O crescimento urbano é um fenómeno mundial. Ocorre rapidamente e consiste na ocupação dos terrenos adjacentes de uma zona urbana e na alteração do padrão de utilização dos solos, das características demográficas e na transformação das actividades económicas da população. Ao longo dos anos, as cidades etíopes têm registado uma enorme expansão, o que suscita uma grande preocupação para os responsáveis pelo planeamento urbano. O presente estudo utilizou tecnologias de Sistema de Informação Geográfica (SIG), Deteção Remota (RS) e Sistema de Posicionamento Global (GPS) para identificar a natureza da expansão física na cidade de Debre Markos entre 1984 e 2012. De acordo com o estudo, a área construída cresceu de 6,78 para 10,93 km2 entre 1984 e 2004 e de 10,93 para 12,76 km2 entre 2004 e 2012. Verifica-se um aumento de 44,04% nos limites entre 1984 e 2012. A cidade invadiu muitas áreas agrícolas e florestais preciosas durante o período de estudo. A fim de acompanhar o crescimento físico das cidades, o investigador recomendou a necessidade de introduzir tecnologias modernas como SIG, RS, GPS e a utilização de técnicas de gestão adequadas pelas autoridades de planeamento urbano.
