Chhirak Maya Rai, aged 82, has lived all her life in Ward-8 of Dhankuta District, nestled in the mid-hills of Koshi Province, Eastern Nepal. A revered member of the Aath Pahariya Rai, an Indigenous community native to Dhankuta, Chhirak Maya Rai has witnessed remarkable changes throughout her life, though water was never an issue in her community. The resilience of her community has been put to the test by an unprecedented water crisis that has been unfolding over the past few decades.

"I am 82 years old now, and this is the first time I am taking any training on water management and sanitation” says Chhirak Maya Rai, a member of the Aath Pahariya Rai community in Dhankuta.

Springs are a major source of water in the area; however, like other mid-hill communities across the Himalayan landscape, neighbourhoods in Ward-8 have direct experience of the springs drying up.

Not so long ago, the Aath Pahariya Rai was a thriving community, carrying on their way of life that had remained unchanged for generations. Once known for its ample water resources, Ward-8 has now become synonymous with aridity, becoming one of the driest wards in the entire Dhankuta district. The people living here, including Chhirak Maya Rai, face relentless challenges posed by this profound water crisis.

The drying up of springs has many severe consequences for the sustainability of Himalayan landscapes, river systems, ecosystems, and biodiversity. This scarcity has infiltrated into every aspect of life in these communities, reshaping the way of life as the loss of water sources has made it increasingly difficult to cultivate land. Many men are forced to move out in search of work, leaving women and children to make up for the missing labour force; this increases the drudgery of women and children. For instance, in Khambela village, once known for its many cash crops including tomato and beans, the water shortage has become so acute that residents can only fetch water once every four days – a task which takes at least 2 hours each time. This means they can no longer grow cash crops and can only cultivate species which need the least amount of water. Production overall has decreased significantly. With climate change exacerbating the situation, it is crucial to understand the characteristics of water and the value of every single drop for sustainable water management. Managing water sustainably entails ensuring a sufficient supply and responsible use of water for people, animals, farming and business, to meet the needs of current and future generations.

The remoteness of the location also adds to the daily difficulties of communities such as Ward-8, Dhankuta Municipality, “We live 20 minutes away from the main bazar yet very far from opportunities and access to facilities or resources,” says Sanjita Aath Pahariya Rai, describing the journey by vehicle.

Tackling the issue head-on

Dhankuta Municipality recognises the need for planned investment in managing the watershed – the area of land that drains or sheds water into a specific waterbody. A watershed management approach would result in extra ground water storage and flow, thus ensuring a regular supply and encourage responsible use of water and other resources for domestic, agricultural, and development purposes on an equitable basis.

An interdisciplinary team of experts on watershed and river basin management, community-based adaptation, Nature-based Solutions and environmental management and impact assessment from ICIMOD provided technical support to the Nibuwa-Tankhuwawatershed management plan, which the municipality started implementing in 2021. The plan focuses on six major components: i. Sustainable conservation, management and use of water resources, ii. Sustainable land use management, iii. Diversification and improvement of livelihoods options, iv. Climate change, disaster risk management and sustainable infrastructures, v. Strengthening institutional mechanisms, and vi. Interdisciplinary action research and extension.

The ICIMOD team’s long-standing partnership with the Dhankuta Municipality seeks to address these issues head on. Following preparation of the Nibuwa-Tankhuwa Watershed management plan, we are now supporting the implementation of the interventions proposed in the plan.

Water smart solutions for water conservation and management:

It is crucial that our scientifically proven interventions incorporate what is feasible for the Dhankuta region: our answer is in ‘water smart solutions’.

A water smart solution is an approach or technology that improves water management and efficiency, ensuring sustainable and responsible use of water resources. It integrates innovative technologies, data-driven systems, and sustainable practices to optimise water usage, reduce wastage, and enhance overall water resource management.

Considering the efficiency and sustainability of water smart solutions, we initiated three activities in Dhankuta Municipality to address the water crises: rainwater harvesting, groundwater recharge activities and a programme to plant vegetation.

Rainwater harvesting is the process of collecting and storing rainwater to meet future water needs. We installed rainwater harvesting systems in two locations in March 2023, working with our partners on the ground, mainly Dhankuta Municipality, Kathmandu-based company SmartPaani Pvt. Ltd., which promotes, develops, and installs water-related technologies, and HUSADEC Nepal, an NGO whose focus is on advocacy and development work with vulnerable and excluded communities in Nepal. This system conserves up to 10,000 litres of water to meet the water needs of 20 households. The other system installed in a school will store up to 1,000 litres. These interventions will help reduce water stress but also inform the community of alternatives to address water scarcity. With use of an effective filter, the conserved rainwater is also fit for drinking. We were able to distribute ‘Tripti Water Filters’ – tabletop filters with four distinct levels of filtration for safe drinking water – to 20 households of Aath Pahariya Rai, Khambela village.

In Khambela village, we can see the fruition of these interventions – we moved the water source closer to the community, which reduced the time people spent collecting water from four hours to a few minutes. During our follow-up visit to the community in May 2023, we were greeted by a pleasant sight surrounding the water tanks – happy faces, mostly women, as they waited their turn to collect water in their empty pots and jerrycans from the tanks that had collected water from the previous three days of rain. We could see how these women, their shoulders once burdened, now stood tall. “We feel we have a newfound sense of strength and freedom,” said Rahan Shwori Rai. The transformative power of water, harnessed through our collective efforts, has substantially reduced the drudgery of women in this village, whilst having a positive impact on the time used for such tasks.

Springs revival – ground water recharge

One of the major drivers of the water crisis in the area is the drying up of springs, which is the main source of water. Of the 97 springs mapped in the Nibuwa-Tankhuwa watershed, 23 were completely dried up. The water flow or ‘discharge’ from the remaining springs continuously decreased, leaving residents worried about the future of their water supply.

To address this growing challenge, the ICIMOD team used our six-step protocol for spring revival and management. With this proven framework in hand, we set out to revive two critical sites in the watershed: Suke Pokhari in Ward-1 of Dhankuta municipality and Dhoje Danda in Ward-2 of Chhathar Jorpati rural municipality.

We dug 50 trenches in the Dhoje Danda area to collect rainwater and runoff for groundwater recharge, and rain gauges were installed on sites to collect rainfall data. These gauges provide important data on rainfall and discharge both before and after the intervention, a useful tool to track the impact of our work.

“Traditional ponds and flowing springs were once plentiful, but today they’re a rarity. As a result, we’re facing a severe water shortage. Through capacity building, we now understand the importance of groundwater recharge and linking traditional ponds with springs.” –  Krishna Kumar Thakuri, Ward-1, Dhankuta Municipality.

Planting campaign

What’s next? Keeping the area green with native vegetation is another main activity that is crucial for the success of our Nature-based Solution interventions. Nature-based solutions (NbS) are those actions which encourage the protection, sustainable management, and restoration of natural or modified ecosystems to address societal challenges while simultaneously supporting human wellbeing and biodiversity benefits. We launched a large-scale campaign to plant trees, plants and shrubs in Dhankuta, together with a comprehensive selection of local stakeholders including: local government (Dhankuta and Chhathar Jorpati Rural Municipality), Federation of Community Forestry Users Nepal (FECOFUN), Division Forest Office, Soil Conservation and watershed Management Office. Working with our partners on the ground, we were able to take on the critical task of ground water conservation and revival.

Over 1000 participants planted 46,000 seedlings and saplings of 22 different native species across various areas identified through careful field data analysis and stakeholder consultations, making sure that every tree was planted in a spot that would have the most impact. Even a small patch of green can go a long way in promoting healthy ecosystems and maintaining sanitation at the source.

Impact and sustainability of water smart solutions

Although we have seen immediate benefits of the rainwater harvesting system in Dhankuta, the long-term goal is to reap the full benefits of the other interventions – spring revival and tree planting. Moving ahead, we need to analyse the economic and social value of our ongoing efforts. These are two critical aspects of any watershed management. Having a clear understanding of the economic and social value of these interventions can help us make better decisions on the benefits for people, the economy and nature. Hence, monitoring the ongoing project activities including rainwater harvesting, planting, and groundwater revival activities is critical for the solutions to be sustainable in the long run. Funding for such water smart solutions needs significant improvement as they promote sustainability and effective water resource management in various sectors, aiming to balance increasing water demands with limited supply while mitigating environmental challenges and population growth.

On Thursday in New Delhi, India’s Joint Secretary of the Ministry of Environment, Forest and Climate Change, Ms Nameeta Prasad, convened the second meeting of the ICIMOD National Coordination Committee in India.

The National Coordination Committee has been created to serve as the key body to guide, drive and coordinate plans and programmes co-developed with ICIMOD in India, and the meeting brought together key stakeholders from central and state ministries, academia and other stakeholders.

At the event, Joint Secretary Prasad praised the body’s “comprehensive mandate”, saying it would “serve as the hub for scientific solutions in the Himalayan region” and “play a vital role in addressing pressing environmental challenges.”

ICIMOD Director General Pema Gyamtsho welcomed the deepening of ties with India the meeting signified, with its implications for “the scope, scale and ambition of the work we might be able to deliver as a result.

“Everywhere we look, we are seeing the rapid and escalating threats faced by the Hindu Kush Himalayan region. This meeting is a crucial step not just in reinforcing the Government of India’s longstanding commitment to ICIMOD, but in recognising the need for closer coordination and greater collaboration to drive faster progress to reduce risks, and protect people and investments in this crucial mountain biome.

“The NCC puts this important work on a much firmer footing, and will enable us to work in a more streamlined way with key strategic partners and identify more opportunities to join forces to have faster impact.”

Along with a strong delegation from India’s MoEFCC, whose secretary represents India on the ICIMOD Board of Governors, the event was attended by Dr Sunil Nautiyal, Director from Govind Ballabh Pant National Institute of Himalayan Environment (NIHE), ICIMOD’s focal institution.

Also represented were state governments of Uttarakhand, Arunachal Pradesh & West Bengal, the Ministry of Tourism and Ministry of Home Affairs, the Ministry of External Affairs, the Ministry of Earth Sciences, the Ministry of Skill Development and Entrepreneurship, WWF India, Unesco India, Niti Aayog, G.B. Pant National Institute of Himalayan Environment, National Institute of Urban Affairs Gandhi University, Sikkim University, JNU, and North-Eastern Hill University.

The National Coordination Committee for Transboundary Landscape programmes in India was established in 2018. Following the publication of the HKH Assessment Report and country consultations held to firm up the HKH Call to Action, its mandate was widened in 2021 to include all ICIMOD programmes in India.

Springs are drying up across the Hindu Kush Himalayas (HKH). This is a cause for serious concern for mountain communities whose lives and livelihoods depend on spring water. 

In 2018, half of the estimated three million springs in the Indian Himalayan region had either dried up or had reduced flows, as reported by the country’s apex policy-making body, NITI Aayog. About 35 per cent of 6,555 water sources in Bhutan were drying up, a recent assessment found. 

This is also the case in Nepal, where over the past 10 years, approximately 20 per cent of springs have dried and 50 per cent of springs have experienced a decrease in spring flow. This is particularly acute, as an estimated 10 million people in Nepal depend on spring water for drinking, household use and minor irrigation. 

Governments must invest in promoting science-based and socially inclusive management of springs in the hills and mountains of the HKH. This public investment in anticipatory adaptation is necessary to build resilience against climate change and other evolving threats to water security in these areas. 

Hard engineering and hubris

The standard approach to addressing water insecurity in hill and mountain settlements is to tap a nearby source and deliver it to users. This hard-engineering approach, which, although well intentioned, is unsustainable in a context where water sources are drying up everywhere. 

Water projects centred on only delivering engineering solutions are concerned about the source, not the resource. Typically, as a project becomes inadequate or begins to fail, the scale of the response, both in terms of cost and engineering, is raised. 

As a result, growing urban centres in the hills and mountains are laying disproportionate claims on water resources from their hinterland, creating what has been described as “rings of dryness” around them. This is typical of a hard-engineering approach, where tapping water from distant sources is justified by demand and the disproportionate heft of urban power centres. 

In contrast, the springshed management approach focuses on resource sustainability and community stewardship, keeping in mind growing water needs and even anticipating disputes around future water needs. 

Springshed management involves not just the management of the sources (springs) but also the recharge area, through which water infiltrates and reaches the aquifers, where groundwater is stored and emerges at the surface as a spring. 

However, not all big hill and mountain towns can be supported through nature-based solutions like spring revival. For instance, a large city like Nepal’s capital, Kathmandu, which sits in a bowl-shaped valley, would continue to be dependent on inter-basin transfers to meet its needs. 

However, several areas along the valley rim could be self-sufficient with water from springs in the adjoining hills and decouple from the main supply systems, reducing overall demand.

Such large investments must also be viewed against the backdrop of demographic change in the hills and mountains across the region. As mountain settlements become increasingly depopulated due to outmigration to larger urban centres within the same countries or to other countries across the region and globally, we need to revisit the scale and viability of engineering projects. 

In this context, an appropriately scaled nature-based solution like spring revival is a better investment of public resources, with a clear restoration plan and the necessary infrastructure to deliver sufficient safe water for household use and minor irrigation, in a way that reduces the time and effort needed for the communities to collect and use it.

Investing for multiple benefits

Investing in spring revival as a nature-based solution not only improves local water security, but it also delivers important co-benefits. Landscape restoration, conservation of aquatic and riverine biodiversity, contributions to streamflow in non-glaciated catchments, (that is, areas of land where runoff, or water flow, doesn’t come from glacier meltwater) and sustaining winter and dry season flows across numerous river basins of the HKH are some of them. 

Combining spring revival with already-built infrastructure could potentially restore the value of dead investments in cases where the source has been degraded. This could prevent putting good money after bad investment and cut government spending, enabling investment in other critical infrastructure.

Community-based spring revival could also guard against maladaptation, since it involves groundwork and community mobilisation, blending science with local knowledge and building inclusive community institutions rather than a one-off project that only focuses on an engineering solution and distorts local understanding of resource availability. 

For instance, maladaptation here could refer to an increase in cultivating water-intensive crops just because a project is delivering water. At the landscape level, investments in spring revival can bring communities together in complex geographies, such as when one community’s spring recharge area is located within another community’s land or forest. 

Such collective action can forge landscape-level conservation partnerships and yield important conservation outcomes. 

Investing in community agency

To address the issue of water stress due to the drying up of springs across the mid hills and mountains of the HKH, we have collaborated with partners to revive springs and advance springshed management based on a six-step protocol that combines hydrogeology (geology that deals with underground or surface waters) with social science methods and community-empowering participatory action research. 

There are three aspects of this work aimed at building autonomous water security in hill and mountain settlements. The first is knowledge co-creation, which involves communities working with interdisciplinary teams of hydrogeologists, social scientists and foresters. They also work with experts in watersheds — the area of land that drains water into a specific waterbody. 

Village Water Security Plans are co-designed using participatory tools, combining traditional knowledge with hydrogeology, identifying recharge areas for restoration and facilitating cooperation among communities inhabiting the springshed area.

The second aspect is the creation of a cadre of ‘para-hydrologists’ from within the communities who, although not formally trained in hydrology, receive training in monitoring and collecting data on spring flows and on mobilising communities to take part in activities designed to revive groundwater or springs. 

Such activities include springshed restoration, including physical works like digging trenches or afforestation or developing measures or structures that store and buffer rainwater. 

The third focuses on building water user groups, village water security plans and embedding springshed management within local institutions and plans that is inclusive — ensuring that women and socially marginalised groups participate in and have a say in spring revival and water use. 

The results of our work with partners in Bhutan, India and Nepal show improved spring flow, demonstrating an inclusive and sustainable model that can be upscaled to enhance water security across the HKH.

Alternative hard engineering solutions are often made and influenced by narrow interests and political considerations; as such, they undermine the agency and decisions of local communities. 

A community-based approach to springshed management reduces the chances of ‘elite capture’, that is, where public resources are biased for the benefit of a few individuals of superior social status in detriment to the welfare of the larger population and socially marginalised groups are excluded from benefits. 

By supporting collective action, spring revival as a nature-based solution can improve local resource conditions, resilience and social cohesion within the community.

Investing in anticipatory adaptation

Our research shows that spring revival enhances water access, improves livelihoods and contributes to countries achieving several Sustainable Development Goals. 

While dry springs and water stress receive attention and investment, our focus needs to quickly shift from source management to resource management with simple, low-cost, nature-based solutions instead of unsustainable and high-cost engineering solutions. 

Many springs are drying up or becoming seasonal, indicating widespread water stress in the not-so-distant future if we do not act now. This is an impending crisis, so instead of resorting to quick technical fixes, we must invest in nature for long-term water security. 

In 2019, ICIMOD published the Hindu Kush Himalaya Assessment, the first definitive regional report on the status and future of the region that it is our mandate to protect. The report was crucial in forging a consensus among policymakers both regionally and globally about the climate vulnerability and significance of the people, nature and ecosystems within these mountains and its findings continue to guide much of work.

Importantly, in articulating the rapidly increasing magnitude and complexity of regional and transboundary challenges this region will face, it also paved the way for a complete reshaping of ICIMOD itself – the key overarching task to which ICIMOD committed itself in 2022.

With the full backing of our regional member countries, we embarked on an extensive consultation with governments, donors, partner institutions, and staff to ensure that the institution is fit-for-purpose for the decades to come. We are grateful to all our partners and supporters for their crucial contributions to the dramatic phase-shift this interrogation of our work and future direction has already unleashed. 

Our Strategy 2030: Moving Mountains, the fruit of this consultation, made it abundantly clear that the escalating effects of climate change, water insecurity, increased disaster risk, biodiversity loss and widespread socio-economic change required transformative action, and that ICIMOD itself needed to overhaul its processes and focus to meet these needs.

Alongside our fifth medium-term action plan (MTAP V, 2023-2026) our Strategy outlines how we will rise to meet the challenges ahead – transforming ourselves institutionally to be agile and responsive, resetting our portfolio and reorienting all our work to focus relentlessly on impact. Both documents were informed by our gender audit and quinquennial review and align with the stated priorities and global commitments of our RMCs. 

Being fit for purpose | Our new structure

At the centre of this work has been the shift to a more streamlined structure: organising ourselves into three Strategic Groups (SGs) and six Action Areas (AAs), through which we will deliver our results, supported by a new resource mobilisation team, a revamped gender, equity and social inclusion and monitoring and evaluation functions, and much more ambitious communications, plus a commitment to build our digital and innovation capacity.

Strategic Group One: Risks – cryosphere, rivers, air

We are dealing with new and complex risks in our region, including cascading risks. Our work under Strategic Group 1 – Reducing climate and environmental risks – will focus on assessing and managing risks related to water, cryosphere, and air, especially those that are transboundary in nature. We aim to improve understanding and communication of risks, the testing and piloting of solutions, building regionally consistent and informed risk management strategies in varied hazard and vulnerability contexts, and strengthening institutions, policies, and actions for clean air. Our air pollution workstream will focus on co-developing and scaling cleaner and socially responsive air quality solutions and investments for reduction of air pollutants, while continuing to support RMCs in the uptake of solutions and air quality monitoring and assessments.

Strategic Group Two: Economies – landscapes and livelihoods

Scientists estimate that this decade is our best and last chance to save the planet from irreversible damage. Our work under SG 2 – Shaping green and inclusive mountain economies – focuses on understanding the implications of rapid socioeconomic, climate and environmental change on mountain livelihoods and delivering inclusive solutions for marginalised mountain communities. Our focus is on nature-based solutions and incentives for conservation stewardship, with indigenous peoples and local communities being key to achieving conservation targets for the decade. Our work on scenarios, anticipatory adaptation, and human settlements addresses emerging challenges created in the fast-changing climate and socioeconomic contexts of the HKH. Lastly, we will work to support and build the field of green livelihoods and enterprises, nurturing and sustaining inclusive, green, energy efficient, and circular businesses in the HKH.

Strategic Group Three: Advocacy – global and regional

The HKH still fails to command anywhere near the attention, or investment, that is commensurate with its significance or fragility. It is crucial we redouble our efforts to raise awareness of the unprecedented and largely irreversible threats the region faces by contributing to global processes, increasing our capacity to respond by building new alliances, and attracting greater resources to the region. Our work under SG 3 – Enabling regional and global mechanisms for sustainable action – focuses on strategic regional cooperation and collaboration to shape the global agenda and advocate on mountain issues in regional and international processes pertaining to climate, environment, and development. Together with enhanced global outreach on these issues, the work here will focus on building recognition of the HKH in global forums to attract investment in priority areas through our ‘Mountains of Opportunity Investment Framework’ and deliver a high-level institutional mechanism for regional cooperation and collaboration based on the models of Alpine Convention, Arctic Council, and the Carpathian Convention.

From outcome to impact

Rebuilding an institute of the scale and complexity  as ICIMOD has not been without challenge. But this period of intentional interrogation, strategizing and change-management has left us with greater solidarity, accountability, and purpose than ever – and with an ICIMOD that is genuinely fit-for-purpose for the challenges ahead.

We are grateful to all our partners, donors and communities who have helped us achieve what we have in this plan period. While we reflected on the positives during the planning process, captured in the stories in this report, we encouraged honest feedback on shortcomings and areas for improvement. Based on the feedback and advice, we have created an MTAP that pushes us to be purposeful and responsive, and yet adaptive and agile, ensuring that we can better respond to and capitalise on emerging opportunities, thus enabling our work to move forward in stages from outcome to impact. 

We are thankful to our Board and ISG members, focal ministries, partners, and donors for contributing to this vision for the decade, endorsing our Strategy 2030, and setting us on this path. We look forward to your continued support and guidance.

Assam, the largest economy in India’s northeast region, is home to some 2,000 brick kilns, many of which are unregistered and operate using traditional methods such as the ‘Fixed Chimney Bull’s Trench Kiln’ (FCBTK) and some clamp burning which are energy inefficient and polluting. As the brick-firing season kicks off every year, brick kilns on the outskirts of Guwahati, Assam’s state capital, belch out thick black plumes, made up of harmful particulate and gaseous air pollutants. The Pollution Control Board of Assam (PCBA) is keen to reinforce the central Indian government’s revised emission standards for the brick sector, which requires the brick sector to adopt the cleaner zig-zag technology as opposed to traditional methods. Zig-zag technology promises cleaner and more efficient burning of fuel, resulting in better-quality bricks.

Of the 2,000 brick kilns operating in Assam, hardly 20 have made the government-mandated switch to zig-zag technology. This technology involves stacking unfired bricks in a zig-zag pattern; when the bricks are fired, the air plumes are regulated in a zig-zag pattern, allowing a longer interaction with the stacked bricks and better heat transfer. This results in more efficient combustion, cleaner emissions, and ultimately, better-quality bricks. By adopting the cleaner zig-zag technology, brick entrepreneurs can save up to 20% on coal, and yield up to 90% ‘class A’ bricks which are top quality and demand the highest price, while also reducing emissions.

In March 2023, a team from ICIMOD comprising air quality specialists partnered with PCBA to organise a training on zig-zag technology for state pollution board officials and brick entrepreneurs from Assam, and other northeastern Indian states, Arunachal Pradesh, Meghalaya, and Tripura. At the three-day training, we introduced technologies and practices that can help replace traditional and polluting methods in brick kilns. The training covered theoretical and practical aspects, including raising awareness on the economic benefits of zig-zag technology; reducing fuel consumption and emissions; and operating the zig-zag technology, including firing, stacking, fuel selection, and application. In addition to ICIMOD and PCBA resource persons, two master trainers and brick entrepreneurs from Nepal led the training – Bikram Ratna Bajracharya and Rajkumar Lakhemaru – with the Nepal Federation of Nepal Brick Industries (FNBI).

“Done right, zig-zag kilns belch out white smoke, as opposed to black smoke from traditional kilns,” says Rajkumar Lakhemaru, a veteran brick entrepreneur with 40 years of experience under his belt.

White smoke, which is indicative of more complete combustion, is often considered ‘cleaner’ than black smoke – a sign of incomplete combustion, resulting in lower heat and more visible pollutants. In the specific context of brick kilns, white smoke is preferable to black; however, we we must remain mindful that all combustion of fossil fuels pollutes the air, and white smoke does contain pollutants.

Notwithstanding, zig-zag technology is proven to be more efficient, thus reducing the amount of fuel burned and the time that combustion takes place. Since adopting zig-zag technology, Rajkumar Lakhemaru has not looked back since.

Besides imparting theoretical lessons, the two master trainers also demonstrated correct zig-zag brick-stacking and brick-firing techniques in the field at the HMB brick unit in Chandrapur, Assam. Though the HMB unit was an early adopter of zig-zag technology for their kiln, they still struggle to produce quality bricks or reduce coal consumption.

Pankaj Gupta, owner-operator of HMB brick unit and a participant at the training confides that their experiences with the zig-zag approach have been sub-optimal as they lacked the technical know-how in operating the technology.

He says, “The training was a definite eye-opener for us. Our fire masters and brick-stacking supervisors observed the right techniques in-person and will be able to train other brick workers. Through this intervention, we will be able to benefit fully from the technology.”

In view of the new legislation/directive from the central government of India and PCBA, brick entrepreneurs must retrofit existing FCBTK to zig-zag technology soon. Consequently, participating brick entrepreneurs actively sought inputs on retrofitting existing kilns to zig-zag, stacking and firing techniques. They appreciated experience sharing by FNBI master trainers and reached out to ICIMOD resource persons for training materials on the technology.

ICIMOD’s Senior Atmospheric Environment Specialist, Bidya Banmali Pradhan, shares that this model of south-south learning worked well in Nepal and Pakistan. Both Lakhemaru and Bajracharya have experienced the technology work first hand and are the best available promoters. With support from ICIMOD, they trained fellow brick entrepreneurs in 10 cities across Pakistan in 2018.

“This model to promote zig-zag technology was a resounding success in Pakistan. Therefore, we are scaling this approach in Assam,” she adds.

The workshop was a great success, with enthusiastic participation from the brick entrepreneurs, and participants commended PCBA and ICIMOD for the training. The local media also covered the event, helping to spread awareness about the importance of sustainable and efficient brick-making practices.

“This training is a good step forward in raising awareness on the need to switch to the cleaner zig-zag approach,” says Shantanu Kumar Dutta, Member Secretary, Pollution Control Board, Assam. He adds, “We will work with ICIMOD to develop guidelines for brick entrepreneurs to adopt the technology.”

Overall, the workshop and training session was an important step towards promoting sustainable and efficient brick-making practices in Assam and beyond. Our collaboration with the PCBA and the brick entrepreneurs, has laid the foundation for future partnerships that will continue to promote these practices and create a cleaner, more sustainable brick-making industry.

Promoting cleaner bricks in the HKH region.

The training was organised under the framework of the Himalayan Resilience Enabling Action Programme (HI-REAP) funded by the UK Government’s Foreign, Commonwealth & Development Office (FCDO). Immediately after the training, we organised a national stakeholder dialogue with brick and tile manufacturers in India to address social challenges in India’s brick sector and training on internal fuel application for brick manufacturers in Nepal to reduce coal consumption.
