Abstract

The use of geotextile sand containers (GSCs) in shoreline protection systems has moderately grown since the first applications in the 1970s and increasingly used as an alternative to natural stone, slag, and concrete. Due to their economical, technical and ecological advantages, the use of geotextiles and geocomposites for filter and drainage functions is increasing worldwide and has a 40 year history already. For coastal protection measures, nonwovens are proven to have long-term resistance against ultraviolet radiation and saltwater. High elongation behavior provides superior properties during loading in coastal protection means, which is determined as being the biggest risk for damaging geotextiles. Such applications require certain functional characteristics in the geotextiles, besides their basic properties, which are required to be engineered by the judicious optimization of the needlepunching process. In this study, the effect of the process parameters including punch density and depth of needle penetration has been investigated on the mechanical (tensile strengths in the machine and cross-machine directions) properties of needlepunched nonwoven geotextiles. These process parameters are then empirically related to the fabric properties by using a multiple regression technique.

Abstract

Purpose

Non‐marketable natural coastal resources such as beaches, sand‐dune systems and cliff sides have an economic value deriving not least from the various services which they provide as well as the human demand for consuming some of these services. Coastal defence projects designed to protect the coast against erosion and flooding by the sea have often caused irreversible degradation to coastal natural resources. The main aim of this article is to investigate whether the joint use of cost‐benefit analysis and environmental resource valuation techniques can give any insights toward the sustainable use of the coast. Design/methodology/approach – This paper employs cost‐benefit analysis (CBA) in order to assess the justifiability of carrying out coast protection works in a particular location. This paper also uses contingent valuation methodology (CVM) to estimate the economic values of non‐marketable coastal environmental services. In particular, this paper employs willingness to pay (WTP) technique and try to elicit satisfaction values from beach users by conducting an on‐site questionnaire survey. Findings – his paper argues that there are many advantages in approaching shoreline protection project appraisal both from an environmental as well as an economics point of view. However, when conducting a cost‐benefit analysis the monetary value of environment elicited by contingent valuation techniques has very limited use in it self. It can set the financial budget within which likely coast protection options should be considered but it cannot determine which option is more sustainable. What the decision‐maker needs is to give real meaning to this value by translating it into people's specific preferences and behavioural characteristics. The next step should be setting out pragmatic project characteristics to accommodate the above preferences. Practical implications – Knowledge‐based planning and scheduling as well as informed coastal protection decisions is central to achieving sustainability in the coastal zone. Prior to managing a coastal area, the baseline information needed is the economic value of services that the coastal location in question provides. Originality/value – Generally speaking, the economic value of non‐marketable natural coastal resources such as beaches is closely associated with the way in which society perceives the environment. Both use and non‐use values that are placed upon the environment by individuals have an anthropocentric basis. In this respect, it could be argued that these values often reflect multiple coastal zone uses, conflicts of human interests, levels of environmental education, environmental awareness and environmental appreciation.

Abstract

Purpose

Over the past century, the rate of sea level rise (SLR) has increased more than twice the average historical rate and the US Environmental Protection Agency estimates that by 2100 the sea level will increase nearly two feet in many coastal areas. Property owners and municipalities typically respond to SLR by constructing seawalls and similar structures to protect shoreline property (a practice known as “armoring”). The degree to which SLR and armoring threaten key coastal habitats has not been well studied, however. This study, aims to develop an inundation model on behalf of Stratus Consulting to examine anticipated habitat changes in coastal Ocean County, New Jersey.

Design/methodology/approach

The model used a geographical information system to map predicted changes in coastal habitats under two alternative SLR scenarios and six different shoreline armoring scenarios. The paper then used information from local experts and the scientific literature to predict changes in the relative abundances of fish and bird species under the different scenarios.

Findings

Under all scenarios, the model predicted substantial declines in the areal extent of Spartina marshes and in the annual production of finfish and shrimp. Declines in these marsh‐dependent species would have significant impacts on commercial and recreational fisheries. The study also predicted substantial declines in bird species such as songbirds and dabbling ducks.

Originality/value

The results of the study can help local stakeholders and decision‐makers plan responses to SLR. Conventional armoring responses could result in substantial and irreversible losses of coastal habitats and the species dependent on these habitats.

Abstract

Purpose

Climate change is a global threat to social, economic, and environmental sustainability. In an increasingly urbanized world, homeowners play an important role in climate adaptation and environmental sustainability through decisions to landscape and manage their residential properties.

Methodology/approach

In this chapter, we review the potential impacts of climate change on environmental sustainability in urban ecosystems and highlight the role of urban and suburban residents in conserving biodiversity. We focus extensively on the interactions of homeowners and residential landscapes in urban coastal and desert environments.

Practical implications

Understanding how human-environment interactions are linked with a changing climate is especially relevant for coastal and desert cities in the United States, which are already experiencing visible impacts of climate change. In fact, many homeowners are already making decisions in response to environmental change, and these decisions will ultimately shape the future structure, function and sustainability of these critically important ecosystems.

Social implications

Considering the close relationship between biodiversity and the health and well-being of human societies, understanding how climate change and other social motivations affect the landscaping decisions of urban residents will be critical for predicting and enhancing sustainability in these social-ecological systems.

Abstract

The public’s traditional right to enjoy the shore was unchallenged until the twentieth century. The population shift to coastal areas and the subsequent development of coastal lands by private parties has brought both public and private interests into bitter conflict over this prime real estate. The US Federal Government has encouraged public access but has left its implementation to the states. In turn, lack of funds and staff has forced the states to rely heavily on individuals and citizen action groups to find, open, maintain and publicize access. This bibliography identifies sources that can help interested individuals and action groups increase public coastal access while preserving the rights of private property owners.

Abstract

This chapter highlights ecosystem-based adaptation in coastal Bangladesh aimed at securing climate and disaster-resilient environment for safer life and livelihood for vulnerable communities in the face of changing climate. Development intervention based on the opportunities offered by the nature and adaptation management plan from the perspective of vulnerability analysis can make a substantive difference in enhancing resilience. Engagement of broad-based stakeholders at vertical and horizontal levels in building adaptive capacity can be linked through both at the policy and institutional levels as well as at ecosystem levels for effective results. Innovation in convergence of disaster risk reduction and adaptation through fish, fruit, and forest as a part of livelihood integrated into the coastal afforestation ensure better livelihood in a safer coastal habitats. Such forest-based adaptive livelihood and carbon sequestration help land development that is promising to offset the sea level rise due to higher rate of siltation. Climate resilient habitat is another innovative initiative that protects the households, and their livelihood is protected by eco-engineering structures and green defense to make it safer from cyclone and tidal surge.

Abstract

Purpose

Climate change poses diverse, often fundamental, challenges to livelihoods of island peoples. The purpose of this study is to demonstrate that these challenges must be better understood before effective and sustainable adaptation is possible.

Design/methodology/approach

Understanding past livelihood impacts from climate change can help design and operationalize future interventions. In addition, globalization has had uneven effects on island countries/jurisdictions, producing situations especially in archipelagoes where there are significant differences between core and peripheral communities. This approach overcomes the problems that have characterized many recent interventions for climate-change adaptation in island contexts which have resulted in uneven and at best only marginal livelihood improvements in preparedness for future climate change.

Findings

Island contexts have a range of unique vulnerability and resilience characteristics that help explain recent and proposed responses to climate change. These include the sensitivity of coastal fringes to climate-environmental changes: and in island societies, the comparatively high degrees of social coherence, closeness to nature and spirituality that are uncommon in western contexts.

Research limitations/implications

Enhanced understanding of island environmental and social contexts, as well as insights from past climate impacts and peripherality, all contribute to more effective and sustainable future interventions for adaptation.

Originality/value

The need for more effective and sustainable adaptation in island contexts is becoming ever more exigent as the pace of twenty-first-century climate change increases.

Abstract

Purpose

The purpose of this paper is to present an overview of the vulnerability of Florida’s coastal destinations to climate change and the costs of the adaptation measures required to cope with the impacts of climate change in a range of current and future scenarios.

Design/methodology/approach

The paper illustrates a range of current and projected climate change scenarios in Florida, the challenges the state is already experiencing in dealing with the impacts of climate change and some of the measures adopted to date in three particularly vulnerable coastal destinations, namely Fort Lauderdale, Miami Beach and Sarasota.

Findings

Although tourism is the number one industry in Florida, the state holds a particularly vulnerable position with respect to climate change. The vacuum of political will to address these issues at the state level is thus of particular concern given the vulnerable position of Florida’s coastal areas. With nearly 10 percent of its land area lying at less than one meter above the present sea level, adaptation is especially urgent in Florida. The local government of Florida’s cities such as Fort Lauderdale, Miami Beach and Sarasota are not willing to surrender to sea level rise (SLR). However, without a strong political will to address climate change at the state and federal levels, the costs of adapting to an escalating SLR are becoming progressively unsustainable.

Originality/value

This illustrative case study paper provides a contemporary synthesis of the implications for Florida’s coastal tourism destinations of rising sea levels and those adaptation strategies deemed appropriate in the search for their longer-term sustainability.

Abstract

Purpose

Mangrove forests are one of the most bio-diverse and productive wetland environments on earth. However, these unique tropical forest environments that occupy coastal areas are among the most threatened habitats globally. These threats include logging, conversion of land for agriculture and mariculture and degradation due to pollution over the past 50 years. The large population of resilient mangroves occupying the Turneffe Atoll area in Belize faces growing anthropogenic threats such as permanent clearing of land for housing, infrastructural development and pollution and natural factors (climate change). Given the few formal studies done to evaluate mangrove resilience at Turneffe Atoll, the purpose of this study was to evaluate mangrove resilience and nursery functions in the Turneffe Atoll Marine Reserve (TAMR).

Design/methodology/approach

Mangrove fish abundance and forest structure was assessed by means of a visual census and the point-centred quarter method (PCQM) for 11 sites that span across conservation and general use zones.

Findings

This study found that the more resilient mangroves (lower vulnerability ranks, higher standing biomass and higher fish biomass and abundance) exist in general use zones and warrant the need for improved mangrove conservation measures for these areas by Turneffe Atoll Sustainability Association (TASA).

Research limitations/implications

Limitations of the methods for data collection included accessibility within mangrove forests stands when establishing PCQM, observer bias among data collectors, sites without surrounding mangroves were not captured to serve as a true control group and poor visibility underwater affected the estimation of fish species and size. The timeline for this research was only three months based on available funding, and no follow-up study was done to make a true comparison.

Originality/value

The findings of this research have a guiding role in the formulation of conservation measures such as better waste management, a robust framework for mangrove management, a communication strategy to guide public awareness and long-term monitoring surveys.

Abstract

Purpose

Commercial entities have recently expressed growing interest in commercialising indigenous knowledge (IK) due to its enormous economic and intrinsic value. As this happens, custodial communities must not be disadvantaged in the process. This paper aims to understand the legal framework of the commercialisation of IK to identify the opportunities and factors impeding or affecting the commercialisation of indigenous knowledge in Kenya.

Design/methodology/approach

The study used a qualitative research approach. An extensive exploratory literature review of existing legal instruments was done to establish the progress and gaps for commercialising indigenous knowledge in Kenya.

Findings

The study shows that the legal framework of IK in Kenya is inadequate. There are no well-established frameworks and policies to protect IK in Kenya, and thus, host communities are subjected to exploitation. The diversity of tribes and communities makes it challenging to have a clear framework, mainly because IK is a devolved function. The study identifies the Protection of Traditional Knowledge and Cultural Expressions Act 2016, The National Museums and Heritage Act 2006 and the Natural Products Industry as the key milestones towards commercialisation of IK, while inadequate documentation of IK, communal ownership and inadequate legislation were identified as the main impediments to commercialisation of IK in Kenya.

Research limitations/implications

Owing to the diverse cultures and tribal communities in Kenya, the research could not access all the literature on all traditional IK in Kenya, and very few case studies have been conducted in Kenya.

Practical implications

The gaps identified in the legal framework can form a basis for legislation, policy change, actions and research needed to improve the commercialisation of IK.

Originality/value

The paper underscores the importance of balancing economic empowerment with preserving cultural integrity and protecting indigenous rights in commercialisation.
