Key argument
The Eastern Africa sub-region is one of
the most vulnerable regions to impacts
of climate change, but with
considerable potential to minimise the
effects of such changes through the
deployment of innovative institutions
Structure of the presentation

About ASARECA
ASARECA: Established 1994 as a not
for profit sub-regional research
organisation comprised of 11 member
countries: Burundi, D.R. Congo, Eritrea,
Ethiopia, Madagascar, Kenya, Rwanda,
South Sudan, Sudan, Tanzania Uganda.
Mission: To enhance regional collective
action in:
Agricultural research for dvepment,
Extension and
Agricultural training and education
To promote:
Economic growth,
Reduction of poverty and hunger
Enhance sustainable use of resources
in ECA.
Climate Smart Agriculture: New paradigm for African agriculture?
Based on the challenges and existing opportunities,
agriculture must be transformed to feed the increasing
population & provide the basis for economic growth and
poverty reduction
Agricultural productivity – climate change nexus
(transition to agricultural production systems that are):
①More productive
② Use inputs more
efficiently
③More resilient to risks &
shocks
① Enhance food security
& nutrition
②Mitigate climate change
③ Conservation of natural
capital & sustain the
flow of vital ecosystem
services
Forest loss and hence loss of key ecosystem services
Ethiopia - Between 1990
and 2005, the country
lost 14% of its forests or
21,000 km²
Kenya - in 1963, forest
covered 10% of land in
Kenya and by 2006 that
dropped to 1.7%
Tanzania - between 1990
and 2005 an estimated
412,000 ha/yr were
cleared, i.e., about 1.1%
of the total forest area

Melting of Mt. Kilimanjaro glaciers
An estimated 82 % of the icecap
that covered Mt Kilimanjaro
surveyed in 1912 is now gone.
According to some projections, if
the recession continues at the
present rate, the majority of the
glaciers on Kilimanjaro could
vanish in the next 15 years

Strategic areas of intervention to minimise
climate-induced impacts
Creation of knowledge and information hub on
climatic conditions – long-term & downscaled
Enhanced application of ICT in dissemination of
seasonal and climate information
Establishment of learning platforms across
borders
Promotion of market-lead innovations for the
diversification of livelihoods
Sustainable management of ecosystems
Efficient use of agricultural water (AW
productivity) & intensification of ISFM
ASARECA Interventions in the sub-region
1. Improving agricultural water productivity, ISFM
2. Crop-livestock integration
3. Sustainable agricultural intensification
4. Promotion of CA
5. Use of ICT in disseminating seasonal information
Community-Based Integrated Watershed Management
Afforestation with multi-purpose trees
Community mobilization
Trenches to control runoff
Water and soil conservation technologies

3. Climate Smart Technologies Promoted
Promoted rainwater water harvesting
and storage into underground tanks
Stored water used for market oriented
vegetable production under drip
irrigation. Water pumped using gender
friendly treadle after modification by
ASARECA
Promoted drought resistant Brachiaria
mulato and Panicum maximum to
sustain dairy production
Disseminated Napier grass production
under semi-arid conditions using the
“Tumbukiza technique”.
Impact CSA Agriculture promoted at 512 households
in Kenya, Uganda, Tanzania and Burundi.
Through projects interventions, fodder
availability increased by 76%; milk yield by
78.7% and average cash income by 52.3%.
Yield of Napier under Tumbukiza increased
from 3t ha-1 to 6.9t ha-1 (230% increment).
Forage seed and B.mulato planting material
brought a net income of US $ 1,360 per acre
per year in Uganda
Promotion of striga resistant sorghum varieties
High yield: Striga resistant Zero yield: Susceptible variety
SUSTAINABLE INTENSIFICATION OF SORGHUM –LEGUME SYSTEM TO IMPROVE LIVELIHOOD AND ADAPTATION TO CLIMATE CHANGE IN ECA
Sorghum (SESO3 in a farmers’ field)
Sorghum-cowpea products
Pearl millet innovations for improved
livelihoods in drought-prone areas of
Eastern and Central Africa (ECA)
Success factors
1) Use of innovation & learning platforms to facilitate
interaction among stakeholders along the value
chain
2) Capacity strengthening of pastoralists and communities to enhance adoption and utilization of TIMPs - working with communities to strengthen local governance/institutional systems
3) Market/incentive driven approach
Working towards improving market access
Enhancing competitiveness of the target VCs
Demonstrating the value of environmental conservation in
community livelihoods
Brighter side of African agriculture
4 of the world’s 30 fastest growing economies are in ECA
sub-region (IMF World Economic Outlook)
Rwanda – 7.7 (14)
D. R Congo - 7.1 (21)
Ethiopia - 7.0 (23)
Tanzania - 6.5 (29)
Africa is a new frontier for agricultural expansion –
opening up new areas, sustainable intensification,
adoption of efficient technologies, shift to irrigated &
mechanised agriculture, growing political support to
agriculture & investment in climate smart agriculture
Opportunities for fast-tracking adoption of CSA
Diversity of existing institutional frameworks for
cooperation (local, national and sub-regional)
Increasing interest and support in CSA and
Market integration across the sub-region –
hence expanding market for CSA-based value
chains
Challenge: How to shift away from piece meal,
project-oriented and externally supported
initiatives
