Land use conflict in Kajiado District, Kenya

This study explores land use conflict in S.E. Kajiado District, Kenya. The conflict reflects ongoing competition over access to scarce land and water resources between herding, farming and wildlife, that has been conspicuous for over 30 years and is intensifying. While the complexity of the dynamic interactions and land use conflicts can be described, and significant driving forces identified, future outcomes are uncertain. The existing land use pattern represents the contemporary imprint of these interactions and it sets the basis for the future. Understanding the conditions that have created the present should, therefore, assist in devising future development strategies.     

The forest transition: Towards a more comprehensive theoretical framework

Building on the contributions of Mather and others, this paper offers an approach for developing a more comprehensive theory of the forest transition. We argue that long-run changes in forest cover in a country or region cannot be separated from the overall pattern of land use changes. Moreover, this pattern is determined by relative land values; forest cover changes over time as the value of one land use relative to the value of its competing use changes over time. However, the actual values that are used to allocate land may be far from optimal; that is, the presence of market, policy and institutional failures can distort economic and political incentives that can lead to bias in favour of one type of land use over the other, and may ultimately explain why a forest transition may be delayed unnecessarily in some countries and regions.     

Intra-regional variation in land use and livelihood change during a forest transition in Costa Rica's dry North West

The work reported here examined intra-regional differences in land use and livelihood changes made by landholders during a forest transition in a dry region of North-West Costa Rica. It drew on the Sustainable Livelihoods Analysis framework to evaluate a qualitative, comparative study of landholders’ access to livelihood resources in two key landholder groups across five communities. Research findings show that while forest outcomes were similar across the two landholder groups and the five communities (net forest recovery), the livelihood dynamics leading to these outcomes varied. One important factor influencing this was small differences in the geographic location of the five communities, which shaped the effect of mediating institutions and policies on the accessibility and deployment of livelihood resources. The findings point to the importance of locally tailored interventions that reach beyond the field of forest conservation and management. These would include interventions to strengthen rural peoples’ access to resources needed to adapt livelihoods to changing socio-economic conditions. They would also include programs to reduce locally felt trade-offs between conservation and development. The findings also raise doubts that Costa Rica's payments for environmental services (PES) program, as it is currently structured, is an effective mechanisms for linking forest recovery and sustainable rural livelihoods in this particular region.     

Land degradation in the Lao PDR: Discourses and policy

While there is an important body of research on environmental discourses and policy in Southeast Asia, the situation in the Lao PDR remains understudied. This paper builds on debates related to environmental change and knowledge production and examines the socio-political construction of the current mainstream discourse on land degradation in Laos. It highlights that, despite significant uncertainties as regard the extent and severity of the issue, land degradation in the uplands is represented by the Laotian authorities and many of their development partners as a major and imminent threat to the development of the country. The paper also examines the way this perspective is translated into policies specifically aimed at resolving the upland issue and proposes an alternative reading of this process where mainstream discourse and associated policy appear partly shaped by the subjectivities and political economic projects of Laos’ policy-makers. Finally, drawing on the case of Laos, the paper provides a critical reflection on conventional approaches to assessing socio-environmental issues and defining policy interventions.     

Forest transitions: An introduction

When people speak about ‘forest transitions’, they generalize about the ways in which the extent of forested land changes as societies undergo industrialization and urbanization. Alexander Mather coined the term ‘forest transition’, outlined a theory to explain it, and carried out a series of careful historical studies to illustrate the idea. The papers assembled in this special issue both extend and deepen Mather's pathbreaking work. They suggest that the idea of the forest transition, like the much critiqued idea of a demographic transition in population studies, has become a useful theoretical tool for understanding contemporary land use changes.     

Stakeholder perceptions and governance challenges in urban protected area management: The case of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area,Philippines

The conservation and management of protected areas in urban settings has become increasingly challenging with dynamics over land use change in adjacent urban areas being highly relevant to, but at times conflicting with, the protected area. This study seeks to better understand the implications of land use change processes to urban protected area management through the case study of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) in Metro Manila, Philippines. Factors and processes influencing land use change and protected area management and the impact of stakeholders’ perceptions on protected area were analyzed. The urban protected area in itself has limited influence on its surrounding urban areas, as land use change in these areas is shaped more by social, economic and policy/institutional factors occurring within the context of urban-regional development. The study also found that land use conflict is evident in an urban protected area due to the competing ecosystem services derived by various stakeholders. This discord is deepened by the lack of coordination between land use planning and protected area management. Integrating protected area management with land use planning through legally binding instruments, specific timeframes and clear internal procedures can help resolve land use conflict for an urban protected area at the strategic or policy level.     

Land use transitions: Socio-ecological feedback versus socio-economic change

The concept of land use transition highlights that land use change is non-linear and is associated with other societal and biophysical system changes. A transition in land use is not a fixed pattern, nor is it deterministic. Land use transitions can be caused by negative socio-ecological feedbacks that arise from a depletion of key resources or from socio-economic change and innovation that take place rather independently from the ecological system. Here, we explore whether the sources of land use transitions are mostly endogenous socio-ecological forces or exogenous socio-economic factors. We first review a few generic pathways of forest transition as identified in national case studies, and evaluate the varying ecological quality of expanding forests associated with these pathways. We then discuss possible explanatory frameworks of land use transitions. We use the case of the recent forest transition in Vietnam as an illustration. Socio-ecological feedbacks seem to better explain a slowing down of deforestation and stabilization of forest cover, while exogenous socio-economic factors better account for reforestation. We conclude by discussing the prospects of accelerating land use transitions in tropical forest countries.     

Is Oregon's land use planning program conserving forest and farm land? A review of the evidence

Planners have long been interested in understanding ways in which land use planning approaches play out on the ground and planning scholars have approached the task of evaluating such effects using a variety of methods. Oregon, in particular, has been the focus of numerous studies owing to its early-adopted and widely recognized statewide approach to farm and forest land protection and recent experiment with relaxation of that approach in 2004 with the passage of ballot Measure 37. In this paper we review research-based evidence regarding the forest and farm land conservation effects of Oregon land use planning. We document the evolution of methods used in evaluating state land use planning program performance, including trend analysis, indicator analysis, empirical models, and analysis of indirect effects on the economic viability of forestry and farming. We also draw on data documenting Measure 37 claims to consider the degree to which Measure 37 might have altered land use and development trends had its impacts not been tempered by a subsequent ballot measure – Measure 49. Finally, we provide a synthesis of the current state of knowledge and suggest opportunities for future research. Common to nearly all of the studies we reviewed was an acknowledgement of the difficulty in establishing causal relationships between land use planning and land use change given the many exogenous and endogenous factors involved. Despite these difficulties, we conclude that sufficient evidence does exist to suggest that Oregon's land use planning program is contributing a measurable degree of protection to forest and farm land in the state.
