Article
Full-text available
Half the population of China live in coastal zones where 70% of large cities are also located. Intensive human activities pose significant environmental and ecological hazards to these cities that are already vulnerable to natural hazards and climate change. The sustainable development of coastal cities is thus both a national and international iss...

This study explores the use of satellite-based LULC (Land Use / Land Cover) data while simultaneously correcting potential evapotranspiration (PET) input with Leaf Area Index (LAI) to increase the performance of a physically distributed hydrologic model. The mesoscale hydrologic model (mHM) was selected for this purpose due to its unique features....

Electronic waste (e-waste) is a rapidly developing environmental problem particularly for the most developed countries. There are technological solutions for processing it, but these are costly, and the cheaper option for most developed countries has been to export most of the waste to less developed countries. There are various laws and policies f...
Article
Natural and anthropogenic pressures drive coastal eutrophication worldwide, depending on the system's physical and biogeochemical dynamics in multiple spatial and temporal scales. Understanding the complexity of this process is essential to support management efforts and sustainability. Nutrients load to the Bay of Santa Catarina Island (BSCI), an...
Article
Disruptions to global science networks have followed COVID-19 restrictions. Rather than wait for a return to normal, we propose four areas that can ensure a productive and collaborative future for marine science.
Article
Transboundary marine socio-ecological systems (SESs) are complex and dynamic systems. Enhancing the sustainability of such systems requires adaptive governance supported by polycentric structures. However, adaptive governance of marine SESs across national boundaries can be challenging, as significant differences in institutional arrangements for r...
Article
Variations in the physico-chemical characteristics of estuaries, such as surface water salinity and temperature, lead to the establishment of gradients that are closely related with the distribution of nutrients and suspended sediment. This affects light penetration, which in turn influences Chlorophyll-a (Chl-a) concentration and primary productiv...
Article
Full-text available
Coastal eutrophication caused by anthropogenic nutrient inputs is one of the greatest threats to the health of coastal estuarine and marine ecosystems worldwide. Globally, ∼24% of the anthropogenic N released in coastal watersheds is estimated to reach coastal ecosystems. Seven contrasting coastal ecosystems subject to a range of riverine inputs of...
Article
Full-text available
Coastal and marine management require the evaluation of multiple environmental threats and issues. However, there are gaps in the necessary data and poor access or dissemination of existing data in many countries around the world. This research identifies how remote sensing can contribute to filling these gaps so that environmental agencies, such a...
Article

Mangrove degradation threatens the capacity of these important ecosystems to provide goods and services that contribute to human wellbeing. This study uses a deliberative choice experiment to value non-market mangrove ecosystem services (ES) at Mida Creek, Kenya. The attributes assessed include "shoreline erosion protection", "biodiversity richness...
Article
This study was implemented in the context of the emerging concept of aesthetic ecosystem services (AES) of coastal protected dunes and forests. The main problem addressed was that many coastal management research case studies focusing on AES still rely on the objectivist paradigm, eliciting aesthetic values based on objective sets of criteria indep...
Article
The management of forest ecosystems globally is shifting from a top-down-approach, through centralised management by the state, to a more inclusive bottom-up approach involving community participation. Increasingly, there is a realisation that sustainable management of natural resources is dependent on the inclusion of local people or institutions...
Article
This article explores the prospects for adaptive governance in a proposed marine transboundary conservation initiative in East Africa. Adaptive governance that involves interdependent state and non-state actors learning and taking action on joint environmental problems is suggested for effective transboundary resource governance. Using the concept...

The Mekong Delta, located in Southern Vietnam, is one of the most affected areas in the world by climate change and sea level rises, especially flooding. Therefore, flood mapping is essential for understanding the flood regime and mitigating its impacts. Remote sensing and GIS can support the accurate and area wide evaluation of floods. In this stu...
Article
The study region in Sagres, SW Portugal, is subject to natural eutrophication of coastal waters by wind-driven upwelling, which stimulates high primary productivity facilitating the recent economic expansion of bivalve aquaculture in the region. However, this economic activity is threatened by harmful algal blooms (HAB) caused by the diatoms Pseudo...

Restoration strategies for coral reefs are usually focused on the recovery of bio-physical characteristics. They seldom include an evaluation of the recovery of the socio-ecological and ecosystem services features of coral reef systems. This paper proposes a conceptual framework to address both the socio-ecological system features of coral reefs wi...
