About the Project
India, as many areas of the world, is experiencing widespread rural to urban migration, coupled with rapid population growth. Taken together, these two factors are resulting in significant land use and land cover changes, causing land degradation in particular in the mountainous Lesser Himalayan regions of Northern India (Tiwari and Joshi, 2012; Khanal and Watanabe, 2006).
The interactions between agriculture and the water cycle present a number of key scientific questions, the answers to which are central to future sustainable food production (Pretty et al. 2010). In India, rain-fed agriculture accounts for ~44% of food production (Sharma, 2011). For centuries, agricultural land management practices have utilised localised irrigation methods of terracing and small-scale onfarm water harvesting to maximise crop yields. Now, with the increasing trend in migration towards urban centres (particularly by younger generations) many of these previously highly managed upland catchments are being partially or completely abandoned (e.g. Khanal and Watanabe, 2006). The impacts of the resulting land degradation on river basin hydrological processes (and hence on downstream water resources, flood risk and sediment transport) are largely unknown.
Changes to the hydrological regime may play an important role in driving such abandonment, with changing hydroclimatology and runoff generation mechanism meaning traditional small scale farms may not be sustainable in areas of rapid agricultural intensification and rising demand for food from a growing population.
Understanding the changing hydrology of agricultural catchments is critically important to issues of water security in the Himalayas. This project will build knowledge through innovative field experiments in the Aglar catchment in northern India
The cost and practical challenges in maintaining remote high spatial and temporal resolution field monitoring in upland environments often limit research studies. In this project you will pioneer the use of low-cost environmental sensors to address such challenges.
Specifically during the project you will aim to:
- Assess the impacts of agricultural land degradation on hydrological functioning in the Aglar river basin, Uttarakhand, India
- Quantify the implications of changing hydroclimatology and runoff generation on sustainable agricultural water management in this Himalayan river basin
- Test capabilities of low cost sensors to monitor hydrological variables in remote mountain river basin
- Reconceptualise interactions and feedbacks in the water-food nexus and their implications for water security and migration in rural India
The project will explore the impacts and drivers of agricultural land degradation through paired sub-catchment studies in the Aglar watershed. By augmenting existing IIT Roorkee experimental monitoring with new low-cost sensor installation, the project will establish high resolution monitoring of degraded, actively farmed and natural sub-catchments. To understand the long-term implications of the findings, new knowledge will be derived from model-based scenario analysis. Specific methodologies will depend on the specific approach you implement; but the basic requirements are:
1. An appetite for fieldwork in remote mountain environments, and openness to explore and work with different cultural communities
2. Ability to conduct spatial and time series data analysis and statistical testing
3. Model development and scenario simulations with a focus on uncertainty propagation
4. Working with stakeholders of different backgrounds and utilisation and communication of local expert knowledge
Training and skills:
Students will be awarded CENTA2 Training Credits (CTCs) for participation in CENTA2-provided and ‘free choice’ external training. One CTC equates to 1⁄2 day session and students must accrue 100 CTCs across the three years of their PhD.
You will work in an international research setting to address urgent research needs in the Himalayan water environment. Collaboration skills will be developed as you will engage with project partners in the UK and India to identify timely, pertinent research questions, develop and implement field campaigns, and disseminate new knowledge to the Indian scientific community. Consequently, you will gain advanced understanding of mountain hydroclimatological and hydrological processes, develop sophisticated technical skills in environmental monitoring, catchment modelling, and become familiar with the research process and its role in informing adaptation decisions in Lower and Middle Income Countries. These skills will be beneficial for multiple future career pathways. The CASE partner, People’s Science Institute’s, also offers PhD training and development support opportunities (i.e. placement opportunities).
Partners and collaboration (including CASE):
The project will be supervised by an interdisciplinary team of international experts from the University of Birmingham, UK, the Centre for Ecology (CEH) and Hydrology, UK, and the Indian Institute of Technology (IIT) Roorkee, India. Extended placement opportunities at CEH and IIT Roorkee are imbedded in the project to undertake analysis/ modelling and fieldwork, respectively.
The People’s Science Institute’s (PSI’s) offers CASE partner support. PSI is a non-profit organization with a mission “to eradicate poverty through the empowerment of the poor and the productive, sustainable and equitable use of available human and natural resources”.
COVID-19 Resilience of the Project:
The COVID-19 pandemic could prevent travel to India to conduct fieldwork. The supervisory team have considerable experience of managing field campaigns abroad from the UK when international travel to remote regions (including the Asian and South America) has not been possible. In this circumstance, you would work remotely (i.e. from the UK) with the IIT and other local partner teams of field scientists based in India. Furthermore, we have some existing field data from IIT projects, an ongoing WMO grant and newly awarded NERC grant that could be utilised.
Year 1: Visit project partners, remote analysis of land use change, design and implement field monitoring
Year 2: Complete field monitoring, data analyses, model setup and application
Year 3: Prepare journal articles and write thesis
The project will require extended periods of field work in India. For these periods (expected to be up to three months at the end of years 1 and 2) you will be based at IIT Roorkee.
