Triassic Keuper evaporites have long been recognized as the main detachment level for thrusting in the Pyrenean fold–thrust belts. The deformed Late Cretaceous–Eocene foreland basin of the Southern Pyrenees has structures and stratal geometries that can be interpreted as related to salt tectonics (e.g. unconformities, rapid thickness variations, long-lived growth fans and overturned flaps), although they have been overprinted by shortening and thrusting. Based on field observations and published maps, we build new structural cross-sections reinterpreting two classic transects of the Southern Pyrenees (Noguera Ribagorçana and Noguera Pallaresa river transects). The sequential restoration of the sections explores the variations in structural style, addressing the role of halokinesis in the tectonic and sedimentary development. In the Serres Marginals area, we propose that salt pillows and diapirs started developing locally during the Mesozoic pre-orogenic episode, evolving into a system of salt ridges and intervening synclines filled with early synorogenic sediments. Rapid amplification of folds recorded by widespread latest Cretaceous–Paleocene growth strata is taken as marking the onset of contractional folding in the area. During Pyrenean compression, folding mechanisms transitioned from dominantly halokinetic to a combination of buckling and differential sedimentary loading. Squeezing of salt diapirs and thrust welding occurred as salt ridges were unroofed. We provide new field observations that lead to a reinterpretation of the regional structural development and contribute to the debate about the role of salt tectonics in the Pyrenees.Supplementary material: Table S1, giving the thickness of the main stratigraphic units, is available at https://doi.org/10.6084/m9.figshare.c.5287737

This paper examines the role of oil and gas companies in community crises in the Niger Delta. The major conclusions are that oil and gas companies have encountered various forms of community crises in their work environment. These crises have negative impact on the performance of these companies. The paper thinks that adequate community relation will significantly reduce the level of also that oil and gas companies in the Niger Delta should adopt community relation strategy through community development projects as this would minimize the level of community crises and hence enhance the performance of oil and gas companies Industry/community crises in the Niger Delta region

Starting Point

Purpose From the background of the dramatic increase of urban tourism, framed by the concept of overtourism, the purpose of this paper is to analyze and discuss current dynamic processes of urban tourism growth, as presented in the scientific literature. With the help of a literature review, this paper aims to discuss current definitions and conceptualizations of overtourism and discuss the driving forces for the growth of urban tourism, thereby situating overtourism in relational to general structural change. Design/methodology/approach This paper builds on a non-exhaustive review of the scientific literature about overtourism and related topics, supplemented by a review of a few central policy documents. Findings Conceptually, overtourism relates to two different, but related, perspectives. The first one concern (negative) experiences of resident population and visitors, whereas the second relates to thresholds for the carrying capacity of destinations. Most of the reviewed literature focuses on three aspects of overtourism: localized problems in inner cities, the supply of unregulated accommodation through Airbnb and Airbnbs as a driving force of gentrification. Important perspectives are missing from the literature, mainly related to the development of driving forces of urban tourism growth in time and space. This observation is the starting point for a discussion on driving forces in an evolutionary perspective with the ambition of relating the growth of urban tourism to long waves of structural development. Research limitations/implications The paper focuses on overtourism in urban contexts, rural tourism is not discussed. Practical implications In identifying the importance of driving forces for understanding the dynamics of urban tourism growth, a holistic view on managing mitigation might be possible. Originality/value The paper adds an evolutionary perspective to the discussion about overtourism and its causes. Thereby, it answers to a need to take tourism seriously in social science, as a major economic, social and ecologic force. In emphasizing the relationship between driving forces on different geographic scales and levels, power relations are highlighted. The paper discusses the role of driving forces for mitigating overtourism. An understanding of the dynamics of driving forces is essential for the development of urban sustainable tourism.

This research discusses the environmental pollution by the capital in the oil-rich Niger Delta region of Nigeria and identifies two historical agents that have the potential to harmonize their social power through a common language that may create a new social and political agency. We argue that the working class and the community-based social movements are necessary but not sufficient agents of transformation in the Nigerian oil-dependent capitalist economy. The cooperation between the global and local sites of resistance is an imperative: a synergy and deliberate action by the conglomerate of trade unions, community-based social movements, nongovernmental organizations, local and global activists, nurtures the potential to transform the capitalist domination, exploitation, and expropriation in Nigeria. Using secondary literature sources, we re-visit the conversation on the role of capital and the pollution of environment in Nigeria through the concept of “Movement of Movements”.

Do Economic Inequalities Generate Political Conflict? An Insight into Civil War and Niger Delta Crisis in Nigeria

Economic Inequalities

The outbreak of political conflicts within countries has been a source of immense human suffering. The serious repercussions and challenges posed by these conflicts direct one to identify the factors that can be political or economic in nature for the outbreak of these domestic conflicts. The present study, without undermining the role of political factors, nevertheless considers economic factors in terms of inequality as significant for the outbreak of conflicts and particularly in understanding the Civil War and Niger Delta Crisis in the context of countries like Nigeria.
