This paper evaluates the coupling coordination among these three benefits taking four Chinese autonomous municipalities as an example. These four cities have large-scale urban public...

The anaerobic biodegradability of domestic sewage for four Egyptian villages and four Egyptian cities was determined in batch experiments. The results showed that the biodegradability of the Egyptian-villages sewage (73%) was higher than that of the cities (66%). The higher biodegradability of the soluble COD of village sewage (69%) as compared to that of the cities (46%) was the reason for the...

In 2017, hot spot policing interventions were implemented in four cities Argentina: La Plata, Morón, Santa Fe and Tres de Febrero. Each intervention was similarly designed, organized implemented.

Urban forests are important components of societal interactions with nature. We focused on urban forest patches, a distinct and underexplored subset the that spans land uses ownerships, requires silvicultural practices to address their unique biophysical characteristics management regimes. Our goal was elucidate multi-scalar patch governance arrangements as they translated on-the-ground in four...
