Petra's Ancient Pollution Problems: A Historical Perspective

The ancient city of Petra, with its impressive architecture and bustling trade, has undoubtedly faced problems with pollution and natural disasters. With a history spanning over 2000 years, Petra was once a thriving centre of trade and cultural exchange. However, today, it faces various environmental challenges, including flash floods, erosion, and the impacts of unsustainable tourism. The site is particularly vulnerable to flooding due to its location in a basin surrounded by mountains. To address these issues, efforts are being made to repair and revive ancient water management systems, showcasing the resilience and ingenuity of those working to protect Petra's rich heritage.

Seasonal flooding and drought

The ancient Nabataean civilization that once inhabited Petra was no stranger to seasonal flooding and drought. The same features that made the area around Wadi Musa attractive to the Nabataeans—its winding canyons, high peaks, and protected valleys—also made it susceptible to flooding. Archaeologists have discovered that the Nabataeans engineered an interlocking system of terraces and small dams to safeguard ancient Petra from flooding.

The Nabataeans were adept at surviving in the desert due to their expertise in water collection and distribution. They constructed an intricate network of rock-cut channels and underground pipes to transport water from permanent springs and seasonal streams. Additionally, they developed a method for collecting and storing water in watertight holes or cisterns, hidden underground to prevent evaporation and protect their water supply from enemies.

However, the challenges of managing water in the region have persisted into modern times. In December 2022, Petra experienced heavy flooding. To address this ongoing issue, local community members have collaborated with experts to repair and restore the ancient Nabataean terraces and dams. This annual maintenance is necessary to clear the mud and rocks that accumulate during the winter rainy season, providing employment opportunities while also helping to safeguard the site.

Climate change has also contributed to longer dry spells, making it more difficult to maintain the fields that once thrived in the region. The combination of flooding and drought presents a complex challenge for those working to protect the archaeological site and the tourism industry that depends on it. By combining ancient solutions with modern innovations, there is hope that Petra can adapt to the extreme conditions brought about by climate change.

Unsustainable tourism

Petra has long been a popular tourist destination, with most modern visitors approaching the site from the east through the narrow, winding gorge of the Siq. However, unsustainable tourism practices have led to a host of problems for the ancient city. The site has seen a substantial increase in tourism, especially since it received widespread media coverage in 2007 during the New 7 Wonders of the World Internet and cellphone campaign. In 2019, Petra received 1.2 million total visitors. This influx of tourists has put a strain on the site's infrastructure and natural resources.

The Jordanian government's decision to relocate the Bedul Bedouin community, the original inhabitants of Petra, to the nearby settlement of Umm Sayhoun in the 1980s is an example of how tourism has been prioritized over the local community. This move was part of broader initiatives to settle Bedouin communities and promote tourism in Petra. While the Bedul Bedouin people now engage in local tourism, this displacement has disrupted their traditional way of life.

The increase in tourism has also led to concerns about the preservation of the ancient structures and archaeological remains in Petra. The majority of these structures are tombs, and they are vulnerable to damage from flash floods, which have become more frequent due to climate change. To protect the site, guardians of Petra are turning to ancient solutions, such as the Nabataean water management system, which includes an interlocking system of terraces and small dams to flood-proof the area.

Additionally, the high volume of tourists can contribute to environmental issues such as pollution, waste accumulation, and erosion. The impact of unsustainable tourism practices on Petra highlights the need for responsible and regulated tourism that prioritizes the preservation of the site and the well-being of the local community. Conservation efforts are being made by organizations such as the Petra National Trust (PNT), which was established in 1989 and has worked on projects promoting the protection, conservation, and preservation of the Petra site.

Erosion from flooding

Petra, the ancient city in Jordan, has been facing problems with flash floods, which have been exacerbated by climate change, urbanisation, and loss of ancient flood-management infrastructure. The site is vulnerable to seasonal flash floods due to its elevation and the surrounding topography, which includes winding canyons, high peaks, and plateaus. The recurrence of flash floods has had astounding impacts on Petra and its monuments, leading to erosion and threatening the lives and property of those in the area.

The ancient Nabataeans, who inhabited the region until around 300 AD, also faced problems with seasonal flooding. They developed an interlocking system of terraces and small dams to manage water and protect the city from floods. However, over time, the terraces and dams have been damaged, and the ancient flood-management infrastructure has been lost. As a result, the site has become more vulnerable to flooding.

In recent years, there have been efforts to repair and revive the ancient flood management system. Taher Falahat, a cultural heritage expert, has been working with the local community to clean and repair the ancient dams and terraces. These structures are essential for managing water and protecting the site from flash floods. The work also provides employment opportunities for the local community while helping to safeguard the site.

The impacts of flash floods on Petra have been devastating. The floodwaters rush down the streets, leaving behind boulders, gravel, and pebbles. The lower city centre along Wadi Musa is particularly vulnerable and has been covered in accumulations of boulders, gravel, sand, silt, and clay in the past. The flooding also endangers the archaeological site, threatening the tourism business that the locals rely on. The erosion caused by flooding has damaged the inscriptions and reliefs created by the ancient Nabataeans.

Overall, the erosion from flooding has had significant impacts on Petra and its surrounding areas. The loss of ancient flood-management infrastructure has increased the vulnerability of the site to flash floods, leading to devastating consequences for the local community and the archaeological site. The efforts to repair and revive the ancient flood management system are crucial for protecting Petra and its monuments from future flooding.
