Agricultural sustainability is an important parameter for policy design. The primary variables for agricultural sustainability, like available arable land and water, depend on competing demands from other sectors as well as natural factors like climate change. The other critical factor that determines sustainability is demand, which changes with population and dietary habits. The supply also depends on external sources (import); thus a comprehensive and quantitative assessment of sustainability is a major scientific challenge. Here we present an assessment of agricultural sustainability for India. Import requirement, potential surplus and sustainability index are used to estimate India's food sustainability.Keywords

India has witnessed a rather rapid, and often unplanned, urbanization. At the same time, the country is expected to have the largest concentration of mega cities in the world by 2020. Thus development of and redesign (retro-fitting) of 'smart cities' has emerged as urgent requirements. However, the design parameters for a smart city are rarely defined, let alone quantified. A smart city, as a sustainable habitat, is characterized by many, often competing, parameters that require constrained optimization, which appears lacking in the current approach. A matrix for a smart city is proposed to argue that a comprehensive, sustained, integrated and critical R&D effort is required for the design and development of a smart, livable city.- Dynamical Formalism for Assessment and Projection of Carrying Capacity in Different Socio-Climatic Scenarios

Increase in demand, decline in primary resources and impact of climate change make agricultural sustainability a complex function of many variables. A major gap is a consistent and quantitative formulation for assessment and projection of sustainability. We consider agricultural self-sustainability, defined as the condition of minimum food requirement from domestic production, and present a dynamical model of evolution of its constrained dynamics. The model is then applied to estimate and project agricultural self-sustainability, carrying capacity and import requirement with India as a case study in different socio-climatic scenarios. Unconstrained productivity is considered to determine technology demand for different scenarios.Keywords

Small cardamom is an economically important spice crop. However, cardamom is susceptible to several diseases that significantly reduce yield. Proactive prevention of these diseases based on advance warning can enhance the efficiency of disease control and reduce environmental load of pesticides. Many of these diseases are governed by weather variables (for example, through control of fungal growth). This work presents a disease (capsule rot of cardamom) forecast model based on a set of meteorological variables.While no single weather variable provides successful simulation, an optimal combination of weather variables provides sufficient skill for advance warning of the disease.Keywords

Advance and accurate forecasts of air pollutant concentrations have many applications at different scales, from traffic planning to health advisories. However, such models need to incorporate local factors and must be validated against local observations for applicability. It has been shown earlier that a dynamical model successfully simulates, in forecast mode, the observed (CPCB, India) daily concentrations of SPM, RSPM, SO2 and NO2 over Delhi. The present work shows that the model skill is also significant in predicting CO. Together with our earlier results, the present work to the robustness and enhanced scope of dynamical forecast of air pollution.Keywords

Science and Technology (S&T) have emerged as major drivers of innovations and enterprise at present. Thus a systematic and focused effort to utilize S&T in enterprise holds the promise of revolutionizing the economic and industrial landscape of country. However, this potential of S&T-driven enterprise has not yet been realized in India, primarily because a complete ecosystem for such a Science and Technology Enterprise Partnership (STEP) has not yet been identified, let alone established. With the increasing role of S&T in all aspects of society and economical activities, there is an urgent need to develop a comprehensive framework and policy for S&T driven enterprises. It is clear that such an effort must identify all components, and integrate them in an effective framework for a successful STEP, beginning with a clear statement of vision and goal.- Quantification of Regional and Global Sustainability Based on Combined Resource Criticality of Land and Water

The overall global food sustainability is limited by the simultaneous availability of primary resources at regional scales, although the international trade network can redistribute available (surplus) food. Assessments based on isolated resource (like water) or demand (like food) cannot provide correct estimates of sustainability. We define a novel criticality index on the basis of simultaneous regional availability of arable land and water to quantify sustainability. Analyses at regional and global scale show that while a relatively small fraction of world population is subcritical in terms of food availability, much larger fractions are becoming subcritical in terms of food production. The combined resource criticality implies stronger constraints for sustainability.Keywords

Many social processes, from elections to terrorism, depend on growth of memberships to opinions. In a generic sense, an opinion is a proposition that for an individual has financial, cultural and emotional impli-cations. The individual responses in turn create a ‘social response’ which influences the individual response resulting in a dynamical system with two-way feed-backs. We consider a set of deterministic dynamical equations that describe individual response to a class of prescribed opinions. The time-dependent opinion dynamics model exhibits nearly complete acceptance to nearly complete rejection with complex evolution, providing the framework for a mechanistic descrip-tion of opinion formation.Keywords
