Overgrazing in the context of "Desertification"

The Panachaiko (Greek: Παναχαϊκό, "Panachaean"), also known as Vodias (Βοδιάς) mainly at the Middle Ages, is a mountain range in Achaea, Peloponnese, Greece. It spans about 20 km in length from north to south, and 15–20 km from east to west. It is the northernmost mountain range in the Peloponnese. The highest point, named Pyrgos Palavou (Πύργος Παλαβού), is 1,926 metres (6,319 ft).

The mountain is home to two shelters, Greece's largest wind farm with 40 generators, which opened in 2006, and two communications stations. Snow is common in areas over 1,000 m in the winter. Paragliding is common in areas under 1,100 m. Due to overgrazing, frequent forest fires, and the appropriation of land for housing, the mountain's ecology and soil have suffered greatly, to the extent that much of the soil is now barren or can only support herbaceous vegetation. The range is sparsely forested, mainly on its western and southern slopes, while the most fertile areas lie on the eastern and western slopes.

The Egypt–Israel barrier or Egypt–Israel border fence (Hebrew: שְׁעוֹן הַחוֹל, romanized: Sheʽon HaḤol, lit. 'sand clock') refers to a separation barrier built by Israel along its border with Egypt. Initial construction on the barrier began on 22 November 2010, and its original purpose as a common fence was to curb the large influx of illegal migrants from African countries into Israel. However, in the wake of the Egyptian Crisis after the 2011 Revolution, Israel's southwestern border with Egypt experienced an increase in militant jihadist activity with the outbreak of the Sinai insurgency. In response, Israel upgraded the steel barrier—called Project Hourglass by the Israel Defense Forces (IDF)—to include cameras, radars, and motion detectors. In January 2013, construction on the barrier's main section was completed; the final section was completed in December 2013.

A number of countries, including the United States and India, have sent delegations to Israel to observe its border-controlling capabilities and the various technologies used by the IDF to secure Israel's boundaries against the Arab states. Some of these countries have expressed an interest in implementing Israeli strategies and technologies with their own border fences; the Trump administration cited Israel's border strategies as inspiration for the barrier built by the United States along its border with Mexico, while Indian officials have discussed the implementation of an "Israel-type model" for the barrier built by India along its border with Pakistan.

Land degradation is a process where land becomes less healthy and productive due to a combination of human activities or natural conditions. The causes for land degradation are numerous and complex. Human activities are often the main cause, such as unsustainable land management practices. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and wildfires.

One of the impacts of land degradation is that it can diminish the natural capacity of the land to store and filter water leading to water scarcity. Human-induced land degradation and water scarcity are increasing the levels of risk for agricultural production and ecosystem services.

Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution (from a single discharge point) to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, i.e. killing local wildlife or contaminating drinking water, and downstream effects such as dead zones caused by agricultural runoff is concentrated in large water bodies.

Management practices, or ignorance of them, play a crucial role in the amount and impact of these pollutants. Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts. Bad management practices include poorly managed animal feeding operations, overgrazing, plowing, fertilizer, and improper, excessive, or badly timed use of pesticides.

Nomadic pastoralism, also known as nomadic herding, is a form of pastoralism in which livestock are herded in order to seek for fresh pastures on which to graze. True nomads follow an irregular pattern of movement, in contrast with transhumance, where seasonal pastures are fixed. However, this distinction is often not observed and the term 'nomad' used for both—and in historical cases the regularity of movements is often unknown in any case. The herded livestock include cattle, water buffalo, yaks, llamas, sheep, goats, reindeer, horses, donkeys or camels, or mixtures of species. Nomadic pastoralism is commonly practiced in regions with little arable land, typically in the developing world, especially in the steppe lands north of the agricultural zone of Eurasia. Pastoralists often trade with sedentary agrarians, exchanging meat for grains; however, they have been known to raid.

Of the estimated 30–40 million nomadic pastoralists worldwide, most are found in central Asia and the Sahel region of North and West Africa, such as Fulani, Tuaregs, and Toubou, with some also in the Middle East, such as traditionally Bedouins, and in other parts of Africa, such as Nigeria and Somalia. Increasing numbers of stock may lead to overgrazing of the area and desertification if lands are not allowed to fully recover between one grazing period and the next. Increased enclosure and fencing of land has reduced the amount of land for this practice.

Wakhan National Park is a national park in northeastern Afghanistan. Established in 2014, the park encompasses the entire Wakhan District of Badakhshan Province, extending along the Wakhan Corridor between the Pamir Mountains and the Hindu Kush, bordering the Gorno-Badakhshan autonomous region of Tajikistan to the north, Khyber Pakhtunkhwa and Gilgit-Baltistan in Pakistan to the south, and the Xinjiang autonomous region of China to the east.

Flora and fauna in the Wakhan National Park include some 600 plant species, the snow leopard, lynx, wolf, brown bear, stone marten, red fox, Pallas's cat, ibex, Marco Polo sheep, and urial. Remote and largely above the tree line, poaching and overgrazing, rather than mining and logging, currently pose the main threats. Around 15,000 Afghans of ethnic Wakhi and Kyrgyz background reside in the area. Foreigners must have an Afghan visa to tour the area.

Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. Ravines, gullies, buttes, hoodoos and other such geologic forms are common in badlands.

Badlands are found on every continent except Antarctica, being most common where there are unconsolidated sediments. They are often difficult to navigate by foot, and are unsuitable for agriculture. Most are a result of natural processes, but destruction of vegetation by overgrazing or pollution can produce anthropogenic badlands.
