AMANDA SILVANA COEN UNIVERSITY OF VIRGINIA, MLA 2016

PORTFOLIO IS A REFLECTION OF ONGOING WORK THAT EVOLVES FROM EXPERIENCES, BACKGROUND AND LANDSCAPES ENCOUNTERED THROUGHOUT LIFE. I constantly observe design in the world around me. Whether in a remote setting or in the middle of a bustling city, consciously or unconsciously, I collect, capture and digest what I see. Sometimes my reactions are expressed in writing.

Sometimes in images and drawings. And other times, in built objects.

I love to create, to tell stories and to connect with others through design. My work has taken on a variety of forms over the years and I have been greatly influenced by my travels. Each place has left its imprint on me, and I also like to think that I have left my own small mark as well.

II. GROUNDWORKS STUDIO | INSTRUCTOR: BRIAN OSBORN | CHARLOTTESVILLE, VA | FALL 2013 Each student was assigned a different landform to study closely throughout the semester. I focused on lake typologies to understand their life cycle, how they function and where they occur. This knowledge was then translated into a site design for public baths in Charlottesville, Virginia that would provide a gathering space and also help filter urban runoff before it re-entered the Rivanna watershed.

URBAN SECTION PERSPECTIVE Rhino, Illustrator, Photoshop A series of floating islands provide new grounds for habitation. The islands help filter water while also dynamically responding to sea level rise. As plant communities grow and merge, the islands increase in size, conglomerating, fusing and tethering as weather patterns and environmental conditions dictate.

PLANT RESOURCE ALLOCATION

Carbon produced in leaves via photosynthesis

Carbon distributed downwards to other non-photosynthetic tissues via phloem

H20 and ions transported to rest of plant via xylem

H20 and ions (N + P) taken up by roots from soil

CO2 N P Enzymes Microbes and fungi

Carbon, hydrogen and oxygen make up walls of plant cells. Together they create: Hemicellulose- Softest Cellulose- Sturdier Lignin- Toughest

Root growth favored over shoot growth when nutrient supply (N + P) is low.

DIAGRAM Rhino, Illustrator, Hand Drawing Plants allocate resources in ways that make most sense to their physical structure and the availability of nutrients and sunlight.

Resource allocation also determines the palatability of their biomass to decomposers which affects the rate of material breakdown.

Shoot growth favored over root growth when carbon supply is low.

Cellulose is composed of glucose rings attached to one another. Lignen is the glue that attaches cellulose and hemicellulose.

Microbes and fungi release enzymes to break down plant material and release nutrients in process.

N + P are released back into the soil as plant matter decomposes. Detached glucose ring can be taken up as food. Decomposer uses sugar for growth and releases CO2 as waste.

High N content in foliage increases the rate of photosynthesis leading to a faster growth rate, shorter leaf life span and more rapid rate of decomposition in litter.

Material layers provide the ingredients that drive ROTOLOGY, creating blankets that insulate the ground. In cooler months, the layers help retain heat captured throughout the summer.

In warmer months, they help cool the ground beneath. Their impact depends on materiality and timing- when the blanket is laid, its wear and tear and when it is removed- affecting growth cycles which constantly replenish the ingredients necessary for a choreographed weaving of site.

Sensors provide constant feedback of ground conditions that inform management decisions and measure change.

SECTION AXONS Rhino, Grasshopper, Illustrator Scenarios provide the opportunity for testing ideas. In this case, a herbaceous field is dominated by a few species, providing a monotonous surface with little variation in resource consumption methods. Needles gathered from surrounding coniferous forest are added to the field to introduce new nutrients and microbes to the ground, allowing species with different resource uptake mechanisms to become established. Over time, new plant growth will shade the ground, slowing lignin breakdown in needles immediately surrounding plants and changing the ecological system once again.

RULE CONDITIONAL PARAMETERS

An irrigation system is established where the number and arrangement of spray heads creates overlaps in moisture regimes that result in varying conditions. By selecting a plant palette with species that present a height gradient that directly relates to hydric conditions, a systems of vegetative “walls� can be created.

If there are more evenly spaced spray heads, there will be a more universal distribution of water. By spacing spray heads unevenly and establishing a non-central axis of rotation, ground conditions become more varied, allowing for increased ecological diversity.

TEXTILE CULTURES Photography | Collective Design

Project carried out in 2012 over four month period in collaboration with Awamaki, a textile cooperative in Ollantaytambo, Peru. Research forms part of long-term interest in cultural relationships to natural resources and the confluence with localized design.

BACKGROUND In 1969, Ghana received 14 Paper Mulberry plants from China to evaluate the potential for developing a paper industry. The project was abandoned and the plants were left unattended. Because both male and female species were introduced, it quickly became invasive and posed a new challenge to farmers who constantly battled to keep it at bay. More than 40 years later, the species now covers around 80,000 sq km of land and spreads rampantly in roadside gaps, abandoned fields and large forest gaps.

LANDSCAPES OF PAPERMAKING Site Interpretation | Mapping | Cultural Communications

Project initiated in summer 2014 through a grant from the UVA Center for Global Health to investigate the confluence of artisan cultures, natural resource use and global migration. It follows the history of the spread of the invasive Broussonetia papyrifera (Paper Mulberry) and examines how an environmental challenge was turned into an opportunity through an ongoing papermaking project in Kumasi, Ghana. Project emphasizes the importance of balancing human and ecological concerns when approaching global health.

How can discourse be shifted so that invasive species are understood in terms of FUNCTIONAL TRAITS regardless of geographic origin?

Prickly Pear

DIAGRAMS Rhino | Illustrator Invasive species offer an abundant source of constantly replenished biomass due to their rapid growth rate. To be considered invasive, a plant must arrive to a new environment, survive and thrive to the point that it offsets existing ecological dynamics (right). Functional traits provide a useful platform for shifting the conversation surrounding plants from one of geographic origin to one that focuses on the morphological, physiological and phenological characteristics that indirectly impact individual fitness through their effects on growth, reproduction and survival of the plant (below).

Roots can reach a depth of up to 10", developing at a rate of .5-2"/day.

Extensive energy is directed towards root development and development of first true leaves is relatively slow.

Squares (floral buds) form on the terminal of the plant with predictable fruiting pattern. The first fruiting branch is often produced at the sixth or seventh node on the main stem.

First white bloom appears and turns pink within 12 hours.

Vegetative growth continues.

First boll opens. Bolls maturing late in the season, when temperatures are lower, require a longer period for fiber growth and development and usually produce less lint of lower quality.

Leaves have fallen and plant is dormant. The boll and seeds are harvested and then separated to collect the fibers.

AGRICULTURAL SYSTEMS

Intensive

Extensive

Large input of labor and capital in relation to land area.

Often located close to market- lowers transportation costs.

Reliant on chemicals, pesticides and irrigation to drive high yields.

Small amount of labor and capital in relation to land being farmed.

Practiced where population densities are low and often far from primary markets.

Yields, often lower, depend on natural fertility of soil, terrain, climate and water availability.

Commonly found in hilly or mountainous regions.

Monitored, Targeted Small amount of labor and chemical inputs in relation to land area.

Practiced where ever misplaced gifts are found.

Yield depends on growth rate, climate specificities and surveillance techniques.
