Dynamic The watershed of Lake Atitlán in the Highlands of Guatemala is displayed for instance of the abnormal state of intricacy found in a framework that includes regular, social, and financial powers cooperating in a little however to a great degree assorted topographical range. This publication portrays our endeavors to utilize a multidisciplinary way to deal with study the two principle powers of regular and social change in the range: espresso creation and tourism; and in addition to see how these connect with an exceptionally entwined arrangement of organizations. We utilized Landsat TM pictures to contemplate the huge changes in area use achieved by the expansion in espresso generation in the most recent decades. This yield has implied blended favors regarding vegetation spread for the region. Our investigation demonstrates that espresso has been the absolute most essential reason for timberland spread misfortune in the range: 14% of the area was changed from woods to espresso somewhere around 1986 and 1996. Then again, for the same time frame, shaded espresso ranches substituted 6,000 ha. of corn fields, supplanting a yearly harvest of minimal natural worth with an agroforestry framework that gives living space to untamed life and better soil preservation, among other ecological advantages. Tourism has been another vital power of progress in the territory. Because of its regular excellence and rich social legacy, the Atitlán range has created in the most recent decades as the third most imperative traveler goal in the nation. The quantity of lodgings, resorts, and chalets around the lake has expanded by a component of five in the most recent forty years. Once more, the blast in this industry has been a blended gift for local people: indigenous gatherings who have lived there for many years, and who are presently attempting to adjust to living with untouchables from different parts of the nation and additionally from different parts of the world. These common and social changes are happening with the scenery of an undeniably complex arrangement of establishments interfacing in the zone. We have distinguished seven administrative foundations having locale in the area and different national and global non-legislative associations working principally with the indigenous gatherings who, themselves, fanatically keep their own arrangement of establishments. Regardless of the vast number of organizations present, little is accomplished as far as arranging and dealing with the locale reasonably and the debasement of the ecological conditions is currently apparent in both the area and in the water. We have as of late begun a push to connect an extra arrangement of information to this investigation incorporating land use, social components, and institutional angles. We are analyzing the utilization of biophysical parameters of lake water quality: supplement levels, nearness of fecal microscopic organisms, pesticide deposit levels, and so forth, as integrative pointers of changes in the distinctive elements that influence the assets and the general population in the watershed. The concurrent investigation of sets of information from different experimental controls is a testing errand for the logical group, yet can furnish the leaders with a significant device. Difficulties of Data Integration in the Study of a Complex System: A Case Study of Lake Atitlán in Guatemala Edwin J. Castellanos a , Maricruz de Mejía a,b , Beatriz López b , Nancy Girón, an and Willy Knedel an a Universidad del Valle de Guatemala b Medical Entomology Research and Training Unit/Guatemala-CDC SITE DESCRIPTION Lake Atitlán is a profound lake (340 m) of volcanic starting point situated in the good countries of Guatemala at 1,562 m above ocean level. The lake has no surface outlets; underground gaps and leak openings permit water to channel to two waterways depleting to the Pacific. Lake sides are steep, because of its land causes. The lake lies in a substantial seismic zone. A huge number of Mayan tenants having a place with two etymological gatherings have lived there for a considerable length of time. All the more as of late, the precious stone blue lake has pulled in a huge number of sightseers from around the globe. The lake and its watershed were proclaimed a National Park in 1955. To date, no protection laws are upheld in the territory. The area is viewed as one of the poorest in the nation with high rates of absence of education and general wellbeing issues. Town of Sololá Town of San Lucas GENERAL RESEARCH QUESTION How would we be able to utilize physical and compound water quality parameters as integrative markers of the impacts of human-actuated changes on the assets of a lake watershed? Techniques Landsat TM pictures from 1986 and 1996 were utilized to look at examples of area utilize and land-spread change for the district. Unique accentuation was set on separating espresso manors from characteristic timberlands given the significance of that product on the area use elements for the locale. Band 6 (warm) of the pictures ended up being vital in accomplishing this objective. A complete GIS framework was produced for the region that included physical and social components. Water quality parameters were measured in situ at 28 locales around the lake amid the dry (April) and stormy (September) seasons. Every site was found utilizing a GPS. Tests were taken back to the lab for more modern microbiology and compound examinations. Pertinent financial pointers for the 11 regions that encompass the lake were assembled from different sources.
