Cities are increasingly challenged in sustaining their growing populations with food. As fossil energy reserves are depleted, the sustainability of food production is highly dependent on the ability to yield more food relative to resource use. In preparing cities for peak oil, urban food systems are therefore needed that make better use of local and renewable resources, as opposed to imported a...
Environmental pollution constitutes a great health hazard to human, animals and plants with local, regional and global implications. Pollution has adverse effects on land, water and its biotic and a biotic components. Effluents from industries are normally considered as the main industrial pollutants containing organic and inorganic compounds The increasing agricultural reuse of treated effluen...
BACKGROUND The U.S Department of Agriculture (USDA) recently made substantial changes to the school meal standards. The media and public outcry have suggested that this has led to substantially more food waste. PURPOSE School meal selection, consumption, and waste were assessed before and after implementation of the new school meal standards. METHODS Plate waste data were collected in four ...
Abstract Use of green agronomic techniques for plant development and crop protection is essential environmental sustainability. The current research investigates a more efficient long-term technique manufacturing silica nanoparticles (SiO 2 NPs) from agricultural waste (sugarcane bagasse corn cob). SiO NPs were synthesized by calcinations residues in muffle furnace with varying temperatures (40...
This work addresses environmental problems connected with biowaste management, the chemical industry, and agriculture. These sectors of human activity cause greenhouse gas (GHG) emissions in air, climate change, leaching excess mineral fertilizers applied to soil into ground water, eutrophication. To mitigate this problem agriculture, controlled release (CRFs) are made by coating granules synth...
Worldwide, a huge production of agro-industrial wastes is observed every year in the milling, brewing, agricultural, and food industries. Biochemical bioactive substances can be produced from these agricultural wastes. Pineapple by-products, which consist peeled skin, core, crown end, etc., account for 60% weight pineapple fruit are disposed as waste, causing disposal pollution problems. The bi...
Cities are a key system in anthropogenic phosphorus (P) cycling because they concentrate both P demand and waste production. Urban agriculture (UA) has been proposed as a means to improve P management by recycling cities' P-rich waste back into local food production. However, we have a limited understanding of the role UA currently plays in the P cycle of cities or its potential to recycle loca...
