The economy of North-Eastern (NE) region of India predominantly depends on farming, where only 12% of geographical area is available for cultivation out of which more than 85% is rain fed. Climate change has become a major concern in agriculture today, as farmers in many regions are struggling to cope with changing temperatures and rainfall pattern. Moreover, extreme weather situations like droughts, floods, heat and cold waves pose serious threat to food security, especially for small and marginal farmers. This review paper discusses the climate change in North-Eastern India based on the available climatic data from various published sources. Most of the analysis was performed on time series meteorological data recorded at different locations across the states of North-Eastern India namely, Assam, Arunachal Pradesh, Sikkim, Nagaland, Meghalaya, Manipur, Mizoram and Tripura. The increase in mean annual maximum temperature varied from 0.1°C per decade in Imphal (Manipur) to about 1.4°C per decade in Jharnapani (Nagaland). The changes were significant for all the states, except Sikkim. This region is one of the highest rainfall receiving regions of the world, but during February-March it faces water scarcity. The rainfall is projected to increase in 57 districts out of 78 districts, with some districts expected to experience almost 25% more rainfall than usual. The North-Eastern region of India has experienced notable changes in the pattern of major climatic variables such as rainfall and temperature. Average temperatures are projected to increase in almost all the districts of the region while annual rainfall is also reported to increase in almost 3/4th of the districts. The climate-induced natural disasters like drought, flood and hailstorms are the major threats of climate change and the incidence of these natural disasters are increasing in the recent years over the region.

Perceived Change

Climate change has negatively impacted the underdeveloped and developing countries including Nepal due to low adaptive capacity and higher dependency in agriculture. Forests are important component of the lives and livelihoods of the community in Nepal, which can offer an important source of climate-resilient livelihood. It is crucial to know the fact that climate change was in the past, which will continue to change in the future. It is essential to understand how communities perceive and adapt to climate change. A study was carried out in Kirepani, Jagreni and Kalika Community Forest User Groups (CFUGs) in Lamjung District with an objective of assessing their perceptions on impacts of climate change. The survey was carried out in 62 households along with participatory appraisal to understand the perception of local people on climate change and its impacts. Focus group discussion was held in each CFUG. Climatic data of 29 years (1987–2015) acquired from Khudi, Kuncha and Gharedgunga metereological stations and analysed to supplement the results. Data were analysed using MS-Excel as major computer software and presented as table, trend lines and graphs. The study showed that the locals correctly perceived change in temperature, unpredictable occurrence of rainfall and increased incidence of change in crops phenology, an increase in drought. Based on the perceptions of the community forest users, climate change has affected the biodiversity and societal system differentially. Drought has higher impact to the people affecting their lives and livelihoods. They perceived that the increase in drought, floods, landslide have affected their lives and livelihoods. The results revealed that minimum temperature was increased at the rate of 0.01º C per year whereas the maximum temperature was increased by 0.056° C per year. From the rainfall data of Khudi meteorological station, it was found that annual rainfall was highly decreased at the rate of 25.8 mm per year, which alarms for more disaster such as drought and fire in the area. Our findings suggest that for the innovative climate change adaptation planning and policy it is crucial to incorporate and acknowledge the role of community forest in climate change adaptation.

Abstract High temperature and elevated CO2 under future climate change will influence the agricultural productivity worldwide. Burgeoning population along with climate change situation is going to threaten the food security of India. According to IPCC 5th assessment report (2014), global mean surface temperature and concentration of carbon dioxide (CO2) at the end of 21st century will increase by 4.8°C and 539 ppm respectively under Representative Concentration Pathway (RCP) 8.5 scenario. Considering the burning issue present study aims to find out the probable change in different climatic parameters under high greenhouse gas emission (RCP 8.5) scenario during 2021-2095 and their impact on wheat yield and water productivity over six locations (Jalpaiguri, Nadia, Murshidabad, Malda, Birbhum and South 24 Parganas) covering five major agro-climatic zones of West Bengal, a state of eastern India. Results showed that maximum temperature (Tmax) and minimum temperature (Tmin) will increase by 5.3oC and 5.9oC during the end of this century. The increase in annual rainfall will be maximum (22%) at Murshidabad. Wheat yield will increase by 3 to 28% across the study sites. The seasonal crop evapotranspiration value will decline by 1 to 21%. Both water- use efficiency (WUE) and transpiration -use efficiency (TUE) will increase at all the study sites.

Evaluation of effects of climate change on climate variable extremes is a key topic in civil and structural engineering, strongly affecting adaptation strategy for resilience. Appropriate procedures to assess the evolution over time of climatic actions are needed to deal with the inherent uncertainty of climate projections, also in view of providing more sound and robust predictions at the local scale. In this paper, an ad hoc weather generator is presented that is able to provide a quantification of climate model inherent uncertainties. Similar to other weather generators, the proposed algorithm allows the virtualization of the climatic data projection process, overcoming the usual limitations due to the restricted number of available climate model runs, requiring huge computational time. However, differently from other weather generation procedures, this new tool directly samples from the output of Regional Climate Models (RCMs), avoiding the introduction of additional hypotheses about the stochastic properties of the distributions of climate variables. Analyzing the ensemble of so-generated series, future changes of climatic actions can be assessed, and the associated uncertainties duly estimated, as a function of considered greenhouse gases emission scenarios. The efficiency of the proposed weather generator is discussed evaluating performance metrics and referring to a relevant case study: the evaluation of extremes of minimum and maximum temperature, precipitation, and ground snow load in a central Eastern region of Italy, which is part of the Mediterranean climatic zone. Starting from the model ensemble of six RCMs, factors of change uncertainty maps for the investigated region are derived concerning extreme daily temperatures, daily precipitation, and ground snow loads, underlying the potentialities of the proposed approach.

This article deals with the issue of North-Eastern India, its current social and economic problems in the context of long-term demonstrations of the ethnic separatism. The main aim of the research implies systematic analysis and identification of key factors and reasons perpetuating separatism in NER as well as resource search which determines Indian strategy in solving this problem. The first part of the article is devoted to separatism peculiarities in the region which remains withdrawn and underexplored in many respects. Apart from this, the author provides a quite detailed analysis of negative mentality of the certain part of NER population which justifiably reproaches New Delhi for “discrimination” and inability to solve many problems of the region. Then the author paid the detailed attention to these problems of NER modern society (ethnic, demographic, economic, transport, social etc.) as well as measures undertaken by the Indian government for its settlement.
