The Uneven Influence of Climate Trends and Agricultural Policies on Maize Production in the Yucatan Peninsula, Mexico

Peer-reviewed publication
Septiembre, 2018
México

Maize is an important staple crop in Mexico, and the recent intensification of climate variability, in combination with non-climatic forces, has hindered increases in production, especially for smallholder farmers. This article demonstrates the influence of these drivers on maize production trends in the three states of the Yucatan Peninsula using a mixed methods approach of climatic analysis and semi-structured interviews.

Setting and Implementing Standards for Management of Wild Tigers

Peer-reviewed publication
Septiembre, 2018
Global

Tiger numbers have collapsed so dramatically that conservationists are adopting a strategy of securing populations in priority conservation landscapes. This includes improving management effectiveness in these sites. The Conservation Assured|Tiger Standards (CA|TS) are designed to help ensure effectiveness and provide a benchmark against which to measure progress.

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.

Underground Space Utilization in the Urban Land-Use Planning of Casablanca (Morocco)

Peer-reviewed publication
Diciembre, 2018
Marruecos

With the rapid rate of population growth and economic development, cities face enormous challenges that require both optimal and integrated solutions to meet the needs of growth and to protect the environment and sustainable development. These urban dynamics, which change over time, extend not only horizontally and upward, but also downward. Thus, underground space has been utilized increasingly to relieve the urban surface and to ensure the exploitation of underground resources.

Assessing Stormwater Nutrient and Heavy Metal Plant Uptake in an Experimental Bioretention Pond

Peer-reviewed publication
Diciembre, 2018
Italia

With the purpose to study a solution based on Sustainable Urban Drainage Systems (SUDS) to reduce and treat stormwater runoff in urban areas, a bioretention pond (BP) was realized in the Agripolis campus of the University of Padova, Italy. The BP collected overflow water volumes of the rainwater drainage system of a 2270 m2 drainage area consisting almost entirely of impervious surfaces. Sixty-six Tech-IA® floating elements, supporting four plants each, were laid on the water surface. Eleven species of herbaceous perennial helophyte plants, with ornamental features, were used and tested.

The Economic Centrality of Urban Centers in the Medieval Peloponnese: Late 11th–Mid-14th Centuries

Peer-reviewed publication
Diciembre, 2018
Global

The Peloponnese, a province of the Byzantine Empire in the 11th and 12th centuries, was divided into three distinct political entities after 1204: the Frankish Principality of Achaia, the Venetian colonies of Modon and Coron, and the Byzantine lands in the southeast. The number and size of cities in the Peloponnese during the 11th and 12th centuries expanded, and the establishment of the new political entities of the 13th century did not hinder the development of its urban centers. New urban centers appeared, and the dynamics of the old urban centers witnessed a major shift.

Characterizing the Spatial and Temporal Availability of Very High Resolution Satellite Imagery in Google Earth and Microsoft Bing Maps as a Source of Reference Data

Peer-reviewed publication
Diciembre, 2018
India
Estados Unidos de América
Europa

Very high resolution (VHR) satellite imagery from Google Earth and Microsoft Bing Maps is increasingly being used in a variety of applications from computer sciences to arts and humanities. In the field of remote sensing, one use of this imagery is to create reference data sets through visual interpretation, e.g., to complement existing training data or to aid in the validation of land-cover products. Through new applications such as Collect Earth, this imagery is also being used for monitoring purposes in the form of statistical surveys obtained through visual interpretation.

The Emergence of Landscape Urbanism: A Chronological Criticism Essay

Peer-reviewed publication
Diciembre, 2018
Global

Scholars and practitioners have great interest in topics related to spatial patterns and the organization and properties of space. Landscape urbanism is one of these topics of interest. This essay, in the form of chronological criticism, presents a broad historical overview of the rise of landscape urbanism, primarily from a landscape architectural/geographical/ecological perspective, comparing the normative theories derived in the Western traditions embedded in urban design and architecture with the general values of landscape urbanism.

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.

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.
