2. INTRODUCTION
 Old Art but new Science
 Diversified farming system
 Efficient land use
system

3. Systems of Agro-forestry
Agri-silviculture Silvi-pastureAgri-silvipasture
Taungya system
Silvo-Fishery system
Shifting Cultivation

4. Advantages of Agro-forestry System
 Reduction of pressure in Forest
Conservation of biodiversity
 Reduction of soil erosion
 proper recycling of nutrient
 Improvement of microclimate
 Increment in factors of income
reduce loss due to crop failure
 Beneficial products like firewood
grasses,fodder,timber, medicinal plants
 Good supply of adequate nutrients
 carbon sequestration & mitigation of the
climate change

6. Limitations
• Competition between trees & crops for light, space &
nutrients
• Trees are the major hosts of insects, pests that harms the
crops
• Requires more input , budget , manpower & time
• Requires technical knowledge to establish agroforestry

7. Tree Crop Interaction
 Beneficial to shade loving plants
 Nutrient recycling
 Wind breaks
 Shelter for pests
 Trees & crop roots bind soil
 Control pollination

8. Agro-forestry increasing Crop Productivity
 Prevention & control of soil erosion & landslide
 Nutrient cycling:
- Release and recycling of nutrients
- carbon through carbon sequestration.
- Nitrogen fixation trees
- Leaf litter Increase OM
- Geen manuring
Microbial activity:
- Mycorrhiza & phosphate solubilizing bacteria
- Rhizobium bacteria
 Land Utilization:
- Wasteland & degraded land utilization
- Afforestation technique

9. Crop Protection:
- Crop protection from frost and weather change
- Wind break
- decreases the incidence of pest and diseases
Establishment of micro-climate:
-provides shade for shade loving plants
- maintains temperature and light penetration
- increases precipitation by 10%
- and decreases temperature by 3-8%
Maintaining soil nutrients:
- Lesser Evaporation & efficient nutrient utilization
- Tree roots absorbs heavy materials like Arsenic
- Green manuring
-Mulching

12. Research and Development Activities
 Nepal Agroforestry Foundation (NAF) :
 Collaboration with Action Aid Nepal, Poverty Alleviation Nepal, National
Agricultural Research Development Fund, Nepal etc.
 Running projects like”right based Approach on food security and gender equity”,
“Domestication high value MAPs( Medicinal & Aromatic plants) for promotion
of Agroforestry system & sustainable economic development of Nepal”.
 IUCN(International Union for Conservation of Nature):
It is the world’s oldest & largest global environmental organization that is
continuing 5 year project since 1st April 2013 to 31st March 2018 at Kabhre
palanchok & Lamjung district funded by ACIAR(Australian Centre for International
Agriculture . The title of project is “ Enhanching livelihoods & food security from
Agroforestry & Community forest in Nepal”.

13.  ICRAF ECA(World Aroforestry Centre’s East & Central
Asia regional Office):
• “Distribution of Lapsi in the Himalayas” &“Spatial
Modelling of climate change impacts on two major cash crops(
Banana & Coffee) in Nepal”
.
