Landslides is one of the most dangerous geologic hazards that can occur in almost any country on the planet. Landslides kill and injure thousands of people each year around the world, as well as cause significant losses in a short period of time. To save many lives, effective technology must be developed in a timely manner. Sensor Networks is a vital role to monitor the environment. Several online and real-time intensive care studies on landslide recognition were conducted on soil dislocation caused by non-natural rainfall and earthquake. To build an advanced level early warning landslide monitoring system based on the “Internet of Things” using a wireless sensor network. This is a high-level project that can monitor the earth’s vibrations, temperature, humidity, and soil moisture. All of these sensors are linked to various IoT Nodes, which form the entire network. The number of nodes may be increased or reduced depending on the situation. A single Blynk-designed smart phone software is used to track all of the Landslide detection nodes. Data from sensors reveals that each parameter has the potential to be used in landslide monitoring.

Recent The cultivation of flora by way putting the root in liquid nutrient solution is referred to as Hydroponic. Agriculture is the backbone of the growing us of like India, agriculture is disturbed with the aid of number of issues like manures, pesticides, small and fragmented land holdings, chemical used for plant growth etc. Hydroponics can be a higher idea to unravel these difficulties and moreover with the aid of using hydroponics we can go organic. Hydroponics is the quickest developing zone of agriculture and it is the technique of creating vegetation life in liquid with delivered vitamins on the other hand besides soil. The whole manner can be finished in room terrace, balcony and additionally in closed environment. Since it can be extended vertically, it has a acquire that many numbers of plants can be planted in a limited space. The plant boom is monitored weekly as soon as for the yield purpose. Since the drift of the used and smooth water for the watering the plant is automatic, few integral parameters like water level indicator, pH sensor, Automatic water dropper and DC motor. These parameters are controlled by Arduino board. Hence the plant is grown by way of capability of Eco-friendly method.

Aims: The trans-Himalayan high-altitude cold desert regions of India is characterized by a rugged topography at an altitude ranging from 2550 to 7742 meters above sea level. It has a vast geographical area of 72976 km2 with very little cultivated area of about 13726 hectare. Hydroponic is a soilless cultivation technique which may produce fresh vegetable in areas where environmental stress (cold, heat, dessert etc.) and limited space or on non-arable land is a major constrains for agriculture production. Methodology: The experiment was conducted under open natural ventilated double layer polycarbonate green house in cold desert high altitude conditions of Leh, India. The hydroponic structures were designed for crop production (viz. leafy greens, vegetables, fruits etc) in deep water culture (DWC) and nutrient film technique (NFT) hydroponic techniques and compared them with conventional soil grown system. Nutrient solution for growing vegetables was prepared and standardized. Results: The result obtained has shown that crop yield was significantly higher in hydroponic system as compared to traditional system for all crops. The recorded increase in yield for various crops in hydroponic system compared to soil grown system were: arugula 221%, atriplex 248%, coriander 288%, fenugreek 208%, lettuce 293%, mint 237%, mustard 227%, spinach 294%, cucumber 533%, strawberry 280%, summer squash 229% and tomato 345% which were significantly higher. Hydroponics can be explored to grow vegetables round the year especially for leafy greens. The hydroponic systems may come out as a valuable asset to forward and remote area of trans-Himalayan region for growing fresh vegetables where cultivated land and availability of the water are the limiting factors for crop production.
