Assessing Landslide-Driven Deforestation and Its Ecological Impact in the Western Ghats: A Multi-Source Data Approach

The influence of landslides (LS) on forest structure, composition, and functionality has gained limited scientific attention compared to socioeconomic aspects. This study aims to fill this gap by investigating the dynamics of pre- and post-LS occurrences in and around the Kali Tiger Reserve (KTR), Western Ghats. Our approach integrates multi-source, multi-temporal earth observation data, vegetation indices, field observations, and machine learning techniques.

Body

Prof. M.Jayananda has unique blende of expertise across several disciplines of geosciences including tectonic fabric analysis, petrology, solid earth geochemistry and radiogenic isotopes. He has focused multidisciplinary research on early Earth dynamics, origin of habitable continents, shift from anoxic to oxygenation of Archean ocean, Cenozoic surface dynamics, landscape evolution and topographic build-up in Western Ghats. Recently he has initiated a new study on Trans-Himalaya addressing the magmatism, tectonics, environmental crisis across Permo-Triassic boundary. For the past four decades he has worked in Universities in India (Bangalore University, Delhi University and Hyderabad Central University) and France (Universite de Rennes I) contributing to research, teaching, mentoring PhD, post-docs, outreach, and public engagement. He has also contributed to the global science community as Editor-in-Chief of the International Union of Geological Sciences (IUGS) flagship journal ’Episodes’ 2009-2013, Editor-in-Chief of the Himalayan Geology (2017-), Associate Editor of Journal of Earth System Science (2013-2016), Regional Editor of Gondwana Research (2004-2007), Editorial board member Journal of Geological Society of India (2009-2018), Precambrian Research (2020-) and Jour Asian Earth Sciences (2008-).  He has participated in IUGS programs (IGCP projects), participating in National Committees, outreach activities by delivering lectures at different Universities and as a mentor at Government of India flagship science program of Inspire Camps for high school students. In view of these contributions to research, academics, mentoring of students, capacity building and promotion of science through editing/reviewing, he has been conferred several National Awards, elected to the Fellowship of all the three National Science Academies of India and J.C. Bose National Fellowship.

International Widows' Day

The impact of the loss of a partner is devastating. When it comes to women, it gets magnified due to the long-term struggle for their fundamental rights and dignity. Armed conflicts resulted in displacement, and in more recent times, the COVID-19 pandemic has led to an enhanced number of people losing their partners. In 2010, the UN adopted June 23 as the International Widows Day. What can we do? Be empathetic and understand. Enhance awareness, advocacy, social support, and empowerment, and push governments to implement policy reform.

 International Day for Countering Hate Speech

Hate speech and its impact on society are not new. The scale and impact are increasing due to the emergence of new modes of communication and reaching out to people. The UN launched “The International Day for Countering Hate Speech,” which is observed on 18 June yearly.  Hate crimes are rising and at an alarming pace. It is a double-edged sword. Newer communication technologies like social media enable activists to work for democracy and hate groups.

World Refugee Day

 Every year, World Refugee Day is observed on 20 June. End of 2023, the world has seen ~117 million people displaced worldwide. 40% of them are children.  Prolonged wars, drought, and insecurity are a few of the several reasons why people seek refuge. The world must come together, in the first place, to avoid conflicts and prolonged wars. Organisations must work to ensure the safety of the refugees and build the process for their economic upliftment and social inclusion. The support is needed more than ever. 

United Nations Public Service Day

Effective public administration is crucial for creating a better future for all. Governments struggle to function effectively without capable public administration, hindering sustainable development efforts. Recognising the importance of public service institutions, the UN passed a resolution in 2002 to observe 23 June as "The UN Public Service Day". Though the public trust in governmental institutions is increasing, more needs to be done.

Equity assessment of global mitigation pathways in the IPCC Sixth Assessment Report

This paper analyses 556 model scenarios assessed by IPCC’s Working Group-III for the 6th Assessment Report, which have an underlying 10-region classification and correspond to restricting warming levels to 1.5 ℃ and 2 ℃. We show that across all scenarios, the current global inequalities in incomes, energy use, and emissions, are projected to continue even in 2050. Scenarios also project higher per capita fossil fuel use and lower carbon dioxide removal in developed countries in 2050 compared to developing countries.
