Land Degradation

The implications for future government planning for land degradation include the Soil erosion policy and notices and the contaminated land policy.

“Erosion occurs when the soil lacks protective vegetative cover”. (Pimentel, Kounang, 1998) “Soil erosion reduces the productivity of the land by loss of water, soil, organic matter, nutrients, biota, and depth of soil.” (Pimentel, Kounang, 1998) With no conservation methods in place in certain places like: no contour farming, no cover crop, no terraces, no water ways, and tillage on steep hills is asking for a loss of productivity from the land. The effects on the land that non-conservation methods have is horrible. “Its effects are pervasive, and its damages are long lasting. (Pimentel and others 1995a)” (Pimentel, Kounang, 1998) Soil loss is a bigger factor then most people think. For an example an comparison of how much soil is actually lost in certain environments: “On sloping agricultural land under tropical rainfall, as much as 400t/ha/yr of soil is lost (Pimentel unpublished report,1990).”(Pimentel, Kounang, 1998) “Under arid conditions with relatively strong winds, as much as 5600t/ha/yr of soil has been reported lost (Gupta and Raina 1996).” (Pimentel, Kounang, 1998) Soil loss is a huge factor when conservation practices are not put into place. “According to some investigators, approximately 75 billion tons a fertile soil are lost annually from the world’s agricultural systems (Myers 1993).” (Pimentel, Kounang, 1998) Soil loss is a huge factor and many different things can be done to help slow it,

People have seriously affected the land. We utilize it to develop harvests to sustain our developing populace. We additionally utilize it to give vitality. Every year one individual in North America utilizes assets equivalent to more than 12 sections

Neglect to take care of the land after many decades is starting to show significant negative effects on the environment. Many people do not know what all entails land pollution other than the commonly known pollutions such as chemical and waste, the list may surprise you. The list includes sewage treatment, nuclear waste, construction, urbanization, industrialization, landfills, mining, logging, agricultural practices. and deforestation (Rinkesh). As humans, we have continued to develop as a species technologically, communally and agriculturally. The effects we have had on the environment through human development has not been

I care deeply about the planet Earth, the home humans originate from, so it pains me to watch “modern” society devastate natural life across the board. I feel personally connected to the issue of how we use our land. Having lived in the Lee County area since birth, I have noticed just in our own little part of the world how much “development” can change things. There used to be so much more plant life: trees, grasses, flowers and a myriad of other greenery. What was once considered “empty” lots, by some, have been adapted to suit human desires be it additional roads, restaurants, shopping malls, and a continuing spread of “chain” corporate industries. Beyond human structures, huge amounts of land also are cultivated for industrial farming

The aim is to identify and associate landforms, rock types and soils to the natural environment and its plants and animals and also to investigate the history of the local environment, comprising human impacts over the last 50 years. The impact of human alterations to the environment includes increased soil erosion and changes in river flows.

This causes the desertification and it also slows down progress for finding areas that can be medicine for certain diseases. Grasslands act as a big sponge, as they are able to absorb the rain that falls throughout the grassland. Because of this, there's fertile land, and abundance of nutrients for migrating wildlife. In south Africa, companies have put non-native trees in the grassland which is taking away nutrients from the area. In the Florida Everglades, they're only about 80 Florida Panthers left. The big problem that I notice is that we are able to make plenty of land for agriculture but not for people. In only three years, farmers in Zambia have created food security for 16,000 farmers. Glaciers are melting all run the world, however the speed of this has went up three times as much in the last 50

Erosion is a global problem, as we have already seen (umich.edu). Globally, topsoil is eroding faster than it can be replaced over 1/3 of the world's croplands (umich.edu). In the U.S, the loss of topsoil has been estimated to cost $125B per year (umich.edu). As you might imagine, this is a very difficult calculation to perform, since topsoil production rates are so slow, the lost topsoil is essentially irreplaceable (american.edu). This has been increasing within the past for years and corporations are trying to lessen the amount of erosion but it does not seem to be working

For centuries the world has depended upon the land as their number one resource. The threat of not being able to cultivate that land could trigger a chain of catastrophic events that would reach far beyond

As lack of water and a particularly dry climate out competes shrubs, trees, and grasslands across Colorado, erosion rates increase reducing the infiltration of moisture into the soil. Causation is believed to have come from heavy livestock grazing, fire suppression, and the introduction of exotic annual plants. Habitat problems for animals and communities that rely on ranching and hunting have been directly affected by these desertification effects. Desertification has had large ecological impacts on the state of Colorado. Vegetation and ecosystems are among the most crucially impacted by the effects of desertification. While Colorado continues its dry drought like climate, restoration of soil becomes one of the major solutions to fight off desertification. Because of the overuse of our land in past generations, we are continuing to see the harmful effects due to desertification. The overall impact on humans produced by desertification is best noticed by a diminishing food production as well as a wealth of water sources becoming dry. People in affected areas are likely to experience poor water quality, dust storms, and pollution. More importantly, as soil loses its nutrients, it no longer becomes farmable; thus, impacting local businesses, livestock, and the many people in that community. If desertification continues in Colorado, an increase of lost farmlands and livestock will pose an economic decease within agriculture markets, farmers will be forced to move to find better

In more recent times, the interactions of people and the landscape have influenced the landscape and the life that depends on it. Swampland has been drained, cleared and cultivated, roads have been constructed, and homesteads established. Wildfires were stopped and non-native vegetation was introduced. Pollutants have also degraded water quality. Non-native

Ranch Land Restoration In order to asses the condition of land I would begin by estimating the population of domestic herds and examining levels of grazing by looking for evidence of invasive plant species encroaching to an unhealthy extent (Prior, 2014). I would also assess the condition of native grasses, streams, ponds and lakes in order to get to get a better idea of the land’s current potential (Prior, 2014). Healthy soil is essential to sustainable agriculture. 2 In order to examine the land’s soil I would estimate the percentage of the ground that is bare so that I could determine the potential for soil erosion (Prior, 2014). After noticing shrubs encroaching on grassland areas, significant soil erosion and the overgrowth of invasive

Environmental Science Professor Delia Comeau Case Study: Grassland Soil Erosion Overgrazing of grasslands is an issue occurring in many areas around the nation. In fact, it is the leading cause of all soil degradation, being responsible for more than 30 percent (Withgott & Lapostata, 2014, p. 222). Overgrazing has many consequences: land degradation; poor soil quality; invasive species of weeds and plants; 1loss in biodiversity; increased flooding prevalence and increased magnitude; even a possible contribution to climate change (Withgott & Lapostata, 2014, p. 229; Hogan, 2010). When faced with 500,000 acres of public land that are enduring these issues, many steps need to be taken in order to determine the future of the land and if grazing will be allowed to continue. One of the main ways of helping determine the future use of the land is in the soil quality. By observing the soil color, pH, texture, and structure, the proper means of restoration and conservation can be better determined.

It takes up to three hundred years for one inch of agricultural topsoil to form so soil that is lost is essentially irreplaceable. The consequences for long-term crop yields have not been sufficiently measured. The amount of erosion varies from one field to another. This depends on the type of soil, the slope of the field, the drainage patterns and the crop management practices. The effects of the erosion vary also. The areas that are better able to sustain erosion without loss of productivity are areas with deep organic loams. This is more sustainable than the areas where topsoil’s are shallower.

Desertification is a term few people recognize and even fewer are concerned about. This paper will cover what desertification is along with why it is a global crisis, what the root causes of desertification are, what can be done to reverse the harm full desertification process, it will also cover how farmers can work together to prevent future desertification.
