तेहरान जल संकट और ईरान में गंभीर सूखे का प्रभाव
स्रोत:द हिंदू ↗
क्यों मायने रखता है
Highlights the extreme real-world impacts of climate change and prolonged droughts on major urban centers, serving as a case study for water security challenges and the concept of 'Day Zero' in large metropolises. Relevant for questions on global water crises and geographic features of West Asia.
सारांश
Iran is grappling with an unprecedented water crisis and its worst drought in decades, leading to planned periodic water cuts for Tehran's 10 million residents. The critical Amir Kabir dam on the Karaj river is nearly dry, holding a fraction of its normal reserves, leaving the capital with less than a two-week water supply. President Masoud Pezeshkian has raised the extreme possibility of evacuating Tehran if rainfall does not arrive soon. The crisis extends nationwide, severely affecting other major cities like Isfahan, Tabriz, and Mashhad, highlighting the severe vulnerability of the region to climate-driven water scarcity.
मुख्य बिंदु
- ईरान दशकों के अपने सबसे भीषण सूखे का सामना कर रहा है, जिसके कारण तेहरान के 1 करोड़ निवासियों के लिए जलापूर्ति में योजनाबद्ध कटौती की जा रही है।
- President Masoud Pezeshkian warned of a potential evacuation of Tehran if no rain falls by year-end.
- The Amir Kabir dam on the Karaj river, a key water source for Tehran, is running critically low, holding less than a two-week supply.
- Other major Iranian cities, including Isfahan, Tabriz, and Mashhad, are also severely affected by drastic drops in reservoir levels.
- Tehran's geography traditionally relies on winter snow and autumn rain from the Alborz mountains, but this natural hydrological cycle has failed this year.
महत्वपूर्ण शब्द
Amir Kabir Dam
A major arch dam on the Karaj River in northern Iran. It is a vital source of drinking water and hydroelectricity for Tehran, currently hitting historic lows due to multi-year drought.
UPSC context
GS-1 (World Geography); tests understanding of critical global infrastructure and the impact of climate-driven resource depletion in arid regions.
Karaj River
ईरान की अल्बोर्ज़ पर्वत श्रृंखला (Alborz mountain range) में स्थित एक महत्वपूर्ण नदी। यह आमिर कबीर बांध (Amir Kabir Dam) को जल की आपूर्ति करती है और तेहरान के निवासियों के लिए मुख्य सतही जल स्रोत के रूप में कार्य करती है।
UPSC context
GS-1 (Geography); relevant for mapping major hydrological systems and understanding urban dependencies on natural water sources in West Asia.
IRNA
इस्लामिक रिपब्लिक ऑफ ईरान की आधिकारिक, राज्य-संचालित समाचार एजेंसी। सरकार द्वारा नियंत्रित, यह आधिकारिक घोषणाओं और सरकारी मीडिया रिपोर्टिंग के लिए प्राथमिक माध्यम है।
UPSC context
GS-2 (International Relations); important for analyzing state-media narratives and assessing official information channels in Middle Eastern geopolitics.
मसूद पेज़ेश्कियान
The President of Iran (assumed office 2024) who issued a high-profile warning about the potential evacuation of Tehran due to the severity of the country's water crisis.
UPSC context
GS-2 (International Relations); relevant for tracking regional leadership responses to domestic environmental crises and their impact on national stability.
Water Bankruptcy
An extreme ecological state where a region's water demand consistently exceeds its renewable supply, resulting in the exhaustion of natural reserves and failure of management systems.
UPSC context
GS-3 (Environment/Disaster Management); tests knowledge of long-term ecological mismanagement and the socio-economic risks of unsustainable water use.
Water Day Zero
A projected threshold when a city's municipal water supply is expected to be exhausted, necessitating the cessation of piped water and implementation of emergency distribution.
UPSC context
GS-3 (Environment/Urbanization); crucial for discussing urban resilience, climate adaptation, and resource security as a non-traditional security threat.
प्रारंभिक ट्रैप
अल्बोरज़ पर्वत तेहरान के जल विज्ञान को निर्धारित करते हैं और ईरान तथा फारस की खाड़ी के बीच भौगोलिक बाधा के रूप में कार्य करते हैं।
The Alborz mountains run along the northern border of Iran, bordering the Caspian Sea, not the Persian Gulf. The Zagros mountains lie to the southwest.
संबंधित अवधारणाएँ
What are the key geographic mountain ranges dictating Iran's hydrology?
- Alborz Mountains: Runs along the Caspian Sea in northern Iran. It acts as the primary catchment for Tehran's water supply through winter snows and autumn rains.
- Zagros Mountains: Spans the western and southwestern regions of Iran near Iraq and the Persian Gulf, acting as the country's other major climatic barrier and watershed.
What constitutes a 'Day Zero' urban water crisis?
- Defining Day Zero: The projected date when a municipality cuts off piped water to homes, forcing residents to queue at public standpipes for strict daily rations.
- Key Drivers: Triggered by a combination of severe meteorological drought, over-reliance on surface reservoirs, poor groundwater recharge, and sudden climatic shifts (like the failure of seasonal rains).
- Indian Context: Chennai faced a near Day Zero in 2019 when its main reservoirs ran dry, mirroring earlier crises in Cape Town (2018) and the looming threat in Tehran.
अंतर-विषय पैटर्न
Urban Day Zero to Climate Migration
The unprecedented threat of evacuating Tehran shifts the 'climate refugee' narrative from traditional coastal submergence to arid-zone urban water collapse, highly relevant for GS1 urbanization and GS3 disaster management.
Water stress as a threat multiplier
Severe drought and municipal water cuts in cities like Isfahan historically trigger massive internal protests, acting as a domestic vulnerability for Iran amid its wider geopolitical conflicts.
