Workshop on the lessons and success stories from a
pilot project on climate change adaptation
interventions in Kabe watershed, south Wollo,
Ethiopia, Addis Ababa, 11-12 February 2013

2. 1. Introduction
 Due to climate change recurrent droughts, erosion and flooding and
drying of streams, springs and lakes appear to be increasing in
Ethiopia.
 To alleviate the problem, the government have given greater
emphasis for watershed based soil and water conservation
(Biological and physical).
 Millions of tree seedlings have been planted by different
afforestation programs in order to improve the environmental
conditions of different areas. However, survival of the seedlings is
not as expected in many of the areas.
 Water stress is one of the major limiting factors, which reduces the
survival rate and productivity of tree seedlings.
 So, there is a need to test different mechanisms to increase
seedling survival such as in-situ moisture conservation and adaptive
species.

3. 2. Methods
Using community mass mobilization and safety net program a
huge soil and water conservation structures were constructed in
the watershed.
Different grass species and multipurpose tree species were
planted on constructed physical structures and on the top of the
watershed (afforestation area).
As a demonstration, 250 seedlings of five tree species were
planted on different in-situ moisture conservation structures.

8. 4. Recommendation
 Greater emphasis should be given to stabilize physical soil and
water conservation structures using biological measures.
 Plantation of seedling integrated with in-situ water harvesting
structures should be strictly followed in the next plantation
season.
 Gully treatment and stabilization should be the first task that we
have to do in the coming season.
