Treating pest infestation of crops Destroying crop pests and diseases
This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities.
Pest management is the domain of entomologists, ecologists, biologists, agriculturalists, toxicologists and chemists. The subject is highly complex and a multidisciplinary approach seems necessary. Unfortunately, however, there has been a tendency for each specialist to only consider his/her own discipline, thereby ignoring the numerous interactions between the dynamics of pest populations, the environment, crops, etc. Far preferable is that agricultural pest management be always viewed in its ecological context and that the whole farming system is studied before it is manipulated with external pest control measures, particularly toxic chemicals. The usual approach to pest management is pest-oriented rather than crop-oriented. However, since crops are more important than pests, a more direct approach to pest management is likely to be experimental variation of crop management rather than of pest control possibilities, and emphasis on data on cropping systems characteristics rather than on pest populations.
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.
