CompostCommunityOrganic cycleUtilising Agricultural Waste To Enhance Food Security And Conserve TheEnvironment
2012E.N. Sabiiti · · Uganda
This paper reviews how agricultural wastes can be utilized to enhance food security and conserve the environment, focusing on developing countries like Uganda. In Kampala, over 1000mt of waste accumulate daily, with only 30% collected. The study highlights that these organic wastes, rich in nutrients, can serve as a bio-resource for smallholder farmers to improve soil nutrient status and crop yields, such as vegetables and maize, and enhance milk production. This approach also reduces environmental pollution and poverty.

2011Zikrullah Safi, Martina Předotová, Eva Schlecht, Andreas Buerkert · Journal of Plant Nutrition and Soil Science · Afghanistan (Kabul)
A two-year study in Kabul, Afghanistan, measured horizontal flows of C, N, P, and K, and leaching losses of N and P in 21 vegetable gardens, 18 cereal fields, and vineyards. The findings suggest that soils in extensive cereal fields are at risk of N and K depletion, vegetable gardens face K depletion, and vineyards may be oversupplied with nutrients, potentially contributing to groundwater contamination. These results merit verification.
Environmental trade-offsOrganic cyclePeri-urban agricultureWaste management and peri-urban agriculture in the early modern Scottish burgh
2011Richard Oram · Stirling Online Research Repository (University of Stirling) · United Kingdom
This paper reviews geoarchaeological evidence and analyzes documentary records from 17 Scottish burghs to explore waste management and peri-urban agriculture in early modern Scotland. The study illustrates the central role of urban waste as manure in burgess agriculture. Burgh regulations revealed changing cultural attitudes towards waste in the 17th and 18th centuries, but urban waste remained in demand as fertilizer in the hinterland of many Scottish towns until the late 19th century.

2011Sinan Koont · University Press of Florida eBooks · Cuba
This chapter examines technological innovations in protected and semi-protected urban agriculture cultivation in Cuba. Greenhouse cultivation was initially introduced for import substitution in tourism, with adaptations for tropical conditions and agroecological pest control. Semi-protected cultivation, using shade-providing screens, later replaced protected cultivation as a subprogram, and polycultures have been effectively reintroduced in semi-protected organóponicas. The program is rapidly expanding with government support.

2011幸治 江口 · Institutional Repositories DataBase (IRDB) · Japan
The Santome Area in Saitama Prefecture has practiced circular urban agriculture utilizing plain woods for 300 years, but urbanization, particularly in Kawagoe City and Tokorozawa City, is causing a significant decline in farmland and plain woods. While the Ministry of Agriculture, Forestry and Fisheries and Saitama Prefecture promote urban agriculture and plain wood preservation, the plain-wood-utilizing circular urban agriculture in Santome Area faces specific problems. This paper identifies land systems, including taxation, as a central issue among these problems and examines the possibility of integrated preservation for farmland and plain woods.
