Assessing the Impact of Land Use Changes and Rangeland and Forest Degradation on Flooding Using Watershed Modeling System
Extensive flood damages all over the world necessitate its control and operation. Hydrologic impacts of land use change appear in many ways such as total runoff, and flood peak flow. This study was performed in 2014 and aimed to investigate the impacts of land use changes on the occurrence of floods in the catchment of Boostan dam in Golestan province, Iran. For this purpose, Watershed Modeling...
متن کاملOptions for monitoring and estimating historical carbon emissions from forest degradation in the context of REDD+
Measuring forest degradation and related forest carbon stock changes is more challenging than measuring deforestation since degradation implies changes in the structure of the forest and does not entail a change in land use, making it less easily detectable through remote sensing. Although we anticipate the use of the IPCC guidance under the United Framework Convention on Climate Change (UNFCCC...
متن کاملModeling the Degradation of Hyrcanian Forests Using Logestic Regression Method (Case Study: Shenrood Forests, Guilan)
Having accurate quantitative and qualitative information about the state of forest stands, is necessary for any basic management and planning, to reduce the effects of forest degradation. The current study aimed to model the destruction of Hyrcanian forests under the effects of density and volume (per hectare) variables, using logistic regression. In total, 252 plots of 1000 m2 area were measur...
متن کاملA review of methods to measure and monitor historical carbon emissions from forest degradation
Disturbances that lead to forest degradation have been estimated to affect roughly 100 million hectares (ha) of forest globally per year (FAO, 2006, in Nabuurs et al., 2007). With respect to mitigation of climate change, forest degradation refers to a loss of carbon stock within forests that remain forests (IPCC, 2003a; UNFCCC, 2008). Degradation, therefore, implies that measured forest variabl...
متن کاملMapping Tropical Rainforest Canopy Disturbances in 3D by COSMO-SkyMed Spotlight InSAR-Stereo Data to Detect Areas of Forest Degradation
Assessment of forest degradation has been emphasized as an important issue for emission calculations, but remote sensing based detecting of forest degradation is still in an early phase of development. The use of optical imagery for degradation assessment in the tropics is limited due to frequent cloud cover. Recent studies based on radar data often focus on classification approaches of 2D back...
متن کاملCase Studies on Measuring and Assessing Forest Degradation Global Mapping and Monitoring the Extent of Forest Alteration: the Intact Forest Landscapes Method
ii Sustainably managed forests have multiple environmental and socioeconomic functions which are important at the global, national and local scales, and they play a vital part in sustainable development. Reliable and up-to-date information on the state of forest resources-not only on area and area change, but also on such variables as growing stock, wood and non-wood products, carbon, protected...
