6. Reduce poverty with livestock: SDG01
• 1 billion people rely on livestock for their livelihoods
• Livestock give poor households reliable cash income
• Livestock demand is highest in developing countries
- Over 50% increase in demand for milk, meat, eggs
in the next three decades in developing countries
7. Empower women with livestock: SDG02
• Women undertake up to 70% of agricultural work
in many parts of the world
• Almost two-thirds of the world’s 1 billion
poor livestock keepers are rural women
• In the Gambia:
52% of sheep owners,
67% of goat owners, are women
• In Chiapas, Mexico:
sheep husbandry is women’s business
• In Afghanistan:
traditional poultry raising is carried out entirely by women
8. Ensure healthy lives with livestock: SDG04
• Animal-source foods (meat, milk, eggs)
present food safety risks
• 60% of human infectious diseases and 75%
of other emerging diseases (e.g., bird flu),
are ‘zoonotic’ (come from animals)
• ‘Top 13′ zoonoses each year kill 2.2 million
people and make 2.4 billion people ill
• We need better disease surveillance, animal
husbandry and marketing; risk-rather than
rule-based health controls; pro-poor policies.
9. Ensure food/nutrition security with livestock: SDG05
• Milk, meat, eggs provide essential
protein, energy, micronutrients
• Consumption of even small
amounts of animal-source foods:
- combats under-nutrition
- improves cognitive development
- increases physical growth
• Developing countries lead
in global food production
- 500 million smallholders support
more than 2 billion people
- smallholder crop-livestock systems
produce about 50% of global food
Conway 2012; Herrero et al. in press
10. Enable sustainable livelihoods with livestock: SDG06
• Livestock make cropping possible,
and sustain it over the longer term
• Smallholder producers are competitive:
More than 85% of Kenyan milk is
produced by 1 million smallholders
• Livestock provide means for women to
earn incomes, for households to save and
build assets, for farmers to plough their land
11. Manage natural resources with livestock: SDG07
• Livestock are a main user of land and source of GHGs
• Importance of manure: 23% of nitrogen for
crop production comes from manure
• Crop residues contribute up to 70% of the diets
of ruminant animals in developing countries
• Grass still makes up 50% of all the biomass
consumed by the world’s livestock
• We can improve livestock efficiencies
in poor countries without moving
to industrial grain-fed systems

19. Possible GHG opportunities
• Develop capacity for quantifying
GHG emissions from agricultural sources
• Develop ILRI into a ‘competence centre‘
for GHG measurements in Africa
• Build network of GHG labs across Africa and
elsewhere to allow developing countries
to obtain country-specific information
about their agricultural GHG emissions
• Identify pro-poor mitigation options for
smallholder agriculture in the developing world
20. Developing countries can mitigate GHG emissions
without moving to industrial grain-fed systems:
e.g., through improved efficiencies
(e.g., better feeds and feeding systems)

25. Pay livestock keepers for wildlife conservation
Payments for wildlife conservation can provide pastoral communities
with income to pay for livestock vaccines, food and school fees
26. Pay livestock keepers for environmental services
Payments for environmental services may help developing countries
‘green’ their livestock sectors through better climate regulation,
watershed management and biodiversity conservation
28. Manure problems/management
Manure problems
• Livestock disconnected from land in intensive systems
• Concentrated livestock produces local nutrient overloads
• Handling manure is difficult
• Anaerobic digestion can have trade-offs
Manure management
• Technical solutions are available but need to be tailored
• Better integration of livestock-crop farming
• Improved composting
• Recovering nutrients and other valuables
• Biogas production (fermentation)
• Manure refinery (bio-enzymes)
29. Opportunities for manure management
• Manage manure and
nutrient cycling to maximize
the use of nutrients and
capture of methane
• Make and support policy
and institutional changes
that promote responsible
waste management
• Improve breeds to reduce
GHG emissions from manure

Livestock systems in developing countries now produce about50% of the world’s beef,as well as 41% of our milk,72% of our lamb,59% of our porkand 53% of our poultry(Herrero et al., 2009);In south Asia more than 80% of farms are less than 2 hectares; in sub-Saharan Africa smallholders contribute more than 80% of livestock production; and globally farms with a few ruminants, such as two cattle and half-a-dozen sheep or goats (i.e. 2 tropical livestock units (TLU)) and 2 hectares of land contribute 50-75% of the total livestock production. South Asia and sub-Saharan Africa have 45% and 25%, respectively, of the world’s 725 million poor livestock keepers (FAO 2012b).
Notes from Tim:Livestock production and products have huge value for the world's poor.That small-scale livestock production can be encouraged to be carried out in the most environmentally sustainable way.Whilst the smaller producers of the developing world are likely to be net victims (rather than contributors)of global climate change and other forms of degradation of the environment –and so need rather urgently to adapt to this –they do also contribute to climate and environmental harmand so we must encourage practices that minimize that contribution. The contribution of livestock producers from different types of production system – be they 'smallholders', semi-intensive or industrial producers –need ultimately to be quantified both in absolute and relative (i.e. intensity) terms.Whilst the absolute share from smallholders (for example of GHG emissions) may be less than that from larger producers –the emissions intensities are almost certainly much higher – and that is being addressed in ILRI research.
This new map of greenhouse gas efficiency per kilogram of animal protein produced,made by Mario Herrero, an agricultural systems analyst formerly of ILRI and now at CSIRO,shows that the current large inefficiencies in livestock production in developing countriesoffers great opportunities to make smallholder livestock systemsboth more productive and environmentally friendly.
Notes from Tim:The three 'areas' of the Global Agenda of Action – which were determined by a wide group of stakeholders at the inception meeting in Phuket in 2011 – do seem to cover the range of issues rather well.
Note from Tim:Improving natural resource use efficiency is all about closing yield gaps and there is great potential for this in the often very innefficient smallholder systems. But yield gaps need here to be taken in context of people's needs and objectives within different systems. It is not simply a matter of closing yield gaps it is a matter of optimizing productivity to a number of ends, and understanding why some of these ends (pastoral production systems, for instance) might not easily lead towards the closure of yield gaps. Where are the opportunities is the question we need to be asking.
The methane produced by livestock can be halved by doing very simple things,such as:improving the quality of the crop residue feedprocessing the feedgiving a slightly more balanced diet to livestock.

Note from Tim:2) Restoring value to rangelands is an important consideration in some of the systems with with we deal. It is here that there are possibilities in relation to payment for environmental services, for example.

ILRI and partners are leading a project in Burkina Faso and Ethiopia to investigate the potential of payments for wildlife conservation on rangelands in these two countries..Past ILRI research in Kenya shows that such payments have helped pastoral households:To purchase life-saving vaccines and treatments for their livestock, the basis of their livelihoodsTo buy nourishing foodsTo pay school fees
In the developing world there is increasing interest in payment for environmental services (PES) as an instrument for environmental management that can also generate impact on poverty reduction particularly in rural areas.To date, there are few examples of PES targeting livestock keepers. A recent ILRI report, Greening livestock: Assessing the potential of payment for environmental services in livestock inclusive agricultural production systems in developing countries, assesses the potential of payments for environmental services (PES) in various livestock inclusive farming systems in the developing world.Application of PES to livestock inclusive agricultural production systems describes examples of emerging and operational PES in livestock inclusive agricultural production systems. This includes PES for climate regulation, watershed management and hydrological services, and biodiversity conservation.Among key findings:• Although livestock are widely distributed across agro-ecosystems of the developing world, there are still very few PES schemes that specifically involve livestock keepers. Besides, there are opportunities for livestock keepers to benefit from PES for climate regulation, watershed and biodiversity conservation.• Increased demand and scarcity of some environmental services generated from livestock production create opportunities for implementing PES schemes in livestock inclusive agricultural production systems but currently methods and tools for measurement and verification of environmental services are not well developed.• Although there is considerable potential for private markets in PES, experience shows that public funding remains essential for public and quasi-public goods such as biodiversity conservation, particularly at national and global scales.PES schemes offer a diversification potential to livestock farmers for improving their livelihoods and for poverty alleviation. The cash flow generated through PES schemes produces multiple benefits including: poverty reduction, store of wealth, income diversification and multiple social and cultural gains.• PES is a tool to consider for promoting agricultural transitions towards a green economy. PES schemes have the potential to stimulate a green livestock sector, allowing farmers to adopt sustainable agricultural land management (SALM) practices that reduce the impact on the environment and help conserve biodiversity and ensure sustainable use of natural resources. This could provide a triple win: provision of environmental services, biodiversity conservation and livelihood improvements.
Note from Tim:3) Reducing waste is becoming increasingly important in areas where the high densities of smallholders, operating inefficiently but at the same time disconnected from the land-base, are contributing to these awful inefficiencies in nutrient-cycling. There are massive possibilities for improving this through manure management and such-like. Again, it is a matter of looking for the opportunities.
