Africa Population- 13% of the world’s population Population growth rates- 2.2- 2.8 % Increase population- deforestation, reduced land sizes, conflicts, poverty, food insecurity etc.. Result- expanding Arid and semi-arid areas in Africa Poor soil fertility, is the major food-production constraint across much of the West African Sahel Introduction Changing farming systems due to deforestation
3
Highly seasonal, unpredictable rainfall, water scarcity and a hot climate. Unsustainable land management Degradation of critical resources such as water, vegetation cover and soil fertility Dry lands Malnourished plants -Poor root systems Few small-scale farmers in these drought-prone regions dont use fertilizer due to cost limitations and the perceived risks of crop failure Impacts Dryland village in dry season, Sudan.

4
Adapting germplasm to adverse soil conditions Enhancing soil biological activity Optimizing nutrient cycling to minimize external inputs Improve farmer's access to fertilisers Solutions
5
Farming Techniques Microdosing Zai ‘Warrantage’ system Grains kept in a warrantage store. Picture courtesy of ICRISAT Sorghum; Picture courtesy of ICRISAT
6
The application of small quantities of inorganic fertilizer in the planting/seed hole Practiced by many small scale farmers in Africa Benefits Increase crop yields Reduce cost of production Crop mature rapidly Escape the worst effects of drought Microdosing Microdosing top dressing Hill preparation for planting
7
18,000 tons of grain $7 million less in food relief 170,000 households benefited in 2004/5 45% yield increase 25,000 small-scale farmers in West Africa are thriving, using micro-dosing fertilizer technique (ICRISAT communication) Microdosing impacts
8
Integrated use of hill placed soluble fertilizer, phosphate rock (PR) and crop residue gave the highest millet yields Microdosing impacts
9
FAO leading technology sharing thru >300 NGOs >10,000 farmers now using P in the Sahel Yields up by 1-3 times even in drought years Could have saved $ 80 million in food aid in 2005 Niger drought Scaling out in Southern Africa
10
A traditional technique for conserving water and rehabilitating degraded land Practiced mainly in Mali, Burkina Faso and Niger Also known as tassa in Niger A system with a series of man made pits, or holes, dug on abandoned, or unused land Basins prepared during dry season Zaï technique Rainwater basins, and resulting healthy crop stand on left
11
Holes is to capture runoff Zaïpits are dug approximately 80 cm apart to a depth of 5 to 15 cm and with a diameter of 15 to 50 cm Does not require a lot of inputs and money - Affordable to resource poor farmers Success of zaï technology Zaï technique
12
The Sahelian Ecofarm technology in Sadoré Use of Stone walls and zaï technology to reduce run-off loss and further degradation. These technologies are used in conjunction with a warrantage system that ICRISAT Research Station (Sadoré ) near Niamey, Niger Sahelian Ecofarm
13
Restoration activities are being carried out on a large scale. A tractor and ripper are used to break the soil crust Local villages sow seed of herbaceous species and the plant trees. *plants will serve as fodder DMP site at Kouré, Niger
14
The incomes of farmers using fertilizer “micro-dosing”and inventory credit system or “Warrantage”have been observed to increase by 52 to 134% The ‘warrantage’ system and its success Microdosing resulted in surplus production Farmers suffered low produce prices at harvest Prices rose up to 3 times 10 months later Warrantage encourages farmers to store their produce a little longer to benefit from the improved prices If you want me to smile.. Feed me first
15
Conclusion Dry lands can be productive Simple, precise agriculture methods can save life There is need to compact deforestation Promoting technologies among small scale farmers alone is not enough, credit facilities help them implement these technologies Collaborative efforts to fight hunger in dry lands needs to be embraced
