Research paper thumbnail of Preparation and implementation of seven ecological compensation plans for Dutch highways

Decision-making on the seven projects took place between 1993 and 1995. Specifically, we considered: (a) the processes employed to prepare and implement the compensation plans; (b) the methods used to identify, plan, and execute the compensation measures; and (c) the results yielded by these methods. We conclude that the CPs were prepared fairly uniformly, particularly in terms of the processes and methodologies used to derive compensation measures. Five of the seven CPs had become operational by 2001 and initial experience is now being gained on land acquisition and transfer of compensation sites to nature conservation trusts. Further progress of CPs is likely to be seriously hampered by growing demand for land for development in g...

Research paper thumbnail of Supply of environmental information for decision support

The decision process is an interactive process where the results from one type of analysis can lead to the demand for more information. The shown framework makes a distinction between concepts and tools as suggested by the LCANET working group on Positioning and Application of LCA (Cowell et al., 1997; Wrisberg and Gameson, 1998). Concepts are defined as an idea on how to achieve sustainability, such as life cycle thinking, design for the environment, and cleaner technology. Tools, on the other hand, are operational methods supporting the concepts. They are structured vehicles for reasoning, analysis and communication. Analytical tools, provide technical information as to the consequences of a choice, while procedural tools focus on procedures to guide the way to reach a decision. All types of tools are supported by technical elements, such as mass balance models, evaluation models and quality assessment. The technical elements may also stand alone to be used to support the decision process. The technical elements are supported by data. Figure 3.1 Framework for the supply side.

The reason is that it is not clear for which problems a specific tool is most appropriate, or whether more than one tool should be applied, especially in determining the net overall effects of any given decision. Furthermore, it is a reaction to the fact that we often find a gap and a lack of communication between the developers of such tools — typically stemming from academic research — and the users of tools from industry and government. Such lack of co-ordination can lead to situations where tool developers dedicate a huge amount of resources to create highly sophisticated tools that find little practical application, and at the same time industry is lacking instruments to meet the steadily increasing demand for environmental evaluation.

Research paper thumbnail of Livestock depredation and mitigation methods practised by resident and nomadic pastoralists around Waza National Park, Cameroon

We assessed this conflict in Waza National Park, Cameroon, in 2008 through an interview survey. A total of 207 resident and 174 nomadic pastoralists were interviewed. Results indicated high levels of livestock depredation around the Park, with attacks occurring most often at night. Lions were economically a substantial threat accounting for total losses of EUR 100,000 per annum. Per household, resident pastoralists lost one cow and nomadic pastoralists two cows per annum, equating to c. EUR 260 and 520, respectively. To mitigate these losses resident pastoralists used enclosures for nocturnal protection of their livestock more than nomadic pastoralists, who tended to herd livestock more during pasture. Improved mitigation methods pertaining to herding practice, the use of enclosures and the presence of ...

This group convened the day after the 8th LCA Case Studies Symposium in Brussels, Dezember 1, 2000. There was not enough time during this meeting to discuss the new scheme in detail, which contained an additional Area of Protection (AoP) or Safeguard Subject (SaSu) Life Support System (LSS). This new AoP or SaSu has been suggested in order to represent the partly inanimate subsystems of the ecosystem earth which are the basis for live on this planet, as we humans know it and are part of it. These systems (e.g. the stratospheric ozone layer, the climate system and the biogeochemical cycles or the fertility of soils) are in general not considered to have a societal value in itself, but rather to be supportive for the immediately convincing SaSus or A...
