Ecological indicators for climate change

Abstract: The evidence of the effects of human mediated climate change is already evident in most ecosystems. The IPCC projects that there could be as much as a 4˚C increase in global average temperatures by the end of this century. In Mpumalanga the average temperature is projected to increase by as much as 2.8˚C, and annual precipitation levels by as much as 60 mm. Climate change, along with other human mediated factors such as land use changes and the over exploitation of natural resour...

The Significance of Geography on Trade, State Power and Development: Comparative Research on West Africa and East Mediterranean Europe from Eighth to Fifteenth Century

Abstract: The existing historical economic and political accounts of Africa and Europe fails to fully explain the divergence of commerce, state power, and development between the two regions. The patterns of differences in these two regions have far more significant underlying factors. They go beyond historical experiences of Africa's of slavery and slave trade, colonialism and imperialism. The over-emphasis on unique history as the primary cause of the gap in state power and development vei...

Impacts of expansion of agriculture and land use change on flow regime of Thiba river, Kenya

Abstract: Soil and Water Assessment Tool (SWAT) was used to model the impacts of land cover changes on stream flow regime in the Thiba River basin a sub-catchment of Tana River Basin covering a surface area of 1648 km2 in central region of Kenya. The basin is characterized by intensive agricultural activities including the largest rice irrigation scheme in Kenya. A study was undertaken to test the capability of the model in predicting stream flow response under changing land use conditions i...

Assessment of land use and land cover change in Makueni County for selected time periods

Abstract: The surface of the earth is undergoing rapid land use and land cover changes (LULCC) due to various socio-economic activities and natural phenomena. The main aim of this study was to gain a quantitative understanding of LULCC in Makueni County between 2000 and 2016, and analyze the relationship between these changes and their possible underlying drivers in the County.
