Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael
Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael
International Journal of Geospatial and Environmental Research
Vegetation Land Cover/Land Use dynamics (VLC/LU) are the result of complex and compound interactions between the human (cultural, socioeconomic, and political) and the physical environment at different spatial scales. The present study assesses the spatial distribution of VLC/LU dynamics from 1987 to 2015 in the North-Eastern highlands of Tanzania using both qualitative (in-depth interviews and focus group discussions) and quantitative techniques (spatio-temporal analysis through GIS). The qualitative approach was used to elicit information on the main drivers of VLC/LU changes by land users as transitions occurred with time. The spatio-temporal analysis was used to assess the systematic vegetation land losses, …

Warmer climates are predicted to increase bark beetle outbreak frequency, severity, and range. Even in favorable climates, however, outbreaks can decelerate due to resource limitation, which necessitates the inclusion of competition for limited resources in analyses of climatic effects on populations. We evaluated several hypotheses of how climate impacts mountain pine beetle reproduction using an extensive 9‐year dataset, in which nearly 10,000 trees were sampled across a region of approximately 90,000 km2, that was recently invaded by the mountain pine beetle in Alberta, Canada. Our analysis supports the hypothesis of a positive effect of warmer winter temperatures on …
