Bore-well pooling: An answer to managing dwindling groundwater resources in the hard-rock aquifer regions
With a goal of rebuilding the capitals of the agrarian communities in the semi-arid, the WOTR team in Telangana has brought together farmer groups from 4 villages in Talkondapally, block of the Rangareddy district, under a groundwater-pooling scheme. While several such groundwater-pooling models exist across India, this model focuses on connecting borewells through a uniquely designed drip irrigation system – adding to water use efficiency as well as ensuring better management of groundwater.
Semi-arid regions have problems of water scarcity, droughts even floods due to climate variability, but high rainfall areas with ample water bodies are prone to frequent floods and arid regions have scanty rainfall and face water shortages all year round. The point of stating these issues is that adaptation has a different meaning for different types of regions.Thus, the costs of adaptation will differ as well. Areas prone to climatic disasters will require higher investments towards adaptation than the figures in this blog and vice versa. The idea of putting a small village like Bhojdari at the center of this study is that the adaptation figures here can serve a proxies for other similar area and it could also serve as a benchmark to determine what costs go into building adaptive capacities in disaster prone areas.
The groundwater pollution is a serious concern worldwide. The geogenic (natural phenomena) and anthropogenic pressures are major reasons for groundwater pollution. However, in arid and semi-arid regions, pollution is mainly aggravated due to anthropogenic activities. It can be further exacerbated in future due to climate change and it’s variability.
The proper monitoring and treatment of contaminants for groundwater are absolute necessary to avoid risks to health, agriculture productivity and environmental degradation. It also calls for giving high priority to its protection and enhancement in the wake of future climate externalities. This blog post highlights the approach that WOTR has undertaken to bridge the gaps in existing water quality monitoring, assessment programmes and its communication with local stakeholders in India. It provides insights from the current study on preparation of groundwater quality index in Upper Godavari River basin, Ahmednagar.
WOTR developed a tool called Community Driven Vulnerability Evaluation-Programme Designer (CoDriVE-PD) that clearly identifies the need to factor in an evaluation of all such key vulnerabilities at an early stage in the project design and subsequently integrate these variables within the project framework, so as to minimize adverse impacts and thus, have better control of the project and the achievement of desired outcomes.
The elixir of happiness or satisfaction has kept human kind guessing from times unknown. From the realms of philosophy, the question has transcended social fields and moved into the boundaries of science. Each discipline has tried looking at the concept with ideas and expertise of its own—exploring different angles to the same Delphic topic.
WOTR conducted a study to understand the current status of land degradation, its causes, farm management practices employed by people and the perceived impacts of the varying climatic conditions. The study was conducted in 21 villages spread across three districts in Maharashtra- Ahmednagar, Dhule and Jalna. Ten percent farmer households from these villages were interviewed.
It’s getting hot in here: Exploring how different housing structures and livelihoods affect vulnerability to heat-waves in rural India
The year 2016 was the warmest year ever recorded globally according to the Indian Meteorological Department (IMD).The effects of these rising temperatures are felt acutely in Vidarbha region of Maharashtra, India where heat-waves are a common phenomenon. The impacts of these heat-waves are understudied as most existing studies focus primarily on urban areas.
Our perceptions and plans to address issues revolving around our water resources need to adapt if we are to respond effectively to the challenge of climate change. Most of our surface water bodies and aquifers are stressed not just in terms of availability of water but also at the quality front. The reasons can be attributed to changes in the timing, form and intensity of precipitation; changes in agricultural practices, urbanisation, industrial pollution and the use of surface and groundwater . It has the potential to have a long lasting impact on various ecosystems and their services that we are completely dependent on. The impacts are likely to affect the ongoing and future programs designed to protect water quality, public health, safety and livelihood of people. With this in mind, WOTR’s Groundwater and Ecology team continued to explore villages in their second leg of Mula-Pravara sub-basinal seasonal study to assess the reasons for the declining water quality.
Seeing the trees and the forest; understanding the equal importance of micro irrigation and groundwater management
Over the last half century technological & infrastructural advancements in the form of bore wells, pumping technology and rural electrification, has enabled farmers in the dryland regions of Maharashtra to access and extract groundwater at unprecedented levels, enabling the intensification and extension of cultivation. However, high levels of abstraction accompanied by recurrent droughts have led dramatic declines in groundwater levels. Further the socio-legal paradigm that governs groundwater resources, privileges individual users while ignoring the common pool characteristics of groundwater and aquifers.
Groundwater is an integral part of the hydrogeological cycle and is an important natural resource of great social and economic significance. Today, groundwater resources across the country are under great stress: pollution , over-extraction, increasing stress due to population growth, emerging equity issues and added climate change. In much of Maharashtra, this precious natural resource occurs in weathered and fractured formations of the unsaturated zone. The hydrogeology of Deccan basalt is quite complex. This poses a challenge in identifying suitable groundwater bearing zones and location of recharge sites. Competition for this scarce resource has meant that farmers are drilling more wells of greater depth, leading to a greater disruption in the underground natural hydrological flow. Responding to this challenge requires a two- pronged approach. First, it is important to generate scientific and reliable knowledge that helps stakeholders to access and understand their underground reservoirs (aquifers). Second, an appropriate institutional setup must be put in place to ensure that this knowledge is operationalised in a sustainable and equitable manner. In this blog, we look at some of the work that we’ve been doing on the first front.
