“…Even a relatively modest warming of 1.5-2 °C in SA can severely impact the availability and stability of water resources due to increased monsoon variability and glacial meltwater, thereby threatening the future agricultural productions (Vinke et al 2017). With its impact on agricultural production and natural resources, climate change will bring greater fluctuation in crop production, food supplies, and market prices and will aggravate the situation of food insecurity and poverty in South Asian countries, which adversely affects the livelihoods of millions of people in the region (Schmidhuber and Tubiello 2007;Bandara and Cai 2014;Shankar et al 2015;Wang et al 2017;Aryal et al 2019b). It is projected that food price changes between 2000 and 2050 are 2.5 times higher for major food crops (e.g., rice, wheat, maize, and soybean) and 1.5 times for livestock products (i.e., beef, pork, lamb, and poultry) with climate change (Nelson et al 2009).…”

Agriculture in South Asia is vulnerable to climate change. Therefore, adaptation measures are required to sustain agricultural productivity, to reduce vulnerability, and to enhance the resilience of the agricultural system to climate change. There are many adaptation practices in the production systems that have been proposed and tested for minimizing the effects of climate change. Some socioeconomic and political setup contributes to adaptation, while others may inhibit it. This paper presents a systematic review of the impacts of climate change on crop production and also the major options in the agricultural sector that are available for adaptation to climate change. One of the key conclusions is that agricultural practices that help climate change adaptation in agriculture are available, while the institutional setup to implement and disseminate those technical solutions is yet to be strengthened. Thus, it is important to examine how to bring the required institutional change, generate fund to invest on these changes, and design dynamic policies for long-term climate change adaptation in agriculture rather than a mere focus on agricultural technology. This is one of the areas where South Asian climate policies require reconsidering to avoid possible maladaptation in the long run.

“…The impacts of climate change on agriculture and agricultural livelihoods have been identified as one of the primary barriers to sustainable development. Various consequences of climate change on agriculture include decreased crop output, altered water availability, soil erosion, an increase in pests and diseases, and-most significantly-affecting the socioeconomic stability of farming communities [1]. Changes in the climate influence agriculture around the world.…”

Climate change is viewed as the main problem of agriculture development in India. High dependence on agriculture and allied sectors makes the Indian state of Bihar vulnerable to climate change. Farmers' perceptions of climate change and their preferences for adaptation strategies must be understood in order to improve policies for addressing the issues that climate brings to farmers. Therefore, the main aim of the present study was to understand farmer’s perception of awareness of the climate change and their perception towards coping mechanism for changing climate. A total of 240 respondents were selected using purposive sampling in the % villages of Kishanganj district from March to May 2023. A descriptive research design was used in the study. Data was collected through face to face interview method using a semi structured interview schedule and analyzed using suitable statistical tools and techniques. It was found that the majority of farmers had a medium level of socio-economic characteristics. From the study result it was found that farmers were aware of about the climate change. Farmers agreed that the peak time of seasons has changed and there is a change in the onset of monsoon. Farmers exhibited resilience to changing climate through various local adaptation practices such as Switch to timely weather forecasting information, Climate-resilient practices, etc. The findings will help to refine and enrich the knowledge among the stakeholders to provide an effective framework for decisions and policy making.

“…In most Asian countries, rice is the staple food. Rice yields are decreasing with increased cellular respiration and carbon metabolism due to increasing global average temperature [ 1 , 2 , 3 ]. Thus, effectively increasing rice yields under adversity is a prominent challenge requiring urgent attention.…”

Rice is one of the three major crops in the world and is the major crop in Asia. Climate change and water resource shortages may result in decreases in rice yields and possible food shortage crises. In this study, water-saving farming management was tested, and IOT field water level monitoring was used to regulate water inflow automatically. Plant height (PH) is an important phenotype to be used to determine difference in rice growth periods and yields using water-saving irrigation. An unmanned aerial vehicle (UAV) with an RGB camera captured sequential images of rice fields to estimate rice PH compared with PH measured on site for estimating rice growth stages. The test results, with two crop harvests in 2019, revealed that with adequate image calibration, the correlation coefficient between UAV-PH and field-PH was higher than 0.98, indicating that UAV images can accurately determine rice PH in the field and rice growth phase. The study demonstrated that water-saving farming is effective, decreasing water usage for the first and second crops of 2019 by 53.5% and 21.7%, respectively, without influencing the growth period and final yield. Coupled with an automated irrigation system, rice farming can be adaptive to water shortage situations.
