The Asia-Pacific region contains almost half of the planet’s coastal carbon-sequestering (blue carbon) environments (mangroves, salt marshes, seagrasses). These habitats are highly valuable to sequester carbon and mitigate climate change, but are under threat throughout the region, due in significant part to an insufficient policy environment to protect, restore, or create new coastal wetlands/blue carbon environments. Using a systematic evidence synthesis we reviewed the existing literature on blue carbon policy, and found that gaps and challenges fall under three themes, “Land Tenure and Ownership”, “Funding and Protecting Blue Carbon Habitat”, and “Conflicting Priorities and Jurisdictions”, with two overarching issues, the inconsistent recognition of rights of indigenous peoples and local communities (IPLCs) and women, and sea-level rise. This study makes recommendations to ensure high-quality blue carbon projects through improving equitable outcomes, particularly for women and IPLCs, and to reduce barriers to implementing blue carbon projects. These recommendations include gender sensitive and participatory mapping along with a registry of ownership with extensive gender equitable IPLC consultation to resolve ownership uncertainties. Recommendations for community level and gender equitable benefits beyond individual land owners are important to address the inequity of land ownership. Where land ownership changes under sea-level rise and intentional barrier removal, carbon rights should be retained by the landowner; otherwise, there is little incentive to undertake blue carbon projects. Due to the limited income that results from some carbon credit payments, other crediting and non-market methods can be considered to supplement landowners’ incomes and encourage habitat protection. Conflicting priorities between authorities responsible for managing coastal wetlands can be resolved through systematic restructuring/streamlining and collaborative workshops. Some will require changes to policies and amending delegated legislation.

The meniscus is a meniscus-shaped fibrocartilage tissue located between the femur and tibia，it is mainly composed of meniscus cells and related extracellular matrix.The synovial limbus area of the knee joint capsule near the meniscus is divided into red areas with rich blood vessels and white areas with less blood supply according to the distribution of blood vessels,there is a transition zone called the red and white zone between the two;Red zone has better self-repair ability,The injury in this area can be treated by conservative treatment or surgical suture;Once the white area of the meniscus is torn and involves the free edge area,It is often necessary to partially remove the damaged meniscus.When most of the entire meniscus is severely torn and involved,not only the course of the disease is very long, but it cannot be repaired by sutures,Often a subtotal or total meniscus resection is required,whether it is a partial meniscus resection, a subtotal meniscus resection or a complete resection.In the later period, it may cause quadriceps atrophy and osteoarthritis (OA）.OA is a refractory multi-system disease,involve the patient’s peripheral joints,it has high disability and teratogenicity, and is very harmful to human health.Chondrocyte pyrolysis, degradation, and inflammation play a vital role in the destruction of OA articular cartilage and chondrocyte apoptosis.Meniscus stem cells have strong proliferation and differentiation ability,has become one of the hot spots in the field of meniscus repair,this article studies the role of meniscal stem cells in the development of OA.
