The integration of carbon captured by forest ecosystems into forest management planning models has become increasingly more important, particularly in the areas of climate change, land use, and sustainable forest management. The main objective of this work is to develop a multiple-use forest management planning model that focuses on the interactions of net carbon sequestration and timber production opportunities in a forest ecosystem including forest openings. The linear programming model is used to develop various forest management scenarios for a forest that yields timber and carbon objectives. The results of forest management planning scenarios showed that increased net carbon sequestration can be attained at a significant cost in terms of forgone timber harvest and financial returns. Results also showed that reforestation of forest openings and long-term protection of forest ecosystems provides high biomass and carbon storage over the planning horizon.

This article presents evaluation of effi ciency of the production scale of Polish milk processing companies in 1999–2010 performed basing on non-parametric methods. The non-parametric approach stemmed from linear programming method known as the Data Envelopment Analysis (DEA) method. The study involving a sample of 743 objects revealed increasing returns to scale observable in the Polish dairy sector. Further concentration of the dairy sector in Poland should lead to the better results of dairies. This analysis confi rmed earlier conclusions of relevant literature.

With the Water Framework Directive (WFD), the European Union has established a legal framework for the protection of all aquatic ecological systems, including groundwater. This directive may have advantages for the water regime in ecologically sensitive areas but may also bring some economic disadvantages for farmers. The economic implications of the WFD for irrigated agriculture with regard to various scenarios and the implementation of alternative water policy measures are analysed. The results show that demand for irrigation water, farmers’ reactions with regard to operational and strategic decisions and income effects strongly depend on the water policy measures implemented.
