In Slovenia, the Natura 2000 network covers 35.5% of its territory or 286 areas, encompassing 10 forest habitat types. The majority of indicators for the assessment of the conservation status and changes of forest habitat types are to be estimated within the forest management planning framework. In this paper, a hierarchical concept of forest habitat types monitoring in Pohorje Mts (810 km2) was examined and presented, based on landscape structure and position of habitat types in this structure.

Land-use and land-cover changes are driving unprecedented changes in ecosystems and environmental processes at different scales. This study was aimed at identifying the potential land-use drivers in the Jedeb catchment of the Abbay basin by combining statistical analysis, field investigation and remote sensing. To do so, a land-use change model was calibrated and evaluated using the SITE (SImulation of Terrestrial Environment) modelling framework.

This paper presents data about forestry and reforestation in the Republic of Macedonia. The country is characterized with great diversity of natural conditions and rich floral and faunal biodiversity Forests in Macedonia cover 38% of its territory. About 71% represent coppiced and degraded and 29% tall forests. Historical, social and natural conditions caused gradual deforestation, forest and land degradation. Foundations of artificial afforestation were laid in the first decade of XX century.

Recent research on payments for environmental services (PES) has observed that high transaction costs (TCs) are incurred through the implementation of PES schemes and farmer participation. TCs incurred by households are considered to be an obstacle to the participation in and efficiency of PES policies. This study aims to understand transactions related to previous forest plantation programmes and to estimate the actual TCs incurred by farmers who participated in these programmes in a mountainous area of northwestern Vietnam.

Agricultural landscapes presently cover about 46 % of earth terrestrial surface. This cultivated area is decreasing, whereas the global food demand is projected to increase up to 70 % in 2050. The intensification of agriculture is not a solution to this food issue because intensive agriculture has often resulted in pollution and loss of biodiversity. On the other hand, mechanistic models with optimization algorithms can be used to design alternative land uses for sustainable agriculture.

The lowlands of the Caribbean slope of northern Costa Rica constitute one of the priority hotspots for biodiversity conservation in Mesoamerica.Nevertheless, the landscape has undergone a process of strong fragmentation that threatens its connectivity between protected areas in Costa Rica and southeastern Nicaragua.

We review seven certification systems for verifying carbon trading from forestry and other land uses, and evaluate evidence of their effectiveness in generating social and environmental co-benefits. Published research on non-carbon co-benefits was located by searching the three principal bibliographic databases in this area of science: CABI, ISI Web of Science Core Collection and SCOPUS. We included studies published in English from 2000 to 2016. Our searches yielded 679 studies after duplicates were removed.

Vietnam has pilot-tested a payment for forest environmental services (PFES) program in an effort to restore and protect forest areas, some of which have been severely degraded by the excessive cutting of trees by small-scale farmers planting annual crops on steep, sloping lands. The pilot program implemented in southern Vietnam seems to be successful, yet the program in northern Vietnam has not produced the desired rates of planting and maintaining forest areas.
