Local level rainfall and temperature variability in drought-prone districts of rural Sidama,central rift valley region of Ethiopia

ABSTRACT

The purpose of this study is to examine local level spatiotemporal rainfall and temperature variability in drought-prone districts of rural Sidama, Central Rift Valley region of Ethiopia. The study used 129 gridded monthly rainfall and temperature data of 32 years (1983–2014). The gridded rainfall and temperature records were encoded into GIS software and evaluated through different statistical and geospatial techniques. Mann-Kendal rank test and F distribution tests were used to test temporal and spatial statistical significance, respectively, of the data. The analysis revealed that Belg and Kiremt are the main rainfall seasons, constituting 81% of the annual rainfall. Although annual, Kiremt, and Belg rainfall amounts appear to have decreased over time, the decreasing trend is statistically significant only for Belg rainfall records. On the other hand, rainfall standard anomaly results indicated seven droughts of different magnitudes: one extreme, two severe, and four moderate. The study also revealed increasing temperature trends over the years under consideration that are statistically significant. The findings of this study on rainfall contradict other findings obtained around the study area. Thus, climate change adaptations need to focus on location-specific climate data analysis so that the intended adaptive interventions can be successful.     

Revisiting Sustainable Development of Dry Valleys in Hengduan Mountains Region

Dry valleys are a striking geographic landscape in Hengduan Mountains Region and are characterized by low rainfall, desert type of vegetation and fragile environment. Past efforts and resources have been concentrated mainly on rehabilitation of degraded ecosystem and fragile environment, particularly reforestation, while socio-economic development has been largely overlooked. Despite successes in pocket areas, the overall trend of unsustainability and environmental deterioration are continuing. It is important to understand that uplift of the Tibetan Plateau is the root cause of development of dry valleys, and development and formation of dry valleys is a natural process. Human intervention has played a secondary role in development of dry valleys and degradation of dry valleys though human intervention in many cases has speeded up environmental degradation of the dry valleys. It is important to understand that dry valleys are climatic enclaves and an integrated approach that combines rehabilitation of degraded ecosystems and socio-economic development should be adopted if the overall goal of sustainable development of dry valleys is to be achieved. Promotion of niche-based cash crops, rural energy including hydropower, solar energy, biogas and fuelwood plantation is recommended as the priority activities.

Defending national linguistic territories in the European Single Market: towards more transnational geolinguistic analysis

This paper calls for more analysis of contemporary transnational linguistic movements. Geographers have hitherto focused on linguistic problems within states and paid less attention to issues that arise as languages, notably English, are used internationally across state boundaries. It does this by examining a conflict that arose when forces integrating the supranational European Single Market space came into conflict with a Member State's determination to protect the linguistic 'integrity' of its national territory. This conflict would appear to be a precursor of similar ones to come as languages increasingly compete in a linguistic market within an integrating Europe and a globalizing world.     

Managing sustainable farmed landscape through 'alternative' food networks: a case study from Italy

This paper focuses on a case study of an 'alternative' food network based in the Abruzzo National Park, Italy, to explore how ideas of sustainable farmland management can be expressed through broader understandings of developing networks of care concerned with local economies and societies, high-quality specialist food products, particular 'traditional' farming practices and livestock breeds, as well as the ecology of a farmed landscape. The scheme allows customers, internationally as well as in Italy, to 'adopt' a milking sheep on a large mountain farm. In return, adopters are sent food products from the farm. The adoption scheme is inter-twined with an agri-tourism project which provides accommodation, runs a restaurant and engages in educational activities. The scheme is the result of the individual initiative of its founder, and is associated with a strongly expressed ethical position concerning the value of sustaining valued local rural landscapes and lifestyles, and the importance of 'reconnecting' urban dwellers with rural areas, farming and 'quality' food production. Yet the localness of the scheme is sustained through wider national and international networks: volunteer and paid workers are drawn from several European countries, funding has been acquired from the EU LEADER programme, and internet and transport technologies are essential in connecting with and supplying an international customer base. The broader economy of care instanced in this case study draws attention to a need to develop strategies for sustainable farmland management constructed around wider programmes of social, economic and cultural, as well as environmental, concern.     

Where the buffalo roam: Boundaries and the politics of scale in the yellowstone region

For more than twenty years, the state of Montana has pursued a controversial policy of lethal control to manage winter migrations of bison from Yellowstone National Park. In the late 1990s, as the state and a number of federal agencies attempted to cooperatively outline a more palatable scenario for bison management, local environmental groups became active participants in the debate. This paper examines the strategies pursued by these organizations in the course of their attempt to construct a new, ecosystem-level territorial space and jurisdictional scale for bison, and places their struggle within the context of existing work in geography on the politics of scale. Ultimately, the failure of their efforts illustrates some of the important constraints faced by social groups that attempt to create new territorial regimes and new scales of resistance in the interstices of existing political structures.     

A paper with an interest in rhythm

This paper is a performative effort to move with and through the expressive and theoretical spaces of an interest in rhythm. This interest emerges initially from the middle of an encounter with the 5 Rhythms™, a contemporary somatic practice that uses rhythm to facilitate and catalyse expressive movement. Rather than seeking to excavate representational meaning from an encounter with the practice or using it to critically diagnose the corporeal politics of contemporary society, this paper apprehends the creative movement emerging from an encounter with/in the non-representational, performative potential of the 5 Rhythms™. By becoming a deliberately playful effort to hold onto the lines of movement emergent from the affective, kinaesthetic territories of this practice, the paper works to avoid either falling back upon a representational ethics that stops this movement dead in its tracks or becoming seduced by an aesthetics of weightless escape. This effort draws particular support from Deleuze and Guattari's writing on the refrain, a concept that provides a vehicle through which the lines of an interest in rhythm gain expressive and theoretical consistency. Because the territories of the refrain open onto lines of movement that are as much figural as discursive, the paper works to animate the lines of movement emerging from an encounter with the 5 Rhythms™ through a series of non-representational diagrammatic interventions. Finally, in drawing the diagrammatic lines of this movement in-between, the paper becomes not so much a series of lines about moving, but a series of lines moving about.

RURAL PLACE ATTACHMENT IN HISPANO URBAN CENTERS*

ABSTRACT. Continued rural‐to‐urban migration has helped motivate cultural geographers, long suspected of having a rural bias, to include urban areas in their purview. Patterns of gender, class, ethnicity, and commercialization have proved to be fertile subjects for research, but the elastic links between rural and urban places are not yet well understood. Hispanos, despite intense feelings of loyalty to their rural villages, moved en masse to cities in the 1940s. By the 1950s a majority of Hispanos were living in regional urban centers of the upper Rio Grande country, where wages were higher and employment was secure. This Hispano experience is a crucible for examining how urbanites' attachment to rural places is manifested in various cultural expressions brought from country to city: painted murals, burial preferences, popular music, and irrigation ditches. Understanding threads of rural culture that have been incorporated into the urban fabric in turn leads to clearer comprehension of the emotional attachment that urbanites have for rural areas and a better appreciation of the complexity of the urban cultural environment.
