Impact of different types of meteorological data inputs on predicted hydrological and erosive responses to projected land use changes

Abstract: Hydrological responses to land use/land cover (LULC) changes are complex in nature and tend to have an impact on the hydrological cycle, affecting the livelihood of the inhabitants. Rainfall–runoff models, such as the Soil and Water Assessment Tool, were used in the past to unravel the interactions between the impacts of climate and land use changes. However, the sensitivity of the model outcome, regarding the hydrological and erosive response to climatic data derived with different methods, has not been fully understood. We carried out a hydrological simulation using (a) Climate Forecast System Reanalysis data set, which synthesises outputs of global climate models along with gauged weather information and has a global coverage, and (b) purely weather station-based gridded climate data provided by Indian Meteorological Department. A possible LULC scenario for the year 2020 was created using the combined Cellular Automata–Markov model. Application of both climate data sets resulted in a modest increase in the predicted streamflow and sediment yield as a response to the probable development scenario in 2020. However, the marked variations emerged in the location and monthly pattern of significant changes in the surface runoff and sediment yield in response to the likely LULC scenario for 2020 vis-a-vis 2010.

Adaptability of Crop Insurance Schemes in Tamil Nadu

Abstract: The experiences gained in the execution of various crop insurance products in India have been described along with the ways to redesign the strategies for effective implementation of such crop insurance products. The study is based on the data collected from 90 farmers covered under National Agricultural Insurance Scheme (NAIS) in three selected districts in Tamil Nadu, viz. Nagappattinam, Vellore and Madurai and 30 farmers covered under Varsha Bima, a weather-based insurance product in the Nagapattinam district. The major problems in the implementation of NAIS, as indicated by respondents, are: poor awareness about the scheme, delay in settlement of claims, complex procedure, high premium rate and wide variation between yields of actual and crop-cutting experiment farms. In the case of Varsha Bima scheme implemented in the Nagapattinam district, the major problems faced by the farmers are: non – availability of the benefit since the implementation of the scheme, poor awareness about the details of weather insurance schemes, high premium rate and wide variation in rainfall between the farm and the Reference Weather Station. The study has offered several suggestions, based on farmers’ perceptions, to refine the existing crop insurance schemes in India.

A Survey on Weather Monitoring System in Agriculture Zone using Zigbee

Abstract: In agriculture zone it will be very difficult to check and monitor the weather parameter through wires and analog devices during some weather hazards. To overcome this problem here the wireless sensors are used to check and monitor the weather parameters. Monitoring the weather parameters in agriculture zone plays an important role in farming production processes. In this system, a wireless sensor network based on Zigbee/IEEE802.15.4 standard is utilized as a weather station network sending weather information or guideline to the farmers to plan their farm. The weather parameters which are measured by the system are temperature, humidity in the soil, wind speed and wind direction. The system takes advantage of wireless sensor networks which can send signals over far distances by using a mesh topology; this transfers the data and also consumes low power. Therefore, this system can be installed in locations that are difficult to hardwire or have no access to electricity.

Design and Construction of a Low Cost Digital Weather Station

Abstract: This work is focused on the design and construction of a low cost weather station which makes weather related data available for different purposes such as agriculture, aviation weather forecasting, etc. The design is made up of an outdoor module which measures four weather elements (temperature, atmospheric pressure, relative humidity and wind speed) through their respective sensors. This module transmits the sampled data wirelessly through radio frequency (RF) to an indoor module which receives the data and automatically logs the data to a database. A MATLAB® based graphical user interface (GUI) was also incorporated to view the logged data and perform some setup operations on the system.

Solar photovoltaic power in the state of Kuwait

Abstract: Solar photovoltaic technology is considered to be one of the most promising types of renewable energy technologies in the State of Kuwait, and has garnered global attention in recent years due to the growing energy demand and concerns over climate change This paper provides an assessment of two elements regarding photovoltaic module functions: first, the local optimum tilt angle, and second, the annual power output of four photovoltaic modules of different types at the optimum tilt angle The System Advisor Model [SAM] is utilized to perform computer simulation and analysis of the functionality of each of the modules The data was collected hourly using solar radiation measurements at the Kuwait International Airport weather station (29°N, 47°E) Kuwait's average solar intake is about 9–11 hours per day with an average daily solar insolation that can reach more than 70 kWh/m2/day This potential solar energy technology can be applied for a capacity credit/factor in power generation, a potential economic returns, and environmental benefits for the country Special attention has been placed on the amount of useful power produced by the photovoltaic systems, on the technology's ability to handle the extreme weather conditions, particularly the high temperatures that occur in Kuwait, and on the effect of changing the tilt orientation on the systems' performance This study reveals the PV modules' best performance across the determined parameters in a hot and harsh climate The results can be generalized to similar climates and provide valuable technical data for the design conditions, installation and application of photovoltaic systems
