Re: new publication: Assessing and forecasting groundwater development costs in Sub-Saharan Africa

Dear Elisabeth,
thank you for sharing this information on the publication from Xenarios and Pavelic.
Comparing costs for developing groundwater resources in different countries and consideration of the cost barriers to a safer water supply is an important topic, which is not widely published with useful quantitative data.
I can also recommend Paul Pavelic´s earlier work on managed aquifer recharge, a good introduction is available at:
www.nwc.gov.au/__data/assets/pdf_file/00..._completeREPLACE.pdf

Deaar Mohammad dear others,
You are raising important questions for groundwater management and as a hygrogeologist i agree that this worth discussing. However, I u understand that in SuSanA we are asked to focus on the links between Sanitation and Groundwater, e.g.:
1. Planning of sanitation systems which do not contaminate groundwater bodies
2. Planning of groundwater based water supplied which are not at risk from wastewater systems
3. Reuse of (treated) wastewater for managed groundwater recharge (or artificial recharge)

You will find a quite active group in topic 3 also at:
www.iah.org/recharge/

I agree that are certainly a lot more options to implement artificial recharge with stormwater and, where drinking water quality aquifers are not directly at risk, also treated wastewater can be used for artificial recharge.

With regard to questions of overexploitation, intrusion of brackish groundwater etc I am happy to discuss a specific question, but would rather not think that we can cover all the hydrogeology science in this forum.

With best regards,
Leif Wolf

Dear SuSanA Working Group 11 on groundwater issues,

I thought some of you may find the information on this groundwater publication useful (see below).

Regards,
Elisabeth

Dear Colleagues,

Groundwater is the prime water resource in many rural areas on the African continent.

Greater use of groundwater is also a pre-requisite for improved adaptation to the impacts of climate change.

Yet, the costs associated with groundwater development are prohibitively high and poorly defined. A recent study on Assessing and forecasting groundwater development costs in Sub-Saharan Africa (see here aquadoc.typepad.com/files/2852_publ.pdf) identifies
and disaggregates the costs of groundwater development in 11 Sub-Saharan African countries.

Best regards,

[Wg11] WG: Groundwater in Africa

Dear Elisabeth and colleagues in working group 11

Thank you for sending information  ,In  south west Asia  countries such Iran,Afghanistan are rely on ground water as main resources ,unfortunately
annual raining rate decreased in recent years together with  increasing temperature  arose progressively sever drought consequence , extra exploitation of ground water resources without any balance  recharging  for water using replacement cause sever drop aquifers and watershed  level , water quality changing because of  brackish water movement to fresh water aquifer make great concern .
I hope W11 group will move to pay more attention to these concerns and offer some proposals (for example ground water aquifers resources
artificial  recharging)  with bio remediation and other simple practical approach for rural area or small urban communities.

 
With best regards;
