package being introduced should consider crop–livestock integration. Thesecatch words should be considered: locally available resources, intensification,diversification, local interest, and livelihood improvement.• Policy analysis and advocacy of conservation <strong>agriculture</strong> technologiesshould be undertaken to ensure the inclusion of conservation <strong>agriculture</strong>objectives in national agricultural and environmental policies; wheneverpossible, each district should have an agricultural resource centre dealingwith conservation <strong>agriculture</strong> technologies, inputs and implements.Encourage conservation <strong>agriculture</strong> programmes, not projects• Whenever possible conservation <strong>agriculture</strong> packages should give simplehighlights to small-scale farmers about marketing their produce—offeringonly products of high quality, sorting and grading, sending samples todifferent markets, maximizing yields per unit area, advertising, avoidingfarm-gate prices, promoting marketing, working in production groups tomaximize economies of scale, advocating favourable changes in agriculturaldevelopment policy, carrying out cost-benefit analysis to judge which cropto produce, processing, storing and adding value, finding alternative useof the agricultural products, producing in a timely manner to maximizeopportunities afforded when there is scarcity, and producing under contract.• Participatory conservation <strong>agriculture</strong> bylaws should be established to ensurethe enforcement of existing environmental bylaws, which can promote thewide and fast adoption of conservation <strong>agriculture</strong> technologies. Localauthorities should be given more mandate in bylaw enforcement aftercreating awareness to the communities about what ought to be done.• Innovation needs to be upscaled by increasing the number of new conservation<strong>agriculture</strong> practitioners and ensuring full adoption of all conservation<strong>agriculture</strong> practices—no till, permanent cover and crop rotation.• Many farmers have realized the importance of applying conservation<strong>agriculture</strong> technologies in their fields, but the big problem facing themis poverty, which reflects low purchasing power for agricultural inputsand implements. It is important for any project or institution facilitatingconservation <strong>agriculture</strong> technologies to make sure it can link community tocredit agents or establish saving and credit societies.• The community-based approach should be encouraged so that neighbourswho will not abide by the principles of conservation <strong>agriculture</strong> will notjeopardize the achievement of individual households. The area may besubcatchment or subvillage, where land should be set aside for conservation<strong>agriculture</strong> practices, hoping with time they will spread to other areas.• Reports, posters and other informational materials on conservation<strong>agriculture</strong> should be translated into local languages in simple phrases and beavailable in Swahili, to be used by facilitators and farmers. Currently manyconservation <strong>agriculture</strong> reading materials are available only in English.96 Ringo et al.
• With the introduction of conservation <strong>agriculture</strong> in the existing formerpractices of soil and water conservation, it is important to consider thepractices that promote rainfall capture in the soil (on-the-spot rainwaterharvesting) before considering those that aim to control runoff. In all casesthey should be complementary in a sequence, not competing alternatives.• Communities need more awareness of the importance of observing bylawsand regulations to achieve sustainable development. Capacity of goodgovernance at village and ward level is of great importance in ensuring thatbylaws and regulations are enforced.• Farmers should be facilitated to improve their land husbandry, thus providinga more effective response than efforts to combat soil erosion and fertilityimprovement alone.ReferencesBishop-Sambrook C, Kienzle J, Mariki W, Owenya M, Ribeiro F. 2004. <strong>Conservation</strong> <strong>agriculture</strong>as a labour-saving practice for vulnerable households: a study of the suitability of reduced tillage and covercrops for households under labour stress in Babati and Karatu Districts, northern <strong>Tanzania</strong>.
