چکیده
After recovering from the Rwanda Genocide in last century, is experiencing rapid economic growth and urban expansion. With increasing demand for electricity a strong desire to achieve Sustainable Development Goals (SDGs), it significant further investigate electrification progress Rwanda. This study analyzes characteristics of 2012 2020 using VIIRS nighttime light imagery. Firstly, by analysis change patterns on national scale, we find that seriously unbalanced, as Kigali much faster than rest country. Secondly, there common phenomenon where power grid expansion fails keep pace with urbanization, especially areas an inadequate infrastructure foundation. Quantitatively, original level shows positive impact access new settlements, R2 value 0.695 linear regression. In addition, settlements inside boundary tend more extensive compared those outside boundary. Finally, rates are calculated multi-spatial scales. By comparing results official rate data, analyze development off-grid The imply that, since 2016, has rapidly developed Rwanda, rural areas, playing important role achieving SDGs.

Zimbabwe’s economy declined between 2000 and 2009. This study detects the economic decline in different regions of Zimbabwe using nighttime light imagery from the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS). We found a good correlation (coefficient = 0.7361) between Zimbabwe’s total nighttime light (TNL) and Gross Domestic Product (GDP) for the period 1992 ...
