1. LP Assignment 1: Spatial Multi-Criteria Analysis Borders Carrasco National Park Denny Dalvan Majokko Tropical Forestry
2. Content  The following slides contain flow charts for the GIS steps and GIS maps at the end.  Flow charts:  Waterways Maps:  Main roads -Mask  Slope -size of area  Reclassify -my area  Extract by mask -basemap with characteristic (zoom in)  Clip -climate (rainfall and temperature) -population -vegetation and a trip through time regarding vegetation
3. Description of site and problem The study area lies at the norder border of Carrasco national park Bolivia. This area is inhabited. The main activities of the locals are agriculture and timber. The thing that makes this a problem is that the activities are shifting into the the national park. As example you can see that the main roads don’t stop at the border (purple line in the image) of the national park.

13.  In my are there are 2 villages, Israel and villa Zabala. I’ve selected all towns and cities from the places shapefile. After that I calculated the distances to these towns and cities using allocation. I than selected the relevant colums and the result is my_places_pointDistanc e1 on this slide and the next one.
14. This is how it was back in 1970. It can be observed that even then there were activities in the area. That can be seen by different types of green in the area, patterns and rectangular shapes. All of the above means different types of vegetation
15.  Not the best satellite photo. Nonetheless changes can be observed. The patterns around the river have become smaller. Almost seems like there is less activity in the area and recovery of vegetation. But in the north (the white polygon) there are activities. The vegetation there is less dense and open.
16.  There are new developments to be seen. A road (the red line) can clearly be seen going from north to the south west. The yellow polygons show signs of activities. The vegetation is less dense in these areas than in the south. It seems open in these areas or very short bushes.
17.  If there were any doubts, this image proves it. Fragmentations can be seen and other shapes with short bushes. The activity in the area is more. It seems there are grasslands. Different roads can be seen. The dark green color (dense, high forest) is getting less and is moving south. The vegetation on the river sides is also dense
18.  Quiet interesting is to see that the changes are not only in the white circle. The rivers are expending in and out of the area. There are multiple roads in and out the area. More open patches, more colors can be seen. Dense forest, open land and short bushes. The activities are moving to the south. The dense dark green in the circle is left alone. Probably because of the elevation.
19. Zoom in 2021 Types of vegetation • High dense forest • Forest edges • Grass lands • Open/no vegetation • Recovering vegetation/ short bushes
20. Population  More activities means more people in the area. As you may have noticed in the previous slides, everything is moving to the south. There is were the border of Carrasco national park is. This means that the pressure is getting higher and higher on the park.  The next slide give an overview of population (in rasters) of the area. There, one may observe that the less populated areas (darkest rasters) are the highest (probably very steep) and the river area. The elevation map in the slide 21 shows that the south is indeed the highest.

22. Climate in ‘my area’. I’ve used annual mean temperature and annual precipitation. As it is shown the temperature throughout the year doesn’t differ much. It’s colder in the south, the higher places,.
23. This slide show the rainfall in the area.
24. Elevation  lowest and highest value of elevation of the area
