In recent decades, agricultural commodity and food price fluctuations reveal the importance of understanding the agricultural value chain dynamics and making policy recommendations for sustainable development. The modeling purpose in this study is twofold: (1) to understand the price, supply and demand dynamics along the agricultural commodity value chains (2) for the specific case of olive oil value chain in Turkey, to make policy and scenario analysis with the focus of economical sustainability. In line with these purposes, the Agricultural Commodity Value Chain Model is constructed with system dynamics modeling methodology. The model is unique in terms of simultaneously (i) including both the agricultural supply chain and the agricultural value chain structures, (ii) considering the four major market elements, price, demand, supply, and capacity, endogenously, and (iii) considering complex nonlinear relationships among the price levels in different stages of the agricultural value chain. Using this modeling framework and a stylized parameter setting, we first conduct a numerical study and analyze the performance of two sets of value chain interventions, namely, technology investments and financial aid improvements, in mitigating the price fluctuations. Then, the model is adapted to the case of olive oil value chain in Turkey. By utilizing the historical data between years 2007-2018, the model is shown to be valid to represent the behavior of the olive oil value chain in Turkey. Using the validated model, a set of simultaneous policy and scenario analyses are conducted for years 2019-2023 and the impacts of policies on economic indicators are presented.

Turkish olive and olive oil sectoral innovation system: a functional - structural analysis
Pehlivan Gürkan, Nilgün; Erdil, Erkan; Department of Science and Technology Policy Studies (2015)
The main purpose of this thesis is to explore problems that inhibit development of the olive and olive oil sector in Turkey. Olive productivity and olive oil product quality is low in Turkey compared to leader olive producing countries, Spain and Italy. Turkey is at the low end of the global olive oil value chain with high share of bulk olive oil exports and low share of high value added, branded exports. The competition in global markets is increasing and product standards are more stringent. Informal prod...
Generation of food security sensitive regional development strategies through agricultural commodity value chains – case of south eastern anatolia region wheat value chain.
Gümüş, Müg; Pınarcıoğlu, Mehmet Melih; Department of City and Regional Planning (2019)
Currently, dramatic increase in world population, rapid urbanization of world population, changes in food demand and dietary composition, increasing pressure on limited natural resources, escalating climate change effect and fluctuating food prices result in a huge emphasis on food security studies as a contemporary issue .As a subject, food security studies tend to be considered at national or household level in a top-down approach and they are likely to handle the issue as restricted to a single sector (m...
Sustainable design implications for alternative food networks: A case on Güneşköy's community supported agriculture (CSA) model
Kaplan, Ayşe; Doğan, Çağla; Department of Industrial Design (2021-6)
The global food system consists of complex processes (i.e., food production, distribution, consumption, and disposal) and contains several environmental, economic, and social sustainability challenges. As a result of the food system's problems, some producers and consumers have taken actions that have resulted in the emergence of alternative food networks. These are primarily bottom-up initiatives led by creative and innovative groups of people collaborating to develop alternative food-system solutions. Dif...
Estimation of wheat yields by using remotely sensed and modeled agro-meteorological data-driven statistical and crop growth models
Bulut, Burak; Yılmaz, Mustafa Tuğrul; Department of Civil Engineering (2021-6)
Estimation of wheat yield is essential not only for agricultural sectors but also for making economic and strategic decisions at the national level. In this thesis, wheat yield estimation was carried out on the cities and districts where the highest wheat production is made with rainfed agriculture in Turkey and on TİGEM research farms. Two different modeling approaches were evaluated within the scope of the thesis; a statistical multiple linear regression (MLR) model based on analysis of possible agro-mete...
Tarımsal Değer Zincirlerini Sistem Dinamikleri Modellemesi ile Anlamak ve Bir Zeytinyağı Değer Zinciri Uygulaması
Atamer Balkan, Büşra; Meral, Fatma Sedef (NOVA Science Publishers Inc., 2020-04-01)
Agricultural value chains refer to the set of actors and processes that transform the raw agricultural crop on the farm to the final agricultural product on the consumer’s table. Decision making for agricultural value chain development is a complex research problem since agricultural value chains include causal nonlinear relationships, multiple stakeholders with different points of view, and embedded feedback structures. Traditional approaches in the field primarily focus on quantitative and qualitative analy...
