Continual access to precise information about the land use/land cover (LULC) changes of the Earth’s surface is extremely important for any sustainable development program in which LULC serves as one of the major input criteria. In this study, a supervised classification was applied to three Landsat images collected in 1986, 1998and 2018, providing mangrove forests change data in the coastal are...
in this paper we emphasize the importance of questioning the global validity of significant concepts underpinning global health policy. this implies questioning the concept of global health as such and accepting that there is no global definition of the global. further, we draw attention to ‘quality’ and ‘empowerment’ as examples of world-forming concepts. these concepts are exemplary for the g...
Due to the large volume and mass of materials used, construction industry is one sectors with highest environmental impact. However, provide good quality, affordable, low-energy housing, business case must be maintained. Accordingly, we aimed develop test a calculator measure ecological footprint embodied carbon in used projects standardized way, without need for or even civil engineering exper...
Abstract Landslide susceptibility is a measure to express the high or low probability of an area experiencing landslide disaster which has impact on community very necessary for mapping Tirtomoyo Watershed including Tirtomoyo. From 2014 2022, experienced 147 landslides caused material losses and casualties. The aspect assessment in watershed basic reduce risk loss. This study aims map landslide...
There are anecdotal reports that upstream water withdrawals over the past 50 years have altered the salinity structure of coastal Georgia estuaries. Since few consistent salinity records exist, it may be possible to use shifts in vegetation to document salinity change. The purpose of this study was to use aerial photographs and GIS analysis to determine if the location of the brackish water int...
Indonesia has a huge potential of mangrove resources. In 2010, the mangrove area was 5,209,543.16 hectares and the area was decline rapidly to 2,496,185 hectares in 2016. This figure shows depletion and degradation of mangrove ecosystem and therefore, the capacities to supply human needs are decline because of the intense pressure from many activities in the development of coastal zone. The dat...
Of the 110 000 to 180 000 hectares per year on which prescribed burning has recently been conducted in Canada, 70 000 to 150 000 hectares per year (mostly in British Columbia) has been burned for vegetation management purposes. Such purposes include silviculture, control of plant parasites, promotion of desirable plant species, and conservation of natural ecosystems. The emphasis of prescribed ...
G engineering can improve crop quality and agronomic performance. Biotech crops produced by this technology can potentially benefit producers as well as consumers in both developed and developing countries. The creation of the first genetically engineered (GE) organisms in the 1970s initiated a still ongoing debate regarding their safety. Despite this concern, GE crops have been increasingly ad...
We consider a spatial problem arising in forest harvesting. For environmental reasons, blocks harvested should not exceed a certain total area, typically 40 hectares. Traditionally, this problem, called the adjacency problem has been solved by forming a priori blocks from basic cells of 5 to 20 hectares and solving the resulting mixed integer program. Better solutions can be obtained by includi...
