TL;DR: In this paper, the role of protected and community managed forests for the long term maintenance of forest cover in the tropics was assessed through a meta-analysis of published case-studies, which compared land use/cover change data for these two broad types of forest management and assess their performance in maintaining forest cover.

TL;DR: The importance of local community forestry institutions towards forest conservation is exemplified through a comparison of two adjacent areas within the Central Yucatan Peninsular Region (CYPR) in which Land-Use Cover Change (LUCC) analyses were conducted as discussed by the authors.

TL;DR: In this article, the authors use Landsat images to demonstrate a low incidence of net deforestation, 0.01% for the 1984-2000 period, the lowest recorded deforestation rate for southeastern Mexico.

TL;DR: A change detection analysis of three satellite images was used to assess forest clearing for agriculture from two time periods (1988-2000 and 2000-2005) by interpreting remotely sensed satellite image data as discussed by the authors.

TL;DR: In this article, the authors present results on land use/land cover dynamics in the municipality of Zozocolco de Hidalgo from 1973 to 2006, and combine remote sensing and GIS analyses, binary logistic regression and econometric modeling, as well as socioeconomic surveys to evaluate land use and land cover change (LULCC) dynamics and explore potential environmental and socioeconomic drivers.
Abstract: In the state of Veracruz, Mexico, lowland and marginal coffee growing regions have been particularly vulnerable since the 1989 coffee crisis. Government programs have promoted production diversification as a strategy to improve local incomes and conserve environmentally beneficial shade-tree coffee agroforests. We present results on land use/land cover dynamics in the municipality of Zozocolco de Hidalgo from 1973 to 2006. The municipality is recognized for its indigenous population and poverty, and currently, diversification efforts are being implemented. Our study combines remote sensing and GIS analyses, binary logistic regression and econometric modeling, as well as socioeconomic surveys to evaluate land use/land cover change (LULCC) dynamics and explore potential environmental and socioeconomic drivers. Results show that tree cover and coffee agroforests had largely been conserved during the first decade after the coffee crisis. But, recent trends indicate loss of tree cover in coffee agroforests and their conversion mostly to pasture. Land use/land cover drivers are largely explained by spatially explicit environmental variables such as slope and elevation. Relevant socioeconomic variables such as distance to markets and land use profitability were not significantly related to land use changes in Zozocolco. Surveys revealed that many households had converted coffee agroforests to pasture or agriculture in the past decade and others intended on renting or selling their agroforest plots, mostly for conversion to pasture. Diversification programs may not be sufficient to stem deforestation in lowland and marginal coffee growing regions. Moreover, information about locally varying socioeconomic and cultural contexts needs to be strongly considered in order to formulate effective strategies.

TL;DR: The work of the IPCC Working Group III 5th Assessment report as mentioned in this paper is a comprehensive, objective and policy neutral assessment of the current scientific knowledge on mitigating climate change, which has been extensively reviewed by experts and governments to ensure quality and comprehensiveness.
Abstract: The talk with present the key results of the IPCC Working Group III 5th assessment report. Concluding four years of intense scientific collaboration by hundreds of authors from around the world, the report responds to the request of the world's governments for a comprehensive, objective and policy neutral assessment of the current scientific knowledge on mitigating climate change. The report has been extensively reviewed by experts and governments to ensure quality and comprehensiveness.

TL;DR: In this paper, the authors describe the intellectual journey that has taken the last half century from when they began graduate studies in the late 1950s to the development of the Institutional Analysis and Development (IAD) framework.
Abstract: Contemporary research on the outcomes of diverse institutional arrangements for governing common-pool resources (CPRs ) and public goods at multiple scales builds on classical economic theory while developing new theory to explain phenomena that do not fit in a dichotomous world of “the market” and “the state.” Scholars are slowly shifting from positing simple systems to using more complex frameworks, theories, and models to understand the diversity of puzzles and problems facing humans interacting in contemporary societies. The humans we study have complex motivational structures and establish diverse private-for-profit, governmental, and com munity institutional arrangements that operate at multiple scales to generate productive and inno vative as well as destructive and perverse outcomes ( Douglass C. North 1990, 2005 ). In this article, I will describe the intellectual journey that I have taken the last half century from when I began graduate studies in the late 1950s. The early efforts to understand the poly centric water industry in California were formative for me. In addition to working with Vincent Ostrom and Charles M. Tiebout as they formulated the concept of polycentric systems for gov erning metropolitan areas, I studied the efforts of a large group of private and public water producers facing the problem of an overdrafted groundwater basin on the coast and watching saltwater intrusion threaten the possibility of long term use. Then, in the 1970s, I participated with colleagues in the study of polycentric police industries serving US metropolitan areas to find that the dominant theory underlying massive reform proposals was incorrect. Metropolitan areas served by a combination of large and small producers could achieve economies of scale in the production of some police services and avoid diseconomies of scale in the production of others. These early empirical studies led over time to the development of the Institutional Analysis and Development (IAD) framework. A common framework consistent with game theory enabled us to undertake a variety of empirical studies including a meta-analysis of a large number of existing case studies on common-pool resource systems around the world. Carefully designed experimental studies in the lab have enabled us to test precise combinations of structural vari ables to find that isolated, anonymous individuals overharvest from common-pool resources. Simply allowing communication, or “cheap talk,” enables participants to reduce overharvest ing and increase joint payoffs contrary to game theoretical predictions. Large studies of irrigation systems in Nepal and forests around the world challenge the presumption that governments always do a better job than users in organizing and protecting important resources.

TL;DR: In this article, the authors argue that the true value of functional biodiversity on the farm is often inadequately acknowledged or understood, while conventional intensification tends to disrupt beneficial functions of biodiversity.
