introduction
Disrupted and disconnected urban ecosystems (water, agriculture, flora and fauna) resulting from rapid urbanization have detrimental impacts on the health and wellbeing of urban citizens; particularly disadvantaged social groups. This studio developed an appreciation for design skills in landscape architecture within the city-scale context of Bangalore, one of the most rapidly urbanizing cities in India. Greater Bangalore is the administrative, cultural, commercial, industrial, and knowledge capital of the state of Karnataka. It is currently the fifth largest metropolis in India with a population of about 7 million, with a population density that increased from 10,732 to 13,392 persons per sq. km between 2001 and 2011. Rapid urbanization pushes urban infrastructure to its limits and often causes increased social inequity, but there is also increasing pressure on rural landscapes to supply the city with resources and food. This studio focused on designing productive urban landscapes—multifunctional landscapes that grow food in the city. The site selected for the design intervention was a typical, unplanned formal settlement in Hebbal district. A residential and mixeduse neighborhood, Hebbal supports a diverse population in terms of income, education, and religion. The physical environment lacks adequate waste treatment, which has severely polluted the channelized canal that runs through the center of the neighborhood. Students travelled to the site early February to conduct fieldwork. Through a community-engaged process, new design strategies were developed that integrate productive landscapes into the built, ecological and social urban systems with the aim of envisioning better work, live, and play environments. The students considered interdisciplinary requirements from planning guidelines, architecture design, engineering limitations; and developed an understanding of existing natural land and urban systems. Through the project site, they faced complex urban design issues in order to derive innovative design solutions using principles of ecology and sustainability.

Physical Conditions
Bangalore land use Bangalore, officially known as Bengaluru, is the capital of the Indian state of Karnataka. The city contains two urban settlements--City and Cantonment--which had developed as independent entities that merged into a single urban centre in 1949. Bangalore is also known as the “Silicon Valley of India” because of its role as the nation’s leading information technology (IT) exporter. Though highly developed, Bangalore is mostly filled with residential and agricultural land use. However, these agricultural plots are concentrated at the outskirt of the city while the residential zones are situated evenly around the city. The “Old Petta,” the historic heart of the city, constitutes an essential centre for wholesale and retail activities. The northeastern part of the city forms the second commercial hub in the Cantonment area. The southeastern zone is planned as the IT hub, with residential housing and large public and private software and IT enterprises. Developments situated at the northsouth axis are households for families who engage in trade and business. The series of maps provided serves as an analysis of how different zoning areas--from Bangalore to Hebbal-alter according to scale. The seggregation of zoning analysis gives an understanding of how Hebbal as a district functions and contributes to the larger city context. This allows for evaluation of planning rational and issues that influence existing site assets and constraints.
10
road and transportation condition The road network in Bangalore has a star-like structure where all the major roads converge on the centre of the city. The absence of transverse roads and lack of public transportation leads to severe congestion in the city’s core. Conflict: The relatively small addition of road space compared with the intensive spatial expansion of the city. There are 11 main markets in Bangalore and most of them are within 30 minutes driving distance under normal traffic flow.

District 7 land use Hebbal is located in District 7. The planning of District 7 has a relatively silimar percentage of residential, industrial, commercial, and transportation zones as compared to the zoning of Bangalore. However, there is a drastic increase in the percentage of public and semi-public development, with a steep drop in agricultural land use. This phenomenon signifies that District 7 is highly urbanised, serving as an essential political and institutional hub with little trace of rural activities. Hebbal is located in the southwestern zone of District 7, dedicated as a residential town and houses pharmaceutical and medical institutes. Furthermore, Hebbal flyover, the first highway that leads into Bangalore, influenced the development planning to cater to international corporations and automobile companies. Hebbal is also situated closely to Karnataka’s agricultural and poultry institutions that specialise in high-tech modified seeds, fisheries, and veterinary practices. Thus, with the high influx of educators, researchers, and business professionals, Hebbal is currently known as a residential stop for these professions.

TRAnsportation number of vehicles
Mode of transportation
Bus stops are concentrated along the highway on the west edge of Hebbal. There are only 7 bus stops within Hebbal district, making it isolated.
Hebbal has fewer, but more frequent routes from east to west, whereas it has more routes with less frequency from north to south. This indicates that the bus services do not meet demand.
bus stops
bus routes
Hebbal is located near the Hebbal Flyover, which serves as the main route linking the city to the airport. It is positioned as a gateway between the city and the rural surrounding areas. Traffic jams are a common condition. The number of vehicles in Bangalore has increased steadily and is more than 3.128 million (1 lakh = 100,000). The most common mode of transportation is bus and two-wheelers. There has been a considerable rise in the number of two-wheelers, which constitute about 71% of registered motor vehicles.

environmental pollution The pollution in Hebbal is mainly from domestic waste, not chemical pollution. There are five levels of pollution based on the size of the area. The pollution concentrates in certain locations with a high degree in and around the river. Pollution is also found along the secondary roads, with the least pollution found along the main roads; 30% of green spaces are polluted.
vehicles registered in bangalore
vehicular circulation Vehicular circulation is inefficient and has some problems: The main circulation route is incomplete and the secondary circulation is disconnected. There are many dead-end roads. These problems lead to high traffic congession, particularly at intersections between primary and secondary roads.
17
physical condition of zone 1 Zone 1 has an overall better physical condition than the other zones. However, it still has high contrasts in physical areas. One area might have a very good environmental condition: have tidy, clean, well-shaded streets with new buildings. Whereas, another area might have dense aging buildings, narrow roads, more trash and a polluted canal. Both areas have high and low income residents.

Food Types
Road width
Food sources are abundant, provided by cartwheel sellers, markets and eateries. These provide a wide range of foods catering to different dietary needs. However, they are situated mostly along the main roads, which affect traffic conditions by occupying the streetscape, pathways and conjunction points. There is a gap in food sources in the centre of this zone mainly due to poor road circulation, though a few cartwheel sellers transport their products through the alleys to increase their sales.
The road condition is related to the housing condition; the lower income areas tend to have narrower road width. Roads also tend to narrow closer to the canal. Road use and road dimensions are mismatched, resulting in conjestion.
Road width
Food density
This map shows the concentration of food types catering to different preferences (veg and non-veg); indicating variation in dietary needs. Areas with fewer fresh food markets have more restaruants. Although fresh fruits and vegetables are evenly distributed throughout the area, fresh meat is available only in one area (in the southwest portion of the map).
The road condition generally matches the community condition and road width. For narrow roads, the concrete pavement is usually not properly maintained. Some new roads are narrow but are paved in asphalt and so of better condition.

Ecology & Natural Environment
Water and Climate Macro Climate Many of today’s most pressing environmental problems—water and air pollution, biodiversity loss, invasive species spread, climate change— impact ecological systems at local to global scales. Understanding and addressing these problems thus requires perspectives that consider interactions between physical and biological processes at multiple spatial and temporal scales. Our team research in this area focuses on effects of human activities on ecosystem processes, native and exotic species distributions; maintaining habitat requirements and landscape connectivity for native species in human-dominated landscapes; influence of terrestrial
Water System ecosystems on water quality; and effects of multiple environmental India scale - Bangalore scale stressors (e.g., air pollution, climate change, fragmentation) on River basin of India ecosystem function. Our research in the areas of ecosystem and landscape ecology integrates approaches and tools would include field sampling, the use of GIS, relevant online sources, articles, agency reports and precedent projects. A primary objective of our research and investigation is to enhance the management of and provisioning of ecosystem services within a landscape & community based context.

Population, density and Growth
Population density, 2011
The population grew from 1.6 million in 1971 to 4.1 million in 1991, and 9.6 milliom in 2011. Over the past decase, the city’s population has grown more than 40%. In-migration accounts for the majority of the population growth. The primary driver is work opportunities. (Source: Census of India).
Age and Sex Distribution
Population, 2011
Population Distribution by Age and Sex in Bangalore, 2011 Ratio of females per 1,000 males (2011): Bangalore: 916; Hebbal: 954
Population Growth in Bangalore, 1981-2001 36
The skewed sex ratio is a small indicator of the inequality in nutritional access for women and young girls. It is also impacted by in-migration of men for work and societal preference for male children.
Literacy and Education
Bangalore is known for its high quality education and high literacy rate of 88%, as compared to the state average of 67%.
age distribution (Bangalore), 2011
More than half the population in Bangalore is under the age of 30--and a quarter are in their 20s. This means Bangalore is a young city.
Poverty and Deprivation (2011) The per capita urban poverty line in Karnatake is INR 1,373. The 2011-2012 urban poverty rate was 21.9%. Affordable and safe food is crucial for people to survive on limited incomes.

Food intake & Hunger Global hunger Index
religious eating habbits
According to the Global Hunger Index released by the International Food Policy Research Institute, India’s hunger index ranks 15th in the world. The Global Hunger Index calculates hunger levels based on three factors: the number of malnurished people in the country, the proportion of underweight children, and child mortality.
Hindus do not eat beef. Muslims and high caste Hindus do not eat pork. Indian beef is cheaper than lamb, which tends to be the most expensive meat. Devout Hindus and Buddhists are vegetarians. Jains are very strict vegetarians; they do not eat eggs, but do drink milk and eat butter. About half of the Indian population is vegetarian.

Looking back to the bangalore's history, the British influence is apparent in Bangalore's city scape. The geometric radial street patten reflects the typical characteristic of England garden. Religion plays a prominant role in India’s culture context, and also contributes to the current unique urban pattern: The temple or the garden will locate in the center of the district, and the road will be spread out in radial pattern, and usully park and temple are combined with each other. As a result, the temples which are the symbol of religion become part of street scape that people can see it from all the district.

Urban agriculture preference by age and religion This figure shows that people from different age groups that practice different religions have different preferences for urban agriculture. We found that Hindus had more of a preference for agricultural work, while Muslims had more of a preference for farm-grow for family or farmgrow to sell. Older respondents also prefered farmgrow for family or farm-grow to sell.

driveability & walkability Driveability is a measure of trasit accessibility, calculated as the distrance to the closest stop on each route, analyzing route frequency and type. Walkability is a measure of walking routes to destinations such as grocery stores, schools, parks, restaurants and retail. Research done by the Clean Air Initiative in Asia shows that Bangalore is among the top 4 cities where roads and pavements are not fit for pedestrians. Bangalore ranks second among 15 Asian cities on the Walkability Index, scoring poorly at 46/100.

Community Survey In total, 114 questionnaires were completed across the six zones. Results were that people usually shop for food 1-3 times per day. Most people do not have their own garden or any potted plants. Half of participants prefer to go to natural places on hot days. And the preferred way to grow food in the city was in a community garden. Although there were some common issues, there were differences among the six zones. In Zone 1, the most common issue voiced was about the drinking water shortage and air pollution. In Zone 3, the most common concern was lack of open space and issues with drinking water. In Zone 4, the biggest concern was the accummulation of trash (this zone was adjacent to the canal, where trash concentrated).

A Framework for a Resilient Hebbal
Self-Sufficiency Analysis
Rapid Growth
The growing population in Banglore as a city that provides a better prospect of life is putting pressure on the rural area. The increasing amount of food to feed the increasing population demands for a greater area of land for food productions.
Food Wastage Banglore is one of the biggest food producer for the world but according to a study by Food and Agriculture Organisation (FAO), they are currently not producing enough for their own citizens, making them vulnerable in terms of self-sufficiency.
Consumption Analysis Producing food for 9,641 residents living in 59.3 acres, equivalent of Hebbal requiring a land of 70 times more which spreads out to a 21.5 mile radius.
Household Income Analysis The rapid population growth is expected to increase significantly in the coming years as the city provides more job opportunities. This effectively impacts the rural area with the increase demand of food and land for production. The far distance between the food production and consumers further enhance the vulnerability of food security for the fellow residents. In order to aim towards a self-reliant city in Hebbal, we need be innovative in stitching productive landscapes in this built environment. The project propose to provide a framework that connects the rural and urban land while integrating existing programs with productive landscape in order to achieve a sustainable food production and consumption for the future.

The goal is to maximise the yields and quality of the crops produced. The selection of plants is based on several factors including popular consumption, high market value as well as the capability to grow in the different urban agricultural method such as hydroponics. The food shed map shows area where there are food concentration. Hebbal currently has a good food network along the perimeters of the site. It was noted that the food cart sellers have routes that they took while roving around the site.

Methodology
traffic jam air polution food wastage WHOLESALE MARKET
Based on the selected vegetables, their yield in pounds per 10ft of a row and the distance between row for vegetables to grow in Banglore, the average yield per 100 square feet of the vegetables is calculated. With the conversion of 1 pound equivalent to 16 ounces, which is approximately 2 cups, the average of 968 cups per100 square feet is calculated. There are 43,560 square feet in one acre, therefore it is possible that in each acre for vegetable farming would potentially produce 421660.8 cups each year. If each person in Hebbal consumes the daily recommended 3 cups of vegetables by Indian Council of Medical Research, it is calculated each person needs 1095 cups in a year. If each person needs 0.44 acres to sustain a 2300 calories diet, it is calculated that in order to reach 100% self-sufficieny in Hebbal, a total of 4242.04 acres is needed.
The current food system sees an extensive food mile in Hebbal. Most of their grocerries are bought from food cart sellers or stores that purchased their goods from a distant bigger wholesale market. The foods are exposed to air polution, especially during massive traffic jam Banglore is known for. This affects the quality of food the residents of Hebbal consume.
Based on the calculation the areas that are provided for production are recorded based on the number of cups produced in an acre. 67
food for hebbal Vision
1. Increase land dedicated to food production through a continuous productive landscape 2. Promote community health and engagement 3. Increase food access to high-quality food to residents in all communities 4. Strengthen community identity
Strategies
The strategies focuses in 4 phases. The first phase cleans up the existing physical condition of the vacant lands. The second phase introduces the studio’s efforts in productive landscape of their chosen sites. The third phase transforms all the exsiting vacant land into the different productive landscape, according to the spatial matrix. The last phase bridges out towards the rural landscape and tapping onto vacant lands out of Hebbal.
PHASE 2 PHASE 3 STREET GREENING
68
Spatial Matrix
Upon laying over Banglore Masterplan 2015, the areas are selected based on several consideration such as their current function, if it is vacant, and its location by the lake that connects from Hebbal to Kalkere Lake. In Phase 4, Hebbal will be able to achieve 80% self sufficiency before the next available land that has agricultural activities happening existingly.

he(r)bbal pockets Empowering Rural People for Primary Healthcare
Objectives Current Situation The delivery of basic needs such as healthcare services are still developing in small scale despite there being an emphasis on healthcare provision in Hebbal. Similar to developed regions in Bangalore, healthcare services are important and the lack of affordable healthcare resources and medical services among the residents in Hebbal is still an ongoing issue. The current air and water pollution in Hebbal cause health hazards and lead to many residents developing early onset of respiratory problems, dermatological-related problems and other common allergies issues.
To develop - Adopting medicinal To advance - Collaborating with
herbs as a starting point to promote the importance of health, it is also an opportunity for productive landscape in Hebbal.
To empower - Engaging senior
citizens who had the experience in farming and introducing women to the workforce and contribute to the operation of this sustainable herbs project.

Proximity Analysis
The goal of Ayurvedic medicine is to help people live long, healthy and balanced lives without the need for prescription drugs, complicated surgeries or suffering of painful conditions. This traditional approach has been practised by Hebbal locals for many years, relying on home-grown medicinal herbs to prevent minor ailments. 84
building & site Analysis
future vision Acknowledging the importance of medicinal herbs is crucial in providing access to affordable medication for Hebbal residents. Residents believe strongly in Ayurveda, a medicine system with historical roots, and it is currently an alternative medicine being used in some illnesses with modern medicine. As the knowledge of traditional medicine has its worth in recuperation and healing, there is a possibility to expand this to tackle some of the harder to deal with diseases, such as their top illnesses - lung cancer and respiratory related diseases.

Community Engagement
The existing site holds 3 residential houses with potential spaces to transform it into a productive landscape. Located right beside educational insitutions, it provides a perfect platform for agriculture research and development for students and the communities in exchange and transfer of knowledge and ideas. VACANT LAND 2
Existing Conditions The empty polluted lands in Hebbal are considered “dying,” or even “dead,” due to improper waste disposal which has been affecting health problems and a spread of diseases in the district. It is crucial to tackle healthcare in the community because private health care is expensive, often unregulated and variable in quality. Besides being unreliable for the illiterate, it is also unaffordable by low income communities. To control the spread of diseases and reduce the growing rates of mortality due to lack of adequate health facilities, special attention needs to be given to health care in Hebbal. The selected site lies near Acharya Institute of Health Sciences. With two vacant and five potential land areas that appear suitable for an agriculture system intervention to serves for consumption and medicinal value to the community.

Crop Selection | Water System | Programs Crop Selection: Selective and companion planting are being implemented to improve the nutritional value of specific vegetables and herbs. Very delicate placement of plants (especially vegetables and herbs) will gain mutual benefit enhancing the quality and efficency of crops growth Water System: With the site located at low point, we could channel rainwater from existing commercial and residential rooftops onto the site and into the water tank for storage and supply. Programs: The agricultural spaces welcomes the community and students to come together for exchange of farming knowledge and to apply what they have learned in these spaces. Getting the community more invovled would increase the sense of ownership where residents are aware that these spaces are valuable to them

HABITAT 22 Design for 22% of the residents living in infromal settlments in Bangalore
URBANIZATION OF BANGALORE Rapid development of IT industry, biotechnology and educational institutions [6] created enormous opportunities for employments and massive influx of migrants seeking better livelihoods. The urban space has sprawled rapidly from 69 km2 in 1949 to 741 km2 in 2007 [10]. Overwhelming urbanization also resulted in insufficiency of public housing, transportation system, basic infrastructure, and compromised environmental qualities. The is city struggling to keep up with the drastically increasing needs from the demographic and economic booms.
Project Statement During the rapid urbanization of Bangalore in the passed decades, the lack of plannning and investment in the development of public infrastructure, housing and transportation system, health and education services also resulted in social issues. One key issue is the consistently increasing urban informal habtitants, socioeconomic disparities and resulted in marginalization of the disadvantaged groups (inclusively native villages engulfed by urbanization, poor immigrants coming in search for employment [11]) These informal settlments are always established under compromised conditions of hazards of environmental pollutions, no or few sanitation facilities, and insecured food supply. The objective of this design is to address the key factors of informal settlement - “Informality, Scarcity, Temporality”, and to create a system to enable the informal dwellers to better utilize the limited resource, tackle the challenges and resolve some social and livelihood issue. Leveraging on the ecosystem service of productive landscape to extend the opportunities for the urban poor.
Figure: Land Use of Bangalore
CONDITIONS OF INFORMAL SETTLEMENT Besides low structural quality and insecure tenure, informal settlements’ lack of basic infrastructure (water and sanitation), location near pollution sources, malnutrition and health risk are all severe issues for the informal dwellers.

VEGETATION IN BANGALORE’S SLUMS
HOW ABOUT THE PEOPLE?
Ecosystem Services also have unique and important value for the urban poor. In a research conducted in 44 slums in Bangalore cities, the findings indicate enthusiam among informal settlers for growing various types of vegetation, particulary in the cultural and religious context of India.
The unprecedented urban expansion and population growth had resulted in fundamental Tribulations of informal dwellers changes in the dynamics structuring urban space. The social disparity and marginalization of the foreign and disadvantaged further brings difficulties for the poor to survive.

INFORMAL SETTLEMENT IN HEBBAL The chosen site of informal settlement in Hebbal represents many typical characters of this type of urban habitat. On one side, it is bordered by the main waterway flowing through Hebbal (which is severely polluted), on the other side, it is also near the main commercial road. There is a big waste collection and recyling area at the chosen site. Shops and Eateries

STRATEGY 2: GROWING FROM SCARCITY
STRATEGY 3: SUSTAINING TEMPORALITY
The three features as the central focal point are: Community Kitchen, Farming Workshop, and Wastewater Commercial Zone is designated to be the frontage of the informal settlement, including eateries, an open Garden (for grey water recycling). The adjacent Central Plaza is built on top of a water tank, for treated market and commercial nurseries for selling young plants, compost, and other farming productions for income. Besides edible crops, ornamental and religious plants would also be produced for sales. water and rain water storage. Water, most limiting and valuable resource, is the key factor to strategize growth from scarcity. The water treatment system is integrated into the landscape and community space, serving as green and blue infrastructure as a Low Cost Solution.

The proposal is not intended to come up with a solid design solution for informal settlement, but to strategize a system to enable the informal habitatants to better utilize limited resources, tackle challenges and resolve social and economic issues to a degree. Subsequently, it can improve resilience and engage them as contributors for social developments.
Transcendence
Social Boundaries
Project Overview Source : Revised Master Plan 2015, Bangalore Development Authority
Bangalore, is currently the third most populous megacity and the second fastest-growing major metropolis in India, housing numerous education and research institutes. With the high influx of immigrants mixed with existing locals, this amplifies tension regarding social stratification, contrasting community interest and religious beliefs. These phenomena have shaped individual ideologies to be rigid, exclusive, and inattentive to surrounding communal groups and their respective concerns. Thus, the lack of understanding and indulgence has led to complications within the complex relationship of physical, social and psychological realms in India. Transcendence is a community-centric design movement that builds social capital using landscape as a medium to go beyond physical, social and psychological boundaries from individuals to society level.

Canal Revitalizition
Creating new confluence of nature and society
Site Analysis
Channel width: 6-10m Channel height: 3m
The water problem is a serious issue in Hebbal district. People lack clean water for daily use and drink while the only one canal in Hebbal is polluted and covered by garbage. In addition, people in Hebbal do not have enough public space for them to do activities and children can only play on the street. The aim of this project is to transform the original canal into a vitality and vigorous public space for people to do activities with cleaner water.

Community survey Analysis
Strategy 1 At the macro scale, the polluted water will influence the larger water system in India. Therefore, controlling the pollution source and treating it close to the source is best. Water pollution sources on site: (1) 50% of sewage will be discharged into canal through drainage due to pipeline leakage (dry season) (2) People throw garbage into the canal (all seasons) (3) Garbage flows into the canal by rain (rainy season) The water problem is a serious issue in Hebbal district. People lack clean water for daily use and drink while the one canal in Hebbal is seriously polluted and covered by garbage, emitting a terrible odor.
Open the canal and clear up the garbage. Create transition zones to collect the polluted water and use constructed wetlands to purify it. Adding a water tank and widening the canal can reduce the water level 0.3 m during the rainy season.
Water storage capacity: 1000m3
Can treat polluted water in dry season Treated water can be used for irragation.
Strategy 2 Modify the canal edge and create a variety of spaces for people to use both in the monsoon and dry season.
In addition, many residents mentioned lack of public space. Children can only play in the streets. Adults can only hang out on the street or chat with others in front of the houses.
Strategy 3
Establish a new pedestrian walking system and create open space by using religious elements to improve connection across communities. Mosque: house of worship + front porch + cloister
This chart shows that drinking water shortage is the most important community issue. Water pollution and lack of public space ranked 5th and 6th, they are important issues as traffic jam and air pollution, which ranked 4th and 2nd, are mainly caused by poor infrastructures. The water pollution and garbage problem are issues that are mainly put forward by people in the zones which are nearest to the canal.
