Jhabua, a tribal-dominated district with more than 85 percent population belonging to Scheduled Tribe (ST), is an agrarian district. Water security is, thus, a crucial element for its agriculture-based livelihood economy.

A detailed air emission inventory with a comprehensive list of pollutants within a pre-defined geographical area is beneficial for developing clean air action plans. It can also be used to test the effectiveness of pilot interventions towards air quality abatement.

‘Fleas’ flee the Pashan lake in Pune!

Restoration efforts focusing on desilting and re-contouring of Pashan lake have added to the deterioration of the lake habitat, threatening survival of organisms such as water fleas, warn freshwater biologists Mihir Kulkarni and Sameer Padhye.

The calm waters of Pashan lake in Pune city, seldom give us an idea of the hidden wonders they support. Freshwater habitats like this, harbour a wealth of biodiversity ranging from very tiny/ microscopic plants and animals to larger ones – that reside in and around the waters and depend on it for their food, reproduction and survival.

In the active floodplain area of River Ganga in Eastern India, channel migration and flooding is very common. It is called the Diara region. In the southwest portion of West Bengal's Malda district, after passing the Rajmahal hills River Ganga begins its lower course. India-Bangladesh international border has constrained this region on the south-eastern side.

जलवायु परिवर्तन का मानव स्वास्थ्य पर प्रभाव एवं वर्तमान प्रदूषण रहित चुनौतियां (भाग 1)

जलवायु परिवर्तन से मिट्टी पर पड़े प्रभाव का सीधा असर मानव स्वास्थ्य पर पड़ता है। जलवायु परिवर्तन के कारण तापमान में वृद्धि होती है और वाष्पीकरण का संतुलन खराब हो जाता है व हमारी मिट्टी की आर्द्रता असंतुलित हो जाती है। इसके परिणाम स्वरूप हमें सूखे की मार झेलनी पड़ सकती है। अगर यह स्थिति लगातार बनी रही तो मिट्टी मरुस्थल में तब्दील हो जाती है। मिट्टी एक समय ऊसर व बंजर हो जाती है। अर्थात हमारे पास भोज्य पदार्थ के उत्पादन के लिए पर्याप्त उर्वर भूमि नहीं बचेगी और हमें भूख व कुपोषण की चपेट में आकर अपनी जान गंवानी पड़ेगी। हालांकि यह स्थिति अभी भी बनी हुई है। लेकिन जलवायु परिवर्तन के कारण इसका स्वरूप और विकराल हो सकता है।

भारत में सार्वजनिक स्वास्थ्य पर जलवायु परिवर्तन का प्रभाव

बढ़ते तापमान और मौसम में बदलाव से गर्मी की लहरों और चरम मौसम की घटनाओं की आवृत्ति और तीव्रता बढ़ रही है, जिससे बीमारी, चोट और मृत्यु का खतरा बढ़ जाता है। साथ ही जलवायु-संवेदनशील रोगजनकों के फैलाव में बदलाव आता है, जिससे डेंगू और डायरिया जैसी बीमारियाँ कुछ क्षेत्रों में अधिक आम हो सकती हैं। जलवायु परिवर्तन से फसलों की पैदावार में कमी, खाद्य कीमतों में वृद्धि, खाद्य असुरक्षा और अल्पपोषण का खतरा बढ़ता है। इससे जल सुरक्षा भी प्रभावित होती है। ये परिवर्तन गरीबी, मानव प्रवास, हिंसक संघर्ष और मानसिक स्वास्थ्य समस्याओं को बढ़ा सकते हैं। Rising temperatures and climate change are increasing the frequency and intensity of heat waves and extreme weather events, increasing the risk of disease, injury, and death. It also changes the spread of climate-sensitive pathogens, which could cause diseases like dengue and diarrhea to become more common in some areas. Climate change increases the risk of reduced crop yields, increased food prices, food insecurity and undernutrition. This also affects water security. These changes may increase poverty, human migration, violent conflict, and mental health problems.
