“…While studies relating to transitions from arable and forest can be readily identified, there is inconsistent use within the literature of the term "marginal" land. The importance of capturing studies that consider marginal land arises from the fact that such land is stated as being crucial for 2G feedstock production [29][30][31]. A number of definitions of marginal land exist (see [32,33]), with the interplay of a range of factors leading to its characterisation as an area that has: (i) previously been used for agriculture then abandoned, perhaps for social or economic reasons, (ii) could not be used for crop production due to specific environmental constraints, or (iii) where land is in a degraded state [30,34].…”

“…As said by Gandy (2013Gandy ( : 1301 ''although the concept of marginal land like waste land has become widely subsumed within various utilitarian discourses concerning the redevelopment of ostensibly empty or unproductive spaces, the idea encompasses a multiplicity of meanings, material origins, and ecological characteristics.'' The concept of marginal land has evolved to meet the multiple management goals and to incorporate the trade-offs of environmental protection, preservation of ecosystem services and long-term sustainability (Kang et al 2013). According to FAO (1993), marginality is actually a complex and dynamic concept that can apply to land utility according to the ability of the people to access it, and hence marginality is a biophysical and social economic term that mirrors the level of technological development at a given place and time.…”

Marginal land use and value characterizations in Lagos: untangling the drivers and implications for sustainability

Lagos, the leading African megacity, is a coastal city located in creeks and riparian environment. In all parts of the city, transactions in marginal lands-riparian or water-logged areas-are increasingly becoming more noticeable. However, while previous studies have focused upon normal land transactions, the dynamics of land uses in marginal regions remain largely unexplained. Information on the dynamics of informal land transactions in the marginal regions of Lagos city is important for urban sustainability. This study therefore interrogates the attributes, uses, values and drivers of marginal land in Lagos using generalized linear model (GLM). Findings show that the predominant land use in marginal areas of Lagos is residential, majority of the lands are less than full plot size, close to river channels and less accessible, and the mean price ranges from NGN 3,156,908 to NGN 4,052,158. The GLM estimations show that distance to river channels/lagoon and buyer's status have more significant influence on marginal land uses and values in Lagos. These findings have significant policy and practical implications for the city's land use and sustainability. For urban and environmental sustainability, there is need to stem transactions in coastal marginal environments of Lagos for their obvious implications for climate change, flooding, erosion, sea incursion, building collapse, natural parks and public spaces, river channels and urban greening.

“…Yet the definition of marginal land has varied across time, space and discipline to meet multiple management goals [25,46]. The concept of marginal land made an appearance in the literature in the 19th century when David Ricardo identified variations in the desirability of land based on its proximity to essential resources, such as water supply or food markets [47].…”

“…However, despite the similarity in stated goals among these works-mapping marginal land for bioenergy production-there remain a number of inconsistencies across studies that make comparisons and standardization difficult, and to date none of the current methods are widely accepted [25].…”

Abstract:As energy policies mandate increases in bioenergy production, new research supports growing bioenergy feedstocks on marginal lands. Subsequently there has been an increase in published work that uses Geographic Information Systems (GIS) to map the availability of marginal land as a proxy for bioenergy crop potential. However, despite the similarity in stated intent among these works a number of inconsistencies remain across studies that make comparisons and standardization difficult. We reviewed a collection of recent literature that mapped bioenergy potential on marginal lands at varying scales, and found that there is no common working definition of marginal land across all of these works. Specifically, we found considerable differences in mapped results that are driven by dissimilarities in definitions, model framework, data inputs, scale and treatment of uncertainty. Most papers reviewed here employed relatively simple GIS overlays of input criteria, distinct thresholds identifying marginal land, and few details describing accuracy and uncertainty. These differences are likely to be major impediments to integration of studies mapping marginal lands for bioenergy production. We suggest that there is future need for spatial modeling of bioenergy, yet further scholarship is needed to compare across countries and scales to understand the global potential for bioenergy crops.
