The recent rapid population and economic growth in Southeast Asia has brought about drastic socio-economic changes, such as urbanization and an agricultural shift. Urbanization consists of concentrating a population from a rural to an urban area and expanding urban areas, which pushes farmland outward.
Peatlands are carbon-rich ecosystems that cover just three per cent of Earth's land surface, but store one-third of soil carbon. Peat soils are formed by the build-up of partially decomposed organic matter under waterlogged anoxic conditions. Most peat is found in cool climatic regions where unimpeded decomposition is slower, but deposits are also found under some tropical swamp forests.
Assessment of the progress of the Aichi Biodiversity Targets set by the Convention on Biological Diversity (CBD) and the safeguarding of ecosystems from the perverse negative impacts caused by Reducing Emissions from Deforestation and Forest Degradation Plus (REDD+) requires the development of spatiotemporally robust and sensitive indicators of biodiversity and ecosystem health.
Land cover and forest mapping supports decision makers in the course of making informed decisions for implementation of sustainable conservation and management plans of the forest resources and environmental monitoring. This research examines the value of integrating of ALOS PALSAR and Landsat data for improved forest and land cover mapping in Northern Tanzania.
This research was carried out in a dense tropical forest region with the objective of improving the biomass estimates by a combination of ALOS-2 SAR, Landsat 8 optical, and field plots data. Using forest inventory based biomass data, the performance of different parameters from the two sensors was evaluated.
A methodology was selected so as to provide a consistent and robust approach to using GIS for data capture, interpretation, storage and analysis. This included the capturing of new coastal and terrestrial data along the Red Sea coastline in the timescale of the project and at an appropriate scale to carry out the site selection study.
La tercera edición de la WRB incorpora, en el nuevo capítulo 2, elementos que permiten generar nombres taxonómicos mucho más informativos que llevan a deducir con facilidad la génesis y funciones de los suelos. Por otro lado, esta nueva versión de la WRB facilita la elaboración de leyendas de mapas a varias escalas para uso multifinalitario.
Cities and Urban Areas play a crucial role as engines of development as well as centers of connectivity, creativity, innovation, and as service hubs for the surrounding areas. Kenya has experienced unprecedented urban growth. At independence the urban population was about 8%. This had grown to be about 40% by 2015.
This study focuses on land use in the tsunami inundation area caused by the Great East Japan Earthquake, particularly land use history in the tsunami-affected area. Hanagama District, Yamamoto City, Miyagi prefecture, was selected as the study area. Land use were examined using aerial photographs taken in 1975, 2010 and 2013.
