“…Our overall accuracies are acceptable for remote sensing analysis, especially considering the small size of our analysis area (7000 ha), since smaller classified surface areas tend to have greater misclassification errors than large surface areas classified using multispectral images such as LANDSAT and SPOT (http://rst.gsfc.nasa.gov/Sect 13/Sect13_3.html). Moreover, our overall accuracies are comparable to other remote sensing studies (Ellis and Porter-Bolland 2008;Muñoz-Villers and López-Blanco 2008;Wyman and Stein 2009).…”

“…Most households in Zozocolco involved in coffee production tended to conserve their agroforest parcels during this period despite the drastic decline of coffee prices. Other LULCC studies in the state of Veracruz also show that shade coffee plantations were mostly preserved in the following decade after the coffee crisis (Martínez et al 2009;Tucker et al 2009;Muñoz-Villers and López-Blanco 2008;Mestries Benquet 2003). Household surveys and interviews conducted in the municipality confirm this trend, indicating that many coffee farmers opted in not converting their agroforest parcel until the mid 1990s with the expectation of more favorable prices.…”

“…In contrast, coffee plantations cultivated without shade were converted to other uses such as sugar cane and pasture (Muñoz-Villers and López-Blanco 2008). Another study in the same region of central Veracruz reports only a slight decrease in all coffee plantations from 1973 to 1990 and from 1990 to 2003 (Martínez et al 2009).…”

“…In a high altitude coffee-growing region of centraleastern Veracruz, recognized for its high quality specialty coffee, one LULCC study showed a slight increase in areas of mixed agroforestry systems with shade-grown coffee from 1990 to 2003 (Muñoz-Villers and López-Blanco 2008). In contrast, coffee plantations cultivated without shade were converted to other uses such as sugar cane and pasture (Muñoz-Villers and López-Blanco 2008).…”

Land use/land cover change dynamics and drivers in a low-grade marginal coffee growing region of Veracruz, Mexico

et al. 2010

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.

This article provides an overview of some of the recent research in ecological informatics involving remote sensing and GIS. Attention focuses on a selected range of issues including topics such as the nature of remote sensing data sets, issues of accuracy and uncertainty, data visualization and sharing activities as well as developments in aspects of ecological modeling research. It is shown that considerable advances have been made over recent years and foundations for future research established. BackgroundGeotechnology has been couched as one of the three "mega-technologies" of the 21 st century, along with nanotechnology and biotechnology (Gewin, 2004). On the cusp of the second decade of the 21 st century it is evident that recent developments in the geotechnologies of Geographic Information Science (GIS) and remote sensing have had a substantial impact on ecological research, providing spatial data and associated information to enable the further understanding of ecological systems (Rundell et al., 2009). In a digital society there is sometimes an expectation that information is just a click away and this may apply to spatial information in the domain of ecological informatics. Indeed, it has been in the last five years that developments in and relating to the fields of GIS and remote sensing, such as those seen in internet technologies (e.g., Web 2.0; high performance communication networks; Brunt et al., 2007), sensing technology (e.g., quantum well infrared photodetectors; Krabach, 2000), data standards and interoperability (e.g., OGC® KML 2.2) and spatially explicit modeling (e.g., Osborne et al., 2007), have resulted in the revelation of previously unobservable phenomena and posing of what might be termed second generation of ecological questions. During this time we have also seen more support for the open exchange of data and software and infrastructure for location based services. This paper serves as a review of some of the recent developments in GIS and remote sensing that have been or promises to be of benefit to ecological informatics. The subjects addressed are necessarily selective and limited in scope, drawing on topics of interest to us and, we hope, to you.

Historical landscape photographs for calibration of Landsat land use/cover in the northern Ethiopian highlands

The combined effects of erosive rains, steep slopes and human land use have caused severe land degradation in the Ethiopian highlands for several thousand years, but since the 1970s however, land rehabilitation programs have been established to reverse deterioration. In order to characterize and quantify the transformations in the north Ethiopian highlands, a study was carried out over 8884 km² of the Tigray highlands of northern Ethiopia. Using Landsat Multi Spectral Scanner and later Thematic Mapper imagery (1972, 1984/86 and 2000), historical terrestrial photographs and fieldwork (2008), we prepared land use and cover maps. (1) a gradual but significant decline in bare ground (32% in 1972 to 8% in 2000), (2) a significant increase of bushland (25% to 43%) and total forest area (including eucalypt plantations, 2.6% to 6.3%) and (3) creation of numerous lakes and ponds.
