availability of <strong>agriculture</strong> credit, availability and effectiveness of agriculturalextension service, farmers’ awareness of the available technologies, farmers’ abilityto afford and apply the technologies and overall agricultural infrastructure all areissues that must be considered in promoting conservation <strong>agriculture</strong> in terms of aninnovation system. The challenges that farmers are facing in adopting conservation<strong>agriculture</strong> technologies and practices, not just obstacles to adopting and diffusingit, should be met first in one way or another. In addition, farmers believe stronglyin what they have being doing; they are hesitant to change to new things unlessthey see that immediate benefits are attached to the new practices. <strong>Conservation</strong><strong>agriculture</strong> programmes covering different farming systems are needed rather thanuncoordinated short-term projects.Adoption and diffusion rely heavily on the district agricultural and planningoffices, as they have the mandate to plan and coordinate all agricultural activitiesin their area. They need to create awareness in their communities and identifyinterventions needed in various localized areas; that is, promoters of conservation<strong>agriculture</strong> should avoid blanket recommendations. An environment of conducivepolices and their enforcement, incentives, inputs and subsidies, credit and loans,and marketing can all serve as a good driving force to ensure adoption and upscalingof conservation <strong>agriculture</strong>.All the problems mentioned here call for comprehensive measures that will tackleseveral issues together. Given that Karatu District is one of the most agriculturallyproductive and one of the most popular tourist destinations in <strong>Tanzania</strong>,environmental conservation should be given a higher priority. Environmentalconservation integrated with agricultural development activities will lead intosustainable land husbandry practices. New appropriate agricultural and naturalresource management technologies and practices together with indigenousknowledge for environmental conservation and <strong>agriculture</strong> improvements will breakthe vicious cycle of poverty and environment in many communities and create anavenue for sustainable rural sector development in different localities, such as indifferent farming systems, or agroecological zones.13 Recommendations• Currently many projects and institutions that have been working in agriculturaldevelopment, including in promoting conservation <strong>agriculture</strong>, have notattained full participation of stakeholders. Therefore, stakeholders in Karatushould be identified and coordinated towards a common focus in achievingthe set objectives of introducing conservation <strong>agriculture</strong> technologies andgaining their adoption, diffusion and scaling up. Collaboration should bemade possible with government bodies (agricultural research, district counciland village government), like-minded international and local organizations,small-scale farmer beneficiaries, local artisans and suppliers of inputs andimplements. Preferably the district agricultural office should be empowered tocoordinate all conservation <strong>agriculture</strong> activities in their area, with informationand experience-sharing forums. This should be mandatory, not optional.94 Ringo et al.
• Districts should have proper documentation (a database) of all conservation<strong>agriculture</strong> and related natural resource management activities. Thedatabase should be well documented, that is, who is doing what, where andfor what purpose.• Project sustainability, achieved through encouraging beneficiaries’ projectownership, and capacity building in conservation <strong>agriculture</strong> should becarefully observed so as to ensure that the project will continue even afterdonor support is phased out. Holistic approaches and interdisciplinaryimplementation of activities should be put into place to ensure that farmersare developed in a wide spectrum, both socially and economically.• Because problems are localized, no single solution can cut across the manygeographical and socio-economic conditions in Karatu District. Facilitatorsshould have this in mind and whenever possible use indigenous technologies.Experience, self-motivation and creativity in conservation <strong>agriculture</strong>practices and community mobilization skills are required of all extensionistsdealing with conservation <strong>agriculture</strong> promotion.• Community sensitization and awareness creation in conservation <strong>agriculture</strong>might lead farmers to be ready to participate fully in conservation <strong>agriculture</strong>technologies and practices in their areas. Beneficiaries should be provoked toexpress concerns about their lives and any options that they think may lead topoverty reduction, food security and environmental conservation. In SWOT(strength, weakness, opportunities and threats) analysis of conservation<strong>agriculture</strong> technologies in the area in question, communities should decide ifsuch interventions would help them. They should be encouraged to establishroot causes of key agricultural production constraints. Participatory communityaction plans (CAPs) should be drafted, outlining what is to be done, by whom,and when, and the materials required. Monitoring and evaluation should beundertaken, while a mechanism of feedback will allow all stakeholders to knowwhat is going on. Up-scaling procedures for the introduced innovations shouldbe in place to ensure diffusion of the innovations to the entire community.• There should be a trusted and reliable contact person or group in the villageto facilitate mobilization and implementation of conservation <strong>agriculture</strong>activities in the absence of NGOs or institutions that are introducing theinnovation. This would help to coordinate the community, facilitate projectactivities, and bridge communication within the community, between localcommunities and the implementing agency, and from the agency back to thecommunities.• Cost-benefit analysis should be conducted on all farm enterprises to ensureoptimum decisionmaking with regard to what to produce, and when and howto produce it. It is important to apply conservation <strong>agriculture</strong> in the widercontexts, whereby different crop types (wheat–barley, maize, banana, onions)can be considered. This will enable farmers to opt for crops that have goodreturns in terms of yield, low cost of production and a good price at market.Keeping livestock in conservation <strong>agriculture</strong> technologies should be takenas an opportunity and not a threat; therefore the conservation <strong>agriculture</strong>Karatu District 95
