  • borealW - northern; cold temperate Northern Hemisphere forests that grow where there is a mean annual temperature < 0°C.

  • bottom up approach - the piecing together of systems to give rise to grander systems, thus making the original systems sub-systems of the emergent system. Bottom-up processing is a type of information processing based on incoming data from the environment to form a perception. This strategy often resembles a "seed" model, whereby the beginnings are small but eventually grow in complexity and completeness. However, "organic strategies" may result in a tangle of elements and subsystems, developed in isolation and subject to local optimization as opposed to meeting a global purpose. Contrast with a top down approach.

  • Brundtland Commission Report - a UN report, Our Common Future, published in 1987 and dealing with sustainable development and the policies required to achieve it, which the report characterizes as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

  • buswayW - high-capacity bus transit systems. These became the poster child of affordable, efficient and sustainable public transport systems thanks to the success of Curitiba transportation. This has been emulated elsewhere, with varying degrees of success. The system in Jakarta has been plagued with problems, notably a greatly delayed rollout and inadequate capacity, resulting in delays and crowding. The design of the bus stations raises safety concerns, especially at many bus stops where passengers wait at open doors above the busy roadway, with no safety barrier.

C3 plants, the other 95%, photosynthesise to form 3 carbon molecules and increase photosynthesis with as CO2 levels increase.
  • calorieW – a basic measure of energy that has been replaced by the SI unit the joule; in physics it approximates the energy needed to increase the temperature of 1 gram of water by 1 °C which is about 4.184 joules.

There are two forms of carbon credit, those that are part of national and international trade and those that are purchased by individuals. Internationally, to achieve Kyoto Protocol objectives, 'caps' (limits) on participating country's emissions are established. To meet these limits countries, in turn, set 'caps' (allowances or credits: 1 convertible and transferable credit = 1 metric tonne of CO2-e emissions) for operators. Operators that meet the agreed 'caps' can then sell unused credits to operators who exceed 'caps'. Operators can then choose the most cost-effective way of reducing emissions. Individual carbon credits would operate in a similar way cf. carbon offset.

  • climate change – a change in weather over time and/or region; usually relating to changes in temperature, wind patterns and rainfall; although may be natural or anthropogenic, common discourse carries the assumption that climate change is anthropogenic.
  • climate – the general variations of weather in a region over long periods of time; the "average weather" cf. weather.

  • coercion - process of making participants engage with a process by force rather than by convincing argument and education.

  • desertW – an area that receives an average annual precipitation of less than 250mm rain per year or an area in which more water is lost than falls as precipitation.
  • desertification - the degradation of land in arid, semi arid and dry sub-humid areas resulting from various climatic variations, but primarily from human activities.
  • detritivoreW (detritus feeder) - animals and plants that consume detritus (decomposing organic material), and in doing so contribute to decomposition and the recycling of nutrients.
  • detritusW - non-living particulate organic material (as opposed to dissolved organic material).
  • developing countries – development of a country is measured using a mix of economic factors (income per capita, GDP, degree of modern infrastructure (both physical and institutional), degree of industrialisation, proportion of economy devoted to agriculture and natural resource extraction) and social factors (life expectancy, the rate of literacy, poverty). The UN-produced Human Development Index (HDI) is a compound indicator of the above statistics. There is a strong correlation between low income and high population growth, both within and between countries. In developing countries, there is low per capita income, widespread poverty, and low capital formation. In developed countries there is continuous economic growth and a relatively high standard of living. The term is value-laden and prescriptive, as it implies a natural transition from "undeveloped" to "developed" when such transitions can instead be imposed. Although poverty and physical deprivation are clearly undesirable, it does not follow that it is therefore desirable for "undeveloped" economies to move towards affluent Western-style "developed" free market economies. The terms "industrialised" and "non-industrialised" are no different in this assumption.
