Goa is a goldmine of biodiversity and native forests are the crucial negotiators that tie these ecosystems together. As awareness increases about habitat loss and deforestation, people have taken the responsibility of hosting planting and re-wilding drives. The first step in this process is to identify and select native plant species which are most effective and resource efficient for natural landscaping. Native trees offer huge short term and long term benefits:

• Native trees are well-adapted to the local climate, which means they will have the best chance at survival.

• Native trees prevent population decline of the local wildlife as the animals are not forced to shift into unfamiliar habitats.

• While non-native trees might not do well up against local pests, native trees often don’t have as many pest problems because they develop symbiotic relationships with other local species.

Here are 4 popular, easy to source, and easy to plant native species of Goa:

Terminalia Elliptica or The ‘Indian Laurel’ is the State tree of Goa. A few other names of this tree are Mati, Asna, Saj, or Crocodile Bark Tree.

Terminalia bellirica is a deciduous tree that grows upto 35 m in height. It is a sun loving tree that thrives in slightly moist soils. The fruit of the tree is often celebrated for its medicinal properties.

Pterocarpus marsupium, also known as Asann and Malabar kino is a deciduous tree that can grow up to 30 m (98 ft) tall. It is native to India, Nepal and Sri Lanka. The beautiful yellow flowered tree however is currently on the list of threatened species due to dwindling numbers and needs to be revived.

Holoptelea integrifolia, also called The Indian Elm is a deciduous tree that grows upto 25m in height. It is often sourced for timber which makes cheap furniture and also used as firewood in rural parts. Its flowers, leaves and bark have medicinal uses.

Apart from this Goa has several indigenous fruit trees including jack fruit, tamarind, guava, pineapple, and kokum. While these are not advisable for highways, they are wonderfully suited for smaller city avenues, parks, city campuses, and most importantly individual residential plots.

A detailed list of Goa’s native trees can be found in this directory. These trees support a lot of insects and creepy crawlies. This post tells you how you can design to coexist with and celebrate Goa’s biodiversity.

Goa is listed among the 36 most important biodiversity hotspots in the worls. To know more about the ecological significance of this belt, you can read our blogpost on Protecting the Western Ghats here.

In this session, we speak to Shubhendu Sharma, Founder of Afforestt. Afforestt does amazing work rewilding barren land in rural as well as urban areas, in different climatic zones, using different species through a process called the Miyawaki Method. Over the conversation, we discuss the fundamentals of the Miyawaki technique, the how tos of growing a forest, the benefits of picking native species, the ways and means of making forests and landscapes in the cities, as well as the challenges of growing and maintaining a dense forest. We also delve into the subject of mono-planting and understand how it impacts local biodiversity.

Here are some key takeaways from the session:

• Above ground, we perceive the forest as multiple trees, plants, and shrubs. But below ground, the forest grows as a single organism. ‘The Hidden Life of Trees’ by Peter Wohlleben is a great read to understand how trees grow and communicate

• ‘Jungle Trees of Central India’ by Pradip Krishen is an excellent resource to learn about Indian native trees.

• One can visit the following native forests in India to find clues about and study the local indigenous species:

  • Sanjay Gandhi National Park in Mumbai

  • Kabini Forest in Bangalore

  • Srisailam Reserve in Hyderabad

  • Annamalai Forest in Tamil Nadu

  • Ridge Forest of the Aravalli Range in Delhi

  • Alwar Forest in Gurgaon and Haryana

  • Kanha and Tadoba National Parks in Central India

  • Jhilli Milli Forest in Kolkata

  • Jhalana Forest in Jaipur

  • Bathinda Forest in Punjab

  • Nepli Forest in Chandigarh

• Afforestt also has an open source DIY toolkit on How To Build Forests. You can find the methodology here.

In this IG Live, I speak to Dr Pallavi Latkar, the technical brains behind the ecological site planning at our project, The House with Three Pavilions . Pallavi is an ecological expert, she is the Founder and Director at GRASSROOTS Research & Consultancy in Mumbai. Over the Live session, Pallavi and I discuss the extensive rain water harvesting system we have created at The House with Three Pavilions. For this site with many contours and topographical variations in Goa, this monsoon ready water management has been a great way of rainwater harvesting and distribution to recharge the underground water table. Over the course of our conversation, we get into the details behind the site planning and construction, discussing the key techniques we have employed. We also speak about the benefits of conserving natural water systems and debunk myths around the maintenance of these systems.

Here are some additional takeaways from the session:

• Every site has a story to tell - the story of its soil, water, and vegetation. Listen to the story - smell, see, touch and feel its elements.

• Our sights have many hidden clues in plain sight - within the trees, plants,and shrubbery. FOr example:

  • A Mango Tree with a dense canopy tells us the site has a good water table.

  • The presence of wild Colocassia indicates the spot where water will stand and collect in the monsoons.

  • Moringa and Neem Trees are native trees that are most beloved by birds.

  • ‘Shankasur’ or Cesalphinia is a favourite haven for bulbuls.

  • Fish-tail Palms will attract Barbets, Coppersmiths, and Hornbills.

• Young architects who do not have access to an environmental consultant can start off by using free and universal tools such as:.

  • Google Earth Imagery from which contour levels of the site can be approximately extracted. 

  • Toposheets of India can be found online - it may require some searching on websites of Landscape Universities worldwide. 

  • Rainfall data and history are available online at various sites including The Meteorological Department website to ascertain the precipitation on your site.

  • The website of The Irrigation Department of India which gives the specifics about soil in every region. 

  • Software like Google SketchUp, Revit and Grasshopper which allow you to geo-locate and model the site and surroundings in 3D which will help you visualize the terrain.  

I recently conducted an IG Live on taking A Site Positive Approach. As a follow up to that, I conducted another video session to get into details and answer pertinent questions about Rainwater Harvesting. I discuss the elements that make up a RWH system, compare the differences between rural and urban water management systems, and introduce some of the various options available for harvesting water. I also speak about the Goan monsoon patterns and the site specific methods that are useful in tropical areas. As an example, I explain the simple but effective well system created at Navovado, our completed vacation house in Goa. I also explore natural water systems such as ponds and bioswales which we have physically implemented at our project The House with Three Pavilions in Goa.

In this IG Live, I delve into the factors involved in taking A Site Positive Approach. I speak about how design can contribute to the land it stands on as well as simple measures that can be taken to ensure the site is preserved and that resources are managed well during and after construction. Over the Live, I explain the importance of the water management systems at our houses in Goa, and the natural systems we have implemented such as a pond and bioswales. I also answer questions about site positivity in the rural and urban contexts, speak about the opportunities offered by certain materials and the feasibility of creating a positive impact. Tune in to watch the entire session.

To know more about taking a site positive approach, you can read our blogpost on the subject which looks at the strategies implemented at The House With Three Pavilions.

How does one build in a rural location with the objective to have minimal or zero-impact on the environment?

This question is the primary driver behind the site planning strategy for The House with Three Pavilions located in Goa, India.

The project site is located on the edge of rice paddy fields with a dense cluster of local forest trees on one side and a coconut grove in the middle. The following diagram illustrates some of the critical measures taken as part of the site planning strategy.

WHY IS AN ECOLOGICAL RESPONSE ADOPTED?

• As Goa gentrifies, rampant new construction threatens to rock the delicate balance between nature and man. This project is our attempt to showcase that the built form can tread lightly on the land with conscious design and measured planning. 

• The design focus is to leave a minimal or zero-impact on the functioning natural ecological cycles at the site that pre-date the new construction. 

• The site is geographically located along the path of the watershed from surrounding higher elevations that finally drains into the Arabian Sea. The design planning is oriented to support and improve the water movement through a comprehensive water management plan.

• The water management plan is implemented to address three primary concerns around the site - to recharge the depleted underground water table, to increase water availability for the paddy fields bordering the site, and to reduce the water load on the Municipal Draining system.

WHAT HAS BEEN DONE?

• During the survey, a natural depression was found at the center of the site with a perennial wetland hosting diverse flora and fauna. This existing depression was dug out (until the underground water level in the driest month) and integrated with the existing well on the site. Today, this natural wetland feature is preserved and developed into a seasonal waterbody which also forms the focal point for the landscape created using a native planting strategy.

• All the roof rain water runoff is captured and along with the site surface runoff, it is directed into the central seasonal pond for rain water harvesting. The edges of the pond were formalized with mortar-less retaining walls built in local laterite rubble. This was done to reduce the erosion of the pond edges and to retain the water as a permanent feature in the landscape

• The pond was further connected to a newly planned system of bioswales that spread the collected runoff water over a larger site surface area increasing the rate and extent of percolation on the site. This keeps the level of our underground water table high throughout the year and the soil moist, reducing the garden irrigation requirement in the dry season.

• The bioswales use no cement in their construction and can absorb water through the walls and the base. The construction of the bioswales and the pond without cement, also allows for the water to remain clean without any toxicity of the cement leaching into the landscape.

HOW DOES THIS CREATE A POSITIVE IMPACT?

• The water management was a critical part of this project and offsets the load on the rudimentary public storm water systems found in the Goan villages especially during the heavy monsoons.

• As a result of our efforts, the underground water levels have been improved hence negating the impact of the house construction on the environment. We have been able to prevent any additional flooding at the neighboring fields or any other low-lying area in the village. 

• The project also prioritises the enhancement of the site’s resources and biodiversity. In doing so, it also creates a positive impact on its surroundings by protecting the agrarian viability which is constantly threatened by new construction and increased human activity. Our success can be measured by the number of birds, reptiles, butterflies and insects that can be found on the site today. We have uncovered peacock eggs, cuckoo eggs and baby parrots on our site. It is a win to see that the animals continue to find the site a safe space even as they come in close contact with the human life around, making this truly a space for all seasons and species.

South Goa is paradise on earth with its lush paddy fields, old Portuguese mansions, numerous forests and sanctuaries, pristine beaches and rivers, quaint churches and magnificent forts. The streets of South Goa speak to a different era with a distinctive old world charm. In the first part of this two part blog post, we have selected a few of the quintessential South Goan charms from a long list of abundant natural and man-made wonders.

Cabo de Rama

Cabo de Rama is a relic left from times bygone. Once a magnificent fort that housed an entire community, it remains one of the oldest and largest forts of South Goa and offers a fantastic view of the Canacona Beach below.

Chandor & Loutolim

The villages of Chandor and Loutolim give you the giddy feeling of opening an old book. The Portuguese style sweeps elegantly across the villagescape, evident in the beautiful old world architecture and the laid back lifestyle. Both villages are famous for their centuries old colonial mansions that stand tall even today. We will be looking at these beautiful palatial homes in Part II of our blog post.

Netravali Lake

The Netravali Bubbling Lake in the Sanguem district is one of the lesser known beauties of South Goa. This one of a kind natural lake is known for its mysterious and continuous bubbling water surface throughout the year.

Galgibaga

The Galgibaga Beach is home to silver sands, endless rows of coconut trees and the charming Olive Ridley turtles which come onto the shores every year between November and February to nest and hatch. A ferry ride crossing the picturesque Galgibaga river is the best way to get to the beach.

Naval Aviation Museum

Established in 1947, Naval Aviation Museum offers a glimpse into military history. The museum is designed to look like the interior of a naval aircraft carrier with galleries displaying naval equipment and prominent battles, including a simulation room. It also has an outdoor aircraft park with an exhibition of old aircrafts and engines.The museum is set on a plateau and overlooks the scenic Bogmalo beach.

Mollem National Park

The Mollem National Park is set in a humble 240 sqkm belt nestled in the Western Ghats and houses a wide array of tropical flora and fauna with over 200 unique Indian species. Recognised as one of 36 most crucial biodiversity hotspots in the world, the sanctuary is now threatened by 3 infrastructure projects, announced by the state government. The alarming proposal resulted in widespread dissent with thousands of people coming together for the ‘Save Mollem’ campaign.

Goa Map by Sarah Martin

Goa brings to mind images of earthly paradise with its golden coast, tropical greenery, a kaleidoscope like cityscape, and endless cultural experiences of various kinds. The idea of tourism in this state started off with local villagers opening their homes and kitchens, offering to show visitors around.

Goa officially became a state in May 1987. For easy management, it was then divided into two districts - North Goa and South Goa with Panjim and Margao as their respective headquarters. While both North Goa and South Goa embody the unique Goan ‘Sussegado’ spirit and have a plethora of options to choose from, there are some key differences in what they have to offer.

In a nutshell, North Goa has been the main magnet for tourists in the state. That has its positives, as North Goa now offers an amazing range of wonderful restaurants, bars, clubs and shopping boutiques. But some have begun to view North Goa as being a little ‘too-crowded’ and commercial with frequent traffic jams. South Goa on the contrary has retained its slow old Goa vibe. The beaches in South Goa are uncluttered and mostly occupied by high-end starred hotels that maintain them in relative pristine glory. South Goa is dotted with old Portuguese mansions and has fewer new concrete apartment buildings that dot North Goa. South Goa is known for its hidden gems such as the Cabo de Rama fort, Agonda beach and the Olive Ridley hatching sites at Galgibag beach.

A Comparison of North Goa vs. South Goa

South Goa

The beaches of South Goa on the other hand are quieter with a close connection to nature. Palolem beach, Colva beach, Butterfly beach and Benaulim beach are well known for their scenic views and the pristine surroundings.

Exploring South Goa is largely oriented around experiences in nature with places like Cabo De Gama, Rivona caves, the Rachol Fort as well as its own share of bird and wildlife sanctuaries.

The houses in South Goa speak to a different era and have a certain old world charm. The areas close to Chandor and Loutolim are known for their lavish colonial bungalows built many years ago by the Portuguese nobility. The buildings here are spaced out and far apart, with a focus on stepping out into the quiet of nature undisturbed.

In South Goa, the buzz and activity of a streetside market is found in the town of Margao, in the markets of Colem, Palolem and Caculo as well as along parts of the Colva beach. The town of Arossim in South Goa offers some of the best Goan cuisine and is known for its occasional vintage furniture markets.

The Codigo and Mollem Wildlife Sanctuaries are known for their bird-rich forest and varied flora. Several nesting sites of Olive Ridley marine turtles are also to be found in the region including Galjibag in the far south.

North Goa

Beaches

The beaches of North Goa are generally favoured by short term tourists and water sport enthusiasts.

places of interest

North Goa is home to many captivating churches, the world heritage churches at old Goa, famous forts such as Fort Aguada and Chapora Fort, the Latin Quarter in Panjim, as well as gorgeous wildlife parks and stretches for dolphin spotting.

Cityscape

North Goa is a hub of activity and urban density but it also houses beautiful Portuguese settlements and numerous quaint Portuguese churches that have stood strong for centuries. The Portuguese influence is evident in areas like Fontainhas in Panjim with narrow lanes and bright colors.

Local Markets

North Goa brims with colourful flea markets that sell everything from clothes and accessories to souvenirs, handicrafts, pottery and local products at very low prices. The Saturday Night Market in Arpora, the Anjuna Market on Wednesday, and the Mapusa Market on Friday are visited by both tourists and visitors.

Wildlife

The Salim Ali Sanctuary, near Old Goa, is heaven for ornithologists. Mhadei Wildlife Sanctuary and Bondla Wildlife Sanctuary are famous reserves in North Goa

Jodhpur is a beautiful city, with a majestic fort, luxury hotels, incredible shopping and even a zipline for the adrenaline junky. To add to it all, I found another visionary piece of the city quietly tucked away in the hills below the Mehrangarh Fort.

Rao Jodha Park, is a one of its kind, concerted effort in India to restore the natural ecology of a place. The large, rocky wasteland (now the park) had been taken over by Baavlia, a foreign invasive shrub from Central America.

Baavlia, a fast spreading plant (some consider it a weed) was introduced in Jodhpur over a century ago. It was originally thought that this magic plant would provide abundant grazing for the cattle in the city. The result however was that, it killed all the native plants in the area, and the animals refused to feed on it.

In 2006, identifying this as a problem with long term environmental damage, the Maharajas of Jodhpur initiated a project to restore the area to its original ecosystem. I was told that eradicating the Baavlia, sourcing seeds of original native species and allowing them to thrive once again was an arduous task. But the result is beautiful, it is a piece of historic Thar desert landscape, that is dry, rocky, with surprising bursts of color and water!

I am a huge optimist and any small measure of thoughtful action makes me happy and brings me joy. So I loved being in the park, listening to the stories, learning about the desert landscape by exploring, taking in the sights and smells. It is a great place to wander and wonder about the complexity of nature, its delicate balance and yet the resilience and longevity of it.

Why are native plants important ? Native plants are the species of plants that have adapted to the geographical and climatic conditions of a particular place. They are a vital part of the local food chain and natural ecosystem that has balanced itself over many years. They do not require additional irrigation, fertilizers, or other resources to grow. Once taken root they form a part of the ecosystem and can peacefully co-exist with other varieties of local flora and fauna. Finally, many traditional practices and livelihoods in the local area may also depend of the local species, such as traditional medicine, fodder for cattle, shelter, crafts, etc.
