- Conservation vs. development.
- Land abandonmentecosystem recovery or degradation?
- Forest transitionsto be or not to be enhanced?
- Suburbanizationspontaneous process or political choice?
5. Introduction This thesis is aimed at
- Helping to overcome binary distinctions to better understand
the coupled SES and its change over time in a holistic way.
- Showing that some rural activities are indispensable for the
conservation of cultural landscapes.
- Shedding light on the effects of forest recoveries on water
discharge and biodiversity at a local scale.
- Supporting the notion of historical interrelatedness and
hybridity between the rural and the urban domains.
- Showing how suburbanization is the outcome of political
struggles between different social groups with unequal distribution
of the costs and benefits of socioecological change.

Introduction Global change in the Mediterranean 9. Research
questions
- Land-use changes, climate changes, and hydrological
changes:
-
- Is the increase in forest cover after land abandonment
experienced by MMA leading to reduced water yields from the
catchments?
-
- What is the role of changing climate and how does it interact
with land-use changes in the hydrological balance of the
catchments?
-
- May changes in the biodiversity of small streams be expected
due to global change induced hydrological changes?
10. Research questions
- Mountain areas and urban centers:
-
- What was the role of MMA in the vicinity of growing urban
centers during the industrialization process and how did it change
over time?
-
- How did the their SES adapt to the growing demand of materials
and energy?
-
- How were the local management practices related to their
particular cultural context, and how did they contribute to the
maintenance of a diverse SES?
-
- Is the debate about the conservation of biocultural diversity
useful in industrialized countries?
11.
- Suburbanization and socioecological projects:
-
- How different visions of the future by different social groups
collided in the process of suburbanization of the countryside?
-
- Whose socioecological projects prevailed and why?
-
- How have landless peasants been affected by the processes of
suburbanization? What should be learnt from their memories?
-
- Why some areas of the countryside specialize in elite
suburbanization while others follow the path of land
abandonment?

- In mountain areas historically devoted to forestry, the
afforestation experienced in the last decades is too small to have
a significant influence on runoff.
- Decreases in RR ratio may be related to drier periods, longer
droughts and increased potential evapotranspiration rates.
- Specific measures such as enhancing the pools that keep water
throughout the year are needed to maintain aquatic fauna
species.
- The hydrological effects of increased canopy covers should be
considered in further studies (Llorens & Domingo, 2007; Muzylo
et al., 2009).

IUCN Species Area 51. Case study 2 Conclusions
- The abandonment of a set of agrosilvopastoral practices of
adaptive management is related to a decline of several species from
different taxonomic groups.
- Biocultural degradation rather than Ecosystem recovery (Aide
& Grau, 2004) in Mediterranean mountain areas experiencing land
abandonment processes.
- Socioecological heritageas a distinctive set of socioecological
interactions and practices which yield a particular configuration
in both cultural and biological diversities.
- Alternative resource management practices may be devised upon
such heritage.

it was not at all nostalgic, it was rather the other way around. It
was more like a revolutionary vision, as far as you could realize
that there was another possibility in the world: a parallel world

study 3 Introduction: urbanization and water
- City and nature are not antithetical entities; cities
metabolize nature, producing new, urbanized socionatures.
- Produced socionatures may be seen as better or worse depending
on different valuation criteria.
- Uneven power relationships produce uneven control of resources,
and socially uneven (urban) landscapes with unequal distribution of
the costs and benefits of socioecological change among social
groups .
- How, by whom and for what purpose water is mobilized in the
process of urbanization?

- Exhaustive review of the City Archives of Matadepera.
- Collection of formal communications between Matadepera's
municipal authorities and external individuals or agencies
(1919-1979).
- Key documents about water, land and political conflicts were
identified, photocopied and text coded.
- Semi-structured interviews to 17 locals born between 1913 and
1958. Recording, transcription and content analysis.
58. Case study 3 Results:an uneven society to begin with
(1886)
- 9 families own 90%of land; 60 families the remaining 10% (574
residents).
- Forestry, vines, lime: dont need much water.
- But at turn of century urban elites increasingly attracted by
the clean air of the mountains.
- No surface water, capital needed to access groundwater.

67. Case study 3 Conclusions
- Matadepera became a rich suburb through fights for land and
water, not through a spontaneous and inevitable process.
- Water was not scarce per se, but for gentrified
suburbanization.
- Scarcity and progress were discursively mobilized to justify
the chosen path of development.
- Progress can mean different things to different people.
- The question is whose vision of the future came to be realized
and whose vision (and livelihood) to be erased.
68. General conclusions Rural-urban socioecological
transformation (I)
- Agrosilvopastoral management, embedded in particular
institutional settings and worldviews, provided resilience to the
SES while keeping it highly productive for the urban centers.
- Land abandonment leads to a biocultural degradation in
MMA.
- Forest recoveries in MMA are not necessarily good per se at
local scales.
- The recovery of former agrarian cover in order to compensate
the effects of climate decreasing the runoff would not have a
significant effect unless large forested areas were converted into
fields or pastures.
69. General conclusions Rural-urban socioecological
transformation (II)
- The inherited impacts of the elite suburbanization path
question the characterization of the transformations experienced in
MMA as progress.
- Denying the spontaneous nature of suburbanization strengthens
the argument of citizen groups that are fighting to reverse the
legacy of such an urban model.
- Small and landless peasants have particularly suffered the
socioecological transformations, for being farmers in an urbanizing
metropolis and for being (sons of) the losers of the Civil
War.
- Avoid to offer a romantic view of the rural past since large
inequalities dominated the SES.
70. Conclusions Interdisciplinarity, languages, and the
otherness
- Predisposition to understand other paradigms, languages and
methods, and ability to integrate them in an emerging
language.
- Experience of the eldest not only enriched the understanding of
the SES, but some of their claims were incorporated into our
account to refute progressive narratives.
- Considering the management practices of our ancestors as a
legacy is a way to recognize the forgotten rural origin of our
current culture.
- Seizing invisible realities through their traces and imagining
radically new ones.
71. Conclusions Hybridity and neutrality
- From dualistic balance to the fusion of society and nature
through metabolic production.
- As hybridity increases, ethical neutrality decreases with
positioned research.
- A suitable combination of different degrees of socioecological
hybridity may be suitable to understand the complex dynamics of
global (land) change and biodiversity conservation
- and useful to overcome binary distinctions:
- conservation vs. development
- protected vs. non-protected areas
