AbstractThe paper discusses some environmental problems caused by the presence of the copper mining and processing complex in the Bor area (Eastern Serbia). The Bor area is a serious hot spot in Serbia. Unsupervised operation of the mining company RTB Bor, without any protective measures, has led to extreme pollution of the Bor River, the Danube and underground waters, soil pollution with heavy metals, air-pollution with sulfur-dioxide etc. Recommendations are suggested as follows: a sustainable...

The January 2010 earthquake in Haiti caused catastrophic damage, and the displacement of about 1.5 million people in urban and peri-urban areas of Port-au-Prince. A web-based questionnaire was developed and sent to international organizations working in Haiti through the Water, Sanitation and Hygiene (WASH) Cluster in order to assess how humanitarian actors responded to the sanitation needs for Internally Displaced People (IDP). The findings showed different sanitation systems being implement...

Convergence, that is the concentration of human populations into small areas, has been common throughout history. However, convergence has now reached historically unprecedented levels. Historically, convergence has tended to increase the long-term risk to humanity caused by many factors, including the associated environmental damage. Large cities appear to be at greater risk of unforeseen disasters, and may even collapse when some maximum sustainable size is exceeded. Based on a review of publi...

Natural disasters from earthquakes can cause considerable damages, with potentially severe effects to urban environment. Last strong Vrancea earthquake on March 4, 1977 (Mw=7.4, depth=95km); tens of thousands of buildings damaged, many people injured and dead. Strong earthquakes in the Vrancea zone occur between 60-200 km depth within an almost vertical column. Bucharest Earthquake Early Warning (EEW) system detects earthquakes with a seismic network in the epicentral Vrancea region and issue a ...

The global renewable energy share should reach and exceed 30% by 2030. Mini-scale hydropower installations are environmentally-friendly technologies, unlike large hydroelectric power plants that have certain drawbacks from the environmental point of view. A safe and clean solution is the cross-flow turbine, but the commercial types require a minimum head, usually captured by additional hydro-technical works that can also damage the environment. In this context, a very good solution could be a lo...

The research was conducted in a spruce stand with disseminated beech and larch trees from the Carpathian Mountains, where thinning operations had taken place. The CTL (Cut-To-Length) system was applied by using harvester and forwarder. The research was aimed at determining the amount of damage to trees, identifying the damage types, their frequency, extent, form and distribution at the level of trees and at the level of the entire stand. Thus, 7.5 % of remaining trees were damaged with the am...

Timber harvesting and log extraction with conventional ground-based skidding systems in steep, mountainous terrain often results in severe damage to residual stands and forest sites. In this study, the impact of rubber-tired skidders on standing trees along sides of the trails was investigated 5 to 20 years post-harvest in terms of frequency and development of decay at the points of wounding. The study was located in the Hyrcanian mountainous forests of Iran. All standing beech trees (healthy or...

The artifacts, as part of our cultural heritage, are exposed to fungal attack. Fungi can cause irreversible damage to the artifacts, resulting in economic, aesthetic and historical loss. The use of chemicals for the elimination of fungal biodeteriogens is currently a controversial subject, due to the potential toxic effect on human health and environment. The aim of this paper is to study the potential antifungal effect (on “environmental moulds”) of a series of extracts from nati...
