Identifying Areas for Field Conservation of Forages in Latin American Disturbed Environments Ecology and Society
Peters, Michael; CIAT (International Center for Tropical Agriculture); m.peters-ciat@cgiar.org; Hyman, Glenn; CIAT (International Center for Tropical Agriculture); g.hyman@cgiar.org; Jones, Peter; CIAT (International Center for Tropical Agriculture); p.jones@cgiar.org.
This paper uses the spatial analysis tools DIVA and FloraMap to identify potential areas for the in situ conservation of a set of 10 forage species. We introduce the idea of roadside verges as conservation areas and discuss the risks and opportunities of two potential scenarios for conservation. These are the introduction of mass reservoirs outside of the original areas of collection and conservation inside the area of origin. Four potential areas for in situ conservation in Latin America are identified. Although more detailed studies using remote sensing, soil information, and field reconnaissance will be necessary for a final assessment of the suggested areas as field conservation sites, we discuss the possibilities of establishing low-maintenance...

The Social and Environmental Impacts of Biofuel Feedstock Cultivation: Evidence from Multi-Site Research in the Forest Frontier Ecology and Society
German, Laura; Center for International Forestry Research (CIFOR); L.GERMAN@cgiar.org; Schoneveld , George C.; Center for International Forestry Research (CIFOR); G.Schoneveld@cgiar.org; Pacheco, Pablo; Center for International Forestry Research (CIFOR); p.pacheco@cgiar.org.
Preoccupation with global energy supplies and climate change in the global North, and a desire to improve the balance of trade and capture value in the emerging carbon market by developing countries, together place biofuels firmly on the map of global land use change. Much of this recent land use change is occurring in developing countries where large agro-ecologically suitable tracts of land may be accessed at lower economic and opportunity cost. This is leading to the gradual penetration of commercial crops that provide suitable biofuel feedstocks (e.g., sugarcane, soybean, oil palm, jatropha) into rural communities and forested landscapes throughout many areas of the global South. Expansion of biofuel feedstock cultivation in developing countries is...

We provide a synthesis of what regional scientific research networks in less developed regions of the world can do and why they might be relevant for societal decisions and practice. We do so through a focus on three regional science network initiatives that aim to enhance understanding of the multiscalar dynamics of global environmental change (GEC) regionally and globally, namely the Southern Africa Regional Science Initiative (SAFARI 2000), the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), and the Inter-American Institute for Global Change (IAI). With a view to aiding future efforts at regional research network formation, we assess whether and how these three networks enhanced regional science, and the extent to which they sought and...

Impacts of Unsustainable Mahogany Logging in Bolivia and Peru Ecology and Society
Kometter, Roberto F; Universidad Nacional Agraria La Molina; kometter@lamolina01.lamolina.edu.pe; Martinez, Martha; Center for Applied Biodiversity Science, Conservation International; m.martinez@conservation.org; Blundell, Arthur G; EGAT Forest Team, USAID; art.blundell@alum.dartmouth.org; Gullison, Raymond E; Hardner & Gullison Associates; ted@hg-llc.com; Steininger, Marc K; Center for Applied Biodiversity Science, Conservation International; m.steininger@conservation.org; Rice, Richard E; Center for Applied Biodiversity Science, Conservation International; d.rice@conservation.org.
Although bigleaf mahogany [Swietenia macrophylla King (Meliaceae)] is the premier timber species of Latin America, its exploitation is unsustainable because of a pattern of local depletion and shifting supply. We surveyed experts on the status of mahogany in Bolivia and Peru, the world's past and present largest exporters. Bolivia no longer has commercially viable mahogany (trees > 60 cm diameter at breast height) across 79% of its range. In Peru, mahogany's range has shrunk by 50%, and, within a decade, a further 28% will be logged out. Approximately 15% of the mahogany range in these two countries is protected, but low densities and illegal logging mean that this overestimates the extent of mahogany under protection. The international community...

Globalization and Land-Use Transitions in Latin America Ecology and Society
Grau, H. Ricardo; Universidad Nacional de Tucuman; CONICET; chilograu@gmail.com; Aide, Mitchell; University of Puerto Rico; tmaide@yahoo.com.
Current socioeconomic drivers of land-use change associated with globalization are producing two contrasting land-use trends in Latin America. Increasing global food demand (particularly in Southeast Asia) accelerates deforestation in areas suitable for modern agriculture (e.g., soybean), severely threatening ecosystems, such as Amazonian rain forests, dry forests, and subtropical grasslands. Additionally, in the coming decades, demand for biofuels may become an emerging threat. In contrast, high yields in modern agricultural systems and rural–urban migration coupled with remittances promote the abandonment of marginal agricultural lands, thus favoring ecosystem recovery on mountains, deserts, and areas of poor soils, while improving human...

Assessing the Sustainability of Small Farmer Natural Resource Management Systems. A Critical Analysis of the MESMIS Program (1995-2010) Ecology and Society
Sustainability assessment oriented to improve current systems and practices is urgently needed, particularly in the context of small farmer natural resource management systems (NRMS). Unfortunately, social-ecological systems (SES) theory, sustainability evaluation frameworks, and assessment methods are still foreign not only to farmers but to many researchers, students, NGOs, policy makers/operators, and other interested groups. In this paper we examine the main achievements and challenges of the MESMIS Program (Spanish acronym for Indicator-based Sustainability Assessment Framework), a 15-year ongoing effort with impact in 60 case studies and 20 undergraduate and graduate programs mainly in Ibero-America that is attempting to cope with the stated...

Land-use regime shifts: an analytical framework and agenda for future land-use research Ecology and Society
Ramankutty, Navin; Liu Institute for Global Issues; Institute for Resources, Environment, and Sustainability, University of British Columbia; navin.ramankutty@ubc.ca; Coomes, Oliver T.; Department of Geography, McGill University; oliver.coomes@mcgill.ca.
A key research frontier in global change research lies in understanding processes of land change to inform predictive models of future land states. We believe that significant advances in the field are hampered by limited attention being paid to critical points of change termed land-use regime shifts. We present an analytical framework for understanding land-use regime shifts. We survey historical events of land change and perform in-depth case studies of soy and shrimp development in Latin America to demonstrate the role of preconditions, triggers, and self-reinforcing processes in driving land-use regime shifts. Whereas the land-use literature demonstrates a good understanding of within-regime dynamics, our understanding of the drivers of land-use regime...

Design and Analysis of Conservation Projects in Latin America: an Integrative Approach to Training Ecology and Society
Galindo-Leal, Carlos; Center for Applied Biodiversity Science, Conservation International; C.GALINDO@CONSERVATION.ORG.
The Latin American countries have a disproportionate importance in global biodiversity conservation. Six of the 14 megadiversity countries that house 60–70% of the species in the world are located on this region. Unfortunately, the number of environmental professionals in Latin America is extremely small. Furthermore, most of them have no postgraduate degrees and are unacquainted with general research methodology and recently developed concepts and tools. In addition, many speak no English and have no way to communicate with colleagues in other parts of the world. In collaboration with Latin American colleagues, universities, government agencies, and nongovernment organizations, I have been developing an integrated field course titled "Design and...

The role of cooperation for improved stewardship of marine social-ecological systems in Latin America Ecology and Society
Latin American and Caribbean (LAC) countries are among the worlds’ richest in marine biodiversity. Fish stocks in these regions are important for fishing communities, and fishing activities engage several million people. These fisheries depend on the natural services provided by a diverse range of marine social-ecological systems, but many LAC fisheries are in a degraded state, and concerns about overexploitation are widespread. With most fishery resources fully exploited or overexploited, opportunities for development lie primarily in restoring depleted stocks and using stocks more efficiently. The papers published in the Special Feature “Cooperation, Local Communities, and Marine Social-Ecological Systems: New Findings from Latin...

Toward Integrated Analysis of Human Impacts on Forest Biodiversity: Lessons from Latin America Ecology and Society
Newton, Adrian C; Centre for Conservation Ecology and Environmental Change, Bournemouth University; anewton@bournemouth.ac.uk; Golicher, Duncan; El Colegio de la Frontera Sur; dgoliche@sclc.ecosur.mx; Gonzalez-Espinosa, Mario; ECOSUR; mgonzale@ecosur.mx; Huth, Andreas; UFZ; andreas.huth@ufz.de; Premoli, Andrea; Universidad Nacional del Comahue; andrea.premoli@gmail.com.
Although sustainable forest management (SFM) has been widely adopted as a policy and management goal, high rates of forest loss and degradation are still occurring in many areas. Human activities such as logging, livestock husbandry, crop cultivation, infrastructural development, and use of fire are causing widespread loss of biodiversity, restricting progress toward SFM. In such situations, there is an urgent need for tools that can provide an integrated assessment of human impacts on forest biodiversity and that can support decision making related to forest use. This paper summarizes the experience gained by an international collaborative research effort spanning more than a decade, focusing on the tropical montane forests of Mexico and the temperate...

Meanings, drivers, and motivations for community-based conservation in Latin America Ecology and Society
Schunko, Christoph; Department of Sustainable Agricultural Systems, University of Natural Resources and Life Sciences (BOKU); christoph.schunko@boku.ac.at; Corbera, Esteve; Institute of Environmental Science and Technology (ICTA), Universitat Autònoma de Barcelona; Department of Economics and Economic History, Universitat Autònoma de Barcelona; esteve.corbera@uab.cat.
Indigenous and rural communities have developed strategies aimed at supporting their livelihoods and protecting biodiversity. Motivational factors underlying these local conservation strategies, however, are still a largely neglected topic. We aimed to enrich the conceptualization of community-based conservation by exploring trigger events and motivations that induce local people to be engaged in practical institutional arrangements for successful natural resource management and biodiversity conservation. By examining the history and development of three community conservation initiatives in Brazil, Mexico, and Bolivia, we have illustrated and discussed two main ways of understanding community-based conservation from the interaction between extrinsic and...

Conservation narratives in Peru: envisioning biodiversity in sustainable development Ecology and Society
In the mega-diverse country Peru, a resource intensive development model collides with the interest of conserving biodiversity. Peruvian biodiversity experts have developed different lines of argumentation as to how to integrate conservation into the sustainable development of their country. Applying grounded theory, I define five groups of conservation narratives based on the analysis of 72 qualitative interviews with experts working in areas of biodiversity conservation. I have labeled them: biodiversity protectionists, biodiversity traditionalists, biodiversity localists, biodiversity pragmatists, and biodiversity capitalists. These groups are each discussed in connection with what they have to say about biodiversity in relation to human life,...

Forest Landscape Restoration in the Drylands of Latin America Ecology and Society
Newton, Adrian C; Bournemouth University, Bournemouth, UK; anewton@bournemouth.ac.uk; Premoli, Andrea C; Laboratorio Ecotono, Universidad Nacional del Comahue, Bariloche, Argentina; andrea.premoli@gmail.com.
Forest Landscape Restoration (FLR) involves the ecological restoration of degraded forest landscapes, with the aim of benefiting both biodiversity and human well-being. We first identify four fundamental principles of FLR, based on previous definitions. We then critically evaluate the application of these principles in practice, based on the experience gained during an international, collaborative research project conducted in six dry forest landscapes of Latin America. Research highlighted the potential for FLR; tree species of high socioeconomic value were identified in all study areas, and strong dependence of local communities on forest resources was widely encountered, particularly for fuelwood. We demonstrated that FLR can be achieved through both...

Adapting prospective structural analysis to strengthen sustainable management and capacity building in community-based natural resource management contexts Ecology and Society
Local communities collectively managing common pool resources can play an important role in sustainable management, but they often lack the skills and context-specific tools required for such management. The complex dynamics of social-ecological systems (SES), the need for management capacities, and communities’ limited empowerment and participation skills present challenges for community-based natural resource management (CBNRM) strategies. We analyzed the applicability of prospective structural analysis (PSA), a strategic foresight tool, to support decision making and to foster sustainable management and capacity building in CBNRM contexts and the modifications necessary to use the tool in such contexts. By testing PSA in three SES in Colombia,...

This is the first of a series of papers that review the state of knowledge and practice regarding compensation and rewards for environmental services in the developing world. The paper begins with an assessment of the historical development of compensation and reward mechanisms within a broader context of changing approaches to nature conservation and environmental policy. The assessment shows that greater interest in compensation and reward mechanisms has emerged within a policy context of changing approaches to nature conservation and flexible multi-stakeholder approaches to environmental management. In the developing world, an even greater variety of perspectives has emerged on the opportunities and threats for using compensation and rewards for...

Interethnic admixture and the evolution of Latin American populations Genet. Mol. Biol.
Salzano,Francisco Mauro; Sans,Mónica.
A general introduction to the origins and history of Latin American populations is followed by a systematic review of the data from molecular autosomal assessments of the ethnic/continental (European, African, Amerindian) ancestries for 24 Latin American countries or territories. The data surveyed are of varying quality but provide a general picture of the present constitution of these populations. A brief discussion about the applications of these results (admixture mapping) is also provided. Latin American populations can be viewed as natural experiments for the investigation of unique anthropological and epidemiological issues.
