Urban cultivation in Accra: an examination of the nature, practices, problems, potentials and urban planning implications

The literature on urban farming in Sub-Saharan African cities reveals that most studies have been conducted in Eastern, Southern and Central African cities. A few have focused on West Africa, including Sierra Leone, Guinea Bissau, and Cameroon. In Ghana there is a paucity of information on urban farming. The purpose of this paper is to examine the status of urban cultivation in Accra, Ghana's capital, reviewing existing research, and to present new empirical findings on urban cultivation emphasizing on its history, nature, practices, problems, potentials and urban planning implications.

阿兰·奈斯论深层生态学的哲学基础

在阿兰·奈斯看来 ,深层生态学既是一种社会思潮 ,又是以这种思潮为指导的一场旨在改变现行实践模式的社会运动。作为一种社会思潮 ,它是一个由一系列基本原理构成的演绎性的逻辑体系。奈斯认为 ,深层生态学的理论内核是八大原理 ,而在其背后 ,还有更为基本的前提与终极规范 ,即各种生态智慧。而奈斯本人的生态智慧的终极规范是 (大 )自我实现

Urban Housing as an Issue of Redistribution through Planning? The Case of Dhaka City

The rapid growth of population, the mushrooming of poor settlements and unplanned urbanization have crucial implications for the efficiency and equity of urban services. The resultant infringements of critical human rights throw into focus the importance of housing as a social policy issue. Urban services are strained in Dhaka city. Urban management has been disrupted as a result of spatial encroachment and environmental degradation. In addition to land scarcity, land speculation and endemic corruption, the high price of land is also a product of the system of land registration. The dearth of valuable urban land, together with delays in urban planning and its implementation, have made the acquisition of land for housing prohibitively expensive for middle and low‐income households. Consequently, the quality of the housing environment is deteriorating. The problem of housing finance is intrinsically linked to its affordability, being currently the prerogative only of the affluent. This article delineates the inherent lack of integrated urban planning, the lacunae within institutions responsible for urban management – and, contextually, the nature of housing as a social policy issue, where reinforced, coordinated planning and administration could ensure distributive benefits even to the poor.
