Summary: This study used long-term satellite data and climate factors to analyze the start of growing season (SOS) of natural rubber in tropical areas. The study found that preseason sunshine duration had the greatest impact on SOS, and SOS had a significant delay with the increase of latitude.

Summary: Effective grazing management in Australia's semi-arid rangelands requires monitoring of landscape conditions, understanding of environmental factors, and management of soil health. Rotational spelling and moderate stocking rates have been found to enhance soil health and contribute to the long-term integrity and profitability of cattle production in pastures.

Summary: This study evaluates the SEAS5 seasonal forecasting system produced by ECMWF for its applicability in the Central American Dry Corridor (CADC). The results show that SEAS5 predictions have better skill during the mid to late wet season, but worse skill during the early wet season. The forecast skill varies spatially, with higher skill in the southeast CADC.

Summary: This study analyzes agricultural droughts in the red and laterite zones during the monsoon seasons using MODIS and SAR data. The results show that MODIS-derived indices and SAR data can be used to identify severe drought years that lead to crop failure. Additionally, the study finds that satellite-derived evapotranspiration index and soil moisture index are better correlated with evapotranspiration and rainfall meteorological indices.

Summary: The study focuses on the survival performance of FPV system under real weather conditions without blocking evaporation. Stress and strain tests were conducted on pontoons, with the elasticity module, yield limit, and tensile strength measured as 0.42 GPA, 11.5 mPA, and 19 mPA, respectively.

Summary: The study calculates the electrical energy produced by photovoltaic panels on rooftops in Istanbul using building data and verifies the results with a mobile measurement system. Results show that the potential of rooftop electricity production in Istanbul has the ability to meet 67% of the total electricity consumption in 2019.

Summary: This study based on three different floating photovoltaic systems installed on Buyukcekmece Lake in Istanbul reveals that warpage of floating photovoltaic elements due to harsh wave action is a serious problem, and existing designs might not be suitable. Comparing with previous designs, the new 30 kWp floating photovoltaic designs proved to be more robust and sustainable under severe wind and wave conditions. Therefore, floating photovoltaic systems need to be flexible as a whole, while individual units must remain stable.

Summary: Floating Photovoltaic (FPV) systems installed on Buyukcekmece Lake in Istanbul help reduce evaporation loss and generate electricity, despite the severe weather conditions. A fully flexible FPV system proved to be more resilient compared to a semi-flexible frame prototype. However, both FPVs and Terrestrial Photovoltaic (TPV) systems showed similar electricity generation capabilities.

Summary: One of the most impressive applications of renewable energy is the use of floating photovoltaic (FPV) power plants. However, determining the best locations for installing these facilities is a significant challenge. Currently, there is a lack of a standardized methodology for evaluating optimal deployment locations for FPV systems worldwide. This study analyzed three essential natural constraints, including solar irradiance, wind speed, and wave height, over a reservoir in southwestern Turkey to identify suitable sites for FPV installation. The results provide a new methodology, called FPV Convenient Reservoir Surface (FPV-CRS), which includes essential guidelines for micrositing FPV facilities.

Summary: This study investigates the impact of a mid-latitude cyclone on planned floating photovoltaic facilities in Antalya, Turkey. Using the WRF model, sensitivity analysis is conducted to determine the best configuration for the model outputs in different regions. The study also calculates regional wave characteristics using a modified Shore Protection Manual method.
