Transcript of Assessment Task 1 - Year 8 Geography

Land Degradation Land degradation occurs when land becomes unstable due to human activity and therefore causes the land to become unusable for purposes such as agriculture. What is Land Degradation? The Nature of the Issue Land degradation can be seen from a number of different perspectives. These include from farmers, scientists and governments. For example, heavy rain might be seen by scientists as a sign of flooding or erosion but farmers would see this as a benefit for farming. What are the Different Perspectives? Different Perspectives
relevant to the Issue What must Governments do to fix Land Degradation? The Responsibility of
Governments to the Issue What are Governments doing to fix Land Degradation? What are Individuals doing to fix Land Degradation? The Action of Individuals,
Groups and Governments What causes Land Degradation? Land degradation is caused by a variety of reasons, including deforestation, overgrazing of livestock and flooding. Land degradation can be classified into four categories:
The productivity of the land where it produces minimal or no vegetation, or a loss in biomass (biological material from living organisms)
The land is no longer useful because all of its resources have been depleted
The loss of biodiversity, for example, a decline in the environmental quality such as the loss of a range of species
The ecological risk where the land is unsafe and prone to disaster Governments must work together in order to prevent land degradation as it does not simply apply to one country, but to many countries around the world.

Individuals do not fulfill as much an important role as groups or governments but they can support the prevention of land degradation through donations to non-government groups and treating land that they own properly. Non-government groups, such as the UN, play a major role in coordinating governments to fix land degradation. To do this, they hold conferences and meetings for governments to discuss world events. They also provide funding the reduce the impact of land degradation and raise awareness of the issue. Governments work together in order to fix problems such as land degradation and by working together, they create treaties and new laws concerning land degradation which will encourage other people to prevent the spread of land degradation. Many international treaties were constructed at the 1992 UN Conference in Rio de Janeiro, Brazil. Documents that relate to the use and degradation of land include the following:
The Rio Declaration on Environment and Development and Agenda 21 which are plans of action. They instruct all levels of governments and other major non-government organizations on how to promote ecological sustainability and eradicate global poverty; and
The Statement of Principles for the Sustainable Management of Forests which outlines how the sustainable use of forests and arable land can meet the economic, social, ecological and cultural needs of all communities within each country. The Statement also stresses the importance of government action in the sustainable development of land. The Convention to Combat Desertification was developed at the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro. The previous Plan of Action to Combat Desertification (PACD) developed in 1977 had not made any significant impacts. The new approach, the UNCCD, focuses on promoting sustainable land development in small rural communities. From this Convention, other committees and documents have been produced to help the effectiveness of the Convention. National Action Programs help provide a framework for combating desertification based on community needs. The diagram below shows the major reasons of land degradation across the different continents. Land degradation takes a huge toll on humanity because it reduces food production and agricultural outcome. However, humans also require resources such as wood and minerals, which result in widespread deforestation and mining respectively. These practices severely damage the earth and place humans in a difficult position. Governments must therefore educate people such as farmers, especially in poor rural areas, about proper farming practices to reduce the impact of bad irrigation methods and overgrazing of livestock. Government funding is required to repair current areas affected by land degradation that are still able to be repaired. Planting trees may reduce erosion which leads to land degradation. Despite this, land degradation is seen by all groups to have a negative effect on the environment because it degrades the quality of the soil and causes the soil to be deprived of nutrients. Governments are also responsible for their own land and to check that it does not become degraded. The video below shows what different people think about land degradation in Cambodia.
