This project will use state-of-the-art Sentinel-3A land measurements complemented by observations from in situ and airborne vehicles to map the heterogeneity of land surface properties across the Ganges Basin. Novel STFC datasets characterising heat stress, crop water stress and vegetation fire will be generated and used to identify changes in agricultural practises in the region. We will demonstrate how these prototype datasets will support in-country Non-Government Organisations (NGOs) focussed on livelihoods and wellbeing of farming community and their families.The Sustainable Development Goals (SDGs) implemented by the United Nations specify that poor and vulnerable communities must have; a) improved resilience to climate and economic shocks, b) implementation of resilient agricultural practises and c) eradicated water scarcity, by 2030. Furthermore the conservation, restoration and sustainable use of terrestrial ecosystems must be ensured by 2020. These goals epitomise that interventions are necessary to support life on land and reduce poverty and are of particular relevance to rural communities living in the Indo-Gangetic Plain (IGP). Specific issues that these communities need protecting against are; a) an increased rate of urbanisation, b) groundwater decline, c) soil erosion through incorrect agriculture practises, d) illegal crop residue burning and e) rising temperatures due to the changing climate. In response to anthropogenic perturbations to the Ganges Basin surface, Indian academics have joined emerging international efforts to determine how geological, chemical and atmospheric interactions impact the ecosystem using an interdisciplinary monitoring approach through critical zone observatories (CZO). Challenges in monitoring the Ganges basin include a lack of high temporal and spatial resolution data at sub-regional, district -level scales as well as large uncertainties in land surface measurements over the heterogeneous landscape. The use of sensors on-board space- and airborne- platforms to monitor critical zones can provide independent sources of information about the ecosystem and overcome challenges in monitoring processes from the ground. This project builds on work done in a previous STFC 21st Century Global Challenges Exploration collaboration between the University of Leicester and the Indian Institute for Technology Kanpur (IITK). In this project we will employ land measurements from the STFC calibrated space technology, in the form of the Sea and Land Surface Temperature Radiometer (SLSTR) on Sentinel-3A which will be used to map the heterogeneity of the Ganges CZO and surrounding regions. Complementary high resolution sensors on airborne platforms will provide the first in-depth mapping of the CZO from which an understanding of the land-use processes contributing to ground water depletion and crop stress will be identified. Implementation of a high resolution radiometer in the Ganges basin will provide the first opportunity to validate and assess SLSTR measurements in the IGP. Together with other space-borne data, SLSTR will be used to generate prototype information on heat-, crop and fire-stress of which the efficiency will be tested through implementation into land and hydrological models and via community feedback through NGOs. New datasets and knowledge created as part of this project will provide the evidence base for intervention strategies that will feed into targeted policy briefs and recommendations required to protect critical zones across the IGP.

该项目将使用最先进的Sentinel-3A陆地测量，辅以现场和机载飞行器的观测，绘制恒河流域陆地表面特性的异质性。将生成表征热胁迫、作物水分胁迫和植被火灾的新型STFC数据集，并用于确定该地区农业实践的变化。我们将展示这些原型数据集如何支持国内非政府组织（ngo）关注农业社区及其家庭的生计和福祉。联合国实施的可持续发展目标（sdg）明确规定，贫困和弱势社区必须拥有；A)提高对气候和经济冲击的抵御能力；b)实施抗灾农业做法；c)到2030年消除水资源短缺。此外，必须确保到2020年陆地生态系统的保护、恢复和可持续利用。这些目标体现了干预措施对于支持陆地生命和减少贫困是必要的，对生活在印度-恒河平原（IGP）的农村社区尤其重要。这些社区需要防范的具体问题有：A)城市化速度加快，b)地下水下降，c)不正确的农业做法造成的土壤侵蚀，d)非法焚烧作物秸秆，e)气候变化导致的气温上升。为了应对恒河流域地表的人为扰动，印度学者加入了新兴的国际努力，通过关键区域观测站（CZO）使用跨学科监测方法来确定地质、化学和大气相互作用如何影响生态系统。恒河流域监测面临的挑战包括缺乏分区域、区级尺度的高时空分辨率数据，以及在异质性景观的陆地表面测量中存在很大的不确定性。利用机载空间和机载平台上的传感器监测关键区域，可以提供有关生态系统的独立信息来源，并克服从地面监测过程中的挑战。该项目建立在莱斯特大学和印度坎普尔理工学院（IITK）之前的STFC 21世纪全球挑战探索合作项目的基础上。在这个项目中，我们将采用STFC校准空间技术的陆地测量，以Sentinel-3A上的海洋和陆地表面温度辐射计（SLSTR）的形式，用于绘制恒河CZO及其周边地区的异质性。机载平台上的互补高分辨率传感器将首次提供CZO的深度地图，从而了解导致地下水枯竭和作物胁迫的土地利用过程。在恒河流域实施高分辨率辐射计将首次提供验证和评估IGP中SLSTR测量结果的机会。SLSTR将与其他空间数据一起用于产生关于热、作物和火灾应力的原型信息，将通过在土地和水文模型中实施以及通过非政府组织的社区反馈来测试其效率。作为该项目的一部分创建的新数据集和知识将为干预战略提供证据基础，这些战略将纳入有针对性的政策简报和建议，以保护整个IGP的关键区域。
