Risk Assessment & Management of Hydro-climatic Hazards on Natural Resource Degradation & Agricultural Sustainability (IARI:NRM:04)

Indian Agriculture is facing risk on account of changing climate, increasing climate variability and degradation of natural resource. A spatio-temporal assessment of agro-climatic hazards, adaptive capacity  and vulnerability is needed for quantifying the risk and identifying the hot spots. Strategies are required for managing land degradation and shrinking water resources. Recent advancement in geospatial techniques and availability of real time remote sensing data provides an opportunity to develop early warning system and its dissemination for risk reduction. It is necessary to develop knowledge based agricultural services along with a communication backbone for enhancing the knowledge base and dissemination process to the end users. Under this project, the development  & evaluate composite indices, prediction rules, models for risk assessment of biotic and abiotic stresses activity along-with development of  e-resources and web systems for effective dissemination of efficient adaptation strategies has been initiated.

Early warning for yields and pests in crops on spatial scale for their integrated management. Space Application Center, Ahmedabad (ISRO-SAC)

Forecasting of crop yield through remote sensing offers an alternative to the more resource-consuming field measurements and surveys typically used to estimate crop yields at regional to national scales. Models for yield estimation have been developed from empirical to semi physical to physiological growth simulation models. Each approach has its own usability and demerits. The statistical models viz.Regression Models; Time Series Models; Probabilistic Models; Nonlinear Models; Models based on soft-computing techniques (such as fuzzy regression and Artificial Neural Networks (ANNs), integrated models) may be developed and evaluated which may integrated the weather and remote sensing data. Crop yield losses in India due to pests (including diseases) range  from 15-25 %. Loss in yield and quality of crop produce due to infestation of pests (including diseases) could be reduced considerably if their occurrence is known in advance so that timely remedial measures could be taken. Thus, there is a need to develop forewarning system, which can provide advance information for outbreak of pests. Weather plays a vital role in development of pest infestation in crops. Therefore, a technique for forewarning crop pests may be obtained on the basis of weather variables. Limitation of forewarning models for specific geographic locations could be overcome by use of satellite-driven weather and agromet data products. Resultant systems shall enable appropriate agro-advisory to minimize application of chemical pesticides, losses due to pests, financial burden and environmental cost.

DST- ICRISAT centre of excellence on climatic change research for plant protection: Pest and Disease management for climatic change adaptation funded from DST, New Delhi (CCPI)

Climate change and annual climate variability will exacerbate existing vulnerabilities of resource-constrained farmers who depend on agriculture for a living. On average, 30–50% of the yield losses from agricultural crops are caused by diseases and insect-pests. Increase in the frequency of climate extremes, especially temperature and rainfall, are likely to influence the distribution, establishment, epidemiology and management of plant diseases and insect-pests and fuel the losses manifold. Focused R&D is therefore needed to generate strategic knowledge on the changes in diseases and insect-pests dynamics with changing climate and accordingly modify crop protection strategies. This project will address the impact of climate variability on the population dynamics of diseases and insect-pests with the ultimate objective of contributing to adaptation and mitigation strategies towards climate resilient agriculture. The key focus of the Center of Excellence will be to: (i) Generate appropriate databases (on weather and targeted diseases and insect-pests); (ii) Identify hot spots and develop GIS-based risk maps (spatial and temporal) for targeted diseases and insect-pests; (iii) Develop weather-based forewarning system and plant protection advisory tools; (iv) Generate strategic knowledge on the effect of climate variability (increasing temperature, CO2 and rainfall) on population dynamics, host plant resistance, resistance mechanisms to develop adaptation strategies through simulation modeling; and (v) Enhance the capacity of various stakeholders such as researchers, extension personnel, farmers, and students on suitable plant protection and adaptation strategies for climate resilient agriculture.

The process for establishing the future direction to the Library began with re-evaluating the traditional library model. The developing revolution in the technology of on-line storage, display, and communication will make it economically possible to place the entire contents of a library on-line, accessible from computer networks located anywhere, with a hardware cost comparable to operational budget of that library. Digital technologies and online access to information resources have brought increased expectation from library and information services. For researchers, fast access to existing scientific outputs and archived scholarly information on their topic of interest is as crucial as current scientific knowledge. The modes of services that librarians and information professionals provide has thus become very important and have undergone fundament changes over past few decades. Thus institutional repository provides alternative source of scientific information to support our quality research and teaching. To create dependable digital storage and an efficient Integrated Content Management System (ICMS), an open source software can be utilized / customized to meet the requirements of individual NARES Institutes. It can provide Improve Accessibility, Enhanced Search ability, Preservation and Content Selection through the digital repository. Digital resources, digital services and access technologies continue to create new opportunities, new challenges and new expectations. Union catalogue, digital repository and digital libraries are the new paradigms to facilitate researchers, teachers, students, extension professionals.
