India’s Land Restoration Opportunity | Madhav Pai | TEDxIITDelhi
TEDx Talks· 2025-12-12 17:58
Land Degradation & Restoration Opportunity - 50% of the land in Badwani district is unproductive due to water erosion, reflecting a widespread issue across India [1] - India has 100 million hectares (247 million acres) of land suitable for restoration through forest protection and landscape restoration [3] - Restoration has the potential to improve incomes for 700 million people in India who depend on the land [3][17] - Restoration could sequester 3 to 42 billion tons of above-ground carbon by 2040, aiding India in meeting its NDC commitments [3][17] Restoration Approach & Implementation - Restoration involves landscape principles, topography, and geology, considering both development and conservation [4] - Interventions should be community-driven and locally led, adapting to each village's unique challenges and ecology [6][5] - An integrated approach to restoration includes soil moisture conservation, water holding structures, tree-based interventions, and sustainable agriculture [7] - The "right place, right use, right species" mantra guides the selection of forestry plantations (slopes > 25%), horticulture (slopes 10-15%), riparian restoration, open grasslands, and agroforestry [8] - Local wisdom, knowledge, leaders, self-help groups, and farmer producer organizations are crucial for driving implementation [9] Scaling Restoration Efforts - Simplifying landscape restoration plans, codifying them, and making them accessible to local institutions is necessary [13] - Leveraging technology, including geospatial technologies and citizen science tools, is essential for measuring improvements in biodiversity, soil health, and carbon capture [14] - Unlocking working capital and low-interest debt for small enterprises can spur local economies [15]

[Music] We've all heard about it before, haven't we. Um, climate change. You know, I first heard of the subject when I was still in primary school.And many years later after completing my metric, you know, I still ask myself where are the results. Where are the tangible results we can actually see and feel in our communities. Because you know, while the world debates, while our leaders sign papers and make statements, there's been a group of people that have been silently and consistently doing all the work ...
The latent super power in our energy grids | Clyde Mallinson | TEDxJohannesburg
TEDx Talks· 2025-12-12 16:51
Honestly, we couldn't have got the timing better than we've got it. Here we sit with our coal fleet due for retirement anyway. Some of it should have been retired already.So, it's due for retirement. And we sit in the middle of the biggest, most exciting disruption to the energy sector ever. The prospect of abundant, clean, renewable energy for everyone is no longer a dream.It's real. And the concept of people having access to uncapped electricity at no additional cost, it's it's transformative. Now the gov ...

Climate Change Supercharged Deadly Asia Floods, Study Finds
Insurance Journal· 2025-12-12 07:10
Core Insights - Climate change significantly exacerbated severe flooding in South and Southeast Asia, resulting in over 1,600 fatalities and approximately $20 billion in damages due to three tropical cyclones in November [1][2]. Climate Impact - Warmer Indian Ocean waters, approximately 0.2°C above long-term averages, contributed to the intensity of Cyclones Ditwah and Senyar by providing additional heat and moisture [2]. - Without human-induced climate change, ocean temperatures would have been about 1°C cooler, indicating a direct link between climate change and increased storm severity [2]. Urbanization and Environmental Factors - The combination of climate change, seasonal weather cycles, and rapid urbanization, along with widespread deforestation, intensified the flooding, with water levels exceeding expected heights during the monsoon season [3]. - Researchers noted that while flooding is typical during monsoon season, the levels reached in some areas were unprecedented, exceeding 14 to 15 feet [3]. Climate Model Limitations - Current climate models have struggled to accurately predict the rapid pace of climate change and its impacts, particularly since 2022, leading to economic challenges for insurers and financial firms [4]. - The inconsistency in major climate models regarding rainfall increases from the cyclones suggests a need for improved models that can better capture regional dynamics [3][4]. Historical Weather Analysis - An analysis by ClimaMeter indicated that meteorological conditions during Indonesia's floods were up to 7 millimeters a day, or 15%, wetter than historical averages, underscoring the influence of climate change [6]. - The attribution group expressed low confidence in their findings due to the rarity of similar events, but noted that natural climate variability played a minimal role in the floods [7]. Increasing Extreme Weather Events - Research indicates a growing trend of extreme rainfall events in Southeast Asia over recent decades, aligning with the findings of the recent floods [7].

The shift from finite capital to infinite resilience | Leanne Emery-Hunter | TEDxJohannesburg
TEDx Talks· 2025-12-11 17:12
Key Arguments - The current financial architecture is not designed for a world of constant crisis, reacting instead of anticipating risks [6] - South Africa needs hundreds of trillions of US dollars by mid-century to tackle climate change [7] - The Just Energy Investment Plan estimates a need of $98 billion over the next 5 years to transition to a low-carbon economy [7] - Of the $11.5 billion secured for the Just Energy Transition, only 7% is in the form of grants, while over half are loans [8] Financial Resilience & Investment Strategies - Financial resilience is defined as the ability of markets to adapt to and absorb shocks while maintaining sustainability and growth [6] - Catalytic capital is essential for absorbing risks and unlocking further investment [8] - The Galapagos Islands debt-for-nature swap demonstrates how layered funding models (donor grants, concessional loans, institutional investment) can turn debt into climate action [15][16] - South Africa's Green Outcomes Fund has leveraged 100 million rand in public money to create four times that amount in private sector funding for small green jobs [19] Recommendations for Systemic Change - Build capacity in communities for governance and finance, and in investors for local context [20] - De-risk resilience investments through guarantees, public funding, and concessional loans [21] - Make resilience attractive by lowering interest rates for climate outcomes and rewarding long-term sustainable views through policy and pricing [21] - Governments need to provide clear policy signals, structure catalytic funds, and simplify processes to facilitate the flow of funds to investable projects [23]
