Bijesh Mishra, Omkar Joshi, Rodney E. Will Ph.D. Student, Assistant Professor, Professor Department of Natural Resource Ecology and Management, Oklahoma State University Abstract The forest-grassland ecotone in the southcentral US is the tension zone between two major biomes and provides a number of important ecosystem services. Active management in the region using prescribed fire, forest thinning/harvesting, grazing, and herbicides can optimize desired benefits for landowners with a variety of management objectives. However, periodic severe droughts that plague this area and increasing climate variability have profoundly affected the productivity, resilience, and stability of ecosystems. We aim to facilitate sustainable management…
अध्येता भन्छन्- काठमाडौंको तापक्रम ‘स्याचुरेसन पोइन्ट’ मा पुगिसक्यो दिवाकर प्याकुरेल२०७६ असार ३० गते १५:५१ मा प्रकाशित ३० असार, काठमाडौं । काठमाडौँमा उपत्यकामा बस्ने धेरै मान्छेलाई हरेक वर्ष मध्य जेठतिर आफूले आफ्नो जीवनकालकै सबभन्दा चर्को गर्मी भोगेको महसुस हुन्छ । कहिले मनसुस भित्रिएला र अलिकति राहतको सास फेर्न पाइएला भन्ने चिन्ता गर्दै उनीहरू दिन र रात काट्छन् । काठमाडौँबासीले हरेक वर्ष गर्मी बढ्दै गएको महसुस गर्न थालेका छन् । तथापि उनीहरु यसबारे वैज्ञानिकहरू के भन्छन् भन्ने विषयमा चाहिँ प्रायः अन्योलमै छन् । संयुक्त राज्य अमेरिकाका फरक-फरक विश्वविद्यालयमा कार्यरत र अध्ययनरत दुई नेपाली र एक अमेरिकी अध्येताले विगत १८ वर्षको काठमाडौँको तापमानको…
File image: A view of Kathmandu city As the summer reached its peak this year a few weeks ago, you perhaps felt that Kathmandu has become hotter than before. You might have spent many hours restlessly, praying for the monsoon to arrive soon so that you could get some relief from the heat. But, did you know that your feelings are backed by research? A recent study by two Nepali and an American scientists has found that the city’s temperature is steadily rising–this has been the case for at least the past two decades.
ABSTRACT A field experiment was conducted with native soil; sewage sludge (SS); horse manure (HM); chicken manure (CM); vermicompost, organic fertilizer and inorganic fertilizer mixed with the native soil. The soil in each of the seven treatments was also mixed with biochar and planted with eggplant. Eggplant fruits were analyzed for vitamin C, total phenols, and soluble sugars. The number and weight of fruits obtained from inorganic treatments were not significantly different from those obtained from organic fertilizer. Concentrations of total phenols were greatest (28 µg g−1 fresh fruits) in fruits of plants grown in vermicompost mixed with biochar compared to…
Abstract The term “urban heat island” (UHI) describes increased surface and atmospheric temperatures in an urban core relative to surrounding non-urbanized areas. Although the phenomenon has been studied to a great extent throughout the world, it is less understood for Kathmandu, Nepal. This study used the Moderate Resolution Imaging Spectro-radiometer (MODIS) 8-day product (MOD11A2) to evaluate land surface temperatures (LSTs), the MODIS-derived Normalized Difference Vegetation Index (NDVI) 16-day product (MOD13Q1) to quantify land surface characteristics, and the MODIS annual land cover classification product (MCD12Q1) to identify major land cover classes. We evaluated the spatial correlation between significant changes in LSTs…
