古河回歸

Te River Returns

摩洛哥帝國城市非斯的阿拉伯聚居區是一處聯合國教科文組織（UNESCO）世界遺產地。然而每況愈下的環境威脅著這一令世人注目的殊榮?；謴途劬訁^這條古老的脈搏，將使污染嚴重、不見天日的非斯河讓這一歷史悠久的衰退之心重煥生機。

水即是生命——就是如此簡單。當這種珍貴的資源陷入短缺時，人們就會對它的價值產生尤為深刻的認識，而這正是馬格里布沙漠的情況?！八俏覀兾幕闹行囊??！蹦β甯缃ㄖ煱R扎·沙烏尼解釋道。的確，由于水象征的純凈在宗教生活中發揮了舉足輕重的作用，以至于水井或噴泉成了非斯大部分住宅的特征。對于許多以這個摩洛哥北部城市為家的人來說，再沒有什么比潺潺流水更悅耳的聲音了。

建在水上

非斯城選址在一條大河肥沃的谷地中絕非偶然?！癕edinat Fas”是伊德里斯一世于789年在右岸創建的。20年后阿利亞在左岸建成。中世紀期間，這兩座城市合為一座生機勃勃的大都市，并一直快速發展。

朝代幾經更迭——伊德里斯王朝、馬林王朝、阿拉維王朝——非斯一直是王朝的都城，與拉巴特、馬拉喀什和梅克內斯并稱帝國四大城市。直至1912年法國人到來，首都才遷至拉巴特，1956年獨立之后一直延續至今。

雖然是出于實際考慮而進行的整治，但給非斯帶來的效果意義重大——這座城市曾一度喪失它的經濟和政治地位。大量受過教育的人流向其他中心，作為世界上最古老的大學——自859年成立以來一直延續至今的卡魯因大學所在地，它在知識界的聲望也受到了影響。

作為聚居區曾經的生命之血，今天的非斯被稱為“垃圾之河”。在穿過聚居區時，這條河大部分都被藏在地下。

聚居區——活的機體

非斯河僅有4m寬。但它是這座100萬人的城市走向衰落最有力的象征。這過去賜予生命的河流如今不過是條排水道，被戲稱為“垃圾之河”。在非斯的歷史中心，即聚居區，情況尤為嚴重。聚居區約有300hm2，有伊斯蘭學校、老客棧、住宅、宮殿、花園和噴泉。大部分都藏于素面高墻之后，這些自在天地中是典型的阿拉伯-安達盧西亞建筑。1981年，該地區被UNESCO列為世界遺產地，它的各種精神和文化價值得到認可。但這不是一座博物館。

在阿齊扎·沙烏尼看來，這個聚居區是一個活的機體。這些緊密交錯的街道煥發著勃勃生機。手工藝行業保持著繁榮的貿易，尤其是河邊一線的舒瓦拉制革廠。原來給皮革清洗、加工、磨光和染色的大缸仍在使用，并成為大受歡迎的旅游點。然而，傳統的皮革加工方式早已失傳?，F在用的化學藥劑——鉻等重金屬不可避免地流入河水。但即便在達到聚居區之前河水就已被嚴重污染了。這座城市中心給河水增加的廢水量就是寓言中壓在這頭長期受苦的駱駝背上的稻草。

這不僅是流淌在聚居區中的有毒雞尾酒，還有令人作嘔的惡臭。居民們對多年的不作為忍無可忍，終于決定自己動手，在5年前用混凝土把河填上。如今只能偶爾遇到看不見底的水和被污染的河岸?！胺撬购邮且粭l老鼠橫行的臭水溝，”阿齊扎·沙烏尼說道，“它的狀況根本不配作摩洛哥歷史的寶珠！”

世界遺產狀態遭受威脅

非斯河的衰敗象征著聚居區整體的衰退。在看似陷入惡性循環的處境中，大量建筑亟待修繕，而新建筑往往也質量很差。公共空間稀缺——20萬居民只有兩個小公園。UNESCO看到了這一情況并公開了意見，認為非斯正面臨著失去世界遺產地位的威脅。

政府把UNESCO的話放在心上，并作出積極回應。在規劃中，兩座水處理廠將用于城市排污，河道將重見天日，并復原在聚居區中的歷史河道。非斯古老中心的生氣將會再次流動起來。為實現這一綜合復興規劃，圍繞阿齊扎·沙烏尼建立了一個團隊。這位曾在美國留學的建筑師回到了她出生的城市——“我希望承擔這個項目是因為我愛我的家鄉。”

非斯是摩洛哥帝國四大城市中最古老的。它的聚居區是UNESCO世界遺產地。

以人為本

河道的復興規劃以及城市更新的相關策略是同城市規劃師兼景觀建筑師田島高子（音譯）以及多位專家學者合作制定的。

改善聚居區中人的生活質量是關鍵。這一策略的目標是綜合解決城市的經濟和社會生活問題以及河道的生態。規劃采用了各種措施，以改善水體質量，創造更好的野生動物棲息地。人造濕地的引入將調節過量洪水、凈化暴雨雨水、促進地下蓄水，并創造更多棲息地。而這一切設想都在合理的預算中。

“今天這條河的水流經國內最肥沃的地區，到了這里卻成了從拉巴特流入大西洋的臭泥漿。復興非斯河不僅有利于我們的城市和聚居區，更將惠及摩洛哥全國。”阿齊扎·沙烏尼解釋道。

要城市客廳，不要停車場！

城市尺度的總體規劃集中在改善區域水質的問題上，此外設計了3個關鍵性的地段尺度的干預措施。它們的目標是同時提高水質、恢復污染的場地、在最貧窮的地區創造公共空間，并使經濟發展復蘇?？傊?，目的在于讓這條河與聚居區重新融為一體——成為城市基礎設施的中心生命線。

為了實現這個目標，第一個項目就從老城中心的停車場開始?！盀榱酥噩F河流，必須消滅它?！?阿齊扎·沙烏尼說道。這個停車場將改造成一個巨大的城市客廳，而用回收皮革制成的頂篷將遮住炎炎烈日?；厥盏哪玖蠈⒅瞥晒珗@的長椅。廣場中心的暴雨塘既實用又美觀——濱水植物將通過給徑流供氧使河水恢復名副其實的生命。

10 非斯聚居區新的公共空間的改善途徑/Procedures for new public spaces in the Medina of Fez

The medina of the Moroccan imperial city of Fez is a UNESCO World Heritage Site. However its continuing decline threatens this prestigious title. Remediating the medina's historic lifeline, the heavily polluted and barely visible river Fez, will return to this ancient ailing heart its dynamic soul.

Water is life – it is as simple as that. But when this precious resource is in short supply, as in the desert lands of the Mahgreb, people are especially conscious of its value. "Water is a central part of our culture," Moroccan architect Aziza Chaouni explains. Indeed, such an important role does the symbolic purity of water play in religious life that a well or fountain is a feature of the majority of houses in Fez. For many people who call this north Moroccan city home, there is nothing more beautiful than the sound of running water.

Built on water

Locating the city of Fez in the fertile basin of a large river was no accident. Te "Medinat Fas" was established by Idris I in the year 789 on the right bank. Twenty years later came "al-Aliya" on the left. During the Middle Ages, the two merged into a single lively metropolis which continued to grow rapidly.

Under successive dynasties – the Idrisids, Merinids and Alawids – Fez was the kingdom's capital, ranking alongside Rabat, Marrakech and Meknes as one of four imperial cities. It was not until the French arrived in 1912 that the capital was moved to Rabat, a move that remained after independence was achieved in 1956.

Although undertaken for practical reasons, the effect on Fez was significant – the city lost much of its economic and political status. With many of its educated also drawn away to other centers, its intellectual renown, as the site of the world's oldest continuing university – al-Qarawiyin, established in 859 – also suffered.

The medina – a living entity

It is only four meters wide, the river Fez. But it is the most potent symbol of the decline of this city that today hosts some one million people. What was once a life-giver is now little more than a sewer. Nick-named the "River of Trash", the situation is especially critical in Fez's ancient heart, the medina. Te medina covers some 300 hectares – it is home to madrasas, fondouks, residences, palaces, gardens and fountains. Most lie hidden behind high plain walls, but these inner worlds represent the quintessential Arabo-Andalusian architecture. In 1981, the area was declared a UNESCO World Heritage Site, acknowledging its spiritual and cultural values. But this is no museum.

According to Aziza Chaouni, the medina is its own living entity. Tese close-knit streets buzz with energy. Handicraft enterprises maintain an active trade, principally the Chouarra leather tanneries which line the river bank. The original vats for washing, treating, smoothing and coloring the skins are still in use, and are a popular tourist attraction. However, traditional means of working the hides are long gone. Now it is the job of chemicals – heavy metals such as chromium inevitably find their way into the river. Yet even before the river reaches the medina it is heavily polluted. Adding the city heart's quantum of wastewater to the flow is the proverbial straw on this long-suffering camel's back.

Not only is it a toxic cocktail that flows through the medina, the stench is just as nauseating. Residents, fed up with years of inaction, finally念，而作坊本身會翻新為皮革設計中心。

這個項目是同經濟專家一起策劃的，目的在于為城市的皮革產業抓住各種新的機遇，并向國際標準看齊。過去關注的只是產業加工，未來在這里建設的設計合作社將提供有附加值的高質量產品。

“這是一個百廢待興的時機——我們與市政府合作，進行調研，走訪居民，明確他們的需求?！?/p>

“聚居區中的人是我們不變的中心。我們所做的必須符合他們的利益?！?/p>

團隊的很多工作都集中在向居民表達總體規劃的愿景?！斑z憾的是，很多人還看不到這個項目的潛力。”有些人認為應該回到過去的樣子，而不是這一策略的目標：創造息息相關的新環境——21世紀的生活聚居區，而不是僅僅作為古跡的博物館。其他人則開始自問：在人們情愿搬到另一個城市生活區、住進現代而非傳統的住宅時，為什么專挑這個聚居區進行復興。

在這種情況下，阿齊扎·沙烏尼自己則憧憬著卡魯因大學從城市周邊的美式校園遷回聚居區的那一天。“那將是件了不起的事。”她開心地說。

走在鋼絲上

這位建筑師堅信該項目證明了這個聚居區能夠通過改造，在綜合城市發展的框架中保留其文化完整性和經濟價值。通過結合21世紀的社會需求與UNESCO保護世界遺產的決心，這個項目具有在各地推廣的巨大潛力。許多阿拉伯國家都有相似的問題。它們的聚居區也面臨著威脅——公共空間稀缺、基礎設施老化、居民外流去追求更現代的生活設施。然而，阿齊扎·沙烏尼很清楚每個城市更新策略的制定都是需要走鋼絲的。她以拋棄老傳統去追求外國投資的馬拉喀什為例。“政府在看到資金流入時就亟不可待地表現出積極的態度，”她解釋道，“可是，從長遠看，代價會很大?！倍鷳B問題僅僅是其中一個方面。

馬拉喀什的教訓在非斯制定總體規劃時得到了借鑒。“我們希望這個聚居區在21世紀仍是一個富有生氣的城市環境，而不是一個博物館藏品。我們會問自己這樣的問題：我們怎樣讓人留在聚居區中？如何勸說他們不要賣房搬走？”古河復興，作為這個項目綜合方法的核心，一直是解決這種問題的關鍵——事實上，它使一顆衰竭的心重煥生機。（尚晉 譯）took matters into their own hands, covering the river over with concrete five years ago. It is only an occasional glimpse now that one has of opaque water and polluted river banks. "Te Fez is a sewer full of rats," Aziza Chaouni says. "Its condition is unworthy of this jewel of Moroccan history!"

World Heritage status under threat

The decline of the river Fez is symbolic of the decay of the medina as a whole. Seemingly imprisoned in a downward spiral, many buildings are in urgent need of restoration, and what is newly built is often of poor quality. Public space is rare –for 200,000 inhabitants, there are only two small parks. UNESCO is aware of the situation and has made its opinion known – the loss of Fez's World Heritage status is under threat.

Te government took UNESCO at its word and responded to the call. Two water treatment plants are planned for the city's sewage, the river will be reopened and its historic course through the medina reconstructed. Once again it will flow – the dynamic soul to Fez's ancient heart. It is around Aziza Chaouni that a team has been established to put this comprehensive rehabilitation plan into action. Having studied in the United States, the architect returned to the city of her birth –"I wanted to work on this project because I love my hometown."

Focus on the people

Te revitalization plan for the river, as well as a linked strategy of urban renewal, was developed in conjunction with town planner and landscape architect Takako Tajima and a variety of specialists and academics.

Improving life quality for people in the medina was the focus. Te strategy aims to comprehensively address the economic and social life of the city together with the ecology of the river. Various measures are planned in order to improve water quality and thereby enhance wildlife habitats. The introduction of constructed wetlands will manage excess floodwater, clean storm water, promote groundwater recharge and encourage habitat creation. Yet all this is envisaged within a modest budget.

"Today the waters of the river run through the most fertile areas of the country only to arrive as a stinking soup entering the Atlantic at Rabat. Resuscitating the river Fez not only profits our city and its medina, but the whole of Morocco," explains Aziza Chaouni.

Living room, not car park!

Whilst the city-scale master plan focuses on improving regional water quality, three critical sitescale interventions have been conceived. Tey aim, concurrently, to enhance water quality, remediate contaminated sites, create public spaces in the poorest areas, and revitalize economic development. Above all, the intention is to reintegrate the river into the medina – as the central lifeline of the city's urban infrastructure.

To achieve this, the first project targets the car park in the heart of the old town. "For the river to reappear, this must disappear," Aziza Chaouni says. Te car park will be turned into a huge living room, shaded from the sun's relentless heat by a canopy of recycled leather. Recycled wood is intended for park benches. A storm water basin at the plaza's center will be both functional and aesthetic –riparian plants will literally resuscitate the river by oxygenating run-off water.

Playground and botanical garden

Te second major project focuses on bringing a playground to the medina. Where the river bank now hosts an informal waste dump, a garden of children's voices will soon be heard. Terraced wetlands will enhance water and air quality. Recycled leather and carpenters' off-cuts are similarly foreseen as shade protection and park benches respectively. Recycled tires complete the picture – they will be used in the creation of the park equipment itself.

Meanwhile, the last of the three projects focuses on revitalizing one of the main perpetrators of river pollution as a public botanic garden. With the city's tanneries moved to a new industrial quarter, the opportunity exists to transform the old tanneries site and its contaminated surrounds. Even the tanning vats will be integrated into the concept, while the workshop buildings themselves will be renovated as a Center for Leather Design.

Developed together with economic specialists, this project aims to capture new opportunities for the city's leather industry, and align with international standards. Where previously the focus was only on industrial processing, in future design cooperatives offering value-added high-quality goods will be developed on site.

"Our aim is local value creation, thus enhancing local employment opportunities." All building projects in the context of the strategy are implemented by artisans using traditional building materials and techniques – clay bricks, fired onsite, as well as white plaster. Energy efficiency and a seamless aesthetic with existing structures is the overall intent.

Pushing boundaries

Aziza Chaouni sees this project as a life's work –"there is so much to do! We must prioritize." To advance the projects and engender more community involvement, she has formed an NGO "Sauvons Oued Fez" (Save the Fez River), a network of graduates, specialists and local business-people.

"It is a busy time – we work with the city authorities, we conduct investigations, interview residents, clarify their needs.

Always the people of the medina are our focus. What we do must be in their interests."

Much of the team's work is concentrated on communicating the master plan's vision to residents. "Unfortunately many cannot yet see the potential in the project." Some are convinced things should return to the way they were, earlier, rather than the strategy's goal which is to create something new yet still relevant – a living medina for the 21st century, not a museum relegated to antiquity. Others ask themselves why the medina should be earmarked for revitalization when people would rather move to another city quarter and live in modern rather than traditional housing.

Meanwhile, Aziza Chaouni herself looks forward to the day when the al-Qarawiyin University could return to the medina from its American-style campus on the outskirts of the city. "Tat would be great," she grins.

Walking a tightrope

The architect is convinced this project demonstrates that the medina can be adapted to retain both its cultural integrity and economic value within a framework of integrated urban development. By meshing 21st century social needs with UNESCO's dedication to preserving world inheritance, the project has significant potential to be replicated elsewhere. Many Arab countries are experiencing similar problems. Teir medinas are also in crisis – too little public space, decaying infrastructure, residents leaving in search of more modern amenities. However, Aziza Chaouni is conscious that the development of each and every urban renewal strategy entails walking a tightrope. She cites Marrakech as an example where old traditions have been lost in the desire for foreign investment. "Authorities cannot help but be positive in the first instance when they see money flowing in," she explains. "However, in the long-run, there is a high price to be paid." Not least of which is ecological.

Te lessons of Marrakech have been studied by Fez in the development of its master plan. "We want the medina to still be a living urban environment in the 21st century, not a museum artifact. We ask ourselves questions like: How can we keep people in the medina? Encourage them not to sell up and move out?" Revitalizing the river, the core of the project's comprehensive approach, has been key to answering such questions – in truth, it returns to an ailing heart its dynamic soul.
