Precision application of water for peri-urban horticulture
2007Viola Devasirvatham, P. S. Cornish · International Journal of Water · Australia
Peri-urban horticulture in Australia requires irrigation for year-round vegetable production. Subsurface Drip Irrigation (SDI) offers higher water use efficiency and crop yields, with the potential to reduce environmental risks from drainage and runoff. However, SDI has potential disadvantages, including poor germination or crop establishment and uneven wetting patterns. Research is needed to solve these problems and enable environmentally acceptable vegetable production.

2007Bernard Keraita, Flemming Konradsen, Pay Drechsel, Robert Clement Abaidoo · Tropical Medicine & International Health · Ghana
The effectiveness of low-cost irrigation methods (drip irrigation kits, furrow irrigation, and watering cans) in reducing contamination of lettuce irrigated with untreated wastewater in urban farming in Ghana was assessed. Analysis of 396 lettuce, 72 soil, 15 poultry manure, and 32 water samples revealed that lettuce irrigated with drip irrigation kits had the lowest contamination levels, with an average of 4 log units per 100g fewer thermotolerant coliforms than those irrigated with watering cans. However, drip kits often clogged, required lower crop densities, and restricted other routine farm activities.

2006Alice J. Hovorka, Damell Smith, R. van Veenhuizen · · Global
This article argues that a gendered perspective on urban food security is essential to understand dynamics shaping food production and marketing in urban centers. It highlights that failing to explore women's distinct roles risks leaving gender inequities and food supply hindrances unaddressed, countering the invisibility of women's work often assumed as automatic domestic duties. The article emphasizes women's significant role in domestic food supply, even in societies with minimal household food production, citing examples like Latin American women organizing to address urban hunger.

2004Rocío García Bustamante, John Butterworth, M. Flierman, Daniel Herbas, Melvin Hollander, S. van der Meer, P. Ravenstijn, Magaly Reynaga, Gustavo Zurita · · Bolivia (Tarata)
In 2002, Tarata, Cochabamba, Bolivia, experienced violent conflicts over the right to use water from the Laka Laka dam for urban agriculture. The dam was intended for large-scale irrigation and domestic use, but not urban productive uses, leading to disputes when the urban population sought water for homestead cultivation. Although 5% of the reservoir yield was allocated for urban supply, its poor quality prevented drinking use, prompting the community to organize for its use in irrigating small plots, despite opposition from irrigation farmers.

2004Brian Halweil · · Global
This book points out that the long-distance food system consumes staggering amounts of fuel, generates greenhouse gases, and compromises food security. Since 1961, the tonnage of food shipped between nations has grown fourfold, with food in the United States typically traveling 1,500 to 2,500 miles from farm to plate. While this system often runs roughshod over local cuisines, varieties, and agriculture, a local-foods movement is beginning to emerge globally.
