“…Although managed retreat is always controversial, especially in heavily populated areas, a few examples in the UK have been successfully implemented after long deliberation processes (Myatt, 2003). These have been able to overcome some difficult pitfalls related to institutional arrangements, lack of technical knowledge and resources, and lack of sufficient financial compensation (Ledoux et al 2005). …”

III AgraïmentsEstem a primers dels 2008. Abans de tancar aquesta etapa i proposar-me nous reptes no puc deixar de mirar enrera i recordar l'immens suport que he rebut de tantíssimes persones. Entre tots heu contribuit a donar forma a aquest projecte i aquestes línies volen fer-vos arribar el meu profund agraïment i la gran satisfacció em queda de què m'hagueu acompanyat durant aquesta llarga travessia.Començo pels meus directors. La Míriam em va iniciar en les ciències socials quan ens vam conèixer en el projecte Eurosion. Gràcies a la seva presència des del bon principi i al seu paper més enllà de lo professional, és en gran part la responsable de què hagi arribat a bon port. El David amb el seu entusiasme i les ganes d'innovar ha sigut un bon estímul.El finançament de la recerca no ha faltat mai gràcies als següents projectes i institucions:-Projecte Europeu Eurosion (2002)(2003)(2004) En aquests projectes he tingut la sort de treballar amb investigadors de diverses disciplines que han enriquit la meva capacitat integradora i m'han acostat a altres llenguatges. Entre ells, no puc deixar de citar a la petita gran familia d'Eurosion: el Jordi, l'Oriol i la Carlota. Del gran col·lectiu que fomava el MevaPlaya vull agraïr especialment les aportacions i critiques del Jose i la complicitat de l'Edu. També, han tingut un gran paper la gran colla d'enquestadors i amicsMireia, Irene, Alba, Martí, Daniela, Sílvia, Montse, Javi, Feliu, Esther-que amb tanta il·lusió es van oferir per ajudar-me a cobrir les platges en tres temporades. Em plau molt haver pogut combinar amistat i feina en diverses ocasions, com en el projecte Messina que vam realitzar conjuntament amb el Gonzalo de qui vaig aprendre sobre multicriteri. L'estudi de la percepció social requereix la disposició desinteressada de molts entrevistats i enquestat als qui vull agrair el temps que em van dedicar, la majoria d'ells amb una gran predisposició. També agrair l'ajuda de la Bet en les transcripcions i la Rosa en la realització d'algunes entrevistes.Per mi, la vessant més afectiva d'aquesta etapa ha estat fonamental i completament imprescindible. Sense dubte, el doctorat no hagués estat el mateix sense la gran companyia dels becaris de l'ICTA amb qui ens hem divertit i també recolçat durant aquest llarg procés. El balanç final és definitivament positiu. Agraeixo als veïns de la ETC-TE que m'hagin acollit como una més i, en particular a l'Alex pel suport cartogràfic.Finalment agrair als meus pares, l'Alba i els amics per ser-hi sempre. Moltes gràcies a tots! IV V AbstractCoasts are some of the most valuable ecosystems on Earth. However, not only coasts hold some of the most biodiverse and productive landscapes but at the same time they are some of the most coveted by humans. Current trends on demographic growth and urbanization indicate that in the near future the anthropic pressure in coastal areas is very likely to intensify. Climate change adds new risks and uncertainties to the dynamics of coastal systems and their management.The management of most Medit...

“…Higher sea water levels will increase the chance of embankments being overtopped and will add to debates over whether sea defences should be maintained to protect what is, at least from an agricultural point of view, less economically valuable land (e.g. Ledoux et al, 2005). The ultimate fate of the marshes may be the replacement of freshwater wetlands with saline ecosystems, a trend forecast for other coastal areas (e.g.…”

Hydrological impacts of climate change upon the Elmley Marshes, southeast England, are simulated using a coupled hydrological/hydraulic model developed using MIKE SHE/MIKE 11 and calibrated to contemporary conditions. Predicted changes in precipitation, temperature, radiation and wind speed from the UK Climate Impacts Programme associated with four emissions scenarios for the 2050s are used to modify precipitation and potential evapotranspiration data. For each emissions scenario two sets of potential evapotranspiration data are derived, one using changes in temperature (PET temp ), the other incorporating changes in temperature, radiation and wind speed (PET trws ). Results indicate drier conditions through the progressively higher emissions scenarios when compared to contemporary conditions. Changes are particularly pronounced when using PET trws . Summer water tables are lower (PET temp 0.01-0.08 m; PET trws 0.07-0.27 m) and the duration of high winter water tables is reduced. Although water tables still intercept the surface in winter when using PET temp , this ceases when PET trws is employed. Summer ditch water levels for the PET temp scenarios are lower (0.01-0.21 m) and in dry winters they do not reach mean field level. Under the PET trws scenarios summer and winter ditch water levels are lower by on average 0.21 m and 0.30 m respectively. Levels never reach the elevation of the marsh surface. Lower groundwater and ditch water levels result in declines in the magnitude and duration of surface inundation which is virtually eliminated with the PET trws scenarios. Hydrological changes can be expected to have ecological impacts which may include the loss of some grassland species adapted to periods of high water table. Reductions in the extent of surface water in spring, especially for the PET trws scenarios, are likely to reduce suitability for wading birds including lapwing (Vanellus vanellus) and redshank (Tringa totanus) for which the marshes are internationally renowned.

Considering the scale and importance of managed realignment in national and regional strategies of climate change adaptation, habitat creation and flood risk management, gaining wider public acceptance is fundamental.…”
