“…Dynamic system approaches also allow simulating the evolution of a system over time. This approach has frequently been used to help improve ecosystem management strategies and interventions, for instance, to analyze deforestation dynamics in the Amazon (Portela and Rademacher 2001), water scarcity in Australia (Sahin et al 2015), dissemination of high-quality crop seed in Uganda (Reinker and Gralla 2018), and sustainable agricultural development in Ghana (Banson et al 2016).…”

Growing evidence suggests that constraints to the availability and quality of tree seed can undermine the success of forest and landscape restoration efforts and the delivery of associated benefits such as mitigating climate change and halting biodiversity loss. Past experiences to promote tree seed supply have frequently shown limited outcomes over time, partly because of unexpected, deleterious dynamics that emerged from the interventions themselves. In this study, we used a dynamic system approach to understand the interrelated problems that constrain the supply of good quality and site-adapted tree seeds to meet smallholders' and other stakeholders' demand in Burkina Faso and the Philippines, and to identify leverage points for intervention. Causal loop diagrams were constructed for each country, based on a framework of indicators of effective tree seed supply systems, literature review, semistructured interviews, and expert validation. The diagrams illustrate the complex interactions between planned interventions and their expected and unexpected effects that frequently lead to adverse outcomes. For example, the high turnover of forestry officers in municipalities to combat corruption in Burkina Faso combined with limited resources to support smallholders undermined the officers' ability to strengthen local capacities in seedling production and sustainable forest management. In the Philippines, the imposition of rigid requirements for seedling survival rates as a condition for funding, in the absence of adequate time and resources for the production of quality seedlings and monitoring, resulted in exaggerated survival rates during reporting, which in turn hampered the detection and addressing of shortcomings. A dynamic system approach can help stakeholders recognize the broader impacts of their actions and jointly identify appropriate interventions, from developing more context-specific approaches to reconsidering investment criteria to balance benefits.

“…In [67], the authors argue that system dynamics, a subset of systems thinking signifies variations in a complicated system, and is beneficial for mimicking the stock-flow-feedback processes that usually trigger the behaviour of intricate systems. In [68] the authors argues that the modelling approach depend on the following crucial elements. "Stocks" exemplify the rise of something; "flows" exemplify the rate of flow into or out of a stock.…”

“…According to Sterman, to solve the complex problem of the closed-loop dryland-based catfish supply chain in Gunungkidul Minapolitan by using the system dynamics approach, it needs to follow the essential procedures described below (Sterman, 2000 Complex problems could not be solved by using a simple method with a single cause. Thus, the system providing a basis to understand multiple causes of problems in a system framework is highly needed (Bastan, Sisi, & Nikoonezhad, 2016;Reinker & Gralla, 2018). However, the researchers have not investigated yet so far about the system dynamics in Gunungkidul Minapolitan based on its potential dryland catfish aquabusiness.…”

Dry land-based catfish fishery is one of the promising rural aquabusiness in Gunungkidul, Yogyakarta. There are several problems in this business, for example, supply-demand balancing, calculation accuracy of production capacity, and equitable profit distribution to each stakeholder. This research aimed to design a closed-loop supply chain of dry-land catfish industrial-fishery model by employing the system dynamics approach. Powesim Studio 7 coupled MINITAB 14 was applied to measure the robustness of the supply chain management system, to predict optimum production capacity, and to balance profit distribution. A financial analysis was also performed to determine business feasibility. Three scenarios of price were created by considering the predicted trend of catfish consumption and formulated three alternative prices by appraising the juvenile fish production, aquaculture practices, local feedstock manufactured by farmers, and fish-by products distributed by small-enterprises. Those consideration units were constructed of four observed models. The highest profit to stakeholder was obtained by scenario III that was directed to increase the juvenile fish price to Rp 240/fish, consumption-sized fish at the price of Rp 18,000/kg, fish-by product at the price of Rp 150,000/kg, and local feed at the price of Rp 9,000/kg. According to financial analysis, the four subsystems in dry land-based catfish aquabusiness were all feasible by BCR>1; PP was 5-9 years, NPV>0, PI>1, and IRR>15%/year. The implementation of the system required synergetic action among policymakers, farmer cooperative, and local innovation centers.
