Human interventions in natural areas as a change in land use have led to a domino effect of anomalies and then environmental hazards. These extensive and cumulative changes in land cover and land use have manifested themselves in the form of anomalies such as the formation of severe runoff, soil erosion, the spread of desertification, and salinization of the soil. The main purpose of this study...
Urban development with sustainable urban forms in high-density low-income Asian countries is a great challenge in the context of acute land scarcity. Though the model of compact cities is a natural choice for high-density urbanizing Asia, fierce competition for limited urban land resources without effective governance often results in an unfavorable form of densification and urban compaction. F...

Projects intended to upgrade these settlements have not been highly successful. In Kenya, project beneficiaries receiving land under individual titles sell or lose their land rights. This transfer of property is seen as stimulating informal settlement construction an...

Colonization of land by plants was a major transition on Earth, but the developmental and genetic innovations required for this transition remain unknown. Physiological studies and the fossil record strongly suggest that the ability of the first land plants to form symbiotic associations with beneficial fungi was one of these critical innovations. In angiosperms, genes required for the percepti...
