THESIS QUESTION
“Do cities destroy other habitats and ecosystems? Of course. Do cities cause local extinctions of many species? Undoubtedly. We never built them as habitats for any species other than ourselves...Surely, if we build cities with intention, with niches full of unique resources, many other species will come on their own, and over time will adapt and evolve into unique urban creatures” Coral Reefs of the Land | Madhusudan Katti Article 11.4 Current Conservation 8 CITY AS AN ECOSYSTEM
How can architecture act as a catalyst for change or be an useful aid in spreading awareness for conservation? Nature has become a contained object which has been pushed away from cities. It is no more a part of the whole system. It exists as isolated pockets: lakes, parks, a green belt, a national park or even someone’s balcony. In order to experience nature, one has to visit these places. Urbanisation has led to missing links, missing data and lack of shared knowledge from one system to another. Small pockets of parks not connected to other parks lead to gene decay and even animal-human conflicts. This similarly gets mirrored in our cities as wella lack of communication within different systems. There is an urgent needs to realise the importance of the interdependant connections in ecosystems and allow more biodiversity to thrive in our cities. A close look at the ecological issues of India are also linked to marganilisation of traditional occupations, traditional knowledge and tribal communities. Traditional occupations have helped in maintaining an ecological balance resulting in a culturally protected ecosystem. The lands and forests were respected and maintained by the people. Government laws, and urbanisation have taken communities away from the ecosystem. Their land is taken over by government and they are restricted from visiting forests. This shift has led to ecological issues which also have many socio-economic implications. They can only be solved through community inclusive programs.
The culture of tribal communities like Bishnois, Banni, Maldharis, Santhals is closely linked to nature and they have lived sustainably for years. It is reflected in their food, agriculture practices and even in the houses they build. How do we revive this traditional knowledge?
THESIS QUESTION
Where does architecture play a role? How can architecture act as a catalyst for change or be an useful aid in spreading awareness for conservation? Look into ways to achieve co-existence between nature, built structures and the community. How can the building be a part of the ecosystem? Buildings tend to be thought of as static edificies that remain the same over the decades, interacting little with their environment. Can they be treated as more dynamic and interactive structures? Can a symbiotic relationship be achieved by a regenerative approach? The project will attempt to adopt regenerative architecture through the following principles: 1) Co-existence and Interdependence 2)Regeneration through whole system integration- the site, the systems, energy, the building, flora and fauna 3)Eliminate the concept of waste 4) Rely on natural forces 5) Co- Evolution of the whole system

01 BACKGROUND STUDY
GOA: BIODIVERSITY VERSES TOURISM HISTORY Goa was ruled by several dynasties of various origins from the 1st century BC to 1500 AD. During the rule of Kadambas, the name and fame of Goapuri had reached its zenith BRONZE & IRON AGE Sumerians had established trade contacts with Goa. Even before any king ruled the territory, a form of democracy existed in Goa- called the Gaunkari system.
GEOGRAPHY AND CLIMATE The state’s location between the Western Ghat mountains and the Arabian Sea midway on the west coast of India means it’s protected from extreme temperature fluctuations that commonly occur elsewhere in the country. Goa has a hot tropical climate with three main seasons (winter, summer, and monsoon). Heavy rainfall comes with the southwest monsoon winds causing rain in the state from June through September. Physical geography divides the state into three geographical divisions.These are mountainous Region formed by Sahyadri Ranges in the east, Plateau Region in the center and low-lying river basins and coastal plains. All the seven rivers of Goa originate from the Sahyadri range. Mandovi and Zuari drain the major portions of the plains. Having alluvial flats near the coastal regions, the river basins form rich agriculture tracts. The eastern hilly region has various endemic species of flora and fauna.The forests abound with the various species of birds common to the Konkan. 12 CITY AS AN ECOSYSTEM
COLONIALISM BY THE PORTUGUESE The Portuguese rule in Goa lasted for as long as 450 years. In 1510, when Goa was under Sultan Adil Shah of Bijapur, Portuguese attacked Goa under the command of Alfonso de Albuquerque.

CULTURE Once established in Ela, the Portuguese began a religious conquest, aiming to convert Hindus that had remained in the city. Goa reached its peak culturally and economically by the end of 16th century when it was fondly referred to as ‘Lisbon of the East’. Christianity arrived in Goa with St. Francis Xavier and the Jesuits. Muslim attacks weakened the Portuguese’s resistance. The Maratha Wars of 1664 to 1739 further destabilized the Portuguese stronghold in India.
Goa is a combination of Indian and Portuguese cultures, which together makes up a different ethnicity of the entire state. The Goans comprise of Christians, Catholics, Hindus and Muslims and they all celebrate their major festivals in harmony. The most popular celebrations are the Goa Carnival, Feast of John the Baptist, Ganesh Chaturthi, Diwali, Christmas, Easter, Shigmo. The largest festival in the state is the Feast of St. Francis Xavier.
INDEPENDENCE The liberation of Goa, known as Operation Vijay took place on December 17th, 1961. On December 19, 1961, Goa officially became part of India and two years later, held its first general election. FORMATION OF THE STATE Goa was declared as a Union Territory On May 31st, 1987 Goa has declared the 25th state of India.

Goa developed an international reputation in the 1960s as one of the prime stops on the legendary India-Nepal “hippie trail”. Many foreigners mostly from western Europe decided to create a community for Westerners here in Goa. It still remains today an international center of youth culture. Tourism is its primary industry, and is generally focused on the coastal areas of Goa, with decreased tourist activity inland. The case of Goa is more interesting given the conflict between Tourism and Biodiversity in Goa. It is famous for being a party capital with pristine beaches. The huge influx of tourist has led to lot of commercialization. Huge pressures are placed on the environment. This project looks at the other side of Goa. It explores how ecotourism can be used to support the environment and the locals of Goa.

KHAZANS: HISTORY & BIODIVERSITY FIRST SETTLERS The first documentation of khazans is in the sixth century AD, which is a donation of a khazan land by a king on a copper plate.
Mandovi

Khazans are coastal wetlands of Goa. They were reclaimed from mangrove forests, probably in the pre-Christian era by an intricate system of dykes, sluice gates and canals and put to multiple productive uses such as agriculture, aquaculture and salt panning.

GAUNKARI SYSTEM Khazan were traditionally owned by the community. These institutions were called gaunkaris (village-association), and had a few farmers managing the system. PORTUGUESE PERIOD Under the Portugese rule, these consortiums were renamed as comunidades. POST INDEPENDENCE The existing association of farmers prefer pisciculture (fish farming). In addition to the existing problems, the next generation has also not shown interest in agriculture with almost 90% of youngsters working in cities. The management of the Khazans became the reponsibility of the tenants’ association under the Agricultural Tenancy Act of 1964. CURRENT Khazan lands near the urban areas of Panjim, Mapusa, Margao, Calangute, Candolim were found to be under significant developmental pressure. Vast areas have been filled on the outskirts of Panjim.

Mangroves along the coast of Goa
Mangroves are salt-tolerant evergreen forests found along sheltered coastlines, estuaries, or rivers deltas in tropical and subtropical regions. Mangroves function as fish nurseries and nature’s defence systems. Communities depend on them as a source of wood and non-timber products (food, fodder, medicine and honey). In Goa, parts of mangroves have been used as indigenous medicine. They are rich in bioactive compounds, effective for treatment of diseases like fungal infections, kidney stone, rheumatism and malaria. Now, very few herbal practitioners can be found here. The role of mangroves in the marine food chain is crucial. The khazans also support the conservation of biological diversity by providing habitats, spawning grounds, nurseries and nutrients for a number of animals. This estuarian landscape is home to a variety of species of avifauna, fishes, shellfish, reptiles, otters and other mammals.

KHAZANS: CULTURE & HUMAN INTERACTIONS FEATURES OF KHAZANS
Dyanism of the Khazans with the changing seasons
Khazan is a self-operational system, utilizing tidal, hydro, and solar energy, and has functions that are highly complex but ecofriendly. Khazans have agricultural value with paddy fields. They are used for aquaculture, both as open-water estuarine mariculture (e.g. oysters and mussels) and as pond culture (mainly for shrimps). Salt pans can also be found here. Khazan lands have three main features: sluice gate, poim and two types of bunds.
Water Channel/ Poiem
Sluice Gate/ Manos
Dykes/ Bunds
Low Tide
High Tide
The communities have dieties related to the Khazans. ‘Manoseshwar’ is the diety of sluice gate or manos. Lord of Sea called ‘Sagareshwar’ at Betim .The temple showcases worship of marine fauna (reptiles, turtles, etc.)
Blessing of the crop during the harvest festival
16 C I T Y A S A N E CO SYST E M
The harvest festival is celebrated on the 5th day of the month of Bhadrapada (falls in August or September). Harvesting of new crops requires ceremonial blessings from the priest.
On the New Moon day of Pausha month (beginning of harvest season) the fishermen of Cambarjua island perform an age-old tradition- the crocodile worship or ‘Mangge Thapne”. The Cambarjua canal is home to Indian muggers. They make clay sculptures of crocodiles and worship them with flowers and other offerings so that the real crocodiles don’t hamper their fishing and farming activities. One can find a Holy Cross close to the sluice gates. Blessings from the priest are sought at the commencement of the fishing season in October or November. The boats are blessed and a prayer to lord Varuna (lord of water) is also perfomed. Many Catholic prrayers have retained past Hindu rituals. Jan
The Khazans are associated with many traditional oocupations throughut the year. Dec-Jan: Salt .field preparation Feb-Jul- Salt harvesting Jun-Oct-Paddy farming July-Dec- Fishing Nov- Jan- Vegetable farming

02 CASE STUDIES (PROGRAM)
CASE STUDIES: PROGRAMS THE NILGIRIS FIELD LEARNING CENTER The Nilgiri Biosphere Reserve (NBR) has for more than 25 years been the field learning centre for the Keystone Foundation, a voluntary agency based out of Kotagiri, More than 75% of the reserve is ‘protected area’ as a tiger reserve and national park. An estimated 30 distinct Adivasi groups are ancient residents of these forests and mountains. The reserve is spread over a 5500 sq km area and spans three states— Tamil Nadu, Karnataka and Kerala. The Nilgiris Field Learning Center has set up an integrative model of education, research and practice. Their stratergies aim to achieve conservation by promoting secure livelihoods that allow locals to shift away from unsustainable practices. Work is done mutually on environmental conservation and socioeconomic wellbeing of the community through radical collaborations.
The binaries structuring sustainable development: EDUCATION-RESEARCH-PRACTICE Blurring the boundaries between education, research and practice to link students, scientists and community members. SCIENCE-TRADITIONAL ECOLOGICAL KNOWLEDGE Integrate different knowledge systems for a holistic approach. CULTURAL DIVERSITY- BIODIVERSITY Promoting traditional livelihoods to protect the health of the ecosystem.
Cornell university based researchers, staff from Keystone Foundation and Adivasi sudents from the communities- participate in this bilingual programme of ‘structured cultural collisions’. The involvement of the Adivasi students has helped formed a patnership with twelve Adivasi groups. 20 C I T Y A S A N E C O S Y S T E M
TERI COASTAL HUB, VELHA GOA The Coastal Educational Hub funded by Nave Marg Foundation, covering an area of approximately 58,000 sq.m, is situated in the wetland area of Batim, Goa Velha, Goa.

WILD OTTERS RESEARCH CENTER, CHARAO ISLAND Researching the elusive animal’s behaviour and rehabilitating their population is Wild Otters Research, a conservation research centre that has a field base at the Charao Island, Goa. Wild Otters is an independent private company which was set up in 2018. Their volunteering Program is a multidisciplinary approach to conservation.
They also research about others mammals like bats, hyenas, civet,etc. and birds and even snakes around Goa. They conduct workshops and also have curated tours to mangroves, bird watching, etc. They also train college students and conduct sessions at schools to raise awareness among kids. They also work closely with the Forest Department. They conduct a cleanup every week with the Yoga Institute at the island.
22 C I T Y A S A N E C O S Y S T E M
Their base at Charao is an old Portuguese house.The Otter Collective is a call for artists around the world to create otter art and help stop the illegal otter pet trade in Southeast Asia. A merchandise shop is set up to generate some funds to support ongoing conservation work. They sell t-shirts, calendars, pens, etc. with these artworks.They also plan to open a café dedicated to the wildlife.
ILHA VERDE FARMER’S CLUB, ST. ESTEVAM ISLAND Goa has seen a decline in paddy cultivation in recent years because farmers and landowners have been reluctant to practice the conventional, labour-intensive method of raising nurseries and transplantation. In November 2015, when Father George Quadros deployed Japanese-made rice nursery and transplanting machines
experiment to their village’s fallow fields. They could recultivate 50 acres of the village’s barren land under the banner of the Illha Verde Farmers Club. Cameris and manai (traditional female and male tillers, respectively) from nearby mining affected villages were given employment. The government provided
on 3,000 sq. metres of paddy fields in Velsao village through an initiative of DBLS called Goa Paddy. Enthused by the success, Quadros convinced farmers in several villages in the vicinity to try out co-operative paddy cultivation. In 2018, threatened by plans for a coal transportation carriageway and the hunger for real estate development, the northern Goa island village of St. Estevem adapted the DBLS
subsidies throughout the farming process Real estate development seems to be on the rise and it is for this reason that the good villagers of St. Estavam have taken it upon themselves to revive farming and prevent the fields from being taken over. The locals have taken to farming these lands in the hope of preventing any gated communities or dumpyards from being built on them.

MANGROVE BROADWALK, PANJIM Under the Smart City Mission, the Imagine Panaji Smart City Development Ltd (IPSCDL) conceptualized and built the Mangrove Boardwalk. The making of this boardwalk didn’t require any deforestation. Located over the Ourem Creek, this one is spread across 1,100 square metres. It is located right behind the Goa State Central Library, this walk is an insight into the many types of mangrove species, the wildlife of the area and a call for a close interaction with nature. This boardwalk is actually in its first phase but there are plans to extend it even further where it will possibly touch the old Patto bridge.
It has been designed and planned by Goa based architect Gerardo de Cunha. The walkway is made of teak wood and the flooring rests on teak wood stilts which are buried 7m below the marshy soil under hydraulic pressure. The benches allow for those who just want to sit and enjoy the peace and quiet. There are boards with infographics that educates visitors about the importance of mangroves and the ecosystem that thrives around them.

SALT PANS, RIBANDER Solar salt production in Goa, described as a traditional village industry, has been practiced for the past 1,500 years by various communities. Since most of the rivers in Goa form estuaries and experience tidal influxes, salt production was started mainly in the coastal villages. Salt served as an important trade commodity too, playing an important role in the economy of Goa. With the Portuguese colonization of Goa in 1510, the salt production gained a huge momentum because of the increased demand for consumption. Five communities are involved in the salt production. They are Mithgaudas, Gauddos, Bhandaris, Agris and Agers.
Salt pans are feeding grounds for birds. Solar salterns are extreme environments that act as a niche for organisms which thrive over a range of extreme salinities, temperatures, pH, nutrient concentrations, oxygen availability, water activity and solar radiation. salt pans are excellent feeding grounds because of the availability of planktons.

The programs look into how cities as social-ecological systems can help to rebuild the lost networks. They highlight the importance of each stakeholder through binaries. These binaries will acclerate sustainable development and establish symbiosis between all the stakeholders. This will attempt to generate a dynamic self-organised system with a high level of heterogeneity. C I T Y A S A N E C O S Y S T E M 29

VANXIM
Chorão was a site of an ancient Tirtha “or sacred pool”. It was here that most of the nobility and rich resided, spending a life of comfort and luxury. This was the reason why Chorão Island became known as Ilha dos Fidalgos (Island of Noblemen).
One can reach here by taking a ferry from Divar. Paddy fields are forced stopped by eco-terrorist attack. Luxury hotel and Golf Course is sort to be forced upon this island but faced resistance from alert islanders and others.

BIODIVERSITY AROUND THE ISLANDS Salim Ali Bird Sanctuary is an estuarine mangrove habitat, which is declared as the bird sanctuary, and located on western tip of the Island of Chorão along the Mandovi River. About 105 species of fishes, 20 species of shellfishes and more than 225 species of crustaceans are found in esturian waters.

The wetlands are home to the smooth-coated otter (Lutrogale perspicillata), a species classified as ‘Vulnerable’ on the IUCN Red List. Many crocodiles watching boat trips are conducted regularly by different operators crocodiles. Manage Thapani is a form of crocodile worship. It takes place on new moon of Pausha month which is the beginning of threshing of harvest.
MBARJUA
ST. ESTEVAM
CAMBARJUA
St Estevam is known also known as Shakecho Juvo – the isle of vegetables – known for its long, seven-ridged, light green ladyfingers. In 2018, villagers decided to work together to recultivate 50 acres of the village’s barren land under the banner of the Illha Verde Farmers Club.
Mashel and Cumbharjua have long hosted the Sangodd, a water parade that features floats created by tying two boats to each other. These floats feature scenes from Hindu mythology. It is celebrated on the seventh day of Ganesh Chaturthi. The Cumbharjua canal is well known as a habitat of the Indian mugger crocodile.

CONTEXT: DIVAR ISLAND DIVAR ISLAND ‘Divaddi’
CULTURE
Divar Island is on the Mandovi River in North Goa. Salim Ali Bird Sanctuary, where you can see many species of birds and other animals, is at the edge of Divar. The island’s mangrove swamp is in fact, an extension of the sanctuary.
It is believed that the Island of Divar was once a site of Hindu pilgrimage- called Porne Tirth. The Church of Our Lady of Compassion (located in Piedade) is known to be the first Christian structure erected here in the earlt 1500s.
Well maintained, elegant Portuguese villas can be seen dotting the island. The village is as beautiful and serene as Goa can get. Initially, there were three Communidades in Divar : Piedade, São Matias (now Malar) and Narao. The Piedade Communidade is now sub-divided into two, Goltim and Navelim. Population: 5000 Main communities: Gowdas, Roman Catholics, Fisherman community A few people are also herbal practitioners (Parts of mangroves trees are used for making herbal medicine)
It is attended by thousands of tourists and locals. Each sectio Coloured floats and flags make for an
PEOPLE’S BIODIVERSITY REGISTER STATUS OF PBR IN INDIA The colours deepen with more number of PBRs
A PBR contains comprehensive information on availability and knowledge of local biological resources, their medicinal, other uses and any other traditional knowledge associated with them. Preparing PBRs is mandated under India’s Biological Diversity Act, 2002 and Rules, 2004. A young biologist, Hycintha Aguiar, is in charge of putting together a people’s biodiversity register (PBR) in consultation with the community. She is the chairperson of a local biodiversity management committee (BMC). 40 C I T Y A S A N E C O S Y S T E M

SITE FEATURES: NAVELIM The site is accessed from Ribandar through the ferry. The entry to the site is at the bend of the road. A mango tree on the edge of the site is the first stop of tourist trails. A dovornnem can be seen next to the tree. It is a structure that was used as a rest stop for fisherwomen to put goods (fish baskets) and provide shade. There are 360 degree views on all sides- hills and the Mandovi river. Buildings can be seen towards Ribandar side.The site slopes toward the creek. A man-made water body is used to store water for winters to cultivate vegetables. There is a football across the road. Some residents own orchards near the site.

ARCHITECTURE OF STILTS AND PAVILIONS Goa experiences a warm and humid climate. The design parameters for warm-humid climate are as follows: 1)Elongated plans for maximum ventilation 2)Blocks should be spread out with large open spaces in between to allow unrestricted air movement 3)Buildings on stilts promote ventilation 4)Double roof 5)Venetian blinds or louvers can be used 6)The openings should be shaded with extra overhangs (transitional spaces) 6)Sloped roofs 7) Materials which take time to heat up and reflect heat Keeping the sensitive landscape of the site in mind, the buildings are lifted up from the ground. The khazans function as soaking pits and the water is allowed to flow freely on the site.
Views- Redefine membranes
Stilts
Break the linearity of the site
Connection with the fields
The design follows the exisiting pathways on the site. The entrance is at the bend in the road, next to the famous tourist stopthe tree. The linear blocks branch out and form pockets of spaces for better interaction with the fields. The Maand is kept at the center and connects to transitional spaces of the different blocks. The Maand becomes an active core with many activities happening there over the day and over the year.

RECREATIONAL VALUE OF KHAZANS-MAAND Throughout Goa each village has Maand. A Maand is a space of about 100 sq. mts. for the cultural observances of the village, with perhaps a tree on it. It is a sacred place like a public square for communities to assemble for recreation, amusement or entertainment, performing arts, mainly singing and dancing, and other outdoor events. Festivals like Shigmo were celebrated.
Exhibition
Sadly, this multi-faceted tradition largely died out in the mid-90s. An attempt is made to revive the recreational value of Khazans.

LEARNING LABS The design allows field learning through the use of learning labs- pavilions with information kiosks, seating area near the fields and skywalks near the mangroves.
A holistic approach to learning. Whatever is learnt in classroooms can be experimentingon the field. Data collected from field visits can be analysed.

THE ROLE OF ART IN THE FIELD OF CONSERVATION
Art has been a useful tool for spreading awareness for environmental conservation. Through the medium of art, a larger group of people get to understand and appreciate the workings of nature. It is easier to communicate the issues as well. This role of art is explored in the project through the information galleries. The knowledge is shared as paintings, illustrations, graphics and comics.
