Drought stress is one of the most important environmental stress that affects plant growth and development. Strawberry plants are very sensitive to drought stress due to its herbaceous nature and shallow root system. Depending upon the nature, intensity, duration and cultivars, the effect of this stress augments losses in yield and quality of the fruits. This optimization of yield loss and quality is due to the response of the plant to the stress with the changes in morphological, physiological, biochemical and molecular attributes. Drought stress results in the change of leaf anatomy, leaf area, transpiration rate, photosynthesis, stomata closure, relative water content (RWC), shoot length, root length etc. ROS such as H2O2 production occurs as a result of drought causing oxidative damage to the plant cells. Strawberry plant on the other hand have a mechanism to detoxify these ROS with the production of both the enzymatic and non-enzymatic antioxidants such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), gluthathione, ascorbic acid, tocopherols, carotenoids etc. [ABSTRACT FROM AUTHOR]

The shifting cultivation in Arunachal Pradesh is dynamic in nature and is known as 'Jhum'. Upland rice is the main crop grown in mixture with maize, foxtail, finger millet, beans, cassava, yam, banana, sweet potato, ginger, chillies, vegetables, etc. in such system. The single crop of rice is preferred in the second year and this continues for 2-3 years and then it is left for fertility build up through regeneration of vegetation. The period is known as 'fallow period'. But this leads to considerable soil erosion due to heavy intense rainfall instead of increasing its fertility. The fallow period has been reduced from 10-20 years to 5-7 years. Fortunately the mindset of the jhumias of East Siang district of Arunachal Pradesh, India has been changed. They cultivate citrus, bamboo and tache (wallichia) trees in these fallow lands, which not only prevent the land from soil erosion, but also give income even from a short fallow period. This is a little shift from the traditional practice towards a sustainable practice adopted by the jhumias. The paper presents the current scenario of settled cultivation from traditional jhum in reference to East Siang district of Arunachal Pradesh. [ABSTRACT FROM AUTHOR]
