Abstract: The extension of the Asian Elephant’s Elephas maximus range in the northern Western Ghats (Sahyadri) was observed since 2002.  This colonization was marked by elephant crop raiding events in the newly colonized Sindhudurg District, where the local community had no experience of living with elephants.  The present study was conducted to understand the spatiotemporal patterns of crop depredation (raiding) and to prioritize areas to inform future interventions on managing this ecological phenomenon turned conflict.  Data on crop raiding between 2002 and 2015 was obtained from compensation records with the state forest department, and mapped at village scale.  Subsequently, we used three indices of crop raiding, viz., Crop Raiding Frequency (CRF), Relative Crop Raiding Intensity (RCRI), and Crop Raiding Vulnerability Index (CRVI).  Results show a gradual northern movement of elephants and of the crop raiding zone over the period of 2002–2015.  The rankings provided by CRVI, identified villages in a narrow strip of foothills of the Sahyadri mountains as severely vulnerable.  With sufficient long term data, CRVI would be a highly useful index for prioritization of villages for resolving human-elephant negative interactions; and other cases of human-wildlife interactions too.

Introduction

 

Negative interactions between humans and elephants are a consistently rising conservation and social problem across the range of elephants in Asia (Gubbi et al. 2014).  Given the ancient records of crop depredation (raiding) and other negative interactions, they are part of the cultural and social memories in the areas of human-elephant interface (Sukumar 1991).  Thus, these issues need to be approached by integrating the dimensions of ecology, social perception, and economics in order to resolve the conflict and mitigate the losses (Choudhury 2004; Sukumar et al. 2012; Patil & Patil 2018, 2019). 

The Asian Elephant Elephas maximus (hereafter ‘elephant’) is listed as “Endangered” on the IUCN Red List of Threatened Species (IUCN 2017).  It is distributed in the Indian subcontinent and southeastern Asia, where it is found in a small fraction of its historical range (Sukumar 2006).  A significant elephant population is present in the Western Ghats of peninsular India, where the northern limit of population was recorded up to the Uttara Kannada landscape (Choudhary et al. 2008; Baskaran 2013; Mehta & Kulkarni 2013).  The historical range of elephants in the Western Ghats is suggested to have extended farther north than the present range.  Numerous petroglyphs dating from the Neolithic age and depicting elephants, have been recently discovered in Ratnagiri and Sindhudurg districts of Maharashtra (https://www.thehindu.com/news/national/other-states/the-petroglyphs-of-ratnagiri/article25265399.ece), which is north of the known limit of elephant distribution in the Western Ghats.  Yet, the traditional elephant range did not include the states of Maharashtra, Goa, and northern parts of Karnataka state (Mehta & Kulkarni 2013).  At the outset of the 21st century, however, an elephant herd from the Haliyal-Dandeli Forest Division moved north and colonized Belgaum Forest Division in 2001 (Baskaran 2013; Mehta & Kulkarni 2013).  Since November 2002, elephants from Dandeli Wildlife Sanctuary were reported further north in the forest-plantation mosaic of Sindhudurg and Kolhapur districts of Maharashtra.  Here, the elephants had not been reported for at least 100 years before this colonization, thus limiting the societal memory of living with elephants.  As a consequence, the colonization was marked by many villagers reporting elephant raiding cases to the state forest department.  Since then, the influx has been continuous and elephants have become resident in this area. 

Crop raiding by elephants can influence the perception of local communities towards wildlife and allied services, and result in conflict situations (Balasubramanian et al. 1995).  There have been demands from local people to remove elephants from their villages and send them back to the ‘wild’.  Following public pressure, a few elephants were captured by the forest department in 2009 from Dodamarg Taluka of Sindhudurg.  They were released to their native habitat in northern Karnataka; however, understanding the habitat fragmentation in this landscape, elephants are likely to disperse more seeking forage, refuge, and water, and thus increasing interface with people (Bhaskaran et al. 2010).  Hence, it is essential to understand the spatiotemporal pattern of elephant movement and the raiding hotspots in the landscape.  Although the problem of crop raiding by elephants has been widespread in Sindhudurg District, the intensity and distribution of the problem was not uniform throughout.  Several factors including elephant behaviour, topography, and physiography of landscape, human landuse and interventions determine these patterns.  Forest department officers mentioned the number of elephants in the study area varied from 4 to 11 individuals over the study period.

Within this context, the present study was conducted to understand distinct spatiotemporal patterns in crop raiding, and to prioritize areas for future interventions so that the recurring problem can be successfully handled. 

 

 

Material and methods

 

Study area

The Sindhudurg District (15°37’–16°40’ N and 73°19’–74°18’E) is the southern coastal district in western Maharashtra, with a geographical area of 5,207km2.  The study area has a tropical climate and the year could be divided into three seasons consisting of summer (February to May), monsoon (June to September), and winter (October to January).  The terrain is hilly with coastal lowlands.  Around 52% of Sindhudurg is covered by moist deciduous and semi-evergreen forests (FSI 2015), out of which 89% is under the ownership of private landholders and communities (Patil et al. 2016).  Figure 1 depicts the location of Sindhudurg District, its talukas and villages, with reference to the forest cover and terrain.  The villages with elephant crop raiding cases are numbered and the names of these 225 villages are provided in the supplementary information (Appendix 1).  The Sindhudurg District is subdivided into eight talukas (administrative divisions), viz., Vaibhavvadi, Devgad, Kankavli, Malwan, Kudal, Vengurla, Sawantwadi, and Dodamarg, which in total hold 748 villages.  Approximately, 87% of the human population in Sindhudurg is engaged in agriculture with an average landholding of one hectare (www.censusindia.gov.in).  Major crops include rice, millet, and pulses.  Rice is planted twice a year: June to September and November to February.  The second phase is locally specific based on availability of either natural water or if irrigation is available.  A large proportion of land is cultivated as orchards such as mango, cashew, coconut, areca nut, banana, and pineapple.  Spices like nutmeg and black pepper are cultivated within coconut orchards.  Home gardens are a widely adopted traditional agroforestry system.  Thus, the vegetation cover in the area is an intense mosaic of orchards, farms, and natural as well as degraded forest patches.

 

Data collection

Data on crop raiding between 2002 and 2015 was obtained from compensation records in the range offices of the state Forest Department.  We defined a ‘case’ as an entry in the forest department register of compensation, which was used for reporting elephant caused damage by local people.  We defined a ‘raid’ as a specific instance of damage of a particular crop.  A single ‘case’, where more than one type of crop was damaged, would represent a number of ‘raids’.

For each crop raiding case, the name of the crop owner, forest range of jurisdiction, taluka, village, date of crop raiding, crop damage & magnitude, and the compensation paid were noted.  Data of area under cultivation for coconut, areca palm, banana, and rice was obtained from the State Agriculture Department.  It must be noted, however, that the data for two years (2002 and 2015) were incomplete.  Reports on crop raiding appeared towards the end of the year 2002 and therefore data was not available for earlier months.  Similarly, for the year 2015, the cases recorded only till August matched with the study time-frame.

 

Data analysis

Hoare (1999) suggested use of Raid Frequency Index (RFI), which, in the present case, can be calculated as elephant raids per village per month; however, being an absolute index, RFI cannot be compared across studies, nor does it provide a standardized value between certain limits.  Therefore, three different indices of crop raiding were used to assess spatial patterns of crop raiding by villages, viz., Crop Raiding Frequency (CRF), Relative Crop Raiding Intensity (RCRI), and Crop Raiding Vulnerability Index (CRVI).

CRF is the total raiding instances in a village over the entire study period.

Where,

N  number of raiding cases in a year

i  study period in years

RCRI is a plain measure of crop raiding intensity incorporating the ratio of number of raiding instances to months of raiding occurrence.

Where,

j  number of nominate months in which raiding occurred

CRVI is based on standardized Levin’s measure, where the number of cases in a particular month is weighed (multiplied) by the number of years in which raiding occurred in that month.  Here, for the purpose of this index, only the count of months out of 12 nominate months was taken and total number of months of raiding in entire study period was not considered.

Spatial data for district, taluka, and village boundaries was obtained from the Survey of India for the year 2011.  The basic unit in this database was village, whereas that in the compensation database was a compensation claim registered in the name of a person belonging to a particular village.  The compensation data was reduced to village level by calculating the above mentioned indices.  These indices were joined as attributes to the spatial database to prepare maps based on indices at the scale of villages.  These rank correlations were estimated for the first 10 villages based on CRF.

Further, the compensation data was sorted by years in the study period and similarly maps of raiding frequency were prepared for each year to show the progression of the crop raiding by elephants in the study area.  Apart from the crop availability, elephant movement is known to be influenced by the availability of water and habitat cover (Venkataraman 2005).  High resolution (~30 m) satellite images depicting forest cover (FSI, 2015) and water (Pekel et al. 2016) were used to understand the habitat cover and water availability.  The locations of affected farms and the interviewed farm owners were mapped using ArcGIS 10.6.1 (Redlands, CA).

 

 

Results

 

From the compensation records of the forest department, information was available for 9,148 cases.  The conflict situation under study was spread over an area of ~4,300km2 of Sindhudurg District.  The database revealed 244 villages (33% of the total villages) affected by crop-raiding elephants (Table 1).  The top 20 worst affected villages by elephant crop raiding in various talukas during 2002 to 2015 are given in Table 2.

There was a gradual increase in raiding frequency from 2002 to 2008.  Then, there was a sudden dip during 2009–10 after which it increased again (Figure 2).  Again in 2015 the raiding frequency dipped.  Since elephants colonized this area, the highest number of cases was recorded in the year 2007 (Figure 2).  Further, four elephants in Kudal were captured by the forest department in 2009, and three were captured in 2015 and hence the frequency of crop raiding reduced during those years. 

CRF and RCRI of all affected villages are shown in Figure 3 and 4, respectively.  The distribution of villages in various RCRI classes is shown in Figure 5. Tulsuli K. Narur, Naneli, Wados, Karivane, Nivaje, Sonurli, and Dingne villages had highest CRF and RCRI values.  CRVI was calculated for all villages (Figure 6) and the distribution of villages in various CRVI classes is shown in Figure 7.  The highest CRVI was observed in the villages of Hirlok, Tulsuli K. Narur, Wados, Amberi, Pawashi, Tulsuli, and Kariwade (Table 2)

CRF, RCRI and CRVI provide useful information for identifying villages with severe problem of crop raiding.  In the present case study, however, the prioritization of villages based on CRF and RCRI was found to be highly correlated for the three most affected talukas, viz., Kudal, Sawantwadi, and Dodamarg (Table 3).

 

 

Discussion

 

Patil & Patil (2019) published trends and patterns of elephant crop raiding in the same study area during the period 2002 to 2015.  They mentioned coconut palms (44%), paddy (22%), banana (20%), and areca palms (8%) were the most damaged crops by elephants.  Paddy was found to be the attractant for elephants.  They also found that raiding frequency was maximum during winter season which coincides with the maturity and harvesting period of paddy in the Sindhudurg.  Patil & Patil (2017) published farmers’ perception survey towards elephant crop raiding in Sindhudurg.  Here, they presented the details of crop protection measures and their effectiveness, ongoing ex-gratia schemes by the forest department in the study area with possible coexistence approach.  The present study is the extension of these two studies.

Excluding the incomplete data-years of 2002 and 2015, the trend in annual raiding frequency seems to have followed the number of elephants active in those particular years.  The number of elephants active in a particular year, in turn, was dependent on the influx of elephants and efforts of the state forest department to capture and/or translocate elephants back to their southern population.  Various guestimates on the number of elephants ranging 4–11 individuals was provided by the forest department and secondary sources (Sarma & Easa 2006; Mehta & Kulkarni 2013).

Gradual extension of the conflict zone over the period from southern to northern parts of Sindhudurg was observed during 2002–2015.  It was also observed that crop raiding was severe in the talukas nestled in the Sahyadri Mountain ranges, while coastal talukas had relatively less cases.  Similarly, because elephants extended their range from south to north, the northernmost talukas were either unaffected or less affected during the study period.

Figure 2 shows the gradual extension of conflict zone (area wise) in the study area over the period of 2002–2015.  It could be clearly seen that during 2002 to 2008, the raiding events by elephants were spatially widespread and could be potentially exploratory in nature.  In 2009, four elephants were captured (out of which two died) for translocating them back to the closest population in Karnataka.  It is presumed by villagers and forest department personnel that these translocated elephants soon returned along with two other elephants.  In this second stint from 2010 to 2015, the map clearly depicts increased crop-raiding events from the Kudal range.  Towards 2014–15, the elephants started to further explore northwards.

Indices calculated in the present study are based on detailed ex-gratia records proved by the forest department.  CRF indicates that villages on the steeper ranges were not affected much compared to the foothills; however, the absolute CRFs or their proportion per village do not provide opportunity for comparing the intensity of crop raiding across studies.  Therefore, an attempt was made to calculate two further indices of vulnerability of villages to crop raiding based on historical data.

The high crop raiding villages identified using CRF and RCRI do not reveal the actual vulnerable villages because many of these villages were affected for a relatively brief duration with higher intensity.  Here we may conclude that villages with higher CRF or RCRI may not be vulnerable as elephants might have explored these villages for available resources intensively during earlier years but, finding them unsuitable, might have altogether stopped approaching.

CRVI, as previously stated, is the number of cases in a particular month weighed by the number of years in which raiding occurred in that month.  It provides a different ranking of the villages thus showing low correlation with both earlier indices (Table 3).  The rankings provided by CRVI appear to provide more meaningful geographical or ecological information.  A comparative look at Figures 3, 4, and 6 reveals that CRVI identifies villages in a narrow strip of foothills of Sahyadri mountains as severely vulnerable.  Gross factors determining elephants’ use of a certain area are food, cover and water (Fairet 2012).  It appears that the best possible combination of these three factors was available to the elephants in the area identified by CRVI.  Subsequently, CRVI could become a useful index to identify villages highly vulnerable to crop raiding by elephants.  The prioritization of villages for resolving human-elephant negative interaction can be based on CRVI, rather than CRF or RCRI, when sufficient long-term data on elephant crop raiding is available.  CRVI can also be compared across studies if crop-raiding instances are tabulated by villages or any small geopolitical units.  Use of these geopolitical units will facilitate implementation of various schemes for alleviating crop raiding problem.
