No-till farming Ridge till cultivation Mulch-till approach to land preparation
Cultivating without ploughing by leaving the residue from the previous year's crops in place to hold soil and moisture, then scratching or chiselling-in seeds, which sprout through the decomposing residue. Crop rotation is used to break down insect cycles. Weeds are controlled by new systemic herbicides that quickly break down.
It 1993, it was predicted that new legislation requiring conservation in the USA is likely to push up the proportion of cropland under some kind of residue management from its current figure of 25% to around 50% within two years. By the end of the century it was likely to be around 80%. It was also reported that farmers engaged in this agricultural revolution were finding increases in yields and a reduction in the cost of producing crops of 25-30%.
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.
