IDENTIFICATION AND MAPPING OF DEGRADED LANDS USING REMOTE SENSING AND THEIR MITIGATION REGIMES: A CASE STUDY OF WEST HARYANA (INDIA)

摘要

The degraded lands require a strategic management after the threats indicated to our livelihood and food security cited by various literatures. The agricultural efficiency is antagonistically influenced by degradation of various types. This study culminates different management practices applicable to different degradation types for establishing a proper channel of supervision with reference to West Haryana. An area of 181630.36 hectares was found degraded in the study area with different categories of degradation (waterlogged, water erosion, eolian erosion, salinization and anthropogenic) for the year 2015-16. Resourcesat 2 LISS Ⅲ imagery was employed to identify and map problematic lands indicating eolian erosion as the most prominent category of degradation. The categories were identified and mapped analogous to their spectral reflectance and visual interpretation. The partially stabilized dunes availed the highest place in extent of area dispersal occupying 98143.16 ha while the anthropogenic degradation (mining and brick kilns) extend to 382 ha. The influence of these categories of degradation on environment and their managing strategy has been focused in this paper. The fanner's choice of agriculture practice is an aggregate of various influential factors such as knowledge, labour, crop choice, fertilizers availability, irrigation, soil health and much more. The evaluation of problematic soils with poor soil health is the concern of present study additive of the management strategies to be adopted. Establishment of horizontal linkages between agro-forestry interventions, watershed development, integrated farming systems and degraded lands for management regimes has been brought up to enhance productivity for sustaining future perspectives. The designed approach is to reduce and reverse degradation by various practical interventions in different degradation types. The effect of degraded lands can be mitigated by stipulated action of suggested management policies reviewed in the study.
