“Arab Climate Resilience Initiative” First Regional Consultation Meeting “The Impacts Of Climate Change On ِ WaterResources ” Damascus, The Arab Republic of Syria 15-16 September 2010. Dr. Naif Abu-Lohom Prof. Dr. Abdulla Babaqi Water & Environment Centre (WEC), Sana’a University Republic of Yemen
Contents • Background Information • Yemen’s Climate Change Profile • Challenges in Water Sector • Scenarios of Climate Change Impact on water sector • Main National Policies, Projects, Activities Undertaken to Address CC • Recommendation to Mitigate and adopt with CC Impacts • Opportunities for Interventions at Different Levels: • (Technical, Policy, Institutional, Support of Local Communities, etc)
Background Information • Yemen signed UNFCCC in 1992 and ratified it in May 1996. • Ratified Kyoto Protocol in September 2004. • Established CDM Committee in 2007.
Yemen Climate Change Profile • UNESCO (1979), classified Yemen into 4 Climatic Zones: Hyper- Arid Zone Rainfall < 50 mm/Y Arid Zone (Rainfall = 100 – 250 mm/Y Semi Arid Zone Rainfall = 250 – 500 mm/Y Sub-Humid Zone Rainfall > 500 mm/Y
Yemen Climate Change Profile Temperature Trend • Historical data (since 1970) indicate Warming become greater for summer(+0.2°C/decade) than winter (+0.15°C/decade). • According to IPCC report, Yemen is expected to warm by 3-4°C by 2080s which is roughly 1.5 times the global mean response Rainfall Variability In Yemen • The average total annual precipitation recorded for about 100 years show variability but without an obvious and unpredictable trend • The extreme events are increasingly becoming a source of concern • (Hadramout & AlmahraFloods).
Rainfall Variability In Sana’a City • The Fig. depicts the spatial distribution of rainfall in Sana’a City measured at four stations • It shows significant differences in total rainfall over a period Jan. – July 2007
Hadhramout Flood, 25th October, 2008 • The flooding comes after more than a full day of rain in Yemen, which normally receives only a few inches of rain per year. • A flash floods have claimed the lives of more than 140 persons and left more than 20,000 without shelter in the Hadramout and Maharah Governorates
Vulnerable Sectors to Climate Change Impacts • INC & NAPA identified 5 main sectors vulnerable to climate change • Impacts: • Water Resources • Agriculture • Coastal Zone • Biodiversity • Health and Tourism
Challenges In Water Sector • Increased water scarcity and reduced water quality • Per capita annual water resources of only 120 m3 • 10% of regional average and 2% of global average • Over-exploitation of GW (3-8 meters/year annual drop in most of the basins) • Annual Abstraction in SB exceeds 4 times the recharge • Irrigated area has expanded from 37,000 to about 1,200,000 ha • Agriculture use more than 90 % of Water Resources • Decrease Water Supply in most of the main cities (Sana’a, Taiz,Amran.) • Increase water conflicts. • Low irrigation water use efficiency (20-40%) • Institutional and implementation capacity challenges for groundwater management
Total renewable water: 2.1 Bm3/y. Total water use: 3.0 Bm3/y Deficit: 900 Mm3/y Water status in Yemen • Excessive Pumping • Flood Irrigation • ََِQat trees
Impacts of Climate Change in Groundwater • Three simplified CC scenarios of the impacts of CC on groundwater for the period 2025 up to 2080s were developed (WEC & HR Wallingford, 2010) . This study financed by the World Bank in the framework of NAPA programe: • A “hot and dry” scenario • A “mid” scenario, • A “warm and wet” Scenario • These scenarios were developed based on the collected baseline data (1961-2000) i.e. : • Average annual Temperature • Average annual rainfall • 3. 15 Global Climate Model (GCM)
Scenarios Broad Characterization • Expectations: • - warming (1 to 1.6 °C) • An increase in rainfall • An increase in Runoff and recharge • Expectations: • Considerable warming (1.6 to 3.1 °C) • No significant change in rainfall • Expectations: • Decrease Rainfall, • Decline of runoff and recharge • Temp. may become too high (2 to 4.5 °C) Change in annual rainfall % Warming Degree C
Prospects of GW Abstraction & Climate Change impacts for Yemen as a Whole By 2025 GW reserves will be exhausted & abstraction will equal recharge After 2025, the GLshows the extraction levels that would be consistent with current rates of recharge + the extra resource available from increased recharge under the ‘warm & wet’ scenario. The Red Line is common to all scenarios up to 2025 The RL after 2025 traces: Drop in recharge & abstractions below current recharge levels under Hot & Dry Scenario Average GW Recharge Baseline
Main National Policies Undertaken to Address the CC • The Initial National Communication (INC) on CC was prepared on April, 2001 • The National Adaptation Programme of Action (NAPA, Yemen) was prepared on 2008 and endorsed by Cabinet in March 2009. • The Second National Communication (SNC) on CC was prepared on 2007- 09. • Some Relevant Existing national and sectoral strategies and plans • Poverty Reduction Strategy, Vision 2025. • National Water Sector Strategy and Investment Programme (NWSSIP) • Integrated Coastal Zone Management Plans • Health and Environment Strategy • Environmental Impact Assessment Policy • World Bank Country Assistance Strategy (CAS) • Establishment of Inter-ministerial CC Commission/Board, 2009: • (MWE, MAI, MoF, MLA, MFW, MoT, MTIT, EPA, NWRA)
Previous Projects Related to CC • - National Level: • A Study on climate change scenarios projections (2008/09) • National Capacity Self Assessment for climate change, biodiversity and combating desertification • National Probabilistic Risks Assessment • Hadramout and Al Mahra Probabilistic Risks Assessment • - Local Level: • Municipality of Sana’a Natural Disaster Risk Evaluation and Urban Planning • Sana’a Integrated Storm water Management Plan • Adapting to Water Scarcity for Yemen’s Vulnerable Communities: • (Case studies of Sana'a Basin , Sada’a Basin and Aden City)
On-going Projects Related to CC • Climate impacts on water resource management and agriculture (W. Bank) • Climate impacts on Agrobiodiversity (World Bank) • Rainfed Areas Livestock Project • Agro-biodiversity and Adaptation Project • Water Sector Support Program • Groundwater and Soil Conservation Project (World Bank) • Sana’a Basin Water Management Project • Integrated Coastal Zone Management • Irrigation Improvement Project Planned Projects Related to CC • Pilot Project for Climate Resilience (PPCR)
Recommendations to Mitigate and Adopt with Climate Change Impacts • Improving governance through transparency and an active civil society role, • Capacity Building and awareness Programme at all levels • Empowering rural communities so that they can participate in assessments and feed in their knowledge to provide useful climate information; • Integrate climate resilience into the design of new infrastructure for irrigation and flood control • Developing an early warning systems which can help to anticipate and prevent disasters • Integrating climate change impacts into economic planning for the national budget.
The opportunities for interventions 1. Technical Opportunities : WR management and agriculture • Updating knowledge on critical basins to determine safe yields and storage capacities of aquifers and surface water resources. • Upgrading the network of hydro-meteorological monitoring stations; collating relevant agricultural, social and economic datasets to enhance understanding of the system • Developing and use appropriate tools such as Decision Support System DSS at different levels (Catchment, Basin, County) • Developing robust climate models that reduce the degree of uncertainty in national and regional climate prediction. • Conducting Remote sensing and ground-truthing studies to identify the relationship between climate and change in water resources, food security and agriculture.
The opportunities for interventions 1. Technical Opportunities : WR management and Agriculture
The opportunities for interventions 2. Policies, Institutional and Capacity Building: • Establishing a CC strategy endorsed by Cabinet and in consistence with available strategies • Accelerating formation of National Committee for CC adaptationand representing all concern agencies • Mainstreaming of climate change issues into all local, sub – national, national, and sectorial planning processes • Building institutional and technical capacity in the MWE, including NWRA, the water utilities and GARWSP to better integrate climate change concerns into water strategies and policies. • Ensuring close cooperation among various agencies with interests in the water sector, including MAI, MWE, NWRA, EPA, the water utilities, GARWSP, and CAMA. • Revision and development of Water Resources plans according to CC impacts • Staff Capacity Building and provision of a suitable environment to perform their tasks
