ABSTRACT: This paper analyzed and mapped the impact of built environment (BE) on
socio-ecological services along Dar es Salaam metropolitan coastline. In the
period of 1995-2016,
burgeoning population exacerbated high rate of construction processes and
activities. Such anthropic initiatives affect the benefits and values delivered
by landscape wetlands, estuaries, beach areas, open space and greenery patches
in Dar es Salaam coastline. Motivated to understanding socio-ecological impacts
(SEIs) of BE along the coastline; the study applied focus group discussions
(FGDs) method to identify SEIs, and their category as either positive or
negative. Using analytical hierarchy process (AHP) generated weight to each
SEIs; thereafter combined that weight with landuse landcover (LULC) change
statistics of each of the 67 wards involved in the study. Mapping results of geographically weighted regression and inverse
distance weighting (IDW) interpolation (ArcMap v10.3) displayed the
variables relationship magnitudes and
distribution in positive and negative SEIs for year 1995, 2005 and 2016.
