Summary The subject of this dissertation is the ecological compensation principle and its use as a means of addressing the impacts of road construction. More specifically, it offers a critical examination of how the principle has been applied in the context of the planning and construction of the Dutch ‘national’ roads, i.e. motorways and other trunk roads. The study was conducted over two periods at: ● the Institute of Environmental Sciences of Leiden University (1995-1996); ● the Road and Hydraulic Engineering Division of the Directorate-General of Public Works and Water Management (1997-2004). The dissertation consists of three parts. Part 1 (Chapter 1) situates the basic issues and elaborates the specific research questions addressed. In Part 2 (Chapters 2 to 7) these questions are treated in detail in six articles published between 1996 and 2003 in international and Dutch journals; Chapter 8 summarizes the results of these articles. Part 3 first discusses several problematical and as yet unresolved aspects of the ecological compensation principle (Chapter 9). This discussion and the formulated general conclusions lead to a number of recommendations as to how the policy framework of the compensation principle might be refined to improve the effectiveness with which it is applied in the context of national road- building as well as possibly other development projects (Chapter 10).This chapter ends with the perspectives of the compensation principle and summarising conclusions of this dissertation. Part 1: Introduction Chapter 1 outlines the background of the Dutch ecological compensation principle, its consequences for the Directorate-General of Public Works and Water Management, Rijkswaterstaat, the government agency responsible for its practical implementation, and the problems and research questions addressed in this dissertation. 9 Summary Prior to its implementation in the context of transportation infrastructure projects in 1993, the principle of ecological compensation had already been applied informally and ad hoc for a number of years in other policy areas in the Netherlands, notably forestry and land use. With the publication of the National Structure Plan for the Rural Areas, in 1993, the ecological compensation principle was formally introduced as an element of national policy. It is to be applied in relation to several categories of designated nature area, principal among them the areas comprising the Ecological Main Structure. The Structure Plan sets out a phased planning and decision-making procedure involving both the initiator of the project in question and the competent authority. The first phase involves weighing up the perceived need for the project and its anticipated benefits against the projected loss of ecological values. This phase is steered by the principle of ‘no unless’ and culminates in a basic decision on whether or not the project may go ahead. In principle, no developments may be implemented in protected areas. If on the basis of the information emerging in this phase approval is withheld, the formal procedure is concluded. If the project is approved, given its perceived overall benefits to society, and it is anticipated that the ecology of the area concerned will suffer in any way as a result, the procedure moves into its second phase. In all cases measures must then be taken to mitigate the ensuing damage and, to the extent that such steps are inadequate, measures taken to compensate any remaining damage. The stated aim here is ‘no-net-loss of ecological values’. Ecological compensation thus plays an important role in both key phases: ● in project planning and decision-making, through improved input of conservation interests; ● in implementation of projects that have received government approval. This gives rise to a policy ‘ladder’ that in the course of project development seeks successively: ● to avoid ecological impacts, ● to mitigate any unavoidable impacts, i.e. reduce their severity, ● to compensate for any impacts that may then remain, aiming at a physical ‘zero-sum’ equation, ● financial compensation. In the context of national road projects, avoidance of ecological damage means the road either not being granted approval after due consideration of its merits or 10 Summary being displaced horizontally or vertically to prevent ecological impact.
