TIGER-BRIDGE to continue activities for users in Africa

The aim of the TIGER Bridge project, which is financed by ESA and was started in December 2015, is the continuation of TIGER NET efforts strengthening the EO capacity and knowledge within the African water resource community. This explicitly refers to the antecedent efforts of ESA in this field, which established and developed a TIGER community in the African water sector which plays more and more the role of catalyst in technology transfer and knowledge development for the application of Earth Observation (EO) as e.g. provided by the ESA Sentinel missions.
The antecedent efforts have two major results: an ever increasing community which is becoming an active key player of the applications of EO in the water sector, and the knowledge base, in a certain sense a “TIGER culture”

Application of Sentinel 1 data to capture floods in Malawi and Mozambique

Heavy rains following cyclone Bansi have caused devastating floods in Southern Malawi and central Mozambique along the Shire, an important tributary to the Zambezi River. According to sources in Malawi the floods are the worst in more than 20 years resulting in more than 200 deaths, massive destruction of infrastructure and agricultural fields as well as raising fears of a large-scale cholera outbreak.

The Zambezi river basin experiences a number of natural disasters with floods being the most devastating. There is great need to reduce and manage the risk of the effects of such natural disasters, because they leave a trail of destruction that disrupts peoples’ livelihood and the economic growth in the basin and the southern African region as a whole.

It is for this reason that the floods in Malawi and Mozambique are being monitored closely by the newly established permanent Zambezi Watercourse Commission (ZAMCOM) Secretariat through the use of the Water Observation and Information System (WOIS) where free radar satellite images from the Copernicus Sentinel-1 mission are being converted into maps showing the development and current extent of the floods.

The information gathered is important to better assess the flood situation in the development of an operational flood forecasting tool for the organisation. With this system ZAMCOM will be able to predict water levels and possible floods in advance using state-of-the-art modelling tools.

As Professor Zeb Phiri, the Executive Secretary of the ZAMCOM Secretariat explains: “Disaster risk reduction and management is a cornerstone of the ZAMCOM agreement and the flood maps derived from WOIS make an important contribution to the current enhancement of the Zambezi Water Information System (ZAMWIS) and towards the implementation of a fully operational Decision Support Systems for flood forecasting and early warning in the Zambezi river basin”.

In Malawi, heavy rains returned over the weekend and the space based monitoring of the flood situation will therefore continue over the coming days and weeks. Radar satellite images allow following the flooding event independent of weather and clouds, which is why the open and free data of the Sentinel-1 mission is essential for water authorities for their monitoring purposes.

TIGER NET at the 9th international conference AARSE

At the African Association of Remote Sensing of the Environment (AARSE) conference in Morocco, ESA participated with two special sessions dedicated to the TIGER initiative.

The TIGER NET project itself was highlighted both in the special session as well as in the ESA keynote given in the plenary. The response from the African scientific community was very positive to different capacity building activities within TIGER and lead to an official recognition and support in the official AARSE 2012 Declaration. The TIGER NET project has been widely seen as an important activity to prepare for the up-take of the Sentinel missions.

TIGER in Africa and the AARSE 2012 Declaration:

  1. Recognising the importance and success of continued long term collaboration between European Space Agency and African scientists within the TIGER initiative on Earth Observation techniques related to water resources management.
