There are many crops that have originated from drylands. These crops include olives, rye, barley, saffron and cotton along with their wild relatives. As a matter of fact, one third of the plants that are cultivated have originated from drylands. These crops are important for humans because they are used in daily food such as bread, soups, etc. Cotton is also used for a number of purposes such as clothing, medicinal purposes, household items, etc. Its seeds are crushed to make oil.
Deforestation is not sustainable in the long run as it is the main reason for extinction of many species due to which the ecosystem gets disturbed. Secondly, forests help to maintain the climate of the Earth. When trees are cut down, carbon dioxide in the atmosphere is not absorbed which causes global warming as it traps the heat in the lower level of atmosphere.
Grazing can be used for land restoration naturally. For this reason, farmers are using planned grazing as it can be used for the growth stimulation of plants. Reforestation is also used for this purpose as growing more trees automatically improves the issues regarding soil such as soil erosion. Reducing soil erosion improves land restoration.
Forming institutions for monitoring and assessment of issues regarding land restoration is easier to overcome because if the government is willing, it can easily develop such institutions that can conduct monitoring at all levels. Therefore, political unwillingness is the most difficult to overcome because changing the mindset of the government is not possible when it only considers monetary factors.
