“…Management of sea-level rise (or flooding) commonly includes climate-targeted engineering options such as building physical structures, adding sand or shingle (beach nourishment; Berry et al 2013), or constructing man-made living reefs (e.g., oyster beds; Lin and Petersen 2013). Engineered structures are highly debated as ecological management tools because, while they can control inundation and help retain riparian or coastal vegetation, they prevent landward migration of tidal vegetation (Hulme 2005, Greenwood et al 2016.…”

Changes in Earth's climate are accelerating, prompting increasing calls to ensure that investments in ecological restoration and nature conservation accommodate such changes. To acknowledge this need, we propose the term “ecological renovation” to describe ecological management and nature conservation actions that actively allow for environmental change. To evaluate and progress the development of ecological renovation and related intervention options in a climate change context, we reviewed the literature and established a typology of options that have been proposed. We explored how these options address emerging principles underpinning climate‐adapted conservation goals and whether the balance of approaches reflected in our typology is likely to be sufficient given expected rapid rates of climate change. Our typology recognizes a matrix of 23 intervention option types arranged on the basis of underpinning ecological mechanisms (“ameliorate changing conditions” or “build adaptive capacity”) on one axis, and the nature of the tools used to manipulate them (“low regrets” or “climate targeted”) on the other. Despite a burgeoning literature since 2008, we found that the majority of effort has consistently focused on low‐regrets adaptation approaches that aim to build adaptive capacity. This is in many ways desirable, but a paradigm shift enabling greater attention to climate‐targeted approaches is likely to be needed as climate change accelerates. When assessed against five emerging principles for setting nature conservation goals in a changing climate, only one option type could deliver to all five, and we identified a conflict between climate‐targeted options and “wildness” values that calls for deeper evaluation. Importantly, much of the inference in the 473 reviewed studies was drawn from ecological reasoning and modeling, with only 16% offering new empirical evidence. We also noted significant biases toward North America and Europe, forest ecosystems, trees, and vertebrates. To address these limitations and help shift the paradigm toward humans as “renovators” rather than “restorers” of a prior world, we propose that ecological researchers contribute by (1) informing societal discourse toward adapting nature conservation goals to climate change, (2) adjusting and upscaling conservation planning to accommodate this suite of climate‐adapted goals, and (3) reconceptualizing experimental approaches to increase empirical evidence and expedite innovation of tools to address change.

“…Whether beach nourishments are applied in coastal areas, is dependent on numerous factors and circumstances. First the desired adaptation strategy: coastal protection, accommodate, (re)claiming land from the sea, limited intervention (“passive retreat”), non-intervention, managed retreat, or ecosystem conservation 31 . Only if a coastal manager opts for coastal protection – the most common adaptation option – and has the knowledge and means to execute this strategy, nourishments are one of the possibilities.…”

Whether a coastal area is suitable for beach nourishments and can induce a growth in fresh groundwater resources depends on the appropriateness of the intended site for beach nourishments, and the attainable growth in fresh groundwater resources. In this study we presume that all eroding sandy beaches are suitable for large beach nourishments, and focus on the impact of these nourishments on fresh groundwater in various coastal settings. The growth in fresh groundwater resources – as a consequence of the construction of a beach nourishment – was quantified with 2-D variable-density groundwater models, for a global range in geological parameters and hydrological processes. Our simulation results suggest that large beach nourishments will likely lead to a (temporary) increase of fresh groundwater resources in most settings. However, for a substantial growth in fresh groundwater, the coastal site should receive sufficient groundwater recharge, consist of sediment with a low to medium hydraulic conductivity, and be subject to a limited number of land-surface inundations. Our global analysis shows that 17% of shorelines may consist of erosive sandy beaches, and of these sites 50% have a high potential suitability. This shows a considerable potential worldwide to combine coastal protection with an increase in fresh groundwater resources.

“…Coastal dunes protection should recognise the inter-connectedness of dune successional habitats, and the supply of sand which maintains dunes in healthy condition, and should aim to protect dunes from further encroachment by development pressures (Barbier et al,2011;Liquete et al, 2013). Maintaining natural dune zonation has been identified as critical in preserving the integrity and biodiversity value of dune systems, but is also essential to provide many regulating ecosystem services, such as coastal defence (van der Meulen et al, 2008;Berry et al, 2013).…”
