Drought and Desertification
What are the possible impacts of a drought?
The impacts of droughts are generally not of risk to humans.
Droughts are temporary phenomena, the potential impacts of which are not serious.
Droughts can result in serious climatic, hydrological, agronomical and geological impacts.
The impacts of droughts are generally only expressed as hydrological and agronomical risks.
What types of drought and desertification exist?
There is only one type of drought and desertification, that related to soil condition.
Drought and desertification cannot be differentiated into types.
The main type of drought and desertification is that of desert environments.
There are several types of drought and desertification, relating to soil, biodiversity, livestock and socio-economic aspects.
Where do drought and desertification occur?
Drought and desertification occur only in semi-arid zones where precipitation is between 350 and 600 mm.
Drought and desertification occur only in sub-humid zones, where precipitation is between 600 et 800 mm.
Drought and desertification occur only in hyper-arid zones where precipitation is less than 100 mm and in arid zones where precipitation is between 100 mm and 350 mm.
Drought and desertification is a world-wide phenomenon with the African continent being that most affected.
What are the potential consequences of drought and desertification?
The consequences of drought and desertification are limited to those affecting humans.
Drought and desertification can have human, socio-economic, environmental and cultural consequences.
The consequences of drought and desertification are limited to those affecting humans and the environment.
The consequences of drought and desertification are limited to those affecting our cultural inheritance.
Can the consequences of drought and desertification be influenced by human behaviour?
The consequences of drought and desertification can only be influenced by protective laws, anti-erosive measures, biomass production, forestation, control and enhancement of water resources, reorganisation of pastoral activities, modernisation of production processes, diversification and development of new activities.
The consequences of drought and desertification can only be influenced by drawing on the “indigenous knowledge” of local communities, educational programmes to raise awareness about desertification and to change attitudes and behaviours, technical training of populations and provision of food aids.
The consequences of drought and desertification can only be influenced by increasing water resources and and improving irrigation techniques that avoid waste of water and soil salinization.
The consequences of drought and desertification can be influenced through a variety of scientific, technical, social and political solutions.
