Sand Dams Worldwide is a not for profit organisation that supports rural, dryland communities to work their way out of poverty with dignity. We work with local partners to support communities to build sand dams - the most cost-effective method of catching and storing rainwater in drylands. Sand dams provide safe water for life and the opportunity to grow enough food to eat, store and sell. Sand dams empower communities, putting their future firmly in their own hands.
The need for safe water in drylands:
Over 40% of the earth’s surface consists of drylands (hyper-arid, arid,semi-arid and dry sub-humid areas with concentrated periods of seasonal rainfall). These drylands which cover large areas of Africa and Asia are home to around 2.3 billion people, mostly living in rural poverty trying to eke out a living in a tough climate, typically spending up to 11 hours a day fetching water.
Sand dam success (so far) and Sand Dams Worldwide's vision:
As of 2022, Sand Dams Worldwide had enabled the build of over 1,000 sand dams in 10 countries, providing over 1 million people with access to safe water, and it is Sand Dams Worldwide's vision to enable 1 million sand dams to be built for 0.5 billion people by 2050 (supporting the world’s poorest people to transform their own lives through sand dams, soil and water conservation).
I love all this stuff. A great way to save part of the world.
very nice animation
This sounds great and I'm really happy for the people who profit from it, but I hope you also build more check dams to refill the groundwater? If you teach people to make swales and how to plant vegetation around them the whole area can transform quickly.
These are quicker solutions to stabilize the population’s water needs. The video clearly states after building the dam, the people will have time to do as you stated. Most of these sand dams are built in tribal areas that don’t have fencing and have large grazing wildlife populations that make it difficult to plant anything. Your ignorance of the terrain and wildlife is expected from someone who obviously has never visited these areas. 🙄
One bridge
You’re equally funny showing ignorance assuming simply because they ranch rather than farm means they can’t plant anything.
Of course ranchers or even wildlife owners can plant a designed blended seed crop for the area. Probably a good idea if they can slow down water flow to have plants or seeds there to benefit from it.
Theres tons of different rangeland equipment you can use depending on what you want to do.
swales are good for cooling an area for a special micro-clima. But this Concept saves the water very well from evaporation and fills up the ground water.
These do recharge the groundwater, as there is no seal made on top of the earth behind the dam
will we get any update on this? I'm very interested how's it going on now
Perhaps you could click on the link to their website.
@@Alan_CFA I was thinking more like a video so everyone can see, not just read about it
How long have these dams been around? do we have much long-term data?
Hi there, thank you for your query. Sand dams are an ancient technology, which we at Sand Dams Worldwide have been leading on and enabling since 2002. Our impact report here outlines what we have achieved since 2002: www.sanddamsworldwide.org.uk/FAQs/impact-report-2022
And here are some papers/evidence and research to support our sand dam technology and our work: www.sanddamsworldwide.org.uk/Pages/Category/evidence-and-research
If you have any other queries, please visit our website or email team@sanddamsworldwide.org.uk
if you want a spring, plant an African banyan tree, one spot 3 banyan tree, every 500 meters. Insya Allah the banyan tree is very strong and stores a lot of water so springs appear. and the leaves can be used for animal feed
Fantastic!!!❣️❣️❣️
0:35 первое же действие и с ошибкой. Системы водоудержания начинают строить с верха водозабора, опускаясь вниз
Если построить дамбу посреди бурногл потока вода её смоет, или стомость дамбы будет таковой, что она не оправдает себя экономически
Totally agree, the dam has to be thicker and need material from the surroundings like rocks and heavy dirt.
i saw some videos like these a number of years ago and would love to see updates and how they have impacted the local community. ive heard hence that many silted up and are no longer operaple , is that true .
Hi Allan, thanks for your comment. Since 2002, we have supported the construction of over 1,000 sand dams across 10 countries which are benefiting over 1 million people. These sand dams are still operational, and can last for upwards of 60 years; and along with the virtually zero operation and maintenance costs, it makes them of the most cost-effective, sustainable solutions to water scarcity.

@@sanddamsworldwide Thats great 👍🏼👍🏼 wonderful
😘Good work Aģape 👏
HalleluJah ✅️
I would like to see how it is being built in details

curiously this phenomenon only exists as CGI and not video evidence? Swales, CT, check dams, gabions, boulder dams, etc? "steel reinforced concrete" as "most cost effective" lol

Very interesting to see how a 'silted up dam' still provides a lot of water for people in the community and that the sand filters it so they get acces to cleaner drinking water.
I have been watching a lot of videos on what India is doing in their drylands recently also. They treat the whole watershed to infiltrate as much water as possible as high up in the watershed as possible. So in addition to these dams they also use contour trenches, contour buns, farm buns, valley plugs, gabions, check dams etc. Most of it is pretty low cost and easy to construct by the people themselves.
I guess you already are familiar with this kind of work but if not just in case it might be useful.
What is Watershed development?

アフリカの乾燥が進んでいる国や地域にダムを作るべきです‼️
ケニアのサンブル国立公園、タンザニアのタランギレ国立公園、ルアハ国立公園、カタビ国立公園、ボツワナのチョベ地区、ナミビアやコンゴ、サハラ砂漠等
that's great but what about the men? heard about the women and kids (pretty sure the men would be doing most of that farming XD).
Hi there. Thank you for your query. In many of the regions and communities we work with, families split the daily responsibilities. Traditionally, it is the men who earn the family’s income through going to work, whilst the women will collect water, stay at home, cook and look after the children.
However, sand dams and subsequent climate-smart agriculture empower women, as they become decision makers and leaders in their communities, whilst children (and parents alike) have improved nutrition at school, work and home thanks to the safe water.
The local source of water also vastly reduces the amount of time needed to collect water, giving more time and opportunity for women to develop their own income, and for children to go to school.

@@sanddamsworldwide ah i see. so they still have to go to work on top of all of it. figures. still think it's a great idea though. been thinking about it since last night actually.
not for africa, but in the desert southwest where i live. there's a movement out here to green the desert. shaun atwood has hundreds of acres in the big bend area he's working on.
Why are you excluding men?
Hmmm....I wonder what the men are doing in these communities.
ahahahahah sand dams ahahahhahahahahaa
Is there a particular reason for exluding men and overempathising women in the video?

There is a big movement in Africa to remove all outside influence as they are more than capable of doing things themselves, so no need to ask us then?
Hi there, thank you for your comment. For most of the areas we work in, it is the communities themselves that are responsible for the construction work. Our partners will provide skilled supervision and instruction, but the labour put towards sand dams comes from the communities. This aligns with one of our key values of providing communities with the tools to change their own lives, giving a hand up rather than a handout.
Once a sand dam is complete it is the community’s to own and look after. They are responsible for maintaining them and ensuring that the surrounding area is well looked after. Our partner organisations provide them with all the training that they need in order for this to happen, and for the sand dams to keep supporting the communities for many years.

What is this whoatah you speak of.
What happens to downstream people?
Suffering then 😢
