Abstract

This paper assessed the potential of integrating marginal land resources and landscape urbanism in biofuel production as a climate change mitigation option in Lagos metropolis. To achieve this view, three level methodological steps were adopted as follows; first, extraction of potential marginal lands from 5 sub-types of land use dataset using Arc GIS mapping system according to a set of criteria, followed by estimation of energy value of the identified marginal lands and lastly, a case scenario analysis of substituting fossil fuel in Bus Rapid Transit (BRT). The outputs revealed a spatial distribution of combined system of linear utilities with setbacks amounting to over 30,850 hectares. At full planation of Jatropha, the marginal lands yielded approximately 37,020 tonnes of Jatropha oil per year, 3072.2 liters of bio-diesel and a gross profit of N12, 131, 898, 240 annually at N128 diesel pump price. The step 3: showed that on 36,892,800km annual mileage, BRT buses in Lagos consumed 22, 873, 536 emit 17,192,044 800g of CO2 while a standing Jatropha seed sequestrate 557, 278.60g CO¬¬2 ha-1 yr-1.In conclusion, the study proposed integration of Jatropha in the design of Lagos metropolitan landscape. Consequently, resultant landscape restoration on the eco-sensitive marginal lands is expected to repair the fragmented city ecological structure and revamp the natural processes as well as enhance biofuel production and subsequently empowers carbon sequestration and resolve the climate change serendipity hoofing around the city’s future.
