The Buna River-Protected Landscape is a Managed Nature Reserve and Ramsar site because of its high biodiversity; the water resources at this site represent a crucial element for the ecosystem conservation, especially for the avifauna and ichthyofauna. Water-quality assessment and monitoring are important to the water resource’s ecological value and the health of local populations to improve and promote sustainable agriculture and ecotourism. This paper reports a hydrogeochemical evaluation of sampled waters from the Buna River-Protected Landscape in northern Albania. There exist no previous studies that assess the environmental status of the local groundwater resources. Geochemical surveys of groundwater were conducted in October 2012, and February and June 2013 within the framework of the “International Union of Conservation of Nature”, granted by the Italian Ministry of Foreign Affairs. Twenty samples were analysed to (1) study several parameters with respect to 2000/60/EC and 2006/118/EC, which pose risk for environmental health and (2) evaluate the water quality and all processes that can influence it. The sampled groundwater was classified as calcium bicarbonate, and no evidence of saline intrusion phenomena was obtained, even in the area closest to the coast. Areas with a greater anthropogenic presence show NO3 levels above the European Union thresholds, probably due to the lack of wastewater management systems. A major concern is represented by the widespread presence of organochlorine pesticides, especially with reference to the Hexachlorocyclohexane isomers that have concentrations widely above the thresholds suggested by the European Union

“…This tropical delta is tide-dominated (Hori and Saito 2007), and characterized by a series of distributaries and islands between the states of Amapá and Pará, in the northern region of Brazil. The ADE is formed by two main parts: the Amazon River mouth representing the North Channel and Marajó Bay representing the South Channel.…”

An assessment of urban vulnerability in the Amazon Delta and Estuary: a multi-criterion index of flood exposure, socio-economic conditions and infrastructure

et al. 2016

The Amazon Delta and Estuary (ADE) is a region of continental and global ecological importance. Controversy, many of the basic infrastructure and services essential for quality of life and sustainable development of this delta are absent. Using a conceptual model to define socio-economic vulnerability in the urban ADE, a thorough assessment of indicators including sanitation services, housing conditions, household income, population, flood risk and unplanned settlements was conducted in 41 cities at the census sector scale (n = 2938). A multi criterion index was applied to classify urban vulnerability from three dimensions: flood exposure, socio-economic sensitivity and infrastructure. This is the first study to examine urban vulnerability within and between urban areas of the ADE. Results indicated that most of the urban sectors of the ADE are exposed to potential risks due to a combination of flood hazards, poverty and basic structural deficiencies such as insufficient drinking water or inadequate waste water collection, with several sectors being afflicted by similar problems. The assessment of vulnerability indicates that 60-90 % of the urban population live in conditions of moderate to high degree of vulnerability. The ADE cities presented a pattern where vulnerability increases from city center to their newly developed urban areas. Inadequate planning coupled with rapid urbanization has contributed to the development of unplanned settlements in almost half of the urban sectors of the ADE. Combined, these factors contribute to widespread socio-economic vulnerability along the urban spaces of the ADE, increasing exposure to health risks and more frequent seasonal and stochastic events such as storm surges and high flooding levels.

“…This seminal classification became widely adopted as it allows for individual river mouths to be positioned in a classificatory diagram based on the qualitative analysis of the perceived influence of river flow, waves and tides. More recently, Hori and Saito (2008) [18] proposed some quantitative indices based on tidal range, wave height and suspended sediment load to distinguish between waveinfluenced, mixed tide-wave-influenced, and tide-influenced deltas, based on the explicit assumption that all deltas are strongly influenced by fluvial discharge and sediment load that determine delta growth.…”

Deltaic systems are among the most dynamic and productive environments on Earth and many have a high population density. Deltas play a central role in food and water security but are increasingly facing hazards such as submergence, riverine and coastal flooding, and coastal erosion. This paper synthesizes efforts of the Belmont Forum Deltas project, an international network of interdisciplinary research collaboration with focal areas in the Mekong, the Ganges Brahmaputra, and the Amazon deltas. The inherent complexity and dearth of knowledge about deltas require disciplinary expertise to advance jointly with interdisciplinary collaboration. An overarching research framework articulates focal research areas and collaborative modules, serving as an umbrella for both crosscutting and specific research questions. These modules have allowed for common definition of goals, responsibilities, and products, but flexible and decentralized disciplinary and interdisciplinary collaborations. Self-organization within and across areas of expertise has proven effective in bringing collaborators to commit to specific efforts. Knowledge co-production workshops focusing on vulnerability and risk have successfully strengthened interactions with regional organizations. As a distributed network, challenges remain in terms of type of and level of interaction and hands-on collaborative work among research partners, including joint fieldwork, but successes far outweigh difficulties. To illustrate these points, we present a review of three research domains built upon different arrangements of disciplinary and interdisciplinary collaborations: advancing biophysical classifications of deltas, understanding deltas as coupled socialecological systems, and analyzing and informing social and environmental vulnerabilities in delta regions. -Title change: we deleted 'BF-Deltas Project' from the title; -Editing section 2. We edited the section and included two paragraphs about how the project; came together and how the team responded to the funding call from the Belmont Forum program; -We added a discussion about funding to the conclusion; -We added annotated bibliographical notes to few specific references; Let me know if there are additional editing we would like us to make.On behalf of the co-authors, thanks for your consideration, -The inherent complexity and dearth of knowledge about deltas require disciplinary expertise to advance jointly with interdisciplinary collaboration, both involving teamwork.-A shared research framework has provided common language and goals, while allowing flexible and self-organizing collaborations.-Knowledge co-production workshops focusing on vulnerability and risk offer a productive venue for collaboration with regional partners and stakeholders.-Distributed research networks face challenges in terms of types of and level of interaction and hands-on collaborative work among research partners.-Deltas are sentinels of regional and global changes offering opportunities for new collaboration between and w...
