The spatial organization of Kampung Naga is influenced by its location on the valley. The topographical characteristics of the site defines the vertical zonation of the hamlet, which is closely related to the utilization of the landscape into the water management system.

Based on its spatial relation to the settlement area, Kampung Naga can be divided into 3 distinctive zones. The “forbidden forest”, the Sacred Area, is preserved at the top of the composition to infiltrate, filter and store the water through its roots. The settlement area, the Inner Area, is located in the middle with terraced soils following its natural topography. At the lowest level, the Outer Area, fish pond system become the location where almost all the water-related activities take place. Bamboo fences are used as the boundary of the settlement area which at the same time clearly separates these three zones.

Strategic position of the areas on the topography.

Kampung Naga maintains the traditional living with nature amidst modernity that develops around the area. No new technology such as the use of electricity and related devices is allowed in the hamlet. The boundary of Kampung Naga is strictly preserved to balance the number of people whose lives can be supported by the food supply and the ability to manage the wastewater inside the village. While maintaining the number of people who live inside, the rest of the family members can live outside the village.

Although almost all water-related activities are located on the Outer Area, water is treated as a major part of their lives. People keep its space to “breathe”, use it wisely, and purify the wastewater before finally being returned to its original place. Centralization of the activities are designed as an integrated system of water and ecological cycle.

Clockwise. Women use the only water found inside the Inner Area at the Mosque to clean food materials; rice husking station is located above the fishpond; rice terraces which are irrigated from the river; man feeding the fishes; woman washing dishes at the latrine building above the fishponds; woman filling container with Nyusu Water.

Circular Stories

Nature works in circular systems. Living with nature, people in Kampung Naga believe that they need to understand thoroughly and preserve this circularity. Water, as one of the main resources of lives, is used wisely to maintain its circularity. The three water sources which are located on the higher parts of the topography are kept clean free from any activities that could contaminate the water quality. People are forbidden to cut trees in the forest on the hill to maintain its ability to absorb and purify the rainwater to the ground water table. In this case, myth and tradition are used by the community as rules that have to be obeyed. After the water is used for daily activities, it is purified by fishpond systems before finally being returned to the river.

The growth of Kaohsiung is closely related to its irrigation system. The Ksôkong Tsùn irrigation system is a traditional water management and irrigation system used for the purpose of agriculture. The system dates back in 19th century and it has been claimed as municipal heritage site of the city of Kaohsiung.

Circular Stories

In Taiwan, the connection between land and people was once profound and unbreakable, especially in agricultural society before modernization.

Water from river Ko-pin-khe is obtained from a dam, regulated using inlets, to irrigate rice fields following natural topography and weaved an aquatic landscape. Besides the rice fields, water plants production such as taros and water chestnuts, were located in the water retention. This agriculture production, together with aquaculture, formed a circular system that supported one another. On the landscape, Ksô-kong irrigation system accommodated a variety of human activities. At the time people were close to water, scenes like women doing laundry and socializing by the water, children playing in the field, and men fishing on the edge of waterways were common on daily basis.

The map illustrates the landscape condition of the area which is located inside the Lixiahe plain. The geographical condition is a low-lying area surrounded by higher land as the borders. Lixiahe plain is highly influenced by the rivers and the Yellow Sea since it is a deltaic area with an average height of 2.5 meters above sea level. The development of the Yellow river brought various types of soil and sedimentation to the area, and this led to the changed of the ecological condition of the wetland.

Landscape condition is not the only factor that triggered the Chinese ancestor to invent the raised field, but the sociological condition was also a significant aspect. Xinghua is located in the area surrounded by major rivers which were distinctively an important commercial trade area (Yanying etl., 2014). The population overgrew which led to massive food demand. This essential problem can only be solved by increasing the cultivable area (The People’s Government of Xinghua City ,2014).

As a consequence, Xinghua people began to explore the possibility to increase cultivable land. One of the potentials brought by the occurrence of the hygrophytes which began to grow in the area (The People’s Government of Xinghua City, 2014), this is the indicator of the fertile soil quality brought by the yellow river. Xinghua people began to dig the soil from the river and mounding the earth platform to create the floating farmland. It is when the raised field has begun to form.

Catchment map shows different type of soil and sedimentation brought by the Yellow River.

More than thousands of raised fields had been constructed to produce agricultural products for the community. It created a unique landscape pattern for the area. Xinghua became the important cultivated land and the Duotian-raised field also contributed to a flood control system of the area.

Although this technique has been applied in various areas all over the world, Xinghua Duotian is one of the few traditional systems which is still functional. Its long history and adaptability to the excessive water condition make Xinghua Duotian different from other raised field systems. It is recognized as an example of sustainability in agriculture (The People’s Government of Xinghua City, 2014).

The previous flood-prone area has been sustainably utilized by combining forestry, agriculture and aquaculture. The trees planted on the ridges provided fruits and food for the ducks, feeding fishes in the ditches, raising crabs and lobsters inside the soil of the raised field. The natural aqua-planting became a great source of food for birds and ducks while their roots acted as a high quality fertilizer (The People’s Government of Xinghua City, 2014). The new ecological network has contributed to the growth of the crops and created a remarkable landscape to attract a discrete number of tourists. The area is fully established, bringing considerable economic benefits while securing biodiversity and ecosystem services.

Kuttanad Kayalnilam Agrosystem

A traditional paddy farming system
below sea level.
Naeema Ali
2020

The birth of the cultural landscape was marked by the onset of the land reclamation process, locally known as “Kayalkuthu”. When the region encountered acute food shortage in the late 1800s, the virgin landscapes were considered as a gift from the backwaters and were brought to agricultural glory.

Here, water management was quintessentially a unit of the cultural expression of the site specific challenges faced by people, be in terms of topography, climate or social hierarchy. The low-lying landscape was subjugated for the benefit of men and women and how they did this narrates the legend behind the existing agricultural landscape of Kuttanad. These radical ingenuities tell us stories of how humans and nature exchanged roles between being makers and takers of the landscape.

The salt which came across as a curse sealing the fate of the farmers, however, was a blessing for the fishermen due to fish migration from the sea. Hence, the circle of life in Kuttanad was explicitly linked to this cycle of blessing and curse intermingling with the cycle of water and salt. Likewise, Kayalnilams also operated to optimize their performance within this spatio-temporal context specific to Kuttanad.

Delhi Sultanate Waterworks

Ancient network of water harvesting
structures in Delhi, India.

Delhi is located in the Northern part of India being continuously inhabited since the 6th century B.C. Through most of its history, Delhi has served as the capital of various kingdoms, most notably the Delhi Sultanate and Mughal empire. Two prominent features of the geography of Delhi are the Yamuna floodplains and the Delhi ridge.

Clockwise. Satpulla embankment or bund; historical photo of Baoli at Tughlaqabad; historical photo of Hauz-i-khas lake (water tank); historical photo of Sluice gate at Tughlaqabad.

Delhi’s urban waterworks developed in early thirteenth century. They took the following main forms of h auz (water tank), baoli (stepwell) and bund (embankment). Collectively these small structures served the sultanate capitals of South Western Delhi. As with other ancient and medieval water systems, they were incremental and coordinated. Urban lakes, tanks and reservoirs were sited in gently sloping areas adjacent to hillside water control structures.

Delhi sultanate waterworks developed during the early 13th century. They took three main forms – the bund network (embankment), hauz (water tank), and baoli (stepwell). These reflect the main strategies of the Delhi Sultanate water works – the bund network helps in directing and capturing the runoff from the ridge, the hauz stores the surplus monsoon surface water runoff and recharges groundwater while the baolis tap into the shallow groundwater along with storing rainwater.

Circularity of the Delhi Sultanate Waterworks system.

Delhi Sultanate waterworks or harvesting structures were well coordinated with one another, each structure supporting the existence of the other. The bunds, the royal tanks called hauz and the baoli storage structures aided water evaporation and condensation into the atmosphere which again would be captured in the ridge landscape during monsoon.

Today, these water structures lie in a dilapidated state with some having been restored for heritage and tourism purposes. Thus, it is important to learn from past methods of harvesting water to overcome the hydrological problems Delhi is facing today.

The Roman Aqueducts

*Aqua Claudia*, Parco degli Acquedotti, Rome.

A system of pipes, canals, and supporting structures used to convey water from its source to its main distribution point.
Camilla Di Nicola
2020

The Roman Aqueduct systems were built over a period of about 500 years, from 312 B.C. to A.D. 226. Both public and private funds paid for construction. The city of Rome had around 11 aqueduct systems supplying freshwater from sources as far as 92 km away.

The aqueducts were made from a series of pipes, tunnels, canals, and bridges. Gravity and the natural slope of the land allowed aqueducts to channel water from a freshwater source, such as a lake or underground springs, to a city. As water flowed into the cities, it was used for drinking, irrigation, and to supply hundreds of public fountains and baths. The principle was relatively simple: pure and abundant sources in the hills around Rome could be tapped, and their waters diverted into artificial channels running gently towards the city on a gradient designed to deliver them at a useful height, to flow around the city and feed street fountains, baths, and (for a fee) private houses.

Map of the aqueducts in the Municipality of Rome, from the countryside to the city center.

The aqueduct system consisted of several elements, of which the remains can still be seen. The piscina limaria, where sedimentation tanks were used to purify the water, the cisterna, cistern, which collected rainwater or excess water from the aqueducts for periods of drought. At the end of the aqueducts, there was the castellum aquae which distributed the water inside the city. The aqueducts were fundamental to provide drinking water to the city but also for other functions such as thermae, baths, that helped the well-being and health of citizens.

Clockwise. Aqueducts and *cisterna*, cistern in order to collect rainwater; *castellum aquae*, water distributor; aqueducts and *cisterna*, cistern in order to collect rainwater.

Circular Stories

The first thing to do to start the construction of an aqueduct was to find a source of water that was drinkable and at a certain height that could allow its exploitation through pressure. After the inspection of the water quality, long underground tunnels were built in which the water flowed. Furthermore, the purification of the water was also guaranteed by the porosity of the soil (mainly tuff) that filtered the rainwater.

Finally, the settling tank (piscina limaria) improved the water purification by collecting the debris at the bottom of the tank. The canal, or specus, was constructed to maintain a constant slope so as to overcome the differences in height the arches. Excess water from the aqueducts and rainwater was collected in the cisterns.

Once arrived in the city, the water was distributed through the castellum in three different directions: for public fountains, for baths, and for some privileged private houses. The water was also used to clean the streets, improving the sanitary quality of the city. Only then, the water was channelled into the sewer system and then ended up in the river which was organized with a system of grain mills.

The fishing valleys aquaculture system is located in the Venetian Lagoon, Veneto region, Italy. Their first traces have been found since the first 11th century A.D.

Nowadays this extensive fish cultivation system is spread over 8500 ha. of the current lagoon, and its main elements are the fishing ponds, the embankments separating the valleys from the lagoon, the mansions, and the waterworks able to calibrate the amount of fresh water and salt water to introduce in the valleys.

Veneto region, its watershed and the fishing valleys located in the Venetian Lagoon (orange).

The fishing valley master, capovalle, the fishing valley workers and the guardian are the three fundamental figures for the fishing valley management in the Venetian Lagoon. The capovalle is the chief of the fishing valleys, regulating the water regime and employing of seasonal workers; the workers are in charge of different managing activities; the guardian monitors the valley daily.

Circularity between aquaculture, agriculture and agro-tourism in the fishing valleys nowadays. A synthetic scheme.

Since the first decades of the 20th century, the fishing valleys can be addressed as an extensive polyculture, where the main activity of fish farming has been juxtaposed by farm animals breeding (as horses, sheep, hens, goats, cows, etc.), vegetable gardens and orchards (cultivating horseradish, radicchio, asparagus, artichoke, etc.), reeds, mulch, fertilizer
and hay production.

Despite its relatively low rates in terms of production, compared to other intensive aquacultures, this activity is associated with reasonably low management costs: fishing valleys in the Venetian Lagoon are mainly family farms employing seasonal workers during the busiest seasons
(spring and autumn). Recently, many of the fishing valleys have implemented their accommodation activity, providing a slower and lighter touristic alternative to discover the outer lagoon territory, in counter-trend to the mass tourism suffocating the historical centre of Venice.

The Water Mills of Sierra de Cadiz

Water as a driving force in the historical
production of staple food: bread.

The Sierra de Cádiz is located in the north-eastern end of the province of Cádiz; within Andalusia, in Spain. It comprises a large part of the Sierra de Grazalema Natural Park, declared a Biosphere Reserve in January 1977 and a Natural Park in December 1984.

It presents a rugged orography of steep slopes, which causes the Sierra de Cádiz to be the area where the provincial hydrographic network springs. The Majaceite, Guadalete, Guadalporcún and the Zahara and Hurones reservoirs stand out.

In addition to these physical issues, it is a cultural region, since it has been an isolated area (Hispanic-Muslim border during more than two centuries) that has generated among its inhabitants the awareness of sharing a common history and a cultural past.

They are, in addition, functional architectural interventions: for its industrial use and for the required productive profitability, water was necessary for its operation. Therefore, these mills were built with the precision and logic of the small hydraulic engineering works that, together with other minor and usual works in these places, such as ditches, canals, ponds, etc., make up a network of constructions aimed at control and management of hydrological resources that the artisan industries of the Sierra de Cádiz region require.

Clockwise. Water mill “Segundo”, riverside of Arroyo Seco, Benaocaz; Water mill “Primero”, riverside of Arroyo Seco, Benaocaz; Water mill “Alto”, riverside of Arroyomolinos, Zahara de la Sierra; Water mill “El Caballo”, riverside of Gaidovar, ZGrazalema.

The function of the mills determines its design. On a small scale, the mill is distinguished by its location close to the rivers and by the external infrastructure works that channel the water to its interior: the millrace, the well and the wheelhouse.

All the water mills of the Sierra de Cádiz have a horizontal wheel and a well, one or two at most, and they may or may not have a pond. They were built when the watercourses had no speed or sufficient flow.

Almost all the mills had a mixed structure with masonry load-bearing walls of irregular stone, taken with mortar of sand and lime, 60-80 cm thick, plastered with lime and wooden beams. Most of the roofs had one or two water structures, also made with wooden structure, thatched and Arab tile. The main space that articulates the building is the grinding room, located above the wheelhouse.

If it exists, the pond is built where the slope of the land is not excessive to achieve, with minimal construction resources, store as much water as possible. The water is conducted from the pond to the well by the millrace, which bypasses the topography. The well is located in the area of the greatest slope so that the waterfall generates enough force to move the horizontal wheel. The position and length of the millrace result from the position of the pond and the well according to the topography. The system is further optimized with the mill’s proximity to the river for the immediate return of the water to the natural course.

Chinampas agriculture and settlement patterns

Floating gardens of the Aztec Empire of the city of Tenochtitlán.
Catalina Rey Hernández
2019

The Valley of Mexico is a highlands plateau, located in the Trans-Mexican Volcanic Belt. It contains most of the Mexico City Metropolitan Area. Hydrologically, it is an enclosed valley containing the bed of five lakes which are currently extinct. The lakes did not have a natural outlet for water to flow, leading to several floods in the area. The Spaniards decided to drain the former lake-beds to make the city safer, thus transforming the lacustrine landscape into a valley.

Actual system of canals, retention basins and Chinampas in the Metropolitan area of Mexico City.

Chinampas, also known as floating gardens, are an ancient Mesoamerican water system for agriculture and territorial expansion. This was done through a raft covered with soil which was used to cultivate vegetables and flowers as well as to expand the territory on the water surface of lakes and lagoons of the valley of the city of Tenochtitlan, Mexico, converting it into a floating city.

Clockwise. Chinampas agricultural system; aerial view of current situation of land reclamation through Chinampas system; palisade, detail of the construction of the fenced boundary of a Chinampa; cultivation nurseries and channel system; actual use and “reinvention” of the Chinampas water system.

The origin of chinampas started with one of the main problems that the Aztecs faced: lack of land to build their houses. Tenochtitlan island didn’t have enough room for all the inhabitants. Therefore, they fixed this situation by extending those parts of the island where the water was shallow by reclaiming land with alternate beds of reeds and mud taken from the bottom of the lagoon. While the inhabited islands could be enlarged, other lands could be created to support wildlife for hunting and gathering, while other Chinampas served as extensive gardens.

Circular Stories

Today, Chinampas are still present in the southern part of the Valley of Mexico, on the canals of Xochimilco. Although many of these floating gardens were constructed and thoroughly tended to from the Post-Classic period through the Spanish conquest, many of these plots of land still exist and are in active use thanks to present-day farmers that have revived this traditional water system. In addition, the traditional way of cultivation and the form of transport have attracted many tourists who want to experience the Chinampas, through piragüas (traditional canoes) especially to see flower nurseries.

Smoking trees

Manna Gum and Red Gum trees were used to smoke eels and fish. Existing hollows at the base of a tree were expanded and burnt out forming a chimney. Eels and fishes were hung inside the chimney and smoke from the small fire lit inside the base of the tree would start the smoking process. Smoking eels and fishes preserved the meat to be stored for when food was scarce, or to be traded to other areas.
