One of the biggest issues we are trying to address with Bustan Qaraaqa is that of water security. This is valid not only for the West Bank but everywhere as global precipitation patterns change in distribution, intensity or just stop altogether. The site we have is actually a powerful tool as we are located in the lee of the ridge line occupied by Bethlehem and Jerusalem. So we get little rainfall here even compared with sites less than 10 miles away: Beit Sahour is nicknamed ‘little Jericho’ as testament to its dryness and heat. Although it’s not an ideal site for farming, it is an ideal site for establishing techniques for ‘worst-case scenario’ conditions.
As the planet warms and the Hadley cells elongate (http://www.newscientist.com/article/dn9229-global-warming-stretches-subtropical-boundaries.html), these kind of conditions will become far more widespread and people will be forced to migrate or find coping mechanisms. We are ideally placed to pre-empt this and to try and find workable solutions.
The practical actions we can take are re-foresting the area, increasing the water-holding capacity of the soil, selecting drought tolerant plants and rainwater harvesting - the latter of which we have been working furiously towards.
At the head of the land, down in the olive grove, we selected a site to build a water storage cistern. Generally only the richer Palestinians can afford to build them. We were looking for cheaper means than the concrete pouring that is generally employed these days as not only is this an ecologically unsound method, the costs are pretty prohibitive. We had 2 alternatives to produce a genuinely water-tight structure: traditional stone-building (dry stone walling in the middle-east) with a lime-skim or a concrete-skimmed breezeblock structure. We opted for the latter due to time constraints.
In the summer, work started aiming to be finished in time for the rains. There was much whip-cracking as unfortunate volunteers were worked mercilessly digging a hole to place the cistern. Thankfully a neighbour took pity and bought along a tractor to finish things off saving the staff and volunteers from a sweaty death. Left with a pit, Alice was promptly thrown into it by a malevolent olive tree during the olive harvest and was rushed to an exciting interaction with Bethlehem’s doctors.
So, yes. Annoyingly we missed the rains. It is still worth us filling it from the mains. Although this isn’t the rainwater-capture we had hoped for, we have a lot of trees that need irrigating and the mains are getting less and less generous. We also plan to keep Tilapia in the cistern as a source of dietary protein for ourselves and a nitrogen source for the trees. Additionally, we didn’t use the most sustainable and cheapest method. However, as they say ‘time is money’ and as there are only 3 full-time staff here we couldn’t afford to spend all our time scouring for rocks and carrying them around. However, the breezeblocks that we used massively decreased the quantity of concrete used. So we saved 12,000 shekels from the 20,000 shekel estimate for a fully concrete structure and the accompanying ecological impact.
Thanks again to all those who put so much literal blood and sweat into creating the cistern!
