Long-term monthly rainfall observations (1986-2014) were analysed for 12 rain-gauge stations installed at variable altitudes of Mizoram. Our objective was to assess the temporal change in the standardized precipitation index (SPI) values at different timescales using Mann-Kendall trend tests. Significant reductions in post-monsoon and winter rainfall were recorded for most of the sites. Increasing dryness during the winter months may intensify the acute water shortage in Mizoram. Our results emphasize the altitudinal insensitivity of mean monthly rainfall trend and prove the urgent need for adopting suitable water management practices to cope with the water scarcity problem to increase the resiliency of rabi agriculture in Mizoram in near future.Keywords

The north eastern region (NER) of India receives bountiful rains (>2000 mm) annually. However, there is extreme water scarcity during post- and premonsoon season (November-March). In such a situation, roof water harvesting (RWH) holds promise for multiple livelihood opportunities. RWH unit with polyfilm lined water collection tank of 37 m3 storage capacity (i.e. 5.5 x 4.5 x 1.5 m3) was demonstrated at 11 farmers fields mostly on hill tops in the Ri-Bhoi district (Meghalaya). The average demonstration area was 500 m2/farmer in the vicinity of homesteads (kitchen gardens). Volume of water harvested in a collection tank was about 53 m3 including about 16 m3 harvested during dry season due to seasonal replenishment. The cost of water harvesting was estimated at about Rs 144 and Rs 119/m3 considering lifespan of five and ten years respectively. Farmers used harvested water for diversified activities such as raising crops [maize, broccoli, French bean, laipatta (Brassica juncea), tomato, etc.] and livestock (pig or poultry) in addition to domestic use. The farmers without RWH could use land only during rainy season for crop cultivation. On an average, the net income from each RWH based model (500 m2 demonstration area) was Rs 14,910 for crop + piggery and Rs 11,410 for crop + poultry farming which was 261 and 176% higher, respectively than the normal farmers' practice. Similarly, employment and water use efficiency enhanced by 221 and 586%; and 168 and 218% under crop + piggery and crop + poultry based farming respectively.Keywords

The study was undertaken to identify various traditional tools and implements used for agricultural operations by the farmers of Sikkim. A total 28 tools were documented and tools like Halo-Juwa, Daatey, Phewri, Kaata/Haatey Kaata, Kodalo, Kodali, Hansia, Khurmi, Kachia, Khukuri, Bamfok, Elaichi Churi, Bancharo, Ramba/Jhyampal, Jaato, Okhlee and Mushlee, Dhikki, Ankhe Doko/Sipringey Doko, Thunche, Namlo, Chaalni, Nanglo, Daalo/Pathee, Bhakari and, Dhekutti were found in every household of the rural farmers. The study also revealed that most of the farmers of Sikkim have small and fragmented land holdings and continue to use indigenous tools and implements as it is considered to be cheaper, economical, and easily available in the local villagesReferences

The North Eastern Hill region offers scope for cultivation of a wide variety of horticultural crops such as fruits, vegetables, flowers, tuber crops, spices and plantation crops because of its diversities in topography, altitude and climatic conditions. The fruits grown in this region range from tropical and sub-tropical fruits like banana, papaya, pineapple, jack fruit and citrus to temperate fruits like apple, pear, peach, plum, strawberry and even certain nut fruits. The region has rich diversity of different vegetable crops and both indigenous tropical vegetables and temperate vegetables are grown to a considerable extent. Among the flowering plants special mention may be made about the orchids, where about 600 species are reported to occur in the region alone. The other commercial flowers of the region are marigold, tuberose, gladiolus, gerbera and chrysanthemum. Recently rose, gerbera, anthurium and liliums etc. are introduced in the region. Tuber and rhizomatous crops like tapioca (cassava), sweet potato, Dioscorea, colocasia, ginger and turmeric grow abundantly in the region, while plantation crops like tea, coconut, arecanut, cashewnut have considerable impact on the economy of the tropical and sub-tropical parts. The region is the big reservoir of medicinal and aromatic plants. Besides, many other indigenous fruits and vegetables like prunus berry, tree bean, tree tomato, edible bamboo etc. are found in the hilly terrains that can be explored for processing and value addition.- Climate Resilient Agriculture in Manipur:Status and Strategies for Sustainable Development

Manipur in India is endowed with rich biodiversity and abundant natural resources. Despite inaccessibility, marginality and heterogeneity, the state has made good progress in agriculture and allied sectors. About 80% of the state population depends on agriculture for livelihood. However, agriculture sector in Manipur is facing the consequences of climate change. Climate change is a reality and an increasing trend in temperature, precipitation and emission of greenhouse gases has been observed in Manipur. The state is also projected to experience more of extreme rainfall and reduction in crop yields. As subsistence level farming is coupled with prevalent shifting cultivation, the small and marginal farmers will be most affected due to climate change. Hence, there is an urgent need for devising climate proof plan and climate ready policy for climate compatible agricultural development in Manipur. Location-specific climate smart technology baskets need to be devised or introduced and should be demonstrated through participatory approach, for ensuring a climate resilient production system, and a climate resilient ecosystem. The interactions between the system’s adaptation strategies and the mitigation potential should also be given due importance in the action plan for combating climate change. This article deals with the present status of agriculture and allied sector and various technological and policy options for climate resilient agriculture in the hill and mountain ecosystems of Manipur.Keywords

We studied the variable dynamic response of different soil properties under the exposure of three elevated temperature treatments on six land-use systems. After one month of incubation, the associated changes were measured in terms of soil fertility, carbon, microbial biomass and soil enzymes. Our results confirmed the significant increase (P < 0.05) in soil available nitrogen content (by 1.85–49.32 %) with the subsequent rise in incubation temperature for soils collected from orchards and agriculture land uses. We observed a steady decrease in total organic carbon (TOC) levels with increase in incubation temperature varying between 4.1% and 31.4% (P < 0.05) across different soil types and land-use systems, resulting in a significant rising trend for microbial biomass carbon and labile carbon : TOC ratio up to 3°C elevation from maximum temperature. Among the soil enzymes, dehydrogenase, fluorescein diacetate hydrolase and β-glucosidase activity increased significantly with increase in incubation temperature from the ambient temperature, while acid phosphomonoesterase and arylsulphatase activity decreased. Our current research findings will provide new insights regarding temperature control on soil C dynamics and nutrient availability in terms of modified soil enzyme activity that will be useful to model the dynamics of soil organic matter and associated nutrient availability in acid soils.Keywords
