Answer:
The creation of a "culture of prevention" can go a long way toward protecting drylands when desertification is just beginning and even when it is ongoing. It requires a change in governments’ and peoples’ attitudes. It has been shown that dryland populations, building on long-term experience and active innovation, can stay ahead of desertification by improving agricultural and grazing practices in a sustainable way.
Preventive actions include:
Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation.
Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.
Integrating the use of land for grazing and farming where conditions are favorable, allowing for a more efficient cycling of nutrients within the agricultural systems.
Applying a combination of traditional practices with locally acceptable and locally adapted land use technologies.
Giving local communities the capacity to prevent desertification and to manage dryland resources effectively.
Turning to alternative livelihoods that do not depend on traditional land uses, such as dryland aquaculture, greenhouse agriculture and tourism-related activities, is less demanding on local land and natural resources, and yet provides sustainable income.
Creating economic opportunities in dryland urban centers and in areas outside of drylands.
Answer:
Societal and policy actions need to adjust to the degree of desertification that a society faces or is likely to face. In areas where desertification processes are at the early stages or are relatively minor, it is possible to stop the process and restore key services in the degraded areas. Prevention is a lot more cost-effective than rehabilitation, and this should be taken into account in policy decisions.
Addressing desertification is critical and essential to meeting the Millennium Development Goals which aim to eradicate extreme poverty and ensuring environmental sustainability amongst other objectives.
On average, human populations in drylands have a lower quality of life than people in other areas. Worldwide, approximately half of the people living below the poverty line live in drylands and their societies are particularly vulnerable as a result of dryland ecosystem conditions and poverty. Addressing desertification would therefore contribute to the eradication of extreme poverty and hunger
