摘要

Ecosystems are distinct biological entities characterized by a range of functions. The integrity of the ecosystem is vital for sustaining ecosystem goods and services to support people’s livelihood. Maintaining ecosystem integrity requires ecosystem approaches in managing natural resources considering dynamics due to natural variabilities and anthropogenic activities. Sustainable developmental planning focuses on the efficient and innovative use of regional resources, with an improved understanding of social and environmental interactions. The comprehensive knowledge of a region’s ecological sensitivity/fragility is quintessential for evolving conservation strategies. Ecosystems’ ecological sensitivity refers to ecosystem stability, persistence, resilience, and recovery properties to overcome environmental disasters, which are likely to affect natural landscapes’ character adversely. The ecologically sensitive regions are natural resources-rich zones (NRRZ) endowed with distinct biological elements with geological, physical, and chemical characteristics. Spatial integration of geo-climatic, ecological, environmental, and social variables helps delineate NRRZ for prudent management of natural resources through ecological and conservation planning as per the Biodiversity Act, 2002, Government of India. NRRZ delineation has been done at disaggregated levels (9 km x 9 km grids) considering ecological, bio-geo-climatic, social, and environmental aspects compiled from field and published literature, and prioritization of NRRZ (as NRRZ 1 to 4) has been done through aggregated weightage metric score (of chosen variables per grid). The novelty of the current study is the prioritization of NRRZ at disaggregated levels (grids of 5’ x 5’ or 9 km x 9 km, equivalent to a grid in 1:50000 topographic map of the Survey of India) and also the decentralized governance unit- Panchayat through the integration of diverse multi-dimensional bio-geo-climatic, environmental and social factors. The strength of NRRZ is the replicability for prudent management of natural resources and real-world conservation governance. 32% of the state’s geographical area was depicted as a high-resource region under NRRZ 1 and 2, which needs to be conserved with stringent regulations. Prioritizing regions as NRRZ by integrating spatial data (land cover) with location-based attribute information would strengthen regional decision-making.
