پروفیسر باور
پچھلے مارچ میں جرمنی کے ہالے یونیورسٹی کے علوم مشرقیہ کے پروفیسر باور کا انتقال ہوگیا، وہ لسانیات کے ماہر تھے، وہ یورپ کی تقریباً جملہ زبانوں کے جاننے کے علاوہ ساری سامی زبانوں سے واقف تھے اور تورانی زبانوں خصوصاً چینی زبان میں خاص مہارت رکھتے تھے۔ اس حیرت انگیز وسیع لسانیاتی واقفیت کے سبب سے وہ راس شمرہ کی کھدائیوں میں بعض نئے خطوں کے کتبوں کے برآمد ہونے پر ان کو حل کرسکے، ماسوف علیہ کو امام غزالی کی احیاء العلوم سے خاص دلچسپی تھی، اس کے متفرق ابواب کے ترجمے اکثر شائع کرایا کرتے تھے، اسلامی علم مرایا و مناظر پر بھی بعض اچھے مضمون لکھے تھے، انسائیکلوپیڈیا آف اسلام کے شریک ناشر بھی تھے اور فلک، حاء، حفص الفرد، وغیرہ عنوانوں پر اس میں مقالے لکھے تھے، ’’حرف تہجی کی ابتداء‘‘ پر ان کی ایک جرمن تالیف اس وقت مطبع میں ہے۔ (سید سلیمان ندوی، جولائی ۱۹۳۷ء)
Paper currency has remained controversial since its advent, until the majority of the modern scholars agreed that paper currency is just like gold and silver, and all the rules and provisions regarding the/of homogeneous and heterogeneous exchange of gold and silver are applicable to paper currency. This viewpoint is widely adopted by prominent modern-day international academies of Islamic Jurisprudence and the same has been preferred by the majority of contemporary scholars in their books, dissertations and scholarly articles. On the contrary, there is a different opinion of majority of the scholars in Indian sub-continent. The reason behind this was that the viewpoint of Ḥanafi school of thought about legal effective cause (᾽illat) of Ribā i.e. Weight is not found in paper currency, so the rules of Ṣarf (Exchange of gold and silver) are inapplicable. So, they opined that paper currency is like Fulūs (metal coins). Furthermore, to stop all the possible ways resulting to/in Ribā according to this opinion, they preferred the viewpoint of Imam Muhammad (R.A) regarding the metal coins and set some precautionary measures. However, the said standpoint has not been deliberated and contested in the contemporary jurisprudential research work as it deserved. This research aims to evaluate this viewpoint in detail, clarifying its roots and evidences while revealing its implications and comparing it with the view adopted by the majority of the contemporary scholars.
Climate change has emerged as a major environmental threat towards the agrarian economy of Pakistan with significant pressures on agriculture production abilities, ecosystem functioning, availability of water assets and also affecting the economic firmness. Increase in atmospheric concentration of greenhouse gases has produced significant effects on the climate of our home land in the coming years and this would transform our normal climate, leading towards extreme weather happenings. The current study traced out the impact of climate change on major crops of Pakistan i.e. wheat, rice, maize, sugarcane and cotton by employing Vector Auto Regression (VAR) model. Yearly seasonal data (from 1983 to 2013) published by the Metrological Department of Pakistan and Agriculture Statistics of Pakistan was used. It was revealed that climate change has significant influence on production abilities of major crops in Pakistan. Temperature variable has lasting impacts on crop production. Average minimum temperature played a positive role towards the production of wheat, maize and cotton while reduced the production abilities of rice and sugarcane crop. In case of wheat it showed about 17 percent increase in production due to minimum temperature and showed about 4 percent increase in cotton production. Average maximum temperature also showed positive effects for cotton and maize crop and reduced the production abilities of wheat, rice and sugarcane crops. Average temperature increased production of cotton and sugarcane and lasted negative impacts on wheat, maize and rice. Average temperature increase from four to five degree till 2030 brought reduction in maize production about 5.8 percent. Rainfall is going to be beneficial for sugarcane crop xxiii production. However, it negatively affects wheat, maize and cotton crop. In case of rice it has a beneficial impact in initial period. However, in the long run, it has a negative impact. Variance decomposition showed that average rainfall has brought about 13 percent variations in cotton production hence creating a negative impact while in case of sugarcane it only showed about 2 percent variation. Water availability significantly added for the entire major crops showing that time availability of the water required fairly enhances crop productions. Fertilizer role towards crop production were also very positive i.e. timely fertilizer application enhanced crop production for all the crops. Augmenting research and development policies, public private partnership are the key options to mitigate the harmful effects. Introducing heat and drought resistant crop varieties, improvement in existing irrigation systems, adjusting timings of cultivation will definitely eliminate the catastrophic effects of climate change.
