A man made world. The influence of man on earth: “People and societies are the biggest drivers of global change“.

The world we live in

The net gains in human well-being and economic development occurred at the cost of degradation of ecosystems.

Is it sustainable?

Ecosystem services rely on biodiversity

Maintaining biodiversity is essential to the supply of

ecosystem services, as well as their health and resilience

Linking biodiversity to ecosystem functioning

Cardinale et al. 2012

Biodiversity underpins all ecosystem services

Biodiversity plays a wide range of functional roles in ecosystems (well established).

+ Ecosystem functions are more stable through time in experimental ecosystems with relatively high levels of biodiversity (established but incomplete evidence); and there are comparable effects in natural ecosystems (likely).

the level and stability of ecosystem services tend to improve with increasing biodiversity.

Biodiversity is at the basis

Transitions between states occur in many ecological systems – states differ in their capacity to provide ecosystem services

• Nonlinear critical transitions are forecast to increase

Scheffer et al. (2009) Nature; Bestelmeyer et al. (2011) Ecosphere

Mechanisms of transitions (following the authors terminology)

• Need for early-warning signs, not only looking to drivers, but to measure effects on ecosystems

Mechanisms of transitions between ecosystems states and tipping points

An ecosystem can experience a shift to a new state, with significant changes to biodiversity and the services they provide.

Tipping points also have at least 1 of the following characteristics: ✤ The change becomes self perpetuating (deforestation reduces regional rainfall, which increases fire-risk, which causes forest dieback and further drying). ✤ There is a threshold beyond which an abrupt shift of ecological states occurs. ✤ The changes are long-lasting and hard to reverse. ✤ There is a significant time lag between the pressures and the appearance of impacts.

Ecosystem functioning is extremely complex and thus monitoring the effects of environmental change factors in ecosystems in an integrative perspective can make use of ecological indicators. Common ecological Indicators are based on biodiversity measures since they integrate the ecosystem functioning.

Functional Diversity – Potentially Universal

Díaz, S. & Cabido, M. (2001) Trends in Ecology & Evolution 16, 646-655.

Functional diversity groups: groups of species respond similarly to an environmental factor or that have similar functions in ecosystems; Functional diversity is associated with the functioning of the ecosystem it is right also associated with the service rendered by this.

• Stakeholders can easily identify benefits given by the montado altough they cannot recognize them as Ecosystem Services

• Strenghts, weaknesses, challenges and drivers of change identified by the stakeholders:

Strenghts

•Multifunctionality

•Resistence of the system

•Adaptability of trees

Weaknesses

•Quality of management

•Policies of support and territorial planning

•Susceptibilities of the system

•Knowledge and formation

•Economic valuation of provisioning services

Challenges

•Enhance economic sustainability and ecological continuity

•Adaptation and mitigation to climate change

•Quantify and valuate ES

Drivers of change

•Diversification of products (cork products, gourmet, aromatics, etc)

•Tourism opportinnities

•Greening and forest certification

•Mortality of trees

•Increasing overgrazing

• 2 workshops done with NGOs, researchers, companies, government agencies

Goal 1 - Evaluate stakeholders perceptions of ES delivered by the montado

First Results

• Workshops at the farmstead level with the stakeholders of each LTER montado area • Face-to-face surveys at the farm scale to identify preferences of montado natural values by visitors and other users and to evaluate economically this system • On-line surveys to evaluate public perception of Cultural ES of the montado with economic valuation

Future research

• The Forest Scenario was the most valuable;

• This high value is mainly due to cork;

• The Urbanization Scenario was the worst;

• Results are quite similar between methods.

Goal 2 - Evaluate system responses to changes trough the development of scenarios Goal 3 – Test instruments and tools

First Results

We assessed and mapped 3 ES (cork, carbon stock and sequestration) using InVEST and TESSA in Ca. das Lezírias in 4 scenarios

• Both tools were usefull to estimate and map ES under diferente scenarios;

• Both methods are largely dependente on the quality of primary data making them uncertain and user dependent;

• The specificity of some data input is also demanding for non-specialists;

• The complexity of the montado system increases the complexity of estimates

Values and perceptions Social functioning?

• Face-to-face questionnaires with open questions addressing:

- motivation for visit and use of the parks

- place attachment and perceived benefits

- perception and valuation of biodiversity and ecosystem

services provided

- health and well-being

Ecosystem services assessment

• In your opinion which of these green areas contribute most for:

Food production, air purification, temperature regulation, carbon sequestration, flood regulation, pollination, habitat for species, social interaction, inspiration, spiritual experience, recreation

Page 40: Biodiversity: back to basics of ecosystem services · Biodiversity: back to basics of ecosystem services Biodiversidade: voltar à origem dos serviços de ecossistema Cristina Branquinho,

Final Remarks • Biodiversity is the basis of Ecosystem Services;

• Functional diversity is a good measure of Ecosystem Services;

• We must develop better the trade-offs methodology;

• We need to test this under different case studies
