Contemporary Civil Conflicts in the Nile Basin States

This topic deals with the reasons for the civil conflicts in the Nile Basin Area in Africa. From the geographical point of view, these countries are suffering from the lack of demarcation of boundaries among them. From an economic point of view, they would fight over the abundant economic resources that were taken away wholly by the foreign companies, leaving the crumbs to be disputed over. Additionally, ethnic differences kindle ethnic and religious contradictions. This research will also ascertain some of these reasons, and then review examples of the civil conflicts in the area. Unless these contradictions can be rectified, or mitigated, they will continue to simmer and periodically re‐emerge as a full‐fledged civil war.     

The Kilosa Killings: Political Ecology of a Farmer–Herder Conflict in Tanzania

Farmer–herder conflicts in Africa are often presented as being driven by ‘environmental scarcity’. Political ecologists, however, argue that these conflicts should be analysed within a broader historical and policy context. This article presents a case study of a local conflict in the Kilosa District in Tanzania that tragically culminated in the killing of thirty‐eight farmers on 8 December 2000. To understand the conflict, the authors argue that it is necessary to study the history of villagization and land use in the District, as well as national land tenure and pastoral policies. Attempts at agricultural modernization have fostered an anti‐pastoral environment in Tanzania. The government aim is to confine livestock keeping to ‘pastoral villages’, but these villages lack sufficient pastures and water supplies, leading herders to search for such resources elsewhere. Pastoral access to wetlands is decreasing due to expansion of cultivated areas and the promotion of agriculture. The main tool that pastoralists still possess to counteract this trend is their ability to bribe officials. But corruption further undermines people's trust in authorities and in the willingness of these authorities to prevent conflicts. This leads actors to try to solve problems through other means, notably violence.     

Ceremonial objects or household items? Non‐destructive μ‐XRD2 and μ‐XRF studies on three Neolithic hematite axes from Qatar

Three small stone axes were collected by the joint Qatari‐German South Qatar Survey Project (SQSP) at two places close to the eastern and western coast of Qatar in autumn 2012. Associated with settlement remains, flint artefacts and pieces of ?Ubaid pottery, the implements have been dated to the fifth millennium BCE. Non‐destructive μ‐XRD² and μ‐XRF analyses could, for the first time, prove the use of hematite as the raw material for the manufacture of these tools in Arabia. The absence of major hematite sources in the region and the special characteristics of hematite — a unique metallic shine of polished pieces and the blood‐red colour that appears during the manufacturing process — suggest the highly symbolic character of these objects.     

Global health ethics: the rationale for mutual caring

Despite spectacular twentieth century scientific and technological progress, the world is more inequitable than it was fifty years ago. This is evident both in terms of access to health care for individuals, and in relation to the health of whole populations. Disparities in wealth and health within and between nations are widening inexorably and the rapidly expanding global economy has failed to reduce poverty among those with little if any access to health care. In this context the Universal Declaration of Human Rights remains an unrealized aspiration for the majority of the world's people. Given these realities, no single discipline, or body of knowledge is likely to make much difference. For example, approaches based only on neo–liberal economics, as exemplified by the structural adjustment programmes of the World Bank, have not been successful in promoting health equity. The authors believe that an interdisciplinary approach is required, and that bioethics, an interdisciplinary field, can make a contribution towards improving health globally. To do this, the scope of bioethics should be expanded towards a results–oriented global health ethics, based upon widely shared and foundational values that could be carried forward through five transformational approaches.     

New data on relevant ancient Egyptian wooden artifacts: Identification of wooden species and study of the state of conservation with multidisciplinary analyses

Wood species identification and characterization of its weathering processes are crucial steps in the scientific approach of conservation of wooden cultural heritage. Many precious wooden objects of ancient Egypt are largely present in museums, nevertheless relatively little information is available concerning the nature of timber used and on their status of conservation. To address this gap, the wooden species of three relevant archaeological wood objects (statue, box, and coffin) arising from different Egyptian archaeological sites dated from the Old Kingdom (2,686–2,181 BC) to New Kingdom (1,550–1,069 BC) were deeply studied. Five hardwood and softwood species were identified belonging to Tamarix mannifera, T. gennessarensis, Ficus sycomorus, Vachellia nilotica, and Cedrus sp. Such data confirmed the recurrence of Vachellia and Tamarix among the most common timbers found in ancient Egypt. Scanning electron microscope, Fourier transform spectroscopy, and synchrotron x-ray radiation diffraction were conducted to evaluate the archaeological wood deterioration. The formation of microcracks, biological degradation patterns (fungal colonization), or chemical characterization (accumulation of salts on and in-between wooden cells) were detected. SEM micrographs showed the presence of fungal hyphae and conidial spores on the wooden cells. Significant changes in the chemical wood composition and decrease in the crystallinity index were detected.     

Daylight as a Design Strategy in the Ottoman Mosques of Tunisia and Algeria

This study investigates daylighting design in Tunisian and Algerian mosques from the Ottoman era. It aims to constitute a daylight-based architectural design knowledge which might serve the built heritage preservation as well as supports contemporary environmentally friendly mosques’ and building design. An intensive literature review and a field work research have been undertaken in Tunisia and Algeria in order to survey daylighting devices in the Ottoman mosques era. Nine Tunisian and 14 Algerian mosques, from the Ottoman era, constitute the study corpus. First, an inventory of architectural components and their associated daylighting strategies was carried out. This collected data is then examined by means of a building conformation lecture based on typological, topological, and morphological analysis. This research reveals the existence of an interrelated set of daylighting devices and structural models governing rules in the Ottoman mosque model, site conditions, and previous local architectural styles.
