Improving urban land governance with emphasis on integrating agriculture based livelihoods in spatial land use planning practise in Tanzania

This study examines spatial land use planning and urban agriculture practises in Dar Es Salaam, Tanzania, one of the rapidly urbanising cities in Sub-Saharan Africa. It demonstrates how urban agriculture livelihood can be integrated in spatial land use planning and improve urban land governance by taking Goba, Chango’mbe ‘A’ and Ubungo Darajani as case study settlements. Location and periurban typology are theoretical premises used in this study. These help in understanding the policy and practical premises that constrain urban agriculture livelihood integration in urban land use planning processes and land management principles.

Methodological aspects deployed are documentary search, interviews, mapping, observations, and historical trends analysis. In addition, context, evidence based and institutional links are analytical frameworks used.

The study shows that the urbanisation processes, urban poverty, food insecurity and inadequate community involvement in land use planning are the factors underpinning and catalysing changes in land use, land transactions, immigration and overall urban agriculture proliferation in the city. The implications generated by these factors suggest that poor urban land governance is not only the cause, but it is caused by the weakness of planning institutions to realise and adapt to the new challenges that urban agriculture presents to urban land development process. Correspondingly, the rise of urban agricultural land use by and large, indicates a disparity between the widely cherished planning norms and standards underpinning formal land use planning processes and structures in urban development. These include land use zoning, location, land use change conditions, density distribution, accessibility to resources, land tenure modalities, and equitable provision of basic services in ensuring sustainable use of urban land. Equally, the study indicates the existence of supportive city land development policies and country legislature for urban agriculture, which are in practise faced with health, sanitation and economic return constraints. These constraints increase urban agriculture’s negative perceptions to consumers and decrease acceptance in spatial land use planning processes and output implementation. However, urban agriculture has been observed to make productive use of undeveloped land, green the city, provide income and nutrition, and is often a safety-net function for the poorest sectors of society. As such, it is an important vehicle for poverty alleviation, capital mobilisation, and sustainable use of land.

The study argues that for an unforeseeable future, the growth of the urban agriculture sector is likely to remain an indispensable reality depicting urban land development in rapidly urbanising cities in Sub-Saharan Africa. Inclusion of urban agriculture based livelihoods in spatial land use planning processes and structures, including decision making, preparation, implementation and monitoring are observed rationale for improving the livelihoods of the urban poor-smallholder farmers and space use. This can be achieved through, but not limited to, adopting participatory urban planning approaches, settlement upgrading, institutional collaborations, decentralising roles to the local level and strengthening smallholder organization through institutionalisation and giving them a voice platform in the political dialogue. These options can be effective if the government is able to enforce and review policy and legislatures in place and if different actors are involved in the decision making processes, and if information and communication awareness is established. Other improvement include the use of treated wastewater technology for farming, granting long term tenure security, improving accessibility to resources, and adopting flexible planning standards. The study concludes that urban planners and policy makers have little choice but to ensconce and consolidate emerging forms of urban agriculture based livelihoods within land use planning practises and within a guided planning framework. If urban agriculture forms are not guided, then the negative effects, in the long run can undermine the livelihood of the urban poor and degrade the environment. Thus, there is an urgent need to guide the processes, strengthen institutional structures and linkages in land use planning practises, and consider local communities priorities when working to improve urban land governance in Tanzania.

why most of African towns and cities are mostly squatters and slums Tanzania in particular? what are the challenges for this and what should be done to restructure the situation?

Great piece of work, congrats! I find this a very contemporary topic in Africa. What were your suggestions for further research? I intend to carry out a related study in Kenya as well.
