1 INTEGRATING CLIMATE CHANGE RESPONSES IN THE MASTER PLAN RENEWABLE WATER RESOURCE PLANNING & MANAGEMENT- PRESENTATION TO ICLEI CONFERENCE HELD AT DAR-ES-SALAAM ON 30 TH OCTOBER, BY PLANNER J.K.BARREH, DEPUTY DIRECTOR CITY PLANNING DEPARTMENT:

2 NAIROBI & ADJOINING AREAS

3 NAIROBI MASTER PLAN AREA Size: About KM 2 Day Population About 4.0 millions

4 MASTER PLAN s OBJECTIVES The proposed Nairobi Integrated Urban Development Master Plan (NIUPLAN) aims to: Develop responsive strategies on implementation of sustainable urban development, Incorporate sustainable water & sanitation strategies, among others, in a range of integrated multi-sector development plans. Undertaken SEA process to fast-track prediction of (-ve) environmental effects & formulate responsive mitigation strategies.

5 STRATEGIC ENVIRONMENTAL ASSESSMENT (SEA) Sea is a systematic process for evaluating potential environmental, social and economic impacts of a proposed Master Plan s policies, plans or programs (PPP) to ensure they are fully studied and effectively managed at the earliest stage of planning and decision-making.

6 NIUPLAN & IMPORTANCE OF SEA. As a PPP-the NIUPLAN is being subjected to SEA instead of EIA due to: o Nairobi s Geographical setting and its neighbourhood & context, o Multiple Land uses, e.g, Residential, Commercial, Offices, Airports, Industrial, Physical Infrastructure & Social amenities, etc., o Diverse existing & anticipated interinfrastructural linkages in the proposed master plan E.g. Renewable water resources planning/management.

7 SUMMARY - KEY ISSUES OF SURFACE WATER RESOURCES

8 EXAMPLES OF WATER RESOURCES SUB-SECTOR PLANS Water Infrastructure Plans [among others], Water Supply Master Plan incorporating Underground/Borehole Water, Rain Water Harvesting, Water Re-cycling Plan(s), Riparian Way leaves/riverine Drainage plans, Waste water Disposal Plan, Storm Water Drainage Plan,

9 SURFACE WATER POLLUTION

10 EXAMPLES OF OTHER SECTOR PLANS: Solid Waste Management, Forests, Parks & Recreational Spaces, Renewable Energy & Electric Power, Landscaping Schemes, Environmental Issues, etc.,

11 LAND USE AND ENVIRONMENTAL MANAGEMENT CHALLENGES Conservation of landscape features; Sustainable use of natural water & landscape resources; Conflicts between urban development and conservation of renewable water resources;

12 CONT D. Lack of efficient natural landscape conservation mechanisms & Increased paved areas, inadequate storm water drainage systems - flooding & erosion effects, subsidence &/or landslides, etc., Limited integration between built-up areas & renewable water resources plans-being embraced by the NIUPLAN.

13 INTEGRATING DIVERGENTSECTOR PLANS: onairobi Metro 2030 Strategy ( 2008), owater Supply & Sewerage Master Plan (2012), ostorm Water Drainage Master Plan (2013/14-Underway), etc.,

14 CONT D. o SEA process is being undertaken on the NIUPLAN that comprises of various water resources sub-sector plans derived from various conceptual contexts to be synchronized, o Designing responsive & harmonized mitigation strategies with multiple stakeholders to provide coherent and responsive Environmental Mitigation Plans ( EMPs) on:-

15 CONT D Gray water re-cycling, Rain water harvesting, Re-charge of underground water sources, protection of riparian reserves, Cleaning/purification of polluted rivers/river basins

16 CONT D. o Incorporation of green building concept/zero energy use buildings and o Utilization of renewable water & energy sources in the built-up environment - sustainable development :

17 NAIROBI s FACTS & FIGURES ON GROUND WATER By mid total number of known boreholes within the Nairobi Aquifer system was 3,639 No. with a demand of 800,000m 3 daily. Nairobi & neighbouring counties - gazetted as a ground water conservation area in Studies on aquifers by WRMA (2007) - show underground depletion is a response to excessive abstraction against natural recharge, Abstraction of ground water is active in areas where there is no water supply from the NCWSCo - but boreholes exist in some areas to supplement NCWSCo s supply.

18 NAIROBI s FACTS & FIGURES ON WATER CONT D. Daily demand of wholesome water about 600,000 cubic metres; Daily supply from its 4 No. sources in 3 other Counties 500,000 cubic metres ( 30-40% lost thro leaking & illegal connections); During drier seasons wholesome water supply declines to less than 300,000 cubic metres supplemented vide borehole water.

19 INTEGRATION OF RENEWABLE WATER RESOURCE PLANNING INTEGRATED INTO THE MASTER PLAN PROCESS Use of effective mitigation strategies to forestall the depletion of declining non-renewable water & energy sources, Reducing paved areas/hard landscape & buildings footprints while pursuing more compact developments, Incorporation of efficient water & energy utilization concepts & land use design strategies, Adopt conservation/compatible mixed land use planning interventions for sustainable urban developments, Integrated multi-sector renewable resource use planning.
