The history of the forests in canton Geneva, having led to these being disconnected from productive functions, provides a symptomatic demonstration that the services provided by the forest eco-system are common goods. Having no hope of financial returns in the near future and faced with increasing social demands, the state has invested in the purchase of forest land, financed projects for forest regeneration and improvement of biological diversity and developed infrastructures for visitors. In doing this the state as a public body takes on the provision of services in the public interest. But the further funding for this and for expenses for the private forests, which must be taken into account, are not secured for the future.

 This paper reviews and analyses the present status of private forests and tenure administration in light of existing legal, policy, and regulatory frameworks in Nepal. Additionally, the present status of private forests, as well as the scenarios of timber harvesting, transportation, marketing, and their administration are thoroughly revised. Provisions regarding forests and trees on private land and their basis are examined and implications are articulated for potential policy improvements for enhanced tenure security. It is shown that robust national-level policies and legal frameworks exist, and that there is an increasing trend of timber flows to markets from private forests over the past five years. However, there is still skepticism, mistrust and fear amongst private forest owners, saw millers, and forest administration that prevents the full use of the bundle of rights that legal and policy provisions have promised. An unusually slow pace of private forest registration, lengthy and multi stage processes for obtaining harvesting and transportation permits, and official bans on important commercial species, among others, are found to be the factors that most hinder the private forest owners’ and tree growers’ interests, and their rights and obligations with respect to the management and use of their private forest resources. It is concluded that a simplified permitting process along with programmatic support would promote and help to grow private forestry and that Nepal’s experience and lessons learned from community forest implementation would be a great asset to move towards this end. Connecting community forest user groups for organised and cooperative action, and mobilising their institutional strength and accumulated funds for pro-farmer technical and regulatory support would allow farmers to intensify tree plantations and forest management. Further steps are required to convince policymakers and secure necessary budgetary support to this end..

Predicting and allocating water resources have become important tasks in water resource management. System dynamics and optimal planning models are widely applied to solve individual problems, but are seldom combined in studies. In this work, we developed a framework involving a system dynamics-multiple objective optimization (SD-MOO) model, which integrated the functions of simulation, policy control, and water allocation, and applied it to a case study of water management in Jiaxing, China to demonstrate the modeling. The predicted results of the case study showed that water shortage would not occur at a high-inflow level during 2018–2035 but would appear at mid- and low-inflow levels in 2025 and 2022, respectively. After we made dynamic adjustments to water use efficiency, economic growth, population growth, and water resource utilization, the predicted water shortage rates decreased by approximately 69–70% at the mid- and low-inflow levels in 2025 and 2035 compared to the scenarios without any adjustment strategies. Water allocation schemes obtained from the “prediction + dynamic regulation + optimization” framework were competitive in terms of social, economic and environmental benefits and flexibly satisfied the water demands. The case study demonstrated that the SD-MOO model framework could be an effective tool in achieving sustainable water resource management.
