“…The cash flow of silvopastures is also much improved compared to forestry operations alone due to the annual returns of the livestock operation (Grado et al 2001). Overall, silvopastures may be more or less profitable than conventional agricultural and silvicultural practices (Clason 1999;Husak and Grado 2002;Grado et al 2001;Stainback and Alavalapati 2004;Bruck et al 2019). It is clear that silvopasture practices are very productive, but the profitability of these practices will depend on the valuation of silvicultural and agricultural products and inputs required to successfully maintain these high levels of production.…”

Over-yielding in an intercropping system occurs when the productivity of the intercrop exceeds the overall productivity of the systems managed in segregation. The objective of this systematic review was to calculate the over-yielding of silvopastures compared to open pastures and forests, timber plantations, or orchards managed separately. A literature search was completed for comparisons of the productivity of these practices in temperate regions. Data collected from these studies included mean yields of timber or non-timber forest products, forages, and livestock, as well as the characteristics of the study site. Silvopasture practices improve the productivity of land typically managed separately for pasture or trees by 42–55%, depending on whether the productivity of the pastures is measured by livestock or forage output, respectively. In most cases, over-yielding occurred despite a reduction in individual forage, livestock, or tree productivity in the silvopastures. Calculating confidence intervals around these means was not feasible because standard errors were largely not reported or available. Some assumptions were made about the actual productivity of timber or non-timber forest products. This work illustrates the significant level of over-yielding that may be achieved by integrating trees, forages, and livestock into a single production system.

“…The incorporation of trees in pastures could enhance P storage in the soil-plant system (Nair and Graetz 2004;Nair and Kalmbacher 2004;Nair et al 2007). Silvopasture, the intentional combination of trees, forage plants and livestock into an integrated, intensively managed system (Nair 1993;Garrett et al 2000;) is potentially a promising land-use system to enhance the economic returns of forestry operations (Clason and Sharrow 2000;Grado et al 2001;Stainback and Alavalapati 2004).…”

Silvopasture for reducing phosphorus loss from subtropical sandy soils

Phosphorus (P) losses from sandy soils that are predominant in the 1.4 million ha of pastureland in Florida are a major cause of water pollution. We hypothesized that soil P loss would be lower from silvopastoral systems than from treeless pastures because soil P removal by a combined stand of trees and pasture would be more than that of treeless pasture. Four slash pine (Pinus elliottii Engelm.) + bahiagrass (Paspalum notatum Flüggé) silvopastoral systems located in Alachua, Suwannee, Manatee, and Osceola counties in Florida were selected for the study. The former two sites are on Ultisols, and the latter two on Spodosols. Soil samples were collected at different depth increments. Soil P storage capacity (SPSC), the maximum amount of P that can be safely applied to a soil before it becomes an environmental concern, was calculated. Water-soluble P concentrations in the 0-5 cm soil layer ranged from 4 to 11 mg kg −1 for the silvopasture sites and 10 to 23 mg kg −1 in the treeless pasture sites, with higher P concentrations in the treeless pasture at each location. Total SPSC in the upper 1 m depth ranged from 342 to 657 kg ha −1 in the silvopasture sites and −60 to 926 kg ha −1 in the treeless pasture sites (a negative value indicates that the soil is a P source). The results suggest that P buildup within the soil profile and therefore the chances for loss of P from soil to water bodies were less from silvopastures than from treeless pastures. Thus, silvopasture systems can be expected to provide greater environmental service in regard to water quality protection compared to treeless pastures under comparable ecological settings

“…This increases the land use efficiency and enables them to manage two production systems on the same piece of land, thereby increasing the income from the same land unit (White 2005;Stainback et al 2004;Vishwanatham et al 1999). The incorporation of trees in to the pastureland also reduces the foraging energy of livestock (White 2005), which altogether increase their productivity.…”

A study was conducted in central Ethiopian highland in 2008 to investigate the consumption of house construction wood, the tree species preference for construction wood and the forthcoming conditions of this forest product and possible strategies for future availability. Twenty-four iron-roofed houses and twenty-eight thatch-roofed houses belonging to thirty-six farm households were investigated for types, volumes and sources of construction wood used. It was found that an average farmhouse with a floor space of 57 m 2 consumed about 13.7 m 3 of wood. Both floor space and wood consumptions vary with house types. An average iron-roofed house with floor space of 51.9 m 2 consumed 16.8 m 3 of wood and an average thatch-roofed house with mean floor space of 28.6 m² consumed 3.2 m³ of wood. Family size and floor space were the major factors influencing construction wood consumption. An average living house was composed of woods of 39.3% Juniperus procera, 5.6%Cupressus lusitanica, 29.2% Eucalyptus globulus and 26% Eucalyptus camaldulensis. The wood volume from the first two species and half that of the third species were obtained from state forest which is currently banned from any construction wood extraction and hence there is a shortage of around 59.5% of woods. We suggest the promotion of various tree planting approaches to increase the wood supply and the use of alternative local materials like soil bricks for house construction.
