The conversion of natural landscapes for human use over the past century has led to significant ecological consequences. By clearing tropical forests, intensifying agriculture and expanding urban centers, human actions have transformed local, regional and global hydrology. Urban landscapes, designed and built atop impervious surfaces, inhibit the natural infiltration of rainfall into the subsurface. Deforestation, driven by the demand for natural resources and food production, alters river flow and regional climate. These land cover changes have manifested into a number of water management challenges, from the city to the watershed scale, and motivated investment into landscape re-greening programs. This movement has prompted the need for monitoring, evaluation and prediction of the hydrological benefits of re-greening. The research presented in this dissertation assesses the contribution of different re-greening strategies to water resources management, from multiple scales. Specifically, re-greening at the city scale is investigated through the study of vegetated rooftops (green roofs) in a dense urban environment. Re-greening at the watershed scale is investigated through the study of forest regeneration on deforested and ecologically degraded land in the tropics. First, the benefits of city re-greening for urban water management are investigated through monitoring and modeling the hydrological behavior of a number of green roofs in New York City (NYC). Influence of green roof size and rainfall characteristics on a green roof’s ability to retain/ detain rainwater are explored and the ability of a soil infiltration model to predict green roof hydrology is assessed. Findings from this work present insight regarding green roof design optimization, which has utility for scientific researchers, architects, and engineers. Next, a cost effective tool is developed that can be used to evaluate green roof hydrologic performance, citywide. This tool, termed the Soil Water Apportioning Method (SWAM), generates green roof runoff and evapotranspiration based on minimally measured parameters. SWAM is validated using measured runoff from three extensive green roofs in NYC. Additional to green roofs, there is potential for SWAM to be used in the hydrologic performance evaluation of other types of green infrastructure, making SWAM a relevant tool for city planners and agencies as well as for researchers from various disciplines of study. Finally, the impact of degraded landscape re-greening is investigated using a case study of 15 watersheds in Puerto Rico that have experienced extensive reforestation. The study provides evidence of improved soil conditions following reforestation, which in effect positively impacts streamflow generation processes. Findings from this work fill a gap in knowledge regarding the hydrological benefits of forest regeneration in mesoscale watersheds and provide guidance for future investment into reforestation programs. Land cover will inevitably continue to change to meet the needs of a growing and increasingly urban population. Yet there is potential to offset some of the ecological effects – especially those on hydrology – that result from land cover change. As a whole, this dissertation aims to contribute knowledge that can be used to make the re-greening of altered landscapes more realizable.

Thesis (M. Dev.) -- University of Limpopo, 2013 / Urbanisation is one among the pressing issues facing human kind today and with it large number of rural poor immigrated to cities, failed by economic growth to get formal employments, large number of the poor are now found in informal settlements around cities where abject poverty, unemployment and extreme hunger is concentrated. Urban Agriculture is viewed as one of the strategies the urban poor employs to cushion themselves from the hardships of poor economic conditions. In contrast, there is a view that urban agriculture exploits labour, generates below poverty incomes and land fetches higher prices in cities, as such providing scarce public resources to this practice is not of economic importance. The purpose of this study was to explore the impact of urban agriculture on poverty, more precisely on the contribution of the practice towards job creation, cash incomes and food security. To determine if, urban agriculture can become a potential avenue for local economic development in the informal settlements of Soweto. Descriptive and quantitative assessments of the variables of urban agriculture in the study area were attempted to validate whether urban agriculture can emerge as a substantial mechanism to eradicate poverty and bring forth a potential area for local economic development in the study area. A questionnaire was used as an instrument for data collection. In the study, some of the facts revealed were that large proportion of the practitioners of urban agriculture are women and few went pass the matric. Moreover, large proportion of the urban farmers were doing so to supplement food at home and surplus sold, on average generating below poverty incomes and no job opportunities were recorded. The study concluded by providing recommendations on how city municipalities, development scientists and policy administrators can ensure that Urban Agriculture is supported in order to offer a potential avenue for local economic development. Some of the recommendations proposed, to cite a few, are that bottlenecks that limit development of Urban Agriculture must be removed, such as policy biasness, especially to livestock production in the cities, provision of infrastructure, tenure system and access to credits to improve productivity of the practice. Provision of advisory service must be conducted in indigenous language to improve adoptability and comprehension to facilitate technological transfer.
