Changes in Vegetation of Flooded Savannas Subject to Cattle Grazing and Fire in Plains of Colombia

Peer-reviewed publication
февраля, 2021
Bosnia and Herzegovina
Colombia
United States of America

Cattle grazing and fire are common types of management on natural ecosystems, generating several threats to the conservation of native vegetation (e.g., changes in species richness, cover, and abundance, mainly of bovine-palatable species). In this work, we analysed the response of the structure and composition of vegetation managed with different cattle stocking rates and fire in the savanna ecosystems of Colombia. The study was located in the eastern area of the Llanos region, where savannas were subjected to grazing and burning.

Which Traits Influence Bird Survival in the City? A Review

Peer-reviewed publication
февраля, 2021
Global

Urbanization poses a major threat to biodiversity worldwide. We focused on birds as a well-studied taxon of interest, in order to review literature on traits that influence responses to urbanization. We review 226 papers that were published between 1979 and 2020, and aggregate information on five major groups of traits that have been widely studied: ecological traits, life history, physiology, behavior and genetic traits. Some robust findings on trait changes in individual species as well as bird communities emerge.

Assessing Tradeoffs between Development and Conservation: A Case of Land Use Change in a National Park of Korea

Peer-reviewed publication
февраля, 2021
Norway
Democratic People's Republic of Korea
United States of America

Protected areas are places that provide diverse ecosystem services, including cultural ecosystem services. At the same time, the development and unbalanced use of natural resources in protected areas often create environmental threats and social conflicts. This study estimates the economic value of environmental consequences derived from the construction of an airport in a national park in Korea.

Toward a New Urban Cycle? A Closer Look to Sprawl, Demographic Transitions and the Environment in Europe

Peer-reviewed publication
февраля, 2021
Europe

Urban growth is a largely debated issue in social science. Specific forms of metropolitan expansion—including sprawl—involve multiple and fascinating research dimensions, making mixed (quali-quantitative) analysis of this phenomenon particularly complex and challenging at the same time. Urban sprawl has attracting the attention of multidisciplinary studies defining nature, dynamics, and consequences that dispersed low-density settlements are having on biophysical and socioeconomic contexts worldwide.

Proximate and Underlying Deforestation Causes in a Tropical Basin through Specialized Consultation and Spatial Logistic Regression Modeling

Peer-reviewed publication
февраля, 2021
Mexico
United States of America

The present study focuses on identifying and describing the possible proximate and underlying causes of deforestation and its factors using the combination of two techniques: (1) specialized consultation and (2) spatial logistic regression modeling. These techniques were implemented to characterize the deforestation process qualitatively and quantitatively, and then to graphically represent the deforestation process from a temporal and spatial point of view. The study area is the North Pacific Basin, Mexico, from 2002 to 2014.

Forest Disturbance Types and Current Analogs for Historical Disturbance-Independent Forests

United States of America

Forest classifications by disturbance permit designation of multiple types of both old growth forests and shorter-lived forests, which auto-replace under severe disturbance, and also identification of loss of the disturbance type and associated forest. Historically, fire and flooding disturbance regimes, or conversely, infrequent disturbance, produced unique forests such as disturbance-independent forests of American beech (Fagus grandifolia), eastern hemlock (Tsuga canadensis), and sugar maple (Acer saccharum) in the Eastern United States.

Analysis on the Effect of the Mobility of Combustion Vehicles in the Environment of Cities and the Improvement in Air Pollution in Europe: A Vision for the Awareness of Citizens and Policy Makers

Today, the design and remodeling of urban environments is being sought in order to achieve green, healthy, and sustainable cities. The effect of air pollution in cities due to vehicle combustion gases is an important part of the problem. Due to the indirect effect caused by the Covid-19 pandemic, political powers in Europe have imposed confinement measures for citizens by imposing movement restrictions in large cities. This indirect measure has given us a laboratory to show how the reduction in vehicle circulation affects in a short time the levels of air pollution in cities.

Framework for Climate Change Adaptation of Agriculture and Forestry in Mediterranean Climate Regions

Peer-reviewed publication
февраля, 2021
Afghanistan

Planning the adaptation of agriculture and forestry landscapes to climate change remains challenging due to the need for integrating substantial amounts of information. This information ranges from climate scenarios, geographical site information, socio-economic data and several possible adaptation measures. Thus, there is an urgent need to have a framework that is capable of organizing adaptation strategies and measures in the agriculture and forestry sectors in Mediterranean climatic regions.

Cultivated Land Use Layout Adjustment Based on Crop Planting Suitability: A Case Study of Typical Counties in Northeast China

Peer-reviewed publication

China
Russia
United States of America

Cultivated land use layout adjustment (CLULA) based on crop planting suitability is the refinement and deepening of land use transformation, which is of great significance for optimizing the allocation of cultivated land resources and ensuring food security. At present, people rarely consider the land suitability of crops when using cultivated land, resulting in an imbalance between crop distribution and resource conditions such as water, heat, and soil, and adversely affects the ecological security and utilization efficiency of cultivated land.

Emerging from Below? Understanding the Livelihood Trajectories of Smallholder Livestock Farmers in Eastern Cape Province, South Africa

Peer-reviewed publication

Southern Africa

In the context of current agrarian reform efforts in South Africa, this paper analyses the livelihood trajectories of ‘emergent’ farmers in Eastern Cape Province. We apply a rural livelihoods framework to 60 emergent cattle farmers to understand the different capitals they have drawn upon in transitioning to their current class positions and associated vulnerability. The analysis shows that, for the majority of farmers, no real ‘transition’ from subsistence farming has occurred.

Bird Diversity Unconsciously Increases People’s Satisfaction with Where They Live

United States of America

There is growing evidence that exposure to nature increases human well-being, including in urban areas. However, relatively few studies have linked subjective satisfaction to objective features of the environment. In this study we explore the links among objective environmental features (tree cover, water, and bird diversity) and subjective judgements of satisfaction. We surveyed residents of Ottawa, Canada (n = 1035) about their satisfaction with their local neighbourhoods.

Influence of Urban Sprawl on Microclimate of Abbottabad, Pakistan

Peer-reviewed publication
февраля, 2021
Pakistan

Urban centers are expanding rapidly due to quickly-increasing population which results in microclimate change due to lack of urban planning. Factors like degradation of green areas, trees, and vegetation are defining a new regime of urban environment giving rise to a lack of drinking water and lowering water tables. Consequently, unplanned urban sprawl with all its varied facets is having adverse impacts on the environment. Rapid variations in some of its climatic factors in the immediate vicinity are alarming and need to redress at war footings.
