Groundwater, the hidden part of the hydrological cycle, is often overlooked in the freshwater discourse, partly because the damage and changes that human activities cause are not immediately visible. Increasingly across the world, groundwater resources are strained with serious consequences.

Groundwater Dependent Ecosystems

Groundwater dependent ecosystems (GDEs) are increasingly threatened worldwide, but the shallow groundwater resources that they are reliant upon are seldom monitored. In this study, we used satellite-based remote sensing to predict groundwater levels under groundwater dependent ecosystems across California, USA. Depth to groundwater was modelled for a 35-years period (1985–2019) within all groundwater dependent ecosystems across the state (n = 95,135). Our model was developed within Google Earth Engine using Landsat satellite imagery, climate data, and field-based groundwater data [n = 627 shallow (< 30 m) monitoring wells] as predictors in a Random Forest model. Our findings show that 1) 44% of groundwater dependent ecosystems have experienced a significant long-term (1985–2019) decline in groundwater levels compared to 28% with a significant increase; 2) groundwater level declines have intensified during the most recent two decades, with 39% of groundwater dependent ecosystems experiencing declines in the 2003–2019 period compared to 27% in the 1985–2002 period; and 3) groundwater declines are most prevalent within GDEs existing in areas of the state where sustainable groundwater management is absent. Our results indicate that declining shallow groundwater levels may be adversely impacting California’s groundwater dependent ecosystems. Particularly where groundwater levels have fallen beneath plant roots or streams thereby affecting key life processes, such as forest recruitment/succession, or hydrological processes, such as streamflow that affects aquatic habitat. In the absence of groundwater monitoring well data, our model and findings can be used to help state and local water agencies fill in data gaps of shallow groundwater conditions, evaluate potential effects on GDEs, and improve sustainable groundwater management policy in California.

Surface And Groundwater

Groundwater resources plays important role in agro-biodiversity and environmental conservation perspectives. Surface and groundwater have played a significant role in the agrarian economics in the developing economics particularly in India. At the same time, the tropical and sub-tropical India is the largest groundwater user in the world through unregulated construction and utilization of millions of private wells in the last five decades exploited groundwater availability and sustainable regeneration issues. Hence, in order to improve the surface and groundwater conservation, regeneration, management and protection for sustainable utilization of Groundwater requires a participatory and coordinated action. Nationwide, many national and regional Non Government Organisations (NGOs) are functioning in the line of effective surface and ground water management the community. The recent Geographical Information Systems (GIS) based technologies also supports for drought mitigation and climate change adaptation. This study highlights the important NGOs led sustainable Groundwater management practices under various local hydro geological settings and agro economic realities for up scaling the community driven sustainable Groundwater management.

There are various signs indicating that the Earth's natural environment is changing toward unfavorable direction for species, which is highly suspected to be connected with human activities. In the last century, people all over the world have realized the severity of environmental issues. In the long history, Chinese ancient had already development good rules and methods to reach balance between economic development and environment sustainability. This paper will discuss how environmental concepts forms and which methods could be applied in the future.

Historical Importance

The historical importance of the principles and ideals that influence human activities can be measured by their expansion, their impact and their duration.It is humanity's instinct for self-preservation that has made the International Red Cross and Red Crescent Movement what it is—a vital force that has for decades played a decisive part in enriching human values; after 125 years of life it has lost none of its attraction, its influence is widespread and its membership steadily growing. Unquestionably its influence extends throughout the world, even though its development is beset with difficulties.

Flood Characteristics

In recent times, several studies focused on the global warming that may affect the hydrological cycle due to intensification of temporal and spatial variations in precipitation. Such climatic change is likely to impact significantly upon freshwater resources availability. In India, demand for water has already increased manifold over the years due to urbanization, agriculture expansion, increasing population, rapid industrialization and economic development. Numerous scientific studies also report increases in the intensity, duration, and spatial extents of floods, higher atmospheric temperatures, warmer sea, changes in precipitation patterns, and changing groundwater levels. This work briefly discusses about the present scenario regarding impact of climate change on water resources in India. Due to the insufficient resolution of climate models and their generally crude representation of sub-grid scale and convective processes, little confidence can be placed in any definite predictions of such effects, although a tendency for more heavy rainfall events seems likely, and a modest increase in frequency in floods. Thus to analyses this effect, this work considers real problems about the changing flood characteristics pattern in two river regions, and the effect of spatial and temporal pattern in rainfall. In addition to these, the work also examines the trend of groundwater level fluctuations in few blocks of Ganga–Yamuna and Sutlej-Yamuna Link interfluves region. As a whole, it examines the potential for sustainable development of surface water and groundwater resources within the constraints imposed by climate change.
