Abstract Food production hinges largely upon access to phosphorus (P) fertilizer. Most fertilizer P used in the global agricultural system comes from mining of nonrenewable phosphate rock deposits located within few countries. However, contained livestock manure or urban wastes represents a recyclable source P. To inform development recycling technologies and policies, we examined subnational, national, spatial patterns for two intersections land use affording high potential: (a) manure‐rich...
This paper redefined the agricultural production system and its subsystems with respect to phosphorus (P) flow improve assessment of use efficiency (PUE), which is a key indicator for P security sustainability water resources. It also assessed inflows, outflows, PUE in crop-pasture subsystem, livestock subsystem overall present comparative picture these systems across various nations. (averaged as 46% selected thirteen nations) lower compared 72%) but higher than 18%). Nations high usually...
This study analyzed Brazil’s Climate-Smart Goods (CSG) trade from 2000 to 2023. While overall expanded significantly, CSG trade, though growing, remains a small fraction. A persistent deficit in CSGs indicates reliance on imported sustainable technologies and limited domestic production. Despite fluctuations, has shown steady growth, suggesting growing alignment with global sustainability goals. However, constitute portion of exports, highlighting untapped potential the sector. These...
Understanding how cities can transform organic waste into a valuable resource is critical to urban sustainability. The capture and recycling of phosphorus (P), other essential nutrients, from human excreta particularly important as an alternative fertilizer source for agriculture. However, the complex set socio-environmental factors influencing management not yet sufficiently integrated sustainable P research. Here, we synthesize information about pathways take through sanitation systems...
This paper presents an overview of MSW management in Chittagong, the second largest city Bangladesh. The total generation Chittagong increased steadily from 538 tons/day 1999 to 984 2005 and 1890 tons/ day 2009. collection coverage City Corporation 45% 64% 2008 almost 70% Approximately 72% (952 tons) daily collected 2009 were disposed as unsanitary landfilling 27.62% (365 open dumping; while, only 0.16% (2,116 kg) managed through systematic recovery recycling.
Abstract Phosphorus (P) is central to food production. Current understanding about the global phosphorus system dominated by studies in wealthier nations where soil fertility, fertilizer supply chains, and agronomic tracking have long been established. In contrast, developing are experiencing major agricultural transitions associated flows remain a significant knowledge gap. We compiled analyzed several years of recent datasets for Bangladesh, currently eighth most populous nation, using...
In this study, we have investigated the amplitude and intensity of traffic induced noise at sensitive institutions Chittagong city in Bangladesh. The study has been conducted covering four types (for instance: schools, colleges hospitals) from each three deliberately selected wards (administrative areas) out 41 city. Maximum minimum sound levels all average ranged 65.84 to 79.69 dB 59.73 69.03 respectively. 12 different institutions, exceeded safe limit (45 dB) as set for such colleges,...
The amplitude and intensity of traffic-induced noise at the environmental setup educational institutions in Chittagong City, Bangladesh were investigated. Average maximum minimum sound levels study area ranged from 65.46 to 82.24 dB 60.63 70.89 dB, respectively. Noise all studied exceeded safe limit (45 dB) as prescribed by Department Environment, World Health Organization. Sound showed a significant (P = 0.000) declining trend with increase distance source noise. Among noise-induced...
