Due to their long-term dual structures and rapid urbanization, cities and villages in developing countries are undergoing the challenges of urban-rural integration and ecological security. This study aims to determine the pattern of urban-rural spatial structures under the circumstances of ecological security in the future to promote the integrated, coordinated, green, and sustainable development of urban-rural spaces.

Restoration of marginal and degraded lands is essential for regaining biodiversity and ecosystems services, and thereby attaining UN-Sustainable Development Goals. During the last few decades, many fast growing and hardy trees have been introduced worldwide to restore the marginal and degraded lands for ecosystem stability. Unfortunately, most of these introduced species have become invasive and invaded the nearby productive systems, leading to significant biodiversity loss and land degradation.

In this study, we measured and characterized the relative dielectric constant of mineral soils over the 0.3–3.0 frequency range, and compared our measurements with values of three dielectric constant simulation models (the Wang, Dobson, and Mironov models). The interrelationship between land cover and soil texture with respect to the dielectric constant was also investigated. Topsoil samples (0–10 cm) were collected from homogenous areas based on a land unit map of the study site, located in the Gamsar Plain in northern Iran.

Rural livelihoods, which are basic human activities, have long interacted with the environment. In light of the complexity of the human–environment system, more interdisciplinary analyses from geographical, environmental, and social sciences are needed. Using qualitative and quantitative methods from social, environmental, and geographical sciences, this study conducted a geographical regionalization and a comparative analysis of rural livelihoods in different zones in the Loess Plateau to explore the relationship between rural livelihoods and the environment.

Normative guidelines for addressing project-induced displacement and resettlement have been successful in coercing companies and practitioners to comply with international standards and local requirements. However, good practice has not always been effectively implemented, leading to reduced social wellbeing of people in local communities. We assess how the reciprocal relationships between institutional norms and practitioners’ situated perspectives about company-community interactions can improve social management practice.

This study evaluated the effect of Land Use and Land Cover (LULC) dynamics on the value of ecosystem services in Abaya-Chamo basin over 1985–2050. The main objectives of the study were to estimate the value of ecosystem services of Abaya-Chamo basin using local and global ecosystem service value coefficients, assess how it changes over time, and develop tools to inform policy and public decision-making to protect lands and waters in the region.

This is a case about innovative approach of Boonrueng wetland forest conservation against land conversion for Special Economic Zone. Boonrueng wetland forest is the largest seasonal flooded forest in the Ing watershed located in the North of Thailand. It provides the high ecological functions and qualities of the tributary in the downstream Ing River, out-flowing into the Mekong River. The conversion of land for the economic regionalization in Chiang Khong district is geared up in 2015 and Boonrueng wetland forest was identified as an area for Special Economic Zone.
