Study region: The Upper Kharun Catchment (UKC) is one of the most important, economically sound and highly populated watersheds of Chhattisgarh state in India. The inhabitants strongly depend on monsoon and are severely prone to water stress.
Study focus: This research aims to assess the impact of climate change on water balance components.
New hydrological insights for the region: The station-level bias-corrected PRECIS (Providing REgional Climates for Impact Studies) projections generally show increasing trends for annual rainfall and temperature. Hydrological simulations, performed by SWAT (Soil and Water Assessment Tool), indicate over-proportional runoff-rainfall and under-proportional percolationrainfall relationships. Simulated annual discharge for 2020s will decrease by 2.9% on average (with a decrease of 25.9% for q1 to an increase by 23.6% for q14); for 2050s an average increase by 12.4% (17.6% decrease for q1 to 39.4% increase for q0); for 2080s an average increase of 39.5% (16.3% increase for q1 to an increase of 63.7% for q0). Respective ranges on percolation: for 2020s an average decrease by 0.8% (12.8% decrease for q1 to an increase of 8.7% for q14); for 2050s an average increase by 2.5% (10.3% decrease for q1 to 15.4% increase for q0); for 2080s an average increase by 7.5% (0.3% decrease for q1 to 13.7% increase for q0). These over-and under-proportional relationships indicate future enhancement of floods and question sufficiency of groundwater recharge.

The Upper Kharun Catchment (UKC), which is part of the new State Chhattisgarh formed in 2000, features considerable population growth, expansion of urban areas and dynamic changes in irrigation infrastructure as well as irrigation practices (spatial extension, temporal intensification, increasing use of groundwater as source) for meeting the increasing food demand. Water intensive rice is the major crop of the area. UKC has a comprehensive canal irrigation system which provides the link to water supply from reservoirs fed from areas outside the UKC. However, water provision for irrigation via the canal system for irrigation is restricted to only post-monsoon season. As a consequence, groundwater remains the only source of irrigation water in summer and winter seasons. Improved electricity facilities and subsidy on groundwater pumping have triggered an enormous increase in groundwater withdrawals. Remote sensing satellite images along with ground observed data were used in this study to spatially identify the areas with canal and groundwater irrigation. Results reveal that in 2011, around 50% of the area of the UKC benefits from canal irrigation, whereas 29.8% area is irrigated by groundwater. Around 103 villages in the UKC have no canal infrastructures. 216 villages in UKC are considered as ‘hotspot areas’ because of high groundwater withdrawal (irrigated area exceeding 75 ha per village), There has been threefold increase in groundwater irrigated area in UKC between 1991 and 2011. The upward trend of groundwater use indicates an alarming situation towards over-exploitation and creates the need to provide and analyze data on the use of groundwater resources in the area in order to detect past and to estimate future trends referring to groundwater withdrawals. These data are a prerequisite for enabling careful and foresightful management of groundwater resources especially at spatially identified hotspot areas towards ensuring sustainable management of this resource.

Monitoring the qualitative status of freshwaters is an important goal of the international community, as stated in the Sustainable Development Goal (SDGs) indicator 6.3.2 on good ambient water quality. Monitoring data are, however, lacking in many countries, allegedly because of capacity challenges of less-developed countries. So far, however, the relationship between human development and capacity challenges for water quality monitoring have not been analysed systematically. This hinders the implementation of fine-tuned capacity development programmes for water quality monitoring. Against this background, this study takes a global perspective in analysing the link between human development and the capacity challenges countries face in their national water quality monitoring programmes. The analysis is based on the latest data on the human development index and an international online survey amongst experts from science and practice. Results provide evidence of a negative relationship between human development and the capacity challenges to meet SDG 6.3.2 monitoring requirements. This negative relationship increases along the course of the monitoring process, from defining the enabling environment, choosing parameters for the collection of field data, to the analytics and analysis of five commonly used parameters (DO, EC, pH, TP and TN). Our assessment can be used to help practitioners improve technical capacity development activities and to identify and target investment in capacity development for monitoring.

This chapter highlights the key dependences, linkages and challenges of water resources management. (Many of these issues discussed are revisited and illustrated in the following chapters.) The first part introduces surface and groundwater management in the terrestrial part of the water cycle. Comprehensive presentations of key hydrological phenomena and processes, monitoring, assessment and control are followed by overviews of dependences, linkages and challenges. The manifold facets of intensive human/resource interaction and inherent threats to the resources base are exposed. Both sections present examples illustrating differing contexts and options for solution. The second part summarizes the main drivers and challenges of contemporary water resources management and governance. It provides a critical overview of different water discourses in recent decades. The role of benchmark and recurring water events, their declarations and intergovernmental resolutions are analyzed, and the key concepts and methods of implementation are discussed.
