Changing Landscape and Oral Memory in South-Central Zimbabwe: Towards a Historical Geography of Chishanga, c. 1850-1990* This paper is based on my current research on the history of the same area. I am deeply indebted to the Sida/SAREC grant, which financed the project as well as to discussions I have had on earlier versions of this paper with Terence Ranger and Gilbert Pwiti. I am also grateful to Chief Mapanzure, Mr Mapope Tavarera, Mr Raphael Manyoka Gwenhamo, and Mr Kokerai Chikozho who welcomed and cooperated with me on issues that have greatly affected the scope of this paper. This paper benefited immensely from the mentorship of my late father, Tungamirayi Mazarire, who died as I was writing it and did not live to see the fruits of his efforts. It is to him that I dedicate it.

Jurassic sedimentary rocks of southern to central Quesnellia record the history of the Quesnellian magmatic arc and reflect increasing continental influence throughout the Jurassic history of the terrane. Standard petrographic point counts, geochemistry, Sm–Nd isotopes and detrital zircon geochronology, were employed to study provenance of rocks obtained from three areas of the terrane. Lower Jurassic sedimentary rocks, classified by inferred proximity to their source areas as proximal or proximal basin are derived from an arc source area. Sandstones of this age are immature. The rocks are geochemically and isotopically primitive. Detrital zircon populations, based on a limited number of analyses, have homogeneous Late Triassic or Early Jurassic ages, reflecting local derivation from Quesnellian arc sources. Middle Jurassic proximal and proximal basin sedimentary rocks show a trend toward more evolved mature sediments and evolved geochemical characteristics. The sandstones show a change to more mature grain components when compared with Lower Jurassic sedimentary rocks. There is a decrease in εNdT values of the sedimentary rocks and Proterozoic detrital zircon grains are present. This change is probably due to a combination of two factors: (1) pre-Middle Jurassic erosion of the Late Triassic – Early Jurassic arc of Quesnellia, making it a less dominant source, and (2) the increase in importance of the eastern parts of Quesnellia and the pericratonic terranes, such as Kootenay Terrane, both with characteristically more evolved isotopic values. Basin shale environments throughout the Jurassic show continental influence that is reflected in the evolved geochemistry and Sm–Nd isotopes of the sedimentary rocks. The data suggest southern Quesnellia received material from the North American continent throughout the Jurassic but that this continental influence was diluted by proximal arc sources in the rocks of proximal derivation. The presence of continent-derived material in the distal sedimentary rocks of this study suggests that southern Quesnellia is comparable to known pericratonic terranes.

Flash floods, debris flows and landslide disaster on the steep sloping terraces of hilly region are so challenging that even a real time hydro-meteorological forecasting system would not be applicable for all cases in Nepal. Flash floods are localized in short ranges with respect to time and distance; and it is very difficult to measure these flash floods in time. On the other hand, such phenomena need to be assessed for sustainable design of hydro- structures and for relocating the settlements from risk areas. A study was carried out to find the suitable relationship between area and extreme flood as well as area and extreme rainfall depth. Analysis is mainly based on the case of torrential rains in July 1993 over south central Nepal, which caused floods and debris torrents those were probably the worst in the disaster history of Nepal damaging lives and properties in Nepal during the 20th century. A relation for rainfall depth and other relation for specific flood are presented in this paper.Keywords: South-central Nepal; specific discharge; rainfall intensity; depth area duration.DOI: http://dx.doi.org/10.3126/jhm.v6i1.5487Journal of Hydrology and Meteorology, Vol. 6, No. 1 44-48

AbstractThe Central Siberian Plateau was last geographic area in Eurasia to become habitable by modern humans after the Last Glacial Maximum (LGM). Through comprehensive mitochondrial DNA genomes retained in indigenous Siberian populations, the Ket, Tofalar, and Todzhi - we explored genetic links between the Yenisei-Sayan region and Northeast Eurasia over the last 10,000 years. Accordingly, we generated 218 new complete mtDNA sequences and placed them into compound phylogenies along with 7 newly obtained and 70 published ancient mt genomes. Our findings reflect the origins and expansion history of mtDNA lineages that evolved in South-Central Siberia, as well as multiple phases of connections between this region and distant parts of Eurasia. Our result illustrates the importance of jointly sampling modern and prehistoric specimens to fully measure the past genetic diversity and to reconstruct the process of peopling of the high latitudes of the Siberian subcontinent.

Abstract Koshe town is the administrative and commercial center of Mareko woreda.1 It is found in Gurage Zone Southern Nation Nationalities and Peoples Regional State. According to the tradition the origin of the name “Koshe” is originated from the plant which called by the name Koshe which abundantly grow in the area. The establishment of Koshe town is directly associated with the five years Italian occupation. Due to the expansion of patriotic movement in the area Italian officials of the area forced to establish additional camp in the area in a particular place Koshe. This paper explores the role of Fascist Italy for the establishment of Koshe town. The former weekly market shifted its location and established around the Italian camp. Following the evacuation of Fascist Italy the Ethiopian governments control the area. During the government of Emperor Haile Selassie Koshe town got some important developmental programs. The most important development was the opening of the first school by the effort of the Swedes.2 The Military regime (Derg)3 also provided important inputs for the urbanization of Koshe town. This research paper observes the development works that flourish in Koshe during the reign of Emperor Haile Selassie and the Military regime, and also asses the role of different organizations for the urbanization of Koshe town.

Glacial Cover

The south-central Intermontane belt of British Columbia has a complex architecture comprising late Paleozoic to Mesozoic volcanic and plutonic arc magmatic suites, marine and nonmarine clastic basins, high-grade metamorphic complexes, and accretionary rocks. Jurassic and Cretaceous clastic basins within this framework contain stratigraphy with hydrocarbon potential. The geology is complicated by Cretaceous to Eocene deformation, dismemberment, and dislocation. The Eocene to Neogene history of the southern Intermontane belt is dominated by non-arc volcanism, followed by Pleistocene to Recent glaciation. The volcanic and glacial cover makes this a difficult region to explore for resources. Much recent work has involved re-evaluating the challenges that the overlying volcanic cover has historically presented to geophysical imaging of the sedimentary rocks in this region in light of technological advances in geophysical data collection and analysis. This paper summarizes the lithological and stratigraphic framework of the region, with emphasis on description of the sedimentary units that have been the targets of hydrocarbon exploration.
