Abstract
One of the main impediments to a correct forest management has to do with serious gaps in public participation and stakeholders’ involvement in drawing up and carrying out public policies. The Natura 2000 Montemuro Mountain Site is paradigmatic of this situation. By looking at a set of interviews conducted to several entities with ties to the forest sector in that territory, this paper identifies their perception as regards the forest in Montemuro Mountain. Results show both the lack of participation and communication among the various stakeholders and the absenteeism of many forest owners as important factors conditioning forest management.

Abstract

The purpose of the paper is investigating relations between human development and economic growth, with a view to identifying major policies and prioritizing of them across Iranian provinces. In order to, human development index (HDI) between Iranian provinces over 1996, 2006 and 2001 have been created, and then with using the Co-integration and Granger causality technique have been measured long term relationships between economic growth and HDI. The findings suggest that although still inequality remains but the quality of life also has risen and these improvements seems have significant impact on long term economic growth. Also we find that HDI is positively influenced by Per capita GDP and if we want high levels of quality of life, we must dedicate a special consideration to economic growth in regional Policies across provinces.

Abstract
The aim of this contribution is to apply methods from optimal control theory to the mathematical modeling of biological pest control. We formulate a pest control strategy for nonlinear Kolmogorov system of n interacting populations by introducing natural enemies as a control function. The sufficient conditions for existence of an optimal feedback control function are based on the fact, that the steady-state solution of the Hamilton-Jacobi-Bellman partial differential equation is a Lyapunov function guaranteeing stability and optimality. We apply those general results to the Lotka-Volterra system with a logistic rate of increase of the prey population and Holling’s second type functional response of the predator population, to illustrate biological control of pest mite in stored grain Acarus siro by predatory mite Cheyletus eruditus.
