“…Because of factors such as low organic matter content, saline or sodic soils, sandy or heavy clay soils, and low-permeability soil horizons, dryland soils can be challenging under the best of circumstances (Osman, 2018). Several of the food forest sites are in areas with a history of prior disturbance that added additional challenges, such as Stone Curves Cohousing, which was built on a site that had two buildings and driveways that had to be removed prior to development of their community.…”

Food forests are multilayered polycultures of mostly perennial species and an agroforestry practice well-suited to the urban environment. They are gaining increasing attention in temperate regions of Europe and the United States, but, to date, there has been little research on them in the American Southwest. In this study, we visited 14 food forests, all but two of which were in urban or peri-urban areas. At 12 of the food forests, we interviewed a person who established or manages them. The food forests span a significant range of the physical environments, types of communities, and ownerships found in the American Southwest. Despite challenges associated with the southwestern environment, such as the hot, dry climate and difficult soil conditions, we found clear evidence that food forests can be successfully established in the urban areas of this region. In addition to food production, these food forests are providing numerous other benefits such as mitigating the urban heat island effect, increasing local biodiversity, and improving the aesthetics of urban neighborhoods. While there is a need for additional research, a variety of networks and information sources have been established that are providing both practical information and inspiration for the establishment of additional food forests in the region. INTRODUCTIONFood forests, also known by names such as forest gardens, are multilayered polycultures consisting of mostly perennial species. They may include seven or more layers including overstory and midstory trees, shrubs, herbaceous species, ground cover plants, root crops, vines, an aquatic layer, and fungi (Butler et al., 2018;Crawford, 2010;Jacke & Toensmeier, 2005). Food forests are increasingly recognized as an agroforestry practice (Park et al., 2019;Gold & Garrett, 2021) along with the other temperate agroforestry practices of alley cropping, forest farming, riparian buffers, silvopasture, and windbreaks.Abbreviations: CRMPI, Central Rocky Mountain Permaculture Institute.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

Heavy metals and micronutrients assessment in soil and groundwater using geospatial analyses under agricultural exploitation in dry areas

2022

View full text Add to dashboard Cite

This study used a geospatial model to evaluate the regional distributions and buildup of various Heavy Metals (HM) and micronutrients as a result of groundwater irrigation used for lengthy periods in Egypt’s El-Kharga and El-Farafra oases, which were formed on western desert terrain, were the subject of the study. To fulfill this aim, field sampling of soil and groundwater was integrated with cartographic modeling. The evaluated HM concentrations in the water samples are below the permitted level for irrigation. The surface soil’s element concentrations were within acceptable limits. However, protracted mobility and a potency risk for soil smearing were not spotted. The apportionment of HM concentricity versus soil profundity showed that the assemblage was primarily in the topsoil. Future management plans should consider ongoing HM level monitoring. The lands are divided into three classes: II, III, and IV, according to their capabilities, while the soils are divided into three classes based on their suitability: moderately suitable class S2, marginally acceptable class S3, and permanently unsuitable class N2. Additionally, soil fertility and quality were categorized into low and moderate categories. Land evaluations indicate that they are promising areas for agricultural investment under the conditions of using modern agricultural techniques. The most important results of the study are that the non-technical use of irrigation water in some areas has exacerbated the problems of salinity, especially in those where the drainage characteristics are poor. Concentrations of HM were found only in agricultural areas adjacent to urban areas and poor drainage, especially in agricultural areas reclaimed for more than 50 years. High concentrations of HM were also found in shallow wells close to the same places, and there were no significant concentrations in blind wells. The main recommendation of the study is the necessity of using modern agricultural and irrigation systems in those places.
