The aim of this paper is to analyse economic sustainability of sunflower production of farmers by comparing farm size, input use level, productivity and gross margin in the Thrace region of Turkey. To reach this aim the primary data were collected by survey with farmers whose main activity was sunflower production in the Thrace region. Edirne, Kirklareli and Tekirdag provinces were selected for representing the region and 80 survey were done by pollsters. The farms were separated in 3-size groups as to its sunflower area sown as small, middle, big farms. According to research results, it was found that wheat-sunflower crop rotation was made by all farms and gross margin in wheat production was higher than sunflower. Sustainability for sunflower production in this region does not depend only on economic parameters, but also on farmer attitudes, necessity of crop rotation and institutional infrastructure. Source


Drought as a natural phenomenon, due to variability of meteorological conditions, strikes worldwide but the severity of its impact depends on the vulnerabilities of water supply systems and economical and sectors as well as on the effectiveness of the adopted mitigation measures. The aim of this paper is to study achieving efficiency and equity in sugar factories and sugar-cropping patterns in Upper and Middle Egypt by focusing on the Strategic Water Shortage Preparedness Plan, introduction methodologies, and specific action to fight drought within the general water-planning framework. The Linear Programming Model was applied to calculate the sugar crops, sugar cane and sugar beet acreage, production, and income of both Upper and Middle Egypt. As a result of an optimal cropping pattern, the cultivation season would lose acreage by 7.260%, farm income increase by 1.774%, water uses decrease by 18.511%, and CO2 emission and energy reduced by 14.96%. Overall, as a result of an optimal sugar-cropping pattern, Egyptian sugar exports would decrease by $130.086 million US. © 2013 Wiley Periodicals, Inc. Source

Agricultural cooperatives have changed considerably in recent decades. In witnessing these structural changes, scholars have proffered analyses of nontraditional ownership models focusing on residual claim rights. However, crucial information on the allocation of control rights in cooperatives is missing. This study sheds light on alternative ownership-control models adopted by agricultural cooperatives in different regions across the world. In each of these models, we describe the allocation of formal control rights with a focus on decision management and decision control rights. We thus provide empirical evidence on the "separation of ownership and control" in agricultural cooperatives. We also analyze each of the governance models in terms of the associated ownership costs, including risk-bearing costs, the costs of controlling managers, and collective decision-making costs. In doing so, we are able to better understand the forces influencing the organizational efficiency of each cooperative model. © 2012 Wiley Periodicals, Inc. Source

The aim of this study is to determine the unit production cost and labor force productivity of tomato in the main production regions. The main material of the study consists of the data compiled by survey studies implemented in provincial directorates of the Ministry of Agriculture and Rural Affairs. As a result of the study, the unit product cost is calculated minimum with 0.10-0.11 YTL/kg in the provinces where industrial tomato production is a widespread activity. The unit cost in table tomato production is minimum in the province of Eskisehir with a value of 0.16 YTL/kg and maximum in the province of Antalya, where production under greenhouse conditions is a widespread activity, with a value of 0.45 YTL/kg. Labor force productivity is maximum in the provinces of Bursa and Antalya and minimum in the province of Balikesir, where tomato is not planted in rotation with other products and where tomato agriculture suffers from various diseases.

During the last decade, an encouraging environment for the restructuring and modernization of the agricultural sector has formed in Greece. The diversification into higher-value crops can be a promising option for small and average-sized farms, particularly during the current economic crisis. One of the most promising alternative crops that have been recently established in Greece is the organic Aloe vera crop. The main advantage of this crop is that it can utilize poor farmlands and, therefore, can facilitate rural development in marginal areas. This study explores the economic sustainability of the Aloe vera crop, considering the embedded risk and uncertainty. The results indicate that organic aloe farming is a promising alternative to "traditional" crops in Greece, particularly for family farms in rural areas. In contrast, this activity is not advisable to the most entrepreneurial type of farmers, unless their crop size allows economies of scales. Finally, the Stochastic Efficiency with Respect to a Function (SERF) analysis associates farmers' risk attitude with their willingness to be involved in organic Aloe vera farming. SERF analysis highlights the crucial role of farmers' risk aversion and concludes that, above a certain level of risk aversion, farmers have no incentive to adopt this economic activity. © 2016 by the authors.
