CEDAR takes to the Radio Waves
As the physician associates the patient with his own cure, so must the planner appeal to the citizen
- Patrick Geddes, 1915
CEDAR and Radio Khushi 90.4 FM have embarked on a four-month radio-series on natural resource management with special emphasis on water security in Uttarakhand. The aim is simple, communicate with local people, give them a platform to voice their concerns and together find locally appropriate solutions.
As CEDAR’s Executive Director Dr Rajesh Thadani once said: “Knowledge limited to academic publication is of limited relevance”. Therefore, CEDAR is striving to find new ways to communicate their research on ecosystem services to the people who use them. Local radio presents an exciting new opportunity for CEDAR to reach out to people who may not use social media. As Dr Singh said “radio will allow us to reach the last corner of the village. These people are at the core of the community and need to have their questions and voices heard”. Furthermore, Dr Singh made the important point that those who are most vulnerable to environmental degradation and climate change are often those who are least connected through modern technology and least able to get their voices heard.
Currently, CEDAR in collaboration with South Asia Institute of Advanced Studies (SIAS), Kathmandu, Nepal is working on Climate Adaptive Water Management Practices and Solutions (CAWMPS) across four cities in India and Nepal, Mussoorie is one of the town that the team is focussing. The three year project is funded by International Development Research Center (IDRC), Canada.
Radio Khushi is a community radio station which uses interactive media to connect, educate and inspire people. A partnership with CEDAR will allow the station to explore socio-environmental issues using CEDAR’s expertise, hear listener’s views and galvanise action. This partnership is being facilitated by Ideosync Media Combine (IMC). IMC aims to use media to accelerate communication and behavioural change for the social, economic and environmental development of communities. This harmonises with CEDAR’s belief in the importance of citizen science in socio-environmental research, only through stakeholder participation can issue be understood and appropriate solutions are found. It is the ‘tyranny of the expert’ which frequently hinders development because when local knowledge is excluded the proposed solutions are unlikely to be locally sustainable.
Together CEDAR, Radio Khushi and ICM have developed a radio-series strategy. An overarching theme of ‘natural resource management’ was settled and issues of water security in small and medium towns in the Himalayan region to be of prime focus.One important point agreed by all partners was the importance of female participation. While women can be some of the strongest activists on social and environmental issues, they are too often left out of decision making. It was agreed that the radio-series would cover the geographical area of Uttarakhand but focus on the regions where CEDAR has the expertise, case study examples and success stories. These include CEDAR’s work climate change adaptation, urbanization and water security.
The first live show was aired Thursday 11th October 2018 and was a great success with Dr Vishal Singh (CEDAR’s Deputy Executive Director) being interviewed by RJ Ashish (Radio Khushi’s Jockey). The programme started by introducing CEDAR as an organisation which focuses on research and research use. CEDAR was founded on the realisation that there is a gap between academics, grassroots workers and planning practitioners, CEDAR aims to bridge this gap through their multi-disciplinary approach. Dr Singh pointed out that many of the NGOs working in the region on socio-environmental issues work in isolation and there is an urgent need for more cross-disciplinary research and collective action. He asserted that citizens play a crucial part in the process, local knowledge is rich and often untapped by ‘scientific experts’. Dr Singh gave a very good example of the importance of traditional knowledge and loss if it is ignored. He explained that there is only one person left in the Kumaon region who knows how to make Naulas, a traditional surface-water harvesting method typical to the hill areas of Uttarakhand. He lamented how good traditional methods have been forgotten and how the adoption of new technology has often led to environmental degradation.
The show also discussed CEDAR specific work. Dr Singh described how CEDAR focuses on the themes of forestry, urbanisation and water biodiversity and wildlife. Regarding water security Cedar is examining how population rise, unplanned development, climate change andtourism are contributing to water insecurity in towns of Himalaya alongside environmental degradation and climate change. RJ Ashish picked up on the climate change theme and described how residents in Mussoorie were noticing the early flowering of the Rhododendrons, delayed monsoon and declining winter rainfall. This is a key example of citizens being able to observe and record change over time. Dr Singh confirmed these observations and asserted that they are a serious concern.
A key point leading on from this discussion was that the rapid drying up of springs and depleting lake levels are a serious problem. Dr Singh said, “springs and lakes are shared resources shared resource to reap the benefits from, but nobody wants to conserve it”. This is a classic example of the tragedy of the commons. Collective conservation and sustainable use are needed urgently. However, it is easy to use buzzwords like ‘sustainability’ and ‘collective active’ but the real questions are how is this achieved and by whom? Perhaps this radio series can be a step towards finding answers to these questions as researchers collaborate with listeners.
It was at this point that a listener phoned in with an excellent question, “if there are so many NGOs working in this area why is there no output?” This question exemplifies the gap between research and the local people. Dr Singh explained that it is not that the work is not being done but that the output is not in the public domain or even when it is, it is not accessible. The accessibility of knowledge is as important as producing that knowledge in the first place.
This led onto a second good question from a listener, they said “to achieve anything citizen support is needed. But Bringing people of different opinions together becomes a challenge. How do you manage it?” Dr Singh explained how this is always a big challenge for CEDAR, for sustainable solutions to be found and successfully implemented policymakers, experts, activists and other stakeholders must all be brought together. However, even when a platform is provided it can be difficult to encourage stakeholders to come. Therefore, research NGOs must strive to make their research accessible. But equally, stakeholders must engage and share their ideas.
Dr Vishal Singh offered a great example of mass stakeholder engagement. In Nainital, the lake is being degraded and a meeting was held with the Chief Minister of Uttarakhand and the people of Nainital. CEDAR laid out their out their research on how the encroachment of Sukhatal lake is disturbing Naini lake level and a decision was made to rectify the problem. “It started with people, it was taken forward by people and then the people helped in the decision-making process of the government” (Dr Singh). The most iconic symbol of this success story was the over 1000 people who undertook a bare-foot silent march around the lake to raise awareness for its degradation and the need for conservation. This is a powerful example of how many people with different opinions can be brought together to create change.
Overall the radio show emphasised that technocratic solutions will only go so far and citizen participation is crucial. This initiativeaims to disseminate CEDAR’s research in an accessible form, reach all corners of the community and bringeveryone into the discussion. If you want to hear CEDAR researchers talk more about their research and address interesting questions from listeners across Uttarakhand, tune in every Thursday at 90.4FM.
Let's Not Wait for a Silent Spring in the Kumaon Himalayas
The Himalayas are no exception. During the last few decades, the rich forests of these great mountains have become degraded and fragmented due to similar pressures. Since 2013, our research team (including Rajkamal Goswami, Munish Gupta, Tarun Menon and Ritobroto Chanda) has been studying the birds of the oak hardwood forests in the mid-altitudes of the Himalayas (1,700 m to 2,400 m).
Oak forests form a fascinating ecosystem with many unique features, not the least of which is the high structural complexity and weather-modulating characteristics. Oak forests are known to be relicts from the Pleistocene epoch, when temperate oak forests covered the Himalayas due to the prevailing low temperatures. The glaciers’ retreat left temperate hardwood forests in their wake, the only ones in a largely tropical country.
These forests generally have few other tree species, with a single oak species dominating at a given altitudinal belt, mixed in with 10-12 other species. Yet the small-scale diversity in the herbaceous flora, shrub community, lianas and epiphytes is immense. In a protected oak forest, the canopy is dense, with some giant trees growing up to 30 m tall. Their complex branching pattern, high density of snags and cavities, presence of mosses, lichens and epiphytes, and a diverse understorey gives rise to abundant niches for fauna.
Forest soils are rich due to old, collected layers of decomposing leaf litter. The Banj oak (Quercus leucotrichophora) is known to be a hydraulic pumping machine, literally drawing water out of the atmosphere. This is responsible for the considerably lower temperatures and higher humidity inside an oak patch, as well as the presence of perennial streams.
Oak forests are no less important for supporting rural livelihoods as well. Local people use the nutrient-rich leaf litter as manure, cut oak foliage for feeding their livestock, and extract fuelwood and numerous food plants. They get their water from clear mountain streams sustained by dense oak cover.
These observations have, over the years, prompted a thought: if the Banj oak could be a keystone species in this system.
Chir pine forest coexists with banj oak at this altitude, but has a much more open canopy thanks to needle-like leaves, barely any shrubs and a drier microclimate. While both forest types are native to the study region, the chir pine is a pioneer species that gradually gives way to hardwoods, including oak, if there are no stressors. There is considerable evidence that chir pine forests have been historically extending their range at the cost of oak forests.
Pine is commercially important because it yields construction timber as well as pine resin. Pine is also more hardy and resilient to habitat degradation as its germination and growth can take place in drier soil and in higher light conditions. In pine forests, there are none of the mosses, epiphytes, lichens or leaf litter depth to complicate the vegetation structure. But in Kumaon, oak stands have been transforming to pine under anthropogenic stressors, a sort of backward succession process.
Structurally complex oak forests could very well be the key to survival of faunal diversity in the Himalayas, in the face of prevailing land use change. Since May, we have been undertaking systematic bird counts in about 200 sites located within the oak-pine forest belt, equally distributed among six different kinds of land use: protected forest, partially degraded forest, heavily lopped forest, cultivation, built-up tourist areas and pine forest.
Our surveys took place within a window of 20 km by 20 km located in Nainital and Almora districts (Uttarakhand) and limited to the pine-oak forest belt. Winter counts have also been undertaken to see if the patterns of species distribution changed considerably in that season. Given the harsh winters, with sub-zero temperatures, one would think that most bird species would need to migrate downhill to meet their energy requirements. If they do not migrate, then what are the plant and insect resources that allow them to cope?
While our data is still being collected, some interesting results have been unearthed, with some of my intuitions being borne out. We found the Banj oak to be a highly diverse forest ecosystem, with over 160 species recorded so far. Surprisingly, as many as two-thirds are breeding birds (either summer migrants or year-round residents). There are relatively few vagrants, passage migrants and winter migrants in this habitat.
The breeding activities of birds in the summer showed how important the mosses and lichens were for nest-building. Every little tit, flycatcher, nuthatch and dove was seen carrying these materials. A large number of shrub species bloomed and bore fruit in the spring and summer, providing abundant food for breeding birds. The oak forests rang with a medley of birdsong in this season. During this time, we also realised the significance of leaf-litter for bird survival in winter. In protected oak forests that retained a rich layer of decomposing leaf leaves, the white-throated laughingthrush and grey-winged blackbirds were able to continue foraging. Further, the complex vegetation structure supported insects
Our observations also show that there is a rich variety of plant resources that support breeding residents through winter. Oak acorns, veritable packets of nutrition that ripen during winter, seemed to be important food for some of the larger bird species, such as the Kalij pheasants, white-throated laughingthrushes and Eurasian jays. We also witnessed fruiting in tree and shrub species that provided much needed resources for birds in a sequential pattern as the winter progressed. Importantly, only protected oak forests retained the diversity of shrubs and trees that could support avian foraging to this extent.
The impact of land use shines through in our data. A preliminary analysis showed that species diversity of birds drops drastically along the use gradient, with protected oak forests estimated to harbour 70 species, and the built-up and pine sites being the least diverse, both at 49 species. The number of forest specialists drops drastically, too, from 32 in protected oak to six in built-up sites. (The latter group includes the white-throated laughingthrush, black-faced warbler, rufous sibia, chestnut-capped laughingthrush, rufous-bellied woodpecker, greater yellownape, scaly thrush, brown wood owl and the rufous-bellied niltava.)
However, there still are a number of adaptable forest species that appear to use human habitats when the opportunity arises, while nesting in protected forest habitat. While the latter category of avifauna is relatively adaptable, being able to use resources in forest edge habitat and cultivation, they still require high quality forest habitat to survive. (This group includes the whiskered yuhina, brown-fronted woodpecker, ultramarine flycatcher, grey-winged blackbird, streaked laughingthrush, great barbet, green-tailed sunbird and the red-billed blue magpie.)
Our findings also confirm the oft-repeated prediction that pine forests support less species diversity than oak, and do not harbour the stable bird communities. Community-managed forests also seemed to support biodiversity as much as protected forests do, as long as they had good forests nearby or were moderately used.
We categorised each bird species according to its breeding and migrant status, degree of forest specialisation and geographic endemism, in order to better understand vulnerability. According to our analysis, species that are breeding residents, forest-specialised and also endemic to Himalayas will be the most vulnerable to extinction in the event of hardwood forest loss. Among them is the rufous-bellied woodpecker, a species that partially feeds off tree-sap and hardly strays out of dense oak forest, and the common hill partridge that forages only in dense forest with deep litter layer. The less conspicuous Himalayan shrike-babbler and the striated laughingthrush are other identified vulnerable species.
There are huge implications of our findings for conservation planning. If the area of protected oak forest habitat declines further, we will likely lose the majority of our forest specialists. As the other land uses are considerably less diverse than protected oak, landscape-level diversity will go down as well. Further, the forest-specialised Himalayan endemics that are also resident in oak forest are likely to be the first to suffer, given their narrow altitudinal ranges and vulnerability to degradation.
Our analysis is still in very early stages, but it does appear that we have explored just the tip of the iceberg. The ultimate goal of our study is to understand how Himalayan birds survive and cope with the twin threats of land-use change and global warming. Studying this is all the more urgent as there will likely be synergistic effects between land-use change and climate change, with each amplifying the negative effects of the other. Such synergism shows up in the breeding populations of plains species such as jungle babblers, rock pigeons and red-vented bulbuls in cultivation and built-up tourist areas at altitudes beyond 2,000-2,200 m above sea level.
Could such land use be catalysing the upward movement of generalist bird species ranges in the middle Himalayas, as the climate gets more conducive to plains and foothills species? This remains a question for future research.
From our data, it is clear that intensive bird surveys across different landscapes are required within each altitudinal belt in the Himalayas if we wish to understand these phenomena even half-way. Further, the role of plant diversity in supporting high bird diversity should be explored because the diversity of plant species in hardwood forest enables bird survival throughout the year as well as long-distance migrations to continental Asia.
Birdwatchers and scientists need to join forces to explore these issues more systematically and widely. The expanding tribe of birdwatchers in India could be recruited to help with some of these projects. For instance, just a few days of systematic birdwatching, repeated every year in the same sites, can lead to useful insights the way the Breeding Bird Survey in the US has.
For now, our team is studying one vulnerable group in detail in these forests – the woodpeckers – to understand the habitat factors that underlie their occurrence and abundance at this altitude and the variation of these factors with season and human use. There ten species recorded in this forest association, and most appear to be breeding residents. Our team is also actively uploading birdlists onto the e-Birds portal to help expand our knowledge of rare-bird distribution and habitat in the middle Himalayas.
We cannot afford to wait for a silent spring before we begin our surveying. Armed with the right combination of natural history expertise and quantitative modelling, we may just be able to preempt local extinctions of largely under-studied bird species in the fragile Himalayan forests.
