This research explored how insects can add value to urban farming by up-cycling waste streams into high-grade nutrients and compost, focusing on their use as animal feed. Through expert interviews with urban farming practitioners and pet owners (165 respondents, 59 in urban environments), a concept was developed for growing black soldier fly larvae on organic waste to replace meat in carnivorous animal diets, specifically for dogs. Over half of urban respondents indicated no municipal green waste pickup, and over 50% practiced urban farming.

The 2009 tomato late blight pandemic in the eastern United States resulted in significant crop losses for many home gardeners and organic producers. This event led to widespread questions regarding its causes and differences from previous epidemics.

D. Z. Phillips, Heather I. Sullivan · ISLE Interdisciplinary Studies in Literature and Environment · United States

This collection of essays for ISLE assesses the material aspects of healthy economies, environments, and bodies, arguing that the traditional economic-ecological "health" dichotomy is insufficient. It finds that the determination of "healthy" is complex, as artificial environments can be benign, and even a flourishing community garden can have neglected produce going to waste. The essays explore how a large number of healthy human bodies can be detrimental to healthy environments.

This FAO study, conducted for the SAVE FOOD! congress at Interpack 2011 in Düsseldorf, estimates that roughly 1.3 billion tons of edible food produced globally is lost or wasted each year. It finds large regional disparities in per capita consumer-level food waste: 95-115 kg/year in Europe and North America versus only 6-11 kg/year in sub-Saharan Africa and South/Southeast Asia. Combined per capita food losses and waste across the supply chain are reported at 280-300 kg/year in Europe and North America versus 120-170 kg/year in sub-Saharan Africa and South/Southeast Asia.

This study analyzed agricultural land use changes in peri-urban Yogyakarta from 1996-2007, covering 922.17 ha in Sleman, 1,888.60 ha in Bantul, and 1,082.79 ha across 47 villages. Factors like agricultural production exchange value, irrigated land, built area percentage, population density, education, and land price significantly influenced land change rates, which negatively correlated with distance from the city. However, agricultural land percentage to village area, land tax, and dummy variables for Bantul and Kulon Progo did not significantly influence these rates, and the changes negatively impacted regional food loss, availability, and farming sustainability prospects.

This study aimed to establish a methodology for using solar dryers for food and seed preservation under rustic conditions. It was established that condiments and seeds can be dried in approximately 3 days, maintaining their qualities and offering additional sanitary advantages. The manufacturing of solar dryers is very simple and does not require large investments.

The 2000 Food Recycling Act, pushing food businesses to reduce waste and recycle it into feed and fertiliser. Sets per-industry recycling targets and certifies 'recycling loop' plans — the legal frame for running food-scrap composting as a business.

In Ethiopia, urban agriculture faces significant challenges due to government disapproval of public land use for farming and difficulty in obtaining credit. A 1983 survey in Addis Ababa found that 17% of 1352 households produced their own food on less than 25 sq. meters, with 90% of non-farmers citing lack of land. Despite urban agricultural cooperatives demonstrating 70% higher member income, their lack of government legalization prevents access to loans for productivity improvement.
