This building block focuses on restoring and maintaining natural mineral licks to enhance the availability of essential nutrients such as sodium, calcium, and magnesium for wild animals. Over time, mineral licks can degrade due to erosion, invasive species, sedimentation, or human disturbance. Management activities include removing invasive vegetation, reshaping the lick, stabilizing soil using natural materials, and maintaining low-disturbance zones.
Community involvement is key: they help identify degraded lick sites, report disturbances, assist in restoration, and prevent livestock from entering lick areas. Their participation improves protection, strengthens ownership, and ensures long-term sustainability.
Healthy mineral licks improve wildlife nutrition, reproductive success, bone development, and overall health. When integrated with waterhole and grassland management, mineral lick restoration provides a comprehensive habitat improvement strategy.

This building block restores and maintains grasslands through selective clearing of invasive species, controlled burning (where appropriate), and sowing of palatable native grasses. Grasslands improve natural forage availability, support herbivore populations, and reduce human–wildlife conflict.
Community members contribute by helping with clearing, seed collection, and monitoring regrowth. Their participation improves ownership, reduces accidental fires, and strengthens local stewardship.
Restored grasslands reduce pressure on agricultural lands, enhance wildlife distribution, and create healthier ecosystems that complement patrolling, waterhole restoration, and mineral lick management.

This is to revive, preserve, and apply Indigenous and local knowledge systems that have historically supported the sustainable use and conservation of biodiversity in and around the cascade ecosystem. These knowledge systems have deeply rooted in centuries of interaction with ecosystems, offering practical, time-tested methods for managing natural resources in ways that maintain ecological balance. By integrating this knowledge with modern conservation science, biodiversity efforts become more culturally respectful, inclusive, and effective. Sri Lanka: The tank cascade systems (Elangawa) are ancient water management practices that support aquatic biodiversity and rice cultivation in dry zones. 

• Village elders and traditional irrigation managers (Vel Vidane) knew when to open and close sluice gates based on the timing and pattern of monsoon rains, not fixed calendars. They rely on subtle signs such as the first call of migratory birds, flowering of trees, or moisture in soil layers to make water release decisions—practices rooted in observation, not engineering manuals.
• Farmers traditionally maintain vegetated buffer zones (Kattakaduwa) at the downstream edge of the tank to filter salts, protect water quality, and maintain soil health. This practice was not scientifically explained in the past, but local communities knew that removing these vegetated zones harmed crops and water quality.
• Local farmers have an intuitive sense of where sediment settles, how to periodically dredge, and how to reuse silt to improve soil fertility. Such practices have helped sustain tanks over centuries without formal hydrological models.
• Communities understand the presence of birds, fish, and reptiles in and around tanks as part of the ecosystem's health—some even avoid disturbing nesting areas or harvest fish only after spawning periods, even in absence of formal rules.

They will invest on that, like I said, smarter in general, zero pollution as project as fast as we can.

While Sparśa in Nepal serves as a pilot enterprise, NIDISI’s ambition reaches far beyond one country. Years of networking with practitioners, academics, social entrepreneurs, and NGOs showed us that many projects across the Global South are working with natural fibres — banana, sisal, water hyacinth, bamboo — yet most face similar challenges: how to process fibres efficiently, ensure product quality, secure market access, and build financially sustainable social businesses. To address this, we launched the Sparśa Blueprint Project, which creates a global community of knowledge sharing for compostable pad manufacturing.

The Blueprint is where Sparśa’s technical expertise, R&D, and social business lessons are opened up for replication. It documents machinery CAD files, sourcing strategies, financial planning models, and outreach approaches, but also creates space for dialogue and co-creation. Connecting projects across the globe enables local innovators to learn from each other and adapt the model to their own contexts and fibre plants.

First building block of Journey of Community Building: Creating a Globally Adaptable Blueprint Model for Fibre Pad Manufacturing — will be published on the PANORAMA platform in September 2025, and a full solution page will follow in November 2025. There, we will share the accumulated experience of years of building networks across continents, including insights from collaborations with grassroots entrepreneurs, academic partners such as Stanford University’s Prakash Lab and LGP2 from the Grenoble INP-Pagora, NGOs, and local governments. This scaling of our project will serve as the gateway for replication, helping others create their own fibre-based pad enterprises.

Product development does not end with certification. To create menstrual pads that are accepted, trusted, and widely adopted, Sparśa built a structured system to integrate real user experiences into design improvements.

This building block focuses on user feedback surveys and community-based testing of Sparśa pads. The initial questionnaire was co-designed by the team and adapted from international tools, but simplified after field trials revealed that long, technical questions discouraged participation. The refined survey is short, available in both Nepali and English, and structured around everyday experiences of menstruation.

The survey collects both quantitative data (absorbency, leakage, comfort, ease of movement, wearability) and qualitative insights (likes, dislikes, suggestions). It also includes questions about packaging, clarity of information, and first impressions. Importantly, the survey is distributed through Google Forms for easy access and rapid data analysis, but also adapted for offline use where internet is unavailable.

The next stage is scaling up to at least 300 users, ensuring diverse representation across age, geography, and socioeconomic background. By triangulating lab results (Block 3) with user feedback, Sparśa can continuously optimize pad design, packaging, and distribution strategies.

This approach demonstrates that menstrual product development is not only about technical performance, but also about cultural acceptability, dignity, and user trust.

This building block captures the iterative process of translating user insights into tangible menstrual pad prototypes. Guided by the national field research (Building Block 1), Sparśa developed and tested multiple pad designs to balance absorbency, retention, comfort, hygiene, and compostability.

The process took place in two phases:

Phase 1 – Manual prototyping (pre-factory):
Before the factory was operational, pads were manually assembled to explore different material combinations and layering systems. Prototypes tested 3–5 layers, usually including a soft top sheet, transfer layer, absorbent core, biobased SAP (super absorbent polymer), and a compostable back sheet. Materials such as non-woven viscose, non-woven cotton, banana fibre, CMC (carboxymethyl cellulose), guar gum, sodium alginate, banana paper, biodegradable films, and glue were evaluated.

Key findings showed that while achieving high total absorbency was relatively easy — Sparśa pads even outperformed some conventional pads in total immersion tests — the main challenge lay in retention under pressure. Conventional pads use plastic hydrophobic topsheets that allow one-way fluid flow. Compostable alternatives like viscose or cotton are hydrophilic, risking surface wetness. Prototyping revealed the need to accelerate liquid transfer into the core to keep the top layer comfortable and dry.

Phase 2 – Machine-based prototyping (factory):
Once machinery was installed, a new round of prototyping began. Manual results provided guidance but could not be replicated exactly, as machine-made pads follow different assembly processes. Techniques such as embossing, ultrasonic sealing, and precise glue application were tested, alongside strict bioburden control protocols in the fibre factory.

Machine-made prototypes were systematically tested for absorption, retention, and bacterial counts. Internal testing protocols were developed in-house and then verified through certified laboratories. Initial results showed that bacterial loads varied significantly depending on fibre processing steps (e.g. cooking or beating order), underlining the importance of strict hygiene control.

Iterative design cycles combined laboratory testing with user comfort feedback, allowing continuous adjustments. By gradually refining layer combinations, thickness, and bonding methods, Sparśa optimized the balance between performance, hygiene, and environmental sustainability.

Annexes include PDFs with detailed prototype designs, retention test data, and bacterial count results. These resources are provided for practitioners who wish to replicate or adapt the methodology.

Wewalkele is one of the pilot ESAs, is home to several threatened animal species such as the Thambalaya (Labeo lankae), the Leopard (Panthera pardus), the Fishing cat (Prionailurus vi-verrinus), the Elephant (Elephas maximus), and the Eurasian otter (Lutra lutra). Amidst the 125 flora species identified, cane plants grow to be quite tall and dense, are usually located in mud-dy groves, and are extremely thorny. People from the surrounding villages harvest Heen Wewal (Calamus) from Wewelkele using unsustainable means to make handicraft items that often sup-plement their household incomes. Recognizing the role played by the Wewalkele area in biodi-versity and sustenance of ecosystem services, and its potential threats, Divisional Secretariat (DS) and the community members joined hands to safeguard it via the respective Local Management Committee (LMC) in 2018, defining Wewalkele Co-Management Plan. The area was surveyed both socially and physically, demarcated to avoid further encroachment to ensure its conservation targets are met. And, to leave no one behind, the project focused on incentivizing the surrounding community to conserve the ESA while sustaining the economic benefits derived from it by transforming their existing natural resource usage to green jobs by enhancing their skills, facilitating stable market linkages and ultimately promoting the cane industry further. To ensure the sustainability of the community livelihoods, the project also worked towards setting up cane nurseries along with the required replanting facilities and support the village craftsmen to develop craftsmanship on value added products and to link them with marketing networks. The strong partnership with the local government bodies the community and oversight of LMC was the secret to the success of the managing ESA. Communities, natural habitats and biodiversity can co-exist, benefit each other, be protected and thrive, and the Wewalkelaya ESA is evi-dence of that!

In 2028, two further surveys are to be carried out in the stream where the crayfish were released to determine whether the release campaigns of 2024-2026 were successful and a stable population of crayfish was able to establish itself in the stream.
