Cities, Biocapacity, and Trade: The Case of Ma’rib

Karim Elgendy

Human settlements have traditionally needed an environmental rationale to exist where they do. They needed access to freshwater and to ecosystems that have enough biocapacity to produce biological materials to sustain their residents. Settlements also required a climate that was moderate enough – or can be economically moderated – to support human habitation.

But for these settlements to become thriving cities, the prerequisites above were not enough. Successful cities depended to a large extent on their integration into an efficient trade network.

One historic regional example of this is the rise and fall of the city of Ma’rib, which is today a settlement of less than 20,000 people just 75 miles east of the Yemeni capital Sana’a, but for almost a millennium, was one of the region’s greatest cities.

Cities of the West Bank

Karim Elgendy

Most cities have a good reason for being located where they are. The major Palestinian cities of the WestBank are excellent regional examples of rational city location. The old cities of JerusalemHebronBethlehem, RamallahJenin, and Nablus are all located on the flat ridges of the West Bank mountain range, benefiting from mild climate and significant rainfall – unlike locations only 15 miles to the east such as the oasis city of Jericho.

Settling along the shores of the gulf

In the barren deserts of the Arabian Peninsula, people have always settled in locations that provided freshwater and enough natural resources to enable trade and economic development. Human settlements in the southern shores of the Gulf, in what we now know as the United Arab Emirates (UAE), are no exceptions to this.

For the last four centuries, the Bedouins of the Banu Yas tribes have settled a strip of land along the northern edge of the dune fields of the Arabian Peninsula’s Empty Quarter. Drawn to its plentiful ground water resources they established what is now known as the Liwa Oasis and developed date plantations which provided subsistence. But when fresh water was discovered on the Abu Dhabi Island in the late 18th century, Al Bu Falah branch of Banu Yas moved to the coastal location which – in addition to providing fresh water- also allowed them to develop pearling industry and trade.

In the early 19th century, another branch of the Banu Yas, known as Al Bu Falasa, moved from the Abu Dhabi Island to settle near a natural creek 90 miles east of the Abu Dhabi Island. In addition to ground water and pearling, the creek – now known as the Dubai  Creek- allowed the establishment of a port which facilitated trade with neighbors across the gulf and beyond. They quickly established a settlement on the western shore the creek – known later as Bur Dubai – but had to abandon it two decades later and move to the eastern shore after a smallpox outbreak. By the end of the 19th century, the combined advantages of fresh water availability, the natural port, the pearling industry, and the good geographic location, were sufficient for the new settlement to endure a sweeping fire that burnt through most of it dwellings. The Bedouins that have settled in Dubai sought no other location and simply rebuilt their settlement.

Two Unsustainable Urbanisms: Dubai and Gaza

Karim Elgendy and Joumana al Jabri

An infographic comparing the two extreme urbanisms of Dubai and the Gaza Strip. While the two urban regions demonstrate surprising similarities when their geographic and demographic data are compared, their political and socio-economic conditions have produced urbanisms that are radically different and equally unsustainable.

A Visual Guide to Energy Use in Buildings in the Middle East

Karim Elgendy

In celebrating this year’s World Green Building Week, Carboun has released a visual guide to energy use in buildings with the goal of explaining the overall state of energy use in the region and the significance of buildings as a major sector in energy consumption. It also aims to comparatively explain the nuances of the major trends of energy use in buildings as a baseline analysis for further research.  The visual guide, which was researched and designed by Karim Elgendy with additional contributions from a small research team, was based on raw data obtained from the International Energy Agency and the World Bank. Copyrights for all infographics are reserved for Carboun. No reproduction or republishing of any infographic or part thereof is permitted without prior written consent from the author.

Passive Cooling: Responding to Electricity Demand in the UAE

Wissam Yassine and Karim Elgendy

During the 1990s and the early 2000s, the UAE, and the city of Dubai in particular, witnessed a rapid rate of growth in its built environment driven by a real estate bubble. In the span of a few years the city’s unprecedented rate of growth, which was driven by both demand and speculation, completely transformed the city. But such growth came at a price.  Driven by their need for quick returns, developers cared little beyond delivering a building on time and on schedule. Speed of construction often came at the expense of quality, and issues of performance and energy use played almost no role in the design and construction processes. Common disregard of performance was also fueled by the fact that most buildings were commissioned for developers – rather than owner/occupier clients – since their focus lied solely on reducing initial capital expenditures without considering operating costs that are typically borne by tenants.

These commercial forces, coupled with relatively cheap electricity across the UAE, and a lack of demanding building regulations have paved the way to the development of unsustainable design practices over the last decade. A typical office building in the UAE today is a predominantly glazed high rise tower. Basic design decisions such as orientation, massing, and envelope design are usually made without much regard to their impacts on the buildings’ energy performance, and passive cooling strategies are rarely considered.

Sustainable Development and the Built Environment in the Middle East: Challenges and Opportunities

Karim Elgendy

In the western context, notions of sustainable development often refer to the need to adjust existing economic models in order to maintain better balances between economic growth and social needs, while protecting local ecologies and reducing the negative impact of growth on the global environment.

In the developing world, however, sustainable development takes on a rather different meaning. With the agendas of developing nations focused on addressing basic developmental challenges such as economic growth, water scarcity, food security, and health, other environmental and social aspects are considered secondary at best and for the most part a luxury that a developing nation cannot afford.

The Environment and the Middle East – Pathways to Sustainability – Volume 1.

In the absence of functioning economic models in the developing world, sustainable development here is not about adjustments to maintain balances. Instead, it is about using this economical tabula rasa to build the foundations of a new economic model in which sustainability and the environment are integral. One of these economical foundations is the built environment.

The built environment of our cities plays a major role in shaping the way we live and work, and given its relatively long lifespan its impact is long lasting. Our buildings determine how much energy we use to maintain thermal comfort while our infrastructures determine how much energy we need for transportation. It is estimated that 40% of carbon emissions worldwide is produced from the occupation of buildings with at least a portion of transportation’s 20% share being a consequence of the way our cities are planned.

Our built environment also influences our impact on the local environment as well as our collective health and wellbeing. Thus, as the cities of the developing world continue to grow, they continue to make decisions about the direction their development takes.

In the Middle East, the role of the built environment is becoming more pronounced as the region continues to experience rapid population increases and urbanization. Increased urban densities together with the rise of consumerism, have not only led to an increase in environmental degradation locally, but they have also meant that the region’s traditionally low energy use — and consequently carbon emissions– are set to rise and to play a larger role in global climate change.

But embracing sustainable development in the Middle East faces many challenges which prevent it from becoming part of the region’s development framework and its building industry practices.
