Play in Cool

An outdoor park that provides cooling for children to play, Baltimore MD

Fall 2019 Individual Project Instructors:

Marc Miller, Travis L Flohr

Urban heat island is a serious and growing threat to public health, and the warming climate only increases the problem. Baltimore’s urban area is covered with a high rate of impervious surface and fewer canopy trees, which raised the surface temperature, especially in the region with a high density of the imperious surface. Hot climate brings higher levels of pollutants into the air and triggers asthma symptoms, particularly in the children’s group.

My design aims to give back the outdoor playground to the neighborhood children by creating an exterior space where a region with a poorly built environment for high heat and a high asthma disease density. My design intent is to create a park that functions as an outdoor cooling space for children. So, children can play in a clean and pleasant outdoor environment during a hot summer day.

To materialize the climatic condition, the project is invented by a catalog of climatic devices, both natural and artificial. They function cooling and depolluting. These devices are classified into four elements: shade, water, wind, and depolluting. A healthy outdoor gathering space plays an influential role in enhancing big metropolitan cities’ well-being and health. It is an outdoor area where you can have a good time from the excessive heat; where you can relax from pollution and noise; where you can have fun in the open air with children.

I’m a father; I like to have fun with my kid on this rotating bench. Simultaneously, I can do exercise after a long day!

I’m a resident nearby; After plant these trees, the street is much cooler than before! More people would like to go out on a hot summer day!

I’m a student from Highland-town school. just heard our science project exhibition location holds under the Breeze Canopy in the new cooling park. And there will be a lot of visitors from the street!

I’m a biker; always stop here to rest and enjoy the cool breeze during a hot summer day.

I’m a fan of the mist cooling system; It’s 95 degrees outside, but right here, it feels like 20 degrees lower because of the tree covers, breeze, and mist cooling. Do you know the mist system can decrease dust levels that come along with the summer months?

I’m a student from Highland-town school. enjoy having a pool just 400 feet beside my school! Now can come here to wait for my parents to pick me up after school. And do you know this pool can turn into an ice rink in the winter!

I’m a worker; the cooling park is my everyday stop for lunch.

I’m a mother; feel much more comfortable to sit at the right angle to watch my kids play on those mounts!

I’m a resident nearby; the smell of honey and lemon peel reminds me of this park every time! It must be these lovely trees!

I’m a father; When take my kids here to play on a hot day, will sit here, read a book, and enjoy the breeze.

I’m a student from Highland-town school. love to play with these interactive fountains. It requires two people to step on the device to trigger the system and release the water. made a couple of friends by collaborating with them on this device!

Women’s livelihood and cultural practices in Maldives

Fall 2022 Team Project

Li Yan, Anchita Mirwankar

Instructors: Duarte Santo

Maldivian encounter inequalities in many ways, such as displacement, work, region, and gender inequality.

Women’s distribution in the Maldives reduced enormously in the past 20 years. Northern and southern have a higher distribution ratio of women than the middle of the Maldives. Though high in the women population, lower the purchasing power.

For rural Maldivian women, problems like sexual harassment, personal safety, societal stigma, and male-dominated industry make it harder for women to enter work. Female Maldivians is particularly valuable to climate change. Most rural women depend their livelihoods on climatesensitive resources, such as farming, gardening, reed weaving, handcrafts, coconut picking, and fish processing. If women are the most vulnerable group to climate change, we can pick it up to compare our relationship with nature and our relationship with each other. So that nature is more likely to be understood. It cannot be saved by design or hightech alone. It is more about the user’s needs and sustainability.

Even though climate change cannot be solved in the short term by a part of people, but we can stimulate a movement. A movement to the world of how frontline women fight climate change while fighting for their rights. Women and nature can be compatible properties; it is an important theory moving forward to change the relationship between man and nature. And the most important part is we remember the existing condition because it is part of the original, including the history and culture of the Maldives.

Statistics of Women’s Population

Women’s distribution in the Maldives reduced enormously in the past 20 years. The geographical disparity is observed; northern and southern have a higher distribution ratio of women than the middle of the Maldives. Though high in the women population, lower is the purchasing power. Overall the total population of women is reducing because of the rise in men’s migration for job opportunities in the middle Maldives. Moreover, the foreign female population is lower than the local female population.

Thundukuna is a special mat woven from reeds’hau’ indigenous to the marshlands of Maldives.

They were used as royal gifts from the sultan of Maldives to the Dutch and British governors of Sri Lanka. Low income

Two hundred years of long history is mostly associated with the southernmost atolls.

Process of Mat Weaving

1970s - imported cheap plastic mats have replace d expensive local mat

Quality downplay due to present generation of weavers lack of knowledge of reeds/techniques Low productivity

2012- only three women were active growing and drying reeds, and with a lack of enthusiasm.

Youth feel the remuneration is not on par with the hard work.

Power Relationship

The interdependency between Coral, mangroves, seagrass, local reed, coconut palm is threatened by climate change.  Meanwhile each aspects provide an opportunty to empower the local women from inequities and climate change.

Exchange of goods and skills

The floating wetland Technique can be further used in similar wetland conditions to accelerate the reed growth and create an environment for ecotourism for nearby resorts. The opportunities of exchanging knowledge by trained women to nearby islands spread cultural awareness to tourists and locals. Network building can also create direct connections between manufacturers and international retailers, airports, and resorts to maximize sales.

Tapping Device #4 Start

Climate change impact islands with flooding creating a range of issues like affecting reed, agricultural produce, etc. The strategy helps to conserve and produce Hua reeds by proposing a floating wetland technique. It increases the production of reed growth but helps to filter water, attract biodiversity and habitat, and attracts visitors. The floating wetland park floats over not more than 1 m water depth, have restricts the extent of growth. The combination of wetlands with floating pathways and decks made of recycled plastic is proposed for recreational activities.

This initiative allows international participation and empowers everyday people to join the global effort against climate change. People can track and locate their trees through their phones and visit their trees when they travel to Maldives.

Sandbanks are formed overtime because of sand shifting events like channel effect, ramp effect and wrap around effect. These effect constantly shape the island shapes and can be potential for future expansion

Inspiraed by a project of MIT Lab. The accumulation of sand is done by using a ramp that is partially submerged in the water; when its placed strategically, water passes over the ramp to create turbulence at the base. Over time, sand is accumulated a small distance away from the ramp.

Locals test the idea of sand shifting to grow the islands which can be used for coconut planting, and mangrove plantation, creating cultural hubs by attracting tourists to engage with locals and can help to tackle climate change.

Joshua Frank Cerra

“The Hudson River estuary is remarkably scenic and biodiverse. From the Federal Dam at Troy north of Albany to the Atlantic Ocean at New York City, this river is tidally influenced. Daily the river switches from downstream flows to upstream currents twice a day, while subject to hurricane surge and storm impacts from the local watersheds that drain to it.

Through an investigation of the Hudson River Estuary at scale, we can begin to understand which landscapes can serve as (current and future) ecological strongholds, while others provide the connective tissue linking many other wetland types up and down this 150 mile corridor. As these places transition with climate change, we can then orchestrate new relationships to assist the landscape in transitioning the diverse community unities of people and place that make up this region.” (Cerra)

Ramshorn Livingston Sanctuary is defined as the layering of sedimentation, erosion, tidal fluctuation, plant growth, and animal migration. The complex interaction of these processes results in a site that in a constant state of flux.

This project investigates new methods for designing tidal systems using architecture tools to maximize ecological processes. The intention is to test the idea of accelerating sediment accretion to pace up the rate of sea-level rise. Meanwhile, responsive datums deliver didactic dialogues and connection between ecological processes and human use.

Adjustable weir during flooding events

Daily tidal flooding

-The weir will not be constraining flow on daily tides because there is roughness in my marsh with vegetation that can help slow the water and catch sediments.

-It will go slower down the daily tides. About 10-20 mins daily. It may not be something. But It adds up to be something over the years.

-The weir controls floor events to allow more time to deposit sediments in the water.

-According to Hudson River National estuarine research reserve, an area like railroad causeways along the shoreline, the accretion rates two to three times the rate of relative SLR. Generally, gain sediment and elevation at a rate similar to SLR. In addition, we are capturing the sediments from flooding events.

A canopy walkway to educate and raise people’s awareness of the importance of natural reserve, Magombera Nature Reserve, Tanzania

Fall 2020 Individual Project Instructors:

Larry Gorenflo

The Magombera Nature Reserve was created to preserve the unique lowland forest in central Tanzania and sustain the nexus between two prominent national parks. There is a swelling population of communities residing in villages alongside Magombera Forest Reserve. Most people in the surrounding villages are a substantial proportion of migrants, who were drawn to the region by the rich lowland soil and agricultural opportunity. Social and economic aspects of life are both reliant on natural resources and are marketdriven. Villagers perceive their neighboring natural environment as being a source of tangible capital. The level of immediate dependency on communities’ environment from all of the neighboring villages is profoundly notable. There is a significant demand for widespread environmental awareness so that people are more aware of their impacts on the surrounding land, especially being next to such an important ecological area.

Moreover, the Magombera Nature Reserve is home to many rare and endemic species. However, there is currently no infrastructure within the forest to allow humans to interact with the species there safely. The lack of tourism in the area and the need for more economic opportunities allow for a forest design opportunity. How can we execute tourism properly without disturbing the organisms’ habits to reach a high tourist flow to stimulate the economy?

A canopy walkway takes people up to 20 meters that focus on various species in different elevations. The birds’ flighting patterns inspired me; I integrate six flighting patterns into the walkway; each has unique experiences and activities for different groups that tell the story of the local fauna and forest qualities. My goal is to use forest resources to raise people’s awareness of the importance of natural reserves. Meanwhile, increase job opportunities and wage-earning and improve the economy for the widespread poverty in this region.

Flapping Flight (Bird Educate)

When birds are flapping their wings, allowing themselves to maintain height or climb, this method includes down-stroke and up-stroke stages. I’m visualizing the up-stroke in this project.

Phase I

-The walkway is situated in the preserved forest.

Proposed Visitor center building

-The proposed road is along the forest edges to avoid the disturbance of the cropland. Visitors will need to go through the proposed visitor center to get on the canopy walkway.

Bounding Flight (Elevated Walkway)

Small birds often fly long distances using a technique in which short bursts of flapping are alternated with intervals in which the wings are folded against the body.

The ‘Waggle’Extracting the ecologies of production and consumpation, A Memorable Meal.

Fall 2021 Individual Project Instructors: Zaneta Hong

If there is a magic code to the composition of nature’s biological chain, bees are the master craftsman of cracking it. They are plants’ survival factors, the indispensable link in the ecological system. They made products more diverse and of higher quality, contributing to food security and nutrition. Without bees, there would be no fruit and seeds, and the whole ecosystem would collapse.

The value of living things cannot be based on human evaluation but must depend on the value of living things themselves. Bees are essential part of the plant. In recent years, environmental deterioration, climate change, excessive use of chemicals destroyed the habitat of bees. Bees have disappeared in many parts of the world and have completed vanished in some areas.

My memorable meal was Italian based, cooked by an Italian professor. As an immigrated Italian who grew up in NY City and then moved to Pennsylvania, he always talks about the old NY City and hometown food that makes him feel nostalgic. The meal includes cheese plate, Caprese salad, grilled lamb chop, vegetable, corn, red wine, Italian-style fruit salad, and fig dessert. 80% of ingredients in my meal are pollinated-crops. while most of them pollinated by bees. This indicates bees are an essential part of the supply chain. The meal exists because of the bee.

By understanding the life cycle, environment, habitat, flower visitation, migration movements, pressure, conservation, design, etc., of a bee. This table intends to present, experience, better understand, and educate the contemporary from a bee’s perspective.

As members of earth, an entity with intrinsic value, we should be morally concerned and protect the good of non-human living things. We can be not part of nature but are part of environment.

Bee means life.

It wasn’t the fanciest food I have ever eaten; it was the most delicate Italian meal I ever had. And it was a dinner with a recently retired chemistry professor, Dr. Tom, which we met through the classical music club. A friend and I were invited to the classical music concert and dinner after at his house. We sit on the sofa in his backyard that surrounded by a well-planted landscape garden. The house located on halfway of a small hillside, cover with masses of maple trees. We sit and chat under the shade; the place is covered by an arbor structure with flourishing vine plants. After, we moved to this beautiful hand painted Italian volcanic stone table on the other side of the backyard. Colorful plates, antique silver utensils, table napkins, and shining glass were well distributed on the table. On the side, the black iron chair is covered with a brilliant blue color pad, stylish.

A single honeybee collect 1/12th teaspoon in its lifetime, end of the year, a whole colonies collect about 60-100 lbs of honey in order to get through the winter.

To see the simplicity in the complexity in this system. We plant more flowers, we turn the hard pave into flower-based landscape.

The 1/12 th teaspoon matters. With everybody’s help, we can grow the food, plant more flowers that over grow the system.

After removing turf and weeds, apply organics in mid-to-late Fall (soon after leaf fall, but before soil freeze-up) uniformly pread 2” layer locally-obtained organic compost over all areas to be seeded, then spread 6” layer of settled mixed oak/hardwood leaf litter over the same area. 7.2. chisel plow incorporate leaf litter and compost to 12”- 14” depth. ensure soils are moderately moist (not muddy, not dusty dry) prior to tillage to achieve adequate mixing 7.3. chisel plow once more to 12” depth, but this time in direction perpendicular to line of first pass. 7.4. offset discing (or, ‘disc harrowing’) takes place: use an offset disc to complete organic mixing in top 6”-8”, layer one pass enough, soil lab calls for fertilizer (for Mesic and Rain Meadows only!), spread fertilizer first, then incorporate during this step, do not fertilize Prairie Meadow zones. 7.5. Culti-packing or rolling takes place to firm the seedbed just prior to seeding 7.6. Immediately after seeding, incorporate seeds into seedbed using one more pass of the culti-packer or tow-behind roller (for WSGs), or chain-link fence drag mat (for CSGs).

Seed and plug arrivals and installation Installing the seed general 1.1. only seed into workable, moderately moist soil with well-prepared seedbed (see Lecture #1 notes); never seed into dry-dusty wet saturated soils 1.2. alternatively, WSGs can be “dormant seeded” – broadcast in midto late Fall and allowed to break dormancy naturally over winter usually with an annual rye winter cover. But we aren’t recommending this to OPP 1.3. Do NOT seed or plug during mid-June to late August, and do not seed during any draught period Warm season Grasses and Forbs 2.1. Truax grass drill is built for WSG seeding (fluffy seeds) 2.2. note the separate small hopper for heavier smoother forb seeds, to keep them separate from grass seed 2.3. use specially-designed Truax Flex Series grass seed drill, or approved equal 2.4. seed half of the seed mix in one direction. then, make second pass with the remaining half of the seed mix in a direction perpendicular to the first direction using the Truax seeder, separate culti-packing or rolling not required because the Truax has built-in culti-packer 2.5. chest mounted Truax Seed Slinger -- a broadcast seeder for warm season grasses on small areas. Note separate small hopper for forb seeds Cool season Grasses and Forbs 3.1. larger, heavier cool season grass (CSG) seed mix requires different spreader than for WSGs 3.2. use broadcast seeder in passes, the second perpendicular to the first 3.3. depending on the machinery used, forb mix may be seeded separately, again in passes 3.4. CSG seeding requires incorporation into the top 1/8” to 1/4” of seedbed, so, use chain-link fence drag mat, or approved equa Straw Mulching 4.1. immediately after seeding and packing (WSG) or drag matting (CSG), mulch entire meadow area with chopped small-grain straw (wheat, oats, or rye) 4.2. straw must be clean and free weed seeds 4.3. hay shall specifically forbidden because often contains weed seeds, and even viable seeds from the hay grass itself 4.4. apply straw mulch at a rate of 90-100 lbs. per 1,000 square feet keep soil moist, protect young seedlings, and limit soil erosion, use Finn Straw Blower B70, or approved equal, machine chops and blows in one operation Soil Moisture Monitoring and Watering 5.1. Soil shall probed with soil moisture meter twice weekly during the first 6 weeks after seeding (the germination period), nsure moisture from the seedbed surface to just below the active root zone. 5.2. When soil is too dry, irrigation shall

event 1.2. During Years 2 and 3,

the

to

the meadows monthly during the growing season 1.3. Require the Contractor to submit inspection reports the Project LA within 3 working days after the site inspection 1.4. While sprouting is occurring, irrigate sufficiently to keep soil consistently damp to just below the rooting zone 1.5. Monitor soil moisture using soil moisture meter twice weekly 1.6. During Year 1, normal rainfall is not adequate once most seeds have sprouted, water twice weekly; allow brief drying of soil surface between waterings 1.7. During sunny days, any required watering shall be done between a.m. and 10 a.m.; when overcast, any time during daylight hours is acceptable 1.8. Water seeded areas at controlled rates that are less than the rate at which the soil can absorb water to prevent runoff 1.9. During Years 2 and 3, irrigate only during drought periods; when necessary, irrigate deeply (to below the root zone) once or twice per week Prairie meadow, Year 1-4 2.1. in Year 2, use high rotary mower in mid-June to cut all growth to 10”-12” 2.2. For any aggressive weeds that reappear after the mid-June cut, use a power string trimmer, or spot spray or hand pull, as directed by the Project LA 2.3. Never allow unwanted weeds to set and disperse their seeds 2.4. During Year 3, in mid-Spring, scalp mow with rotary mower to approx. 1” above soil surface. 2.5. Immediately rake; remove mower trimmings to campus compost facility 2.6. require reseeding of bare patches larger than sq. feet 2.7. Call on Contractor monitor the Prairie Meadow one time in late May and one time in July for soil conditions, seeded species diversity, possible weed infestation, and any other emerging issues such as extensive herbivory. 2.8.Contractor’s report shall be submitted to Project LA within days, complete with recommended actions. 2.9. Since the Prairie Meadow was scalp-mowed (or burned) during Year 3, unlikely that this will be needed again in Year 4. Mesic and rain Meadow, Years 1-3 3.1. unless there’s a severe infestation of annual weeds, mowing is not required in year 3.2. Where weed infestation does occur, cut back to 6” height (“bootstrap height”) before any weeds have set seed, using high rota mower 3.3. Rotary mowing to height of approx. 6”-8” shall take place in early Fall in Year 3.4. rake and remove cut plant residue prior to freeze-up; deliver residue OPP compost facilities 3.5. Mesic and Rain Meadows may require fertilizer inputs in Years and/or 3.6. instruct the Contractor to obtain soil tests May of both Years and 3; when obtained, the results shall be submitted to the Project LA within days 3.7. Project LA must approve lab recommendations prior Contractor applying any fertilizer Managing weeds: 4.1. for noxious, persistent weeds, hand pulling or spot spray with herbicide approved by the Office of Physical Plant during non windy conditions only 4.2. require Contractor to submit proof of PA Pesticide Application Certification to you (the LA) prior to applying any herbicide on site Herbivory Control 5.1. the meadow will quickly become habitat, so expect some herbivory by rabbits, groundhogs, meadow voles, mice and moles 5.2. require Contractor to monitor and report to LA within days after his/her visit 5.3. include a measure (timing, extent of damage) that enacts herbivory control, and specifies how to replace damaged meadow patches
