4 <strong>Conservation</strong> <strong>agriculture</strong> historyInstitutionsSee appendix 1 for a complete list of conservation <strong>agriculture</strong> institutes andprojects.Selian Agricultural Research InstituteThe Selian Agricultural Research Institute (SARI) is the biggest agriculturalresearch institute pioneering conservation <strong>agriculture</strong>. Its objective is to attainsustainable household and community food security. It focuses on crops, soils andlivestock. SARI has several on-farm trials in Arumeru District, including integratedsoil fertility management, zero-grazing and agroforestry. It conducts station trials,which many farmers visit during field days. Some of the demonstration plots includesubsoiling, cover crops, intercropping pigeon pea, and crop rotation. The institute isalso a resource centre for agricultural information.SARI has been involved with conservation <strong>agriculture</strong> since 1999, developing notilling,intercropping, and soil cover. Similarly, SARI has been able to distribute covercrop seeds to the district council, farmers and conservation <strong>agriculture</strong> projects and isaccelerating the use of cover crops. SARI collaborates strongly with other organizations.SARI has given lablab seeds to 586 farmers in Arumeru (see appendix 3.)Heifer Project InternationalHeifer Project International has a long history in Arumeru District. It mainlypromotes improved dairy cattle under zero-grazing. The project emphasizesestablishing pasture before a farmer can receive a heifer and support from HeiferProject International. Pastures are established in plots and along contour bundsfor fodder and stabilizing the bunds. Heifer Project has a strong influence on soiland water conservation, since a farmer has to establish fodder grown on contourbunds.Soil <strong>Conservation</strong> and Agroforestry Programme in ArushaThe Soil <strong>Conservation</strong> and Agroforestry Programme in Arusha (SCAPA) is acommunity land-management programme, operating since 1989. In 1989, itobserved that in various agroecological zones, crops and fodder had stunted growth,low productivity and sensitivity to even short dry spells. The roots of pigeon pea,shrubs and fodder crops revealed serious restriction from hardpan 10–12 cm belowthe surface (Mwalley and Mawenya 2002). The hardpan was caused by mechanizedhoeing and ploughing.SCAPA entered into partnership with RELMA and started introducing, testingand designing conservation tillage with farmers in 1998. Contour constructionwas undertaken by the new partnership. Later, it was apparent poor infiltration ofrainwater into the soil led to high runoff between the fanya chini terraces (Mwalleyand Mawenya 2002). Reduced tillage techniques, rippers and subsoilers, were18 Maguzu et al.
introduced with complementary soil conservation measures and agroforestry. Theaim was to have long-term improvement in crop yields and land productivity.The programme has on-farm trial plots to test and develop, with farmers,conservation tillage under varying rainfall, soils, slope and use of farm machinery.In Arumeru District, farmers from three villages, Likamba, Ngorbob and Sakila,provide land for trials.Research, Community and Organizational Development AssociatesIn 2003, Research, Community and Organizational Development Associates(RECODA), with Help to Self-Help in <strong>Tanzania</strong> and Danida, introduced diversifiedcrops, reduced tilling, and cover crops in Likamba, Manyire, Nduruma and Ngorbobvillages, with support from the <strong>Tanzania</strong> Assemblies of God. At the same timeconservation <strong>agriculture</strong> was introduced to reduce soil erosion, conserve soil moistureand restore soil organic matter (RECODA 2005). The organization introduced foddercrops and is planting them along the contours— lablab, mucuna and improved pigeonpea—and breaking compacted soil with rippers. Banana leaf mulch, made fromleaves and the pseudostem, are used for livestock feed, balancing the needs of bothlivestock and the soil. Three villages, with 300 farmers, benefited from lablab, pigeonpea and mucuna seed and rippers provided by the project. The organization workswith other institutions and the government to enhance conservation <strong>agriculture</strong>.Participatory Agricultural Development and Empowerment ProjectThe Participatory Agricultural Development and Empowerment Project (PADEP) isfunded by the World Bank in collaboration with the <strong>Tanzania</strong>n government. Its focusis to ensure that farmers realize their problems and needs, use technology throughparticipatory approaches, and design crop and livestock projects that will improvetheir livelihoods. In Arumeru District, the project targeted 30 villages by the end of2005; 14 villages had already designed their projects. The farmers are organized infour groups in each village, each group with 40 family representatives.<strong>Conservation</strong> Agriculture for Sustainable Agriculture and Rural Developmentin Southern and Eastern Africa<strong>Conservation</strong> Agriculture and Sustainable Agriculture and Rural Development(CASARD) is a regional project in East Africa, with technical support by FAO, tofacilitate and accelerate profitable conservation <strong>agriculture</strong> by small-scale farmersin Arumeru, Bukoba and Karatu Districts in <strong>Tanzania</strong>. It mainly uses farmer fieldschools, which emphasize farmer-created techniques. In Arumeru, six conservation<strong>agriculture</strong> facilitators helped 11 groups, 325 farmers (148 males and 177 females).Each group has a long-term lease on a trial plot.The groups received basic training in conservation <strong>agriculture</strong>. Five farmers weretrained to operate and maintain conservation <strong>agriculture</strong> implements. The groupsmeet weekly to work on agroecological analysis, an integral part of the farmer fieldschool. Group leadership guides the groups through daily activities, discussions anddecisions. The farmer group receives supplies and equipment from the project:Arumeru District 19
