Monitoring jellyfish outbreaks along Israel's Mediterranean coast using digital footprints.

With mounting global concerns about jellyfish outbreaks, monitoring their occurrence remains challenging. Tapping into the wealth of digital data that internet users share online, which includes reports of jellyfish sightings, may provide an alternative or complement to more conventional expert-based or citizen science monitoring. Here, we explore digital footprints as a data source to monitor jellyfish outbreaks along the Israeli Mediterranean coast.

Introducing a temporal DPSIR (tDPSIR) framework and its application to marine pollution by PET bottles.

Environmental governance is highly sensitive to temporal dynamics, due to the ever-accelerating rate of technological changes, the cumulative nature of environmental impacts and the complexity of multi-level environmental policy processes. Yet, temporality is generally only implicitly included in frameworks used for describing or assessing policy response in the broad context of social-ecological systems, such as the widely used Driver-Pressure-State-Impact-Response (DPSIR) framework. As a result, the application of such frameworks often does not give due attention to questions of temporality, with potential negative impacts on attaining environmental goals.

A coastal Ramsar site on transition to hypoxia and tracking pollution sources: a case study of south-west coast of India.

Coastal lakes and estuaries are considered economic drivers for coastal communities by delivering invaluable economic and ecosystem services. The coastal ecosystems are facing recurrent hypoxia events (dissolved oxygen; DO < 2.0 mg L) and are emerging as a major threat to ecosystem structure and functioning.

Geolocated social media data counts as a proxy for recreational visits in natural areas: A meta-analysis.

Geolocated social media data counts are increasingly used as proxy for number of visits in natural areas, including their spatial and temporal distribution. This paper synthesizes the empirical evidence concerning the correlation of social media data counts and visits through multi-level meta-analytical models. Analysis of 355 correlations from 41 studies reveals a strong correlation for annual number of visits over multiple sites (pooled Pearson's r = 0.

Stakeholder views of source separation collection programme in East São Paulo, Brazil.

The investigation of the views of the stakeholders involved in the municipal solid waste separate collection programme (CP) performed in the East Zone of the city of São Paulo is presented in this paper. Aiming to obtain the necessary information to be analysed, interviews with the manager of the Municipal Urban Cleaning Authority (MUCA) of the city, with leaders of recycling worker cooperatives (WCs), and citizens were performed using semi-structured questionnaires. The analysis was performed using the software "IRAMUTEQ".

Using social media to estimate visitor provenance and patterns of recreation in Germany's national parks.

Social media data are increasingly utilised as a low-cost alternative to visitor surveys in characterising nature-based recreation. However, the information available on individual users is limited and typically does not include provenance, restricting the potential applications and impact of the data. Here we investigate a methodology to estimate social media visitors' home locations at various spatial scales and apply it to the entire network of national parks in Germany.

Spatial analysis, local people's perception and economic valuation of wetland ecosystem services in the Usumacinta floodplain, Southern Mexico.

The Usumacinta floodplain is an exceptional area for biodiversity with important ecosystem services for local people. The main objective of this paper was to estimate reference values and define local perceptions of ecosystem services provided by wetlands and overlapping them with spatially explicit socioeconomic and biodiversity indicators. We used the Usumacinta floodplain as an example of a territory where high dependence of rural people on ecosystem services is confronted with development projects that threat the flow of ecosystem services, thus affecting rural people well-being.

A crowdsourced valuation of recreational ecosystem services using social media data: An application to a tropical wetland in India.

Online social media represent an extensive, opportunistic source of behavioral data and revealed preferences for ecosystem services (ES) analysis. Such data may allow to advance the approach, scale and timespan to which ES are assessed, mapping and valued. This is especially relevant in the context of developing regions whose decision support tools are often limited by a lack of resources and funding.

Interbasin water transfer for the rehabilitation of a transboundary Mediterranean stream: An economic analysis.

Global demand for freshwater is increasing as human population grows, climate changes and water resources are being overexploited. Consequently, many freshwater ecosystems, particularly in water-stressed regions, are severely degraded. Here we present a unique case of an Interbasin Water Transfer (IWT) project aiming at ecosystem rehabilitation and recreation enhancement of an intermittent transboundary stream (Ayun, Israel).

Analysis of intensity and spatial patterns of public use in natural treatment systems using geotagged photos from social media.

Patterns of public use in 273 natural treatment systems worldwide are investigated by means of geotagged data from two popular photo-sharing websites, using spatial analysis and regression techniques. Standardized Major Axis (SMA) regression is found to perform better than other univariate calibration models in terms of goodness of fit with reported visitation frequencies and predictive accuracy, and is used to predict visitation rates in 139 systems that are associated with at least one geotagged photograph. High visitation rates are found in free-water surface (FWS) constructed wetlands and mixed pond-constructed wetlands systems, as well as systems treating surface water or stormwater runoff.

Benefits of coastal recreation in Europe: identifying trade-offs and priority regions for sustainable management.

This paper examines the welfare dimension of the recreational services of coastal ecosystems through the application of a meta-analytical value transfer framework, which integrates Geographic Information Systems (GIS) for the characterization of climate, biodiversity, accessibility, and anthropogenic pressure in each of 368 regions of the European coastal zone. The relative contribution of international, domestic, and local recreationists to aggregated regional values is examined. The implications of the analysis for prioritization of conservation areas and identification of good management practices are highlighted through the comparative assessment of estimated recreation values, current environmental pressures, and existing network of protected sites.

Effects of land use changes on the ecosystem service values of coastal wetlands.

Changes in the coastal landscape of Southern Sinaloa (Mexico), between 2000 and 2010, were analyzed to relate spatial variations in wetlands extent with the provision and economic value of the ecosystem services (ES). Remote sensing techniques applied to Landsat TM imagery were used to evaluate land use/land cover changes while the value transfer method was used to assess the value of ES by land cover category. Five wetland types and other four land covers were found as representative of the coastal landscape.
