Restauration des mangroves par les communautés locales

Restauration des mangroves par les communautés locales

Dans le cadre d’un projet mené en 2017 par le Service Territorial de l’Environnement (STE) de Wallis et Futuna, avec le soutien financier du programme européen BEST 2.0, 2.5 hectares de mangroves ont été replantés. Le projet a impliqué les scolaires, les associations et les villages. Il a consisté à la construction de 6 pépinières dans différents villages de l’île par des associations, qui ont pu être accompagnées techniquement et financièrement.
Les associations locales ont été essentielles à la réalisation des principales activités. La Direction de l’Education Catholique (DEC) a également été l’une des principales parties prenantes concernant le volet sensibilisation. En effet, une étroite collaboration s’est nouée entre le STE et la DEC se traduisant par la réalisation d’un grand nombre de sorties scolaires et la réalisation de plantations par les élèves des écoles primaires. La chefferie est également une entité importante du projet, son aval étant indispensable pour réaliser ces actions.

From Fields to Forests: Integrating Nature into Kharagpur’s Agriscapes

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.

Ciudades Resilientes: Área Protegida Urbana de la Universidad de Buenos Aires

Durante los años 60 se desarrollaron muchos vertederos en el Río de la Plata, Argentina. Estas acciones crearon un nuevo ecosistema de origen antropogénico.

En 1985, un movimiento estudiantil comenzó a trabajar para proteger este sitio que se conocía como La Reserva Biológica y Parque para la Difusión de la Ciencia.

La reserva fue el primer área urbana de Buenos Aires. Con el apoyo de las autoridades, comenzó un trabajo de tres décadas, y en 2011 el lugar fue designado por ley como un área urbana protegida llamada Ciudad Universitaria, Reserva Ecológica.

Este sitio juega un papel esencial en la universidad y la ciudad de Buenos Aires, brindando servicios ambientales estratégicos para la salud humana. Es un excelente ejemplo de cómo los parques urbanos son esenciales para el bienestar de las personas que viven en las ciudades.

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.
