Abstract:
AbstractGrowth characteristics and fertility variations were evaluated at four natural stands of tropical arid zone species,A. leucophloeain southern India. Three stands (TNL 1, TNL 2 and PDM) were situated in dry upland regions while one stand (RKP) was at waterlogged site. The tree height and girth at breast height did not vary between stands in two years. Fertility variation (sibling coefficient, ψ) was estimated based on flowering abundance and fruit set collected for two consecutive years. Fruit production per tree was generally lower in the RKP stand than the other three stands. No year-

The paper analyses stand structure and production on two experimental forest stand series of mature pure and mixed Scots pine stands, growing on natural Scots pine sites in the Czech Republic. Sessile oak was the main admixed species. In mixed stands, Scots pine constituted the dominant level of the stand, admixed species grew mostly as subdominants. Admixture increased stand densities and aboveground biomass production compared to pure stands. Sessile oak with the 20–30% number share within the Scots pine stand led to an increase of the Scots pine tree dimensions and mean stem merchantable wo

Wildfires are currently considered the major threat to forests in Mediterranean countries. It has been implied that a large percentage of arson-caused fires in Spain are connected with the extensive reforestation programs implemented between 1940 and 1970.

Therefore, the goal of this study was to analyze occurrences and model the influence of forest stand origin (artificial or not) on the development of wildfires in peninsular Spain.

Windthrow is a dominant natural disturbance in the boreal forest of eastern Canada.

Landscape scale corresponded to three areas of about 5000 ha. Stand scale was the finest scale of analysis and corresponded to each

Abstract:
Decarbonizing industries could significantly increase electricity demand, necessitating strategic grid expansion. This study evaluates the impact of decarbonizing the Pulp and Paper Sector under four 2050 scenarios: carbon capture, biomass-based, direct electrification, and indirect electrification. A bottom-up approach is employed to estimate 2020 final energy demand by heat grade and subsector. Both final and primary energy demand systems are modeled, accounting for the efficiencies of end-use technologies and primary energy transformation processes. The analysis compares primary renewable e

Abstract:
A brief overview of mineral extraction fields in the Kabardino-Balkar Republic is given. Taking into account the forest-growing conditions of the substrate types, the directions for creating forest plantations are proposed. Soil mixtures in the research region are divided into 3 main groups according to the degree of suitability for biological reclamation: unsuitable, requiring long – term reclamation, unsuitable, becomes suitable after improving their properties, suitable-potentially fertile and fertile soils. In order to increase the efficiency of reproduction of anthropogenic landscapes, me

Abstract:
Every year forests are becoming more and more recognized as a global factor in nature conservation. Recreational activities aimed at exploiting the natural environment have led to the degradation of natural landscapes in many regions of the planet. The article examines the current state of clean pine plantations in Bobrovsky district, Voronezh region, subject to recreational stress.

Abstract:
The paper analyzes the change in the entropy production of an open thermodynamic forest ecosystem, in which processes associated with the entry of a negative entropy flow into it can be realized. Using the example of computer modeling of the dynamics of effective specific entropy production for a single-pedigree stand, it is shown for the first time that the specific entropy production as a function of time corresponds to the Prigogine-Glensdorf principle, and the time to reach a stationary state coincides with experimental values from forestry tables.

Abstract:
Today, the problem of forest conservation and restoration in the context of progressive climate change and increasing anthropogenic pressure remains relevant. Our works have repeatedly noted that the conservation of the planet's biodiversity continues to be a topical issue, as it is a problem of our time. The development of methods and ways to restore forest communities' stands continues to be a priority in forestry, as forest resources are renewable, but require a fairly long period for restoration. Observations, assessment and control by environmental authorities are necessary, since in a ch

Abstract:
Public-private collaboration in productive development policy in Costa Rica frequently takes the form of policy co-governance: an autonomous institution in charge of policy for a particular economic sector is created, with a board of directors comprising representatives from both the public and the private sectors, often with the public sector in a minority position. This paper analyzes five cases of co-governance: tourism, fisheries, rice, coffee, and the attraction of foreign direct investment (FDI).
