Kolkata: According to a new study, nearly half of India’s total geographical area is prone to invasion by alien plant. It shows that biodiversity hotspots in India are “especially vulnerable” and limiting human interference in remote forests is necessary.

Scientists from North-Eastern Hill University (NEHU), Shillong, have created the first pan-India catalogue of regions most susceptible to invasion and identified the ‘hotspots’.

‘Hotspots’ are regions that are climatically and geographically most suited for alien invasive species – species which colonise, spread and invade new territories.

“Almost half of the total geographical area of India is prone to invasion by alien plant species with moderate and high levels of climatic suitability,” Saroj K. Barik, co-author of the study and a professor at the Centre for Advanced Studies in Botany, NEHU, told IANS.

In India, alien plant species constitute 40 percent of the total plant diversity, of which 25 percent are invasive (such as Siam weed, bitter vine, water hyacinth and mesquite).

Alien invasive species threaten the biodiversity hotspots, he said.

Key findings show most ecologically sensitive regions of India, including the biodiversity hotspots, islands, coastal forests, freshwater swamp forests, mangroves and protected forest reserves, croplands, rangelands and village biomes coincide with the identified ‘invasion hotspots’, indicating their vulnerability to alien plant invasion.

Barik said more than half of the geographical areas of Andaman and Nicobar Islands, Andhra Pradesh, Assam, Dadra and Nagar Haveli, Daman and Diu, Goa, Kerala, Manipur, Meghalaya, Mizoram, Nagaland, Odisha, Pondicherry, Tamil Nadu, Tripura and West Bengal are at “high risk” of being invaded by alien plant species.

Some of the major port towns such as Mumbai, Ratnagiri, Panaji, Nagapattnam, Chennai, Kakinada, Paradip, and Haldia fall within the identified invasion hotspots. Such areas provide suitable habitats for colonisation of alien invasive species after being introduced through shipping routes.

The study (using modelling and GIS data), carried out by Barik, D. Adhikari and R. Tiwary of NEHU is published in ‘PLoS One’ journal and contributes to the comparatively little studied genre of ecological invasion.

Additionally, it sheds light on the fact that remote forest areas with high tree cover and low human population are “unlikely” to be invasion hotspots. This stresses on the necessity of minimum human interference, said Barik.

“Delineating the areas climatically suitable for invasion by diverse species would enable us to gauge the extent of damage the invasive plants can incur to the native biodiversity, assist to identify areas threatened by invasion and facilitate formulation of appropriate policy for their control and management,” said Barik.

Worldwide, alien invasive species cause an estimated annual economic loss of $314 billion in the agriculture and forestry sectors, of which India’s share is around $116 billion.

Oracle Witnessing Double-Digit Growth in India For Past 3 Years

The Oracle Autonomous Database now has the capability to automatically scan for security threats and apply security updates while running to help prevent cyberattacks and data theft

Cloud major Oracle, which is seeing high demand in the Banking, Financial Services and Insurance (BFSI), telecom and manufacturing sectors in India, has witnessed double-digit growth in the country for the past three years, a top company executive has said.

Start-ups and small and medium businesses (SMBs) are fast adopting Oracle’s Software-as-a-Service (SaaS) in the country.

“We are seeing double-digit growth (on an average) in the country. In fact, that’s both in our NetSuite business as well as our enterprise business.

“The India Cloud business is really booming. Overall, the double-digit growth has been there for the last three years in the country, which has been the best-performing region in the Asia-Pacific for us,” Shaakun Khanna, India SaaS GTM Lead, Oracle, told IANS in an interview.

The company competes with major Cloud players like Amazon Web Services (AWS), Google Cloud Platform and Microsoft Azure and provides services such as SaaS, Platform-as-a-Service (PaaS) and Data-as-a-Service (DaaS).

According to Oracle, as a corporation, the firm is on track to become the top SaaS company in the world.

The company offers innovative and proven Cloud suite of SaaS applications that enable customers to transform their business with the latest intelligent technologies such as Artificial Intelligence (AI) and Machine Learning (ML).

“From a perspective of completeness of our enterprise applications, there’s no one who can compare with us. So, that’s pretty much our objective and vision in India as well,” Khanna added.

According to the company, going “autonomous” gave it an edge over rivals in the country.

Larry Ellison, Co-Founder and Executive Chairman of Oracle, in October unveiled the second generation Oracle Cloud with autonomous capabilities, improved security and upgrades for enterprises at the company’s annual user conference “Oracle Open World 2018” in San Francisco.

According to Khanna, autonomous is probably the biggest thing because, with autonomous, the ability to engage technologies like AI, ML, UI-UX, is there.

“I think the other advantage is our diversity, because if you look at it, we are the only company of our stature in the world that has everything — it’s not just the applications that are ours, the hardware, the infrastructure, the database, everything is Oracle,” Khanna noted.

The Oracle Autonomous Database now has the capability to automatically scan for security threats and apply security updates while running to help prevent cyberattacks and data theft.

“If you look at the way Oracle built its first set of Cloud infrastructure is very similar to how Google built it, how Amazon built it, how Microsoft built it, almost everyone built it and we are doing exactly the same.

“Larry and the other founders who started Oracle — they were working for a CIA project and then they came out and started Oracle. So we understand security from our DNA,” said Mitesh Agarwal, Vice President, Key Accounts, Oracle India.

“Almost all of our competitors have never managed to move an enterprise workload to the Cloud — not a single one of them. They all have peripheral applications that have moved to the Cloud. That’s still only about 5-6 per cent of the workloads in the world,” Agarwal informed. (IANS)
