Taking into account
Coproduction processes
➤ Articulates Ecosystem services (ES) and Ecosystem structures & functions

➤ Articulates ES and benefits (Fisher et al. 2009:646)

➤ Distinguishes intermediate and final ES (Boyd & Banzhaf 2007)

➤ Acknowledges coproduction processes (Palomo et al. 2016)

But cascade models **do not explicitly take into account ecosystem-based nuisances**
"Ecosystem disservices are the ecosystem generated functions, processes and attributes that result in **perceived or actual** negative impacts on human wellbeing" (Shackleton et al. 2016:590)

(Shackleton et al. 2016)

<figure><img src="image_9.png" /><figcaption>Figure 1. Ecosystem disservices within the continuum from natural to social hazards. The social-ecological system boundary is not solid to reflect that the boundaries between ecosystem disservices and other harmful phenomena (termed hazards) are usually fuzzy</figcaption></figure>

EDS are not

➤ Reduced or constrained supply of an ES

➤ Events or phenomena that have no ecosystem origin

➤ Social responses

➤ Land management actions that impact biodiversity

Defining and articulating ES and EDS

Delineating E(D)S from benefits and detriments

Integrating coproduction processes

Conceptualizing the ES/EDS cascade model

Application in a case study in Brazil
A constructivist definition of ES and EDS

ES and EDS as
social constructs

They are subjective interpretations, socially situated
and constructed, of ecological phenomena

Intermediate vs.
final

They influence human well-being
either directly or indirectly

<figure><img src="image_11.png" /></figure>

Intermediate

Final

➤ **Ecosystem services:** the ecological structures, functions and processes that **people recognize as supporting**, directly or indirectly, their wellbeing

➤ **Ecosystem disservices:** the ecological structures, functions and processes that **people recognize as detrimental**, directly or indirectly, to their well-being
ES and EDS must be
ecosystem-based

<figure><img src="image_12.png" /></figure>

Ecosystem structures and functions

Intermediate and final
services and disservices

Benefits & detriments
People are affected
by ES and EDS

<figure><img src="image_13.png" /></figure>

People react

People's mental models (representations, knowledge, motivation)

People's well-being (material and non-material)

Through management and coping practices

Through value attribution processes

Through institutional arrangements
The ES/EDS cascade model

* ES and EDS are produced at different organizational levels

* ES and EDS can be intermediate or final

* Benefits and detriments are either material or non-material

* ES and EDS induce a response from the society at different levels

An application example in Brazil

<figure><img src="image_15.png" /></figure>

Semi-structured interviews in 46 farms (~120 000 ha)

➤ Farming systems and strategies

➤ Perceived advantages & drawbacks associated with trees and forests

<figure><img src="image_16.png" /></figure>
An application example in Brazil

<figure><img src="image_17.png" /></figure>

30 ES (15 final + 15 intermediate) and 18 EDS (6 final + 12 intermediate)

... which allowed us to
identify how farmers cope
with ecosystem disservices

<figure><img src="image_22.png" /></figure>
➤ Capturing the **complex trade-offs** associated with any conservation decision

➤ Understanding who benefit and who suffer from a decision, and tackling **social conflicts** and **justice and equity issues**

➤ Balanced systemic approach of the complexity of human-nature relationships

➤ Towards innovative pathways to **cope with disservices without harming ecosystems**

<figure><img src="image_23.png" /></figure>

➤ Anthropocentric and utilitarian framework

➤ The **ES / EDS dichotomy** might not always be easy to sustain as the frontier between the two could be porous

➤ What added value compared to an **environmental values framework**?
