اردو اور ہندی کا لسانی رشتہ

موضوع 11:اردو اور ہندی کا لسانی رشتہ
ہندی کیا ہے؟
اکثر ماہرین زبان اس بات سے اتفاق کرتے ہیں کہ کھڑی بولی ہندوستانی کا دیوناگری روپ ہے۔ جس کی ابتداء فورٹ ولیم کالج سے ہوئی۔ موجودہ ہندی کے بارے میں یہ رائے صرف قیاس پر مبنی ہے۔اس سے پہلے کوئی تاریخی اور لسانی استدلال ایسانہیں ملتا جو ہندی کو کھڑی بولی کی روایت سے جوڑے۔دیو نام یا نام دیو اور کبیرداس کی شاعری لسانی اعتبار سے اپنے عہد کی کھڑی بولی میں سے ہے۔محض رسم الخط کی بنیاد پر اسے ہندی کی ادبی روایت نہیں کہا جا سکتا۔بالکل پدماوت، چتروالی (کتابوں کے نام) کی طرح جو اردو رسم الخط میں لکھی گئی ہیں لیکن اردو نہیں ہیں۔
بعض ماہرین ہندی کا خیال ہے کہ ہندی کی ابتدا دسویں صدی عیسوی یااس سے پہلے ہوئی۔اس نظریے کی حمایت میں جو تاریخی اور لسانی استدلال پیش کیے گئے ان کی صحت پر شبہ ہے۔ دراصل یہ غلط فہمی لفظ"ہندی" سے ہوئی جسے مغربی اور مشرقی ماہرین لسانیات نے ہند آریائی زبانوں کے مطالعے میں کثرت سے استعمال کیا ہے۔گریسن اپنی گروہ بندی میں وسطی اور اندرونی حلقے کی زبانوں کو مشرقی ہندی اور مغربی ہندی کہتا ہے۔ ماہر لسانیات ڈاکٹر سینتی کمار چیٹرجی بھی مشرقی ہندی اور مغربی ہندی کی اصطلاحیں استعمال کرتے ہیں۔اسی لفظ کو ہندی والے لے اڑے۔ انہوں نے تصور کرلیا کہ بہت پہلے قدیم ہندی ایک زبان تھی جس کی مختلف بولیوں کو بعض لسانی خصوصیات کی بنیاد پر مشرقی ہندی اور مغربی ہندی میں بانٹ دیا گیا۔اسی لیے اہل ہندی کی اکثریت آج بھی برج، فوجی، بندیلی اور اردو یہاں تک کہ بوجھ پوری، اودھی، راجستھانی اور پنجابی وغیرہ کو ہندی کی بولیاں قرار دیتی ہے۔ لیکن اس قیاس کی کوئی لسانی توضیح نہیں ہے۔ زبانوں کی اس فہرست میں اکثر وہ زبانیں ہیں...

Water Sharing Conflicts and Management in the Indus River Basin

Sharing water resources within country and amongst transborder countries often create conflict because of increasing demand of fresh water for their domestic, industrial and agricultural sectors due to growing population and increasing economic activities. As a result, every country is interested to build more water storages like dams and barrages to safeguard their water requirements in the lean periods or to protect their areas during flood period. Therefore, a transboundary conflict amongst riparian countries on water sharing is obvious facts which are resolved either through bilateral dialogue or by involving international arbitrators. Similarly, a conflict of water sharing within a country has also been serious issue particularly during drought and lean period resulting political conflicts and obstacles in construction of dams and reservoirs. Pakistan is country of 207 million populations, the sixth of the most populated country of the world has been facing transboundary water sharing conflict with India while within a country inter provinces mistrust over water distribution has created reservation over the construction of new water storages. Pakistan has two agreements which provide legal framework for water distribution and management. Indus Water Treaty is an international agreement signed in 1960 between India and Pakistan and other is national agreement amongst the provinces called Indus water accord signed in 1991 by province. Despite several reservations and hostile territorial conflicts between India and Pakistan the Indus water treaty has been successfully functioning in managing water distribution of Indus River and its eastern tributaries originate from Indian occupied Kashmir. Similarly, Indus water accord 1991 provides a mechanism to resolve water sharing conflicts amongst provinces.

Assessment of Synergies of the Synchronized Biodiversity of Wheat and Sugarcane Crops in Faisalabad District

The diversity of macroinvertebrates assemblages in wheat-weeds and sugarcane-weeds agroecosystems were recorded. In addition, phytochemical potential of weeds recorded from both crops were determined to evaluate assessment of synergies of the synchronized biodiversity of wheat and sugarcane crops in Faisalabad district. A total of 72 species of macroinvertebrates (n=4228) were recorded from wheat-weeds agroecosystem. Of these, 58 species inhabited both wheat and weeds while the remaining 14 were recorded only from weeds. Arthropoda (92.41%) and the Mollusca (7.59%) were most recorded macro-invertebrate taxa. Hemiptera (29.09%), Coleoptera (24.77%), Diptera (23.07%), Orthoptera (5.34%) and Pulmonata (8.69%) were the dominant groups of macroinvertebrates in wheat. Diptera (30.92%), Hemiptera (26.49%), Coleoptera (13.53%), Hymenoptera (9.97%) Pulmonata (6.81) and Orthoptera (6.16%) on the other hand, were the most recorded macroinvertebrates on wheat weeds. A higher number of macroinvertebrates (n= 2930) was recorded at the edges in comparison to the centers (n= 1298) of wheat fields. The diversity (H′), richness (S) and evenness (E) indicated a highly significant difference in species composition in most of the habitat combinations. A total of 232 species of macroinvertebrates (n = 5665) were recorded from sugarcane- weeds agroecosystem. Of these, 53 were recorded only from sugarcane while 61 were recorded exclusively from weeds. Arthropods were the most abundant group of macroinvertebrates collected from sugarcane (94.26%) and its associated weeds (98.22%). Hemiptera Coleoptera, Diptera, Orthoptera and Araneae collectively constituted 82% of the macroinvertebrates. A comparison of the diversity (H′) values indicated a highly significant difference in species richness (S) and evenness (E) in all the habitat combinations. The diversity (H′), richness (S) and evenness (E) were higher at the edge than the center of both habitats under consideration.Seeds of fifteen weeds and vegetative parts (roots, stem, and leaves) of seventeen weeds were subjected to analysis to evaluate their phytochemicals. Flavinoids, saponins, tannins, steroids, glycosides, alkaloids, anthrequinones and terpenoids were recorded. This baseline study documents that weeds provide phytomorphic heterogeneity for heterogeneity of macroinvertebrates feeding, breeding and over wintering and taking refuge in various niches. They seem help in maintaining a balance between predator-prey population dynamics and in turn, warrant sustainable crop production with least amount of pesticides and fertilizers used. The weeds that are already being used as traditional medicines could have great economic potential to be used as synergizers fortifying the wheat flour quality (as seeds) and green manure as well.
