  1. 16. An exploratory study of Middle Stone Age and Later Stone Age site locations in Kenya’s Central Rift Valley using landscape analysis : a GIS approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Angela Kabiru; [2017]
    Keywords : geography; geographical information systems; archaeology; Kenya; Central Rift Valley; landscape analysis; Middle Stone Age; Later Stone Age; Earth and Environmental Sciences;

    Abstract : The Kenyan central rift has witnessed dramatic climatic changes over relatively short periods of time in response to global climatic changes, with the water levels of the lakes within the rift rising and falling with these changing conditions. There is considerable evidence showing extreme wet and dry phases throughout their existence. READ MORE

  2. 17. Identifying potential critical transitions in a forest ecosystem using satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Krishna Lamsal; [2017]
    Keywords : early warning; critical transition; tipping point; EVI; time series; GEM; Earth and Environmental Sciences;

    Abstract : Ecosystems can undergo changes that are slow and gradual, or an abrupt change - a sudden nonlinear dynamics that can bring catastrophic changes and ultimately leads to the change in the structure and functioning. Non-linear and discontinuous changes sometimes may cause the system to shift into another undesirable state, called ‘regime shifts’ or ‘critical transition’. READ MORE

  3. 18. Investigating the spatial patterns and climate dependency of Tick-Borne Encephalitis in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Elisabeth Farrington; [2017]
    Keywords : Physical Geography and Ecosystem Science; Tick-Borne Encephalitis; TBE; Sweden; Climate Change; Spatial Patterns; Earth and Environmental Sciences;

    Abstract : The increasing prevalence of Tick-Borne Encephalitis (TBE) in Sweden is a cause of concern to both individuals and the public health service. The disease is spread via bites from the vector Ixodes ricinus and causes long-term neurological damage in 46% of cases. READ MORE

  4. 19. Education and Development : A spatial-econometric approach on spatial change and permanence in southern Brazil

    University essay from Stockholms universitet/Kulturgeografiska institutionen

    Author : Vinícius Floriani Martins; [2016]
    Keywords : education; development; exploratory spatial data analysis; spatial econometrics; path dependence; Brazil; Paraná.;

    Abstract : The Brazilian state of Paraná exhibits a violent geography of inequality and duality, hosting both the most developed city in the country, internationally recognized by its urban and environmental innovations, and southern Brazil’s most concentrated cluster of poverty and underdevelopment. Over the course of the past decades, the state underwent a major economic transformation, modernizing and increasing its industrial structure and shifting to the service sector with a larger participation of the knowledge economy.

  5. 20. Exploring the spatial relationship between NDVI and rainfall in the semi-arid Sahel with geographically weighted regression

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stefanos Georganos; [2016]
    Keywords : geomatics; rainfall; Sahel; scale dependency; non-stationarity; physical geography and ecosystem analysis; geographically weighted regression; Earth and Environmental Sciences;

    Abstract : The Normalized Vegetation Difference Index (NDVI) is frequently used as a surrogate for vegetation properties and is often correlated with climatic variables such as rainfall. However, studies have shown that conventional regression models used to study the spatial relationship between NDVI and rainfall are often plagued by non-stationarity and are scale dependent.
