Community Conserved Areas in Northeast India and Their Role in Addressing Human-Wildlife Conflict
Integration of local communities in nature/wildlife conservation is increasing, and the emergence of “Community-Conserved Areas” or CCAs in recent times is a testimony to that. Keeping northeastern India as the regional focus, this chapter aims to understand the evolution, nature and types of CCAs in this region and analyze their role, with particular reference to local human-wildlife conflicts in and around CCAs. These CCAs, comprising different land-use elements, have resulted in a decentralized model for governance and empowerment for the communities, but their role in reducing the emerging threat of human-wildlife conflict is understudied. Human-wildlife conflict through crop and livestock damage negatively affected the villages surrounding the CCAs, and such damages produced significant friction among various conservation actors. With two cases of human-wildlife conflict around CCAs from Nagaland, a biodiverse state in northeast India, this chapter delves deeper into the governance of this critical issue
Reconstructing the geological and geomorphological history of Morella Crater, Mars
Ancient impact craters on Mars provide insights into the geological events and are time markers for studying global processes like colossal volcanism and fluvial activities. Among these craters, the 77 km diameter Morella Crater serves as a representative, capable of demonstrating diverse processes that acted on Martian terrain, and hence, the geological and geomorphological history of this crater is studied in detail. Despite its infilling, Morella hosts Ganges Cavus, a significant collapse structure, and Elaver Vallis, an outflow channel. We hypothesize the development of the crater through five stages, from its origin to its current denuded state, exhibiting diverse processes that determine the fate of Martian craters. Crater size-frequency distribution suggests a formation age of
Ga for the plateau hosting Morella Crater and
Ga for Morella Plains, the vast expansive plains within the crater. The occurrence of pyroxene and olivine in Morella Plains, identified through hyperspectral data, indicates impact-induced volcanism. The heat source associated with faulting and dike intrusion in the adjoining Ophir Catenae Structural Complex might have ruptured the confined cryosphere, resulting in the formation of Ganges Cavus and eventual filling of Morella with water, which subsequently breached to form Elaver Vallis at
Ga. Hydraulic modelling reveals a floodwater volume of 3.27 × 1012 m3 and an estimated peak discharge of 3 × 107 m s−1 associated with this event. Morella witnessed additional fluvial activity at
Ga that created the dark-toned channels. The extensive range of geological and geomorphological processes makes Morella Crater a promising location for future Mars missions
