    Afforestation of former agricultural lands is a common practice in several countries. This is beneficial for avoiding diseases carry-over from previous forest generations and to expand forest areas. However, several biotic and abiotic risks have been reported in such stands, including a higher risk of Heterobasidion root rot after thinning. Therefore, this study investigates the spread of Heterobasidion root rot in three Picea abies (L.) Karst. plantations in Latvia established on former pasture and meadow lands and subjected to forest management practices.

    Effective management decisions regarding greenhouse gas (GHG) emissions may be hampered by the lack of scientific tools for modeling future land use change. This study addresses methodological principles for land use development scenario modeling assumed for use in processes of GHG accounting and management. Associated land use policy implications in Lithuania are also discussed.

    In this paper we show how cost-benefit analysis can be used as a decision support mechanism for the location of new (urban) forest land, starting from the multifunctional role of these new forests. We start with a simple presentation of the cost-benefit analysis (CBA) technique. Key features of this evaluation technique are that (i) all - both positive and negative - impacts for all relevant parties (i.e. not only the project promoter) are taken into account and (ii) evaluation occurs on the basis of monetary values.

    Solution of ecological problems is an urgent and extremely important task at the present stage of social economic development of Ukraine. Unreasonably high degree of economic (mostly agricultural) reclaiming of area causes spreading and intensification of degradation processes in ecosystems. Conservation of lands, including the one carried out by means of foresting of degraded lands, is the principal way to renature environment. The article concerns an issue of land conservation in the context of ecosystem services of forests.

    Agricultural transport roads play an important role not only from the point of view of individual farm holdings, but also the general development of rural areas. Roads constitute an element of the technical infrastructure indispensable for communication and transport; they play a role in shaping the rural landscape, and the routes they follow affect the forms and size of agricultural land and forest areas found within the area covered by a given road system. The existing public road network does not always provide access to all fields.

    The article presents the Lithuanian forest land change in the period of more than a hundred years. The causes leading to forest land use change are analysed in the article. The beginning of forestry in Lithuania can be traced back to Sigismund Augustus times starting from 1557, when Wallach reform was launched. However, over time forest land and its use evolved for a variety of political, social and economic factors. In 1795 the state-owned forests in Lithuania amounted to 35% of the total area of forests; other forests were owned by landlords, churches and kulak farms.
