Abstract Solana’s Alternative Growth
Human has become a geological force. Someone can argue that this has become recognisable fact afforded by the new geological epoch that we are living in and comes with the name of the Anthropocene after the Nobel prize winning atmospheric chemist Paul Crutzen. Anthropogenic activities driven by a hubris of human exceptionalism supported by a false Promethianism and framed by sterile geopolitics imposed metabolic rifts on the planet and left traces reminders of a necessity to address a possible future without us.
In the post- Anthropocene era, our intension is to design the strategy for dealing with these problematic remains from the period of the Anthropocene, and utilizing the alternative and speculative scenarios to metabolise the local cycle in an efficient way. The abandoned Solana Ulcinj is one of the cases where a bankruptcy of a salt factory endangers a biodiversity due to the abandonment of a metabolic circle that was pumping energy and life to the broader area of Ulcinj. The artificial salty landscape rich in nutrition become a habitat for an immense number of species of birds during they migratory flights. The 1990’s bankruptcy has disrupted a settled metabolic circle formed by salt, migratory flight tracks, birdwatching and financial input to the Ulcinj area. How therefore we designate the problem at the urban scale afresh? How speculative scenarios, that do not restore – impossible and futile – what was existing there suggest alternative metabolic circuits that will redefine a different urban scenario and a new form of habitation for human and non-human entities. In this sense the project suggests possible strategy for the post-Anthropocene.
In order to approach the project methods, involve methods of capturing and mapping that exceeds normal urban design methods but in spatial and temporal scales. In this sense the urban problem is opened up in spatiotemporal scales that far exceed that of human. The decision to start from salt reveals an intention to allow the site to construct its own history and its peculiar expression. By sensing and recording through various points of view that range from microscale photography of salt crystal growths to Satellite mapping in order to identify salt concentrations on the site we aimed to set up a field through which a material system is computed and grow to occupy the planetary surface of that thick section of investigation. The resulted urban form is an alternative scenario that human and non-human entities interact in a metabolic sphere. Firstly, based on the visited of our site and the maps from European Satellite Agency, we found that plenty of waste material of salt remained on the site. Therefore, it is significant to speculate the alternative potential for local urban sphere and biosphere. Then, we conducted systematic branching system to do the physical experiments of crystallization in order to observe and extract the morphogenesis emergence of salt material. Specifically, we focused on the morphogenesis of crystallization via observation of physical experiments so that we concluded the relationship between the essential parameters of morphogenesis and manual substratum. Secondly, in order to have higher accuracy and comparable experiments with the manual branching system, we utilizing the algorithm of the L-system to generate the specific substratum for physical experiment. Moreover, the L-system is based on the mathematic computation so that we fully manipulated each parameter such as length, angle, scale, generation and codes to build up the material system. Thirdly, it is significant to organise the material system by the L-system which including some prototypes, components and compositions of substratum, each scale of substratum presenting different scale of morphological behaviour of crystallization. Fourthly, comparing with the physical crystallization, it is important to simulate it via the customized algorithm of diffusion limitation aggregation system as an agent. Reasoning that not only we could observe the dynamic morphogenesis at different stages but also could harness this system to speculate its behaviour and the distribution of salt’s crystals on the substratum. Fifthly, our strategy is that growing substratum by the L-system according to the dynamic salinity and water flow in different seasons. On the other hand, the capacity of substratum consists of some functions such as catalytic cells, bird nesting, human activities and so on base on the dynamic cycle and redundancy of information extracted from our site. For instance, the catalytic cell which consists of saline water as a media and mental could generate electricity for activating the pumping system. Therefore, the cycle of biosphere and urban sphere can be balanced as previously.

In This chapter,a satellite remote sensing is being used to document the local information and to map the history of salt production in Ulcinj. Firstly, we do the research about the transition of the use of saline and the settlements condition near Ulcinj will be researched and that eventually will lead us to justify salt as our initial input material. By looking into the physical conditions of Ulcinj, we collect data from satellite maps based on Level1 data from the ESA(European Space Agency). Level-1 focused data are transformed from level-1 data by the application of algorithms and calibration data to form a baseline engineering product from which higher levels are derived. The Level-0 products consist of compressed and unfocused Synthetic Aperture Radar raw data. Level-0 products are the basis from which all other high level products are produced. It includes noise, internal calibration and echo source packets as well as orbit and attitude information. Water, wind, and saline dune are the basic elements that we focus on. Through the scale of the view from the satellite, we analyse each of the above elements and study its affective relationship in the site. Based on the information of that initial study, we will discuss the physical conditions of Ulcinj that might influence the urban infrastructure, and also the varying position of Solana as consequence of the transition of local salt industry to ecological tourism.

//Ulcinj Salt industry & settlements near the dealt beach Solana is one of the largest salines of the Mediterranean region. It is a completely man-made, artificial landscape which founded in the nineteen twenties. it is region that was selected as an industrial salt production area by former Yugoslavia because it can become hot with the constant wind at the height of 10 meters above the sea. These conditions are perfect for evaporation of water. The salt pans and machinery were constructed from 1926 and 10 years later the first salt was harvested. Additional salt pans were added to improve the crystallization process in the 1960s to 1980s. The falling apart of former Yugoslavia and The political and economic transformations in Montenegro afterward caused the Solana Ulcinj to go bankrupt in 2005. And the value of salt on the world market had drastically decreased during 1990’s. Therefore, the industrial salt production in the Solana was no longer profitable. After that Solana starts to cooperate with EuroNatur aiming to protect the unique ecosystem of the salina and for developing the area for touristic purposes. (“ Project Solana Ulcinj,� 2016) But still it cannot save Solana economically and ecologically.

//Water Resources Distribution NDWI (Normalized Difference Water Index) map we focused on water dynamic which can clearly observe from the NDWI (Normalized Difference Water Index) map. This operational field affords to engage the territory in terms of degrees of wetness and it is based on the possibility to algorithmically compute the difference in reflectivity of ground materials that possess a different water content. The equation is used to monitor changes related to the water content in water bodies, using green (i.e band3) and NIR (i.e band8) wavelengths, defined by McFeeters (1996) which is (B3-B8)/(B3+B8). An NDWI image can be generated accordingly with the resolution 10 meters per pixel.

The wettest zones are rendered in purple while the driest zones are rendered in blue. The darkness of blue indicates the depth of water. Based on the NDWI maps we can clearly identify the water distribution area and also the whitest area during the dry season, potentially saline dune distribution area can be allocated.

//Water Resources Fluctuation
NDWI (Normalized Difference Water Index) map In order to understand the water flow direction and the fluctuation throughout the whole year, we collected nine NDWI maps which were captured in specific dates. A closer look into the specific salina through the NDWI maps proves that the waterside is changing due to the different levels of high salinity as well as the sea water flowing in from October and flows out in April. Which is why the annual cycle of salt production started in late April. The initial seawater with a concentration of 29 grams per litre is pumped into the evaporation basins pond by pond started from an east south part of the whole area. And evaporation is processing from June onwards. Water dynamics help us to relocate the crystallization and to understand the network of canals which connect the saltpans.

//Water Resources Fluctuation Canals under the water Due to the cycle of salt production started in late April. Saline water should be transported to adjacent evaporation basins when the evaporation goes into different stages. From the diagram of Euronatur assessment, the transformation of saline water during the salt production has been shown when the saline water was pumped from neighbour salt pans. And compared to the ESA maps through 2016, the water surface was also changed due to the tides. Based on these two sources, we use shortest walk to simulate the water flow between basins and the canals under the levees.

We divide the Saline into two-dimensional grid and then using an algorithm to map the whitening area. In the diagram, the height of each pillar is proportional to the brightness of each pixel. Two diagrams indicate the difference of saline dune distribution in April and August, as the typical examples of wet and dry season separately.

//Representation of salinity in site After the digital reconstruction of saline dune distribution area, we 3d printed a series of models that also illustrates the data in physical medium. Based on our original maps, we use the height of pillar to represent the topography of the site, and the cross-sectional area to represent the salinity in different evaporation basins. We assume that the different scale of pillars and the distance between them will affect the process of salt crystallization. And our documents of this physical model confirm our thoughts.

Therefore, we can alter the process of the crystallization through controlling variables. Before conducting several physical experiments, we need to summarize few arguments with controlled trials, such as: humidity, density of saline water, temperature, fluctuation of the flow, which are quite common phenomenon in SOLANA ULCINJ. Before conducting the experiments, several types of equipment shall be set to simulate the natural environment, such as fans, the frothing machine and digital camera to record every step of the experiments in order to analysis the dynamic behaviours of the crystallization. The first step of the experiments is to stir salt into boiling hot water until no more salt will dissolve (crystals start to appear at the bottom of the container). Be sure the water is as close to boiling as possible, After that, use the glass tank as the container. Set the substratum into the saline water. The fan, heater and frothing machine can be used to accelerate the process as well.

//Principle of crystallization The molecular formula of table salt, which is sodium chloride, is NaCl. Table salt is an ionic compound, which breaks into its component ions or dissociates in water. These ions are Na+ and Cl-. The sodium and chlorine atoms are present in equal amounts (1:1 ratio), arranged to form a cubic crystal lattice. In the solid lattice, each ion is surrounded by six ions having opposite electrical charge. The arrangement forms a regular octahedron. The chloride ions are much larger than the sodium ions. The chloride ions are arranged in a cubic array with respect to each other, while the small sodium cations fill the gaps between the chloride anions. Salt is very soluble in water, so the growth rate of salt crystals is diffusion controlled. Apart from the in Suence on the mean crystal size, the low driving force for crystallization also strongly reduces. agglomeration. There are three mechanisms for the incorporation of impurities in the Real crystalline product. The Rest is the direct incorporation of the impurity in the crystal lattice, the second is the formation of inclusions and the third is the insufficient washing of the crystals.(Kostick,2010)

Epsom Salt Molecular forms
Concentration: 1.6S: 1.0W
//Principle of crystallization Magnesium sulfate is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt. The monohydrate, MgSO4·H2O is found as the mineral kieserite. The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority was used in agriculture. Anhydrous magnesium sulfate is used as a drying agent. The anhydrous form is hygroscopic (readily absorbs water from the air) and is therefore difficult to weigh accurately; the hydrate is often preferred when preparing solutions (for example, in medical preparations). Epsom salt has been traditionally used as a component of bath salts. Epsom salt can also be used as a beauty product. Athletes use it to soothe sore muscles, while gardeners use it to improve crops. It has a variety of other uses: for example, Epsom salt is also effective in the removal of splinters.(Karl Heinz Büchel, Hans-Heinrich Moretto and Dietmar Werner,2000)

//Phsical Experiment with Epsom salt
In the first experiment, we choose Epsom salt as our agency. Epsom salt has been traditionally used as a component of bath salts. Before conducting our experiment, we simply analyse the forms of the particles, under normal circumstances, the salt particles are mainly square and transparent. The process of the crystallization is simple to control. However, it requires to be painted some seeds along the substratum previously, after sinking it inside the saline water, it will take about a night to crystallize, the final formation is column crystals whose sizes are determined by the concentration and time. Based on the digital camera’s recording, the process of the crystallization normally took place from the parts where seeds have been planted, depending on the size of the seed, the result can be quite different. Before taking the crystallized models out of the tank, the forms of the crystals are mostly transparent and assuming the square shape. After several weeks placing the models in the ventilated room to dry, a white layer of membrane begins to cover the transparent crystals. Although the result of Epsom salt can be exaggerated, the course is easy to be recorded and the changes of the crystals` formation are significant.

Table salt is another agency that requires less saline solution than the Epsom salt. In addition, there is no need to sink the whole structure inside the saline water. Due to the special siphoning effect, the phenomenon of the table salt crystallization is interesting. Firstly, despite the crystallization on the process begins near the water surface, gradually the siphoning affect happens on the surface of the container, mostly the pattern fans out along the surface due to the evaporation. The siphoning effect will demonstrate different pattern due to the different material of the surfaces well. In terms of the crystallization formation, the differences are appearing between the water surface and the substratum: the forms of the crystallization which are under the water are normally smaller and emerging in a square shape, however, as for the assembly morphologies which are above the water surface, the crystals are predominant spheroidal particles, the closer to the surface, the bigger the crystals are. In conclusion, based on the facade structure of the model, each layer will show the different result of crystallization, not only the formation, but also the density and size of the crystals.

//Agent fo salt crystallization Diffusion limited aggregation algorithm Salt crystallization is the main point that our project focused on. Therefore, the agent of salt crystallisation is part of our intelligent material system. In order to simulate the crystallization, the DLA algorithm is one methodology which could achieve the goals. In the first step, identifying the key parameters which could influence the behaviour of crystallization in the DLA. In addition, there are many physical influences factors could affect the crystallization, it is significant to add specific parameters such as the direction of growth, the speed of growth and constraint of the growth. By observing the growth of the crystals with the DLA, we could analyze the morphology of it and compare the growing pattern with the crystallization of physical experiments.

The other key factor could influence the morphogenesis of crystallization is the substratum which could generate by the algorithm of L-system and so on. In addition, we Identified the subsidiary factors such as the strength of field and intensity of trace which could affect the behaviour of salt growth and the geometry of results. Therefore, the evidence shows that the verification of the morphology with “digital crystallization� is comparable and 81 analogous to our observation of physical experiment.

According to the physical experiment, we realized that the growth of crystals not only at the beginning but also growing larger continuously. For instance, in the diagram below demonstrates that the red particles are in the new growing stage and the white ones are the former growing particles. The red particles will transform the size from small to large and from red to white as time goes on.

//Substratum Statement
In the intelligent material system, the agent of the generating substratum is part of the holistic system. In order to build up a systematic material system, we created several prototypes based on the property of physical experiments that we observed. Then, the composition of the substratum is organised by the different prototypes. Therefore, we understood that the correlation within the property of crystallization, different scale of substratum and the specific spatial pattern of the substratum.

One of the major agents in the material system is the agent of sensing data. There are two functions that sensing algorithm can do. Firstly, this agent could identify the distribution of salt crystals on the site and on the terrain, and then transform the data into the 3D model. Secondly, the data of distribution of could also send the feedback to the agent of generating substratum in order to selforganise the further substratum for the crystallization.

//Urban Protocol of Solona Ulcinj
Our intention is to rework with the human force such as designated material system, then turn the trace of Anthropocene into a new urban scenario which can afford to re-metabolise the local biosphere and social sphere for the post-Anthropocene. Referring to the redundancy and complex theory, the more physical influences of crystallisation that we involved in, the higher accurated anticipation of crystallization we can achieve. Regarding the physical influences of the current environment in Ulcinj, there are several key factors can affect the salt crystallization such as the wind direction, rainwater flow, different salinity and sea water flow in dry and wet seasons .

129
The factors of fluctuation area According to the table salt experiment that we have done, most of the crystallization takes place on the fluctuation area of salt water. Therefore, it is significant to identify the attribution of fluctuation area of the Ulcinj. We have proceeded by diagramming these processes and that resulted diagram shows that the position of the red colour which is associated with higher possibility of crystallization, marks the higher possibility of growth of crystals. The factors of wind direction On the basis of our physical experiments, the side from which the wind enters in the crystallization process can generate more volume of crystals and can, also, affect the morphology of crystallization. In terms of wind direction, we collected the seasonal wind direction of Ulcinj from local bureau of meteorology. Then, showing the specific wind direction on which part of Ulcinj based on this kind of data to merge with the ESA map. 130

The factors of water flow
July Dry season
October When we re-metabolise the cycle of Ulcinj, the pumping system could bring the sea water back into the saline ponds. The blue trace in the diagram above shows that different seasons have different strength of water flow. 134
August
December Wet season
In addition, the diagram illustrates that because of different strength of sea water flow, it would result in a different kind of crystallization pattern. 135

Simulation of Rain water flow in local Ulcinj Regarding to the different height of terrain, it would affect the rain water flow and affect the distribution of salinity indirectly.
138
139
DLA simulation in saltpan of Ulcinj In the reality of Ulcinj, there are many factors that could lead to altering the morphogenesis of crystallization. In this simlation, we selected four key factors such as sea water flow,rain water flow, wind direction and the fluctuational area. For instance, firstly, the wind direction consists of two ways which are the land wind and sea wind. Secondly, the data of waving salt water area was analysed and mapped from the ESA map of NDWI version and the agent of sensing algorithm, which means it does not include the dry area and the area with saline water consistently. Thirdly, when the local metabolism is reactived, the sea water could flow backward into part of Ulcinj, this flow direction, also, could affect the amount of crystallization.

In Ulcinj, there are a number of types of migrating birds habitat in a specific season so that the multi-functional substratum could afford different types of bird nests frames for the birds according to their habits and features.
As for the social sphere, it is significant that turn the plenty of wasted salt material into the useful material in the local cycle. The agent of generating substratum could also create the substratum for the catalytic cells which can produce the electricity for the pumping system, local people and so on.
Regarding to the multi-functional substratum, the activity of bird watching is one of the elements in the urban scenario. The agent could create some space for the human with an unimaginable organisation.

The exploded drawing of actual dimensional substratum. The agent of generating substratum is one of the agents in intelligent material system. The system could generate substratum with the specific code of the L-system. In addition, it includes morphological growing sequences which could produce substratum step by step while the system is computing. Therefore, there are six types of components generated by the agent could create the substratum similar with the logic pattern of composition that according to the urban scenario such as biosphere and social sphere in Ulcinj. For example, the substratum of bird nests was produced base on the propagating habits of local migrating birds so that the dimension of the structure is suitable for the species. Moreover, regarding the social sphere, there are two indispensable activities such as catalytic cells and bird watching in Ulcinj. The catalytic cells occupied at the lower part of substratum which more easily to grow the salt crystals from the saline water whereas the substratum for the bird nests occupied higher space which has more safety.

According to the evidence of the digital crystallization by the DLA system, it is clear to see some different pattern within the different scale of substratum. In comparison, the micro pattern of digital crystallization is driven by the DLA algorithm whereas the global pattern of crystallization is driven by the geometry of substratum.

Halophilic Bacteria Halophiles are one of the ancient bacteria can survive in the saline environment such as sea water, salt lake and the solid product of salt. Also, there are many benefits that human has utilized it nowadays. For instance, halophiles could reduce the salinity of water, filter the polluted material, decomposite of plastic, use for the solar battery and so on. Human might produce the polluted water then emitting into the sea, the river or the saline pound. Therefore, the halophiles could deal with some of issues of urban problems and afford some benefits for the mankind.
