Geoinformation Management
Question 1
GMN621S
1.1. Describe the importance of a problem tree analysis.
(2)
1.2. There are six (6) main steps involved in the formation of a problem tree hierarchy. List
these six steps.
(6)
1.3. Namibia is considered one of the driest countries in Sub-Saharan Africa, with 92% of its
land classified as semi-arid, and dry. Land degradation is a severe concern in the
country, a situation exacerbated by climate change (Chioreso & Begbie-Clench, 2015).
The causes of this problem have been researched and debated for a long time. You are
part of the team that is conducting a desktop analysis to determine the causes of this
problem.
a) Develop a problem tree that depicts the major problem and three main causes, and
for each of the main reasons/causes, identify two sub-causes (second level) for land
degradation.
{10)
b) Formulate a Logic Framework matrix for land degradation using the template below
as guidance and populate the various sections. Redraw the template in your answer
sheet.
