The “New Transamazonian Highway”: BR-319 and Its Current Environmental Degradation

Peer-reviewed publication
Décembre, 2021
Brazil

The Brazilian government intends to complete the paving of the BR-319 highway, which connects Porto Velho in the deforestation arc region with Manaus in the middle of the Amazon Forest. This paving is being planned despite environmental legislation, and there is concern that its effectiveness will cause additional deforestation, threatening large portions of forest, conservation units (CUs), and indigenous lands (ILs) in the surrounding areas.

Geotechnology Applied to Analysis of Vegetation Dynamics and Occurrence of Forest Fires on Indigenous Lands in Cerrado-Amazonia Ecotone

Peer-reviewed publication
Décembre, 2021
Brazil

The Cerrado-Amazonia Ecotone is one of the largest ecosystems in Brazil and is internationally considered a biodiversity hotspot. The occurrence of fires is common in these areas, directly affecting biomass losses and the reduction of vegetative vigor of forest typologies. Information obtained through remote sensing and geoprocessing can assist in the evaluation of vegetation behavior and its relation to the occurrence of forest fires.

Highway Network and Fire Occurrence in Amazonian Indigenous Lands

Peer-reviewed publication
Décembre, 2021
Brazil

The construction and expansion of highways aiming to improve the integration of the most isolated regions in Brazil facilitated the access to many inhabited areas in the Amazon biome, but had as a consequence assisted the degradation of many of these regions. Over the last two decades, we have observed in this biome a gradual diversification and intensification of land uses through vegetation loss and an increase in fire associated with deforestation and an increase in grazing areas.

Indigenous Peoples’ Food Systems and Biocultural Heritage: Addressing Indigenous Priorities Using Decolonial and Interdisciplinary Research Approaches

Peer-reviewed publication
Décembre, 2021
Kenya
China
India

The food systems and territories of Indigenous Peoples sustain much of the world’s biodiversity, cultivated and wild, through agroecological practices rooted in Indigenous cosmovision and cultural and spiritual values. These food systems have a critical role to play in sustainability transformations but are widely threatened and have received limited research attention. This paper presents the results of four virtual workshops with Indigenous Peoples: a global workshop and local workshops with communities in coastal Kenya, northeast India and southwest China.

Soil Management in Indigenous Agroforestry Systems of Guarana (Paullinia cupana Kunth) of the Sateré-Mawé Ethnic Group, in the Lower Amazon River Region

Peer-reviewed publication
Décembre, 2021
Global

The Sateré-Mawé Brazilian indigenous people cultivate the guarana liana in biodiverse agroforests that incorporate many species, mainly trees, and produce food, medicines, fuel and income. The objective of this study was to evaluate the soil fertility in nineteen indigenous guarana agroforestry systems (AFSs) compared with areas of adjacent forests in the Andirá–Marau Indigenous Land—an ancestral territory of the Sateré-Mawé people. Soils in both locations showed low natural fertility, with levels of most macronutrients below the minimum agronomic reference levels.

Possession of Site: Another Layer of Complexity in Road Construction

Peer-reviewed publication
Décembre, 2021
Global

Time is money, and it is crucial to accelerate road construction to improve the accessibility and connectivity of infrastructure. Prolonged periods of project implementation lead to delays and cost overruns, and further delays could destabilize the construction industry, causing an economic slowdown. This study explores the causes of delay in giving site possession, a topic that has received little explicit attention. The authors qualitatively identified the causes of delayed site possession from 15 project case studies.

Modeling the Carbon Sequestration Potential of Multifunctional Agroforestry-Based Phytoremediation (MAP) Systems in Chinandega, Nicaragua

Peer-reviewed publication
Décembre, 2021
Nicaragua

Global sustainability challenges associated with increasing resource demands from a growing population call for resource-efficient land-use strategies that address multiple sustainability issues. Multifunctional agroforestry-based phytoremediation (MAP) is one such strategy that can simultaneously capture carbon, decontaminate soils, and provide diverse incomes for local farmers. Chinandega, Nicaragua, is a densely populated agricultural region with heavily polluted soils.

An Expert Approach to an Assessment of the Needs of Land Consolidation within the Scope of Improving Water Resource Management

Peer-reviewed publication
Décembre, 2021
Poland

The objective of this study is to present the approach to assess needs of land consolidation to prepare rural areas for proper water resource management. The study presented links of water management with land consolidation, which is a new approach in rural development planning in Central Europe. The results of this research are presented in the form of a needs assessment matrix for water retention.

Response of Potential Indicators of Soil Quality to Land-Use and Land-Cover Change under a Mediterranean Climate in the Region of Al-Jabal Al-Akhdar, Libya

Peer-reviewed publication
Décembre, 2021
Libya

Conversion of native lands into agricultural use, coupled with poor land management practices, generally leads to changes in soil properties. Understanding the undesirable effects of land-use and land-cover (LULC) changes on soil properties is essential when planning for sustainable land management.

A Study on the Rationality of Land Use Change in the Dianchi Basin during the Last 40 Years under the Background of Lake Revolution

Peer-reviewed publication
Décembre, 2021
China

(1) Background: Dianchi Lake is the largest freshwater plateau lake in southwest China. Since the 1970s, with the large-scale lake reclamation and rapid urbanization, the land use/cover of the Dianchi Basin has changed dramatically, directly hindering the sustainable development of the watershed. It is urgent to study the rationality of land use change in order to promote the “win-win” of eco-environment protection and sustainable economic and social development in Dianchi Basin.

Analyzing Spatio-Temporal Change in Ecosystem Quality and Its Driving Mechanism in Henan Province, China, from 2010 to 2020

Peer-reviewed publication
Décembre, 2021
Global

Henan Province is an important ecological barrier in the middle and lower reaches of the Yellow River. It is of great significance to study its ecosystem quality and the driving mechanisms behind this in order to realize ecological conservation and high-quality development in the Yellow River Basin.

Extraction of Rural Residential Land from Very-High Resolution UAV Images Using a Novel Semantic Segmentation Framework

Peer-reviewed publication
Décembre, 2021
China

Accurate recognition and extraction of rural residential land (RRL) is significant for scientific planning, utilization, and management of rural land. Very-High Resolution (VHR) Unmanned Aerial Vehicle (UAV) images and deep learning techniques can provide data and methodological support for the target. However, RRL, as a complex land use assemblage, exhibits features of different scales under VHR images, as well as the presence of complex impervious layers and backgrounds such as natural surfaces and tree shadows in rural areas.
