Carbon sequestration in community forests: trade-offs, multiple outcomes and institutional diversity in the Bolivian Amazon

Carbon sequestration in community forests presents a major challenge for the Reducing Emissions from Deforestation and Forest Degradation (REDD+) programme. This article uses a comparative analysis of the agricultural and forestry practices of indigenous peoples and settlers in the Bolivian Amazon to show how community-level institutions regulate the trade-offs between community livelihoods, forest species diversity, and carbon sequestration. The authors argue that REDD+ implementation in such areas runs the risk of: 1) reinforcing economic inequalities based on previous and potential land use impacts on ecosystems (baseline), depending on the socio-cultural groups targeted; 2) increasing pressure on land used for food production, possibly reducing food security and redirecting labour towards scarce off-farm income opportunities; 3) increasing dependence on external funding and carbon market fluctuations instead of local production strategies; and 4) further incentivising the privatization and commodification of land to avoid transaction costs associated with collective property rights. The article also advises against taking a strictly economic, market-based approach to carbon sequestration, arguing that such an approach could endanger fragile socio-ecological systems. REDD+ schemes should directly support existing efforts towards forest sustainability rather than simply compensating local land users for avoiding deforestation and forest degradation

Can the green economy enhance sustainable mountain development? The potential role of awareness building

Mountain socio-ecological systems produce valuable but complex ecosystem services resulting from biomes stratified by altitude and gravity. These systems are often managed and shaped by smallholders whose marginalization is exacerbated by uncertainties and a lack of policy attention. Human–environment interfaces in mountains hence require holistic policies. We analyse the potential of the Global Mountain Green Economy Agenda (GMGEA) in building awareness and thus prompting cross-sectoral policy strategies for sustainable mountain development. Considering the critique of the green economy presented at the Rio + 20 conference, we argue that the GMGEA can nevertheless structure knowledge and inform regional institutions about the complexity of mountain socio-ecological systems, a necessary pre-condition to prompt inter-agency collaboration and cross-sectoral policy formulation. After reviewing the content of the GMGEA, we draw on two empirical cases in the Pakistani and Nepali Himalayas. First, we show that lack of awareness has led to a sequence of fragmented interventions with unanticipated, and unwanted, consequences for communities. Second, using a green economy lens, we show how fragmentation could have been avoided and cross-sectoral policies yielded more beneficial results. Project fragmentation reflects disconnected or layered policies by government agencies, which inherently keep specialized agendas and have no incentive to collaborate. Awareness makes agencies more likely to collaborate and adopt cross-sectoral approaches, allowing them to target more beneficiaries, be more visible, and raise more funds. Nevertheless, we also identify four factors that may currently still limit the effect of the GMGEA: high costs of inter-agency collaboration, lack of legitimacy of the green economy, insufficiently-secured smallholder participation, and limited understanding of the mechanisms through which global agendas influence local policy.

Land system science and sustainable development of the earth system: A global land project perspective

Land systems are the result of human interactions with the natural environment. Understanding the drivers, state, trends and impacts of different land systems on social and natural processes helps to reveal how changes in the land system affect the functioning of the socio-ecological system as a whole and the tradeoff these changes may represent. The Global Land Project has led advances by synthesizing land systems research across different scales and providing concepts to further understand the feedbacks between social-and environmental systems, between urban and rural environments and between distant world regions. Land system science has moved from a focus on observation of change and understanding the drivers of these changes to a focus on using this understanding to design sustainable transformations through stakeholder engagement and through the concept of land governance. As land use can be seen as the largest geo-engineering project in which mankind has engaged, land system science can act as a platform for integration of insights from different disciplines and for translation of knowledge into action.

Marginal lands or marginal people? Analysing key processes determining the outcomes of large-scale land acquisitions in Lao PDR and Cambodia

This chapter aims to overcome the gap existing between case study research, which typically provides qualitative and process-based insights, and national or global inventories that typically offer spatially explicit and quantitative analysis of broader patterns, and thus to present adequate evidence for policymaking regarding large-scale land acquisitions. Therefore, the chapter links spatial patterns of land acquisitions to underlying implementation processes of land allocation. Methodologically linking the described patterns and processes proved difficult, but we have identified indicators that could be added to inventories and monitoring systems to make linkage possible. Combining complementary approaches in this way may help to determine where policy space exists for more sustainable governance of land acquisitions, both geographically and with regard to processes of agrarian transitions. Our spatial analysis revealed two general patterns: (i) relatively large forestry-related acquisitions that target forested landscapes and often interfere with semi-subsistence farming systems; and (ii) smaller agriculture-related acquisitions that often target existing cropland and also interfere with semi-subsistence systems. Furthermore, our meta-analysis of land acquisition implementation processes shows that authoritarian, top-down processes dominate. Initially, the demands of powerful regional and domestic investors tend to override socio-ecological variables, local actors’ interests, and land governance mechanisms. As available land grows scarce, however, and local actors gain experience dealing with land acquisitions, it appears that land investments begin to fail or give way to more inclusive, bottom-up investment models.

Linking livelihood strategies with a regional level landscape mosaic to explore trade-offs between forest conservation and human wellbeing in a Madagascar biodiversity hotspot

The north-eastern escarpment of Madagascar contains the island’s last remaining large-scale humid forest massifs surrounded by diverse small-scale agricultural mosaics. There is high deforestation mainly caused by shifting cultivation practiced by local land users to produce upland rice for subsistence. Today, large protected areas restrict land users’ access to forests to collect wood and other forest products. Moreover, they are no more able to expand their cultivated land, which leads to shorter shifting cultivation cycles and decreasing plot sizes for irrigated rice and cash crop cultivation. Cash crop production of clove and vanilla is exposed to risks such as extreme inter-annual price fluctuations, pests and cyclones. In the absence of work opportunities, agricultural extension services and micro-finance schemes people are stuck in a poverty trap. New development strategies are needed to mitigate the trade-offs between forest conservation and human well-being. As landscape composition and livelihood strategies vary across the region, these strategies need to be spatially differentiated to avoid implementing generic solutions, which do not fit the local context. However, up to date, little is known about the spatial patterns of shifting cultivation and other land use systems at the regional level. This is mainly due to the high spatial and temporal dynamics inherent to shifting cultivation, which makes it difficult to monitor the dynamics of this land use system with remote sensing methods. Furthermore, knowledge about land users’ livelihood strategies and the risks and opportunities they face stems from very few local case studies. To overcome this challenge, firstly, we used remote sensing data and a landscape mosaic approach to delineate the main landscape types at the regional level. Secondly, we developed a land user typology based on socio-ecological data from household surveys in 45 villages spread throughout the region. Combining the land user typology with the landscape mosaic map allowed us to reveal spatial patterns of the interaction between landscapes and people and to better understand the trade-offs between forest conservation and local wellbeing. While shifting cultivation systems are being transformed into more intensive permanent agricultural systems in many countries around the globe, Madagascar seems to be an exception to this trend. Linking land cover information to human-environmental interactions over large areas is crucial to designing policies and to inform decision making for a more sustainable development of this resource-rich but poverty-prone context.

Challenges in the participatory assessment of sustainable management practices in dryland ecosystems under regime shifts

Regime shifts, defined as a radical and persistent reconfiguration of an ecosystem following a disturbance, have been acknowledged by scientists as a very important aspect of the dynamic of ecosystems. However, their consideration in land management planning remains marginal and limited to specific processes and systems. Current research focuses on mathematical modeling and statistical analysis of spatio-temporal data for specific environmental variables. These methods do not fulfill the needs of land managers, who are confronted with a multitude of processes and pressure types and require clear and simple strategies to prevent regime shift or to increase the resilience of their environment. The EU-FP7 CASCADE project is looking at regime shifts of dryland ecosystems in southern Europe and specifically focuses on rangeland and forest systems which are prone to various land degradation threats. One of the aims of the project is to evaluate the impact of different management practices on the dynamic of the environment in a participatory manner, including a multi-stakeholder evaluation of the state of the environment and of the management potential. To achieve this objective we have organized several stakeholder meetings and we have compiled a review of management practices using the WOCAT methodology, which enables merging scientific and land users knowledge. We highlight here the main challenges we have encountered in applying the notion of regime shift to real world socio-ecological systems and in translating related concepts such as tipping points, stable states, hysteresis and resilience to land managers, using concrete examples from CASCADE study sites. Secondly, we explore the advantages of including land users’ knowledge in the scientific understanding of regime shifts. Moreover, we discuss useful alternative concepts and lessons learnt that will allow us to build a participatory method for the assessment of resilient management practices in specific socio-ecological systems and to foster adaptive dryland management.

Contextualizing local-scale point sample data using global-scale spatial datasets: Lessons learnt from the analysis of large-scale land acquisitions

This paper examines how the geospatial accuracy of samples and sample size influence conclusions from geospatial analyses. It does so using the example of a study investigating the global phenomenon of large-scale land acquisitions and the socio-ecological characteristics of the areas they target. First, we analysed land deal datasets of varying geospatial accuracy and varying sizes and compared the results in terms of land cover, population density, and two indicators for agricultural potential: yield gap and availability of uncultivated land that is suitable for rainfed agriculture. We found that an increase in geospatial accuracy led to a substantial and greater change in conclusions about the land cover types targeted than an increase in sample size, suggesting that using a sample of higher geospatial accuracy does more to improve results than using a larger sample. The same finding emerged for population density, yield gap, and the availability of uncultivated land suitable for rainfed agriculture. Furthermore, the statistical median proved to be more consistent than the mean when comparing the descriptive statistics for datasets of different geospatial accuracy. Second, we analysed effects of geospatial accuracy on estimations regarding the potential for advancing agricultural development in target contexts. Our results show that the target contexts of the majority of land deals in our sample whose geolocation is known with a high level of accuracy contain smaller amounts of suitable, but uncultivated land than regional- and national-scale averages suggest. Consequently, the more target contexts vary within a country, the more detailed the spatial scale of analysis has to be in order to draw meaningful conclusions about the phenomena under investigation. We therefore advise against using national-scale statistics to approximate or characterize phenomena that have a local-scale impact, particularly if key indicators vary widely within a country.

Systemic evaluation - a contribution to Swiss development research

Systemic thinking may be traced hack to several roots. Some of them can he found in Taoism, the basic concepts of which are the achievement of cosmic harmony and a well-balanced social order. Others can be found in Greek philosophy. Similarly, modern physics in its most advanced branches is now recognizing basic aspects of these same roots in a scientific guise. The more the process of research and theory building advances, the more phenomena are recognized as complex and interdependent with other phenomena. Interdisciplinary research and the constitution of new disciplines are contributing to a scientific approximation of integral reality, which is becoming more and more like the one everyone knows as prescientific. The transcendence of the narrow boundaries of positivist sciences seems to be becoming a necessity for scientific evolution. The ecological crisis of the twentieth century may itself lead to increased systemic thinking, and it is in full awareness of the fact that there are no simple solutions that the systemic evaluator tries to cope with the problems of the dynamics of social and political interventions in the Third World as a means of development co-operation..

Sociedad y política en argentina (1955-1976) : La 'nueva izquierda' entre la protesta social y la política revolucionaria

El presente proyecto de investigación analiza la relación entre sociedad y política en la Argentina entre 1955 y 1976. Se trata de un período signado por una aguda crisis socio-política, una profunda pérdida de legitimidad de las instituciones y el Estado y en que la acelerada modernización socio-cultural posterior a 1955 se combinó rápidamente con una tendencia a la radicalización política. Uno de los primeros efectos de este proceso fue la recomposición de la izquierda. Del seno de sus partidos "tradicionales" (el Partido Comunista y Socialista) surgieron diversas formaciones de la "nueva izquierda", mientras que rupturas y transformaciones similares se verificaban en sectores nacionalistas, peronistas y cristianos. Estos nuevos actores sociales y políticos solieron orientarse hacia objetivos que proclamaron la "liberación nacional" y el "socialismo" y hacia estrategias revolucionarias. Nuestro trabajo se interesa centralmente en reconstruir los orígenes de las nuevas prácticas y organizaciones surgidas por entonces así como las formas de articulación entre demandas sociales y propuestas políticas, y entre elencos dirigentes y sectores populares. A su vez, examina una multiplicidad de "casos" que formaron parte de este social y políticamente variado campo, sin subsumirlo exclusivamente al accionar de las organizaciones armadas.

Deforesting Europe: pollen-inferred Holocene land cover change using the 'pseudobiomization' approach

Maps of continental-scale land cover are utilized by a range of diverse users but whilst a range of products exist that describe present and recent land cover in Europe, there are currently no datasets that describe past variations over long time-scales. User groups with an interest in past land cover include the climate modelling community, socio-ecological historians and earth system scientists. Europe is one of the continents with the longest histories of land conversion from forest to farmland, thus understanding land cover change in this area is globally significant. This study applies the pseudobiomization method (PBM) to 982 pollen records from across Europe, taken from the European Pollen Database (EPD) to produce a first synthesis of pan-European land cover change for the period 9000 BP to present, in contiguous 200 year time intervals. The PBM transforms pollen proportions from each site to one of eight land cover classes (LCCs) that are directly comparable to the CORINE land cover classification. The proportion of LCCs represented in each time window provides a spatially aggregated record of land cover change for temperate and northern Europe, and for a series of case study regions (western France, the western Alps, and the Czech Republic and Slovakia). At the European scale, the impact of Neolithic food producing economies appear to be detectable from 6000 BP through reduction in broad-leaf forests resulting from human land use activities such as forest clearance. Total forest cover at a pan-European scale moved outside the range of previous background variability from 4000 BP onwards. From 2200 BP land cover change intensified, and the broad pattern of land cover for preindustrial Europe was established by 1000 BP. Recognizing the timing of anthropogenic land cover change in Europe will further the understanding of land cover-climate interactions, and the origins of the modern cultural landscape.

Balancing groundwater conservation and rural livelihoods under water and climate uncertainties: An integrated hydro-economic modeling framework

In arid countries worldwide, social conflicts between irrigation-based human development and the conservation of aquatic ecosystems are widespread and attract many public debates. This research focuses on the analysis of water and agricultural policies aimed at conserving groundwater resources and maintaining rurallivelihoods in a basin in Spain's central arid region. Intensive groundwater mining for irrigation has caused overexploitation of the basin's large aquifer, the degradation of reputed wetlands and has given rise to notable social conflicts over the years. With the aim of tackling the multifaceted socio-ecological interactions of complex water systems, the methodology used in this study consists in a novel integration into a common platform of an economic optimization model and a hydrology model WEAP (Water Evaluation And Planning system). This robust tool is used to analyze the spatial and temporal effects of different water and agricultural policies under different climate scenarios. It permits the prediction of different climate and policy outcomes across farm types (water stress impacts and adaptation), at basin's level (aquifer recovery), and along the policies’ implementation horizon (short and long run). Results show that the region's current quota-based water policies may contribute to reduce water consumption in the farms but will not be able to recover the aquifer and will inflict income losses to the rural communities. This situation would worsen in case of drought. Economies of scale and technology are evidenced as larger farms with cropping diversification and those equipped with modern irrigation will better adapt to water stress conditions. However, the long-term sustainability of the aquifer and the maintenance of rurallivelihoods will be attained only if additional policy measures are put in place such as the control of illegal abstractions and the establishing of a water bank. Within the policy domain, the research contributes to the new sustainable development strategy of the EU by concluding that, in water-scarce regions, effective integration of water and agricultural policies is essential for achieving the water protection objectives of the EU policies. Therefore, the design and enforcement of well-balanced region-specific polices is a major task faced by policy makers for achieving successful water management that will ensure nature protection and human development at tolerable social costs. From a methodological perspective, this research initiative contributes to better address hydrological questions as well as economic and social issues in complex water and human systems. Its integrated vision provides a valuable illustration to inform water policy and management decisions within contexts of water-related conflicts worldwide.

Ecología política y economía de la visibilidad de los dispositivos tecnológicos de escala urbana durante el siglo XX Abriendo la caja negra

En paralelo a la superficie cotidiana de la ciudad moderna, discurre otra "ciudad invisible" o "caja negra" tecnológica, que opera, de manera silenciosa e imperceptible, al servicio de los ciudadanos. Paradójicamente, en este espacio invisible, se toman decisiones de la máxima relevancia para la ciudad: en la "caja negra", las ciudades pactan sus relaciones con la naturaleza; a través de ella, se produce la administración y distribución de los recursos que componen su metabolismo urbano. En definitiva, la "caja negra" es el conjunto de las arquitecturas donde se urbaniza la naturaleza, donde ésta pasa a ser ciudad. Y, sin embargo, ha tendido a permanecer invisible. No obstante, en el último tercio del siglo XX, se ha "abierto la caja negra" urbana y lo que era invisible ha dejado de serlo o, al menos, ha alterado su estatuto de visibilidad. El objetivo de esta tesis doctoral es evaluar las repercusiones arquitectónicas, urbanísticas y ecológicas, que conlleva este reciente fenómeno urbano que, desde hace unas décadas, está teniendo lugar en muchas de las ciudades herederas de las grandes reformas urbanas acometidas en las metrópolis europeas durante el siglo XIX, bajo el paradigma simbólico de un proyecto moderno "prometeico" y emancipador. Para abordar dicho análisis, se pondrán en relación dos parámetros urbanos elementales que han tendido a ser estudiados por separado. Por un lado, la "ecología política urbana", es decir, la red de relaciones socio-ecológicas que acontecen en la ciudad. Por otro lado, la "economía de la visibilidad", es decir, las formas de articular lo visible y lo invisible, en relación a los marcos de gobernanza. La intersección entre la "ecología política urbana" y la "economía de la visibilidad" proporciona un marco de análisis efectivo para comprender el fenómeno de la "apertura de la caja negra" y conlleva un cuestionamiento de algunas nociones dominantes en la teoría urbana y arquitectónica clásicas, como la segregación de la naturaleza, las infraestructuras y la sociedad o como las formas tradicionales de explotación ecológica del medio. Además, ofrece un criterio de análisis privilegiado para la comprensión del proceso de deslegitimación (filosófica, arquitectónica, económica, así como desde perspectivas ecológicas, sociales, de género o queer) de los modelos urbanísticos integrales modernos, herederos de los marcos antropocéntricos del siglo XIX. Por último, proporciona algunas herramientas arquitectónicas para afrontar los desafíos ecosistémicos del siglo XXI. A través del estudio de autores relevantes que han analizado esta problemática para la arquitectura, así como del estudio de casos arquitectónicos que han marcado hitos fundamentales en la consolidación urbana de los procesos asociados a la "caja negra", se concluirá que, en términos ecológicos, la ciudad moderna ha movilizado una "ecología política urbana" basada en fórmulas de sometimiento del entorno, a partir de operaciones arquitectónicas y tecnológicas invisibles. En esta tesis doctoral se estudiará la organización arquitectónica de las arquitecturas de la "caja negra" y se evaluará si el fenómeno de la "apertura de la caja negra" puede ser considerado como un síntoma de la alteración en la "ecología política urbana". 'Abriremos la caja negra" para estudiar cómo se integran en el espacio urbano los dispositivos tecnológicos de escala urbana, toda vez éstos han dejado de ser invisibles. Cómo participan, como un actor más, en la configuración de otros marcos de cohabitación, dentro de la ciudad contemporánea. ABSTRACT An 'invisible city' or technological 'black box' runs parallel to the day-to-day surface of modern cities, remaining silent, unnoticed, at the service of the citizenry. Paradoxically, this invisible space is where some of the most relevant decisions concerning the city are made: the 'black box' is where cities agree on their relationships with nature; it is used to manage and distribute the resources that form its urban metabolism. In short, the 'black box' is the collection of architectures where nature is urbanised, where it becomes a city. And in spite of all this, it has mostly remained invisible. Nevertheless, this urban 'black box' was opened during the last third of the 20th century, so what used to be invisible is invisible no more, or at least the laws governing its visibility have been altered. The purpose of this doctoral thesis is to evaluate the architectural, urban planning and ecological repercussions of this recent urban phenomenon that has been taking place for several decades in many of the cities that followed in the footsteps of the large European metropolises of the 19th century, under the symbolic paradigm of a modern 'prometheic' and emancipating project. This analysis shall be done by juxtaposing two basic urban parameters that in general have been studied separately: frstly the ‘urban political ecology', that is, the network of socio-ecological relationships within the city. Secondly, the 'economy of visibility', that is, the way the visible and invisible spheres are structured in relation with the governance frameworks. The intersection between the 'urban political ecology' and the 'economy of visibility' provides an effective analysis framework to understand the phenomenon of the 'opening of the black box'. It entails calling into question some of the predominant notions in classical urban and architectural theory, such as the segregation of nature, infrastructures and society, or the traditional forms of ecological usage of the environment. It also offers an exceptional analysis criterion to understand the discrediting process (from a philosophical, architectural, economic perspective, but also from the point of view of ecology, society, gender or queerness) of modern all-encompassing urban models that draw from the anthropocentric frameworks of the 19th century. Finally, it provides some architectural tools to tackle 21st-century ecosystemic challenges. The study of relevant authors that have analysed these problems for architecture, as well as the study of milestone architectural cases for the urban consolidation of processes associated to the 'black box', shall serve to reach the conclusion that, in ecological terms, modern cities have mobilised an 'urban political ecology' based on formulas of subjugation of the environment, through invisible architectural and technological operations. This thesis shall present an evaluation of whether the phenomenon of the 'opening of the black box' can be considered a symptom of the alteration of the 'urban political ecology'. We shall 'open the black box' to study the integration of the various urbanscale technological devices within the urban landscape, now that they have ceased to be invisible. We shall see how they participate, like any other actor, in the confguration of other cohabitation frameworks within today's cities.

Implications of climate change for rice farming in the Doñana wetland (SW Spain)

Climate change impacts are expected to affect rice farming and wetlands welfare in the Doñana protected Area, due to decreases in quantity and quality water supply and higher temperatures. The largest rice farming area is closely located to the Doñana wetlands in the Guadalquivir river basin estuary (South Western of Spain).
