Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. In 2008, urban population exceeded the rural population. In 2050, 70% of the world population will live in urban centers. The number of megacities (10 million inhabitants) increased from three in 1975 to 19 in 2007, and is projected to be 27 in 2025. Rapid urbanization is altering the ecosystem C budget. Yet, urban ecosystems have a large C sink capacity in soils and biota. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.

Even as they increase the beauty of our surroundings, trees provide us with a great many ecosystem services, incl. air quality improvement, energy conservation, stormwater interception, and carbon dioxide reduction. These benefits must be weighed against the costs of maintaining trees, including planting, pruning, irrigation, admin., pest control, liability, cleanup, and removal. This report presents benefits and costs for representative small, medium, and large trees in the Tropical region based on research carried out in Honolulu, Hawaii. Average annual net benefits increase with tree size and differ based on location:. Two hypothetical examples of planting projects are described to illustrate how the data in this guide can be adapted to local uses.

Fully updated and greatly enhanced, the Third Edition of Urban Forestry addresses current issues in planning, establishing, and managing trees, forests, and other elements of nature in urban and community ecosystems. The authors discuss why we have trees in cities and how we use them, clarify the appraisal and inventory of urban vegetation, and extensively delve into the planning and management of public as well as private vegetation. As urban forestry continues to evolve as a profession, foresters and arborists can expect many challenges as well as opportunities. The continuing development of cities has become linked to a much greater emphasis on urban vegetation, the growing demand for recreation amenities within the urban environment, and the careful and successful management of vegetation in an urban ecosystem. New ways to incorporate the highly versatile urban forest resource into the urban fabric will undoubtedly benefit the lives of its residents.

The Million Trees LA initiative intends to chart a course for sustainable growth through planting and stewardship of trees. This study measures LA's existing tree canopy cover (TCC), determines if space exists for 1 million additional trees, and estimates future benefits from the planting. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. LA's existing TCC was 21%. There is potential to add 2.5 million additional trees to the existing population of 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Thus, there is space for planting 1 million new trees. Benefits for the 1-million-tree planting were between $1.33 band $1.95 billion.
