Forest road and public purpose investment

Optimal Forest Road Density Based on Skidding and Road Construction Costs in Iranian Caspian Forests

Information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of Caspian forests. Skidding and road construction costs are expensive forest operations. Determining the optimum forest road network density is one of the most important factors in sustainable forest management. Logging me...

Forest road design combining common design techniques and GIS (Case Study: 2nd series of Liresar Forest)

Nowadays, it is necessary to apply modern techniques for the design of road networks, especially roads passing through ecosystems such as forests, in order to reduce operating costs, prevent further degradation of the environment, increase road efficiency and achieve sustainable development goals. In this paper, a new way of designing the road is presented. New design method has the ability to ...

Forest Road Prism

The effectiveness of four road turn–out ditch treatments (vegetation, rip–rap, sediment fences, and settling basins) in reducing sediment export to the forest floor was evaluated. These four runoff control methods are commonly prescribed to control forest road runoff and sediments. The study utilized runoff samplers, runoff diversion walls, sediment filter bags, and erosion stakes to evaluate r...

Public investment as commitment

Should public assets such as infrastructure, education, and the environment earn the same return as private investments? We consider if time-inconsistent decisionmakers can gain from institutions that enforce cost-benefit rules on large projects that influence the economy as a whole. Long-term public investments provide commitment to current preferences, leading to investment biases in such ass...
