    GIS based approach for atmospheric carbon absorption strategies through forests development in Indian situations
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Yadav, Surendra Kumar
    Geographical information system (GIS) play important role in forest management. An effective strategy for enhancement of atmospheric carbon absorption productivity is through forests development in degraded forest areas and waste lands. Forestry sector has significant emissions removal capability which can further be enhanced by operationalizing major afforestation and reforestation initiatives like National Mission for a Green India besides continued strengthening of the present protection regime of forests. Secondary data was collected and analyzed. Different types of waste lands require different strategies for their development into forest areas; but few waste lands like rocky regions, glacier regions etc cannot be developed into forest areas. Atmospheric carbon management is major problem before world community in present circumstances to control environmental pollution. Various forest ecosystems play significant role in carbon absorption. The diffusional net absorption rate of anthropogenic carbon to the biosphere is some unknown function of the atmospheric partial pressure of carbon dioxide. Estimations reveal that the average carbon absorption of the forests was around 1,240 grams (1.240 Kg) of carbon per square meter of canopy area. To stabilize atmospheric CO2, role of forestry depends on harvesting and disturbance rates, expectations of future forest productivity, and the ability to deploy technology and forest practices to increase the retention of sequestered CO2. There is a considerable self-damping effect that will moderate the future increase of the atmospheric carbon dioxide concentration. Capacity of the ocean to absorb carbon dioxide is limited; but atmospheric carbon absorption potentiality of India forests can be increased tremendously through reforestation, afforestation and development of degraded forest areas and waste lands. About 60 % of Indian waste lands can be developed to increase forest cover with reasonable efforts. When National Mission for a Green India as part of the National Action Plan on Climate Change (NAPCC) becomes operational, the capability of the forestry sector to contribute in GHG removal will further enhance. Furthermore, afforestation and reforestation of 6 million hectares of degraded forest land covered under the National Mission with participation of Joint Forest Management Committees (JFMCs) would be able to add another 18 mt of carbon = 66 mt of CO2eq (approximately) by 2020. In Indian situations and similarly in other regions on the globe, atmospheric carbon absorption productivity may be enhanced through forests development with reasonable efforts. Similar efforts anywhere on the globe may be useful to develop waste lands and degraded forest areas to enhance overall atmospheric carbon absorption productivity.

    Spatial technology in forest ecosystem development and management
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Yadav, Surendra Kumar
    Spatial technology i.e. Remote Sensing (RS) & Geographical Information system (GIS) play important role in ecosystem management. Remote sensing or satellite data due to synoptic coverage, repetitive data gathering capabilities, spatial information, economically cheaper & sustainable technology, real time data collection & computer compatibility, coupled with GIS are extremely useful in monitoring, assessment, evaluation & management of total environment. Remote sensing data or satellite data are extremely useful for monitoring, assessment & evaluation, planning and feedback mechanism and management of all components of environment (various ecosystems, natural resources etc.). Satellites provide both spatial and temporal information needed to understand changes in resources for their distribution, qualitative & quantitative assessment. Multi-spectral satellite data having specific utilities for vegetation mapping, classification, quantification, spatial analysis, temporal change detection, detection of diseased & stressed vegetation etc in addition to pigmentation, physiological structure, and architectural organization and water contents are attributes, which are responsible for vegetation reflectance in multi-spectral data. Remote sensing/ Satellite images help environmentalist to observe (land cover, boundaries, threats, damage, topography etc.), monitor (change in forest cover, range condition, land use etc.), classify (into vegetation and land use categories, habitats etc.), measure (areas, distances, height/elevation etc.), detect (fires, resource use violations) etc. for natural resources management. Because reflected electromagnetic radiations are different for different substance or object therefore digital number (DN) value is different for different objects, this DN value is useful for object identification & image interpretation which is done through involvement of shape, size, tone, shadow, pattern, texture, size (location), association and resolution of satellite imagery/ data. Spatial information/ data & distribution pattern of each Parameter/ component of Natural Resources (NRs) & ecosystem is obtained through interpretation of satellite/ Remote sensing data with limited ground truth/ checks (field based). GIS can handle huge data sets (spatial & non-spatial data). All the data (spatial & non-spatial) are integrated in GIS and analysis & modeling in GIS using satellite and other data is done for monitoring, planning & management plans and finally for decision making & sustainable development and therefore in biodiversity, ecosystem and environment management.
