Description:
Site selection for aquaculture development is a complex task involving identification of
areas that are economically, socially and environmentally suitable, which can also be
available for aquaculture. Geographic information systems and remote sensing
technologies, which facilitate the integration and analysis of spatial and attribute data
from multiple sources, have been widely used for selecting suitable sites for different
land uses. This study used these technologies to identify sites suitable for aquaculture
development in Embu District and assessed its potential contribution to food security and
economic development in the area. The study developed map-based site selection criteria,
using soil quality, water availability and socio-economic factors. These criteria were then
implemented, aquaculture potential sites identified, the total area estimated and the
economic impact assessed. The study predicted that about 20% (9,563 ha) of the total
arable area of 47,800 ha in Embu District is suitable for aquaculture development. The
study estimates that if aquaculture is optimally combined with other existing land use
activities, it can contribute over Kshs. 9 billion per annum to the district’s revenue.
Comparing this with the current 7 ha under aquaculture, Embu District has potential for
improving its economic status through aquaculture development. The study recommends
that similar studies be carried out throughout the country so as to improve food security
and wealth creation.
