The ecosystem services concept is a useful tool in environmental law, as it allows nature to be considered on the same plane of comparison as proposed development. However, the concept has received significant criticism, with many critics arguing that nature should be valued for its intrinsic worth. This article synthesises the ethical objections to the ecosystem services concept, distinguishing objections to the concept itself, and objections to the commodification of nature. It considers how the concept has been used in Australian environmental law to date, drawing on examples from the coastal wetland context. It concludes that most applications have not involved commodification, and have incorporated notions of intrinsic value. It concludes with some observations for future progress in this field, considering how the ecosystem services concept can be balanced with concerns for respecting the intrinsic value of nature.

Coastal wetland mapping plays an essential role in monitoring climate change, the hydrological cycle, and water resources. In this study, a novel classification framework based on the gravitational optimized multilayer perceptron classifier and extended multi-attribute profiles (EMAPs) is presented for coastal wetland mapping using Sentinel-2 multispectral instrument (MSI) imagery. In the proposed method, the morphological attribute profiles (APs) are firstly extracted using four attribute filters based on the characteristics of wetlands in each band from Sentinel-2 imagery. These APs form a set of EMAPs which comprehensively represent the irregular wetland objects in multiscale and multilevel. The EMAPs and original spectral features are then classified with a new multilayer perceptron (MLP) classifier whose parameters are optimized by a stability-constrained adaptive alpha for a gravitational search algorithm. The performance of the proposed method was investigated using Sentinel-2 MSI images of two coastal wetlands, i.e., the Jiaozhou Bay and the Yellow River Delta in Shandong province of eastern China. Comparisons with four other classifiers through visual inspection and quantitative evaluation verified the superiority of the proposed method. Furthermore, the effectiveness of different APs in EMAPs were also validated. By combining the developed EMAPs features and novel MLP classifier, complicated wetland types with high within-class variability and low between-class disparity were effectively discriminated. The superior performance of the proposed framework makes it available and preferable for the mapping of complicated coastal wetlands using Sentinel-2 data and other similar optical imagery.

English Abstract: How do societies value and interact with ecosystem services (ES) to favor their long-term conservation? Under the premise that sociocultural assessment of ES offers an expanded perspective for potential societal nature contributions, we present here the empirical results of a participative assessment of ES in the Laguna de Nuxco coastal wetland in 2019. The methodological design includes the combination of applied qualitative tools on site and quantitative methods for analysis of information. The results emphasize that the ES of the wetland support socioeconomic needs and important socio-cultural community traits, such as cultural heritage and identity as fishing communities. We identify emerging socio-ecological conflicts that promote the decrease of ES. We suggest conceptual and methodological adaptations for the participative assessment of ES on the local scaleSpanish Abstract: ¿Cómo las sociedades valoran e interactúan con los servicios ecosistémicos (SE) que les rodean para favorecer su conservación a largo plazo? Bajo la premisa que la valoración sociocultural de SE ofrece una perspectiva ampliada para potenciales contribuciones sociedad-naturaleza, presentamos aquí los resultados empíricos de una valoración participativa de SE del humedal costero Laguna de Nuxco en 2019. El diseño metodológico incluyó la combinación de herramientas cualitativas aplicadas en sitio y cuantitativas para el análisis de información. Los resultados enfatizan que los SE del humedal sustentan necesidades socioeconómicas e importantes aspectos socioculturales como patrimonio cultural e identidad como comunidades pesqueras. Identificamos conflictos socioecológicos emergentes que promueven la disminución de SE. Sugerimos adecuaciones conceptuales y metodológicas para la valoración participativa de SE en la escala local.French Abstract: Comment les sociétés valorisent-elles et interagissent-elles avec les services écosystémiques (SE) pour favoriser leur conservation à long terme? Le principe de l’évaluation socioculturelle des SE off re une perspective élargie des contributions potentielles société-nature, et est utilisé pour présenter les résultats empiriques d’une évaluation participative des SE réalisée en 2019 dans la zone humide côtière de Laguna de Nuxco, au Mexique. La méthodologie comprenait la combinaison d’outils qualitatifs sur site et d’outils quantitatifs pour l’analyse de l’information. Les résultats soulignent que les SE de la zone humide répondent aux besoins socio-économiques et à des aspects socioculturels tels que le patrimoine culturel et l’identité en tant que communautés de pêcheurs. Nous identifions les conflits socio-écologiques émergents qui favorisent la diminution des SE. Nous suggérons des adaptations conceptuelles et méthodologiques pour l’évaluation participative des SE à l’échelle locale.

This research empirically tested the effect of perceived value of ecosystem services on tourists’ intentions to revisit the Aogu coastal wetland in Taiwan. Data were collected using a structured survey and structural equation modeling was then done to test the research hypotheses. Based on the data collected from 230 tourists in the Aogu coastal wetland, the perceived value of ecosystem services of wetland has a positive effect on tourists’ environmental concerns and friendly environmental behavior. Results also indicate that tourists’ environmental concern has a positive effect on friendly environmental behavior and tourists’ friendly environmental behavior has a positive effect on revisit intention to the Aogu coastal wetland. However, the effects of perceived value of ecosystem services and tourists’ environmental concerns on revisit intention were not found to be significant in this study. These results have implications for tourism management of coastal wetlands and the increase in revisit intentions of tourists.

Distribution characteristics of content of soil organic carbon in wetland were studied by the analysis of four soil samples from areas, which were at different depths of soil, collected in the Dagu River estuary of Qingdao during summer of 2014. The result showed that the content of soil organic carbon in coastal wetland of Jiaozhou bay had an overall downward trend with the increase of soil depth. Because of the influence of hydro-salinity environment and tidal action, in regions near the sea, the content of soil organic carbon was less than its counterpart in regions away from the ocean.
