India has a vast geographic diversity and accordingly has diverse responses to changing climate. The more than expected variations in the temperature are causing alterations in the water cycle and stressing the regional water availability along with agriculture significantly. With the current climate change conditions with globally evident rising temperatures, India has to face the challenge of sustaining its rapid economic growth along with ensuring food security to its increasing mainly agriculture-dependent population. The purpose of this research was to investigate the spatiotemporal variations in maximum and minimum temperature in terms of monthly and annual trends in west-flowing river basin of Kutch, Saurashtra and Marwar (WFR-KSM basin).

The trend was calculated and assessed in ProUCL5.0.00 and ArcMap 10 software using 36-year Indian Meteorological Department (IMD) maximum and minimum temperature grid (1° × 1°) data from 1969 to 2004. The direction and magnitude of annual and monthly trends were calculated for every grid using Mann–Kendall (MK) test and Theil–Sen’s (TS) slope. The trends in annual, maximum and minimum temperature were spatially analyzed annually and for every month from January to December. The majority of the area exhibited increasing trend in minimum and maximum temperature annually and in all the months from January to December. In annual maximum temperature, all grids exhibited positive slope ranging from 0.01 to 0.03 degree Celsius per year. In annual minimum temperature, majority of the grids (81.25%) exhibited positive slope ranging from 0.01 to 0.04 degree Celsius per year and none of the grids exhibited negative slope. Monthwise trend in maximum and minimum temperature also indicated rising trend in majority of the grids, with few grids identified with declining trend mainly along the eastern border of the basin.

印度地域辽阔，对气候变化的反应也各不相同。温度超过预期的变化会导致水循环发生变化，并给农业以及整个地区的水资源供应带来巨大压力。在当前全球气候变化和全球气温明显升高的情况下，印度必须面对维持其快速经济增长以及确保其日益增长的主要依靠农业为生的人口的粮食安全的挑战。这项研究的目的是根据库奇，索拉什特拉和马尔瓦尔（WFR-KSM盆地）向西流动的流域，按月和年趋势研究最高和最低温度的时空变化。

使用ProUCL5.0.00和ArcMap 10软件对趋势进行了计算和评估，使用了36年印度气象局（IMD）1969年至2004年的最高和最低温度网格（1°×1°）数据。年度和月度的方向和大小使用Mann–Kendall（MK）检验和Theil–Sen（TS）斜率计算每个网格的趋势。从每年1月到12月的每个月，对空间的年度，最高和最低温度的趋势进行空间分析。大部分地区每年的最低和最高温度以及从一月到十二月的所有月份都呈现出上升趋势。在每年的最高温度下，所有网格每年的正斜率范围为0.01到0.03摄氏度。在年度最低温度下，大多数网格（81.25％）表现出从0.01到0的正斜率。每年04摄氏度，并且没有一个网格显示负斜率。最高和最低温度的逐月趋势也表明大多数网格都呈上升趋势，只有少数网格主要沿盆地东部边界呈下降趋势。
