“…In the United States, several states, including Washington, Oregon, Maine and Tennessee, have required all local governments to develop comprehensive plans that include urban growth boundaries. Given the considerable attention to the problems occurring as a result of urban sprawl (Batty, 2005; Van and Mahler, 2005;Verburg, 2006;Acevedo et al, 2007;He and Lo, 2007;, and the increasing attention given to UGBs as a regional planning tool, it is thus surprising that very little research has focused on developing models that assist planners in delineating the urban boundary (cf. Knaap and Hopkins, 2001).…”

“…According to Acevedo et al [49], deforestation and degradation in the CFR occurred in an intricate sequence of stages that often started with selective logging followed by the burning of remaining forests mostly for subsistence activities. Later on, large portions of the area were completely transformed to cattle grazing farms in which land tenure was ultimately transferred to private owners contrary to official regulations [50,51].…”

“…As shown by Asner et al [60] in some areas of the Amazon, forest degradation from logging has been a precursor of deforestation and these activities can be detected using Landsat images. In our study area, logging has been a fundamental force of forest degradation for a great portion of the period considered here [49,50]. Finally, one hectare (1 ha) was assumed as the minimum mapping unit (MMU), with the years of analysis classified as follows: 1990 was defined as the baseline or Year 0, Year 2000 as Year 1, 2010 as Year 2, and 2015 as Year 3.…”

This study presents for the first time in Venezuela a joint analysis of deforestation and forest degradation processes, including its effects on carbon emissions. The Caparo Forest Reserve, located in the Western Plains ecoregion, in one of the national hot spots of deforestation, served as a case study using three different periods: 1990-2000, 2000-2010 and 2010-2015. In the context of the United Nations Framework Convention on Climate Change (UNFCCC) framework, the Practice Guidance for Land Use, Land-Use Change and Forestry from the Intergovernmental Panel on Climate Change (IPCC) was followed. These guidelines combine the activity data for the estimation of deforestation and degradation rates, in this case using open access Landsat imagery in conjunction with the TerraAmazon system with the emission factors, and these based on aboveground biomass (AGB) estimations using field data from permanent plots monitored during the study period. Deforestation was responsible of a net loss of −53,461 ha, while close to −3667 ha were classified as degraded forests during the 1990-2000 decade (−4.9% annual deforestation rate). An estimated area of −36,447 ha and −515 ha between 2000 and 2010 was affected by both processes (−4.3% annual forest loss), and −8111 ha and −737 ha between 2010 and 2015 (−3.2% per year). These processes were responsible for an estimated equivalent in carbon emissions of 2.21 ± 0.32 (SEM-Standard Error of the Mean) Mt CO 2 year −1 (1990-2000), 1.56 ± 0.19 Mt CO 2 per year between 2000 and 2010, while 0.80 ± 0.11 Mt CO 2 year −1 during the 2010-2015 period. Between 92.9% and 98.63% (mean 94.9%) of these emissions came from deforestation, and between 1.37% and 7.79% (mean 5.1%) from forest degradation. Using available data, at national scale, deforestation and forest degradation in Caparo represented, on average, 0.49% of the total CO 2 emissions and about 1.79% of land use change related emissions for the same period in Venezuela. Finally, we briefly outline a set of elements so these results can serve as a baseline for the potential establishment of a Reducing Emissions from Deforestation and Forest Degradation (REDD+) strategy in the area.

“…An important type of land-use change model uses multi-agent methodology to couple values and attitudes of individuals and policy making in a socioecological model (Callicott et al 2007;Acevedo et al 2008;Le et al 2010). Multi-agent models allow simulations of human decision processes that include value systems or preferences based on surveys, focus groups and interviews, and can interact with natural system models, such as hydrologic models.…”

“…Strategies at the farm level are scaled-up to conduct landscape-level optimization, which feeds back to the agents to search for the best strategies. Although this proposal is ambitious, some experiences provide potential components and approaches (Bernknopf et al 2002;Acevedo et al 2008;Le et al 2010).…”

SUMMARYThis review examines contributions of interdisciplinary (ID) research to understanding interactions between environmental quality, food production and food security. Global patterns of food insecurity and crop production are reviewed in relation to climate, land use and economic changes, as well as potential productivity increases compatible with environmental conservation. Interactions between food production and global processes make food insecurity a complex problem that requires ID analysis at local to global scales. Census and satellite data contribute to understanding of global cropland distribution. Analysis of land-use change exemplifies research between natural and social sciences. Quantitative modelling of global climate change impacts indicates relatively greater potential food insecurity in developing countries. International food security is increasingly interconnected through economic globalization and incentives for increased food production are required. Societies may not be able to expand available cropland without significant environmental risks; enhanced land and water productivity are the major opportunities available to increase food production. This requires renewed efforts in ID work to design and implement sound and efficient agricultural management practices. Models need to be informed by data from field experiments, long-term measurements and watershed monitoring by ground and remote sensing methods. Agricultural intensification may spare natural land but lead to increased pollution and water demand; reconciling conservation and productivity is a critical need. ID work provides many opportunities for synergies including conservation agriculture at the local level, efficient use of inputs, smarter land use taking into account spatial patterns and landscape ecology principles, and improved water management at field, system, watershed and basin levels. Goal-directed ID research is crucial, since producers, practitioners and policy makers should be * Correspondence: Dr Miguel Acevedo e-mail: acevedo@unt.edu involved. Geospatial, biotechnological and precision agriculture technologies linked with models can help inform strategies to achieve sustainable food production increases that maintain environmental quality. Implementation also requires ID work to overcome impediments due to human factors and facilitate adoption by farmers.
