The work aimed to understand the current status of ecotourism and the potential of introduction of mangrove ecotourism in...

Global freshwater scarcity is projected to be affecting almost half of the world’s population by 2025. Desalination has become a reliable option to provide freshwater, especially with climate change and its direct impact on water resources. The desalination technology transforms some non-traditional water sources either by processing brackish water...

This chapter reviews recent developments in microplastic-related research; identifies major sources of microplastics to wastewater treatment plants (WWTPs); investigates the detection methods, concentration levels, and removal efficiency of microplastics at selected WWTPs; and presents a discussion on microplastics removal from wastewater and...

Key messages There is a need for a broader and holistic effort to address a host of environmental issues and challenges faced by the Tonle Sap Lake (TSL). In order to realize a sustainable and resilient TSL and its basin, this policy guide suggests three resilience enhancement measures: i) Ecohydrological resilience enhancement measures, ii) Land...

This comprehensive report was produced under the responsibility of the Ministry of Ecological Transition, Government of Italy, with the support of the Ministry of...

Plastic is ubiquitous: we use it for life-saving medical devices, clothing, toys and cosmetics; we use it in agriculture and industry. But we also know the growing risk of plastic waste in the environment, landfills and the oceans. For example, the amount of plastic that some fulmars accumulate in their stomachs during their lives is equivalent to...

プラスチックの生産と消費パターンの拡大、とりわけ使い捨てプラスチックや不適切なプラスチック廃棄物の処理に伴い、海洋生態系でのプラスチック廃棄物の蓄積が急増している。海洋のプラスチック汚染の主たる原因（海洋ゴミの約80％）は陸上から海へ流出するプラスチックである事が知られており、海洋のプラスチック汚染は世界的な関心を集める課題となって多くの政府や自治体が対応策を模索している。 より環境にやさしく持続可能なプラスチックの生産と消費を行う社会を実現するには、様々な利害関係者の参加と監視・評価に基づく長期的な取り組みが必要である。その第一ステップとして本レポートは、利害関係者の参加を促進し、国の廃棄物処理方針に沿った廃プラスチックを抑制する包括的な計画の開発を提言する。そのため、IGES-CCET...

Eight of the world's top 20 countries as sources of marine debris are from Asia—China, Indonesia, the Philippines, Vietnam, Sri Lanka, Thailand, Malaysia, and India (Jambeck et al., 2015). In other words, the Asia-Pacific region is now recognized as a hotspot of plastic pollution of the oceans. These countries are facing typical challenges...

Accumulation of plastic wastes in the marine eco-system is growing rapidly with the increase of plastic production and consumption patterns, particularly single-use plastics as well as unsustainable plastic waste management practices. Land-based sources are recognised as the main cause (up to 80% of total marine debris) of marine plastic pollution...
