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.

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.

A timely study by NCCI founder Prof. Ruth DeFries and collaborators lays out possible scenarios for minimizing risk of exposure to COVID-19 in rural India as the lockdown is relaxed and migrants return to their villages.
 
What we know
Seasonal migration is a widespread livelihood option for households in forest-fringe areas of Central India, moving people from villages to the country’s cities for up to 6 months in a year. Typically, these migrants are young males and they return to the village in time to plant monsoon crops. Seasonal migrants are generally poorer and less educated than those that migrate permanently (for work or education) [1]. In the current pandemic of COVID-19, the risks of exposing rural India with returning migrants from cities is of major concern for both rural communities and government authorities, as well as for migrants who are desperate to return with no source of income during India’s lockdown.
 
Moreover, communities on the periphery of forest areas in the country are some of the most vulnerable and poorest. Central India, one of the main forested areas in the country, is important for tiger conservation and has a high proportion of Scheduled Tribe populations. In these villages of Central India, the poorest households use seasonal migration to supplement their incomes [2], increasing the risks of exposure to COVID-19 as migrants return. These villages are even more at risk as they have poor or non-existent health facilities and low quality diets in typically crowded households [3]. Additionally, most households continue to use fuelwood with high indoor air pollution already causing respiratory problems [4]. While the populations are not as dense as in cities, the spread from village to village and lack of medical facilities is a grave concern.
 
As of this writing, the country has been in lockdown since March 24th. Seasonal migrants are unable to access work or means to return home. News channels have documented migrants returning home on foot. Quarantine facilities have been set-up in villages but the quality and efficacy of these are unknown. The government restricted inter-state travel for migrants after April 20th. As restrictions ease, chances persist of exposure and spread to adjacent villages from migrants who have already returned.
 
Given the economic hardships of lockdown, the authors of this study provide some alternatives to severe physical distancing.  The objective is to reduce chances of exposure while allowing people to obtain essential supplies, plant crops, and carry out other necessities of daily life. A post-COVID-19 path could be informed by their results.
 
The study uses data from a 2018 study that surveyed approximately 5000 households in 500 forest-fringe villages in Central India. The original study was to assess patterns of migration over the previous five years (2013 – 2018) and was unrelated to tracking disease spread.
 
What they found
The researchers found that seasonal migration is widely dispersed across forest-fringe villages of Central India.  Eighteen percent of surveyed households sent migrant workers to cities in the last five years.  Seventy-five percent of villages had a least one household with migrants, and all districts had a least one village with migrants.  Similarly, migrants traveled to 124 locations over the last five years. Over eight percent of migrants went to cities were COVID-19 cases were reported at the beginning of the lockdown, based on the publicly-available COVID-19 tracker site (www.covid19india.org).

The researchers used a simple, epidemiological model of disease spread to examine different scenarios of movement between and within villages (Figure 2).  Using varying R0 values (the basic reproduction number that represents the expected number of cases generated by an infected individual), the researchers allowed for scenarios with lenient (no restriction R0=3), moderate (some restriction to interactions R0=2) and maximal (highest restriction R0=1) movement within and between villages. The findings highlight how different strategies for easing lockdown restrictions might vary in terms of the number of people exposed in the unlikely but possible event of the virus reaching a village.

The most effective way to limit exposure is obviously to keep everyone within and across villages in lockdown. But as most Indians are now familiar with, keeping an indefinite lockdown is not feasible with many states already easing some restrictions to save India from economic hardship. The more important question then becomes, how one would begin opening up the lockdown or easing restrictions to balance the economic needs with necessary caution to avoid exposure to the virus.

This study reports, for a hypothetical case of exposure in one village, that maximal limitations to movement between villages with lenient movement within villages (middle scenario in Figure 2) exposes fewer people than moderate restrictions that apply to both within and across villages (bottom scenario).

Incidentally, the scenario that led to the least number of exposed people in the model is similar to New Zealand’s successful “social bubble” and communities’ efforts in India to restrict entry to villages.

The rusty-spotted cat is endemic to the Indian subcontinent; found in India, Nepal and Sri Lanka. Little is known about the ecology of this smallest of the world’s felids, and this combined with it’s rarity have warranted it being listed under ‘Schedule I,’ of the Wildlife Protection Act of India (1972). This is the same category of protection as the tiger and Asian elephant, which means that hunting or trading in it’s body parts can result in up to 7 years of incarceration for the guilty.
 
Until recently, it was considered as ‘Vulnerable,’ by the IUCN, but an increase in it’s occurrence records in different habitats in India and Nepal has seen it down-listed to ‘Near Threatened.’ However, even the most basic aspects of its biology, such as its habitat requirements, home range characteristics and diet remain unknown; these are crucial for conservation planning. A recent study provides a broad understanding of this species’ habitat preferences.

Kanha Tiger Reserve (KTR) in the central Indian highlands is the site for this study. The reserve harbors a mosaic of vegetation types, including; meadows and woodlands in the valleys (dominated by Sal Shorea robusta), hilly tracts of dense mixed deciduous forests and hilly plateaus with extensive grasslands. It also contains numerous perennial streams and ponds that support swamp vegetation. Kanha is a heaven for a whole suite of globally threatened species such as the endangered tiger and dhole, and vulnerable leopard, gaur, sambar, four-horned antelope and endemic hard ground barasingha deer.
