(1997), six are considered to have a major importance in urban areas: air filtering (gas regulation), micro-climate regulation, noise reduction (disturbance regulation), rainwater drainage (water regulation), sewage treatment (waste treatment), and recreational/cultural values.
What is ecosystem services PDF?
Ecosystem services are the benefits provided to humans through the transformations of resources (or environmental assets, including land, water, vegetation and atmosphere) into a flow of essential goods and services e.g. clean air, water, and food (Constanza et al. 1997).
What are the main goals of CBD?
It has 3 main objectives: The conservation of biological diversity. The sustainable use of the components of biological diversity. The fair and equitable sharing of the benefits arising out of the utilization of genetic resources.
What is definition of biodiversity in CBD?

The Millennium Ecosystem Assessment (MA), a major UN-sponsored effort to analyze the impact of human actions on ecosystems and human well-being, identified four major categories of ecosystem services: provisioning, regulating, cultural and supporting services.
Why urban ecosystem services are important?
Ecosystem services are of especial significance in cities, mainly through regulating services that affect water quality, stormwater, flood and erosion control, waste disposal and air quality, and cultural services such as recreation, health and well-being, and contributing to a sense of place.
How many urban ecosystem services are present?
We identify seven different urban ecosystems which we call natural, even if almost all areas in cities are manipulated and managed by man. The ecosystems are street trees, lawns/parks, urban forests, cultivated land, wetlands, lakes/sea, and streams.
What are the 7 main ecosystem services?
The benefits ecosystems provide include food, water, timber, air purification, soil formation and pollination. But human activities are destroying biodiversity and altering the capacity of healthy ecosystems to deliver this wide range of goods and services.
What is the importance of ecosystem services?
Ecosystem services make human life possible by, for example, providing nutritious food and clean water, regulating disease and climate, supporting the pollination of crops and soil formation, and providing recreational, cultural and spiritual benefits.
What are the 3 main objectives of biodiversity conservation?

What are the 3 main goals of the Convention on Biological Diversity?

Ecosystem services are all the processes and outputs that nature provides us with. These include provisioning services (food, water), regulating services (waste water treatment, pollution control), supporting services (shelter), and cultural services (recreation and tourism).
Why was the concept of urban ecosystem services developed?
We conclude that the use of the concept of urban ecosystem services can play a critical role in reconnecting cities to the biosphere, and reducing the ecological footprint and ecological debt of cities while enhancing resilience, health, and quality of life of their inhabitants.
What is the difference between urban ecosystem and natural ecosystem?
A. Definition
Unlike natural ecosystems however, urban ecosystems are a hybrid of natural and man-made elements whose interactions are affected not only by the natural environment, but also culture, personal behaviour, politics, economics and social organisation.
What is urban ecosystem and example?
(2001), urban ecosystems are those where people live in high densities or those where the built infrastructure covers a large proportion of the land. The infrastructures in these areas incorporate both planted vegetation such as urban forests, parks and gardens and water bodies like ponds, small lakes and wetlands.

What are the types of ecosystem services?
Ecosystem services are classified into four types:
- Provisioning Services. This includes the products/raw materials or energy outputs like food, water, medicines and other resources from ecosystems.
- Regulating Services. This includes the services which regulate the ecological balance.
- Supporting services.
- Cultural services.
