Support to infrastructure

development in SADC

What is CRIDF?

Climate Resilience Infrastructure

Development Facility;

DFID’s new infrastructure support

programme in southern Africa;

Delivering water related infrastructure in SADC

Countries, building climate resilience for the poor;

“Peaceful and climate resilient management of

shared water resources in SADC for the benefit of

the poor.”

In association with;

An introduction to SADCThe Southern African Development Community

15 nation block in southern Africa

- 12 mainland, and 3 island States.

281 million people

Botswana

GDP varies widely – wealthier

south, rapidly developing north.

South Africa’s economy is

2x the rest of SADC combined.

Water in SADC

Rainfall varies widely – from

+2000 mm/a to < 100 mm/a.

15 Transboundary Basins hold 70%of surface waters.

5% of available water used.

Water availability varies over time

and space.

Lead from SADC’s Vision for Infrastructure

Development;

Infrastructure development is seen as a central and key

pillar to SADC’s RSAP III delivering on;

Equitable and sustainable utilisation of water for

social and environmental justice and regional

integration and economic benefits for present and

future generations.

CRIDF Strategy informed by demand

and climate vulnerability context:

Working with SADC and RBOs to respond

to demand for investments;

Differentiating between well watered

(northern) basins and water stressed

(southern) basins;

Pursuing a specific strategy in each basin

–improving climate resilience according

to context;

Zambezi:

Orange:

Small scale storage and irrigation projects;

Enhancing and maintaining natural storage

infrastructure; and

Introducing the ‘water, food, and energy’

nexus in policy.

Stretching available resources further, and

equitable sharing of the saved water; and

Introducing strategic peace dividends into

≈ 280 million m3 at high

assurance (2% of total use)

Water in energy:Move towards sovereign security and

regional surplus through investment in

generation and transmission infrastructure

and bilateral agreements

Provide for growing rural demand through

micro- and mini-hydropower

When water is available ramp down

thermal- and ramp up hydro-power

In drought ramp up thermal- and ramp

down hydro-power.

Water in agricultural products:

Establish variable assurance of supply

based on usufruct rights

Manage energy and irrigation

conjunctively and regionally

For regional companies;;;;

• When water is available ramp up

production

• In drought ramp down production,

and meet demands through regional

trading
