Background

The Greater Horn of Africa region is a land of contrasts. If you look at the two most common hazards in the region notably droughts and floods, they are characterized by severe shortage or excess rainfall, respectively. Disasters pose multifaceted challenges in our region. Drought, for instance, is a phenomenon that not only puts the lives and livelihoods of the communities in the region at risk but also destroys the hard-earned development gains of communities and countries at large. The resources that countries are investing for years in drought disaster response and recovery could have significant contributions to advance sustainable development. There is a strong need to put in place all the necessary mechanisms to prepare for and respond to disaster risks. Understanding hazards/risk and putting in place monitoring and early warning systems goes a long way towards ensuring Greater Horn of Africa countries better prepare for and mitigate the adverse effects of disasters. 

Event Objectives

This training is organized with the objective of strengthening the capacity of national DRM institutions and relevant sector ministries through technical training on hazard assessment, monitoring, and early warning. Such technical training sessions provide a platform for sharing good practices in DRM practices among member states. In this five day course, participants will experience hands-on training and also get an opportunity to discuss recent methods and tools in hazard assessment which are believed to strengthen national efforts in disaster risk reduction.

Learning Objectives

  • Recall which earth observation (satellite) products are freely available
  • Use remote sensing  and GIS tools for hazard assesment, monitoring and early warning for disaster risk reduction
  • Describe global and regional approaches and methods used to asses hazards.

Methodology

The course is designed to offer a balanced approach between theoretical and practical methodologies, which will enable the participants to gain maximum knowledge on the subject. It will be taught in lecture/discussion formats illustrated with Power Point presentations, live demos, videos, maps, diagrams, field visits, interactive sessions and content on web sites. Prior skills in Remote sensing and GIS are highly desirable.

The tools will include ArcGIS software for GIS and Remote sensing and Snap tool for flood and drought modelling.
