The unique climatic and edaphic characteristics of India assist biological invasion by alien species like the vilayati keekar or Prosopis Juliflora that damage native diversity. Control methods for eradicating the species have proved futile. Although the biocontrol efficiency of Cuscuta reflexa has been established, the agent requires further trials for successful deployment.
Flood is a complex outcome of an interface between geological, physiographical, hydrological, meteorological and anthropogenic dynamics. It mandates high computational techniques for the analysis of a large volume of hierarchical pictorial data. GIS technology, inseparably interleaved with remote sensing, helps to panoramically beam complex issues involving river floods and the feasibility of detecting and mitigating them.
g-Governance can be described as a geospatial plugin to e-Governance, acting as an extended module with the additional functionality of geospatial technology. The article explains the genesis and geospatial constituents that are required for the implementation of g-Governance in India.
Trapped by the inversion of temperature, a characteristic feature of winter, along with burning of stubble and fire crackers, pollution exacerbates in Delhi, calling for urgent and effective countermeasures for abatement.
One of the oldest mountains of the subcontinent, the Aravalli play a significant role in arresting the onslaught of the deserts from western Rajasthan and beyond, apart from preserving the rich cultural heritage. Critically, the ranges also recharge the depleting aquifers of the region.
Remote sensing and GIS can be used to generate data that can help achieve sustainable management of natural resources. Maps created through a GIS interface provide a fillip to analysis and bring us a step closer to visualising the complex patterns and relationships that characterise real-world planning and policy problems.
Kerala has witnessed one of the most devastating floods in history. Many lives and livelihoods were lost in just a few days. To reduce future occurrences and the impact of such calamities, it is important that we focus on implementing and improving the measures that can offer greater resilience.
India is among the few nations that have an unbroken history of conducting fair and regular elections. While the credit of a sustained electoral politics goes to the citizens of the country, the definition of a citizen has itself remained debatable and is likely to determine the course of 2019 General Elections.
Electronic voting machines have transformed the system of voting world over. The machines have undergone multiple changes since its inception and even today continue to evolve. In India, EVMs have ensured free and fair elections which are essential to maintain the democratic culture of the country.
While debates around the relative advantage and disadvantage of electoral systems have usually centred on First-Past-The-Post and Proportional Representation Systems, both these need to be revisited in the context of India.
