Requirements for Standard Ecological Survey Procedures in the MENA Region
Countries in the Middle East and North Africa region house a variety of ecosystems from the dense pine woodland of the Algerian coast to the extremely sparsely vegetated desert of Oman. Although cataloguing of flora and fauna in certain areas has been meticulously detailed, standard techniques for rapid assessment across the variety of habitats has not yet been established. Such techniques are ...

Mine pollution and salt marsh vegetation communities
Estuaries within Cornwall have been accepting metal-rich tailings and water from mining since the Bronze Age. Previous work at Camborne School of Mines has indicated that the floristic composition within contaminated salt marshes differs from characteristic British assemblages as defined by the National Vegetation Classification (NVC). Two communities not listed in the NVC system were discovered ...

The Sustainable Management of Metal-Rich Ecosystems: Lessons from an Historic Mining Area
In the absence of human intervention the ecosystem that develops on an historic mining site adapts to tolerate the particular set of environmental conditions that the mining activity has created. Often this naturally developed ecosystem is of high biodiversity value because only a particular assemblage of organisms can survive on such a stressed site. Stresses may be due not just to high ...

Industrial ecology: an overview
Industrial ecology is a young discipline that considers industrial and commercial enterprises as an ecosystem analogous to biological ecosystems. Its organising principle is that industrial systems should emulate the best features of biological ecosystems, thereby reducing energy and material consumption and waste generation. The benefits of such operations are reduced environmental damage and ...

Modelling undesirable outputs in eco-efficiency evaluation to paper mills along the Huai River based on Shannon DEA
There are a great number of DEA models proposed to deal with ecological efficiency problems with undesirable outputs. However, which model should be used in a specific scenario or how about the discriminability of a given DEA model is hard to decide in practice. This paper uses the ecological Shannon DEA procedure based upon the existing study to obtain an ecological comprehensive efficiency ...

How far are developing countries from the call of ecological tax reform? A review of environmental fiscal policy for Kenya
The main objective of this paper is to determine whether the ecological tax reform paradigm that hitherto is employed by a section of industrialised countries as an instrument of environmental management has potential applications in developing countries. The paper focuses on a case study of environmental management policy in Kenya and reveals that there is strong evidence of global environmental ...

Sustainability through the implementation of sustainable supply chain networks
Sustainability and sustainable development became two of the most popular expressions of our time in politics, science and business. However, a movement towards sustainability is only possible if companies develop concepts in production and logistics integrating both economic and ecological goals and measures. Managing sustainability seems to be more effective on a supply chain network level than ...

Ecologically-based approaches to evaluate the sustainability of industrial systems
Industrial ecology, promoted as a discipline of 'sustainability science', applies ecological concepts to industrial systems to improve their sustainability. Concepts such as diversity, food webs and nutrient recycling have been investigated for industrial systems. Complex systems theory may also prove to be an appropriate framework for industrial systems research. This framework can identify the ...

Development of an innovative conceptual model and a tiered testing strategy for the ecological risk assessment of rice pesticides
Rice paddies constitute a very special agrobiosystem, which for some circumstances, could be considered as a human driven wetland. The complexity of such dynamic systems is a key element for conducting ecological risk assessments, in addition, the proximity of rice paddies to areas of high ecological value must be considered. This paper presents a new conceptual model for conducting ecological ...

Input-output model based ecological risk assessment for ecological risk management of watersheds: a case study in the Taihu Lake watershed, China
To achieve advanced watershed ecological management, policy-makers have struggled to predict ecological impacts for a long time. As a process of ecosystem analysis, ecological risk assessment (ERA) has been widely adopted to analyse the possibility of adverse ecological effects. ERA has developed from considering only a few indicators in an area to multiple sources and receptors in ...

The use of traits‐based approaches and eco(toxico)logical models to advance the ecological risk assessment framework for chemicals
This paper presents a framework to diagnose and predict the effects of chemicals, integrating two promising tools to incorporate more ecology into ecological risk assessment, viz. traits‐based approaches and ecological modelling. Traits‐based approaches are increasingly used to derive correlations between the occurrence of species traits and chemical exposure from biological and chemical ...

The Impact of Metalliferous Mining on Salt Marsh Flora
Estuaries within Cornwall, UK have been accepting metal-rich tailings and water from mining for hundreds of years. Over time, saltmarsh ecosystems have developed on metal-rich sediments. Previous work at CSM has indicated that the floristic composition of these saltmarshes varies from characteristic British assemblages. Our hypothesis is metal-sensitive species are unable to colonise, leading ...
