“…The response is higher if the sludge is applied early when initial temperatures allow the pasture to use the nutrients but lower when the initial temperature does not allow pasture growth because of leaching (Peyraud et al 2004). In the last case, the presence of a tree with deep roots makes possible the use of leached nutrients and therefore reduces nitrate contamination (Nair et al 2008).…”

Tree-understory competition is one of the most important aspects that control tree growth after reforestation. The relationship between trees and the understory can be modified by improving acidic soils with lime and by fertilisation. This experiment aims to evaluate the effect of soil improvements on the pasture-tree relationship by liming and fertilisation on different dates in a Pinus radiata-reforested area. Both lime and sewage sludge improved soil fertility by increasing Ca and reducing Al in the soil.

“…The positive interaction of trees and crops facing pests, diseases or weather events is a feature well documented in literature (see Torquebiau 2000;van der Werf et al 2007;Nair et al 2008), and among agroforestry systems, shade coffee is acknowledged for its advantages in this regard (Gordon et al 2007;López-Gómez et al 2008). The capacity to adjust to climatic changes and fluctuations in weather and in insect populations and to sustain ES is more limited in homogeneous landscapes when compared to rich biodiversity areas with greater capabilities for environmental response and functional diversity (Chapin et al 2010).…”

Avoiding the loss of shade coffee plantations: how to derive conservation payments for risk-averse land-users

et al. 2012

We usually have only limited knowledge about the economic consequences of land-use decisions, thus they are uncertain. We analyze the implications of this uncertainty on conservation payments (CP) to preserve wildlife-friendly shade coffee production in southwest Ecuador, when conversion to maize is the most profitable alternative. Our objective is twofold: First, we analyze the consequences of applying Stochastic Dominance (SD) to derive CP, an approach making only minimal assumptions about the preferences of farmers. Second, we investigate the effects of land-use diversification to reduce CP by allowing for shade coffee on part of a landholding, and maize production on what remains. CP derived by SD turned out to be at least twice the amount calculated by an alternative method which maximizes a concave utility function-US$ 166 to US$ 294 ha -1 year -1 instead of US$ 86 ha -1 year -1 . Given this result, we doubt that the assumptions underlying SD are reasonable for farmers, who are known to be riskaverse. Allowing for land-use diversification has a significant impact on CP. The optimal portfolio share of shade coffee is 27 % and for maize 73 % for moderately risk-averse farmers-without any CP. A larger share of shade coffee is preferable for strongly risk-averse farmers-51 and 49 % maize. The amount of CP necessary to encourage the expansion of shade coffee to 75 % is US$ 40 ha -1 year -1 (for moderately risk-averse) and US$ 19 ha -1 year -1 (for strongly risk-averse farmers). Stimulating diversification may thus help to significantly reduce CP necessary to preserve less profitable agroforestry options.

“…Spatial and temporal heterogeneity, perennialism, and the structural and functional diversity are the ecological properties that are fundamental to such systems (Nair et al, 2008). Comparisons are usually made with natural forested or agroecosystems in terms of the extent to which these properties are maintained in AFS.…”

Managed Multi-strata Tree + Crop Systems: An Agroecological Marvel

Today, when the emphasis on single-species production systems that is cardinal to agricultural and forestry programs the world over has resulted in serious ecosystem imbalances, the virtues of the time-tested practice of growing different species together as in managed Multi-strata Tree + Crop (MTC) systems deserve serious attention. The coconut-palm-based multispecies systems in tropical homegardens and shaded perennial systems are just two such systems. A fundamental ecological principle of these systems is niche complementarity, which implies that systems that are structurally and functionally more complex than crop-or tree monocultures result in greater efficiency of resource (nutrients, light, and water) capture and utilization. Others include spatial and temporal heterogeneity, perennialism, and structural and functional diversity. Unexplored or under-exploited areas of benefits of MTC systems include their ecosystem services such as carbon storage, climate regulation, and biodiversity conservation. These multispecies integrated systems indeed represent an agroecological marvel, the principles of which could be utilized in the design of sustainable as well as productive agroecosystems. Environmental and ecological specificity of MTC systems, however, is a unique feature that restricts their comparison with other land-use systems and extrapolation of the management features used in one location to another.
