The past 50 years have seen an increased exodus of populations from rural to urban areas. Today, 55 per cent of the world’s population lives in or around cities and this proportion is expected to expand to up to 68 per cent by 2050. There are of course a multitude of reasons for people to leave their rural lives behind and move to urban areas, including socioeconomic and political change, declining subsistence farming, and environmental factors. One effect of this continuous decrease in rural populations is that the land they leave behind leads to a rise in the number of abandoned fields and pastures, forestry areas, mines, factories, and even entire human settlements.
IIASA researcher Gergana Daskalova and Johannes Kamp, a researcher at the University of Göttingen in Germany, took a closer look at abandoned land— in other words land on which human activities have ceased—to explore how biodiversity is influenced, and what this means for ecology and conservation.
“The factors that drive depopulation and consequently also land abandonment are intensifying due to issues such as climate change and the rapidly changing geopolitical landscape. The Russian invasion of Ukraine, for example, has already created new abandonment hotspots. Abandonment is a globally important process. The scale at which this is happening around the world urged us to put the spotlight on the places people have left behind as a potential source of future solutions for conservation, while also protecting human livelihoods,” Daskalova explains.

Enhancing Green Cover in HP
Not too long ago, a vast stretch of approximately ten acres of forest land in Parohi and Sangirthi of Bandladhar in the Bilaspur zone of Himachal Pradesh remained barren. The terrain was rocky, with minimal soil depth, making the idea of growing trees there seem implausible. However, today, this unproductive land is transforming into a verdant landscape, with 11,000 saplings of various tree species taking root. Sarita Brara informs that this transformation is attributed to the state government's Mukhya Mantri Van Vistaar Yojana (MMVVY), which aims to enhance green cover across thousands of hectares of barren forest land throughout the state. The MMVVY was officially introduced in 2023.
AI Writing, Illustration Emits Much Less Carbon than Humans
With the evolution of artificial intelligence (AI) comes discussion of the technology's environmental impact. A new study has found that for the tasks of writing and illustrating, AI emits hundreds of times less carbon than humans performing the same tasks. That does not mean, however, that AI can or should replace human writers and illustrators, the study's authors argue.
Celebrating 'Solar Sisterhood' Power
On International Women's Day (March 8), Ashden highlighted the women who made renewable energy happen especially among the world's poorer communities where energy access posed significant challenges. The theme for this year's International Women's Day was 'Inspire Inclusion.
Redefining Development in Tune with Nature
A worldwide congress of individuals synonymous with practising ancient traditional values in the eastern part of Assam, in northeast India, has emerged as a major platform for converging diverse cultures, emphasizing the preservation of ancient traditions, ecological sustainability, and collaborative governance. Through this article, Nava Thakuria informs us that the 8th Triennial International Conference and Gathering of World Elders of Ancient Traditions also adopted the 'Dibrugarh Declaration, which unequivocally states that ancient wisdom profoundly views human beings as an integral part of the natural ecosystem, rather than as masters.
Surprising Role of Manganese In Soil Carbon Sequestration
A recent study reveals an unexpected link between manganese-a naturally occurring mineral-and increased carbon emissions from high-latitude boreal forests. The study uncovers how manganese increases carbon emissions from boreal forest soil, over time, challenging conventional understanding of the role of manganese in the carbon cycle.
India's Quest towards a Green Future With Green Initiatives and Climate Action
The interim budget of India for 2024-25 has placed significant emphasis on the green economy and investments aimed at combating climate change. These announcements are poised to reinforce India's prior endeavours in this direction. In this article, Sameeksha delves into concepts such as the green economy and climate action, highlighting that through its various initiatives, India has made significant progress towards the target of net zero emissions without compromising its economic development in less than a decade. These steps are expected to have a long-lasting impact, and the rapid growth of the country, coupled with green initiatives, will pave the way for a new era of prosperity.
Indian Forest and Wood Certification Scheme
Dr Krishna Kumari, Forestry Faculty, Pandit Deendayal Upadhyay College of Horticulture and Forestry, Dr Rajender Prasad Central Agricultural University, Bihar along with Supriya Rai, a third-year student pursuing BSc in Forestry at the same university, engage in a discussion regarding the objectives and benefits of the IFWCS.
Decreasing Emissions with Sustainable Practices
In this article, Sanjay Gupta highlights the significant role of the construction sector in global greenhouse gas emissions. The construction industry accounts for 19 per cent of greenhouse gas emissions. These emissions mainly result from energy consumption, material production, transportation, and the construction process itself. Nevertheless, there is optimism for the future, as technological advancements and increasing environmental awareness are driving the transition towards a more sustainable construction industry. Through the incorporation of innovative solutions, this sector has the potential to exert a strong influence on environmental consciousness. For the journey ahead, industry players should come together and unite in taking a collective responsibility against climate change to shape a world that is environmentally pure for generations to come.
