Urban green space, such as parks, forests, green roofs, streams, and community gardens, provides critical ecosystem services. Green space also promotes physical activity, psychological well-being, and the general public health of urban residents. This paper reviews the Anglo-American literature on urban green space, especially parks, and compares efforts to green US and Chinese cities. Most studies reveal that the distribution of such space often disproportionately benefits predominantly White and more affluent communities.

In 1997, the global value of ecosystem services was estimated to average $33. trillion/yr in 1995 $US ($46. trillion/yr in 2007 $US). In this paper, we provide an updated estimate based on updated unit ecosystem service values and land use change estimates between 1997 and 2011. We also address some of the critiques of the 1997 paper. Using the same methods as in the 1997 paper but with updated data, the estimate for the total global ecosystem services in 2011 is $125. trillion/yr (assuming updated unit values and changes to biome areas) and $145.

All crops require nitrogen (N) for the production of a photosynthetically active canopy, whose functionality will strongly influence yield. Cereal crops also require N for storage proteins in the grain, an important quality attribute. Optimal efficiency is achieved by the controlled remobilization of canopy-N to the developing grain during crop maturation. Whilst N will always be required for crop production, targeting efficient capture and use will optimise consumption of this valuable macronutrient.

Recent research and professional interest in planning for sustainable and resilient cities emphasizes the assessment of a broad spectrum of urban ecosystem services. While such assessments are useful to establish specific benchmarks, and for measuring progress toward sustainability and resilience goals, they do not motivate, or support the innovations required to provide specific ecosystem services as an intentional part of routine urban and infrastructure development activity by municipalities and professionals.

The economic crises seems blinding the governments and major economic actors toward environmental troubles. Nevertheless, the impacts of population growth and economic expansion have now the potential to disrupt important regulatory functions of global ecological systems. Green growth involves transforming the production and consumption processes in order to maintain or restore these regulatory functions of the planet's natural capital. It requires that environmental facto rs be treated as an essential factor of production and not merely an externality.
