Education, Vulnerability, and Resilience after a Natural Disaster Ecology and Society
Frankenberg, Elizabeth; Duke University; e.frankenberg@duke.edu; Sikoki, Bondan; SurveyMeter; bsikoki@gmail.com; Sumantri, Cecep; SurveyMeter; sumantri.2011@gmail.com; Suriastini, Wayan; SurveyMeter; suriastini@gmail.com; Thomas, Duncan; Duke University; d.thomas@duke.edu.
The extent to which education provides protection in the face of a large-scale natural disaster is investigated. Using longitudinal population-representative survey data collected in two provinces on the island of Sumatra, Indonesia, before and after the 2004 Indian Ocean tsunami, we examine changes in a broad array of indicators of well-being of adults. Focusing on adults who were living, before the tsunami, in areas that were subsequently severely damaged by the tsunami, better educated males were more likely to survive the tsunami, but education is not predictive of survival among females. Education is not associated with levels of post-traumatic stress among survivors 1 year after the tsunami, or with the likelihood of being displaced. Where education...

Balancing Development and Conservation? An Assessment of Livelihood and Environmental Outcomes of Nontimber Forest Product Trade in Asia, Africa, and Latin America Ecology and Society
Kusters, Koen; Center for International Forestry Research (CIFOR); k.kusters@cgiar.org; Achdiawan, Ramadhani; Center for International Forestry Research (CIFOR); r.achdiawan@cgiar.org; Belcher, Brian; Center for International Forestry Research (CIFOR); b.belcher@cgiar.org.
This article addresses the question, to what extent and under which conditions nontimber forest product (NTFP) trade leads to both livelihood improvement and forest conservation. We based the analysis on a standardized expert-judgment assessment of the livelihood and environmental outcomes of 55 cases of NTFP trade from Asia, Africa, and Latin America. The results show that NTFP trade benefits several components of peoples' livelihoods, but may increase inequality between households. Involvement of women in the production-to-consumption system (PCS) tends to have a positive impact on intrahousehold equity. In 80% of the cases, the commercial production of NTFPs does not enable people to make financial investments to increase quality and quantity of...

Anticipatory Learning for Climate Change Adaptation and Resilience Ecology and Society
Tschakert, Petra; Department of Geography; Earth and Environmental Systems Institute (EESI), Pennsylvania State University; petra@psu.edu; Dietrich, Kathleen Ann; Department of Geography, Pennsylvania State University; kad984@psu.edu.
This paper is a methodological contribution to emerging debates on the role of learning, particularly forward-looking (anticipatory) learning, as a key element for adaptation and resilience in the context of climate change. First, we describe two major challenges: understanding adaptation as a process and recognizing the inadequacy of existing learning tools, with a specific focus on high poverty contexts and complex livelihood-vulnerability risks. Then, the article examines learning processes from a dynamic systems perspective, comparing theoretical aspects and conceptual advances in resilience thinking and action research/learning (AR/AL). Particular attention is paid to learning loops (cycles), critical reflection, spaces for learning, and power....

The literature on drought, livelihoods, and poverty suggests that dryland residents are especially vulnerable to climate change. However, assessing this vulnerability and sharing lessons between dryland communities on how to reduce vulnerability has proven difficult because of multiple definitions of vulnerability, complexities in quantification, and the temporal and spatial variability inherent in dryland agroecological systems. In this closing editorial, we review how we have addressed these challenges through a series of structured, multiscale, and interdisciplinary vulnerability assessment case studies from drylands in West Africa, southern Africa, Mediterranean Europe, Asia, and Latin America. These case studies adopt a common vulnerability framework...

Private protected area (PPA) conservation agents (CA) engaging in development-based conservation in southern Chile have generated conflict with locals. Poor fit of dominant development-based conservation ideology in rural areas is commonly to blame. We developed and administered a cultural consensus survey near the Valdivian Coastal Reserve (RCV) and Huilo Huilo Reserve (HH) to examine fit of CA cultural truths with local residents. Cultural consensus analysis (CCA) of 23 propositions reflecting CA cultural truths confirmed: (1) a single CA culture exists, and (2) RCV communities were more aligned with this culture than HH communities. Inadequate communication, inequitable decision making, divergent opinions about livelihood impacts and trajectories, and...

Navigating trade-offs in land-use planning: integrating human well-being into objective setting Ecology and Society
Adams, Vanessa M.; Research Institute for the Environment and Livelihoods, Charles Darwin University; Australian Research Council Centre of Excellence for Coral Reef Studies, James Cook University; National Environmental Research Program Northern Australia Hub; v.adams@uq.edu.au; Pressey, Robert L.; Australian Research Council Centre of Excellence for Coral Reef Studies, James Cook University; National Environmental Research Program Northern Australia Hub; Bob.pressey@jcu.edu.au; Stoeckl, Natalie; School of Business and Cairns Institute, James Cook University; National Environmental Research Program Northern Australia Hub; natalie.stoeckl@jcu.edu.au.
There is an increasing demand for development of natural resources, which can be accompanied by environmental degradation. Planning for multiple land uses requires navigating trade-offs between social, economic, and environmental outcomes arising from different possible futures. To explore these trade-offs, we use the Daly River catchment, in Australia’s Northern Territory, as a case study. The catchment contains areas of priority for both conservation and development. In response to the challenge of navigating the required trade-offs, the Daly River Management Advisory Committee (DRMAC) initiated a land-use plan for the region. Both development and conservation of natural resources in the catchment will affect human well-being and the...

Navigating the adaptive cycle: an approach to managing the resilience of social systems Ecology and Society
Fath, Brian D; Advanced Systems Analysis, International Institute for Applied Systems Analysis; Department of Biological Sciences, Towson University; bfath@towson.edu; Dean, Carly A; Advanced Systems Analysis, International Institute for Applied Systems Analysis; carly.ann.dean@gmail.com; Katzmair, Harald; FAS.research; harald.katzmair@fas.at.
The concept of resilience continues to crescendo since the 1990s, touching on multiple fields with multiple interpretations and uses. Here, we start from its origins in systems ecology, framing the resilience concept explicitly in the adaptive cycle with the observation that resilient systems are ones that successfully navigate all stages of growth, development, collapse, and reorientation of this cycle. The model is explored in terms of the traps and pathologies that hinder this successful navigation, particularly when applied to socioeconomic organizations and decision-management situations. For example, for continuous function over the adaptive life cycle, a system needs activation energy or resources to grow, followed by adequate structure and...

We applied an integrative framework to illuminate and discuss the complexities of exurbanization in Macon County, North Carolina. The case of Macon County, North Carolina, highlights the complexity involved in addressing issues of exurbanization in the Southern Appalachian region. Exurbanization, the process by which urban residents move into rural areas in search of unique natural amenities and idealized lifestyles, can often have a dramatic impact on the local economy, culture, and environment. Within Macon County, complex debates and tensions among multiple stakeholders struggle to address local residential development. How can better problem definition benefit rural communities in addressing exurbanization pressures and effects? We asserted that a key...

Conservation and Unscripted Development: Proximity to Park Associated with Development and Financial Diversity Ecology and Society
Baird, Timothy D.; Virginia Tech; tbaird@vt.edu.
Decades of research on the social dynamics of biodiversity conservation has shown that parks and protected areas have added hardship to rural communities throughout much of the developing world. Nonetheless, some recent studies have found evidence of poverty alleviation near protected areas. To build on these conflicting accounts, I use a comparative, mixed-methods design to examine opportunistic, unplanned, i.e., unscripted, development in indigenous communities near Tarangire National Park (TNP) in northern Tanzania. I ask the questions: (1) How is proximity to TNP related to community-level infrastructural development? (2) How has the process of development changed over time? and (3) How is proximity to TNP related to infrastructure-related social...

Rights for resilience: food sovereignty, power, and resilience in development practice Ecology and Society
Walsh-Dilley, Marygold; Honors College, University of New Mexico; marygoldwd@unm.edu; Wolford, Wendy; Department of Development Sociology, Cornell University; www43@cornell.edu; McCarthy, James; Graduate School of Geography, Clark University; jamccarthy@clarku.edu.
Even as resilience thinking becomes evermore popular as part of strategic programming among development and humanitarian organizations, uncertainty about how to define, operationalize, measure, and evaluate resilience for development goals prevails. As a result, many organizations and institutions have undertaken individual, collective, and simultaneous efforts toward clarification and definition. This has opened up a unique opportunity for a rethinking of development practices. The emergent consensus about what resilience means within development practice will have important consequences both for development practitioners and the communities in which they work. Incorporating resilience thinking into development practice has the potential to radically...

The Role of Governance in Agricultural Expansion and Intensification: a Global Study of Arable Agriculture Ecology and Society
Mandemaker, Menno; Chairgroup of Land Dynamics, Wageningen University; menno.mandemaker@wur.nl; Bakker, Martha; Chairgroup of Land Dynamics, Wageningen University; Martha.bakker@wur.nl; Stoorvogel, Jetse; Chairgroup of Land Dynamics, Wageningen University; jetse.stoorvogel@wur.nl.
In this research we studied empirical relationships between agricultural production dynamics and six quantitative World Bank governance indicators for 173 countries between 1975 and 2007. It is hypothesized that in countries with lower quality of governance, agricultural production increases are more likely to be achieved by area expansions than by increases in yields. We distinguished four groups of countries: those with both area and yield increases; those with increasing yields but decreasing area; those with decreasing yields but a growing area; and those with both declines in yields and area. We analyzed differences between these four groups, and also analyzed governance-production relationships within these groups. On average, quality of governance...

In 2014, the Third International Conference on the resilience of social-ecological systems chose the theme “resilience and development: mobilizing for transformation.” The conference aimed specifically at fostering an encounter between the experiences and thinking focused on the issue of resilience through a social and ecological system perspective, and the experiences focused on the issue of resilience through a development perspective. In this perspectives piece, we reflect on the outcomes of the meeting and document the differences and similarities between the two perspectives as discussed during the conference, and identify bridging questions designed to guide future interactions. After the conference, we read the documents...

Policy and investment decisions in highly connected, developing regions can have implications that extend beyond their initial objectives of national development and poverty reduction. Local level decisions that aim to promote trajectories toward desirable futures are often transformative, unexpectedly altering factors that are determined at higher regional levels. The converse also applies. The ability to realize desirable local futures diminishes if decision-making processes are not coordinated with other influential governance and decision levels. Providing effective support across multiple levels of decision making in a connected, transformative environment requires (a) identification and articulation of desired outcomes at the relevant levels of...

Infodynamics, a Developmental Framework for Ecology/Economics Ecology and Society
Salthe, Stanley N; Biological Sciences, Binghamton University; ssalthe@binghamton.edu.
Infodynamics, for our purposes, is a developmental perspective that animates information theory by way of thermodynamics. The isomorphism between Boltzmann's statistical interpretation of physical entropy as disorder and Shannon's formulation of variety as informational entropy signals a deep connection between information and entropy production. Information is any configuration that might have been different, providing that it delays energy dissipation so that the energy is dissipated more completely. The entropy production of individual dissipative structures increases at first but eventually decelerates. I consider the questions: why do these structures grow? And why don't they keep on growing? As the universal expansion of the Big Bang accelerated,...

THE SUCCESS OF THE BRAZILIAN ALCOHOL PROGRAM (PROÁLCOOL) - A DECADE-BY-DECADE BRIEF HISTORY OF ETHANOL IN BRAZIL REA
Stolf,Rubismar; Oliveira,Ana Paula Rodrigues de.
ABSTRACT The National Alcohol Program (Proálcool) was a strategic policy of the Brazilian government to replace petroleum-based fuels with alcohol (ethanol). Based on the review, we can choose the 1960s as a start point for a leap in development. Over the 500 years of sugarcane history in Brazil, the crop enters the second decade of the 21st century with extraordinary strength and prestige, reaching its highest production in history. This made Brazil a leader in sugar and ethanol productions worldwide, with an energy-independent agribusiness. Moreover, effluents and polluting wastes were transformed into high-value inputs (e.g., vinasse, filter cake, and others). Environmentally friendly actions included developing organic cane production technology,...

Sex determination in annual fishes: searching for the master sex-determining gene in Austrolebias charrua (Cyprinodontiformes, Rivulidae) Genet. Mol. Biol.
Arezo,María José; Papa,Nicolás; Guttierrez,Verónica; García,Graciela; Berois,Nibia.
Evolution of sex determination and differentiation in fishes involves a broad range of sex strategies (hermaphroditism, gonochorism, unisexuality, environmental and genetic sex determination). Annual fishes inhabit temporary ponds that dry out during the dry season when adults die. The embryos exhibit an atypical developmental pattern and remain buried in the bottom mud until the next rainy season. To elucidate genomic factors involved in the sex determination in annual fish, we explored the presence of a candidate sex-specific gene related to the cascade network in Austrolebias charrua. All phylogenetic analyses showed a high posterior probability of occurrence for a clade integrated by nuclear sequences (aprox. 900 bp) from both adults (male and female),...

A Floricaula/Leafy gene homolog is preferentially expressed in developing female cones of the tropical pine Pinus caribaea var. caribaea Genet. Mol. Biol.
Dornelas,Marcelo Carnier; Rodriguez,Adriana Pinheiro Martinelli.
In angiosperms, flower formation is controlled by meristem identity genes, one of which, FLORICAULA (FLO)/LEAFY (LFY), plays a central role. It is not known if the formation of reproductive organs of pre-angiosperm species is similarly regulated. Here, we report the cloning of a conifer (Pinus caribaea var. caribaea) FLO/LFY homolog, named PcLFY. This gene has a large C-terminal region of high similarity to angiosperm FLO/LFY orthologs and shorter regions of local similarity. In contrast to angiosperms, conifers have two divergent genes resembling LFY. Gymnosperm FLO/LFY proteins constitute a separate clade, that can be divided into two divergent groups. Phylogenetic analysis of deduced protein sequences has shown that PcLFY belongs to the LFY-like clade....

Towards the identification of flower-specific genes in Citrus spp Genet. Mol. Biol.
Dornelas,Marcelo Carnier; Camargo,Raquel Luciana Boscariol; Berger,Irving Joseph; Takita,Marco Aurélio.
Citrus sinensis is a perennial woody species, for which genetic approaches to the study of reproductive development are not readily amenable. Here, the usefulness of the CitEST Expressed Sequence Tag (EST) database is demonstrated as a reliable new resource for identifying novel genes exclusively related to Citrus reproductive biology. We performed the analysis of an EST dataset of the CitEST Project containing 4,330 flower-derived cDNA sequences. Relying on bioinformatics tools, sequences exclusively present in this flower-derived sequence collection were selected and used for the identification of Citrus putative flower-specific genes. Our analysis revealed several Citrus sequences showing significant similarity to conserved genes known to have...
