Dumping of excess salt Salt deposits from irrigation
Concentrated brines and salt deposits can accumulate as a result of irrigation on saline soils and/or using water with relatively high amounts of dissolved salts. Continuation of productive land use may require disposal of excess saline residues. Commonly proposed is dumping into local salt lakes or pumping into saline aquifers, or even freshwater watercourses. These methods, together with continuation of the original irrigation practices, degrade the land and can carry other serious environmental impacts which are rarely considered.
The Mexican Environment protection agency observed a fish kill caused by a spill of over four million gallons of brine waste from a plant in Laguna Ojo de Liebre in may 1998.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
