Importance of remote sensing in environmental management Rating:
Remote sensing is the use of technology to acquire information about an object or phenomenon without making physical contact with it. In the field of environmental management, remote sensing plays a vital role in understanding and monitoring the earth's natural systems and resources.
One of the primary uses of remote sensing in environmental management is the monitoring of land use and land cover change. This involves using satellite imagery to track changes in the type and extent of land cover, such as forests, grasslands, and urban areas. This information is important for understanding the impacts of human activities on the environment, as well as for planning and decision-making related to land use.
Remote sensing is also used to monitor the health and condition of natural resources, such as forests, grasslands, and wetlands. By using satellite imagery to track changes in the density and biomass of vegetation, scientists can assess the impact of environmental stresses such as drought, fires, and pests. This information is critical for understanding the impacts of climate change on natural systems and for developing strategies to mitigate these impacts.
In addition to monitoring natural systems, remote sensing is also used to monitor and manage human-made environments, such as urban areas and agricultural lands. For example, satellite imagery can be used to track the growth and expansion of cities, as well as to monitor the use and management of agricultural lands. This information is important for understanding the impacts of human activities on the environment and for developing strategies to mitigate these impacts.
Remote sensing is also used to monitor and manage natural disasters and emergencies. By using satellite imagery to track the extent and severity of events such as hurricanes, earthquakes, and oil spills, scientists can provide timely and accurate information to help emergency responders and decision-makers respond to these events effectively.
In conclusion, remote sensing is an essential tool in the field of environmental management. It allows us to monitor and understand the earth's natural systems and resources, as well as the impacts of human activities on these systems. By using remote sensing to gather accurate and timely information, we can make informed decisions and take effective action to protect and preserve our environment for future generations.
Remote Sensing: A Tool for Environmental Management
Another form of satellite data that is frequently used in environmental management, is Landsat imagery. Spectral signatures and spectral mixture modeling as a tool for targeting laterite and bauxite ore deposits, Koraput, Orissa. Why is remote sensing important for conservation? An extensive body of literature within numerous natural science disciplines documents the development of, or potential for, satellite sensor data analysis techniques to identify environmental attributes and monitor physical and biological processes relevant to global change research. Efforts targeted at sustaining infrastructural development in Nigeria are deficient in context and formalisation. This can help with water-use decisions on the farm or in the community.
You can find out more about sensing applications and their use with other technologies here. Urban growth analysis using spatial and temporal data. In response to the situation remote sensing can be expected to be used increasingly to collect urgently needed data, especially as related to monitoring changes in forest cover, assessing landus and frorest land degradation, evaluationg the productivity of the land and providing information not only for forest inventory but also for direct inputs to forest management and strategic planning. Special consideration was given to scientific manuscripts that covered, but were not limited to, the development of geospatial techniques and remote sensing applications for detecting, quantifying, and monitoring freshwater water resources, identifying potential threats to water resources and agriculture, as well as other themes related to water resources and environmental management at various spatial scales. Remote sensing data for regional wetland mapping in the United States: Trends and future prospects. Articles that benefited from recent advances in satellite technologies, as well as the easy availability and accessibility to large volumes of archival spatial datasets and data analytic techniques for water resources and environmental management, were prioritized.
Role of Remote Sensing and GIS in Environmental Impact Assessment (EIA)
Remote sensing and the disaster management cycle. Identifying a volcanic hazard zone can be difficult, especially if one has no idea of the land in question and has no access to the history of a particular place. Advances in Remotely Sensed Data and Techniques for Wetland Mapping and Monitoring. The environment needs to be monitored for an effective and improved understanding of how everything runs. Remote sensing of biotic effects: Zebra mussels Dreissena polymorpha influence on water clarity in Saginaw Bay, Lake Huron.
Satellite data also makes it possible to determine temperature, wave characteristics, chlorophyll content, the concentration of yellow matter and suspended sediment, potential fishing zone, etc. Assess the accuracy of classified data;Use the results of a remote sensing analysis to evaluate soil survey data; and. The study also discussed in detail the importance of cull factor for estimating merchantable yield. Remote Sensing of the Environment: An Earth Resource Perspective. For effective management of forest resources the various basic requirements and priorities are essentially of three tier system i. The application of Geographic Information System in this sector is that it helps in determining the changes in land use and cover in different areas.
However, one of the main challenges is to have access to the most up-to-date and accurate geospatial data and interpretations. Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance from the targeted area. Such an information with the available knowledge of minimum girth area for extraction it is possible to calculate the yield and also to compute the annual coupes based on equiproductive areas. Shoreline change analysis and its application to prediction: A remote sensing and statistics based approach. Variability of aerosol parameters over Kanpur, Northern India. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area. However, the extended use of this information for effective utilisation for the management purpose at the state level could be better achieved by supplementing the data each reserve forest boundaries thereby enlisting the districts having ore degraded areas.

The decline in potential water sources may also exacerbate droughts and increase water supply challenges in an already water-stressed catchment. All this would be impossible without technologies, among which remote sensing takes a key position. Remote sensing from space, the air, or on the ground can provide maps of many important environmental parameters-information that is not available in any other way. Orbiting the Earth every 89. It evaluates the spatial position and assembles layers of informative data into images. Groundwater prospective zones in Basaltic terrain using remote sensing.
Remote Sensing Environmental Applications and Uses
Traditionally there are two separate methods of deriving soil moisture data from space. Innovation enables us to build a more sustainable future, produce green and renewable energy, monitor endangered species, use natural resources more efficiently, and more. Remote sensors fall into two classifications; passive and active. The application of Geographic Information System in this sector helps in the provision of various options for wetland mapping and design projects, which are used in the conservation of wetlands. The data allows identifying potential fires and other risks. The policy formulation and strategic planning is at the central level. Farmers in developed countries do the retention of soil nutrients, and they use soil mapping to arrive at an informed decision.
How remote sensing is used in environmental management?
The organization of data feasibility adopting micro scale to macro scale may be a viable approach rather than adopting top to bottom approach stasr6ting with coarse resolution data which may fail to reveal any meaningful outputs required at the working level.
