Causes
The excessive consumption and degradation of vegetated land from livestock.
What is overgrazing?
The degradation of this biome is a result of desertification.
What is grassland/ semi-arid region?
Talking to these group of people will help understand effects of desertification.
What are local people?
Anthropogenic activity has done this to rates of desertification.
What is increased?
Improper irrigation, over cultivation, and fertilizer misuse are components of this cause.
What is unsustainable agriculture/farming?
Cattle overgrazing and their dispersal of these type of seeds leads to desertification.
What are shrubs?
This type of agriculture can inhibit the spreading of drylands and help farmers use the land more effectively.
What is sustainable agriculture?
These develop under shrubs when there is an accumulation of nutrients.
What are islands of fertility?
The process of clearing lands of natural vegetation which leads to soil degradation.
What is deforestation?
Off-road vehicles increase the rate of what in relation to soil.
What is erosion?
These types of activities can prevent erosion and weathering which destroy the land.
What are planting trees and collecting moisture in the soil?
The effect of desertification on albedo.
What is increases?
This cause creates higher demands of natural resources and expansion of urbanization.
What is overpopulation?
This is reduced as a consequence of less variety plant life.
What is biodiversity?
This element is essential to maintaining fertility in soil and thus, needs to be “fixed” into the ground.
What is nitrogen?
This continent is largely affected by desertification.
What is Africa?
This cause creates global warmer temperatures, decreases in precipitation, and drought like conditions.
What is climate change?
Desertification reduces this in the soil.
What is fertility?
Instead of allowing a uniform distribution of water and other soil resources, this phenomenon allows shrub invasion.
What is heterogeneity?
This framework helps with the identification and creation of factors necessary for research, management and policy making regarding desertification.
What is the Drylands Development Paradigm?
