Impacts Of Climate Change

The main drivers of coastal morphology evolution related to climate change are wave characteristics, storm frequency/intensity and watershed runoff. Estuaries and deltaic plains, strongly affected by the sea-level change, are highly vulnerable to future climate change impacts. Karasu Beach, located in the southwestern Black Sea, Turkey, is impacted by the Sakarya River plume. River discharge and energetic wind and wave climate are among the major physical processes that control the sediment transport pattern along the shoreline. Due to the decrease of sediment runoff to the coast related to the construction reservoirs and a harbor, significant erosion occurred, with a 7.5 m/year retreat of the coastal line. The erosion problem threatens the coastal area as well as the deep spot.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/DfYQlbOXEh8

Impacts Of Climate Change

The impacts of climate change, including sea level and wave climate changes, may increase future erosion risks. Thus, it is important to improve knowledge of the dominant physical processes controlling medium- to long-term shoreline evolution, as well as the performance of beach evolution models reproducing past observations and predicting future changes. Empirical equilibrium beach change models may be an optimal choice at these spatial and temporal scales. Here, morphological changes at Vougot Beach (Brittany, France) are analyzed by evaluating the cross-shore evolution of contour elevations (-1 to 6m) along six intertidal beach profiles using observations and an equilibrium beach change model, and then three methods for estimating the impacts of climate change are applied and compared.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/p70KuzjR1kU

A Site

In this paper we examine the evidence for detectable climate change impacts on shoreline evolution. In a sequentially linked set of models, climate change scenarios are taken from atmospheric climate models and used to generate time slices of deepwater wave climate, nearshore wave climate and shoreline evolution. The models used are simple, containing the key physical processes only. Results are based on a hypothetical case which has some similarities to a site on the south coast of the UK. Output from the model is analysed using a robust statistical methodology to determine the evidence for statistically significant differences between beach behaviour under current conditions and several future scenarios. Statistically significant differences vary with season and also with the combination of climate model outputs used for input. Summers are the only season for which all models showed significant changes, corresponding to an increase in the net eastward littoral transport.

Impacts Of Climate Change

AbstractClimate change threatens biodiversity directly by influencing biophysical variables that drive species’ geographic distributions and indirectly through socio-economic changes that influence land use patterns, driven by global consumption, production and climate. To date, no detailed analyses have been produced that assess the relative importance of, or interaction between, these direct and indirect climate change impacts on biodiversity at large scales. Here, we apply a new integrated modelling framework to quantify the relative influence of biophysical and socio-economically mediated impacts on avian species in Vietnam and Australia and we find that socio-economically mediated impacts on suitable ranges are largely outweighed by biophysical impacts. However, by translating economic futures and shocks into spatially explicit predictions of biodiversity change, we now have the power to analyse in a consistent way outcomes for nature and people of any change to policy, regulation, trading conditions or consumption trend at any scale from sub-national to global.

Insular Ecosystems

Abstract Despite their high vulnerability, insular ecosystems have been largely ignored in climate change assessments, and when they are investigated, studies tend to focus on exposure to threats instead of vulnerability. The present study examines climate change vulnerability of islands, focusing on endemic mammals and by 2050 (RCPs 6.0 and 8.5), using trait-based and quantitative-vulnerability frameworks that take into account exposure, sensitivity, and adaptive capacity. Our results suggest that all islands and archipelagos show a certain level of vulnerability to future climate change, that is typically more important in Pacific Ocean ones. Among the drivers of vulnerability to climate change, exposure was rarely the main one and did not explain the pattern of vulnerability. In addition, endemic mammals with long generation lengths and high dietary specializations are predicted to be the most vulnerable to climate change. Our findings highlight the importance of exploring islands vulnerability to identify the highest climate change impacts and to avoid the extinction of unique biodiversity.

Abstract This book is a collection of 77 expert opinions arranged in three sections. Section 1 on "Climate" sets the scene, including predictions of future climate change, how climate change affects ecosystems, and how to model projections of the spatial distribution of ticks and tick-borne infections under different climate change scenarios. Section 2 on "Ticks" focuses on ticks (although tick-borne pathogens creep in) and whether or not changes in climate affect the tick biosphere, from physiology to ecology. Section 3 on "Disease" focuses on the tick-host-pathogen biosphere, ranging from the triangle of tick-host-pathogen molecular interactions to disease ecology in various regions and ecosystems of the world. Each of these three sections ends with a synopsis that aims to give a brief overview of all the expert opinions within the section. The book concludes with Section 4 (Final Synopsis and Future Predictions). This synopsis attempts to summarize evidence provided by the experts of tangible impacts of climate change on ticks and tick-borne infections. In constructing their expert opinions, contributors give their views on what the future might hold. The final synopsis provides a snapshot of their expert thoughts on the future.

New research is drawing attention to the potential for climate change to generate cascading impacts and implications across linked human-environment systems, requiring closer accounting of these interactions to anticipate the emergence of surprises and feedbacks. However, there is little practical guidance for those interested in characterising, identifying or assessing cascades, and few empirical examples. In this paper, we elaborate a systems-based methodology to identify and evaluate cascading climate change impacts and implications. We illustrate its application using the case of a participatory process with urban infrastructure managers, facing the legacy effects of damaging earthquakes and the prospect of future climate change. The results show the proposed approach and visualisation of cascades as causal diagrams provides a robust and flexible analytical framework. The use of systems thinking, visual aids, interactive discussion and expert elicitation generated valuable information about potential cascades, their interactions across domains of interest, and the implications for management. The process can provide a basis for further empirical application and advance methodological and conceptual development. Specifically, the systems methodology: • Identifies interdependencies and interconnections which may serve as transmission pathways for climate-related impacts; • Enhanced stakeholders’ understanding of multiple causes and effects of climate change; and • Produced a useful visual aid for stakeholders to explore cascading impacts and implications, and opportunities for intervention.

Este artigo descreve a experiência da coalizão Adapta Sertão na experimentação e disseminação de sistemas produtivos que possam tornar o agricultor familiar do Semiárido mais resiliente aos impactos da variação climática atual e da mudança do clima no futuro. Durante as experimentações, a coalizão teve que enfrentar várias barreiras ligadas à falta de integração entre políticas públicas existentes e projetos pilotos em comunidades locais. Hoje, a adaptação à mudança do clima não está sendo considerada na implementação de obras hídricas de pequeno e médio porte, que são de grande importância porque, geralmente, conseguem beneficiar as faixas de população mais pobres e mais suscetíveis aos impactos climáticos. As experiências mostram que é preciso desenvolver, com urgência, políticas públicas inovadoras que consigam integrar o acesso à água com a disseminação de tecnologias de adaptação e de sistemas produtivos mais resilientes à seca.  Palavras - chave: medidas de adaptação, agricultura familiar, semiárido, tecnologia.  The experience of the Adapta Sertão Coalition in Disseminating Climate Change Adaptation Technologies and Strategies for Family Farmers in Semi Arid Brazil  ABSTRACTThis paper describes the experience of the Adapta Sertão coalition in testing and experimenting production systems that have the potential to make small farmers of semi-arid Brazil more resilient to current and future climate change impacts. During the different testing, the coalition had to overcome several barriers linked to a lack of integration between current public policies. For example, today climate change is not considered in the design and implementation of small and medium hydraulic infrastructures. This limits the benefits to the target groups (small farmers) that are more likely to be affected by climate change. The experiences show that it is urgent and necessary to develop public policies to better integrate access to water, dissemination of climate resilient technologies and implementation of production systems more adequate to the semi arid conditions.  Keywords: adaptation measures, family farming, semi-arid, technology.
