VULNERABLE (VU): A species considered to be facing a high risk of extinction in the wild. The specific criteria for each category are based on factors such as the number of mature individuals globally and the geographic range of the species Positive Human Roles in Ecosystems 2. Sustainable Practices: Sustainable Agriculture: Practices that minimize environmental impact, such as crop rotation, organic farming, and agroforestry. Sustainable Fishing: Fishing methods that prevent overfishing and protect marine life. Renewable Energy: Using solar, wind, and other renewable energy sources to reduce reliance on fossil fuels. Transforming Lives, Positive Human Roles in Ecosystems 3. RESEARCH AND EDUCATION: Environmental Research: Studying ecosystems to understand their functions and the impact of human activities. Environmental Education: Raising awareness about environmental issues and promoting sustainable behaviors. Transforming Lives, Negative Human Roles in Ecosystems 1. HABITAT DESTRUCTION: Deforestation: Clearing forests for agriculture, urban development, and logging. Urbanization: Expanding cities and infrastructure that fragment and degrade natural habitats. Wetland Drainage: Converting wetlands for agriculture or development, leading to loss of biodiversity. Transforming Lives, Negative 2.

INVASIVE SPECIES: Introduction of Non-native Species: Introducing species that outcompete or prey on native species, disrupting ecosystem balance. Invasive species is a non-native organism that significantly modifies or disrupts the ecosystems it colonizes. It can cause ecological, environmental, and/or economic damage. Invasive species can be introduced through natural migration or human activities Transforming Lives, HUMAN-ECOSYSTEM 1.

Despite its urban density, the city has made significant strides in implementing green initiatives to enhance its ecosystem. This case study explores Tokyo’s efforts in promoting sustainability through green roofs and walls, urban parks, and river restoration projects. Background Tokyo’s rapid urbanization has led to challenges such as the urban heat island effect, air pollution, and limited recreational spaces. To address these issues, the Tokyo Metropolitan Government has introduced various green initiatives aimed at creating a more sustainable and livable city. Green Initiatives 1.Green Roofs and Walls 1. Implementation: Tokyo has encouraged the installation of green roofs and walls on buildings throughout the city. These installations involve growing vegetation on rooftops and building facades. 2. Benefits: Green roofs and walls help reduce the urban heat island effect by cooling the surrounding air. They also improve air quality by absorbing pollutants and provide insulation, reducing energy consumption for heating and cooling. 2.Urban Parks 1. Development: The city has developed numerous urban parks, such as Yoyogi Park and Ueno Park, which offer green spaces for residents and visitors. 2. Benefits: Urban parks provide recreational spaces, promote physical activity, and serve as habitats for various species. They also contribute to the overall aesthetic and environmental quality of the city. 3.River Restoration Projects 1. Initiatives: Tokyo has undertaken river restoration projects, such as the restoration of the Sumida River and the Kanda River. These projects involve cleaning and revitalizing river ecosystems. 2. Benefits: River restoration helps improve water quality, supports biodiversity, and provides scenic areas for leisure activities. It also enhances flood control and resilience against natural disasters. Impact and Outcomes Tokyo’s green initiatives have yielded positive outcomes, including: Mitigation of Urban Heat Island Effect: The increased greenery helps lower temperatures in urban areas, making the city more comfortable during hot weather. Improved Air Quality: Vegetation absorbs pollutants, leading to cleaner air and better health outcomes for residents. Enhanced Quality of Life: The availability of green spaces and recreational areas contributes to the well-being and happiness of Tokyo’s inhabitants. Conclusion 27 Tokyo’s commitment to sustainability through green initiatives demonstrates how urban areas can balance development with environmental
