Water for Agriculture
Potential
study areas are identified and assessed for suitability through Aerial Photo
Interpretation (API) and remote sensing. Ground geophysical investigations are
performed to locate suitable borehole or well positions on site. Various
geophysical methods are employed depending on the site-specific geology and
conditions. Catchment yield potential is evaluated through reserve calculations
to determine the sustainability of groundwater abstraction.
During its
30 years of operation in Africa, GCS has established a comprehensive list of
drilling and aquifer test contractors who can be employed to install and equip
the boreholes. Once installed, aquifer tests can be performed to determine the
sustainable yield of the aquifers. GCS performs drilling and aquifer test
supervision to ensure optimal design, construction, and data collection.
Hydrochemistry is determined to ensure water quality suitability for the
intended use.
Agricultural
studies allow for the integration of water (surface and groundwater), soils and
the environment. With GCS’ strong background in these sectors, GCS specialists
can offer a wide range of expertise to the agricultural sector. GCS has an
established history of providing specialist inputs that facilitate a range of
developments and the specialist skills required for this work can be and have
been effectively applied to Agricultural projects.
Irrigation
is a good example of an integrated application of the soils and water spheres.
This is especially true for the direction in which agriculture is heading;
precision agriculture. There is a drive toward more cost-effectively managed
agricultural resources by better understanding one’s available water and soil
resources. GCS has considerable experience in the development and management of
groundwater resources in Africa and offers the following professional services:
