Landscape economics is a social science focusing on the public preferences for natural and humanistic landscapes, and the preference evolution laws, economic laws of landscape resource consumption and creation activities. The basic problems include evaluation of landscape resource value, optimal utilization of landscape resources, landscape resource development and protection policies, formation and creation of diversified landscape structure. The research methods include investigation of consumers' willingness, experiment and behavioral economics, logical reasoning, and case study.展开更多

The Southeastern Anatolia Project （GAP） region located in southeastern of Anatolia has all of pistachio trees. In other words, pistachio trees have grown only in GAP region. Provinces of ~anliurfa, Gaziantep and Adiyaman are in the GAP region. In this study, we have investigated problems of pistachio farmers in these cities. So, we applied survey to pistachio farmers. Then we analyzed data which we had from the surveys with SPSS. As a result, the farmers have mainly got input problems, marketing problems, processing problems, keeping problems, financial problems, labor problems and managerial problems. As a solution, pistachio farmers must set up cooperatives which help finding inputs, markets, loan, labor, manager them and come up with their problems. Government has to support pistachio farmers and price of pistachio yield, pistachio farmers must have training programs about theirs works. Finally, pistachio nuts of stock market must be surely founded.展开更多

In real-life scenarios, transportation costs can fluctuate due to different factors. Finding optimal solutions to the transportation problem in the context of variations in cost is vital for ensuring cost efficiency, resource allocation, customer satisfaction, competitive advantage, environmental responsibility, risk mitigation, and operational fortitude in practical situations. This paper opens up new directions for the solution of transportation problems by introducing two key theorems. By using these theorems, we can develop an algorithm for identifying the optimal solution attributes and permitting accurate quantification of changes in overall transportation costs through the addition or subtraction of constants to specific rows or columns, as well as multiplication by constants inside the cost matrix. It is anticipated that the two reliable techniques presented in this study will provide theoretical insights and practical solutions to enhance the efficiency and cost-effectiveness of transportation systems. Finally, numerical illustrations are presented to verify the proposed approaches.展开更多
