I am working as a consulting arborist in the UAE for a couple of large projects.  Whilst there, I have been observing the broad state of the art and there is a long way to go in bringing across current best practice to the Middle-East, and I suspect that is so for many parts of the Middle-East and Asia.  Even in my village in Sussex, in the last month tree butchery has occurred, so the UK still doesn’t always get it right, despite a long tradition of arboriculture.

I have always worked in accordance with the advise given by Dr. Alex Shigo, of the US Forest Service.  His investigations revolutionised our understanding of the way trees react to injury, and this should inform the inquiring arborist.  Sadly not everyone inquires.

Back to trees in the UAE.  What I am seeing is a gradual awakening of interest in the care of trees, and the acknowledgement of the skills needed to carry out that work.  It seems that as more emphasis is put on landscape and more trees are planted, there comes a point when caring for them becomes a higher priority.  This needs to go right across the board, to include the correct pruning in the nursery, this can save many years of bad growth habit, which is not always correctable later.  Prevention is always better than cure. Perhaps the UAE, and especially Dubai, is maturing to the point of switching from development to maintenance. That’s as true for arboriculture as it is for plumbing and building maintenance.

A part of my contracted work is to train local teams in the correct methods of pruning. Basic techniques can be taught, but in the UK it takes three years to train an arborist, so we have to be realistic in what we can achieve. I think it won’t be long before I have UK based arborists over there caring for trees. With the 2020 World Expo now secured, the demand for trees can only grow, whilst in Abu Dhabi a new law requires 25% of all ground space on a development to be landscaped – the demand for beautiful trees has never been greater, nor the need of skilled care more evident.

Here are some pics from my garden; they tell of Nature’s rhythms and how they effect our lives…

I’ve been reading several websites by visionary developers in Azerbaijan, who are proposing some massive Dubai-style developments to the Bay area of Baku, the country’s capital. One, the http://khazarislands.com/ seems like an ambitious Dubai-competitor, an ultra-sleek development on up to 30 artificial islands (think the Palm Jumeirah), the other is based on an existing island and whilst just as pretentious,  http://www.ziraisland.com/ at least aims to generate all its own energy from renewables, and to be carbon-neutral.

The buildings are all based on the forms of nine iconic mountains in the Caucasus Range.  Actually, not a bad idea from the point of view of seismic safety and thermal efficiency etc.  Serious plans to make a huge modern metropolis that is self-sufficient are rare, with perhaps only the Chinese actually trying this with some of their Eco-Cities.

What is needed is to develop a coherent urban greening policy to integrate technologies like living walls and urban tree planting and care, with a carefully thought out irrigation policy.  People still don’t see how essential green walls will be in integrating ecosystem services into a buildings basic functionality, but it will come.  Let’s watch with interest.
