Résumé :

Ecological and socioeconomic aspects of subterranean hydrosystems have changed during the past 40–50 years. The major environmental pressures (mainly anthropogenic ones) impact the quantity and quality of groundwater resources and the state of subsurface ecosystems, and it is expected that the environmental pressures on groundwater will continue, at least until 2025, unless new environmental policies change this state of affairs. The world demographic increase and the general rise of water demand constitute one of the major environmental pressures on groundwater ecosystems especially in less d

In his most recent book, James Scott presents us with a ‘deep history’ of the alluvial lowlands of Mesopotamia, from early domestications in the Neolithic to the emergence and consolidation of early states. Although the focus lies on Mesopotamia in these periods, Scott delves into the beginnings of the human use of fire in the Palaeolithic and draws on comparative developments in Southeast Asia, Egypt, Greece, Rome and elsewhere. He poses large questions: Why did people move into densely packed villages—‘Neolithic multispecies resettlement camps’—accompanied by the plants and animals they dome

Résumé :

Sustainability is the possibility of all people living rewarding lives within the means of nature. Despite ample recognition of the importance of achieving sustainable development, exemplified by the Rio Declaration of 1992 and the United Nations Millennium Development Goals, the global economy fails to meet the most fundamental minimum condition for sustainability—that human demand for ecosystem goods and services remains within the biosphere's total capacity. In 2002, humanity operated in a state of overshoot, demanding over 20% more biological capacity than the Earth's ecosystems could rege

The article describes the ecological state of the Ural River at the present stage. Hydrochemical regime of the reservoir is an important indicator to regulating the number of water resources. As the Ural River is the transboundary reservoir, it is prone to contamination from various areas in the upper and middle reaches. Monitoring of the ecological state of the Ural River showed the presence of anthropogenic pollution. The hydrochemical regime of the reservoir is subject to changes in seasonal variations in water composition. In spring, with flood waters, the main pollution enters the river,

Rivers belong to the world’s most complex ecosystems but increasing demands for water are degrading rivers worldwide. The increase in human populations and activities has resulted in an intense and difficult conflict between the development of rivers as a natural resource and their function as living ecosystems. It is now widely recognized that a naturally variable flow regime is required to sustain freshwater ecosystems. Many countries that experience river degradation have started to implement environmental flows, i.e. the unallocated flow purposely preserved in a river. The objectives of th

Résumé :

AbstractThis chapter aims to offer readers an entry point to the deep discussion of this volume and the rationale for the “Finance 4.0” system described in later chapters. What is money, why is it designed this way, and what could it become in the crypto age? The chapter contains three parts. The first part describes in rough strokes the basic functions of money and how today’s fiat money system implements them. The second part offers a modest critique of the fiat money system, arguing that many problems take root in the intimate power relationship between “money and state.” The final part presents two cases that address some of the shortcomings. The first is Bitcoin that infamously pursues a state-independent, decentralized conception of money. The second is Finance 4.0, a system that proposes a participatory multi-dimensional money system with built-in incentives for sustainable behavior. If more readers feel empowered to enter the public debate for a better money system in the twenty-first century, this short introduction achieved its aim.

Résumé :

AbstractInvasive species and their management represent a complex issue spanning social and ecological systems. Invasive species present existing and potential threats to the nature of ecosystems and the products and services that people receive from them. Humans can both cause and address problems through their complex interactions with ecosystems. Yet, public awareness of invasive species and their impact is highly uneven, and public support for management and control of invasive species can be variable. Public perceptions often differ markedly from the perspectives of concerned scientists, and perceptions and support for management are influenced by a wide range of social and ecological values. In this chapter, we present a broad survey of social science research across a diversity of ecosystems and stakeholders in order to provide a foundation for understanding the social and cultural dimensions of invasive species and plan more effective management approaches. This chapter also addresses tribal perspectives on invasive species, including traditional ecological knowledge, unique cultural dimensions for tribes, and issues critical to engaging tribes as partners and leaders in invasive species management. Recognizing that natural resource managers often seek to change people’s perceptions and behaviors, we present and discuss some promising approaches that are being used to engage human communities in ways that empower and enlist stakeholders as partners in management.

Résumé :

AbstractThere are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_Programmable Water-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.

AbstractThis chapter introduces the idea of transformative change for sustainability and its relevance to the concept and practices of socio-ecological production landscapes and seascapes (SEPLS). First, it lays out the context where transformative change has been described as a way of fundamental, system-wide reorganisation of technological, economic and social factors to achieve the global goals of sustainability and nature conservation. Following a literature review, which offers the current state of knowledge concerning transformative change, the chapter discusses how SEPLS management relates to the idea of transformative change. In particular, it highlights the potentials of integrated approaches to managing SEPLS that can result in multiple benefits beyond biodiversity conservation and facilitate transformative change while addressing well-being needs and challenges specific to the local contexts. With this background and conceptual underpinning, the chapter provides the scope and objectives of the book as well as the key questions followed by the case study chapters. Finally, it introduces the organisation of the book and presents an overview of the case studies.

Résumé :

AbstractTransformation, transition, and paradigm shift are increasingly applied concepts in literature on climate resiliency to describe changes in society and the environment. Here, we considered mangroves to be dynamic socio-ecological systems, subject to increasing anthropogenic pressures that present complex challenges for the design of effective coastal governance. Analysing these systems through a participatory approach, we consulted a community who lives in close relationship with mangroves, the Alitas farmers of Infanta, Quezon Province, Philippines. This community has improved decision-making processes for the development of adaptation strategies to climate change. In turn, a sustainably managed and conserved mangrove forest promotes human well-being and resilience, particularly for those households whose livelihoods are dependent on the resources that mangroves provide. This paper examined the importance of mangrove land management that addresses climate change hazards. We synthesised various perspectives on the importance of mangrove conservation for enhancing climate resiliency by: (1) describing the climate-related hazards that affect local communities and mangroves; (2) describing socio-institutional structures influencing effective mangrove conservation and local resilience; and (3) identifying climate change adaptation strategies that promote local development and mangrove conservation. This paper establishes a collaborative management framework for future risk-resilience management that operates alongside coastal communities within the Philippines and across the global stage.

Résumé :

A 20% increase of the carbon dioxide concentration in the atmosphere during the last century and a dramatic increase in nutrient load to marine systems due to human activity have resulted in pronounced carbon cycle transformation in coastal areas. Acidification and carbon dioxide increasing in the water column and appearance of oxygen minimum zones are reported for the worldwide coast. This makes ecological assessment of aquatic systems, including key cycles of elements, an important social and scientific task. In this study, we present information on the inorganic part of the carbon cycle and

Résumé :

The forest of Chettaba is for ecotourism. Managed by the Forest Conservation of Constantine, this site is formed of several forestry species (hardwood and softwood) spread over an area of 3010 ha. The objective of this study is to estimate the viability of this site through the permanent monitoring of the current state of the forest including biodiversity and pressures. The collection of data related to it had recourse to a forest inventory and an inventory of pressures. The condition was assessed by analyzing these components. The various analyses conducted during this study revealed that the

Résumé :

This study was conducted to inventory, classify, and map soils and vegetation within the ecosystems of Katmai National Park and Preserve (KATM) using an ecological land survey (ELS) approach. The ecosystem classes identified in the ELS effort were mapped across the park, using an archive of Geo-graphic Information System (GIS) and Remote Sensing (RS) datasets pertaining to land cover, topography, surficial geology, and glacial history. The description and mapping of the landform-vegetation-soil relationships identified in the ELS work provides tools to support the design and implementation of
