Storage Change

Inland water storage change is a fundamental part of the hydrologic cycle, which reflects the impact of climate change and anthropogenic activities on water resources. In this study, we used multisatellite data (from satellite altimetry, remote sensing, and the Gravity Recovery and Climate Experiment (GRACE)) to investigate water storage changes in the Aral Sea and its endorheic basin. The water storage depletion rate in the Aral Sea from calibrated hypsometric curves (CHCs) created by satellite altimetry and image data agrees with the GRACE-derived result using the Slepian space domain inverse method (SSDIM). Compared with the combined filtering method (CFM) and mascon solutions, the SSDIM was shown to be an effective method of reducing the GRACE leakage error and restoring the signal attenuation in the Aral Sea. Moreover, we used the WaterGAP global hydrology model (WGHM) to qualitatively analyze the variations in the water storage components. The results show that the groundwater in the Aral Sea affects the change in the interannual water storage, especially during the extreme dry and humid periods. However, from the long-term water storage trend, the decrease in the surface storage dominates the shrinking of the Aral Sea. In addition, more details of the water storage change pattern in the endorheic basin were revealed by the enhanced GRACE solution. Our findings accentuate the severe water storage states of the Aral Sea endorheic basin under the impact of climate change and human interventions.

Quantitatively assessing the characteristics of river streamflow variation and conducting research on attribution identification are the basis for formulating climate-change response strategies and rational use of water resources. Based on the daily streamflow data of the Zhuangtou Hydrological Station in 1970–2018, this paper analyzes the streamflow changes in the Beiluo River Basin and studies the impact of climate change and anthropogenic activities on the streamflow in this basin. A non-parametric Mann–Kendall test and Pettitt’s test were used to determine the trend and detect abrupt changes of streamflow and baseflow. The method based on precipitation and potential evapotranspiration, as well as the double-mass curve of precipitation–streamflow, was established to evaluate the impact of climate change and non-climate factors on annual streamflow. The results reveal a statistically significant downward trend (p = 0.01) in both annual streamflow and baseflow, with the abrupt point year in 1994 and 1988, respectively. When comparing to a modest declining trend in annual average precipitation, we see that the temperature showed a significant upward trend (p = 0.01), whose abrupt point year was 1996. Under the policy of returning farmland to forest, land-use analysis shows that the area of farmland had decreased by 222.4 km2, of which 31.4% was mainly converted into the forestland. By the end of 2015, the area of forestland had increased by 123.4 km2, which has largely caused streamflow decrease. For the method based on precipitation and potential evapotranspiration, climate change contributed 43.7% of the annual streamflow change, and human activities (mainly refers to LUCC) contributed 56.3%. For the DMC of precipitation–streamflow, the precipitation contributed 9.4%, and non-precipitation factors (mainly refers to human activities) contributed 90.6%, and human activities played a more vital part in driving streamflow reduction in different decades, with a contribution rate of more than 70%. This study is of great practical significance to the planning, management, development and utilization of water resources in basins.

AbstrakPerubahan iklim bukan lagi menjadi sebuah omong kosong, kenyataan bahwa bumi semakin panas dan ancaman atas dampak perubahan iklim telah menjadi nyata. Pergeseran musim mengakibatkan kegagalan dalam bercocok tanam, kenaikan permukaan air laut mengancam keberadaan negara-negara kepulauan kecil. Banjir dan kekeringan adalah sebagian kecil dari dampak perubahan iklim yang telah nyata dirasakan. Bumi semakin panas, para ahli dalam Laporan IPCC WG I AR 5 semakin yakin bahwa penyebab perubahan iklim adalah akibat aktivitas manusia. Pertanyaan yang kemudian muncul adalah siapa yang bertanggung jawab atas kerusakan dan kerugian yang diderita akibat dampak perubahan iklim? Di Indonesia, Gugatan Warga Negara menjadi salah satu bentuk litigasi yang menjadi alternatif penyelesaian dampak perubahan iklim yang dirasakan oleh masyarakat. Abstract Climate change is not longer became an issue, we are facing the fact that earth is getting warmer and the impact of climate change is become real. The season changed, and affected the crops failure. The raising sea level threatening the existence of small islands. Flood and drought are simply the several impact of climate change that has been perceived. Earth is getting warmer, the IPCC Fifth Assessment Report of Working Group I ensure the main cause of climate change is from anthropogenic activities. The question that arose later is who will be responsible for any damage of the climate change impact? Citizen Law Suit in Indonesia has become one of litigation form that can be an alternative solution of climate change impacts in civil society.

Sorghum Chafer

Four insect species were reported as new potential pests of date palm in recent years. They are sorghum chafer (Pachnoda interrupta), the rose chafer (Potosia opaca), the sericine chafer beetle (Maladera insanablis), and the South American palm borer (Pysandisia archon). The first three species belong to the order Coleoptera and the family Scarabaeidae, while the fourth species is a lepidopteran of the family Castniidae. The injury as well as the economic damage caused by the four species on date palm need to be quantified. Due to climate change and anthropogenic activities, the date palm pest complex is expected to change in the future. To the author's knowledge, this article provides the first report of sorghum chafer as a pest damaging date palm fruit.
