Department of The University of British Columbia Vancouver, Canada Date DE-6 (2/88) ABSTRACT Urban agriculture is practised in most Third World societies not as a hobby but as a necessity both for subsistence food production and to earn extra income. Africa, and in particular, Tanzania, is no exception. In Tanzania, and especially Dar es Salaam the practice of urban agriculture damages the urban environment. The question addressed by this study was how to explain the persistence of urban agriculture in Dar es Salaam in the light of its evident damaging effects on the urban environment. This study uses data obtained through (a) documentary sources such as government reports and statistics, and (b) field data from interviews and observations. Interviews were held with twenty-nine urban agriculturalists and twenty-seven public officials. On average, urban agriculturalists earned annual net profits from livestock enterprises that were about 15 times the total annual salary income of a low income worker, and six times that of a senior public official. The study also found that respondents with high salary earnings also earned high incomes from their urban agriculture enterprises. Most respondents expressed agreement with most statements about the issues about environmental damage due to keeping livestock. However, less than half the interviewees agreed with those statements related to disease-health issues. Most respondents said that people did urban agriculture mainly for economic motivations. They also agreed that people persisted in doing damaging urban agriculture in part because the City Council did not enforce its bylaws. They also said that the government policy explicitly and implicitly encouraged people to do urban agriculture. Most pubhc officials interviewed agreed that ii most agriculturalists had knowledge about the damaging effects of their practices. This study used factors nested at four contextual levels (government, ministry, city council, and individual) to explain people's persistence in doing urban agriculture in spite of its damaging effects. To lessen environmental damage, this study recommends that: (1) A policy be formulated, (2) The government foster multidisciplinary and coordinated participatory educational approaches that adopt holistic views, (3) The City Council enforces its bylaws aided by other parties, (4) MALCD extension agents offer information inequitably. The study also discusses implications and recommendations for policy, practice, and other areas for further research. iii TABLE OF CONTENTS Chapter Page ABSTRACT ii TABLE OF CONTENTS iv LIST OF TABLES viii LIST OF FIGURES x LIST OF ABBREVIATIONS xi LIST OF APPENDICES xiii ACKNOWLEDGEMENTS xv 1 THE BACKGROUND AND PURPOSE OF THE STUDY 1 Background 1 Purpose and Research Questions 5 Overview of the Dissertation . 6 2 TANZANIA AND THE CITY OF DAR ES SALAAM: HISTORY AND POLITICAL ECONOMY 8 TANZANIA: A BRIEF HISTORY 8 The Region in Precolonial Times 9 The Period of German Rule 11 The Period of British Rule 12 Independent Tanzania: Population and Institutions 14 The Arusha Declaration 16 The Inspiration of Nyerere 17 POLITICAL ECONOMY OF TANZANIA 17 A History of Crisis 18 Decline of Agricultural Production 23 Inflation and the Enterprise of Urban Inequalities 25 THE CITY OF DAR ES SALAAM 32 History and Patterns of Urban Development 32 Economic Patterns in Dar es Salaam 37 The economy: The formal sector 37 The economy: The informal sector 41 SUMMARY 47 iv 3 THE PHENOMENON OF URBAN AGRICULTURE 49 URBAN AGRICULTURE AND ITS BENEFITS 50 Urban Agriculture in its Global Context 51 Urban Agriculture in Africa 56 Urban Agriculture in the City of Dar es Salaam 62 Benefits of Urban Agriculture 67 Urban agriculture for nutrition 68 Urban agriculture for income generation or poverty reduction 69 Urban agriculture for community well-being 70 Urban agriculture for waste management and the environment 70 Urban agriculture for conversion of food items 71 URBAN AGRICULTURE AND ENVIRONMENTAL DEGRADATION 72 The Concept of Environmental Degradation 72 Degradation Due to Animals 74 Risks to health 72 Aesthetic and social concerns 83 Degradation Due to Plants 85 Risks to health 85 Aesthetic and social concerns 87 THE ROLE OF GOVERNMENT IN URBAN AGRICULTURE . 88 National Policies Governing Urban Agriculture 90 The period from 1961 to 1966 90 The period from 1967 to 1970 91 The period from 1971 to 1976 91 The period from 1977 to 1985 93 The period from 1985 to the early 1990s 94 City Policy Affecting Urban Agriculture 96 Means of Ensuring Policy Adherence 97 MALCD extension agents 97 The police and militia 97 The mass media 98 Other agencies for policy adherence 98 SUMMARY 99 4 FIELD RESEARCH PROCEDURES AND THE CHARACTERISTICS OF RESPONDENTS 101 SELECTION OF RESPONDENTS AND DATA COLLECTION . 102 Selection of Respondents -
