Mountain ecosystems are highly sensitive to global change. In fact, the continued capacity of mountain regions to provide goods and services to society is threatened by the impact of environmental changes on ecosystems. Although mapping ecosystem services values is known to support sustainable resource management, the integration of spatially explicit local expert knowledge on ecosystem dynamics and social responses to global changes has not yet been integrated in the modeling process. This contribution demonstrates the importance of integrating local knowledge into the spatially explicit valuation of ecosystem services. Knowledge acquired by expert surveys flows into a GIS-based Bayesian Network for valuing forest ecosystem services under a land-use and a...

The effects of land abandonment on biodiversity have received considerable attention by scholars, but results are far from conclusive. Different cultural traditions of scientists seem to underlie the contrasting ways in which land abandonment is understood. Although the forest transition (FT) framework considers land abandonment as an opportunity for biodiversity conservation, European landscape ecologists characterize it as a threat. We use insights from both traditions to analyze the effects of land abandonment on landscape and biodiversity in a mountain area of metropolitan Barcelona. We do so through an in-depth historical case study covering a period of 160 years. A set of landscape metrics was applied to land-cover maps derived from cadastral...

Causes and Extent of Declines among Native North American Invertebrate Pollinators: Detection, Evidence, and Consequences
Provedor de dados: Ecology and Society
Autores: Cane, James H; USDA-ARS; jcane@biology.usu.edu; Tepedino, Vincent J; USDA-ARS; andrena@biology.usu.edu.
Ecosystem health and agricultural wealth in North America depend on a particular invertebrate fauna to deliver pollination services. Extensive losses in pollinator guilds and communities can disrupt ecosystem integrity, a circumstance that today forces most farmers to rely on honey bees for much fruit and seed production. Are North America's invertebrate pollinator faunas already widely diminished or currently threatened by human activities? How would we know, what are the spatiotemporal scales for detection, and which anthropogenic factors are responsible? Answers to these questions were considered by participants in a workshop sponsored by the National Center for Ecological Analysis and Synthesis in October of 1999, and these questions form the nucleus...

Landscape Patterns of Exurban Growth in the USA from 1980 to 2020
Provedor de dados: Ecology and Society
Autores: Theobald, David M; Colorado State University; davet@nrel.colostate.edu.
In the United States, citizens, policy makers, and natural resource managers alike have become concerned about urban sprawl, both locally and nationally. Most assessments of sprawl, or undesired growth patterns, have focused on quantifying land-use changes in urban and metropolitan areas. It is critical for ecologists to examine and improve understanding of land-use changes beyond the urban fringe&amp;#8212;also called exurban sprawl&amp;#8212;because of the extensive and widespread changes that are occurring, and which often are located adjacent to or nearby &amp;#8220;protected&amp;#8221; lands.   The primary goal of this paper is to describe the development of a nationwide, fine-grained database of historical, current, and forecasted housing density,...

The use of science-based tools for impact assessment has increasingly gained focus in addressing the complexity of interactions between environment, society, and economy. For integrated assessment of policies affecting land use, an analytical framework was developed. The aim of our work was to apply the analytical framework for specific scenario cases and in combination with quantitative and qualitative application methods. The analytical framework was tested for two cases involving the ex ante impact assessment of: (1) a European Common Agricultural Policy (CAP) financial reform scenario employing a modeling approach and combined with a comprehensive indicator analysis and valuation; and (2) a regional bioenergy policy scenario, employing a fully...

Long-Term Forest Dynamics and Land-Use Abandonment in the Mediterranean Mountains, Corsica, France
Provedor de dados: Ecology and Society
Autores: Mouillot, Florent; DREAM CEFE/CNRS, France;.
Human practices have had an impact on Mediterranean ecosystems for millennia, particularly through agricultural and pastoral activities. Since the mid-19th century, land-use abandonment has led to the expansion of shrubland and forest, especially in the mountainous areas of the northern Mediterranean basin. Knowledge of these factors is vital to understanding present forest patterns and predicting future forest dynamics in the Mediterranean mountains. We aimed to analyze and understand how land-use abandonment affected spatial modifications of landscapes in two study areas, 44,000 ha and 60,000 ha, located on the island of Corsica, France, representing a typical Mediterranean environment with chestnut forests. Our approach used land-cover archive documents...

Autores: 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&amp;#8211;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...

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...

Conversions of natural ecosystems, e.g., from rain forests to managed plantations, result in significant changes in the hydrological cycle including periodic water scarcity. In Indonesia, large areas of forest were lost and extensive oil palm plantations were established over the last decades. We conducted a combined social and environmental study in a region of recent land-use change, the Jambi Province on Sumatra. The objective was to derive complementary lines of arguments to provide balanced insights into environmental perceptions and eco-hydrological processes accompanying land-use change. Interviews with villagers highlighted concerns regarding decreasing water levels in wells during dry periods and increasing fluctuations in stream flow between...

Mountain regions provide essential ecosystem goods and services (EGS) for both mountain dwellers and people living outside these areas. Global change endangers the capacity of mountain ecosystems to provide key services. The Mountland project focused on three case study regions in the Swiss Alps and aimed to propose land-use practices and alternative policy solutions to ensure the provision of key EGS under climate and land-use changes. We summarized and synthesized the results of the project and provide insights into the ecological, socioeconomic, and political processes relevant for analyzing global change impacts on a European mountain region. In Mountland, an integrative approach was applied, combining methods from economics and the political and...

The Value of Tropical Forest to Local Communities: Complications, Caveats, and Cautions
Provedor de dados: Ecology and Society
Autores: Sheil, Douglas; CIFOR (Center for International Forestry Research); d.sheil@cgiar.org; Wunder, Sven; CIFOR  (Center for International Forestry Research); S.Wunder@cgiar.org.
The methods used to value tropical forests have the potential to influence how policy makers and others perceive forest lands. A small number of valuation studies achieve real impact. These are generally succinct accounts supporting a specific perception. However, such reports risk being used to justify inappropriate actions. The end users of such results are rarely those who produced them, and misunderstanding of key details is a concern. One defense is to ensure that shortcomings and common pitfalls are better appreciated by the ultimate users. In this article, we aim to reduce such risks by discussing how valuation studies should be assessed and challenged by users.  We consider two concise, high-profile valuation papers here, by Peters and colleagues...

Knowledge of the interplay between ecological and social influences in the context of land-use decision-making is sparse. To help fill this gap, we conducted participatory land-cover mapping in an indigenous territory of eastern Panama to identify factors that influenced household land-use decisions. The map illustrated a mosaic of land cover dominated by pasture. Primary discourse on influences from 35 semistructured interviews with landowners, women, and youth emphasized economic concerns, such as subsistence, and social-cultural factors, such as reticence to abandon traditional agriculture. Multivariate analysis showed that timing of family settlement helped determine proportion of forest cover, and place of origin helped determine proportion of short...

Agricultural watersheds are affected by changes in climate, land use, agricultural practices, and human demand for energy, food, and water resources. In this context, we analyzed the agricultural, urbanizing Yahara watershed (size: 1345 km&amp;#178;, population: 372,000) to assess its responses to multiple changing drivers. We measured recent trends in land use/cover and water quality of the watershed, spatial patterns of 10 ecosystem services, and spatial patterns and nestedness of governance. We developed scenarios for the future of the Yahara watershed by integrating trends and events from the global scenarios literature, perspectives of stakeholders, and models of biophysical drivers and ecosystem services.

Shifting cultivation systems, one of the most widely distributed forms of agriculture in the tropics, provide not only crops of cultural significance, but also medicinal, edible, ritual, fuel, and forage resources, which contribute to the livelihoods, health, and cultural identity of local people. In many regions across the globe, shifting cultivation systems are undergoing important changes, one of the most pervasive being a shortening of the fallow cycle. Although there has been much attention drawn to declines in crop yields in conjunction with reductions in fallow times, little if any research has focused on the dynamics of noncrop plant resources.   In this paper, we use a data set of 26 fields of the same age, i.e., ~1.5 yr, but differing in the...

Habitat Fragmentation and Native Bees: a Premature Verdict?
Provedor de dados: Ecology and Society
Autores: Cane, James H; USDA-ARS; jcane@biology.usu.edu.
Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find...

We examined how social-ecological factors in the land-change decision-making process influenced neighboring decisions and trajectories of alternative landscape ecologies. We decomposed individual landowner decisions to conserve or develop forests in the rapidly growing Charlotte, North Carolina, U.S. region, exposing and quantifying the effects of forest quality, and social and cultural dynamics. We tested the hypothesis that the intrinsic value of forest resources, e.g., cultural attachment to land, influence woodland owners&amp;#8217; propensity to sell. Data were collected from a sample of urban, nonindustrial private forest (U-NIPF) owners using an individualized survey design that spatially matched land-owner responses to the ecological and timber...

Mountain ecosystems provide a broad range of ecosystem services (ES). Trade-offs between different ES are an important aspect in the assessment of future sustainable land-use. Management of ES in mountain regions must confront the challenges of spatial and temporal heterogeneity, and interaction with structural changes in agriculture and forestry. Using a social-ecological modeling framework, we assess the relationships between forest and agricultural ES in a mountain region in Switzerland. Based on the concept of jointness in production, we evaluated trade-offs and synergies among food provision, biodiversity conservation, carbon sequestration, and protection against natural hazards. Results show that increasing the provision of a focal ES in a mountain...

A time to change? The supply of climate mitigation products from land-use change in northern NSW
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Moss,   Jonathan; Cacho,   Oscar J.; Mounter,   Stuart W.
With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers and landholders in rural Australia have increased opportunities to participate in the market. This includes the adoption of land-use change to sequester additional carbon in exchange for carbon credits and the production of a renewable energy source (biofuels). However, these land-use changes compete with existing farm enterprises and may contain significant transaction costs. Therefore it is necessary for the institutional arrangements to provide adequate incentives for landholders to adopt these land-use changes. This paper examines the potential supply of these land-use changes for climate mitigation from landholders in a northern NSW catchment. These results...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lubowski,   Ruben N.; Plantinga,   Andrew J.; Stavins,   Robert N.
When and if the United States chooses to implement a greenhouse gas reduction program, it will be necessary to decide whether carbon sequestration policies - such as those that promote forestation and discourage deforestation - should be part of the domestic portfolio of compliance activities. We investigate the cost of forest-based carbon sequestration. In contrast with previous approaches, we econometrically examine micro-data on revealed landowner preferences, modeling six major private land uses in a comprehensive analysis of the contiguous United States.

Towards an Integrated Global Agricultural Greenhouse Gas Model: Greenhouse Gases from Agriculture Simulation Model (GreenAgSiM)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dumortier,   Jerome; Hayes,   Dermot J.
The Greenhouse Gases from Agriculture Simulation Model (GreenAgSiM) presented in this paper aims to quantify emissions from agricultural activity on a global scale. The model takes emissions into account that are directly attributable to agricultural production, such as enteric fermentation (methane), manure management (methane and nitrous oxide), and agricultural soil management (nitrous oxide). Furthermore, carbon stock differences from land-use change (carbon dioxide) induced by agriculture are included in the model. The model will provide policy makers with information about the greenhouse gas implications of policy changes.

Autores: Lubowski,   Ruben N.; Bucholtz,   Shawn; Claassen,   Roger; Roberts,   Michael J.; Cooper,   Joseph C.; Gueorguieva,   Anna; Johansson,   Robert C.
This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity. If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced changes in land use could have production effects that are smaller-and environmental impacts that are greater-than anticipated. To illustrate this possibility, this report examines environmental outcomes stemming from landuse conversion caused by two agricultural programs that others have identified as potentially having important influences on land use and environmental quality: Federal crop insurance subsidies and the Conservation Reserve Program (CRP), the Nation's...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Race,   Digby; Farquharson,   Robert J.; Birckhead,   Jim; Vernon,   Don; Bathgate,   Andrew D.
Meshed with the bio-physical and economic dimensions of rural land-use is a social dimension. Understanding the social and economic dimension of rural communities is critical if agencies are to develop effective policies and programs to improve natural resource outcomes. In this paper, we draw on research of the Boorowa community, located in the south-west slopes of New South Wales, to help understand how social changes in rural communities are impacting natural resource management in the Boorowa district. This included: • *Identifying the catalysts for changing land-use in the Boorowa catchment, • *Presenting an effective and efficient methodology for assessing the social and economic impacts of changes in land use at the catchment scale, • *Identifying...

We present a global agricultural greenhouse gas model that assesses emissions from land-use change. In addition to evaluating shifts in and out of crop production, we develop a pasture model to assess extensification and intensification of global livestock production based on herd size and stocking rate. We apply the model to a scenario that introduces a tax on me-thane emissions from cattle in the United States. The resulting expansion of pasture in the rest of the world leads to substantially higher emissions than without the tax. The yearly average emissions from the tax are 260 metric tons of CO2-equivalent.

Predicting China’s Land-use Change and Soil Carbon Sequestration under Alternative Climate Change Scenarios
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Li,   Man; Wu,   JunJie.
This paper examines and predicts the effects of climate change and climate extremes on China’s land use conversion and soil carbon sequestration under two alternative climate change scenarios. It intends to investigate the following three questions. 1) How did climate factors affect land-use conversion in China from 1988 to 2000 and what was the relative importance of these factors? 2) How would the predicted future climate change pattern affect land-use choice under alternative climate change scenarios? 3) How would the predicted future climate pattern change the spatial distribution of soil organic carbon in China? The study makes two contributions to the literature. First, it integrates climate change, land use conversion, and soil carbon sequestration...

Economics of Smallholder Rubber Production in Northern Laos
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Manivong,   Vongpaphane; Cramb,   Rob A.
In response to demand from China, rubber smallholdings are being established by shifting cultivators in Northern Laos, encouraged by government land-use policy. We examine the economics of smallholder rubber production in an established rubbergrowing village and model the likely expansion of smallholder rubber in Northern Laos. Data were obtained from key informants, group interviews, direct observation, and a farm-household survey. Latex yields were estimated using the Bioeconomic Rubber Agroforestry Support System (BRASS). A financial model was developed to estimate the net present value for a representative rubber smallholding. This model was then combined with spatial data in a Geographical Information System (GIS) to predict the likely expansion of...

Geoecological drivers of cerrado heterogeneity and 13C natural abundance in oxisols after land-use change
Provedor de dados: Revista Brasileira de Ciência do Solo
Autores: Neufeldt,Henry.
The 13C natural abundance technique was applied to study C dynamics after land-use change from native savanna to Brachiaria, Pinus, and Eucalyptus in differently textured Cerrado Oxisols. But due to differences in the d13C signatures of subsoils under native savanna and under introduced species, C substitution could only be calculated based on results of cultivated soils nearby. It was estimated that after 20 years, Pinus C had replaced only 5 % of the native C in the 0-1.2 m layer, in which substitution was restricted to the top 0.4 m. Conversely, after 12 years, Brachiaria had replaced 21 % of Cerrado C to a depth of 1.2 m, where substitution decreased only slightly throughout the entire profile. The high d13C values in the subsoils of the cultivated...

Autores: Reis,Simone Matias; Lenza,Eddie; Marimon,Beatriz Schwantes; Gomes,Letícia; Forsthofer,Mônica; Morandi,Paulo Sérgio; Marimon Junior,Ben Hur; Feldpausch,Ted R.; Elias,Fernando.
ABSTRACTFire can change the species composition, diversity, and structure of savanna vegetation, thus altering growth and mortality rates. Such changes in the woody vegetation of burned savanna forest were evaluated over four years in comparison to unburned savanna forest. All woody plants with a diameter at breast height &gt; 10 cm were measured in 100 permanent plots. Six months later, 38 of these plots were burned. Three and a half years later, all surviving individuals were re-sampled. Species richness, diversity, and the number of individuals did not change in the burned plots, although they had significantly higher (p &lt; 0.05) increases in basal area and mortality rates (5.1% year-1) than the unburned plots (3.0% year-1).Tachigali vulgarishad the...
