In this study, different types of simulation are also considered in order to test the response of the economy, for that we used two scenario. The principal objective of this simulation is to examine the linkages of agricultural productivity growth on non-agricultural sectors. Model results indicate that a shift in the scale parameter by 10 percent in the value added function pushes total output, exports, imports and consumption up. Increase in output and employment in the non-agriculture sector is also significant. The effects are more positive when tariff is removed. الملخص:الغرض الرئيسي لهذه الدراسة هو إظهار التأثير الاقتصادي لزيادة معلمة كفاءة الإنتاج في قطاع الزراعة على الاقتصاد الجزائري باستخدام تحليل التوازن العام القابل للحساب. في هذه الدراسة، يتم أيضًا دراسة أنواع مختلفة من المحاكاة لاختبار استجابة الاقتصاد،من أجل ذلك استخدمنا سيناريوهين اثنين. الهدف الرئيسي لهذه المحاكاة هو فحص روابط نمو الإنتاجية الزراعية في القطاعات غير الزراعية. تشير نتائج النموذج إلى أن التغير في مستوى المعلمة بنسبة 10٪ في دالة القيمة المضافة يدفع إجمالي الإنتاج والصادرات والواردات والاستهلاك إلى الزيادة. كما أن الزيادة في الإنتاج والعمالة في القطاع غير الزراعي مهمة أيضًا. الآثار أكثر إيجابية عندما يتم إزالة التعريفة الجمركيةItem Economic assessment of resource use in wheat production in Gezira Scheme, Sudan (2014/15)(University of Eloued جامعة الوادي, 2019-10-30) مصطفى حاج, السيد السر; النقرابي, عبدالله; O.

Summary: Tobacco cultivation is one of the most important aspects of the agricultural intensification witnessed in the Wadi Suf area. Which called for the continuation of this boom study and analysis. The study aims to analyze the agricultural policies of the tobacco crop as it is the most important crop intensification in the Wadi Suf area, as well as the industrial crops of strategic importance, and we will use the policy analysis matrix through the technical treatments of the matrix of the tobacco crop. The Policy Analysis Model (PAM), developed by Eric A. Monke and Scott R. Pearson in 1989, can be used not only to measure the comparative advantage (social profitability) of a given activity, but to measure the impact of government interventions, and to estimate the relative advantages of a system or sector Produced, and considered as one of the most important quantitative analysis tools in this field. To produce results that are a set of indicators that assess the role of government policies and accurately determine the relative and competitive advantage of tobacco production in the region.Item (Panel Data)تحليل دوال إنتاج محاصيل الحبوب في الجزائر باستعمال نماذج المعطيات الطولية(University of Eloued جامعة الوادي, 2019-10-30) بوعراب, رابح; فتح الله, مسعودةيكتسي إنتاج الحبوب أهمية كبيرة في الجزائر، نظرا لطبيعة ومميزات المجتمع الجزائري الذي يعتبر الحبوب من بين المنتجات الاساسية واسعة الاستهلاك. لكن بالرغم من ذلك لم يرتقإنتاج الحبوب في الجزائر إلى المستوى المطلوب ولا يغطي إلا جزء ضئيل من الطلب الوطني. وتهدف هذه الدراسة إلى تحليل دالة الإنتاج الزراعي لهذا المحصول عبر بعض ولايات الوطن بهدف تحديد التباين في الإنتاج من خلال تحليل المرونة الإنتاجية والإنتاجية الحدية لمختلف عناصر الإنتاج (المدخلات) بالإضافة إلى تحديد الشكل الانسب للنموذج وفق منهجية البيانات الطولية ذات البعد المقطعي والزمني.

From today. From now on, ICT have become an essential instrument within the reach of companies, allowing the accomplishment of work without constraints of space and time. In addition, ICT is considered as an important factor which contributes to the evolution of companies ( increased profit or productivity, reduced costs and downsizing). ICTs have disrupted the world of work from productive and financial companies, both in management and organization and in the diversity and multiplicity of products. They have made it possible to create new benefits and services for the benefit of customers and new gains for economic and financial companies. ICTs have also enabled the creation of websites for the various economic and financial companies to facilitate the needs and demands of these customers and suppliers. Especially in processing data with efficiency and accuracy. Our research serves to show which ICT tools are used in economic and financial companies and societies? And What is the degree of use and adoption of Information and Communication Technologies (ICT) and their impact on economic and financial enterprises in Algeria?Item The Role of Small and Medium Enterprises in Achieving Sustainable Development of Drinking Water Purification(University of Eloued جامعة الوادي, 2022-06-18) Ali Ahmed, Maher; Mustafa Sajid, NasreenSustainable development represents one of the effective approaches to evaluate performance improvement, as it represents a vital production of its requirements and the most effective element. Therefore, sustainable development is the essence of performance, and there is no performance improvement without sustainable development. The results indicated a lack of concern in the sustainable development process, which was reflected in the organization’s performance and the absence of coordination between administrations and environmental actors, in addition to poor environmental awareness among many social strata resulting in absence of a continuous environmental evaluation, down to the low level of environmental performance. It was also found that most of the enterprises owners are those whose ages range from 20 to 50 years, which indicated that the conducted enterprises are not constrained to a specific age. It is also found that marketing problems have achieved (3.236) with a relative weight of (64.7%) indicating the sample approval on-axis average. The statements' means ranged between (2.94-3.54) with relative weight (58.8%-70.8%) and those percentages showed the study sample's approval on the phrases in an average level concerning the marketing problems.Item Studies of agronomic performance of quinoa (Chenopodium quinoa Willd.)genotypes under arid conditionsof northeast of the Algerian Sahara(Case of Ouedrigh)(University of Eloued جامعة الوادي, 2019-10-30) Oustani, Mabrouka; Halilat, Mohammed Tahar; Mahda, SmailThe varietal behavior of six quinoa genotypes (Giza1, Sajama, Santa Maria, Q102, Q29, Q27 and Q18) was monitored under arid conditions of Ouedrigh region. The adopted experimental device is ofrandom block type (with four blocks).Measurements includedemergence rate, seed yield and thousand kernel weight. The obtained results showed that all the genotypes tested detected an adaptive potential to the extreme edapho-climatic conditions of the arid environment with a high germinating ratefor all genotypes. The best yield was in favor of genotype Q102 (302.21g m-2). While, thelowest yield was recorded by the Santa Maria genotype which recorded a yield of the order of (203.33g m-2). The obtained results show that quinoa holds great promise as a newcropintheagriculturalproductionsystemsinsouthofAlgeriaadaptsverywellwiththepedoclimatic conditions of Algeria.
