MarketsThe urban centres are Kikatiti, Kilimanjaro International Airport, Kisongo, Majiya Chai, Ngaramtoni, Oldonyosambu, Tengeru and Usa River. Most of the foodcrops are sold at weekly open markets in urban centres within the district. Coffee,flowers and vegetables from large farms are marketed and sold through privatebuyers or cooperatives. The marketing system is heavily driven by informal networksand establishments. Tanganyika Farmers Association is a public organization.Input traders are agents, retailers and distributors dealing with seeds, fertilizers andchemicals. Market centres also have implement repair services, mainly for repairinganimal-drawn implements.Most often small-scale farmers sell their produce to traders and are expected tobargain for the price for their goods. According to farmers, crops like onion andtomato are sold cheaply because the farmers lack knowledge of how to store themand usually urgently need cash. This gives the trader an upper hand in bargaining.Seeds for cover crops, especially lablab, are mainly available from institutionspractising conservation <strong>agriculture</strong>. After harvesting lablab, farmers get USD 100for a 120-kg bag. Maize fetches TZS 18,000/100 kg at planting time, TZS 10,000–12,000/100 kg during harvest; lablab TZS 100,000/120 kg at planting time, TZS40,000–50,000/120 kg during harvest (TZS 1000 = USD 1).In Arumeru farmers lack an organized way to market their conservation <strong>agriculture</strong>produce. This means middlemen follow them to the farms and dictate low sellingprices. The district is near the Arusha municipal centre, which is rapidly expandingand offers a ready market for most produce. There are also export opportunitiesthrough Kilimanjaro International Airport to Dar es Salaam and Nairobi for onion,banana and flowers (URT 2004). Agricultural stockists are also in the district or inArusha city. Access to supplies by farmers in more remote areas is problematic,since stockists are mainly in urban and semi-urban areas.MechanizationAbout 60–70% of farming in Arusha Region is mechanized. According to the districtagricultural and livestock development office, farmers use tractor-drawn disc andmouldboard ploughs, as well as animal-drawn implements. Between 30% and 40%of the arable land is cultivated with hand hoes. In 2004/05, out of the 51,575 ha ofarable land 25,787 ha was ploughed by tractors, 23,209 ha by draught animals and2,579 with hand hoes. In recent years conservation <strong>agriculture</strong> implements havebeen introduced, especially rippers, animal drawn no-till ploughs and jab planters.InfrastructureGood transport services, such as roads, connect Arusha to Dar es Salaam, Dodomaand Nairobi. However, most roads in the district are not paved and some areas aredifficult to get to. Interior villages are adversely affected by inaccessible roads. Theroads are poorly maintained and damaged during heavy rains but are relativelyaccessible during the dry seasons. Tractors, ox-carts, donkeys, pickup trucks, lorries,14 Maguzu et al.
handcarts and wheelbarrows are commonly used by farmers during harvest. Mostfarmers hire tractors, pickups and lorries, since most cannot afford to buy them.Telecommunications in the area are good. A number of cell phone companies,Tigo, Vodacom, Zantel and Celtel, have networks in most areas. Some farmershave cell phones, making communication easier. There are also Internet servicesand two airlines fly frequently to Dar es Salaam, Nairobi and Mwanza.Economic and cultural characteristicsThe district is diverse in tribes and cultures. In the Maasai and Waarusha tradition,most households own goats and indigenous cattle. Medium-resource householdsown dairy cattle, while low-resource households own goats and sheep. Most villagesgraze animals freely in the village pastures and fields after harvest. During thecropping season high-resource households shift livestock to grazing land away fromthe villages and crops. Medium-resource households rarely shift their animals andmostly keep them indoors or tether them.Hand hoeing is common, especially for small-scale farmers. The communityregards a farmer as serious and competent when he or she uses a hand hoe to weedand keeps the farm clean; if old vegetative material lies on the soil the farmer isregarded as lazy. This is a constraint for changing behaviour to manage organicmatter better. Preparing land is a man’s job, while planting and weeding are mainlythe women and children’s responsibility, though men sometimes assist duringweeding. Communities use traditional irrigation techniques. The district has a widenetwork of community organizations, NGOs and farmer groups.Communities within the Arumeru District are receptive and entrepreneurial in theirdaily lives but have limited capital to finance <strong>agriculture</strong>. High supply prices andlack of agricultural credit facilities are compounded by no competitive financing ororganized farmer groups, which reduce the credit-worthiness of farmers.HealthCommunicable diseases cause most illness and death in <strong>Tanzania</strong>. The leading fivekiller diseases for people five years and older are malaria (22%), clinical AIDS (17%),tuberculosis (9%), pneumonia (6.5%) and anaemia (5.5%). The district’s HIV status hasincreased every year since 1998. Since 1988 the population infected is 3412 (0.65%).Tuberculosis has increased rapidly due to the AIDS epidemic (URT 2003). ArushaRegion has a 14% HIV/AIDS prevalence rate (URT 2002b). Of the eight districts inArusha, Arumeru District has the second highest number of cases, according to thephased-out World Vision <strong>Tanzania</strong> (2002) HIV/AIDS Project evaluation report. InArumeru, there are probably more than 2000 cases and more than 240 orphans. Datain the district depend on voluntary testing. The number of affected people in variousage groups is as follows: 5–14 years old (men 7%, women 13.8%), 15–34 (25% men,52.4% women) and 35–59 (37.5% men, 47.2% women). This shows a wide genderand age bias in HIV and AIDS prevalence (Ringo and Manyelezi 2003). HIV andAIDS affect education and <strong>agriculture</strong>. The able age groups are vulnerable to thedisease, reducing agricultural workforce. The pandemic has mainly hit the youth andArumeru District 15
