“…The energy dissipation in paddy fields is dominated by latent heat, which leads to high evapotranspiration and lower temperature, with only a small amount of energy dissipated into sensible heat. 17 The high VPDs in 2010 were caused by high rainfalls that led to high air humidity.…”

This article is discussing the impacts of land cover change from paddy field to barren land in small scale area (1,516.5 km 2 ), on the surrounding local climate components in central Java, Indonesia. Data of several climate components from 2000-2010 were collected from weather stations that located separately. The land covers were dominated with cropland and little forest on eastern site, and settlements (urban) on western site. This study confirmed that the decrease in 13.1% of paddy field and the increase in 12.4% of barren land had significantly resulted in low daily actual vapor pressure (ea) during dry months with low rainfalls. The eastern areas that were originally occupied by croplands and trees, responded to the decrease of paddy fields by the increasing of air temperatures. The air temperatures and their variations at urban areas located in the western part were not distinctly affected by the land cover change.

“…Irrigated farmland also has a similar cold island effect (Cook et al, ; Kueppers et al, ; Salazar et al, ; Thiery et al, ), with significant local temperature cooling between nonirrigated farmland and the irrigated farmland. As a special irrigated farmland and quite different from irrigated dryland, paddy fields can be regarded as a kind of constructed wetland with seasonal standing water (Liu et al, ; Piao et al, ; Saptomo et al, ). At the regional scale, quantitative studies concerning paddy field expansion to mitigate the warming effect of wetland reclamation are important for the time‐varying diversification of land use change consequences.…”

The warming or cooling effects on regional climate in response to early land use change may be strengthened, weakened, or eliminated by the same or opposite effect in the subsequent land use/management period. Taking the Sanjiang Plain in China as our study area, this paper analyzed the surface temperature change due to land use/land management changes from the mid‐1950s to 2015, based on the land surface temperature response model and the observation minus reanalysis (OMR) method using remote sensing data, meteorological observation data, and reanalysis data. Results revealed a magnitude of monthly mean land surface warming up to 1.31 °C due to the land use change from wetland to rain‐fed farmland and a cooling effect of −1.32 °C caused by the land management change from rain‐fed farmland to paddy fields during the growing season. The trends were confirmed using OMR method. Land surface temperature change based on remote sensing data was divided into radiative and nonradiative forcing. The nonradiative processes play a dominant role in regulating the local surface temperature. The monthly mean temperature differences in response to land use changes differ greatly during the growing season. The temperature difference was greater in May and June (spring) than in July and August (summer). Our study shows that the land use impact on regional climate could be switched dramatically, and it would be basically consistent with the impact of natural wetlands before reclamation in our study area right now, which provides important information for mitigating and adapting to global climate change at regional scale.

“…The earth's atmosphere is experiencing a warming process due to global warming [1,2,3], this gradual increase in temperature of our planet is due to the increased anthropogenic greenhouse effect, which is considered to be a focal factor considerably affecting hydrological cycle and on the effectiveness of agricultural production systems with increased extreme events of rainfall and temperature [3,4,5]. Precipitation is the important variable which affects the crop productivity in general and rain-fed crops in particular.…”

Changing Climate is one of the most significant ecological issue, with the implications for agricultural production, water resource, energy and some other aspects of human well-being. Analysis of changing climate is important to assess climate-induced changes through the analysis of variability of climatic parameters such as temperature, precipitation, runoff and groundwater to suggest feasible adaptation strategies. This paper aims the long-term variability of rainfall and temperature using gridded daily data obtained from India Meteorological Department with 0.25 0 resolution from 1901-2016 for precipitation and 1 0 resolution from 1969-2005 for temperature (re-gridded to IMD 0.25 0 gridded location) in Ghataprabha sub basin (K3) of Krishna basin. The analysis of variability and trend in precipitation and temperature carried out by using coefficient of variation (CV), rainfall and temperature anomaly and also Mann-Kendall (MK) test was used to detect the time series trend. Statistical analysis of variability and trend in annual, Indian Summer Monsoon (ISMR) rainfall and temperature observed that i) there is an intra and inter annual variability of precipitation in the sub basin ii) test results revealed that the annual and ISMR trend appears to be increased by 0.12 & 0.14, iii) the Mann-Kendal trend test also analysed for annual minimum, mean and maximum temperature over the K3 sub basin (1969-2005) shows increasing trend by 0.06, 0.21 and 0.40. This analysis revealed that, there is an increasing trend in annual rainfall and temperature observed over the study region.
