Maziwa Zaidi (More Milk) in Tanzania―Best-bet technologies and innovations: Manure management improves soil structure and food security and mitigates greenhouse gas emissions

  1. 1. Maziwa Zaidi (More Milk) in Tanzania: Best-bet Technologies and Innovations 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. This document has a Creative Commons Attribution 4.0 International Licence. October 2019 March 2017 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 Maziwa Zaidi thanks all donors and organizations which globally support the work of ILRI and its partners through their contributions to the CGIAR system Resource requirements (low to high, between 1 and 5) Land Water Labour Cash Access to inputs Knowledge and skills Impact areas (low to high, between 1 and 5) Food security Nutrition and food safety Youth empowerment Women empowerment Livelihoods Market access and linkages Outcome difficulty Low High Business profitability Environmental sustainability Youth empowerment Women empowerment
