    Points of proposals

    1. Provisional Common Indicators

    Establish common indicators for basic elements. For the time being, leave them as provisional, due to the diverse conditions of

    the cities.

    2. Common Indicators, Different Weights

    Use scores as a yardstick for cities to understand their conditions.

    Each city determines the weighting of elements necessary for its overall

    assessment.

    The total scores among cities will not be compared because independent

    weighting of elements makes this meaningless.

    3.Additional Indicators for Development by Each City

    Each city shall add or develop indicators according to their respective

    conditions so as to complement the common indicators.

    4. Continuous Fine-tuning through Sharing of ExperienceTowards COP10

    Prepare Provisional Common Indicators based on the trial results of the

    Singapore Index tested in multiple cities

    At the City Biodiversity Summit to be held as an associated event to the COP10,

    appeal to the cities of the world for the use of Provisional Common Indicators

    and the development of Additional Indicators that reflect the actual conditions

    of each city.

    Towards COP11

    Exchange experiences (in the use of common indicators and the development

    of additional indicators) among various cities based on the appeal made above.

    Fine-tune the Common Indicators based on the experiences exchanged.

    Provide information that will assist cities in developing their Additional

    Indicators

    0. Indicators on Characteristics

    of the City

    The cities in the world are diverse. They have diverse natural environments

    and different social conditions.

    Urban ecosystems are impacted considerably by human activities. They are

    also affected to a great extent by climate, topography, geological condition, water

    system, etc. Simply deliberating upon whether the numbers of species are many orfew is meaningless. It is important to discern what a sound ecosystem means to that

    area.

    Urbanization condition, population growth rate, and the like are policy

    variables for a city. In reality, however, they have become the given conditions and

    constraints to many cities.

    The characteristics of the natural and social conditions of cities are moreeasily elucidated by comparing them among cities. Development of Indicators on

    the Characteristics of the City is proposed in order for cities to be able to assess

    their own biodiversity.

    A. Indicators on Biodiversity

    in the City

    Human activities have a strong influence on the urban ecosystems. However,

    city residents have many more neighbors than they realize that are making habitats

    and breeding in the cities, that is, wildlife.

    Among the wildlife that lives in cities, some can adapt to the artificial

    environments and some cannot. Those that cannot adapt are on the brink of local

    extinction. It is not only that the numbers of species that inhabit and breed and theirpopulations are in decline, but the original balance of the ecosystems has collapsed.

    However, urban ecosystems are not only declining. Improvements are also

    found: the improved river quality has restored fish species and along with that, birds

    have returned.

    What efforts are effective in restoring sound balance to the ecosystems in

    accordance with the condition of each city? Indicators on Biodiversity in the City

    are the starting point of the search for an answer.

    There is a wide array of habitats in the city. Which part of these habitats

    should have priority for conservation and which part should have priority for

    restoration? The answers vary depending on the condition of the city. Some cities

    may need not only indicators that evaluate the city in general but also indicators that

    evaluate the city in smaller units.

    While common indicators can serve as a start, it is hoped that every city will

    develop their own original indicators that can reflect the conditions of their own city.

    Additional Ind icators for Development by Each City

    * Biodiversity in a city is dependent not just on the area of natural and semi-natural land but also on the

    topography, geological condition, water system, and the diversity of the citys ecosystems/habitats sustained

    by such natural conditions..

    A wide range of high to low quality biotopes1)

    is the special attribute of a city.

    They are an invaluable natural asset to the city and are the starting point for cultivating biodiversity2)

    .

    1Brussels presentation (ICLEI World Congress, Edmonton, Jun. 2009)

    2) Montpelliers presentation (2ndCuritiba Meeting on city and biodiversity, Jan. 2010)

    Therefore, it is hoped that self-assessment (reevaluation of natural assets) will focus on the distribution of the

    ecosystems/habitats, irrespective of their sizes, and be carried out based on the actual conditions of the city.

    Additional Ind icators for Development by Each City

    * Anthropogenic green space, such as parks and gardens, accounts for a large percentage of vegetation in

    cities.

    It is important to not view such green space as having less ecological value than the natural and

    semi-natural areas but rather to try to bring the anthropogenic green space to a sound and sustainable

    condition as much as possible.

    Some cities may need to look at smaller units, such as distinction between urban areas and non-urban areas,

    to understand the actual situation.

    * The definition of protected area is not the same for all cities.

    The protection/regulation levels vary, ranging from protected areas that are required to maintain the current

    state to protected areas that allow certain usages.

    The variety of such flexible protection/regulation approaches is expected to increase in the future.

    Therefore, it is expected that cities devise their own indicators for areas officially secured for

    environmental conservation based on each citys condition while using the left as reference.

    * Because land use in a city is segmented into small units, it is not easy to calculate the average patch size for

    the natural and semi-natural areas.

    For this reason, only the average patch size of the protected areas/parks, etc. is considered here.

    There are cities that make efforts to reconnect fragmented habitats using corridors.

    It is expected that an indicator that can validate the outcomes of activities carried out by a city will be

    developed, rather than the one that considers only the average patch size.

    * Farmland is a precious habitat for a city and for the suburban areas of a city.

    The increase or decrease in the area of farmland and the quality of the farmland ecosystem are an important

    concern to a citys biodiversity.

    Additional Ind icators for Development by Each City

    * It may be beneficial for some cities to use smaller units to enable a better understanding of the situation and

    to identify the increase or decrease in the populations at hot spots, rather than measuring the city as a whole.

    This is because the total number of species in the city does not change within a short time.

    It is more meaningful to think of the total number of species in the city as an indicator that reflects the

    climate, geographical conditions, and other characteristics of the city rather than as an indicator of

    environmental changes.

    * Should the focus be on the number of native species or the number of total species?

    It is recommended that all the species (not distinguishing the good and the bad) be first identified, including

    the introduced species, escaped species, and then the conditions of the native species, alien species, invasive

    alien species, threatened species, and so on be analyzed.

    B. Indicators on Ecosystem Services

    in the City

    Cities of the twentieth century pursued freedom from nature. However, new

    problems have emerged to plague the cities. A decrease in the cities greenery has

    given rise to the heat island phenomenon and flooding problems specific to cities.

    Artificial bank protection has reduced the self-purification capacity of rivers. Climate

    change has continued to intensify natural disasters so much as to dwarf the

    infrastructure built to conquer nature.

    As the daily life of city residents becomes increasingly detached from nature,

    there are fewer opportunities to pass the wisdom of how to interact with nature (the

    wisdom of how to utilize the power of nature and how to avoid natural disasters) to

    our children. For the adults as well, the common space in the neighborhood for

    relaxation and the space that is the spiritual and cultural center of the community are

    decreasing.

    Against this backdrop, cities all over the world have begun to reevaluate the

    role of a great infrastructure called ecosystem and to pursue urban development

    that can effectively utilize its functions. This pursuit also helps to contain the

    financial burden of building artificial infrastructure.

    The Indicators on Ecosystem Services in the City are a means for city

    residents to gain a new recognition and to deepen understanding of natures blessings.

    Which ecosystem service shall have priority varies from city to city. It is desirable

    that each city develop indicators that can match its actual conditions.

    C. Indicators on Pressure

    on Ecosystems within the City

    Land-use changes, pollutant emissions, and other city activities put direct

    pressure on the living and breeding environments of living things.

    However, it is possible to improve these environments by making appropriate

    city designs and controlling emissions. For cities hard-pressed by population growth,

    it is necessary to distinguish between areas that need to maintain or increase capacity

    for accommodating the population and areas that need to limit changes to land use.

    What is the tipping point of the citys ecosystem? What will be effective in

    bringing out the potentials of urban ecosystems and securing the sustainability of

    ecosystem services? Indicators on Pressure on Ecosystems within the City are a

    means for finding an answer to these questions.

    The severity of the burdens and the key areas for improvement differ

    depending on the city. It is desirable to creatively develop original indicators inaccordance with the condition of each city.

    D. Indicators on Dependence

    on Ecosystems outside the City

    A city depends on the ecosystem services of other cities and other countries

    for its food and other necessities. However, the sustainability of the worlds

    ecosystem services that the cities depend on is called into serious doubt, as pointed

    out by the Millennium Ecosystem Assessment and the Global Biodiversity Outlook.

    To ensure the sustainability of the city, it is not sufficient to just conserve andrestore the ecosystems within the city. This is because city population has surpassed

    half of the worlds population and will increase to over 60% by 2030.

    The cities impact on production, distribution, and consumption, and their

    problem-solving capability supported by collaboration with the government, citizens,

    and businesses are a tremendous force to be reckoned with. It is necessary to utilize

    these attributes to help secure sustainability of the worlds ecosystem services.

    Indicators on Dependence on Ecosystems outside the Cityare the starting

    point of such activities. However, such an assessment method is still in development.

    It is desirable to have many cities using their creativity in facilitating this

    development.

    E. Indicators on Local Action

    In order to incorporate considerations for biodiversity into various policy

    areas and the daily activities of different social sectors, many countries have put in

    place a National Biodiversity Strategy and Action Plan.

    In recent years, local governments have also started to formulate Local

    Biodiversity Strategies and Action Plans. Many cities have been introducing a

    biodiversity viewpoint into their green space management, river management, or

    other plans even if they have not previously had any biodiversity strategy or action

    plan.

    In this section, indicators to evaluate such local action are proposed.

    The indicators mentioned here are merely starting points to be used for

    evaluating the process. They may fall short from the perspective of tackling citys

    specific priorities and concerns. It will be necessary to evaluate not only activities

    undertaken by government agencies but also self-initiatives carried out by citizens

    and businesses in the future.It is desirable that each city takes the above into consideration and develops

    indicators that are more practical and apt.
