Abstract. Daily tidal water level variations are a key control on shore ecology, on access to marine environments via ports, jetties, and wharves, on drainage links between the ocean and coastal hydrosystems such as lagoons and estuaries, and on the duration and frequency of opportunities to access the intertidal zone for recreation and food harvesting purposes. Further, high perigean spring tides interact with extreme weather events to produce significant coastal inundations in low-lying coastal settlements such as on deltas. Thus an understanding of daily through monthly tidal envelope characteristics is fundamental for resilient coastal management and development practices. For decades, scientists have described and compared daily tidal forms around the world's coasts based on the four main tidal amplitudes. Our paper builds on this “daily” method by adjusting the constituent analysis to distinguish between the different monthly types of tidal envelopes occurring in the semidiurnal coastal waters around New Zealand. Analyses of tidal records from 27 stations are used alongside data from the FES2014 tide model in order to find the key characteristics and constituent ratios of tides that can be used to classify monthly tidal envelopes. The resulting monthly tidal envelope classification approach described (E) is simple, complementary to the successful and much used daily tidal form factor (F), and of use for coastal flooding and maritime operation management and planning applications in areas with semidiurnal regimes.

Abstract. In a world of increasing coastal inundation hazards, an understanding of daily through to monthly tidal envelope characteristics is fundamental to resilient coastal management and development practices. For decades, scientists have described and compared daily tidal forms around the world’s coasts based on the four main tidal amplitudes. Our paper builds on this daily method by adjusting the constituent analysis to distinguish the different monthly types of tidal envelope occurring in the semi-diurnal coastal waters around Aotearoa New Zealand. Analyses of tidal records from 23 stations are used, alongside data from the FES2014 tide model database and theoretical experiments, in order to find the key characteristics and constituent ratios of tides that can be used to classify monthly tidal envelopes. The resulting monthly tidal envelope classification approach described (FMS) is simple, complementary to the successful and much used daily tidal form factor (F), and of use for coastal flooding, climate change and maritime operation management and planning applications in semi-diurnal regimes.

Ocean acidification (OA) generally refers to the ongoing decrease in ocean pH. Ocean acidification is caused primarily by the oceanic uptake of excess carbon dioxide (CO2) from the atmosphere. Other impacts related to climate change (increased sea level rise, coastal flooding and extreme weather events) often receive more attention than OA, but the acidification of the Earth’s oceans is well documented and is a major concern for the marine science community. This publication is the first in a series that addresses ocean acidification in Florida. It specifically explains the changes that are occurring to the chemistry of our coastal and oceanic waters because of elevated carbon dioxide levels. Additional publications address potential environmental, economic, and social implications for Florida.

Ecological Transition

The coast of the province of Cádiz (south-western Spain) is a high ecological value area and great socioeconomic importance: coastal municipalities account more than 60% of the province’s population and support key development sectors (tourism, shipbuilding, maritime traffic, etc.). It is also a fragile, dynamic and complex system affected by many human pressures. Climate change is also threatening coastal areas. Its evidences are becoming increasingly clear in the province: intensification of coastal erosion processes, sea level rise or an increase in the frequency and intensity of extreme weather events. The Provincial Government of Cádiz has developed, with support of the Ministry for the Ecological Transition through the Biodiversity Foundation, a Coastal Management Programme with the aim to face climate challenge by integrating adaptation in coastal municipalities’ planning and management. Through a participatory process, 57 measures to be implemented in the short/medium term have been defined targeting the field of information and knowledge, education and communication, training, cooperation and assistance to municipalities and resources. In a complementary way, Covenant for the Sustainability of the Coast has been launched, as a tool for communication, coordination and inter-administrative cooperation in the provincial coastal area. Support material and capacity building actions for local entities’ representative have been developed. The Programme also includes actions to support environmental education on climate change on the coast. Keywords: Adaptation, integrated coastal management, climate change, municipality, Cádiz.

Abstract In this study an attempt is made to highlight important variables shaping the current bioclimatic niche of a number of mite species associated with the infestation of stored products by employing a species distribution modeling (SDM) approach. Using the ENVIREM dataset of bioclimatic variables, performance of the most robust models was mostly influenced by: 1) indices based on potential evapotranspiration, which characterize ambient energy and are mostly correlated with temperature variables, moisture regimes, and 2) strong fluctuations in temperature reflecting the severity of climate and/or extreme weather events. Although the considered mite species occupy man-made ecosystems, they remain more or less affected by the surrounding bioclimatic environment and therefore could be subjected to contemporary climate change. In this respect investigations are needed to see how this will affect future management targets concerning the safety of food storages.

General Concern

Most scenarios indicate that people in developing countries are more vulnerable and less capable of adapting to climate change. Since our public understanding of risk toward climate change in developing countries is limited, this article presents results from Costa Rica and Nicaragua, two countries which are socio-economically distinct, but which are expected to suffer similar extreme weather events. From October of 2008 until May 2010, a total of 1,047 respondents were surveyed in cities of both countries. The main results indicate that climate change is a widely known concept but other notions such as “carbon footprint” are foreign to most respondents. Despite the general concern with its negative consequences, respondents’ foremost concern is linked to their socioeconomic situation, and how it will be impacted by climate change in such aspects as poverty and social security. The results presented here contribute to advance national and international policies aiming to support mitigation or adaptation strategies in developing countries.
