Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Traditional therapeutic uses of animals and animal products among indigenous people of Idukki district, Kerala, India
    (Department of Wildlife Sciences, College of Forestry, Vellanikkara, 2021-12-31) Shijith S Nair.; KAU; M Shaji
    Humans have known about ethnobiological uses since ancient times and rely on fauna and flora for medicines, food, clothing, and other necessities of life. For their basic health-care needs, the world population is looking for an alternative medication generated from natural resources, and this natural alternative, which consists of various bioactive chemicals, may be more effective with less toxicity than manufactured pharmaceuticals. The Western Ghats are home to a diverse range of fauna and flora, with plant-based medicines accounting for the majority of natural medicines discovered thus far. Animal medicines, on the other hand, have a restricted number of references. Rural communities, who have acquired millennium old traditional wisdom from their predecessors and handed it down through generations, are crucial in disease management. Poverty and a scarcity of medical facilities are to blame, they rely mainly on traditional knowledge, hence This knowledge is only available in rural regions. Before it is depleted as a result of rising urbanisation, modernization, and industry, traditional plant and animal recipes must be recorded. It is critical to document particular human societies' plant and animal usage that are passed down through the generations in undiscovered areas. Furthermore, with the growing threat of microorganism resistance to existing allopathic medications, novel natural chemical combinations with synergistic or additive effects are desperately needed. As a result, the project was designed with the goals of 1) analysing and documenting indigenous people's ethnozoological knowledge in Kerala's Idukki area. 2) additionally, document the creation and use of medications derived from animals and animal products, and 3) quantitative indices are used to determine the highly desired ones. This might be the first investigation in the specific location to describe traditionally used medicinal fauna and its recipes. The findings of the study might help preserve traditional knowledge and identify new taxa as a potential source of adjunct to conventional medicine. 84 The outcomes of the reseaech followed imply that local populations in Idukki have a good understanding of how to make ethnomedicine out of faunal diversity based on what's available. This research preserves ethnobiological data while also laying the groundwork for pharmacological, phytochemical, and synergistic research. People employ animal products/parts either alone or in combination with other things to treat a variety of human diseases. The findings also reveal that ethnomedicine is an important part of the primary health care system in the research area, but that it is mostly centred on flora rather than fauna. The animal recipes offer new perspectives on drug research that, through synergistic mechanisms, may pave the way for the development of new and effective therapies. Traditional knowledge is rapidly fading; hence scholars are being encouraged to perform further study in this region so that it may be preserved and documented.

    Economic valuation of ecosystem services: A case study of kole wetlands, Ramsar site
    (Department of wildlife sciences, College of Forestry,Vellanikkara, 2021) Neha, Tamhankar; KAU; Nameer, P O
    Wetlands are one of the most productive ecosystems on the planet, equivalent to tropical evergreen forests, and they play an important role in ecological sustainability. The quality and extent of these wetlands are rapidly deteriorating. The purpose of our study, was to determine the services offered by the wetland as regarded by stakeholders and to quantify the economic value for various ecosystem services. It was held in one of most important wetland systems in Kerala, the Kole wetlands, which has been designated as a Ramsar site. The data used in this study was collected from both primary and secondary sources. Primary data respondents were chosen using a multistage random sampling method (200 samples), and data was collected using a personal interview method with a pretested organised schedule. The obtained data was analysed by using market value approach, travel cost method, replacement cost method, benefit transfer method, and contingent valuation method. The farmers involved in paddy farming, fishing activities, lotus farming, and those leasing land for duck rearing are the stakeholders relying on the Kole wetlands. Another key economic activity in the Kole wetlands is tourism, accounting additional income to the farmers. Flood storage, groundwater recharge, and carbon sequestration are some of the additional indirect benefits. The relevance of wetland ecosystem services was recognised by the respondents. Crop raiding by birds, pollution, floods, and poor wetland management are important issues that the farmers have facing at Kole wetlands. The Total Economic Value (TEV) of the system is composed of direct use value, indirect use value and non-use value. The level of income generated by wetland-related activities was used to calculate the direct use value of the wetland. Paddy cultivation worth Rs. 126 crores per year, highlighted as most important service provided by the Kole wetland. It has a direct usage value of Rs. 148 crores and the flood storage function of Rs. 187 crores, whereas the groundwater recharge function is worth Rs. 9.9 crores per annum. It has a non-use value of Rs. 7.3 crores. According to the findings, wetland ecosystem services have an estimated economic worth of Rs. 390 crores per year which highlights its enormous importance. The findings of the study can be used to construct a socially acceptable management strategy for the conservation of long-term viability of Kole wetland.

    Utilisation of the waterholes by wild animals in Wayanad wildlife sanctuary
    (Department of Wildlife Sciences, College of Forestry, Vellanikara, 2019) Sachinkrishna, M V; KAU; Nameer, P O
    Utilisation of natural and artificial waterholes in Wayanad Wildlife Sanctuary (WWS) was analysed in this research work. Vayals are the natural swampy areas while the waterholes are the artificial ponds made by the forest department. The study was done with two objectives such as mapping ofthe vayals and the artificial waterholes in the WWS and the usage of these structures by wild animals. We used GIS tools for mapping ofthe vayals as well as artificial waterholes in WWS. The animal visitation was studied using the camera traps installed in the selected vayals and artificial waterholes across the four ranges of WWS from September 2018 to May 2019. The observations were made in dry season and wet season. The geo-coordinated maps of 171 vayals and 168 artificial waterholes in Wayanad WWS were prepared. It is interesting to note that most of the artificial waterholes were made within the vayals. A total of 21 species of wild animals were found to be using the water sources in WWS. The animal visits to vayals/natural waterholes were greater than that of the artificial waterholes. However, the animal activity in these water sources in the dry season was greater than that of wet season. The herbivores preferred vayals more than waterholes, but the frequency of visit of other animals such as carnivores, primates, etc. were found to be more in waterholes. The most abundant animal in Wayanad wildlife Sanctuary was Spotted Deer and its frequency of visit was higher in vayals than artificial waterholes. The frequency of animal visit at waterholes made inside the vayal is found to be higher than that of waterholes dug outside the vayal. The temporal activity pattern of water source usage was also studied. Most ofthe vayals and waterholes were used mainly during morning and evening hours. The direct usage of artificial waterholes for drinking water was rarely observed. Most of the visits made by herbivores to the waterholes were for grazing around the waterbody. The randomness of usage of water sources were also studied using Run test. Asian Elephant, Barking Deer,Gaur, and Wild Boar show a non-random usage of natural waterholes in the wet season. In artificial waterholes, elephant shows a non-random usage in wet season and the Spotted Deer and Sambar Deer shows non-random usage in dry season. The design of waterhole is also found to be affecting the animal activity. The side walls of many waterholes were made steep in such a way that it cannot be accessible by small animals like Spotted Deer, Barking Deer, etc. The quality of water is another factor that influences the usage. Many waterholes were not capable of holding water in the extreme dry months. The vayals kept moist throughout the year and supported the animals with good fodder in the lean periods. Constructing waterholes inside the vayals causes degradation of the swampy habitat and lead to drying up of vayals. It also affects the hydrology of that landscape. So,the present study highlights the importance of vayals and its management in protecting that habitat. The construction of artificial waterholes should be done with proper scientific studies.

    Efficiency of mitigation measures against crop raiding wild animals in Wayanad Wildlife Sanctuary
    (Department of Wildlife Science, College of Forestry, Vellanikkara, 2019) Wahiba Irshad, Humam; Nameer, P O
    A field study was conducted to map and document the human-wildlife conflict (HWC) mitigation measures being followed in Wayanad Wildlife Sanctuary and to examine the effectiveness of the various intervention measures used in mitigating the human-wildlife conflict at WWS. The study was conducted from September 2018 to May 2019 in all the four ranges of Wayanad Wildlife Sanctuary viz., Muthanga, Sulthan Bathery, Kurichiyat and Tholpetty. The mitigation measures such as Solar Power Electric Fence, Elephant-proof Trench and Elephant-proof Wall were mapped using the software QGIS ver. 2.18. Sanctuary level and range-wise maps were prepared. Socio-economic survey of the local communities residing near the forest fnnges was also conducted for understanding the extent of human-wildlife conflict, conflict mitigation measures and their effectiveness, attitude and perception of the people towards the HWC mitigation measures etc. The Land Use Land Cover Change (LULCC) analysis was also carried out by using Geographical Information Systems (GIS) and remote sensing technology, both inside the Wayanad Wildlife Sanctuary and in a 5 km buffer area outside the sanctuary during 2005-2006 and 2014-2015. The solar power electric fence was established along with the elephant-proof trench. A total of 190.265 km of fence-trench combination that was taken at Wayanad was mapped. The combination of solar power electric fence and elephant-proof trench surveyed was more in Muthanga range (56.535 km), followed by Kurichiyat range (46.626 km), Sulthan Bathery range (46.052 km) and Tholpetty range (41.052 km). The elephant-proof wall erected at Wayanad Wildlife Sanctuary were less than 200 m and the total length of the elephant-proof wall that could be mapped was only 654.16 m. According to the socio-economic survey that is conducted at Wayanad Wildlife Sanctuary, 99.17 percent of the respondents were the victim of crop damage, 45.83 percent of the respondents suffered from livestock loss and 40.83 percent of the respondents experienced threat to human life. Human-wildlife conflict was more due to Asian Elephants (91.67%), followed by Spotted Deer (89.17%) and Wild Boar (87.50%). 75 percent of the respondents has experienced crop loss and property damage due to Bonnet Macaque. Threat to livestock loss due to tiger/leopard attack was faced by 32.50 percent of the respondents. 26.67 percent of the respondents opined on that the damage caused by the Malabar Giant Squirrel on coconuts. In Wayanad Wildlife Sanctuary, mostly, a combination of elephant proof trench and solar power electric fence were established. The trenches and the electric fences are poorly maintained and thus they are less effective. The barriers also suffer a high rate of failure as people deliberately break them for accessing the forests for various reasons. Elephant-proof walls cause major ecological challenges, as it completely fragments the habitat and even affect the ecology and behaviour of several non-target species of wild animals too. Moreover, it has also been found to be highly ineffective as in almost all the sites the Elephant-proof walls were broken by the elephants. Biological barriers were also found to be ineffective to mitigate the human-wildlife conflict. Despite of a huge implementation of the mitigation measures, the overall conflict incidents has increased substantially. Based on the Land Use Land Cover change analysis, it was foimd that there is an increase in the built-up area inside the Wayanad Wildlife Sanctuary, especially in Kidanganad area of Kurichiyat range over the 10 years. Increment in the built-up area is found to be more in the buffer area (213.26 ha). There is a significant increase in built-up area and cropping area within and on the fringes of the sanctuary. This change in land use has been done primarily by the conversion of the natural vayals in and around sanctuary. This change in the land use pattern and the increase in the agricultural land area could be one of the reasons for the increased human-wildlife conflict incidents in Wayanad Wildlife Sanctuary.

    Comparison of feeding Ecology of two endemic species of langurs, Himalayan Grey Langur (Semnopithecus ajax) and Tufted Grey Langur(Semnopithecus priam)
    (Department of Wildlife Sciences, College of Forestry, Vellanikkara,Thrissur, 2019) Aakib Hussain Paul; KAU; Nameer, P O
    A field study was conducted to study the feeding ecology of two endemic species of the langurs viz., the Himalayan grey langur (Semnopithecus ajax) and Tufted grey langur (Semnopithecus priam). The study was conducted from August 2018 to April 2019 in Dachigam National Park, Srinagar and Wayanad Wildlife Sanctuary, Kerala. The Himalayan grey langur showed typical preference towards a particular feeding item during different seasons. Although the Himalayan grey langur is folivorous yet consumes a variety of food items such as fruits, roots, flowers, buds, bark and twigs. The Himalayan grey langur spent a considerable amount of time in searching and feeding of insects to maintain the ionic balance. The overall maximum feeding was reported in case of Rosa webbiana (9.54 %), followed by Populas deltiodes (8.11 %), Salix alba (7.63 %), Hedera nepalensis (7.63 %) and Aseculas indica (6.9 %). Rosaceae family was most preferred followed by Salicaceae. The most preferred food item was leaves (27.18 %) followed by fruits (22.75 %) and seeds (10.49 %). Average height of feeding was reported to be 5.68 m, which was maximum, in case of Aseculas indica and Pinus wallichiana (11 m), followed by Ulmus villosa (9.8 m) and Ulmus wallichiana (9.7 m). The Tufted grey langur was reported to be feeding on 12 tree species belonging to seven different families. The maximum duration of feeding in case of Anogeissus latifolia and Samanea saman (18.87 %) followed Dalbergia lanceolaria and Gmelia tillifolia (9.43 %), Terminalia bellarica (7.55 %). The Tufted grey langur diet mainly comprised of leaves, twigs and fruits. The leaves comprised of 60.38 %, twigs 20.75 % and fruits 18.87 %. The average height of feeding was 8.8 m, which was maximum in case of Hydnocarpus pentandra (12 m) followed by T. bellarica (10.5 m). The Himalayan grey langur spent maximum time in feeding followed by resting and grooming. The Himalayan grey langur spent 41 % of the time budget activity on feeding, followed by moving (21 %), resting (16%) and grooming (15%). Vegetation studies using quadrant survey showed a total of 26 species belonging to 16 different families. The species such as P. wallichiana, P. jacquemontiana, Q. robur and M. alba as dominant. The IVI was computed to show quantitative relationship among vegetation and highlight the importance of trees. The IVI values show that most important family of trees is Panacea, Hamamelidaceae, Ulmeace, Fagaceae, Cannabeacae and Rosaceae. Although major population areas of S. ajax and S. priam are protected areas yet special efforts are required for conservation of these valuable species which have been categorized as ‘Endangered’ and Near threatened’ by IUCN.
