What are the lawscapes of Indigenous community forests?

9/25/2020

 
​~ by Prameek Kannan 

The paper explores the legal system of indigenous, forest dependent, tribal communities in Central India, and the multiple factors that influence its production. Forest dependent communities are not only an integral part of their ecosystems, but are a crucial ally for conservation initiatives as well. There have been few studies on the legal systems of indigenous tribes in India; this study looks to understand the same using a post-humanism approach. Posthumanism is a philosophy that considers humans in relation to ecology and technology, as opposed to in isolation, and therefore is an appropriate lens with which to view the environmental entities that influence tribal law in these communities. Here, the author looks to look at the role played by non-human entities in the production of the legal systems of these tribes.

​Two conservation priority landscapes in India - the Western Ghats and Central India remain major strongholds for several endemic and threatened species. However, urbanization and land conversion have resulted in wide-scale habitat fragmentation in both the landscapes. Fragmentation can alter how animals move across a landscape.

Wide-ranging mammals are particularly affected because they travel long distances to forage, breed, and find new territories. ​Identifying where and how have the mammalian movements been impacted at large regional scales will be critical in ensuring habitat connectivity and preventing local extinctions.

A new study published in Biological Conservation evaluated landscape-wide permeability to the movement of five endangered and vulnerable mammals - Asian Elephant, Gaur, Leopard, Sambar, and Sloth Bear in these two priority landscapes. The expansive study area covered 120,000 km2 of the Western Ghats and 729,000 km2 of the Central Indian region. For each of the five study species, the researchers modelled movement in the presence and absence of landscape features such as land-use land-cover, infrastructure and human population. They generated spatially explicit maps identifying areas where animal movement is impeded, reduced, unrestricted, increased, and channeled. These categories can be interpreted as follows – movement is impeded and reduced due to underlying high resistance landscape features, unrestricted due to underlying low resistance areas, finally increased and channeled due to high resistance surrounding landscape features.

Increased patchiness of forests as infrastructure construction rises in India

6/18/2020

 
~ by Kalyanee Paranjape

As one of the fastest growing economies in the world, India’s topography is undergoing rapid changes. Due to this expansion, ecosystems are under threat due to rapid land use changes and fragmentation. This has led to a growing interest in integrating conservation concerns in infrastructure development in India and an urgent need to illustrate the extent of their fragmentation.

A recent paper titled, “Bits and pieces: Forest fragmentation by linear intrusions in India”, aims to understand the impact of infrastructure developments on forest structural connectivity in India through analyzing forest patch characteristics. The authors have utilized patch size, amount of perforation and inter-patch distance to quantify clusters and fragmentation categories. Cluster analysis was used to identify large, intact patches that need to be preserved in future development action plans. And results were summarized at the national scale and for the existing protected area (PA) network. The results also cover two important conservation landscapes; the Western Ghats and Central India, which are rich in biodiversity and critical for survival of several threatened large mammals including tiger and Asian elephant.

The scientists found an increase in the number of forest patches and a reduction in the number of large patches due to linear infrastructure in India. High tension power-transmission lines and major roads were the most common linear intrusions within forests, and 70 % of the assessed protected areas had some amount of linear infrastructure passing through them. They also discovered that the highest fragmentation due to linear intrusions was observed in Central India, where an intact forest habitat of size 162,000 km2 was split into 5200 smaller patches with a mean patch size of 30 km2 and the largest patch being 16,850 km2 in size.

The authors recommend that infrastructure projects should not be established through the existing forests and when inevitable, proper mitigation strategies are vital to maintain connectivity. A more rational development plan would be to connect larger numbers of villages or people while safeguarding forests rather than to establish the shortest routes that would destroy forests, biodiversity, and ecosystem services. The study addresses the issue of fragmentation within forests and develops techniques that can be usefully applied to mitigate fragmentation problems in other fragile ecosystems such as tropical grasslands and savannas.

Vidya Venkatesh is a director at Last Wilderness Foundation and has a special interest in butterflies. She has also traveled various parts of India and shares a deep concern for conservation issues and contributes her services for the cause on every given opportunity. (Profile by NCCI coordinator Amrita Neelakantan)

What drew you to work with Last Wilderness Foundation (LWF) and when did you join?
After working for the corporate world for more than a decade, I took the leap and quit my job in 2010. I was in search of an opportunity which would allow me to work in the field of wildlife conservation. During the short stint of 1 year with Sanctuary Asia, one of my ex-bosses from Citigroup had recommended to meet Nikhil Nagle (Founder of LWF), who was also with Citigroup and had recently quit and started a Wildlife NGO. As one would say, I was just lucky to find my dream job! My passion for travel, wildlife & Bandhavgarh Tiger Reserve – it all came true! So the next thing I know is I’ve joined LWF in 2011

Over the last ten years of your work what have been some of the high points?
The best part of my work is that I’ve had extended families at every location that I’ve worked. This allows me to immerse myself into their local culture and traditions, which is of keen interest to me. Many of their cultural activities and traditional habits have also helped me to arrive at solutions for that particular landscape. Also, knowing the Pardhi community has been one of the highlights of my life. I have learnt so much from them. I’m humbled that they have accepted me to be a part of their family and have entrusted me to be one amongst them.

The other high point that I would like to share is the advantage of being a woman in this field. It is easy to break ice with the females in the community and work with them. Having ‘Ek chai ki pyaali’ (a single cup of tea) with them can break any barriers. This has also proven to be a very important tool for me since in most rural areas, I’ve seen women being the biggest influencers within a community. They’ve helped us to bring about a change.

And last but not the least, my experience with working with the Forest Department personnel have been fantastic! I’ve come across some of the most dedicated officers on-field and off-field who are not just committed to doing their jobs but are willing to go that extra mile to make a bigger difference. It’s great to work with such officers when they’re personally determined to bring about a change. Examples like the Kanha Tiger Reserve running the Bhoorsingh Public School & a dedicated women’s canteen, Panna Tiger Reserve supporting the Pardhi hostels and many more such live examples have shown results through support received from the communities.

Room to Roam in Central India

5/25/2020

 
~ by Archita Sharma (WWF-India)

The Central Indian Landscape has been a stronghold for several long-ranging wild mammals for several thousands of years. Its dense forests and rolling grasslands provide a rich holdout for tigers and several other carnivores, big and small, prowling, hunting, and stalking in the shadows of this wild heartland. But over the last century, Central India has lost a share of its forests to growing human settlements, railways, roads and rampant mining. So, a landscape that was once a contiguous expanse of dry deciduous forests is now fragmented, remaining with 34% forest cover, out of which only 8.5% is legally protected.

Long-ranging mammals need room to roam. In many mammalian carnivores, the juveniles move out of their mother's territory to establish their own, with the males moving long distances to find new territories. When their dispersal routes to seek out prey, territory and mates are severed by roads, cities, villages, mining, and railways, natural populations can be isolated into small island populations. These small isolated populations face a higher risk of disease and extinction. Population genetic structure can help us determine the isolation or connectivity in natural populations.

To put it simply, genetic structure captures the level of genetic variation existing in a population. If mammals from different forest patches are mating with each other, they will be genetically more similar and will consequently have a lower genetic structure. Similarly, isolated populations will be genetically more distinct and will have higher genetic structure. Using DNA as a tool, estimating structure and connectivity in mammals can help us understand fine scale impacts of fragmentation. While there are several such studies on tigers, very little is known about how fragmentation impacts other mammalian species.

A new study published in Diversity and Distribution answers how the same level of habitat fragmentation has differential impacts multiple mammalian species in the threatened Central Indian Landscape. Researchers from the National Centre for Biological Sciences (NCBS), Bengaluru, investigated the genetic structure and connectivity in four long-ranging mammalian species — jungle cat, leopard, sloth bear, and tiger. The four species have varying body size, diet and dispersal abilities, and are expected to have species-specific responses to fragmentation. The two major objectives of the study were (1) to understand how the genetic structure is partitioned between these four species and (2) to find out how different landscape features like roads, built-up areas, and human density impact connectivity and dispersal in the study species.
