SIREN: A Mobile App and Network of Fishermen to Save Marine Wildlife in Cameroon and Beyond

In Cameroon and other resource-limited countries, marine wildlide data relies heavily on anecdotal reports and one-off surveys, leading to substantial knowledge gaps that hinder effective conservation efforts. The scarcity of scientific expertise, combined with the high cost of dedicated boat surveys, presents a significant barrier to marine wildlife research and conservation.

Fishers and marine species share habitats and resources on a daily basis, creating potential for fishers to act as citizen scientists. We established a network of over 80 fishers who regularly report marine wildlife sightings using a Smartphone App, SIREN. This user-friendly app, compatible with Android and iOS, allows fishermen to document marine mega-fauna sightings, and to capture and upload up to four photographs, along with additional information such as a description. The App automatically associates a location and date with the report, providing data that can be used to co-design conservation measures.

The Sustainable Agriscapes for Future (SAF) project, led by IUCN and ITC, addresses ecosystem degradation in the Kharagpur Agriscape of Bihar, India through nature-based solutions. The Agriscape, reliant on forests and a lake, faces challenges such as deforestation, soil erosion, spread of invasive species, and unsustainable farming practices. Through spatial planning, the project delineated the Kharagpur Agriscape and developed Kharagpur Agriscape Plan aimed at conserving and enhancing natural ecosystems vital for supporting agriculture within the cluster. This included interventions such as women-led eco-nurseries, vermicomposting using using invasive water hyacinth, and community pastureland for fodder. These nature-based, community-centered solutions enhance soil health, reduce pressure on forests, and empower women and farmers. Capacity-building, alternative livelihoods, and improved ecosystem services underpin this replicable approach for sustainable rural development.

Promoting Satoumi Community Co-Management through Resilience Assessment: A Case Study of Chenglong Wetlands (Nantou, Taiwan)

Located along the western coast of Taiwan, Chenglong Wetlands was originally farmland. Since 1986, multiple typhoons have caused levee breaches and seawater intrusion, leading to farmland abandonment and its gradual transformation into grassy wetlands. Through joint efforts by the government, academia, civil groups, and local communities, the wetlands have been preserved as habitats, for water purification, and for disaster prevention. Environmental education and art have further revitalized community culture, creating a landscape that blends human and natural elements.
The Nantou Branch of the Forestry and Nature Conservation Agency introduced the concept of Socio-ecological Production Landscapes and Seascapes (SEPLS) and organized resilience assessment workshops (RAWs) centered on community residents. These workshops assessed environmental, economic, and social resilience, clarified key local issues, and explored ways for economic activity and ecological conservation to coexist, embodying the spirit of a Satoumi community.

Engineering the Production of Compostable Menstrual Pads Using Plant-Based Fiber as the Main Absorbent Core

This initiative is part of the Sparsa Solution, a Nepali non-profit organization that locally produces and distributes compostable menstrual pads, which have an absorbent core made from banana fiber.,
Conventional fluff pad production machines are either manual-making them labor-intensive and unhygienic-or fully automated, which requires high upfront investment and is often incompatible with eco-friendly materials. To overcome these challenges, engineers from NIDISI, Sparsa, and Grit Engineering developed a semi-automatic, low-cost system tailored to local Made in Nepal.
Built with limited resources, the system produces 3,500–4,000 pads per day and includes:

A paper shredder for uniform fiber cutting;
A custom mattress-making machine for the fluffy absorbent core;
A modified pad assembly machine that seals different layers using ultrasonic sealing and compostable glue.

This setup enables safe, small-scale production while reducing plastic waste and supporting menstrual health for the benefit of women and the environment.

Eco-Friendly Salt Marsh Restoration Using Fishery By-Products

IPCC recognizes seagrass beds, salt marshes, and mangroves as the three primary blue carbon ecosystems. Taean National Park features a diverse coastal environment including salt marshes, coastal sand dunes, and seagrass beds. These habitats support a variety of species that are specially adapted to these environments. These areas are ecologically significant both as critical habitats and natural carbon sinks. However, ongoing coastal development and increasing visitors have led to continuous degradation and a reduction in their area due to human activities.

In the past, fishery by-products were classified as general waste. Improper disposal practices, including illegal dumping and uncontrolled accumulation along the coast, resulted in marine pollution, foul odors and decay. To address this issue, legislation was enacted to promote the recycling of fishery by-products. In line with this initiative, the park launched a pilot project to restore salt marshes and reinforce the coastline using recycled oyster shells.

Swinging into action: French golf tees off for biodiversity conservation

To better understand and preserve the rich yet under-documented biodiversity of golf courses, the French Golf Federation partnered with the National Museum of Natural History in 2016 to launch the Golf for Biodiversity Programme. The initiative aims to improve ecological knowledge, management, and conservation practices on golf courses in France. When joining the Programme, an ecological diagnostic is conducted on the golf course by a naturalist organisation and clubs implement tailored action plans based on expert recommendations. A Bronze, Silver, or Gold certification rewards efforts to study, protect, and promote biodiversity, based on the club’s commitment level. Data collected feeds into the National Natural Heritage Inventory, advancing national scientific research. While the Museum gains valuable insights into previously overlooked ecosystems, clubs benefit from expert support, training, strong peer network, and enhanced image.

Conserving Critically Endangered rosewood and Endangered padauk species in Community forest Vietnam's Central Annamite

Rosewood (Dalbergia spp.) and Dipterocarpus macrocarpus are among the most logged and traded tropical timbers in Southeast Asia due to high demand from the luxury furniture market. Extensive illegal logging and trade have led to local extinction or severe population declines across its range. In response, we propose a community-based conservation program in the Central Annamites, Vietnam. The initiative includes establishing community nurseries, replanting rosewood in known habitats, and protecting remaining mature mother trees through the creation of Other Effective area-based Conservation Measures (OECMs) in community forests. This integrated approach will safeguard vital seed sources, support long-term species recovery, and actively engage local communities. In doing so, it will also create alternative income streams through seedling production, participation in restoration efforts, and access to carbon credits and other green financing opportunities.

The Nature Conservancy & National Geographic Society Externship Program

Together, the partners developed a program centered around a rigorous externship open to young adults ages 18-25 to equip them with the knowledge, tools, and relationships to seek solutions and take action in their communities around the globe. The program intentionally creates more opportunities for young people from all communities to prepare for careers in conservation and exploration. At the end of this eight-week experience, externs create an ArcGIS StoryMap presentation based on the local conservation issue they investigated. As the externship concludes, participants can apply for seed funding to begin enacting the solutions they identified in their communities. The program has addressed the challenge of inadequate leadership opportunities for global youth, by providing young adults from ages 18-25 with the opportunity to tackle global conservation issues, while gaining conservation skills.
