Manure management improves soil structure and food
security and mitigates greenhouse gas emissions
Asaah Ndambi, David Pelster and Klaus Butterbach-Bahl
Key messages and solutions
• Integrated Manure Management (IMM) preserves nutrients for crops,
prevents transmission of certain diseases through manure, reduces
detrimental environmental effects of manure (greenhouse gas emissions
and pollution of water), and offers economic benefits through biogas for
cooking fuel and lighting (replacing firewood and charcoal)
• IMM involves managing manure through animal confinement under roofs
(enables collecting of both feces and urine), covering manure to prevent
nutrient losses, and composting the manure to enable the natural process
of ‘rotting’.
• Biodigestors are a promising IMM practice that:
• Save expenditures and time obtaining fuel sources
• Increase food production from bio slurry as a fertilizer
• Reduce smoke-related diseases
• Preserve forests and reduce environmental degradation
• Provide lighting to help in quality education and household work
Opportunities and benefits
• Adopting IMM will simultaneously help achieve a wide variety of benefits
• Increase crop and livestock productivity
• Inclusive rural development
• Reduce environmental impacts of dairy
• Deliver on national commitments to reduce GHG emissions
intensity
• Agribusiness users best suited to deliver IMM include:
• Agrodealers who can supply farmers with flexi-biogas units
• Extension agents to train farmers on IMM
Suitability
• IMM is suitable for livestock keeping households in all agro-ecological conditions
• IMM is suitable for free range systems, confined systems, deep litter systems
particularly in mixed crop and dairy farming households
Evidence
• IMM practices have been supported by both on-farm
trials and experimental work.
• Application of manure to soil is a long-established way to
improve soil and agricultural productivity. Reducing GHG
emission intensity is a co-benefit.
• This practice is appropriate for anyone with livestock.

Problem statement
• Most farm owners do not realize the value of the manure that is produced
on their farms.
• Moreover, as animal agricultural operations have become increasingly
intensive, many problems have emerged that point to the need for
improvements in manure-management practices.
• When not managed properly, manure can pollute the
environment. This includes ground or surface water pollution
and toxic gases
