Institutional Change on a Conservationist Frontier: Local Responses to a Grabbing Process in the Name of Environmental Protection

Peer-reviewed publication
Diciembre, 2019
Ecuador

In a wave of global conservationism, Ecuador established two large protected areas in its Amazon region in 1979. One of these is the Reserva de Producción Faunística Cuyabeno (RPFC), located in the northeastern corner of the country. Given that this land was previously managed as commons by local indigenous groups, the establishment of protected areas has had numerous consequences for these people. The research conducted comprised three months’ fieldwork in three of the affected Siona communities, primarily through the use of participant observation.

Village Level Provisioning Ecosystem Services and Their Values to Local Communities in the Peri-Urban Areas of Manila, The Philippines

Peer-reviewed publication
Diciembre, 2019
Filipinas

This study investigates different provisioning services in the peri-urban landscapes of Manila conurbation through a case study of two villages in the Jala-Jala municipality of the Laguna de Bay area in the Philippines. Laguna de Bay is an ecologically productive and important watershed for the urban and peri-urban areas of Manila for the provision of food, freshwater, and other materials. However, the lake and its ecosystem are under threat because of rapid urbanization and associated land-use changes.

Nested Interconnection: Transgressing Community-Based Natural Resource Management towards Innovating Collective Landscape Mobilization. A case of Boonrueng Wetland Forest Conservation against Land Conversion for Special Economic Zone in the North of Thail

Journal Articles & Books
Diciembre, 2018
Tailandia

This is a case about innovative approach of Boonrueng wetland forest conservation against land conversion for Special Economic Zone. Boonrueng wetland forest is the largest seasonal flooded forest in the Ing watershed located in the North of Thailand. It provides the high ecological functions and qualities of the tributary in the downstream Ing River, out-flowing into the Mekong River. The conversion of land for the economic regionalization in Chiang Khong district is geared up in 2015 and Boonrueng wetland forest was identified as an area for Special Economic Zone.

Applying a Systematic Review to Land Use Land Cover Change in Northern Upland Vietnam: The Missing Case of the Borderlands

Journal Articles & Books
Noviembre, 2015
Viet Nam

As Vietnam embraces the market economy, and a number of state policies promote reforestation and rural market integration, land use and land cover (LULC) changes are occurring in the country’s northern uplands in increasingly complex and fragmented ways. Yet understandings of the degree and consequences of LULC changes in this diverse agro-ecological region are incomplete. We conduct a systematic literature review of research reported in academic articles tracing and analysing LULC change in Vietnam’s northern regions.

REDD+ at the crossroads: Choices and tradeoffs for 2015 – 2020 in Laos

Policy Papers & Briefs
Diciembre, 2015
Laos

To date, REDD+ projects in Laos have made relatively conservative choices on driver engagement, focusing on smallholder-related drivers like shifting cultivation and small-scale agricultural expansion, to the exclusion of drivers like agro-industrial concessions, mining concessions and energy and transportation infrastructure. While these choices have been based on calculated decisions made in the context of project areas, they have created a pair of challenges that REDD+ practitioners must currently confront. The first is lost opportunity.

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.

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.

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.

Towards productive landscapes: Trade-offs in tree-cover and income across a matrix of smallholder agricultural land-use systems

Peer-reviewed publication
Diciembre, 2016
Bangladesh
Indonesia

One of the main causes of tropical forest loss is conversion to agriculture, which is constantly increasing as a dominant land cover in the tropics. The loss of forests greatly affects biodiversity and ecosystem services. This paper assesses the economic return from increasing tree cover in agricultural landscapes in two tropical locations, West Java, Indonesia and eastern Bangladesh. Agroforestry systems are compared with subsistence seasonal food-crop-based agricultural systems.

The 10 ​Science ​‘Must​ Knows’ ​on ​Climate ​Change

Diciembre, 2017
Global

It is undoubtedly a challenge for climate policy actors to identify reliable evidence to support sound decision-making processes for tackling climate issues effectively. Still, differentiating between fact and fiction, well-designed and invalid science, evidence- or interest-based arguments is precisely what determines the quality of climate policies.
