Large cardamom is a major cash crop for the Mengio circle of district Papum pare, Arunachal Pradesh. Large Cardamom farming has been popular amongst all the inhabitants of the region within a span of six years. The farming activities are not very labour intensive, hence most of the activities carried out by the woman. However, due to the ignorance of the farmers, nonformalised marketing network, less coordination amongst the farmers, they are not able to harness the proper value of the large cardamom. Ultimately, the farmers sell these products to the intermediary at a very nominal price. Though they cultivate with very less chemical usage, still they are not able to receive the proper price for organic farming. Informal marketing strategies, improper storing, and packing facility create constraints for the farmers of this region. The peoples of this region have stopped livestock farming, due to the problem of fencing. The project would also try to mitigate the issues related to livestock farming, and multi-layer cultivation of Aloe Vera, Cinnamon, Black Pepper, Citronella, etc. through proper measures. The proposed project would give livelihood to the woman farmers through the elimination of the intermediary with the help of cooperative type of the organisation to market their product in different regions of the country. The project would also train the farmers to become the seller of the large cardamom in the market place with time-to-time help from the expert panel. The project would offer the farming community of the nearby region as one of the model for implementing in the nearby region. The profitability can boost up to consider the sustainable growth of this indigenous northeast people while not compromising the environmental issues. In order to save time and money, the large cardamom farmers used to cut down the trees for the large cardamom farming (Annexure figure-2). Therefore, apart from the livelihood of the farmers of this region, the project will also emphasis on deforestation, and soil erosion caused due to the large cardamom cultivation. Which can stop dangers of landslides caused due to soil erosion during the rainy season. Usage of woods for drying of large cardamom has also been a cause of creating air pollution; the project would also formulate the mechanised drying facility to overcome the same. A hybrid heat pump assisted solar dryer would be designed for drying of large cardamom. Three important parameters that affect the system performance of heat pump assisted solar dryer are solar radiation, compressor speed and the total load placed in the drying chamber. The other processing factors on which the design of a solar dryer depends are temperature of air, relative humidity of air, moisture content of the product, amount of product to be dried, time required for drying and availability of auxiliary energy. In this process, the solar collector will act as the evaporator of the heat pump system. Solar assisted heat pump systems will consist of i)Solar collector, ii) Heat exchanger as condenser, iii) Thermostatic expansion valve, and iv) Compressor. The organic farming can encourage eco-tourism through site visit. The reporting of the project would be on the Triple Bottom Line (TBL) considering economic, social, and environmental contexts of the region.
