Abstract
Rivers have played a defining role in the global development of human societies and culture. This will undoubtedly continue in the twenty-first century with a growing demand for water, increasing pollution of river channel and floodplain environments, and anthropogenic global warming-related changes in the frequency of floods and droughts. These will have major environmental and societal impacts worldwide. We consider how rivers initially shaped societies, and then how urbanisation, industrialisation and intensified agriculture have more recently transformed river systems, so compromising planetary health and human ways of life. So where do we go from here? Humanity now faces an existential environmental catastrophe of its own making, and it will be on the world's most densely populated floodplains where this crisis will be played out. We highlight likely areas facing the greatest challenges. Ironically, many of these are where ancient civilisations began. Interdisciplinary catchment-based approaches, and new technologies such as those based on satellite imagery and unmanned aerial vehicles, are now beginning to address pressing societal and planetary problems in the unfolding climate crisis.

Abstract
Over the last decades, freight networks and multimodal integration have been shaped by complex driving forces. Globalisation and consumerism in society significantly contributed to intensify the demand for services in freight transport. Technological breakthroughs and the related development of innovation fed the constant search for faster and cheaper services on a global scale. Altogether, these driving forces have boosted a rapid increase in the volume of freight transport by means of road transport. While industry had modified its networks to meet the demand, the pandemic period brought new challenges to freight networks, forcing the different modes of transport to adapt to the unexpected environment. Some of those reactive solutions might have been adopted temporarily. However, others are expected to become permanent and their deployment in the short-medium term remains to be seen.
This chapter presents an overview of the challenges and respective solutions that were initiated throughout the pandemic period, mostly in response to concerns related to social distance and untypical demand needs. This overview allows for a better foretelling of the future directions and developments in the freight network elements. This chapter approaches the way forward for cities and industry regarding the lasting pandemic effects on freight networks. Such an overview is complemented by an input from an expert survey in order to evaluate the social acceptability towards the expected solutions that are emerging. The outcome of the chapter highlights the main guidelines for the freight networks in the future and correlates them with the pandemic’s permanent effects.

Abstract
History has taught us that every aspect of the world around us is changing. Right from its formation, the earth has been evolving climatically, edaphically, and biotically to its present state. The forcing for all these changes in the past was natural, and human activities had least influence till the industrial revolution. Since the beginning of the 18th century, human activities associated with the industrial revolution have changed the composition of the atmosphere and thereby having a greater influence on the earth's climate. The use of fossil fuels like coal and oil coupled with deforestation has increased the concentration of heat-trapping “greenhouse gases,” which prevent the heat from the earth escaping to space. Because of this, the very greenhouse gases, which helped sustain life on the earth under normal circumstances, have become detrimental due to its higher concentration. Several models have predicted that the rising concentrations of greenhouse gases produce an increase in the average surface temperature of the earth over time. Rising temperatures may, in turn, produce changes in precipitation patterns, storm severity, and sea level, commonly referred to as “climate change.” The Intergovernmental Panel on Climate Change (IPCC) defines climate change broadly as “any change in climate over time whether due to natural variability or as a result of human activity.” The United Nations Framework Convention on Climate Change (UNFCCC) defines climate change as “a change of climate that is attributed directly or indirectly to human activity, that alters the composition of the global atmosphere, and that is in addition to natural climate variability over comparable time periods.”

Abstract
The present study evaluates the principal forms of socioenvironmental damage suffered by local traditional populations and indigenous communities as a result of the installation and operation of the Pecém Industrial and Shipping Complex. The main problem being pollution in the municipalities of São Gonçalo do Amarante and Caucaia, which is in the Brazilian state of Ceará. As a theoretical framework, we use the concept of “environmental justice,” and “environmental racism.” The latter were used to understand the process of “deterritorialization” of these communities that resulted in extensive impacts on the natural environment, as well as the way of life and productive practices of these communities. Our analyses confirm the destruction of the means that allow noncapitalist exploitation of natural resources, such as artisanal fisheries, subsistence farming, and the use of commons. We show how all these processes are constitutive of environmental injustice and environmental racism. These may contribute to the organization of the resistance and struggle of the affected populations, namely indigenous peoples and traditional communities.

Abstract
Purpose
This chapter examines the torsions and blind spots that structure the contemporary debate on the politics and policy of aviation. It also generates different scenarios for the future of air travel, which can help to unblock the current impasse about the perceived costs and benefits of aviation and its attendant infrastructural needs.
Originality
This chapter characterises and evaluates the competing frames that organise the contested realities of air transport. By mapping out the current fault lines of aviation politics and policy, the chapter is also able to delineate four main scenarios regarding the future of aviation, which we name the ‘post-carbon’, ‘high-modernist’, ‘market regulation’ and ‘demand management’ projections respectively.
Methodology/approach
The chapter problematises and criticises the existing literature, policy reports and stakeholder briefings that inform the contemporary standoff in UK aviation policy. It uses the definition of sustainable development as a heuristic device to map and identify the fault lines structuring contemporary debates on aviation futures. It then builds upon this analysis to delimit four different scenarios for the future of flying.
Findings
The chapter analyses the contested realities of aviation politics. It re-affirms the political nature of such divisions, which in turn structure the rival understandings of aviation. The analysis suggests that the identified fault lines are constantly reiterated by competing appeals to ambiguous and contradictory evidence-bases or policy frames. Ultimately, the chapter claims that any significant reframing of aviation policy and politics rests on the outcome of political negotiations and persuasion. But it also depends on the broader views of citizens and stakeholders about the future challenges facing society, as well as the way in which governments and affected agents put in place and coordinate the multiple arenas in which a dialogue over the future of aviation can be held. Aviation futures cannot be reduced to the narrow confines of the technical merits or claims surrounding the feasibility of policy instruments.
