AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

An attempt has been made to develop Water Quality Index (WQI), using six water quality parameters at riverside stations located in the vicinity of temples of Dakshina Kannada district, Karnataka, South India. Rating curves were drawn based on the tolerance limits of inland waters and health point of view. Bhargava WQI method and Harmonic Mean WQI method were used to find overall WQI along the stretch of the river basin. Five point rating scale was used to classify water quality in each of the st...

Actual trends in papermaking concern on the use of recycled fibers and minimizing effluent volume by closing water circuit. Beside environmental and economic advantages, both trends can lead to serious problems in papermaking processes due to contaminants introduced with recycled fibers and their accumulation in closed water system. A key factor to avoid disturbances in the papermaking is to prevent the accumulation of detrimental compounds. In this respect, first it is necessary to find out met...

AbstractMunicipal solid waste (MSW) management is an important and challenging issue for sustainable development. It is also one of themost controversial problems and a subject of an ongoing debate between different interested parties. A particularly controversial issue is MSW incineration (with or without energy recovery) which has in many countries become a socially unacceptable option for dealing with solid waste. On the other hand, the increasing amounts of waste each year demand immediate a...

Abstract Effects of the aeration rate on nutrient removal from synthetic domestic wastewater using an intermittently aerated sequencing batch reactor (IASBR) were studied at ambient temperature. Two aeration rates, 0.8 and 1 L air/min, were studied. At the aeration-rate of 0.8 L air/min, removals of COD, NH4+-N, total nitrogen (TN) and PO43--P were 84%, 96%, 75% and 99%, respectively. At the aeration rate of 1 L air/min, removals of COD, NH4+-N, TN and PO43--P were 90%, 99%, 70% and 66%, re...

AbstractZarshuran As-Au deposit is the major ore deposit in northwest of Iran. Having been exposed to weathering, the accumulatedmining waste is consumed to deteriorate regional soil and water quality. Accordingly, 11 composite surface soil samples werecollected to evaluate the metallic pollution. Mean concentration of elements As, Sb, Hg and Zn were measured to be 234.9, 19.6,24.2 and 476.7 ppm, respectively. In comparison with mean earth crust and local guidelines for agricultural soil, the sa...

In this study, a database which holds data for wildfire emissions in Turkey for the last decade (between 2000 and 2009) was established in order to create a wildfire emissions inventory. The emissions of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), n...

In the Huai River Basin, pollutant masses are frequently concentrated into dams and sluices, which are subsequently discharged anddestroying the downstream ecology and environment. This phenomenon has been termed the specified paroxysmal water pollution incident (SPWPI), which has attracted worldwide attention as a large-scale water pollution problem. Studies of the formation mechanism of SPWPIs have become an urgent topic for fundamental research in water pollution prevention and control. I...

Anthropogenic influences on the hydrological network in the lower part of the Kolubara River have been notably intensive since 1959, when huge river regulation works were constructed to open new mining fields for lignite exploitation. From that moment, the Kolubara River flowed through the Pestan's riverbed (its right tributary), and the bank erosion became stronger, resulting in the lateral migration of the river course on one hand and land loss, land use changes, and economic consequenc...

The agri-food sector is more actively involved in these initiatives, because it offers the possibility to exploit waste and by-products, by adopting suitable biotechnologies. Such processes can be carried out either under aerobic conditions, for the production of compost, or anaerobically, for the production of biogas. In this work...

Multiple activities carried out on coastal areas expose marine sediments to contamination and their management has a great socio-economic importance with a high impact on economic development of coastal areas. However, there is an increasing shift towards the use of more sustainable approaches for managing ‘contaminated’ sediments. Using a case study of the Favignana Habour in Italy, this paper evaluates three approaches for the management of these sediments. The results of simulatio...

Agriculture is a highly water-demanding sector. Developed in recent years, the precision farming approach allows to optimize irrigation without compromising crops productivity. WSN networks are a key element of this approach because they allow to monitor continuously large number of parameters providing the possibility of a real-time intervention on field management practices. The WSN networks can be used to measure traditional parameters such as precipitation, soil moisture, or irradiation and ...

The scarcity of water resources, especially in the agricultural sector, is an increasing problem both in developing and industrialized countries. Recent studies and reports have shown the high potential of wastewater reuse mostly in South European countries. In this paper, we study the possibility to reuse wastewater from the Santerno full-scale wastewater treatment plant located in Imola (Bologna, Italy). Specific monitoring campaigns have been carried out in Basin 1 of the natural finishing tr...

In last years, a significant decline in soil quality has occurred due to contamination caused by anthropic activities. These lead to adverse changes in soil physical, chemical and biological attributes and drastically reduce soil fertility. There currently are no generally accepted criteria to evaluate changes in soil quality. This lack impedes the design and evaluation of meaningful soil management programs. This paper examines the principal physical, chemical and biological characteristics th...

Current landscapes have been intensively modified by humans and forest fragmentation has created substantial increases of forest edges. So far, scale-dependence between observable ecological patterns and the underlying processes affected by forest fragmentation have been widely ignored. To overcome the widespread ambiguity in selecting relevant spatial scales for studying the ecological effects of forest fragmentation, we investigated the effect of forest prevalence and edge length on carbon st...
