Integrated Coastal Management

At present, the ecological environment and resources of the global coastal zones are facing great pressures. Climate change leads to sea level rise, environmental change, stressful population increases and changes in demographics, all of which affect existing coastal management systems. Therefore, all coastal countries begin to increasingly attach importance to the integrated management of coastal zones. How to better adapt to current changes in global coastal zones is a question that every coastal country should think about. From sea- and land-partitioned management to land and sea coordination and from simple coastal management to the integration of the ecological environment and society, integrated management has been planned from many perspectives and levels. It plays a role in promoting the construction of a community with a shared future for mankind.

This work assesses sea-level rise using three different models created on Free and Open-Source Software for Geographic Information System (FOSS4GIS). Based on regional projections of Special Report on Climate Change and Oceans and Cryosphere (SROCC) of the Intergovernmental Panel on Climate Change (IPCC), the models were applied to a case of study on Rio Grande do Sul coast – Brazil under different sea-level rise scenarios by the end of this century. The End Point Rate for QGIS (EPR4Q), calculates a shoreline projection using End Point Rate method. The Uncertainty Bathtub Model (uBTM), analyses the sea-level rise impact by the uncertainty of sea-level projec-tions and vertical error of the Digital Elevation/Terrain Model (DEM/DTM). The Bruun Rule for Google Earth Engine Model (BRGM) predicts the shoreline position with sea-level rise, using topographic and bathymetric data from Unmanned Aerial Vehicles (UAV) and Coastal Modelling System (SMC – Brazil), respectively. The results indicated a maximum shoreline retreat for 2100 of -502 m and -1727 m using EPR4Q and BRGM, correspondingly. The uBTM using the land-use of Mapbiomas showed a maximum of 44.57 km2 of urban area impacted by the sea-level flood. This research highlights the possibility of performing coastal management analysis in GIS environ-ment using non-commercial software.

In Colombia, in order to meet the challenges of coastal marine management and responding to international commitments, it was adopted in 2000 the “National Environmental Policy for the Sustainable Development of Ocean Spaces and Coastal and Insular Zones of Colombia - PNAOCI ”, which has an ecosystem approach and as a conceptual framework, the integrated management of coastal zones -MIZC (or integrated coastal management - MCI / integrated coastal management - GCI), seeking to balance environmental protection and economic development, to contribute to the Physical ordering of the territory (Territorial Ordering), from the environmental ordering. For this, criteria were defined to guide the definition of the coastal zone in the country and spatial units (Coastal Environmental Units – UACs, acronym in Spanish) were delimited, as continuous geographical areas, involving land and sea space, with clearly defined ecosystems, which they require a unified visualization and management that brings together local and subregional territorial entities; in addition to consolidating over 20 years, a conceptual, political, regulatory, technical and operational support. In the legal context, as of Law 1450 of 2011, the generation of normative support regarding the UACs and the Plans for the management and integrated management of coastal environmental units (POMIUAC, acronym in Spanish) was promoted, as a planning instrument (Decree 1120 of 2013, compiled in Decree 1076 of 2015); Likewise, based on practical cases, a methodological framework was built embodied in a technical guide for the preparation of the POMIUAC, adopted by Resolution 768 of 2017. On the other hand, although the advances in the coastal marine environmental regulation in Colombia are oriented under the MIZC, given the similarities in terms of definition, spatial scope, scope and methodology, that they have with marine spatial planning (PEM), it can be said that these processes developed in Colombia under the MIZC scheme contribute to the development of the PEM concept In the country, and in the opposite case, practical EMP exercises that are addressed could complement the advances that the country has made in this area under the policy and regulatory framework that supports it.

Extreme Precipitation Events

The world is urbanizing most rapidly in tropical to sub-temperate areas and in coastal zones. Climate change along with other global change forcings will diminish the opportunities for sustainability of cities, especially in coastal areas in low-income countries. Climate forcings include global temperature and heatwave increases that are expanding the equatorial tropical belt, sea-level rise, an increase in the frequency of the most intense tropical cyclones, both increases and decreases in freshwater inputs to coastal zones, and increasingly severe extreme precipitation events, droughts, freshwater shortages, heat waves, and wildfires. Current climate impacts are already strongly influencing natural and human systems. Because of proximity to several key warming variables such as sea-level rise and increasing frequency and intensity of heatwaves, coastal cities are a leading indicator of what may occur worldwide. Climate change alone will diminish the sustainability and resilience of coastal cities, especially in the tropical-subtropical belt, but combined with other global changes, this suite of forcings represents an existential threat, especially for coastal cities. Urbanization has coincided with orders of magnitude increases in per capita GDP, energy use and greenhouse gas emissions, which in turn has led to unprecedented demand for natural resources and degradation of natural systems and more expensive infrastructure to sustain the flows of these resources. Most resources to fuel cities are extracted from ex-urban areas far away from their point of final use. The urban transition over the last 200 years is a hallmark of the Anthropocene coinciding with large surges in use of energy, principally fossil fuels, population, consumption and economic growth, and environmental impacts such as natural system degradation and climate change. Fossil energy enabled and underwrote Anthropocene origins and fueled the dramatic expansion of modern urban systems. It will be difficult for renewable energy and other non-fossil energy sources to ramp up fast enough to fuel further urban growth and maintenance and reverse climate change all the while minimizing further environmental degradation. Given these trajectories, the future sustainability of cities and urbanization trends, especially in threatened areas like coastal zones in low-income countries in the tropical to sub-tropical belt, will likely diminish. Adaptation to climate change may be limited and challenging to implement, especially for low-income countries.

Sea Level Rise Adaptation

Sea-level rise is a direct consequence of climate change. Primarily due to ocean thermal expansion and transfer from land ice (glaciers, ice sheets) to the ocean, sea-level rise is therefore an integrated indicator of climate change. Coastal zones and communities are expected to be increasingly threatened by sea level changes, with various adverse and widespread impacts. The European Union’s Earth Observation Programmed, Copernicus, monitors our planet and its environment, for the ultimate benefit of society. This includes the monitoring of sea level changes and the provision of ancillary fields needed to assess sea-level rise coastal risks, to guide adaptation and to support related policies and directives. Copernicus is organized with a space component, including dedicated Earth Observation satellites (Sentinel missions), and services, which transform the wealth of satellite, in situ and integrated numerical model information into added-value datasets and information usable by scientists, managers and decision-makers, and the wider public. Here, an overview of the Copernicus products and services to inform on sea level rise adaptation is provided. Perspectives from Copernicus services on future evolutions to better inform on coastal sea level rise, associated risks, and support adaptation are also discussed.

The Face

<p>The concept of tipping points has received much attention in research on climate change. In the biophysical realm, climate tipping points describe critical thresholds at which large-scale elements of the Earth switch to a qualitatively different state; and ecological tipping points describe thresholds separating distinct dynamic regimes of ecosystems. The tipping point metaphor is also used to indicate transformative change in adaptation and mitigation strategies. However, there remains an underexplored field: climate change induced socio-economic tipping points (SETPs). We define an SETP as: a climate change induced, abrupt change of a socio-economic system, into a new, fundamentally different state. We make a distinction between SETPs in terms of transformational response to climate change and SETPs in terms of socio-economic impacts.</p><p>SETPs are points where a gradual change in climatic conditions causes an abrupt, fundamental reconfiguration of the socio-economic system. Through a stakeholder consultation, we identified 22 candidate SETP examples with policy relevance for Europe. Three of these were investigated in more detail, with special attention for their tipping point characteristics (stable states at both sides of a critical threshold, abrupt transition between those states, and the mechanism explaining the non-linear and abrupt behaviour).</p><p>The first example is the collapse of winter sports tourism in low-altitude ski resorts. In the face of climate change, this may occur abrupt, cause a fundamental reconfiguration of the local and regional economy, and is very hard to reverse. In some cases, it could be possible to achieve a fundamental shift towards summer tourism.</p><p>The second example is the farmland abandonment in Southern Europe. Large parts of Spain have already seen widespread farmland abandonment and associated migration. Increasing heat and drought may worsen the conditions, with considerable social, and to a lesser extent, economic consequences. On the local scale, this manifests itself as a clear SETP: a lively agricultural area suddenly tips to the ‘Spanish Lapland’: deserted farms, villages with ageing population, little economic activity and underdeveloped infrastructure and facilities.</p><p>The third example is sea-level rise induced reconfiguration of coastal zones. In the face of accelerating sea level rise (SLR), threatened communities may retreat from vulnerable coastal zones. This may be caused by migration (voluntary human mobility), displacement (involuntary movement following a disaster) or relocation (retreat managed by the government). The SETP of retreat from a certain area is usually triggered by a flood event. However, also the adaptation to increasing flood risk may be so transformative, that it can be considered a structural configuration of the system. This is currently seen in The Netherlands, where studies on extreme SLR have triggered a debate in which very transformative strategies are proposed, such as: constructing a dike in front of the entire coast, retreat from areas with economic stagnation and population decline, or elevating all new buildings above sea level.</p><p>A key insight is that the rate of climate change may exceed the capacity of society to adapt in the traditional way, triggering a shift towards fundamentally different policies and a reconfiguration of the socio-economic system.</p>

The Impact

Purpose Coastal flooding has disastrous consequences on people, infrastructure, properties and the environment. Increasing flood risk as a result of global climate change is a significant concern both within the UK and globally. To counter any potential increase in future flooding, a range of potential management options are being considered. This study aims to explore future coastal management practice for flood alleviation, incorporating the influence of climate change. Design/methodology/approach The Taf estuary in South West Wales, a macro-tidal estuary which has a history of coastal flooding, was chosen as the case study in this paper to investigate the impact of coastal management interventions such as construction of hard defences, managed realignment or altering land use of affiliated ecosystems such as salt marshes on the complex hydrodynamics and hence flooding of the surrounding areas of the estuary. The study was carried out using a numerical hydrodynamic model of the Taf estuary, developed using the process-based Delft3D modelling software. Findings The role of the selected management interventions on coastal flooding was investigated using an extreme storm condition, both with and without the impact of future sea level rise. The results highlight the scale of the effect of sea level rise, with the selected management interventions revealing that minimising the increase in flooding in future requires careful consideration of the available options. Originality/value This paper explores the highlighted role of coastal management practice in future with the influence of climate change to study how effective alternative methods can be for flood alleviation.

And Sea Level

The Earth’s climate is changing; ice sheets and glaciers are melting and coastal hazards and sea level are rising in response. With a total population of over 300 million people situated on coasts, including 20 of the planet’s 33 megacities (over 10 million people), low-lying coastal areas represent one of the most vulnerable areas to the impacts of climate change. Many of the largest cities along the Atlantic coast of the U.S. are already experiencing frequent high tide flooding, and these events will increase in frequency, depth, duration and extent as sea levels continue to rise at an accelerating rate throughout the 21st century and beyond. Cities in southeast Asia and islands in the Indo-Pacific and Caribbean are also suffering the effects of extreme weather events combined with other factors that increase coastal risk. While short-term extreme events such as hurricanes, El Niños and severe storms come and go and will be more damaging in the short term, sea-level rise is a long-term permanent change of state. However, the effects of sea-level rise are compounded with other hazards, such as increased wave action or a loss of ecosystems. As sea-level rise could lead to the displacement of hundreds of millions of people, this may be one of the greatest challenges that human civilization has ever faced, with associated inundation of major cities, loss of coastal infrastructure, increased saltwater intrusion and damage to coastal aquifers among many other global impacts, as well as geopolitical and legal implications. While there are several short-term responses or adaptation options, we need to begin to think longer term for both public infrastructure and private development. This article provides an overview of the status on adaptation to climate change in coastal zones.
