The following are some of the primary causes of desertification in our world. Lands turn to desert due to a number of reasons, but much of the desertification that is occurring around the world today is caused by human activity on lands that are extremely vulnerable to overexploitation and improper agricultural methods. However, the main reason why desertification goes widely unnoticed is that 90 percent of people affected by this phenomenon currently live in developing countries, mainly in Africa and Asia, and belong to the world’s poorest. For example, up to 50 percent of the Canadian Prairies spreading over Alberta, Saskatchewan and Manitoba are likely to battle with some of the negative effects of desertification in the upcoming years.Īnd globally, the risk of losing more land is getting higher with increasing summer temperatures and less frequent and erratic rain patterns we are experiencing in the last years. You may be even able to identify the most vulnerable areas yourself, as they include grasslands, steppes, prairies, savannahs, shrublands and woodlands.Ĭountries affected by desertification do not have to be located only in hot regions of the world because it is the local climate and land use that shape the health of the land. Pretty much every continent has some dryland area that is currently threatened by desertification if no immediate preventative measures will be taken. Where is desertification happening the most? The loss of land to desertification has major impact on many places on our planet today and is expected to affect humanity even more in the future as population numbers will grow bigger and the availability of natural resources will decline. The official definition by the United Nations Convention to Combat Desertification (UNCCD) that has been widely used since it’s formulation in 1994 is: “desertification is land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic fluctuations and human activities.” UNCCD also highlights that it is important to note that desertification is not a natural process of deserts expanding to new regions, it is a form of land degradation caused primarily by human activity in vulnerable areas. This is what makes the reversal of the process extremely difficult. Unlike the natural desert ecosystem with well-adapted species still inhabiting the area, desertified lands are often devoid of natural life without a healthy ecosystem in place that would perform life-supporting services, like new soil formation and nutrient cycling. Extinction of species What is the process of desertification?ĭesertification is a process by which fertile land is transformed into desert as it becomes progressively drier and unable to support any plant growth for food production. Sorry if this was already clear, but I prefer to too much clarity to too little.9. This avoid system clutter, problems with conflicting files, etc. After that, you can contribute back to the community by uploading it to the AUR for others to use.Īgain, by building a Pacman package, Pacman can track files and dependencies for the package.
My suggestion was to create a PKGBUILD for ATITD so that you can build (and install) a Pacman package for it with makepkg. Packer, yaourt and other AUR helpers simply retrieve the PKGBUILD files and run makepkg for you (while also retrieving dependencies, which makepkg doesn't).
The AUR is just a collection of PKGBUILD (and related) files. Those functions include the exact commands that you would run on the command line to build the package, which is why creating a PKGBUILD file is so easy. PKGBUILD files are just simple Bash scripts that set metadata (name, description, dependencies) and provide build and package functions. Your reply leads me to believe that there may be some confusion about makepkg/AUR/etc.Īll Pacman packages are created with makepkg from PKGBUILD files.
