In recent years, water management in irrigation systems has become increasingly complex. The main factors contributing to this situation are: (1) higher crop yields in existing schemes are possible only with precise water-management methods that are in tune with the prevailing agricultural practices and social customs; (2) increased competition for water and the seriousness of the side effects of irrigation (soil degradation, waterlogging, salinity etc) have made it necessary to manage water supplies more carefully and to give more attention to drainage; (3) greater cooperation among farmers and improved irrigation scheme management have become prerequisites for scheme operation and maintenance.
Operational research into the management of irrigation systems now supports performance monitoring systems. To husband water supplies more carefully, there are computer models for enhancing irrigation design and operation at field and system level. In addition, better methods and approaches are bing developed to increase farmers' participation and train scheme staff.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
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.
