Spatio-temporal dynamics of vegetation cover in North-West Algeria using remote sensing data

Abstract

Land cover change is the result of complex interactions between social and environmental systems which change over time. While climatic and biophysics phenomena were for a long time the principal factor of land transformations, human activities are today the origin of the major part of land transformation which affects natural ecosystems.

Quantification of natural and anthropogenic impacts on vegetation cover is often hampered by logistical issues, including (1) the difficulty of systematically monitoring the effects over large areas and (2) the lack of comparison sites needed to evaluate the effect of the factors.

The effective procedure for measuring the degree of environmental change due to natural factors and human activities is the multitemporal study of vegetation cover. For this purpose, the aim of this work is the analysis of the evolution of land cover using remote sensing techniques, in order to better understand the respective role of natural and anthropogenic factors controlling this evolution.

A spatio-temporal land cover dynamics study on a regional scale in Oranie, using Landsat data for two periods (1984–2000) and (2000–2011) was conducted. The images of the vegetation index were classified into three classes based on Normalized Difference Vegetation Index (NDVI) values and analysed using image difference approach.

The result shows that the vegetation cover was changed. An intensive regression of the woody vegetation and forest land resulted in -22.5% of the area being lost between 1984 and 2000, 1,271 km2 was converted into scrub formations and 306 km2 into bare soil. On the other hand, this class increased by around 45% between 2000 and 2011, these evolutions resulting from the development of scrub groups with an area of 1,875.7 km2.

A couple of Observations on a Possible Interpretation of the Úněticean Grave in Holubice, Praha-západ District

Abstract

The present study is an archaeological and anthropological analysis of a grave pertaining to the Únětice culture and discovered in Holubice, in the Praha-západ district. In the tomb pit the remains of an adult male laid on his right side with his lower limbs sharply bent, had been buried. The skeleton was found to be only partially preserved. Only the frontal bone (os frontale), the major part of the left parietal bone (parietale sin) and a part of the left temporal bone (temporale sin) were preserved. The preserved part of the skull presents signs of a slash trauma including a skull penetration. Even though the bones went through an advanced healing process, the wound had remained open. The nature of the injury indicates that the wound was surgically treated and loose bone fragments were removed. The injury had not been fatal and the individual lived for some time after. The discovered grave is unique not only for its unusual and highly accurately datable grave goods, but above all for standing as proof of the considerable medical knowledge of the people from the Únětice culture.

Narrative des Anthropozän – Systematisierung eines interdisziplinären Diskurses

Abstract

The Anthropocene concept originates from earth system sciences and conceptualizes humanity as a planetary geophysical force. It links current action-oriented time horizons to Earth historical deep time and implies non-separability of natures-cultures. The Anthropocene concept has resonated in debates in natural and social sciences, the humanities and the broader public, serving as an inter- and transdisciplinary bridging concept. Based on an analysis of numerous texts from multiple scientific disciplines and media, this contribution distinguishes five narratives of the Anthropocene: the disaster narrative, the court narrative, the Great Transformation narrative, the (bio-)technological and the interdependence narrative. The five narratives articulate very different perspectives and experiences and transport divergent political, economic, ethical and anthropological values and interests; this is also shown in alternative conceptualizations such as Eurocene, Technocene, Capitalocene or Plantationocene. The analysis reveals that the narratives share significant structural characteristics concerning story, plot, protagonists, spatial and temporal structure and action-oriented emplotment which together can be referred to a meta-narrative of the Anthropocene. Since the partly overlapping, partly contradictory narratives compete for legitimation and dominance in science and the broader public, the findings raise the question whether this struggle will stabilize or undermine the Anthropocene meta-narrative in the long run.

War as nothing but a duel: war as an institution and the construction of the Western military profession

so would not only threaten the existence of states, but even societies ( Haldén and Jackson 2016 ), and result in anarchy that questions the idea of war as organized and instrumental violence. Without institutionalization, no war. The obsolete idea of the duel Comparing war to a duel emphasizes the temporal limits of war. Both in a duel and in war, shared norms allow reaching a decision, making it possible to resolve a conflict once and for all. In fact, the temporal delimitation of war underlies military profession, as shown by the notion that war is just an

reality taking place at a specific time and place. Second, they represent »a form of incorporated history«. And third, they produce an understanding of reality »that is open to conjuncture, contingency, and radical discontinuity«. Overall, the theory provides a framework that allows understanding social reality by linking structures, agents, and institutions in a temporal perspective. Capital is defined as a resource that agents – individuals and organizations – have, can accumulate over time, and use to interact among each other. There are four types of capital
