In the major U.S. and European cities (e.g., Detroit, Seattle, San Francisco, London, Paris, etc.) that since 2007 have been feeling the effects of the international economic crisis, regeneration processes have been set up thanks, among other things, to the synergic impact generated by urban agriculture (UA). There are numerous and greatly varied effects, linked to localization, that are consis...

Novel biosurfactant-producing strains were isolated from hydrocarboncontaminated environments that exclusively utilize agro-waste as their primary carbon source for the expression of biosurfactants. These were quantified using various standardized methods. Among the agro-waste screened, Beta vulgaris (Beetroot) proved to be the most suitable substrate, for which the biosurfactants produced by t...

Simple sequence repeat (SSR) markers were used to characterize genetic diversity in 30 sorghum [Sorghum bicolor (L.) Moench] accessions conserved in the national gene bank of Botswana. This collection represents the three sorghum-growing agro-ecological zones in the country. Ten microsatellite primer pairs were used, and these generated a total of 53 alleles with three to seventeen alleles per ...

In Nigeria irrigated agriculture is an important tool for economic growth, food security, and poverty reduction during dry periods of rain-fed agriculture. The concentration and composition of dissolved constituents in water determines its quality for irrigation use. Water quality studies strongly suggest that agriculture is a leading source of water quality problems, due to pesticides and othe...

The application of agro-industrial waste in Aluminum Metal Matrix Composites has been getting more attention as they can reinforce particles in metal matrix which enhance the strength properties of the composites. In addition, by applying these agroindustrial wastes in useful way not only save the manufacturing cost of products but also reduce the pollutions on environment. This paper represent...

the response of clarias gariepinus to paraquat dichloride, a herbicide that is in high demand in the fragile niger delta ecological zone was investigated. the herbicide had been detected in most of the water bodies in the region. the fishes were exposed to the range of concentrations observed in the field (0, 2, 4, 6 and 8) µg/l for 28 days, conducted under the organization for economic co-oper...

one of the effective tools for identifying land resources and assign them to the best and most profitable forms of land productivity, susceptibility of agro-ecological zoning . in this study agro-ecological zoning of satellite imagery and gis were used. after agro-climatic zoning (based on isorain, isothermal and length of growing period maps) and agro-edaphic zoning (based on soil, slope and l...

The agro-biodiversity present in agro-ecosystems is fundamental guaranteeing sustainability and resilience. However, there are very few approaches for evaluating it and, even less, ones that include indicators to analyze the influence of structural spatial configuration a landscape order favor connectivity productive systems. There also no proposals management conservation practices, producer (...

In Africa, malaria is predominantly a rural disease where agriculture forms the backbone of the economy. Various agro-ecosystems and crop production systems have an impact on mosquito productivity, and hence malaria transmission intensity. This study was carried out to determine spatial and temporal variations in anopheline mosquito population and malaria transmission intensity in five villages...
