This is probably one of the most important questions conservationists have to answer. According to Airame et al. (2003), “marine reserves not only provide a means of establishing sustainable fisheries and long term economic viability, but also contribute to the conservation of habitats and unexploited species, while providing opportunities for marine research and education.” In a nutshell: the aim of such a reserve is to maximize ecological, economic, and cultural benefits and to enhance educational and research opportunities.
The Scimitar-horned Oryx is according to the red list of the IUCN a mammal, which is claimed “extinct in the wild” since 2000. Until the late 1980s at least some animals survived in the wild of Chad and Niger. Originally they lived in habitats across Africa in the semiarid and arid regions of the Sahara desert. This species is nearly extinct due to extensive hunting for its horn and meat. Capturing some of the animals in the mid-1960s secured its survival at least in captivity. Since then some reintroductions to Senegal, Morocco and Tunisia into fenced and protected areas have successfully taken place. Taking into consideration, that it is a migratory browsing species, releasing it to the wild would be necessary to lead it back to natural population.
Reintroducing Scimitar Oryx into its original habitat would not only bring a beautiful highly adapted animal back into wildlife. Furthermore it is an icon for this region and therefore connected with regional pride and emotional importance for local people.
Arusha NP was founded in 1960 as the Ngurdoto Crater NP and in 1967 it was enlarged to the area of Mount Meru. The park is proximate to Arusha town, with a population of 1.694.310, which leads to several land use conflicts and other human impacts the natural environment is exposed to (see City Population, 2012). Current land use belongs to forestry, nature conservation, recreation/tourism and water management. The impacts are wide spread and of high environmental risk due to enclosed agriculture and population growth. An increase in food demand through rising population may lead to an amplification of the spatial pressure. Moreover, the environmental threats are strongly correlated with agriculture because the Mormella Lakes are affected by chemicals of the surrounding farms that are introduced due to high surface run-off (see BirdLife International, 2013).
The EDGE program focuses on the conservation of Evolutionary Distinct & Globally Endangered species. This program uses the approach of raising awareness about the species studying them in the wild and realising long-term conservation. As for the sustainability of the conservation efforts the involvement of local communities is key they play a crucial role in the study implementation phase. The implementation has to provide benefits for the local community and take all stakeholders into consideration. The development of the conservation action plan is based on traditional pathways or ,if necessary, on unusual strategies. In any case local conservation as well as scientific capacities should be built.
A set of R scripts and a guide are being developed as tools for image classification using image segmentation and a random forests classifier. The intent is to provide robust image classification methods that can be used by people with modest remote sensing experience. The guide should be easy to follow. If it’s not please let me know and I’ll try to make improvements by integrating your comments and requests. These methods are still being tested so problems may occur as people apply them to different data sets and for different applications. You can access the scripts and guide on this Bitbucket site: https://bitbucket.org/rsbiodiv/segmentclassification.
Using the rasterVis package in R makes the visualisation of remote sensing time-series data very easy. It requires the raster package as well and can deal with remote sensing derived raster data sets using different plotting commands. However for some plots and specific plotting options further modification might be needed. A very good overview including working examples of rasterVis functions is available at http://rastervis.r-forge.r-project.org/
Creating images to explain certain spatial topics/problems is feasible using either any kind of presentation or diagramming software, however I experienced that it is very hard to create professional looking images, especially if grids, translucency and a kind of 3D view is targeted. Using tikz/pgf requires some more effort in the beginning, but the result compensates for it. Continue reading →
if you are looking for graphics from UN reports and the reports itself, have a look at the UNEP/GRID webpage. If offers a vast amount of reports as pdf and lots of features graphics which are relevant for conservation:
