. Water quality issues include salinity, hardness, certain minerals such as Fe, Mn, Fluoride, agricultural pollution etc. The required water treatment technology is too expensive for rural water supplies and as a result, often the groundwater source is rejected. The North Central Province, a predominant paddy cultivation area, is plagued with chronic kidney disease (CKD). CKD is present in areas where the groundwater is hard and contains high Fluoride.

Portugal and Spain share five river basins – Minho, Lima, Douro, Tagus and Guadiana – and for this particular situation the two countries have developed cooperation mechanisms on water management.

Change in weather patterns, deforestation and settlements in high risk areas are reasons for landslides and soil erosion. The following solution describes a technical measure that is cost efficient and easy-to-implement. It is a way to prevent erosion on slopes and roads and to protect roads, houses and land from landslides. Used car tires are piled up along an insecure hillside. These tires are filled with a mixture of sand and cement to prevent the flow of water, which would affect the construction.

In Latin America (LA) there are a number of knowledge institutions with a high level of technical expertise and with a long experience in the water sector. Although cooperation between some LA research institutions and countries exists, this is not usually the case in the whole continent.

Today, across the world there are over a billion people living in extreme poverty without the basics.
