Understanding Landscape Influences on Aquatic Fauna across the Central and Southern Appalachians

Peer-reviewed publication
Janeiro, 2020
Global

For the success of aquatic conservation efforts, it is imperative for there to be an understanding of the influences multiple stressors across the landscape have on aquatic biota, as it provides an understanding of spatial patterns and informs regional stakeholders. The central and southern Appalachians contain biodiversity hotspots for aquatic fauna. Therefore, we sought to create a comprehensive multimetric model that is based on the influence of abiotic factors on fish and aquatic macroinvertebrates that could predict watershed quality.

Hydrological Control of Vegetation Greenness Dynamics in Africa: A Multivariate Analysis Using Satellite Observed Soil Moisture, Terrestrial Water Storage and Precipitation

Peer-reviewed publication
Janeiro, 2020
Africa

Vegetation activity in many parts of Africa is constrained by dynamics in the hydrologic cycle. Using satellite products, the relative importance of soil moisture, rainfall, and terrestrial water storage (TWS) on vegetation greenness seasonality and anomaly over Africa were assessed for the period between 2003 and 2015. The possible delayed response of vegetation to water availability was considered by including 0–6 and 12 months of the hydrological variables lagged in time prior to the vegetation greenness observations.

Effects of Soil Bund and Stone-Faced Soil Bund on Soil Physicochemical Properties and Crop Yield Under Rain-Fed Conditions of Northwest Ethiopia

Peer-reviewed publication
Janeiro, 2020
Ethiopia

Research-based evidence on the effects of soil and water conservation practices (SWCPs) on soil physicochemical properties and crop yield is vital either to adopt the practices or design alternative land management strategies. Thus, this study was conducted to evaluate the effects of about 10-year-old soil bund (SB) and stone-faced soil bund (SFSB) structures on selected soil physicochemical properties, slope gradient, barley grain yield, and yield components in the Lole watershed, in the northwest highlands of Ethiopia.

Short Term Effects of Revegetation on Labile Carbon and Available Nutrients of Sodic Soils in Northeast China

Peer-reviewed publication
Janeiro, 2020
China

In response to land degradation and the decline of farmers’ income, some low quality croplands were converted to forage or grassland in Northeast China. However, it is unclear how such land use conversions influence soil nutrients. The primary objective of this study was to investigate the influences of short term conversion of cropland to alfalfa forage, monoculture Leymus chinensis grassland, monoculture Leymus chinensis grassland for hay, and successional regrowth grassland on the labile carbon and available nutrients of saline sodic soils in northeastern China.

The Role of Vegetation in the Morphological Decoding of Lisbon (Portugal)

Peer-reviewed publication
Janeiro, 2020
Portugal

In the academic context, especially in the fields of architecture, landscape architecture, and urbanism, urban form studies are assumed to be a vehicle for reflection on the built and unbuilt city. This essay aims to challenge the most common and stabilized morphological approaches in the city reading process, invoking vegetation and its role as an element of urban composition that is recurrently left out of it.

Driving Factors of the Industrial Land Transfer Price Based on a Geographically Weighted Regression Model: Evidence from a Rural Land System Reform Pilot in China

Peer-reviewed publication
Janeiro, 2020
China

More and more studies on land transfer prices have been carried out over time. However, the influencing factors of the industrial land transfer price from the perspective of spatial attributes have rarely been explored. Selecting 25 towns as the basic research unit, based on industrial land transfer data, this paper analyzes the influencing factors of the price distribution of industrial land in Dingzhou City, a rural land system reform pilot in China, by using a geographically weighted regression (GWR) model.

Determinants of Agricultural Infrastructure Construction in China: Based on the “Participation of Beneficiary Groups” Perspective

Peer-reviewed publication
Janeiro, 2020
China

Agricultural infrastructure is a typical public good, and it plays an important role in rural development. The “participation of beneficiary groups (PBG)” system is encouraged by government to supply village level public goods in China. Based on micro survey data from the village level in Jiangsu Province, this study analyzes the status of agricultural infrastructure construction and the promotion of PBG model and quantitatively analyzes the impact of different factors using an econometric model.

Pastoral Stone Enclosures as Biological Cultural Heritage: Galician and Cornish Examples of Community Conservation

Peer-reviewed publication
Janeiro, 2020
Europe

The role and importance of a built structure are closely related to the surrounding area, with interest in a given area having a concomitant effect on the relevance given to the constructions it may hold. Heritage interest in landscape areas has grown in recent times leading to a sound valorisation process. This connects with the recent concept of biological cultural heritage (BCH), or biocultural heritage (definition still in process), that can be understood as domesticated landscapes resulting from long-term biological and social relationships.

Knowledge flows: Farmers’ social relations and knowledge sharing practices in ‘Catchment Sensitive Farming’

Peer-reviewed publication
Dezembro, 2019
Estados Unidos

The move towards sustainable agriculture requires a more detailed understanding of farmers’ knowledge(s) and knowledge practices. Increasingly, it is important to understand not only what farmers understand, but how their knowledge practices incorporate others – especially given the emerging call for environmentally-orientated policy measures to move beyond an individual farmer focus. This paper considers how farmers engage with, utilise and share knowledge through a focus on the Catchment Sensitive Farming (CSF) initiative in the UK.

Perspectives on agriculturally used drained peat soils: Comparison of the socioeconomic and ecological business environments of six European regions

Peer-reviewed publication
Dezembro, 2019

Estados Unidos

In Northern, Eastern and Central European countries, peat soils drained for agriculture are a considerable source of greenhouse gas emissions. Since emissions from this source have high mitigation potential, they will likely be a focus of the European Union’s future climate goals. We describe and compare the similarities and differences in the socioeconomic and ecological business environment that policy makers, planners and farmers are confronted with when developing tailored proposals for low emission land use alternatives on peat land.

Reviewing First Nation land management regimes in Canada and exploring their relationship to community well-being

Peer-reviewed publication
Dezembro, 2019
Canadá
Território Britânico do Oceano Índico

The presented paper synthesizes and reviews the history of Fist Nation land management, forming the background of three land management regimes types; the Indian Act land management (IALM), First Nations land management (FNLM) and frameworks of self-government land management (SGLM). The three regimes are compared to the Community Well-Being (CWB) index, being a measure of socio-economic development of communities across Canada.

Hybrid land tenure administration in Dunoon, South Africa

Hybrid land tenure administration occurs in a number of South Africa’s state-subsidised housing projects and in the informal settlements from which the housing beneficiaries tend to be drawn. Ownership is the tenure form in most of these housing projects. Under ownership the law only recognises registered land transactions. Non-government tenure administration in Dunoon was organised by street and area committees that are part of the local South African National Civics Association (SANCO) branch, a community based organisation (CBO).
