In the Caribbean, kitchen gardens are categorized into home gardens and food forests, both grown on home plots. Home gardens are small areas for short-term crops, used for home consumption and sharing, while food forests are low-maintenance agroforestry systems with diverse plant species, including fruit trees and non-food hardwoods. These systems mimic a forest's vertical structure.

Introducing disaster-chain theory for mine ecological environments, this paper classifies the secondary ecological-environment destruction chains originating from ground collapse — affecting land, climate, water and artificial ecological environments — into five types, and further divides their interaction mechanisms into seven kinds across four classes. At the Siding lead-zinc mine, 280 collapse pits were brought under control based on ecological restoration and reorganized into landscape ecological function areas comprising urban agriculture and economic forest zones, restoring farmland and 8.47 hectares of forest land. The results indicate the proposed disaster-chain analysis is feasible and could offer a new approach for controlling ground collapse in mining areas.

A baseline survey in Khartoum city, Sudan, from September to November 2007, assessed the insecticide susceptibility of 9820 Anopheles arabiensis specimens across 6 urban and periurban sites. The mosquito was susceptible to bendiocarb, propoxur, fenitrothion, deltamethrin, and lambda-cyhalothrin. However, susceptibility rates for malathion, DDT, and permethrin differed significantly between urban and periurban sites, and 50% knockdown times were significantly higher in periurban populations for deltamethrin, lambda-cyhalothrin, and malathion.

An educational program using soil seed banks was developed to promote ecological literacy among children. A pilot application with 4th-6th grade students found it most effective for 4th graders in ecological knowledge and attitude, but the initial period (late March to early November) was too long. The final program was shortened to 3 months and 2 weeks (late March to early July) and targeted 4th graders, consisting of seven activities including sampling, setting, observing, and identifying seedlings.

This study focused on implementing a functional rooftop garden using biochar and the microbial consortium BM-S-1. Biochar amendment reduced heavy metal (Pb and Zn) runoff and maintained more moisture to stimulate plant growth, but it did not maintain NO3- and PO43-. The amendment of biochar and BM-S-1 somewhat inhibited the growth of broadleaf liriope, while biochar amendment increased tolerance to storm carrying salt.

An assessment of Cuban urban agriculture's production and distribution outcomes finds that the most successful subprogram is fresh vegetable production, which has grown rapidly island-wide, while other subprograms remain active but less developed. Distribution occurs through thousands of points-of-sale, MALs, self-provisioning, and MAEs, with social consumption at workplaces, hospitals, and schools. Urban agriculture plays a significant role in improving Cuban diets but has not led to food sovereignty; other outcomes cited include employment generation, environmental benefits, and community building.
