Comparison of Statistical Approaches for Modelling Land-Use Change

Peer-reviewed publication
Diciembre, 2018
Global

Land-use change can have local-to-global environment impacts such as loss of biodiversity and climate change as well as social-economic impacts such as social inequality. Models that are built to analyze land-use change can help us understand the causes and effects of change, which can provide support and evidence to land-use planning and land-use policies to eliminate or alleviate potential negative outcomes.

Navigating Multiple Tensions for Engaged Praxis in a Complex Social-Ecological System

Peer-reviewed publication
Diciembre, 2018
Sudáfrica
África austral

Innovative, pragmatic approaches are needed to support sustainable livelihoods and landscape management in complex social-ecological systems (CSES) such as river catchments. In the Tsitsa River Catchment, South Africa, researchers and natural resource managers have come together to apply such innovative approaches. Since CSES are characterised by uncertainty and surprise, understanding and managing them requires a commitment to reflexive praxis and transdisciplinarity.

Market-Based Conservation for Better Livelihoods? The Promises and Fallacies of REDD+ in Tanzania

Peer-reviewed publication
Diciembre, 2018
Tanzania
África

Governments, multilateral organisations, and international conservation NGOs increasingly frame nature conservation in terms that emphasise the importance of technically managing and economically valuing nature, and introducing markets for ecosystem services. New mechanisms, such as REDD+, have been incorporated in national-level policy reforms, and have been piloted and implemented in rural project settings across the Global South.

A Model for Estimating the Vegetation Cover in the High-Altitude Wetlands of the Andes (HAWA)

Peer-reviewed publication
Enero, 2019
Chile

The natural salt meadows of Tilopozo in the hyperarid, Atacama Desert of northern Chile, which are located at approximately 2800 m above sea level, are under pressure from industrial activity, and cultivation and grazing by local communities. In this research, the land surface covered by salt meadow vegetation was estimated from normalized difference vegetation indices (NDVI) derived from Landsat Thematic Mapper (TM), Enhanced Thematic Mapper (ETM+) and Operational Land Imager (OLI) data from 1985 to 2016.

Gender, Educational Attainment, and Farm Outcomes in New Zealand

Peer-reviewed publication
Enero, 2019
Nueva Zelandia

Empirical studies of farm outcomes that rely on survey data often find important roles for education and gender. However, relatively few studies consider either field of study or gender of the decision maker (as opposed to gender of the survey respondent). This paper evaluates how the field of education and gender of decision makers correlate with profitability, farm management, future intentions, risk and norms, and adoption of novel technologies in New Zealand, explicitly accounting for the fact that many farming households make decisions jointly.

New 1 km Resolution Datasets of Global and Regional Risks of Tree Cover Loss

Peer-reviewed publication
Enero, 2019
Global

Despite global recognition of the social, economic and ecological impacts of deforestation, the world is losing forests at an alarming rate. Global and regional efforts by policymakers and donors to reduce deforestation need science-driven information on where forest loss is happening, and where it may happen in the future.

Net Global Warming Potential of Spring Wheat Cropping Systems in a Semiarid Region

Peer-reviewed publication
Febrero, 2019
Global
América Septentrional

Investigations of global warming potential (GWP) of semiarid cropping systems are needed to ascertain agriculture’s contributions to climate regulation services. This study sought to determine net GWP for three semiarid cropping systems under no-tillage management in the northern Great Plains of North America: spring wheat (Triticum aestivum L.)—fallow (SW-F), continuous spring wheat (CSW) and spring wheat—safflower (Carthamus tinctorius L.)—rye (Secale cereale L.) (SW-S-R).

Globalization and Biodiversity Conservation Problems: Polycentric REDD+ Solutions

Peer-reviewed publication
Febrero, 2019
Global

Protected areas are considered the cornerstone of biodiversity conservation, but face multiple problems in delivering this core objective. The growing trend of framing biodiversity and protected area values in terms of ecosystem services and human well-being may not always lead to biodiversity conservation. Although globalization is often spoken about in terms of its adverse effects to the environment and biodiversity, it also heralds unprecedented and previously inaccessible opportunities linked to ecosystem services.

Making It Spatial Makes It Personal: Engaging Stakeholders with Geospatial Participatory Modeling

Peer-reviewed publication
Febrero, 2019
Global

Participatory research methods are increasingly used to collectively understand complex social-environmental problems and to design solutions through diverse and inclusive stakeholder engagement. But participatory research rarely engages stakeholders to co-develop and co-interpret models that conceptualize and quantify system dynamics for comparing scenarios of alternate action. Even fewer participatory projects have engaged people using geospatial simulations of dynamic landscape processes and spatially explicit planning scenarios.

Ecosystem Productivity and Water Stress in Tropical East Africa: A Case Study of the 2010–2011 Drought

Peer-reviewed publication
Marzo, 2019
África oriental

Characterizing the spatiotemporal patterns of ecosystem responses to drought is important in understanding the impact of water stress on tropical ecosystems and projecting future land cover transitions in the East African tropics. Through the analysis of satellite measurements of solar-induced chlorophyll fluorescence (SIF) and the normalized difference vegetation index (NDVI), soil moisture, rainfall, and reanalysis data, here we characterize the 2010–2011 drought in tropical East Africa.
