Q

is our traditional conservation approach working?

A

Biodiversity loss and ecosystem damage is occurring at an unprecedented rate and is having a negative impact on human livelihoods. Information on ecosystem services can help to communicate the value of nature to decision-makers in the hope of reversing this trend.

29
Q

what is the ecosystem services and biodiversity argument?

A

The argument (generally supported by the scientific research) is that greater biodiversity results in more resilient, reliable and healthier ecosystems able to better deliver important services to people. So improving biodiversity will in many cases improve the benefits that we receive from nature.

30
Q

what is the SPR model?

A

State, Benefits, Responses and Pressures

31
Q

what is the SPR model used for?

A

This benefit fits into the classic S-P-R model - If we can reduce pressures on biodiversity we can improve the state of biodiversity which enhances the benefits delivered to people from ‘ecosystem services’. The generation of benefits supports more effective responses which then feeds back positively by further reduces pressures.

32
Q

what does IPBES stand for?

A

Intergovernmental Platform on Biodiversity and Ecosystem Services

33
Q

what does the IPBES do?

A

Intergovernmental Platform on Biodiversity and Ecosystem Services

34
Q

what are the aspirations of the IPBES

A

The aspiration is to: (1) provide guidance on production and integration of assessments from across all scales; (2) aid regional and sub-regional assessments in biodiversity and ecosystem services; (3) fast track assessment in pollination and food production; and (4) fast track methodological assessment on value, valuation, and accounting

35
Q

what can valuing ecosystem services achieve?

A

(1) Raise awareness and build public and government support for better decisions; (2) Demonstrate additional benefits from conservation of species/sites/habitats; (3) Identify the costs and benefits of conservation and spread them more fairly among stakeholders; and (4) Enhance economic sustainability and human well-being.

36
Q

why is economics at the core of conservation?

A

Because ecosystem services are often excluded from decisions because they don’t enter the market (i.e. benefits are provided for free). Name some examples of these benefits.

37
Q

what is economics?

A

Economics is not about finance (the study and management of money), commence (the buying and selling of goods) or business (the actions involved in making profits). Economics is much broader than any of these. Economics is the study of how people make choices under conditions under conditions of scarcity, and of the results of these choices for society (Frank and Bernanke 2003). Therefore, it’s about people and their choices and how they respond to incentives.

38
Q

what are the fundamentals of economics?

A
  • Social cost = Private cost + External cost
  • Social benefit = Private benefit + External benefit
  • Net social benefit = Positive difference between social benefit and social cost
39
Q

what is GDP

A

Gross Domestic Product

40
Q

what is natural capital?

A

Natural capital is a stock, from which people derive benefits. Natural capital is the basis not only of production but of life itself

41
Q

what does natural capital include?

A
  • Resources - renewable and non-renewable materials
  • Sinks - that absorb, neutralise or recycle wastes
  • Processes - such as climate regulation
42
Q

what is NDP

A

net domestic product

43
Q

what is social capital

A

concerns the institutions that help us maintain and develop human capital in partnership with others; e.g. families, communities, businesses, trade unions, schools, and voluntary organisations.

44
Q

what is manufactured/produced capital?

A

comprises material goods or fixed assets which contribute to the production process rather than being the output itself – e.g. infrastructures and buildings.

45
Q

what is financial capital?

A

plays an important role in our economy, enabling the other types of capital to be owned and traded. But unlike the other types, it has no real value itself but is representative of natural, human, social or manufactured capital; e.g. shares, bonds or banknotes

46
Q

what is inclusive wealth?

A

The social value (not dollar price) of a country’s capital assets, including natural capital, human capital and produced capital

47
Q

what is the inclusive weath index?

A

. The Inclusive Wealth Index was launched by the UN in 2012 in an effort to overcome the environmental shortfalls of other indicators such as GDP and the Human Development Index. By assessing changes over time in natural capital (e.g. forests, watersheds, fossil fuels, fisheries), in addition to produced (manufactured) and human capital, Inclusive Wealth emphasises the changing state of a country’s natural resource base, and its fundamental impact on economic and social sustainability.

48
Q

what are indicators for the state of biodiversity?

A
  1. species’ population trends
  2. extinction risk,
  3. habitat extent and condition
  4. community composition
49
Q

what are the indicators for pressures?

A
  1. resource consumption
  2. invasive alien species
  3. nitrogen pollution
  4. Overexploitation
  5. climate change impacts
50
Q

what are the indicators for responses in terms fo valuing nature?

A
  1. extent and biodiversity coverage of protected areas
  2. sustainable forest management
  3. policy responses to invasive alien species
  4. biodiversity-related aid
51
Q

what can valuing ecosystem services do?

A 
1. Raise awareness and build public and
government support for better decisions
2. Demonstrate additional benefits from
conservation of species/sites/habitats
3. Identify the costs and benefits of conservation
and spread them more fairly among
stakeholders
4. Enhance economic sustainability and human
well-being
52
Q

what 3 things should we measure when valuing nature?

A

core processes
beneficial processes
benefits

53
Q

what areas of core processes should be measured for valuing nature?

A

photosyntehsis
water cycling
ecological interactions

54
Q

what areas of beneficial processes should be measured for valuing nature?

A

primary production
water purification
pollination

55
Q

what areas of benefits should be measured for valuing nature?

A

timber
drinking water
food

56
Q

which environmental problems are hinged on economics?

A

Ecosystem service benefits represent positive
externalities
• Ecosystem services as well as mineral deposits,
soil nutrients, fossil fuels are all capital assets
• Loss of wealth due to ecosystem degradation is
not reflected in current economic accounts
• So conversion occurs because private benefits
often greater than private costs, and externalities
are not accounted for

57
