Historical Changes of Land Tenure and Land Use Rights in a Local Community: A Case Study in Lao PDR

Journal Articles & Books
Dezembro, 2016
Laos

Land-titling programs, land and forest allocation programs, and projects on state-allocated land for development and investment in Laos have been key drivers of change in land tenure. These have triggered major shifts in land use rights, from customary, to temporary, and then to permanent land use rights. This article explores how government programs to grant land use rights to individual households have affected the way people have been able to acquire and secure land tenure.

Landscape and Local Controls of Insect Biodiversity in Conservation Grasslands: Implications for the Conservation of Ecosystem Service Providers in Agricultural Environments

Peer-reviewed publication
Setembro, 2014

The conservation of biodiversity in intensively managed agricultural landscapes depends on the amount and spatial arrangement of cultivated and natural lands. Conservation incentives that create semi-natural grasslands may increase the biodiversity of beneficial insects and their associated ecosystem services, such as pollination and the regulation of insect pests, but the effectiveness of these incentives for insect conservation are poorly known, especially in North America.

Addressing the Externalities from Genetically Modified Pollen Drift on a Heterogeneous Landscape

Peer-reviewed publication
Dezembro, 2016

Genetically modified (GM) crops have single or multiple genes introduced to obtain crop characteristics that cannot be obtained through conventional breeding. Pollen mediated gene flow from GM to non-GM crops causes some crops planted as non-GM to become GM, and this imposes economic losses on farmers who planted a non-GM crop but then have to sell the harvest on a GM market. The economic losses that result when both crops are grown together depend on the institutional arrangements and the type of property rights in place.

Simulating Littoral Trade: Modeling the Trade of Wine in the Bronze to Iron Age Transition in Southern France

Peer-reviewed publication
Março, 2016

The Languedoc-Roussillon region of southern France is well known today for producing full-bodied red wines. Yet wine grapes are not native to France. Additionally, wine was not developed indigenously first. In the 7th century B.C. Etruscan merchants bringing wine landed on the shores of the Languedoc and established trade relationships with the native Gauls, later creating local viticulture, and laying the foundation for a strong cultural identity of French wine production and setting in motion a multi-billion dollar industry.

Do Smallholder, Mixed Crop-Livestock Livelihoods Encourage Sustainable Agricultural Practices? A Meta-Analysis

Peer-reviewed publication
Março, 2016

As calls for bolstering ecosystem services from croplands have grown more insistent during the past two decades, the search for ways to foster these agriculture-sustaining services has become more urgent. In this context we examine by means of a meta-analysis the argument, proposed by Robert McC. Netting, that small-scale, mixed crop-livestock farming, a common livelihood among poor rural peoples, leads to environmentally sustainable agricultural practices.

How Land Concessions Affect Places Elsewhere: Telecoupling, Political Ecology, and Large-Scale Plantations in Southern Laos and Northeastern Cambodia

Peer-reviewed publication
Junho, 2015
Vietnam
Laos
Cambodja

Over the last decade considerable research has been conducted on the development and the impacts of large-scale economic land concessions for plantations in Laos and Cambodia. These studies have variously illustrated that concessions frequently result in serious negative impacts on local people and the environment, often leading to dramatic transformations of landscapes and livelihoods. As important as this research has been, these studies have largely focused on the immediate impacts of the “enclosure” process associated with gaining access to land by investors.

Investigating Impacts of Alternative Crop Market Scenarios on Land Use Change with an Agent-Based Model

Peer-reviewed publication
Dezembro, 2015

We developed an agent-based model (ABM) to simulate farmers’ decisions on crop type and fertilizer application in response to commodity and biofuel crop prices. Farm profit maximization constrained by farmers’ profit expectations for land committed to biofuel crop production was used as the decision rule. Empirical parameters characterizing farmers’ profit expectations were derived from an agricultural landowners and operators survey and integrated in the ABM.

Analyzing Vegetation Change in an Elephant-Impacted Landscape Using the Moving Standard Deviation Index

Peer-reviewed publication
Março, 2014
Botswana

Northern Botswana is influenced by various socio-ecological drivers of landscape change. The African elephant (Loxodonta africana) is one of the leading sources of landscape shifts in this region. Developing the ability to assess elephant impacts on savanna vegetation is important to promote effective management strategies. The Moving Standard Deviation Index (MSDI) applies a standard deviation calculation to remote sensing imagery to assess degradation of vegetation.

Ecologies of Scale: Multifunctionality Connects Conservation and Agriculture across Fields, Farms, and Landscapes

Peer-reviewed publication
Setembro, 2014

Agroecology and landscape ecology are two land-use sciences based on ecological principles, but have historically focused on fine and broad spatial scales, respectively. As global demand for food strains current resources and threatens biodiversity conservation, concepts such as multifunctional landscapes and ecologically-analogous agroecosystems integrate ecological concepts across multiple spatial scales.

Beyond Awareness and Self-Governance: Approaching Kavango Timber Users’ Real-Life Choices

Peer-reviewed publication
Setembro, 2013

Targeted illegal harvesting of hardwood in the woodland of Namibia’s Kavango region threatens forest stands. In a transforming setting, where wood is increasingly traded through value chains on a globalized market, local harvesters have complex incentives but also a crucially important position. Sustainability largely depends on their choices. Such choices are being influenced by awareness campaigns and decentralized forest management, which are being lauded and supported.

Interdependences between Smallholder Farming and Environmental Management in Rural Malawi: A Case of Agriculture-Induced Environmental Degradation in Malingunde Extension Planning Area (EPA)

Peer-reviewed publication
Junho, 2013

The objective of this article was to develop a deeper understanding of the interdependences between smallholder farming and the state of environmental management in rural Malawi. We examined the agricultural local governance framework in Malingunde Extension Planning Area (EPA), its contribution to food security and how it conflicts with overall land and forest resources management. The charcoal production process was discussed in line with its implications for agricultural production and environmental sustainability.

Allocation or appropriation? How spatial and temporal fragmentation of land allocation policies facilitates land grabbing in Northern Laos

Institutional & promotional materials
Dezembro, 2015
Laos

The Lao Land and Forest Allocation Policy (LFAP) was intended to provide clearer property rights for swidden farmers living in mountainous areas. These lands are legally defined as “State” forests but are under various forms of customary tenure. The policy involves demarcating village territorial boundaries, ecological zoning of lands within village territories, and finally allocating a limited number of individual land parcels to specific households for farming.
