“…The perceptions in this study coincide with the scientific data reported by the Indian Meteorological Department ("Indian Meteorological Department") and other literature suggesting an overall increasing trend in summer temperatures in Jharkhand during the last 20 years (Tirkey et al, 2018). The rainfall trend in Jharkhand also appears erratic in last 20 years with a 26-270 mm decrease in the northern region where Godda is located (Tirkey et al, 2018). Several anthropogenic elements like land use changes, deforestation and environmental degradation have been documented as possible factors contributing toward the patterns observed, especially in the state's northwestern districts like Godda (Riebsame et al, 1994;Zhou et al, 2004;Rawat and Kumar, 2015).…”

“…The quantitative surveys also revealed similar climatic factors like erratic rainfall patterns contributing toward diminished agricultural production. The literature indicates that increasing summer temperatures may have led to water scarcity in the region (Tirkey et al, 2018), and erratic rainfall has impacted agricultural yields, especially for paddy cultivation. According to Jharkhand Action plan on climate change (2014), high rainfall (untimely rain) in rice flowering stage has caused reduced rice yield (Lal, 2001).…”

Climate change poses severe threats to the social, cultural, and economic integrity of indigenous smallholder subsistence farmers, who are intricately linked with their natural ecosystems. Sauria Paharia, a vulnerable indigenous community of Jharkhand, India, are smallholder farmers facing food and nutrition insecurity and have limited resources to cope with climate change. Eighteen villages of Godda district of Jharkhand inhabited by Sauria Paharia community were randomly selected to conduct a mixed methods study. In 11 out of 18 study villages, we conducted focus group discussions (FGDs) to examine the perception of this indigenous community regarding climate change and its impact on agroforestry and dietary diversity. In all 18 villages, household and agricultural surveys were conducted to derive quantitative estimates of household food consumption patterns and agroforestry diversity, which were triangulated with the qualitative data collected through the FGDs. The FGD data revealed that the community attributed local climatic variability in the form of low and erratic rainfall with long dry spells, to reduced crop productivity, diversity and food availability from forests and waterbodies. Declining agroforestry-produce and diversity were reported to cause reduced household income and shifts from subsistence agricultural economy to migratory unskilled wage laboring leading to household food insecurity. These perceptions were supported by quantitative estimates of habitual food consumption patterns which revealed a predominance of cereals over other food items and low agroforestry diversity (Food Accessed Diversity Index of 0.21 ± 0.15). The adaptation strategies to cope with climate variability included use of climate-resilient indigenous crop varieties for farming, seed conservation and access to indigenous forest foods and weeds for consumption during adverse situations and lean periods. There were mixed views on cultivation of hybrid crops as an adaptation strategy which could impact the sustained utilization of indigenous food systems. Promoting sustainable adaptation strategies, with adequate knowledge and technology, have the potential to improve farm resilience, income, household food security and dietary diversity in this population.

“…The district of Chatra is a part of North Chotanagpur plateau. The northwestern region of Jharkhand like Palamu and Garhwa in particular, has been suffering from an extended dry spell which has led to a number of severe impacts in the region [2]. This area is full of several mountains and valley most part of district area fall of forest and stone, Chatra district is well endowed with forest in an area of 226499/sqm which is about 60% out of total geographical area.…”

The FLD experiment was conducted in 20 replication (Farmers field) in National Innovation on Climate Resilient Agriculture (NICRA) village Mardanpur in Arra Panchat of Chatra block in Chatra district of Jharkhand on three consecutive year 2014-15, 2015-16 and 2016-17. The FLD experiment was conducted in randomized block design with 2000 m2 plot size for each technological option. The two technology options are as follows TO-I: (Farmers Practice) Burning of plant leaf in forest area and use as cooking material and transplanting ginger in the month of May without mulching with N100P60K60. TO-II: Mulching of ginger field by plant leaf (5 q/ha) with N75P40K45. The rationale behind selection of technology option (TO-II) was disseminate scientific recommendations i.e. mulching of ginger field to demonstrated famers convincing the benefit of mulching in the place of burning leaf in forest area. The data on soil chemical analysis before and after mulching, yield and economic was recorded for better interpretation matrix ranking was done for each of intervened treatments on the basis of farmers criteria matrix ranking was accomplished through participatory rural appraisal. Farmer’s reaction was measure in five point rating scale. The overall score reflecting the degree of favorable, unfavorable and neutral to the related technology intervention (Negative = 2.5, Natural = 2.3 – 3.5 and positive above = 3.5). Result indicated that on an average ginger yield was 144.83 q/ha in farmers practice where as in technology option (TO-II), it was 187.7 q/ha respectively. Return per rupee spent was also found more in TO-II i.e. 4.99 as compare to farmer practice i.e. 3.88.

“…Various district of Jharkhand state is prone to drought and parts of Ranchi, Lohardaga, Gumla and Khunti districts were affected by climate change. These areas shows variation in maximum temperature, minimum temperature, rainfall and solar radiation in rabi and kharif season which result poor vegetation health of crops in these areas (Pandey et al 2012;Tirkey et al 2018;Chaudhary & Pandey 2019). The plateau type hard rocky terrain in these regions experience high runoff inducing soil moisture stress and concomitant drought.…”

“…The Koel river basin lies in plateau terrain where rainfall induced runoff is a major problem, which has led to a water scarcity in the region. Long-term climatic variability showed that rising temperature and reducing rainfall over the Koel river basin and as a consequence, there is a reduction in crop productivity owing to increasing drought events (Tirkey et al 2018).…”

Global warming influencing regional climate is playing a significant role in triggering the recurrent drought. The current study demonstrates a PCA (Principal Component Analysis) driven watershed prioritization in a part of Koel river basin by runoff computation during monsoon season along with assessment of Vegetation Health Index (VHI) derived from MODIS satellite data during the period from 2000 to 2017. Koel river catchment area of 7,261 sq km was divided into 82 sub-watersheds based on drainage networks derived from Survey of India (SOI) topographical map on scale 1: 50,000. High resolution satellite image of Sentinel-2 was used to prepare land use land cover map. Soil conservation service curve number method (SCS CN) was used to estimate runoff. Result obtained from runoff estimation of 82 sub watersheds shows high runoff (50 to 60% of rainfall) with 290,000 m3 total runoff volume in the upper and middle parts of the catchment dominated by agricultural/fallow and barren lands whereas low runoff was estimated (20 to 30%) with 29,467 m3 in the lower catchments where a large area is covered with forests. The value of satellite based VHI ranges between 23 to 53 with major parts of the area exhibiting values less than 30 reflecting poor vegetation health. Most of the sub-watersheds in parts of Ranchi, Lohardaga, Gumla and Khunti districts experienced high total runoff with poor vegetation health index reflecting more proneness to drought. Watershed prioritization was done based on correlation among four parameters viz., rainfall, drought zones, direct runoff and total runoff through PCA. Strong correlation between total runoff volume and drought areas was used for watershed prioritization which indicated 42 sub-watersheds (4,703 sq km) in the upper catchment required high prioritization. The outcomes of study would help proper planning of water resources and soil moisture management to overcome the recurrent drought conditions at watershed level.
