Outline

1. Hydrogeology and International Development

2. Hydrogeologists Without Borders

Problem statement: Major efforts to provide improved water supply

in developing countries are thwarted and often fail because of the inability to find, develop and sustain groundwater resources.

The field of hydrogeology is not “well”-integrated into international

development efforts

What is hydrogeology?

Geological mapping

Drilling & instrumentation

Field measurements &

gw sampling

Lab analyses & interpretation

Hydrogeological expertise is the integrated knowledge of geology, groundwater flow, natural groundwater chemistry and contamination

towards the sustainable extraction of good quality groundwater resources within the constraints of the hydrologic cycle

How does water fit into ‘International Development’?

‘Watsan, or WASH ‘

How does hydrogeology fit into the ‘Water and Sanitation’ Sector?

Hydrogeology fits into most, if not all, of these core activities…..

• 50 % of potable water supplies

• 40 % of self-supplied industry

• 20 % of irrigated agriculture.

UNESCO (2003)

Worldwide Groundwater Use

• Drought or dry season resistant

• Close to the point of demand

• Excellent natural quality

• Can be developed incrementally

• Technology simple

• Naturally protected fromcontamination

Why Groundwater?

• often polluted near where we need them• usually fully or nearly-fully exploited• unreliable seasonally • highly impacted by storm events

The Problem with Surface Water

‘A spectacular increase in groundwater development for irrigation has taken place during the last half century in

most arid and semiarid countries: a kind of Silent Revolution, carried out mostly by the personal initiative of

millions of modest farmers in pursuit of the significant short-term benefits groundwater usually triggers.’

UNESCO (2006) estimates that half the world’s megacities and hundreds of other major cities on all continents rely upon or make significant use of groundwater.

Reliance of Megacities on Groundwater

Groundwater for Potable Water Supply in Africa

Algeria: > 60%

Libya: 95%

Mauritania: 80%

Nigeria: > 90%

South Africa: 65%

Ghana: 80% Over 75% of improved village and small town (i.e. rural) water supplies in sub-Sahara Africa are supplied by groundwater.

Why the increase in groundwater pumpage?

Vision

A world where groundwater is developed and sustainably managed for community water supplies

Mission

Hydrogeologists Without Borders builds capacity in

emerging regions to provide safe, sustainable water supplies

HWB is NOT another organization drilling community water wells

ratherHWB wants to FACILITATE and give ADDED VALUE to the water and sanitation sector

through CAPACITY BUILDING

Goal 1

Establish HWB as the “go-to portal” for practitioners on best practices for groundwater development & sustainability

Goal 2

Facilitate the creation of a growing pool of professional and technical hydrogeologists in regions of critical need.

Goal 3

Facilitate increased application of sound hydrogeological principles and practices in aid and development programs

Goal 4

Establish HWB as a valued partner and leader in international networks of organizations engaged in developing safe sustainable community water supplies

Goal 5

Ensure that HWB maintains ongoing financial resources necessary to deliver on its mission

Student Fellowship• For hydrogeology graduate students studying

in programs in emerging regions • For thesis research expenses• Students submit application packages to HWB

2012 Fellowships awarded to:

How you can get involved

Make a regular financial contribution to HWB via Canada Helps

Volunteer with HWB

How can your organization get involved?

• Directly support an Executive Director to take HWB ‘to the next level’

• Fund development of appropriate capacity building materials (e.g. wikipedia-type groundwater textbook)

• Sponsor (and mentor) an HWB student fellowship• Sponsor (and mentor) an HWB Chair at a partner

university
