1. Introduction: Aims and Scope
This study is the result of a commission from the French regional authority of the Franche-Comté region, the “DREAL”, Direction Régionale de l’Environnement, de l’Aménagement et du Logement, (French regional directorate for environment, planning and housing)  . This public commission concerns an appraisal of the comprehension of the capacity and efficiency of Territorial Tools of Land Management (TTLM) by stakeholders and their impact on resilience against flood risks  -  .
In fact, this study comes in a general context of changes in public policies concerning risks especially within the European countries  . Numerous and active public policies concerning flood management within the European Union (following the 2007/60/EC Directive) are often related to international decisions like the recent conference of Hyogo on natural disaster prevention. As shown in scientific literature  -  , management agencies have conducted for a long time proactive risk prevention policies generally inscribed within institutional areas, in territories, at local as at national scale. Local hazard management aims to obtain a better knowledge and awareness of risks as previously done for the constitution of natural conservation areas  -  . Thus this evolution is related to a global context of water policy  .
In France, the Barnier Act of 1995 (Law no. 95-101) provides an institutional framework with the “Plan de Prévention des Risques” (PPR or plan to manage the prevention of risks). A PPR is a local tool usefully integrated into urban planning decisions taken by local councils when the national authority requires it. However, relations between these Territorial Tools of Risk Prevention (TTRP) and land management policies are well known. Most of the research literature highlights the means to perform the analysis of risks more than the efficiency of these policies  -  . However, recent news about natural disasters point out the necessity to upgrade these policies to understand how to improve the resilience of the territories against flood risks     .
Emergency Management considers resilience essential for safeguarding communities or building safer communities. The goal of disaster risk management is to guarantee minimal loss of life and livelihoods and to allow the affected community or system to return to “normal” within the shortest possible time  . The resilience definition adopted here is: “a process linking a set of adaptive capacities to a positive trajectory of functioning and adaptation after a disturbance”  . As shown in current literature  -  resilience can be defined and measured by focusing on three attributes: maintenance of structure and function in the face of disturbance, ability to self-organize in response or anticipation to disturbance and capacity for learning and adaptation. Prosser and Peters  claim that to support a disaster-resilient community, studies must focus on prevention, preparedness, response and recovery. In the case of territorial systems, these attributes integrate the understanding and the awareness of the population and especially stakeholders managing the territory  . Risk and territorial tools perception and awareness are huge parameters of resilience    .
Because of the European legislation and its different enforcement provisions in national policies (Table 1), frameworks and methodologies of practitioners influence the way to enhance the resilience of territories  . Moreover, progress in land and flood management is not made to create new methods or theories but it may lead to an appropriate use of existing ones, indicating a need for simpler methods that provide satisfactory results.
A researcher trying to develop suitable methods for practical use should be conversant with the daily context of risk management practitioners  . Thus, knowledge of the range of territorial tools  is certainly one main way to upgrade the resilience against flood risks, and points out the question of acceptance  and perception  . Finally, there are few empirical and local studies of risk analysis  , and it seems to be the same concerning an evaluation of TTLM and TTRP.
In order to document the relations between these territorial tools and the ability of local authorities to achieve resilience, the study focused on a very representative territory specifically impacted by flood hazards. Conducted through questionnaires, this paper is organized as follows: Section 2 presents the studied field, Section 3 the methods used to evaluate the level of knowledge and the deficiencies, Section 4 the results. In Section 5, the

results are discussed with a special focus on possible implications of the conclusions.
2. Location of the Study―Geographic Area Scope and Nature of Risks
The target territory is the Urban Area of Belfort-Montbéliard-Delle-Héricourt (UABMDH) neighbouring Switzerland (Figure 1). It is well known because it is the manufacturing area of the Peugeot Company, it is a territory marked by strong issues related to prevention of flooding. Located between the Vosges and
The hydrographic network is traversed by rivers whose flows are generally not weighted and marked by an interannual irregularity. If water seems abundant in these fluvial axes, they are often oriented towards spasmodic conducts. Without being torrential, they are predisposed to large variations of flow resulting in floods and overflows that the current climate change trends reinforce. Flooding seems to be one of the frequent features of fluvial dynamics for rivers with strong anthropic floodplains.
The hydrographic system is highly hierarchized within the urban area and dominated by the Allan, the Doubs and the Savoureuse rivers that converge around the city of

set of highly ramified valleys or channels flowing in wide floodplains. In fact, there is a real convergence of the river system towards Montbéliard that increases the risk of flooding in the UABMDH area.
With 307,666 inhabitants in 2007 for 1240.5 km2 and with 199 towns  , the density of the area is more than twice the French average density with 248 inhabitants/sq∙km. This high density is related to the large number of medium-sized and small cities and reinforced by a rural scattered settlement where minimum densities are rarely below 50 inhabitants/sq. km. It could be explained by the presence of major firms like Peugeot or Alstom and their industrial plants. The 1990’s flood cost ?00 million, especially because of damage caused to their infrastructures. Consequently, ?0 million were invested by local authorities to prevent future floods from occurring  .
Otherwise, as already and most often demonstrated   , urbanization in areas like UABMDH increases the risk of flooding. Furthermore, our survey underlines a real culture of flooding and its management throughout the territory. The question is how to improve the efficiency of territorial tools evaluated by local stakeholders in order to maintain and improve territorial resilience.
The aim of our method is to evaluate what are the perceptions of risks due to flood. This aim is integrated in a global diagnosis of the resilience of the territory (Figure 2)  . The basis of this method requires conducting an investigation of how the populations and especially public policy makers or contributors appreciate:
・ Risks, due to floods,
・ Direct risks due to local flooding events,
・ Systemic risks, due to the consequences of the public territorial policies, specialized in flooding management and other ones,
・ The efficiency of these policies.
As shown in Table 1, there is a complex organisation in land management documents. Our aim was to evaluate knowledge of these documents by local stakeholders and particularly by policy makers. The method used is to develop a diagnosis protocol for a territory by investing in previously collected data but also by immersing ourselves in the territory in order to meet a range of local actors (Figure 2). The aim of this immersion is to form an idea of ways of perception and appropriation of the territorial instruments so called public policies tools by the stakeholders of the community as defined by Boon et al.  .
First of all, the study gathered data about the demographic compositions, the economic activities and the location of all 199 towns in the area  . Conventional data drawn from statistical resources from the French national institute, INSEE, made it possible to determine backgrounds in order to provide statistical studies  . From this panel of 199 towns, we selected 88 in order to provide personal interviews with stake holders (Table 2). The choice of the 88 towns is related with the composition (demographic, localisation from floodplains, public policies tools) of the 199 with respect of the best representativeness of our sample  . 235 stakeholders provide statistical is a line and is integrated to a town of the 88 of the area. Our study is designed as a qualitative questionnaire transformed in a quantitative study. We collected data in the field in November 2012: 31 persons provided the questionnaires of the 235 respondents.
We also used a GIS analysis in order to value the location of each local town in order to underline whether it is relevant to flooding hazards. The most simple and relevant criterion is the distance of the town, and especially its core, from the axis of the floodplain  . The analysis done of these elements of backgrounds was translated into an index:

where β is the shortest distance of the town from floodplains and δ is the total population of the local community. In order to smooth the values, we added coefficients. The largest demographic size of the towns is related to the proximity to a river: the biggest cities such as Belfort (50,128 inhabitants), Montbéliard (25,974 inhabitants), Sochaux (4027 inhabitants), etc. are near the flooding plains of Savoureuse and Doubs (Figure 1 and Figure 3). On Figure 3, is represented the relation between the population of the towns with their distance to a floodplain: this relation is weak (R2 = 0.3) but it is significant. Because flooding areas are especially near rivers, we gave more weight to the location. Thus, in order to show the impact of proximity in the vulnerability evaluation, the λ Index gives a more significant value of the distance from a floodplain than the population.
After taking into account the context of the UABMDH and its vulnerability issues and gathering a collection of statements from local actors, it is possible to:
・ Evaluate the panel of territorial and regulatory tools (like PPR) and other implemented territorial tools used for example for planning,
・ Evaluate the level of appropriation and inclusion of these tools,
・ Evaluate the level of awareness and consideration of flooding and drought hazards.
Stakeholders were identified using in formations obtained from DREAL. We contacted the stakeholders by mail and then by telephone in order to arrange a time for a face-to-face interview. The basis of our research was not just a questionnaire sent out but a real interview. The questionnaire was used to approach respondents’ perceptions of risks and of tools to plan the prevention. Initially more than 500 stakeholders were contacted for an interview. Finally, the panel concerned 235 persons representative of the local population and especially public stakeholders (Table 3) and the sample of the stake holders concerned the 88 towns. All items of the questionnaire were pretested with students (see acknowledgements). Based on pretested results, items were rejected and

new items were included. The research utilized a three-contact procedure: initial mailing, telephone contact for appointment and local interview. 31 persons―students and teachers―did the interviews for two weeks in the field. Every interview was conducted in the UABMDH area. The words and statements were coded as “ 0” or “ 1” , which made it possible to produce statistics  . Especially it was possible to provide the index of vulnerability with the answers of the stake holders as explained lower.
One of the study aims is to understand awareness of environmental policies by stakeholders involved in local management or activities. A questionnaire including nine topics was submitted to 235 different stakeholders to measure flood risk awareness (Table 3). Nonetheless, it implied that the population has a significant appreciation of hazards, both local and global.
The data collected by means of questionnaires were transformed into statistical values. For example, the feeling of vulnerability was classified into 5 levels, from 1= very low feeling of vulnerability, to 5= strong feeling of vulnerability. Such an index is the mix of three parameters determined by the questionnaire:
・ Knowledge or perception of the frequency and intensity of floods on the territory,
・ Feeling of vulnerability of the territory due to local flood hazards,
・ Appreciation of global risks due to consequences for the local territory.
The value of the index is the mean value of these three approach of the vulnerability for each stake holders.
This paper focuses on the risks, and two questions are studied: how local stakeholders evaluate whether their town may be concerned by floods and, on the other hand, whether they know and appreciate usual tools of public policies, as shown in Table 1.
Most of our questionnaires were submitted to local representatives followed by administrative workers, private workers, inhabitants and association members (Table 3). In total, 235 respondents correspond to 88 towns and local councils selected on the 199 ones of the territory. The work sought to explore the opinions and perception of stakeholders in the reality of flood and in the efficiency of policies. Other parameters like social composition of the sample, natural local features of the town, etc., were not significant. As previously mentioned, the survey concerns more rural towns and their councils than major urban areas. Regarding the awareness of useful territorial tools to fight flood risks, TTRP is the most cited set of tools (54.5%). Such perception reveals the predominance of local risks.
A GIS analysis revealed that flood hazards occurred in valleys where industrial areas are concentrated  . Also, a statistical comparison of several values concerning relations between parameters led to reveal how the population feels vulnerable to flood hazards considering the distance from the valleys or the size of the community population. More precisely, there is a broad relationship between the perception of vulnerability and the kind of local target. Figure 4 shows this relationship between the value of the perception and the index summarizing the backgrounds, especially the distance from a floodplain and the size of the population of the town. There is no understanding of the consequences of catastrophic floods in industrial valleys for more rural communities, in terms of economy, employment, etc.
5. Discussion and Conclusion
Our study investigated whether environmental policy beliefs and especially concerning flood risks may make it possible to underline the resilience capabilities of a territory   . The study demonstrated the following:
・ In spite of a good overall knowledge of local issues linked to the hydrological behaviour of rivers, there is a differential sensitivity of the interviewees when it comes to hazards and risks based on proximity, spatial distance and frequency of the event.
・ The fragmented and discontinuous knowledge of scales and different issues (according to the scales) from the interviewees is one of the crucial points of the investigation.
・ Many territorial tools exist in the area and remain effective for the most part, at every level they are planned for.
・ The complexity of these tools and their different issues in terms of spatial scale levels blurs the knowledge of the interviewees and constitutes an obstacle to the process of resilience.
・ The deficiency of territorial solidarity, the whole idea of territorial solidarity (because of interdependencies between territories), but also the types of stakeholders are all elements that leave questions about culture of risk and more widely about natural representation of the territory by interviewees. Our results show weak values of the perception of risks by stake holders. In particular local stake holders do not perceive the significance of common targets. The neighborhood attributes solidarity positively affect the resilience of the territory to flood risks.
Such an example is an illustration of a classical situation in which towns and industrial areas are often located in low-lying areas near rivers, where floodplains serve as conduits twinned with infrastructures for commerce

between other regions  . The concentration of population and activities is an historical inherited situation. Consequently, within such a territory, but also in other similar ones, the collective search for strategies for sustainable development must meet questions of issues and risk management. Moreover, a control of planning and a development of information about risk importance based on finding what is considered as common heritage must be implemented in order to ensure a territorial equity. The successful implementation of such a program requires the ability to understand public needs, a degree of innovation and willingness to adopt a problem-solv- ing approach. As stated by Winter and Bromhead  , willingness is a qualitative measure of risk acceptance but risk acceptance is related to risk remediation and mitigation, especially by public policies  . One key factor is the connection across diverse local councils in order to increase local solidarity. In other situations, Hovardas and Poirazidis  have found contradictions between stakeholder beliefs and choices of public policies concerning protected area management. The aim of their study was to examine beliefs in order to understand the potential social consensus about environmental management. In our case, the Urban Area of Belfort- Montbéliard-Delle-Héricourt, UABMDH, we saw that stakeholders expect a better land management. In the same way, they also expect a better participation, whose benefits are the increase of territorial solidarity and environmental awareness, as shown by several authors   -  . Sample demographics did not influence results but environmental awareness is more or less related to the real risks: the highest potential of floods, near the fluvial floodplains, determines the strongest demand for efficient land management tools. The core of the question is the capability of solidarity in a territory where vulnerabilities are broadly geographically concentrated. As shown by Rudel  , cumulative benefits are related to the local and more global environmental awareness. As shown by Chia  and Prosser and Peters  , the resilience may be the “way through wich communities can build their capacity  . As claimed by Prosser and Peters  , the regional inquiry of local consensus increase the efficiency of risk and disaster management policies. For a resilience approach, local communities are more capable to provide a collective preventive action. In such circumstances, flood prevention may be related to local urban management that integrates global environmental management.
In fact, due to the European and French public policies, local stakeholders integrate both of these targets of land planning and territorial solidarity. In
The Urban Area of Belfort-Montbéliard-Delle-Héricourt, UABMDH, integrates land management of water basins but it also promotes broad-based civic participation in local governance. For example, councils, gathered together in the UABMDH, successfully commissioned a housing scheme on risk management. This required the acquisition of areas in the floodplain, especially near the industrial sector of Sochaux-Montbéliard, where Peugeot Company factories are located. These areas were transformed into natural reserves, Natura 2000 reserves, in order to increase drainage capacity for flooding events. As stated by Hassel (2012), risk management needs to be regarded and analysed as a system. Both approaches seem needed in order to increase the resilience of such complex territories: maintenance of multifunctionality of floodplains and participation of the stakeholders.
Our study was designed as a qualitative questionnaire transformed in quantitative data. We confirmed that the collective resilience of an area depends on stakeholders knowledge of the environmental system   and public policies and tools     . For public manager, the question of the information is essential. The resilience may be approached as a global way with and through social networks and social interactions    . Resilience to disaster may be conferred from any level in a geographical community   -  . Undoubtedly, social awareness and good understanding of the social networks upgrade the collective efficacy in risk management   . Walker et al.  and others   argue that participatory approach upgrade the resilience because people understand the relation between spatial levels in the functioning social and ecological systems as demonstrated     . Bristow and Healy  claim that human agency is an important factor to regional resilience. We can witness that the director of regional agency (DREAL) and the president of the Syndicat Mixte of the urban community whose territory we studied claimed that driving such a study with face-to-face interviews changed the opinion of the stakeholders, providing an increase of the awareness and the necessity of the solidarities, providing a way to resilience.
