Natural resource management and forages
Alan Robertson
Consultant
Workshop on forage and fodder tree selection for future challenges —Linking
genebanks to forage use, Addis Ababa, 16-20 March 2015
Approaches must encompass:
• Stabilisation of degraded slopes etc (mostly
communal)
• Improved sustainability of existing mixed
farming systems
Gradual shift towards more intensive
management
Lessons from heavily populated parts of Asia
Higher land pressure = higher adoption rates
Protection of crop land
Integrating high quality forages into farming
systems
For smallholders, need to emphasise
species/strategies with potential for spontaneous
adoption
Reinforcement of stock exclosures
Wynn Cassia
Paspalum nicorae
Infertile acid soils
High seed production
Shrubby stylo
American jointvetch
Desmanthus spp
“Oversowing” communal land
(broadcasting legumes e.g. 0.1 – 1.0 kg/ha)
Environmental diversity
= Need for wide array of genetic material
Supply of planting material
Seed or vegetative?
Seed – emphasis on perennial or self-
regenerating legumes
Vegetative multiplication
All grasses for smallholders Many legumes
Many small, very widely scattered sites
300-500 fold increase per year ??
Contract or nursery production feasible (for distribution to new areas)
Emphasise farmer-farmer exchange
Do we have existing programs?
• Major government thrust, major donor interest
• Massively funded existing programs
• Chance for major impact with targeted
interventions to reinforce existing programs
(genetic material, establishment technology, and
delivery mechanisms)
• Linkages ??
Gaps
• Local availability of suitable genetic material for
degraded sites
• Planting material for areas with emerging salinity
• Forages with superior nutritive value for mixed farming
systems
• Sufficient planting material for quick start-up
• We do not need prior “research”.
Quick start
• Multitude of sites with wide array of useful
genetic material to facilitate:
– Spontaneous natural spread
– Spontaneous farmer-farmer adoption
– Localised monitoring and refinement of
recommendations
– Local training/ extension option
– Opportunistic multiplication….seed or vegetative
Need very large volumes, low-cost seed
e.g. 200 t/annum of perennial legumes for Ethiopian programs
alone
• Wide range of species
• Clusters of smallholders, and
• Opportunistic harvesting
• Crucial to set an appropriate contract price.
Timing, scale, beneficiaries, partners
• Need immediate familiarisation with existing
interventions
• Immediate injection of genetic material into existing
programs…
• Will need free seed program for communal areas
• Scale: dependent only on supply of planting material
• Feeds/seeds program not currently geared for this
Sustainability
• Depends on local community support
(promising)
• Depends on conspicuous early benefits
– Erosion control
– Improved hydrology (downslope smallholder
irrigation)
– Improved livelihoods (improved access to quality
cut/carry feed, improved livestock productivity)
– Improved fuel-wood supplies
– Labour impacts (5-2)
