Desertification and arid zones – UNESCO’s work over the past 50 years
Thomas SchaafUNESCODivision of Ecological and Earth SciencesProgramme on Man and the Biosphere (MAB)
The beginnings of dryland research:
• 1951: UNESCO launches an international study on arid and semi-arid zones;
First organization within the UN system to address problems in drylands!
• 1965-1974: International Hydrological Decade1975: International Hydrological Programme (IHP)
• 1968: International Biosphere Conference at UNESCO 1971: Man and the Biosphere (MAB) Programme
• Integrated Project on Arid Lands in Kenya (IPAL-Kenya);• Integrated Project on Arid Lands in
southern Tunisia (IPAL-Tunisia);• Integrated Project on Arid Lands in Lesotho (IPAL-Lesotho);• Training and education on integrated pastoral management in the Sahel (FAPIS project);• Strengthening of scientific capacities in
the agro-silvo-pastoral domain (CILSS Member States, West Africa);• Cooperative Integrated Project on Savanna Ecosystems in Ghana (CIPSEG);• Strengthening of scientific capacities in West African biosphere reserves• Sustainable Management of Marginal Drylands (SUMAMAD);
MAB Projects: 1970s - today
1st generation type of project: “Natural sciences research”
Integrated Project on Arid Lands (IPAL) in Kenya (1975 - 1984)KALRES & TREMU follow-up projects (1985-1991)
Kenya
IPAL-Kenya:
Problem: increasing sedentarization of nomads and overgrazing threatening fragile arid ecosystem
Approach: Study of the natural environment to improve living conditions of dryland people
Focus on: carrying capacity of drylands
• health of camels and other livestock (quality over quantity)• growth dynamics of plants as fodder (e.g. Indigofera spinosa)
Elaboration of management guidelines for pastoralists
Ghana
2nd generation type of project: “Natural and social sciences research”
Cooperative Integrated Project on Savanna Ecosystems in Ghana (CIPSEG)
(1993 - 1997)
Problem: degradation of dry sub-humid savanna environment
Causes:• road construction;• spread of settlements;• agricultural expansion;• overgrazing;• bushfires;• deforestation.
Sacred Natural Groves often constitute the last remains of undisturbed natural vegetation and serve as sanctuaries for game and wildlife
The sacred natural groves have survived environmental degradation as they are embedded in traditional belief systems and cultural practices
(3) Training seminars for elders, women, scientists and school children.
(1) Species inventories in sacred groves
Project Activities:
(2) Botanists/zoologists collaborated with anthropologists (traditional knowledge, medicinal plants, taboos related to management/protection of groves
(4) The planting of trees and cash crops in a “buffer zone”around the sacred groves helped to better conserve the natural environment ... and to generate income, especially for women.
