Measuring participation: Case studies on village land use planning in northern Lao PDR

Journal Articles & Books
Diciembre, 2011
Laos

In the early 1990s, the Lao government launched a nationwide Land Use Planning and Land Allocation programme in a bid to foster socio-economic development while protecting the environment. However, the programme has long been perceived as having negative impacts on rural livelihoods. A central criticism was that limited local participation results in unsustainable land use plans; consequently, the government introduced significant changes into the process to enhance participation.

Land degradation in the Lao PDR: Discourses and policy

Journal Articles & Books
Diciembre, 2010
Laos

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.

Land tenure and water rights in Thailand and Vietnam - challenges for ethnic minorities in mountainous forest regions

Journal Articles & Books
Diciembre, 2006
Tailandia
Viet Nam

Ethnic minorities in the mountainous forest regions of northern Thailand and northern Vietnam live in a particularly restrictive political, social and economic environment. Widespread degradation of land, water and forest resources has adverse effects on the livelihoods of these groups. Given the dramatically increasing scarcity of natural resources, regulation of resource access and allocation are becoming fundamental for the development of sustainable resource management, in which an active participation of the local population in planning and implementation is a crucial prerequisite.

Land Policy and Farming Practices in Laos

Journal Articles & Books
Diciembre, 2005
Laos

The government of Laos has identified the eradication of poverty as a priority. Given the primarily agricultural character of the country, it has selected land reform as a core policy to reach this goal. The policy has two major aims: to increase land tenure security in order to encourage farmer involvement in intensive farming, and to eliminate slash-and-burn agriculture to protect the environment in a country still rich in forest resources.

Accessing and Mobilizing “New” Data to Evaluate Emerging Environmental Impacts on Semi-Aquatic Mammals

Peer-reviewed publication
Septiembre, 2020
Canadá

This paper describes how knowledge mobilization evolved during a study that assessed a proposed increase in industrial water withdrawals from the Athabasca River in northern Alberta, Canada, and potential impacts on a suite of freshwater semi-aquatic mammals in the broader ecosystem. The oil sands region in northeastern Alberta faces various pressures that require rapid knowledge mobilization and decision making, while still acknowledging ecological sensitivities immediately downstream in the Peace-Athabasca Delta (PAD) in the Wood Buffalo National Park.

Spatial and Ecological Farmer Knowledge and Decision-Making about Ecosystem Services and Biodiversity

Peer-reviewed publication
Septiembre, 2020
Malawi

Amid climate change, biodiversity loss and food insecurity, there is the growing need to draw synergies between micro-scale environmental processes and practices, and macro-level ecosystem dynamics to facilitate conservation decision-making. Adopting this synergistic approach can improve crop yields and profitability more sustainably, enhance livelihoods and mitigate climate change.

Spatial Variation in Environmental Impacts of Sugarcane Expansion in Brazil

Peer-reviewed publication
Septiembre, 2020
Brasil
Estados Unidos de América

In the past decades, sugarcane production in Brazil has expanded rapidly to meet increasing ethanol demand. The large majority of this expansion occurred in Sao Paulo state. We used an integrated approach considering location-specific biophysical characteristics to determine the environmental impacts of sugarcane expansion and their spatial variation in Sao Paulo state (2004–2015). The included environmental impacts are greenhouse gas (GHG) emissions, biodiversity, soil erosion, and water quantity.

Challenging a Global Land Surface Model in a Local Socio-Environmental System

Peer-reviewed publication
Septiembre, 2020
Estados Unidos de América
Noruega

Land surface models (LSMs) predict how terrestrial fluxes of carbon, water, and energy change with abiotic drivers to inform the other components of Earth system models. Here, we focus on a single human-dominated watershed in southwestern Michigan, USA. We compare multiple processes in a commonly used LSM, the Community Land Model (CLM), to observational data at the single grid cell scale.

Environmental Regulations, the Industrial Structure, and High-Quality Regional Economic Development: Evidence from China

Peer-reviewed publication
Diciembre, 2020
China
Rusia
Estados Unidos de América

Environmental regulation is an important means of restraining enterprises and protecting the environment. Rationalization of environmental regulatory policies can promote high-quality regional economic development. The optimization and upgrading of the industrial structure has an intermediary effect on the impact of environmental regulations on the high-quality development of the regional economy.

Climate, energy and environmental policies in agriculture: Simulating likely farmer responses in Southwest Germany

Peer-reviewed publication
Junio, 2015
Global

Agriculture in many industrialized countries is subject to a wide range of policy interventions that seek to achieve ambitious climate, energy and environment-related objectives. Increasing support for the generation of climate-friendly, renewable energy in agriculture, however, may lead to potential conflicts with agri-environmental policies aimed at land use extensification and landscape preservation.

Exploring land use/land cover changes, drivers and their implications in contrasting agro-ecological environments of Ethiopia

Peer-reviewed publication
Agosto, 2019
Etiopía

This study examined the trends, driving factors, and implications of land use/land cover (LULC) dynamics over the past 35 years (1982–2017) in three watersheds of the drought-prone areas that represent different agro-ecologies of Upper Blue Nile basin, Ethiopia: Guder (highland), Aba Gerima (midland), and Debatie (lowland). The changes in LULC were analyzed by integrating field observations, remote-sensing data (aerial photographs [1: 50,000 scale] and very high resolution [0.5–3.2 m] satellite images), and geographic information systems.

Trade-offs between high class land and development: Recent and future pressures on Auckland's valuable soil resources

Peer-reviewed publication
Junio, 2014
Nueva Zelandia

Sustainable land management is essential to meeting the global challenge of securing soil and water resources that can support an ever increasing population. In Auckland, New Zealand's largest city, population growth is forecast to increase from 1.5 to 2.5 million by 2040 which will put immense pressure on the region's soil resources.
