The <strong>TEEB</strong> <strong>Manual</strong> <strong>for</strong> <strong>Cities</strong>: Ecosystem Services in Urban Management3.4 Concluding remarksEcosystem services are essentialto cities. It has been shown throughresearch and through the practicalexamples provided in this manual,that incorporating ecosystem servicesinto city management is possible andextremely beneficial. Such a focus willreduce ef<strong>for</strong>ts and costs over the longterm,boost the local economy, andimprove the quality of life <strong>for</strong> all citizens.It is easy to begin the process of valuingecosystem services, <strong>for</strong> example, byidentifying an ecosystem service that hasnot previously been recognised, or bydrawing on studies from similar contexts.It is, however, important to considerthe larger context and the full range ofecosystem services across a spatial/geographic area, and not just examinean ecosystem service in isolation. Inmany cases, once a shift has been madein the way cities think about the localenvironment, the move to incorporatingthe ecosystem services concept willfollow easily.As mentioned throughout this manual,involving stakeholders (including thefinance and economic developmentdepartments) as key role players, at everystep of the process, is essential to build asense of awareness, understanding andownership.It is hoped that, above all, this manualwill inspire cities to start thinking abouthow a focus on ecosystem servicesand their valuation can be useful inthe local situation. This approachhas been demonstrated to be effectiveand valuable, and it can be easilyper<strong>for</strong>med even with limited resources –the fact of the matter is it is a long-terminvestment that will save resources intothe future.Incorporating ecosystem services into city management is possible and extremely beneficial.Stephen Granger37
The <strong>TEEB</strong> <strong>Manual</strong> <strong>for</strong> <strong>Cities</strong>: Ecosystem Services in Urban ManagementGlossaryBiodiversity: the variability among living organisms, includingterrestrial, marine and other aquatic ecosystems.Biodiversity includes diversity within species, betweenspecies, and between ecosystems.Biological diversity: see biodiversity.Biofuel: A fuel derived from biomass like plant matter instead offossil fuel resources such as mineral oil.Biological control: The use of natural enemies (diseases,parasites, predators) to regulate populations of pest species.Biome: A large geographic region, characterized by life <strong>for</strong>msthat develop in response to relatively uni<strong>for</strong>m climaticconditions. Examples are tropical rain <strong>for</strong>est, savanna,desert and tundra.Carbon sequestration: The process by which plants take incarbon dioxide gas and convert it into solid carbon as partof their structural components, as they grow.Climate change: In the modern day context this usuallyrefers to human-induced change in the earth’s climate,caused mostly by the production of greenhouse gasessuch as carbon dioxide from engines (factories, cars, etc.).This change is happening at a rapid rate and poses a threatto both humankind and biodiversity.Conservation (also: biodiversity conservation):The preservation of biological units such as genes, species,populations and ecosystems to prevent their extinction.Degradation, Environmental: The process of loss of qualityof the environment, leading to a reduction in ecosystemfunction and loss of ecosystem services.Desertification: A <strong>for</strong>m of environmental degradation that ischaracterised by a change in the natural landscape andenvironment to look more like a desert, with drier, dustierconditions. It can be caused by overgrazing, removal ofnatural vegetation, bad agricultural practices and drought.Diversity: The sum total of variety of biological units at variousscales, be it genes, species, populations, or ecosystems.Ecosystem health or Ecological stability: A description ofthe dynamic properties of an ecosystem. An ecosystemis considered stable or healthy if it returns to its originalstate after a disturbance, exhibits low temporal variabilitywith time, or does not change dramatically in the face ofdisturbance.Ecosystem: a dynamic complex of plant, animal andmicroorganism communities and their environmentinteracting as a functional unit.Ecosystem services: The direct and indirect contributions ofecosystems to human well-being. The concept ‘ecosystemgoods and services’ is synonymous with ecosystemservices.Ecotourism: Travel undertaken to visit natural sites or regionswithout harming them.Endemic / endemism: A species, or taxonomic group, that isrestricted to a particular geographic region.Extinct: A species no longer represented by living individuals.Microorganisms: Organisms which are so small that theyrequire a microscope to be seen.Organisms: Any individual life <strong>for</strong>m that can react to stimuli,reproduce, grow, and maintain itself - plants, animals, fungi,viruses, bacteria and other <strong>for</strong>ms of life.Parasite: The organism that benefits in an interspecificinteraction in which individuals of two species livesymbiotically with one organism benefitting and the otherbeing harmed. A parasite lives in intimate association withits host.Payment <strong>for</strong> Ecosystem Services: A mechanism wherebyfinancial, or other, compensation is used to promote theconservation of an ecosystem, or encourage restorationand rehabilitation of the ecosystem.Predator: An organism that benefits in an interspecificinteraction in which it kills and feeds on prey. A predatorlives in loose association with its prey.Resilience, ecosystem: The capacity of an ecosystem totolerate disturbance without collapsing.Restoration: In the biodiversity context, this refers to turningan area back to its natural state by, <strong>for</strong> example, re-plantingnative vegetation. It is also relevant when it refers to therepairing of buildings, as this can be done in such a way tobenefit biodiversity.Species: One of the basic units of biological classification, aspecies is often defined as a group of living things that arecapable of interbreeding and producing fertile offspring.Sustainability: Development and maintenance based on the useof resources that can be replaced or renewed and there<strong>for</strong>enot depleted. Economic development is sustainable only ifit takes into account the limited resources of the biosphere.Vector: The means by which a pathogen, parasite or invasivealien species travels from one geographic area, or host, toanother. For example, the vector of the malaria parasite isthe Anopheles mosquito.38
