SAFE BOX Preservation of Seeds in the UAE By Danyia Najee
Safe Box
Seeds are a form of life and the foundation of plant kingdom on earth and the food chain. The world is rapidly developing resulting in loss of our connection with seeds, a sacred bond that must be restored “Seeds are the one thing that are the only genuine promise we have of the future” (Shiva 53). To properly re-establish the connection with seeds, greater efforts should be exerted to secure the longevity and well-being of seeds which can be achieved through seed banks/vaults. Although Seed Vaults offer the best way to ensure seed safety and diversity, they fall short on developing crop diversity. In the UAE, crop diversity is absent due to the challenging climate and infertile land, which lead the UAE to be highly dependent on exotic plants that prevent capitalizing on the native plants in the country. UAE can work on enhancing crop biodiversity, lessen dependency on exotic/imported seeds and preserve native seeds in a safe area, despite the challenging environment, for the goal of enhancing self-sufficiency in ways to be further explored in this research.

1.1 Seeds in a Conceptual Approach The Relationship With Humans and Earth
Fig. 1: Seed growth process
Seeds are a form of life. Without them, there would be no source of plant life on earth. One may not realize how much importance a seed holds, with sun, soil and water, a tiny seed can transform into a life giving gift. The seed can be considered as the beginning and the end of the entire plant’s life, it is the soul of the fruit. Once the seed is planted, it starts growing and developing into a plant through the earth’s soil and nutrition, as it develops it eventually matures enough to produce new seeds. The seed is therefore the start and the end, it is what completes the plant’s life cycle. We must understand and appreciate the connection we humans have with seeds, as we are both living on this earth. If we lose our connection to seeds, we lose our connection to earth. Because it is earth that blessed us with seeds. According to author and Sufi mystic Llewellyn Vaughan-Lee, today we’ve lost our connection to the life-giving properties of seeds as a by-product of our highly industrialized and “materialistic” culture. In today’s world, as we buy our packaged products, far away from the cycles of planting, we are drifting away from It is important to think about, and that is how much of a value and impact seeds have in our lives, which will help us to restore the connection we have had (Seeds Are A Sacred Metaphor For Life And Renewal, Say These Faiths). In the past generations, the native people never took the seeds in their land for granted, as they knew they are a precious gift that symbolizes love and trust from the divinities, they knew their lives are dependent on the welfare of the seeds, which

1.2. Seed Technology Even though it is today’s modern world and the globalization it caused, is what lead to a decline in seed biodiversity, thus a loss of connection between us humans and seeds, it also offered us ways in which we can help restore this biodiversity. A field specialized in that is Seed Technology. Before getting into the options seed technology is offering, we must understand what is means. Seed technology to some authors is defined as the following:
“that discipline of study having to do with seed production, maintenance, quality and preservation” (Cowan 1973)
technology as the methods through which the genetic and physical charac-
teristics of seeds could be improved. It involves such activities as variety development, evaluation and release,
seed production, processing, storage and certification (Feistritzer 1975)

In other words, Seed technology is basically an inter disciplinary science that includes a wide range of topics. In its widest sense, ”seed technology includes the development of superior crop plant varieties, their assessment, seed making, seed handling, seed storage, seed testing, seed certification, seed quality control, seed marketing and distribution and research on seed physiology, seed production and seed handling based upon modern botanical and agricultural sciences” (Raikwar 2).

1.2.1 Concept of Seed Technology
To conduct further work on seeds, one must be knowledgeable enough in this field and to know that working on seeds can sometimes be both complicated and tricky. One obstacle the researchers have stumbled upon is the existence of a grain, which shares similar characteristics to a seed. It is important to differentiate between seed and grain, being of seminal significance for agriculture. A seed, strictly speaking, is a "embryo," a living entity that is located in the tissue that maintains or preserves food. The crop relates to the substance (rain, fruit or vegetative propagating substance) expected to be preserved for planting purposes, with reproduction being the central feature. The seed is dramatically superior in terms of seed quality when clinically produced (such as under seed certification), namely Enhanced range, varietal integrity, freedom from weed and other crop seed admixtures, protection of seeds, high germination and vigor, handling of seeds and safe moisture content, etc. On the other side, a grain comprises cereals and seeds intended for human use (Raikwar 2).

1.3. Goals of Seed Technology The main goal of seed technology is to ensure the vitality of the seeds, their high quality and to increase agriculture production, which all can be achieved if the following criteria is met:
1 2 3
Rapid multiplication
Plant breeders develop new varieties that results in a higher quality and quantity of seeds. The time consumed to provide the desired quality and quantity of seeds should be considered as a standard of efficiency and competence in the advancement of seed technology in the country.
Time supply
The new improved seeds must be available in timely fashion so it does not disrupt the planting schedule of the farmer.
Cost
The expense of high seed quality should be beyond the control of the average farmer.
10
Those certain aspects can be done if there are good quality seeds of high yielding varieties (HYVs) are provided. Seeds with high yielding varieties (HYVs) have the qualities of being resilient to diseases, responses strongly to fertilizers, matures early and produces crop of high

Seed Storage
12
2.1 Why Store Seeds? Seeds are made to survive, they are pre-conditioned for continuous reproduction until the environment is suitable for the beginning of a new generation. However, like any other living organism on earth, they eventually stop reproducing and die. Fortunately, both agriculture and nature do not need seeds to last longer than they are meant to, though some species last longer than expected when being under the right conditions. Even though seeds are widely available to us, we should not take this gift for granted. What guarantees the longevity and well-being of seeds is the environment it is growing in, and the environment or climate is an un-stable and risky factor. If there is an imbalance in the soil’s nutrients the seed can be effected, if the farming practices are poor it can lead to crop failure, thus a famine. So many little mistakes can be unintentionally done that affect the life of seeds, that is why need to take measures to preserve them, to ensure the continuity of seed biodiversity and to avoid their extinction. A common method that is done to protect seeds is Seed Storage. Seed storage can be done in many ways, whether it’s by drying

to be stored in certain ways, the two types are Orthodox seeds and Recalcitrant Seeds.
Orthodox Seeds
Orthodox Seeds are ideal for storing. They are long-lived seeds that can endure freezing temperatures and drying with a 5% moisture content only without losing its vitality. By the time they reach maturity, their moisture content is about 30-50%. Some of the most common Orthodox seeds are guava, banana, apple and cherry seeds. (Raikwar 25)

Recalcitrant Seeds
Recalcitrant Seeds are not the best for storing. They are short-lived seeds that cannot handle freezing temperatures nor survive without a moisture content below 30%. Their moisture content is what makes it hard to store because with high moisture content, microbial contamination can be easily caused which leads to quick seed deterioration. And when exposing these seeds to freezing temperatures, it causes a formation of ice crystals,

which mess up the seed’s cell membranes and leads to a freezing injury. Recalcitrant Seeds are found in the moist tropics (Coffee, cacao, citrus) where the moist level is high. They are usually covered with their fruit’s

content is higher than orthodox seeds (5070%) but their embryo size is much smaller than orthodox seeds, it is about 15% of an orthodox seed embryo. Most of attempts at storing Recalcitrant Seeds have centered on the use of endogenous seed inhibitors such as abscisic acid or the substitution of high

Seed moisture
The moisture content of the seed is one of the most important aspects affecting the possibility of the seed’s survival during storage. The increase of moisture range affects longevity of seeds in a negative way as it increases the chance of deterioration. As a general rule, the possibility of seed storing increases in double with a 1% decrease in seed moisture, this applies when the seed moisture range is between 4 to 14%. Problems occur when the percentage of moisture increases (12-14%) and the increase leads to mold growth. Moreover, temperature also plays a role as it’s its increase leads to an escalation in the biological activity of seeds as well as insects and mold. The temperature, whether it is high or low, noticeably has a an effect on seeds with a high moisture content. High moisture content clearly has a huge influence on the longevity of seed. However, very low moisture content has just the same effect. Seeds with a very low moisture content (4% or less) could be injured due to extreme dryness, the dryness can also damage the seed membrane structure. Since it is clear that the moisture content has a huge influence on the life span

Genetic factros
Some seeds of specific species are genetically and chemically engineered for longer storing periods than other seeds under the same conditions. Majority of seeds with a longer life span belong to species with a rough, impermeable seed coat. In general, seed species that contain high content of oil do not survive long in storage in compare to those with a low oil content. The percentage of oil contained in the embryo part of the seed is what is responsible for the quality of storing (Raikwar 26).
Insects & Mites Insects and Mites have a large impact on seeds, especially in tropical climates. Studies show that Weevils, or flour beetles are hardly active under low temperatures (18-20°C) and moisture levels (8%). As the temperature increases to 30-35°C and moisture content goes up to 15%, the more destructive impact the Weevils have on seeds (Raikwar). For an ideal protection from insects and mites, it is recommended to store the seeds at a moisture content less than 10% and at a temperature less than 20°C (Raikwar 29). 20
Pre & post-harvest conditions
Environment factors usually do not have a major effect on the seed’s ability to live and survive. However there are certain scenarios that can have a clear impact on its well-being such as premature harvesting that disturbs the ripening process. Adding to that, seeds that are exposed to extreme weather conditions such as freezing temperatures, extreme heat or humidity/moisture all can severely diminish the longevity of seeds. Mechanical damage inflicted causing in the harvesting process can severely damage the seeds. Mechanical damage simply means the damage caused by the physical processes of handling seeds (Andrews). For example, large seeds such as Cereal are hardly prone to mechanical injury due to their protective layers, lemma and palea. Also, irregularly and elongated shaped seeds suffer much more damage than small seeds and seeds that are spherical in shape (Raikwar 28).

2.4 Storing Methods By understanding the different types of seeds and knowing what factors play a role in their quality and longevity, the choice of deciding which method to follow in terms of storing the seeds should be easier. In general, there are two main methods of storing seeds, it is either Seed Drying or Cold Storage. Each have their own advantages as one works better than the other depending on the type of seed.

Seed Drying According to Bioversity International, a global research-for-development organization, seed drying is the reduction of seed moisture content to the recommended levels for
seed storage, using techniques which will not be detrimental to seed viability
Using the safe techniques is what is essential in this method because it is what will guarantee the seed viability and will avoid mold growth and an increase in micro-organism activity (Raikwar 18). If Seed Drying is done correctly it can achieve the following: 1. Permits early harvest 2. Permit long term storage 3. Maintain seed quality To go deeper into seed drying, it can be done
mainly by two ways. Either Sundrying or
23

2.1
Forced air drying.
Sun drying This is a simple, cost saving method that is done without the use of any special equipment. The first step is done on field by lowering the moisture content of the seed before harvest. Later on, the seeds are left on the threshing floor to get dried naturally by the sun. The disadvantage of this method is that it relies heavily on the weather conditions, which can cause a delay in the harvest. And even if the seeds are harvested under the right weather condition, changed in weather can happen while they’re being naturally dried which could ruin them. Other than weather conditions, the seeds can be exposed to mechanical admixtures which leads to their deterioration. If Sundrying is the method to be performed, the following precautions should be taken to insure the success of the process. 1. The Harvest should not be spread on wet or dirty land (Raikwar 18). 2. Avoid the mixture of crops in order to put enough care and attention into one variety to avoid low-quality production and the mixture with mechanical admixtures (Raikwar).
24
Fig. 13: Sun drying requieries low moisture content, Sun & proper weather conditions
Forced Air-drying In this method, the seeds are exposed to air by force. As the air is put on wet seeds, the water evaporates and results in a decline in both the air and the seed’s temperature (Raikwar19). Forced air-drying has three main methods. 1.
Natural air-drying: This is a simple method
which requires only natural air. 2. Drying with supplemental heat: This method works by raising the temperature of the air in order to reduce humidity. The ideal temperature raise would be to reach 10° C and not to exceed 20° C to avoid a rapid incline in the seed’s temperature which can cause its deterioration. 3. Heated Air-drying: This method is extreme as the air is heated to about 40° C. Heated Air-drying is the preferred method as it is faster and more efficient than the first two. However, it can be a complex process as it requires special drying bins or wagons which are spe-

Cold Storage Cold storage is a method done by storing
the seed in storage area with very low temperatures.
Cold storage is a method that is the complete opposite of Seed Drying. It is done by storing the seed in storage area with very low temperatures. Cold storage is a common method used at seed banks. The process is done by drying the seed enough to reach the optimal moisture content, then its quality and genetic purity is evaluated. It is important to run a background check on the seeds to guarantee that the seeds that will be stored will live long enough and not deteriorate. After choosing the seeds, the last step is simply done by placing the seeds in moisture-proof containers. Even though it is the cold temperature is what makes it possible for a seed to be stored, it is also the exact temperature is what decides on how long the seed can be stored for.
28
Fig. 17: Seeds requiere low tempretures and safe storing in cold storage
According to the Seed Biotechnology Center, For short-term storage, seeds are dried and placed in sealed containers at 5°C. They are stored at temperatures below freezing for long-term preservation (0°F or -20°C), including the use of cryopreservation, or freezing in or over liquid nitrogen at -180°C, for extremely long-term storage (Seed Storage/Conservation). However, even when put under the perfect cold conditions, the seed’s viability can decline over the time. That is why it is extremely important for the seeds to be removed out of storage and used to produce a new crop of seeds (Seed Storage/Conservation). When it comes to cold storage, it should be kept in mind that it does not work for all types
30-50%
of seeds. As mentioned previously there are two types of seeds, Orthodox and Recalcitrant Seeds. Recalcitrant Seeds are short-lived seeds that cannot handle freezing temperatures nor survive without a moisture content below 30%, this means that Recalcitrant Seeds cannot be stored successfully. The only way to guarantee the longevity of Recalcitrant Seeds is to work

With cold storage being the ideal and most preferred method in Seed storage. It is worth to mention the one of the best facilities in the world to store seeds is the Svalbard Global Seed Vault. Located on a remote island halfway between mainland Norway and the North Pole. The Svalbard Global Seed Vault currently holds 1,057,151 samples from all over the world and has a 4.5 million variety capacity and requieres a minimum tempreture of -18°C. The Seed Vault is the best way to ensure seed safety and diversity.

Adding to the topic of cold storage, it is not only the preferred storage method for seeds, but for other fields as well, such as Gene banks. Gene banks are a type of biorepository which

After conducting research on seeds, looking at how deep their roots are imbedded into earth makes much more sense now. This symbolizes how deep and complex seeds are. As we look at plants that surround us here in the UAE, we must now wonder the odds of those seeds surviving storing.

geological zones; Mountains, Coastal lowlands and the biggest par, the desert. The mountains in the UAE cover a small portion of its area. They start from the northeast of Dibba to the southeast of Al Ain. The coastal lowlands stretch along UAE’s western coastline, which covers 6 out of

the 7 cities in the UAE. And with the UAE’s total area of 83,000 sq. km, 80% of this area is covered with the third geological zone, the desert, thus where the lowest amounts of rain is.

The mountains receive most of rain which is about 153.1mm while the desert receives about 86.1mm. Since the country’s major part is the hot desert, and it being the lowest receiver of rain, it is expected that the country’s plant life would suffer, because the extreme temperatures and the low rainfall have a direct effect on the soil of the UAE.

3.2 UAE & native seeds
The harsh environmental conditions surrounding the UAE have a great effect on all flora and fauna. Due to the limitations of plant species that are able to survive in such conditions. It is rare to have naturally occurring plants in this environment, and even so those species are subject to extension. Therefore, numerous efforts should be taken to conserve those plants

in order to manage them sustainably. Sharjah Seed Bank & Herbarium is a facility located in Abd Dhabi, UAE that is dedicated to this matter. The Sharjah Seedbank and Herbarium (SSBH) is a research facility that is part of Sharjah Research Academy that is focused on exploring and securing UAE’s flora outside of its natu-

ral habitat. It has herbarium collection spaces with 4500 samples from different regions in the country and houses samples for more than 50% of UAE’s flora. Adding to that, it stores around 1710 native seeds. SSBH also focuses on the

research of genetic diversity and the DNA barcoding of UAE’s flora. (“Sharjah Research Academy”) The facility’s efforts towards the conservation of UAE’s native plants are significant and more light should be shed on their work.

However, the facility’s work and field of focus lacks some aspects that can be vital towards the safety of UAE’s plants and the country’s biodiversity. First, the facility’s work is primarily focused on local or native species in the UAE, it works on storing them and learning more about them. It is focusing on what we have now, the present, rather than the future. With the current climate crisis that the globe is facing, it is clear to us by now that the conditions we are in will not stay the way they are. And it terms of climate change, it is only getting worse. Since the UAE’s climate is harsh and has been proven over the years that it is getting worse, it is already hard for some plants to survive. According to the statistics of the Ministry of Environment and Water, the UAE has witnessed an increase in its temperature over the past 30-40 years. The temperature increase was recorded in all 7 emirates and the averaged between 0.6

3.3 UAE’s Biodiversity
Although the government is putting efforts into preserving the seeds, it is not being mindful to the shift in climate. So instead of taking measures into insuring their safety by preserving them in safe storages, why not explore and work on ways that can make these plants adapt to the harsh conditions? And what is more important, why not engineer their seeds to adapt to even worse conditions? The worst case scenario should be taken into consideration, which is why the storing method should also be one that guarantees the longevity and vitality of the seeds for a long period of time. As discussed in chapter 2.3. the ideal storage method is cold storage. Depending on the temperature used, it will determine for how long the seeds can be stored for. The Sharjah Seedbank and Herbarium (SSBH) mission and aim is to conserve UAE’s native plant biodiversity for present and future generations but it is not using one of the most suitable ways to do so, cold storing. There must be a space dedicated to that matter not because it is one of the safest methods to guarantee the longevity of the seed, but because it also works on UAE’s native seeds. However, as explained earlier, cold storage does not work on all types of seeds, the Orthodox and Recalcitrant seeds.
46
Orthodox seeds are long-lived seeds that can endure freezing temperatures and drying with a 5% moisture content only, while Recalcitrant seeds are short-lived seeds that cannot handle freezing temperatures nor survive without a moisture content below 30%. The UAE has a number of Orthodox seeds such as Wheat, Tomato, Cucumber and Eggplant. In knowing so, one might say that using cold storing facilities in the UAE does work and should be implemented. Even though cold storage facilities are recommended to guarantee the life of seeds, and is in a way sustainable because it works on preserving something that already exists instead of wasting natural resources, money, time and effort into developing something completely new. It is however unsustainable it terms of working with UAE’s climate. Cold storage requires very low temperatures that in many times can reach below zero, and by knowing UAE’s hot climate, even in winter the temperature does not drop to that extent. To be able to achieve cold storage facilities in the UAE, a lot

3.4 Landscaping in the UAE In order for the maximization in effort, ways and efficiency of the current storage and research policies in the UAE and the methods used, what it would be receiving in terms of seeds or plants should be enough to make the establishment of such facilities possible. The thing about UAE’s desert ecosystem is that it has low biodiversity, with high temperatures and low rainfall comes low biodiversity. Despite the extreme arid conditions, the UAE has more than 700 plant species from diverse habitats, whether they are for cultivation or not. But with the increasing population in the UAE, its desert and other geographical zones are being occupied with huge urban and landscaping developments. This erosion lead to an endangerment to the biodiversity of the UAE and has put it under the threat of extension. Therefore, the number 700 does not seem to be as diverse as we thought. Adding to that, the flora of the UAE has be given very little attention (Jongbloed et al.). To cope with the urban developments in the country, the establishment of greeneries and beautiful urban landscapes is required. The problem lays here as most of the urban landscapes seen around the UAE are composed primarily of non-native species.
48
Non-native plant species are a burden to both the economy and the environment. Because those exotic plants are mostly imported from temperate or semi-temperate regions to a hot, dry climate they require high maintenance and need an extensive support systems in order to adapt to the major change and to keep them alive. Moreover, they require high irrigation requirements and a significant amount of care by the gardeners to establish the aesthetic views Non-native Can adapt
that are inspired by western landscape designs (Frenken). The heavy reliance on exotic plants causes a loss in UAE’s original plant and seed biodiversity. Adding to that, it causes a confusion in not knowing which plants are native and which are non-native. The main problem here is not the use of non-native plants, non-native can mean two things; plants that are brought to a country and have no potential of adapting to the host country’s climate conditions, in other words, exotic plants. The other type of non-na-

3.5 Growth in UAE’s biodiversity As the excessive reliance on exotic plants in the UAE comes with a high cost and threatens its biodiversity, more care and effort must be put into the native species in the UAE, and as mentioned previously in chapter 3.4, with the relatively low biodiversity the UAE has, chances are what the exotic plants are doing in terms of beautifying the urban landscapes would not be as successful when using native plants. The solution to this would be to introduce more species into UAE’s flora in a sustainable way. Plant species are divided into three main sections namely native, naturalized and introduced.
1
Native
2
Naturalized
3
naturally occur within the UAE
species that are from outside the UAE but can be found growing within the UAE in many locations.
Introduced species that are non-native but with only single or few records within the UAE and these species have the potential to become naturalized.
52
The focus here would be on the Introduced species, bringing more species from similar climates would increase the biodiversity of UAE’s plant life and those new species would be necessarily considered ‘exotic’ as they fit into UAE’s conditions. This method has been proven to work as some research has been already done on this matter regarding the grasses in the UAE. The table below lists some of the native, naturalized and introduced grasses in the UAE.

3.6 Salinity in the UAE By learning ways in which we can increase UAE’s biodiversity without the use of Exotic plants, what makes them exotic is their inability to adapt to UAE’s harsh climate, and what makes the Introduced and Naturalised plant’s implementation successful is how their characteristics are similar to the native plants, they adapt well with heat and low rainfall. But the most important aspect is their adaptation to salinity. A lot of regions are hot with low rainfall, but that does not mean they suffer from high soil and water salinity. Salinity refers to the level of salt in the water and soil, it is a common aspect in arid environments, like the UAE. Plants in arid environments are categorized in two groups: Xerophytes and Mesophytes

56
Salinity is a serious issue that faces the land of the UAE. According to the estimation by The Food and Agriculture Organization of the United Nations (FAO), in 1994, 12% of UAE’s land was affected by salts from various origins. And recent studies show that 25% of the area is now affected by salt. The high levels of salinity does not mean that plants are no longer capable of growing in such lands, but the plants chosen must be suitable for this environment. Halophytic plants could possibly be suitable for growth in those lands. As the salinity plays a major role in UAE’s environment and has a huge impact on its biodiversity, it is a deeper issue that one might think. But by having enough knowledge about it we would be able to know which species would be able to survive in it or not. And with that, it would ensure the contin-

Project Brief
The Botanical Research Institute of Texas is an international scientific research and learning center focused on conservation and knowledge sharing. BRIT has a variety of functions that all serve the purpose of plant research and conservation. Concept
The concept behind BRIT is to provide a space that is focused on conservation and knowledge sharing of plant species. BRIT provides housing administration and research offices, education department, exhibit area, and public spaces, and the “Archive Block”, housing the herbarium and library. The design of BRIT also corresponds with its idea, BRIT aspires to reduce its footprint on the natural world as well as protect and restore ecosystem services, it does that through the smart design of the building. BRIT building includes Sustainable features such as stormwater management, geothermal wells, solar panels, reclaimed and recycled materials, a green roof, and many others. 66

Materials
BRIT consists of one building with two
departments, the Think Block and the Archive Block, both exteriors are a reflection
of
the
department’s
function.
Think Block is a two story building that includes administration, research offices and an education department. Therefore, the building›s exterior is a combination of precast concrete panels and glass, with most of the glass located on the north side to bring in most of the light with no direct exposure to the harsh sun, and few openings on the south side. As the building is characterized for its sustainability features, the narrative continues even in its use of materials. Recycled Content Materials were used for over 20% of BRIT’s building materials. Structural steel and steel pipes are one of the many reused materials. And the building’s rubber flooring is made out of recycled tennis shoes and other rubbers like tires and single-ply roofing membrane.
The Archive Block houses the most important part of BRIT, the area where the botanical specimen is collected, sorted and stored. Due to importance and the delicacy of the botanical specimens, they must be stored in a safe, climate controlled area. The specimens are stored in a two-story storage hall, that is a solid box of concrete panels with no windows to provide maximum temperature and humidity controls. 72

Circulation
The circulation in both buildings is mostly linear. The main entrance is located in the
center of the Think Block. The entrance is highlighted by its double height and grand staircase with the reclaimed sinker cypress wall, on both sides of the entrance the main functions are located, leaving the back of house on the ends of the building, the east and west side. The main corridor is longitudinal and located on the south side, the static and defined arrangement of the spaces is what shaped the corridor. The majority of the spaces are closed and the circulation between them is either by the main hallway of the narrow corridors in between. However, the monotony is broken by having terraces after every program.

The spaces are distributed based on how private they are. On both sides of the entrance, the public functions are located such as the gift shop, bathrooms and exhibition space. As you go deeper into the building, you start seeing the more private spaces like the library or administration office, or spaces accessible by employees only like specimen processing room and loading area. In the Archive Block department, it houses the collection management, which a combination of public and private spaces. The public ones are placed on the sides of the corridor while the private ones (mostly for employees) are deeper inside.

Project Brief
Located in the cities most visited space, close to the Avon River, Christchuch Botanic gardens is considered one of the most significant projects since the earthquick that hit christchurch in 2011, the center was dedicated to allow the garden to conduct research on plants and plant biodiversity and to run educational activities all in a space that shows the beauty, variety and complexity of the plant world.
Concept
The concept behind Christchurch botanic gardens is to connect people with plants by creating a space dedicated for people and plants (greenhouse). The building’s design is inspired by the traditional garden glasshouse structure. The space has a variety of functions encourages the connection between the people and plants, starting with the visitor center that includes a greenhose, then a cafe, research laboratories, propagation rooms and many more. 86

Key Element
Form & Roof Design
The building’s glass form has been devel-
oped from a modular commercial greenhouse system. The building plays with trans-
parency, mirrored reflection and the layering of fritted glass to display the workings of a botanic garden while subtly providing staff-only areas. The form also plays a role into the disturbution of space and marking its importance. It starts with public, then semi-public and private. The glass ceilings and skylights form a varied, leafy-like canopy shedding dappled light to the interior. And The installation of the saw tooth roof took four years from start to finish due to the interruption of earthquakes.

Materials
The building’s exterior is characterized for
its light transparent material to enable the
visitors that are not even inside the build-
ing to have a sort of a connection with the inside, the tarnsparency of the crystalline glass gives a light-weight feeling to the building which is essential as it is surrounded with the nature, trees and a nearby river. The building’s material mainly depends on the spaces provided inside. The building has three main spaces. The public space’s facade is crystalline glass, the semi private is a combination of clear and fritted glass. In the interior, some walls are made out of a plaster with a unique pattern that contiues all the way to the false ceiling. However, the pattern in the false ceiling has hollow spaces in between, to allow the sunlight to enter the space through the glass ceiling.

Circulation
With the building being disturbuted into 3 main zones, public, semi-public and private.The
transition into these zones is what defines the circulation. The public space is the main
zone as it includes the main enterance, and the functions in it are public however they are defined by walls. So the circulation starts out by being free and very open, then it gets more defined as the functions have 1 or 2 accesses only. In the semi-public space, it mainly consist of the greenhouse and the shade house which include the plants, and due to the distribution and the layout of the plants, the circulation is defined through the linear corridors in between the plants. In the private space, it included offices and functions that are mainly for the employees, so as the offices and closed areas are placed next to each other in a linear way, the corridor is also one long linear one.

The Australian PlantBank, located at the Australian Botanic Garden in Mount Annan, is a science and research facility of the Royal Botanic Gardens and Domain Trust. It houses the Trust’s seedbank and research laboratories that specialise in native plant conservation. The facility is positioned globally as a symbol of preservation of the natural cycle from the germination of seed to the propagation of forests. Concept
The concept behind the Australian Plant Bank is to create a research facility dedicated to the Australian indigenous seeds while embracing the nature of Australia. The selection of the site, has influenced the form of the building it embraces the remnant endangered Cumberland Plain forest to the north; as the natural character of the forest transitions to the cultivated landscape of the “embraced” courtyard the building literally reflects the merging landscapes. The dialogue between the transitional landscape and the building is a metaphor for the mediated and cultivated land of Australia. 104

Key Element Sustainability
Sustainability at PlantBank continues the engagement of the building and domain with its
natural setting. The plan arcs to the north placing the maximum amount of visitor fa-
cade to the sun which is then moderated by a deep wall enabling sunshading. The depth
of the wall also facilitates all weather operability of the glass louvres in the public areas and the workplace. In the workplace, with an open plan spanning from east to west, cross ventilation is assured for a considerable part of the year. The mixed mode facilitates a lesser reliance on mechanical plant resulting in significantly diminished energy consumption.
A thermal labyrinth has been installed under the east wing which reduces the HVAC load and extends natural ventilation,
The system is designed to reduce the peaks and troughs of extreme ambient weather by capturing either the heat of the day or the cool of the night retaining it in the surrounding concrete, earth and rock beds of the constructed labyrinth.

Materials
The building’s expression is derived from this visceral relationship between built form and
the land - the concrete base nominally the abstracted earth; the polished stainless steel panels diluting and making ambiguous the
relationship between the built and natural settings; the operable louvres enabling mixed
mode ventilation sealed by stainless steel bushfire mesh; and the form of the building in both plan and expression being deferential to its natural setting. The workplace of the researchers and staff is in a mixed mode environment. Interior finishes have been chosen to articulate the different characters of the building - the laboratories and interpretive areas having visual clarity with the workplaces designed
with timber and a softer working environment.

Circulation
Going under the east wing of the building - nominally passing under the ground - the building curves to the north and merges with the land toward the extant forest. Walking to the front door the visitor engages the interpretive display that connects the external courtyard with the internal research. The main enterance of the building is located on the north side, to emphsize the connection
between
the
building
and
the forest even more, and from their the the visitor path runs beside the clear glazed laboratories with the external interpretive material focussed on the activities within the labs. In the plant bank, majority of the functions are disturbuted in seperate, enclosed spaces. Therefore, the circulation in those spaces is defined by the walls and the diturbution of the funiture.

Program
The plan has been derived in response to the brief and to the strong natural context. The brief calls for a building of dual function - firstly a place in which research into Australian indigenous seeds will be conducted and a repository of seeds is housed and secondly a facility revealing research through public interpretation and exhibition activities. On the ground floor, cold storage rooms are used for preserving rare and endangered plant
specimens,
trolled
banks
and
stock
temperature-con-
indigenous
seeds.
A drying room, processing area and incubators for young seeds are also located the ground floor, along with an underground thermal labyrinth that reduces the risk
of
harmful
temperature
fluctuations.

Site Context & Analysis
128
6.1 Site Selection For my site selection, my focus was on green spaces around the country and specificly, natural green areas with the least human intervention. With the UAE’s extreme climate, it is hard to find green spaces without any human interference, as the trees, even the local ones requiere minimal amount of care. Adding to that, i wanted my site to reflect the purpose of my concept which circulates around the preservation of UAE’s plants and seeds. Therefore, the areas i looked further into mainly comprise of local trees and with the least artificial greenery and landscaping. To decide which site would suit my project the most, I created a judgment criteria to help me and the site chosen will adhere to these points:
Landmarks
Area accessibility
Historical context
Number of trees
129
6.1
6.2
Activities on site
To begin my initial site selection, i chose two opposite cities in the UAE, Dubai and Al Ain. Dubai is known for it for its superficial
skyscrapers
and
exotic
greenery
while Al Ain is known for its calm environment, its palm groves and natural springs.
130

Fig. 105: UAE map
To get deeper into the analysis, i then selected areas in the two cities which are known for their natural greenery, which is my main goal in the site selection. In Dubai, i picked Mushrif park. And in Al Ain, i picked Al Ain Oasis and Al Jimi Oasis Mushrif park is one of the oldest major parks in Dubai that is known for its use of local trees. While both Oasis in Al Ain are known for their continuous planting of local trees

Mushrif Park
Mushrif Park is one of the oldest major public parks in Dubai, as it was established in 1974 over 125 hectares. In 1992, vast areas totaling 575 hectares were annexed to the park. These areas are currently being used as a natural forest, where diverse types of local trees are planted, totaling to more than 70,000 trees, in addition to the trees naturally present in the region. Mushrif Park has gone through several developmental stages, the last of which was in 1989, where it was inaugurated during the festivities of the eighteenth National Day celebrating the establishment of the United Arab Emirates. The park is located in Deira, Mushrif area, about 15km from downtown Dubai, on the Airport Road road leading to Al Khawaneej, facing Al Mizhar 2 Residential Area.

Al Ain Oasis
Covering 1,200 hectares, this lush oasis provides a unique insight into the region's inhabitants who began taming the desert 4,000 years ago. Located in the centre of Al Ain, Abu Dhabi's garden city and heritage heartland situated about a one-and-a-half-hour's drive away from the capital, this is the largest of Al Ain's oases. Farmers tend to thousands of date palms of 100 different varieties, as well as fodder crops and fruit trees, such as mango, orange, banana, fig and jujube (known locally as sidr). Individual plots and working farms are separated from each other by historic boundary walls.

Jimi Oasis
Al Jimi Oasis is not only an agricultural area with a thick cover of palm trees, but also contains mosques and fortified houses that speak to the agricultural and administrative importance of the oasis from the 18th century onward. There are more than a dozen historic earthen buildings in the oasis, including forts and watchtowers that were built in part to protect the falaj irrigation system, which uses underground water canals to bring water from the nearby mountains to the oasis palm plantations, fields and gardens. The oasis sits in a sunken basin that is divided into a series of palm gardens. In addition to the palm trees, fruit trees grow under the palm canopy. In the past, fields around the outer edge of the oasis were used for winter cereal crops, and beyond that was a zone for animals to forage.

Based on the total score, it shows that Mushrif park is the most suitable site to chose. Because of its location which is situated close to residential and mixeduse areas, which gives the opportunity for my project to be exposed to many categories as possible. Adding to that, with the different activities available in the park such as horse riding, cyclying, swimming pool.. etc. That is an advantage as it guarantees the involvemnt

7.1 Summary
After conducting this deep research on seeds, I now have a better understanding on their philosophy and complexity. Seeds can not be simply “stored” for later use or for future generations. One must understand how a seed adapts to its environment, surroundings and everything around it. By realizing its importance, I think it is vital to provide spaces dedi-
165

cated for research on seeds and their storage.

8.1 Mood board
8.2 Concept 1: Berm The idea behind this concept is to take advantage of the Park’s topography to create secluded spaces the are visible from within the park only and to place the most important space in the project, the seed storage/vault underground. This symbolizes the life of a seed as it starts growing underground and branches up.

8.3 Concept 2: Reveal This concept’s idea is to follow the topography’s natural anatomy and to go against it. Following it is done by placing functions within it, and against is by exposing the spaces, the serves the project as it gives it a chance to be exposed to the outside and not just the park visitors. Going inside and outside the topography provides a harmonious transition between the outside (city) and the inside (park).

8.4 Concept 3: Connect The last concept is a combination of both concepts. It works on engaging the city with the park with respect to the park’s natural topography. However, the most important function in the project, the Seed storage works against the topography in this case, it opposes the seeds life cycle which starts from down to bottom. By exposing the seed storage in this way, it would grab more attention and show a clear visual hierarchy between functions.
