Kendrapara, A Place-Based Sandbox

Kendrapara, Odisha A Rainmatter Foundation Sandbox

Taking the Place thesis from idea to ground.

Rainmatter Foundation initiated the Kendrapara Sandbox in 2023, in collaboration with 17 partner organisations, anchored locally by Socratus Foundation with Nature's Club. Kendrapara was the proving site: a coastal delta caught between the Brahmani, Baitarani and Dhamra rivers (with Mahanadi distributaries, Birupa, Chitrotpala, bounding the district to the south), holding the Bhitarkanika mangroves on one side and the rising sea on the other. This is the story of what happened when systemic, place-based interventions met community ownership over two years.

Rainmatter's place-based operating principles

Our work at the Foundation has been guided by the core need of making places thriving for all beings to exist in harmony. Three principles shape every Sandbox:

Place-based. Incorporate the factors that define a place holistically, ecology, economy, culture, politics, not in isolation.
Visibilise the trade-offs. Make explicit the choices communities are already making, so that the alternate pathways become legible.
Make alternate pathways available. Surface, connect, and resource the options communities want to choose.

Why it matters: when people in a place make choices thinking holistically, the place becomes thriving for everyone.

Why Kendrapara

Four leverage points that made this the right place to begin.

From a Foundation point of view, identifying leverage points that can be used to build an implementation architecture is what makes a place-based approach travel. Kendrapara had four:

01 · Collectivised communities

120 Climate Champions already organised (primarily SHG members) through Enhancing Climate Resilience of India's Coastal Communities (ECRICC, UNDP) across 400 villages. A ready cadre beyond just state-enabled SHGs and FPOs.

02 · A local anchor in place

Nature's Club, a local NGO, already acting as a "place" anchor and operating with 17 partner organisations (WellLabs, Socratus Foundation, SELCO, Goonj, Odisha Forest & Environment Department, UNDP, Kendrapara District Administration, among others).

03 · Existing platforms to ride

Programmes already on ground that could be plugged into: ECRICC, Mangrove Pathotsav, Kendrapara@2036.

04 · Institutionalisation hooks

Political and government openings to scale through: District Convergence Action Plan (DCAP), Kendrapara Vikas Mela (ORMAS), BAGAPATIA DPR (NABARD), UNDP-ECRICC, Agriculture Department's Crop Diversification Programme, and OSDMA.

About the place

A delta between three rivers, holding a forest against the sea.

Kendrapara is a coastal delta district shaped by the Brahmani, Baitarani, and Dhamra rivers, with Mahanadi distributaries, Birupa and Chitrotpala, bounding it to the south. It holds the Bhitarkanika mangrove ecosystem, one of India's most cyclone- and salinity-vulnerable geographies, and is overwhelmingly rural, informal, and agrarian, paddy, pulses, fisheries.

By area, Kendrapara is the centre of mangrove India in Odisha. The latest forest reports place ~212 sq km of mangrove cover inside the district, roughly 81% of the 259 sq km across Odisha's five coastal districts (Kendrapara, Jagatsinghpur, Puri, Bhadrak, Balasore). Nested around it sit the Bhitarkanika Ramsar wetland (~650 sq km) and the Wildlife Sanctuary (672 sq km, with a 145 sq km National Park core). Over the past four years, Kendrapara's mangrove cover grew by ~9.43 sq km, out of ~9.89 sq km for all of Odisha. Nearly every hectare the state added, it added here, largely through the fishbone-channel restoration model and CAMPA-funded work.

Job-linked migration is a defining feature. Kendrapara is often called the plumber capital of India, its men leave for cities and, increasingly, for the Middle East. Behind them, women hold the land. The district carries a rich political past as Biju Patnaik's constituency, and has long been a focus of Odisha's coastal resilience programmes, pond rejuvenation, mangrove restoration, women-led adaptation.

The Sandbox set out to test a single question: can Kendrapara become a model for ecosystem-based rural resilience, blending conservation, livelihoods, and community leadership into something that holds?

Identifying the problems

Before intervention, listening.

The first move was not a programme, it was deep sensemaking. Goonj's Gram Swabhimaan approach was deployed in a DIY format, with the process handed to community representatives who recontextualised it for Kendrapara. The question shifted from "What is wrong here?" to "What is happening here, really?"

Ecological degradation

Repeated cyclones, saline intrusion, and erosion eating the coast and the land it holds.

Livelihood insecurity

Traditional agriculture and fishing turning unviable, driving seasonal and distress migration. Kendrapara now exports plumbers to the Middle East.

Cultural disconnection

Mangroves and water bodies, once integral to local identity, were now being read primarily as threats.

Institutional fragmentation

Multiple government schemes existed, but with limited local convergence and no clear ownership at the village level.

"Start with listening. Real insight comes from community sensemaking."

Kendrapara Sandbox · Lessons

The method · Gram Swabhimaan

How we listened, turning a question into a worksheet.

Listening was operationalised. Goonj's Gram Swabhimaan template was adapted into a DIY worksheet handed to Climate Champions, who profiled each village across eleven dimensions of life. The deep diagnostic ran across 43 villages in two coastal blocks, Bhitarkanika and Mahakalpada, while lighter engagement (events, peer networks, producer-group convening) reached the wider 205 across nine blocks. Each dimension produced not a number, but a story.

01 · Census

Households

Number of households per habitation, the unit on which every downstream calculation rests.

02 · Income

Livelihood

Rice, fishing, daily wage, migration, mushroom, vegetables, what people actually do for money.

03 · Endowment

Assets

Ponds, tubewells, bamboo, Nalia grass, date palm, the natural and built capital a village can draw from.

04 · Lifeline

Water status

Saline vs. non-saline tables, drinking-source distance, rejuvenation needs for canals and ponds.

05 · Friction

Human–animal conflict

Crocodile encounters, wild boar, monkeys, abandoned bulls, what's threatening crops and bodies.

06 · Crop

Agriculture

Rice, pulses, vegetables, what grows, what fails, what's already been tried.

07 · Stock

Livestock

Cattle, goats, poultry, ducks, who keeps what, and for whom.

08 · Drain

Migration

Who leaves, where to, for how long, doing what. Kendrapara's "plumber capital" data lives here.

09 · Skill

Skill training

What training has reached the village, what's still missing, what people would attend tomorrow.

10 · Market

Value-chain opportunities

Where the village already produces something a buyer might want, the seed of any livelihood plug-in.

11 · Other

Anything we missed

An open field. The most important one, where surprise enters the dataset.

"The worksheet was not a survey. It was a way for a village to describe itself to itself, and to anyone who arrived later."

Climate Champions Cohort · Kendrapara

Community ownership

People as architects, not participants.

Saline-Resistant Rice farmers group

Women Climate Champions

Over 300 women across Odisha, 120 in Kendrapara, were trained as Climate Champions under the ECRICC programme (UNDP, March 2025), through a 30-hour curriculum delivered as three one-day workshops. They adopted resilient farming practices, led mangrove replantation drives, and passed knowledge through peer networks. The unit of change became the woman, not the project.

Alongside the Champions, 20 local Mentopreneurs were trained to support producer groups on value chains, green entrepreneurship, and climate-resilient livelihoods. A Mentopreneur is a first-generation entrepreneur rooted in local realities, working with SHGs, producers, and community players, and acting as the first point of contact between solution providers and the response ecosystem for technology, innovation, and research.

Self-Help Groups & youth networks

SHGs, youth clubs, and panchayat representatives formed the operational nucleus, engaging in Citizen Juries, Climate Recipe exhibitions, and Gram Swabhimaan dialogues. Abstract consultations turned into tangible community voice mechanisms.

Cultural re-framing

The narrative around mangroves shifted from fear to friendship. Mangroves stopped being obstacles to be cleared and became allies, flood protection, honey, crab farms, identity.

Local institution building

Nature's Club, a Kendrapara-based NGO, evolved into the anchor institution, holding space for external collaborations while keeping the ecosystem locally governed. The orchestrator stayed inside the place.

Key actors & orchestrators

An ecosystem of partners, anchored locally.

The Sandbox worked because no single actor tried to own it. Grassroots stewards led; civil society held the scaffolding; government and global partners brought weight and finance; local media carried the story.

From listening to linkage

How a village's "we need" becomes a partner's "we'll do."

The four categories below are not categories invented for a report, they are the four questions the village itself was already asking, in its own words, on its own porches. The funnel only gives the questions a shape that government, civil society, and solution providers can also read. Nothing was filtered for sounding correct; everything was sorted for who could carry it.

Step 01

Discover

A demand surfaces, through Gram Swabhimaan, the Village Assessment Survey, the Climate Champions Cohort, or events like Mangrove Patha Utsav.

Step 02

Categorise

Sorted by who must act: Individual, Community, Collective, or District Administration. The category determines the path.

Step 03

Unpack

A single demand explodes into its components. "Mangrove plantation" becomes ten distinct units of work, each a separate brief.

Step 04

Link

Each component is matched to a solution provider, drawn from the GRE Network, Sandbox partners, line departments, or marked "to be onboarded."

The unit of portability is the component, not the programme.

Programmes do not travel; their components do. Once a demand is unpacked, each component becomes a self-contained plug-in, small enough to be lifted, replicated, or remixed by a neighbouring district without inheriting Kendrapara's particular weather or politics. The funnel produced 94 such plug-ins, split roughly evenly between two landscapes. A selection from each is below.

How a new district uses this: pick the plug-ins that match its landscape, source providers from the GRE Network or local equivalents, and run the demand-discovery worksheet to find which ones the village actually wants. The framework is the worksheet plus the funnel, the rest is local choice.

Brand architecture & market linkages

From producer groups to product lines that reach the market.

The cumulative on-ground progress across enterprise plug-ins is represented through two umbrella brands and a set of agritech and FPO market-linkage partnerships.

Funding context. Much of this work was enabled by the presence of Climate Champions, who were part of the UNDP–GCF ECRICC coastal resilience programme (~US$130M for 2019–2027, across 24 coastal ecosystems in 12 districts spanning Andhra Pradesh, Maharashtra, and Odisha) and were leveraged as an on-ground cadre for the various Sandbox initiatives.

Lessons & takeaways

Five things this place taught us.

Start with listening.

Real insight comes from community sensemaking, not from sector frameworks parachuted in. The diagnosis must belong to the place.

How → Train Climate Champions to run the 11-dimension Gram Swabhimaan worksheet as a guided conversation (not a survey); commit every entry to a shared master sheet so each village has a living description of itself, accessible to anyone who arrives later.

Shift the story.

Changing local narratives, mangrove as friend, not threat, builds intrinsic motivation. Behaviour follows belief, not incentive.

How → Stage cultural moments (Mangrove Patha Utsav, Climate Recipe exhibitions, citizen juries) that reframe the resource publicly; produce short films, reels, and local-media features so the new framing travels at the speed of WhatsApp, not the speed of a report.

Identify the anchor.

Facilitation models like Nature's Club ensure continuity across funding cycles. The orchestrator must live in the place.

How → Designate one locally-rooted organisation as the orchestrator; route partner contracts, payroll, and convening through it; give it decision rights, not just facilitation duties, so it can hold the place across funding cycles.

Design for emergence.

Iterative prototypes, Azolla, mushroom, Nalia, Agarbatti, enabled adaptive scaling. The portfolio grew because no single bet had to carry the place.

How → Run multiple plug-ins as parallel 6-month sprints, each with a defined kill-switch and a producer-group lead; double down on the two or three that take traction; prune the rest without ceremony and feed the learnings back to the master sheet.

Integrate institutionally.

Bottom-up innovation influenced formal systems, ECRICC, the District Administration, the Forest Department. Community work travels when government carries it.

How → Map each plug-in to a state scheme (CAMPA, MNREGA, GPDP, ECRICC, Mangrove Mitra) before it scales; co-brand pilot outcomes with the District Collector; convert pilot data into convergent action plans for the next budget cycle so the work travels on government rails.

Method appendix

The diagnostic kit, summarised.

For any team adopting this approach in a new place, what we used, how we sorted, and what every column on the master sheet means.

Column	Meaning	Allowed values
Landscape	Which of two reference landscapes the demand belongs to.	Coastal · Rural
Demand discovered	The community's framing, kept in their words wherever possible.	Free text (e.g., "Pond rejuvenation")
Category of demand	Which actor must lead, and therefore where the brief lands.	Individual · Community · Collective · District Administration
Source of demand	Which listening instrument surfaced it, for traceability.	Gram Swabhimaan · Village Assessment Survey · Climate Champions Cohort · Mangrove Patha Utsav · others
Components unpacked	The plug-in level, the actual units of work.	Numbered list (1, 2, 3 …)
Status	Where each component is in the linkage funnel.	Solution provider onboarded · To be onboarded
Source of solution provider	Which network the provider was drawn from.	GRE Network · Sandbox Partner

Climate Champion question framework. Each Climate Champion took the eleven-dimension worksheet back to her village and ran it as a guided conversation, not a survey. Open questions ("what changed about water this year?") replaced closed ones ("how many tubewells?"). Follow-up visits to specific households were the norm, not the exception. The full per-village question set lives in a separate working sheet, organised by panchayat and revisited each season.

Why split into landscapes. Coastal and Rural are not administrative units, they are ecological and economic ones. A demand that is central to a coastal village (mangrove honey) is irrelevant in the rural interior; a rural demand (pineapple aggregation) is meaningless on the salt-affected coast. Splitting the master sheet by landscape made the plug-in library portable across districts that share an ecology, not just a state.

Status as a live field. Every component is tagged "Solution Provider Onboarded" or "To be Onboarded / Scoped." The sheet is read as a portfolio dashboard, open threads are the work-in-progress, closed ones are case studies. Partners and the field team work off the same view.

Monitoring & evaluation principles. M&E for a place-based programme is itself place-based. Three rough principles guide the measurement architecture. (i) Rooted in communities: track the number, diversity, frequency, and degree of institutionalisation of community participation; (ii) Responses tracked across three axes: social, economic, and ecological, never one in isolation; (iii) Outcomes-as-expectation, not outputs-as-claim: current estimates are flagged as crude first-order numbers, refined as producer groups, Climate Champions, and Department records mature.

A note on figure precision. Where rupee values are quoted (₹19 Cr carbon flow, ₹400–800 Cr coastal protection), the underlying physical quantity comes from peer-reviewed literature; the rupee conversion uses 2024–25 market or shadow prices. These are indicative for planning purposes, not audited valuations. Before any carbon number is presented as bookable, the project would need to be registered under a recognised blue-carbon methodology, Verra VM0033, the Plan Vivo Standard, or an equivalent, and ground-truthed against on-site biomass and soil sampling.

A note on programme figures. The livelihood numbers in the metrics and balance-sheet sections are partner-reported cumulative reach as of early 2025. They include households that adopted a practice at least once during the Sandbox period; rates of sustained adoption are tracked separately by the producer groups and Climate Champions cohort and are not summarised here.
