Net pasture production has been monitored over time on an on-going Pinus radiata-pasture agroforestry experiment located at Carngham, Victoria. Established in 1983 by thinning a 2-year-old plantation, the study contains five treatments (systems): open pasture (no trees), 60 trees/ha, 200 trees/ha wide-spaced, 200 trees/ha 5-row belt and 1360 trees/ha. Net pasture production was only weakly affected by the proximity of trees in the 60 trees/ha and 200 trees/ha wide-spaced systems. However, in the 200 trees/ha 5-row belt system, pasture production was often significantly less within the tree zone and at 1.5 m from the tree edge compared with production at 10.5 m from the tree edge. While there was a trend for greater pasture production at 10.5 m and 18 m from the tree line than occurred in the open pasture system, the width of pasture adjacent to the 5-row belts was too narrow (36 m) to demonstrate any shelter benefit on pasture production. From 1990 to 1992, pasture production (kg ha-1) for each system was similar, although production tended to decrease with increasing tree stocking. Following the cessation of pruning (1992), pasture production was significantly reduced by increased tree stocking, such that pasture production in the 200 trees/ha wide-spaced and 200 trees/ha 5-row belt systems was 60% and 69% and 23% and 67% of open pasture in 1993 and 1994 respectively.

Liveweight and greasy wool production data from young wethers were collected for the period autumn to early summer for the years 1986 to 1994 from an on-going Pinus radiata-pasture project at Carngham, Victoria. A plantation established in 1981 on a grazing property was thinned in 1983 to give trees spaced at: (i) no trees (a grazing control), (ii) 8 mx 12 m, (iii) 4 mx9 m, (iv) 4 mx3 m in a 5-row belt then a 10-row pasture gap, and (v) 2 mx3 m (original spacing). By 1989 the density of trees in these systems was slightly reduced by windthrow, animal damage and thinning to (ii) 60 trees/ha, (iii) 200 trees/ha wide-spaced, (iv) 200 trees/ha 5-row belt and (v) 1360 trees/ha. All trees in systems (ii), (iii) and (iv) had been pruned to 6 m by late 1992. The sheep stocking policy was initially based on a set 10 sheep ha-1. Since 1991 the stocking rate has been varied yearly in an attempt to maintain similar production per sheep. The pastures were re-sown in 1989 with perennial rye-grass and subterranean clover cultivars. Since 1991, wool production per ha from the 200 trees/ha wide-spaced system has been consistently less than in systems (i), (ii) and (iv). Wool production among systems differed significantly since 1992. Expressed as a percentage of wool production achieved on open pasture, the relative values for the agroforestry systems from 1990 to 1994 as follows.

These experiments evaluated in northeastern Victoria the factors affecting the severity of browsing damage to eucalypts by sheep. We aimed to develop management options for integrating sheep grazing in agroforestry systems. One-year-old tree seedlings were planted into annual pasture and grazed at high stocking rates (44 sheep/ha) for up to 1 week when the pasture was abundant. In experiments 1 and 2, crossbred weaners almost totally defoliated Eucalyptus camaldulensis (river red gum) seedlings after 96 h grazing; damage from older Merino wethers was minimal. Of the 4 eucalypt species tested for relative acceptability or palatability to crossbred weaners, E. camaldulensis was the most heavily browsed and E. globulus spp. bicostata (southern blue gum), least. The height of the pasture immediately surrounding the seedlings, and therefore visibility of the seedling to the sheep, did not affect browsing extent. In experiment 3, potential repellents were applied either on the ground around E. camaldulensis seedlings or sprinkled on the foliage. Six repellants provided short-term protection from crossbred weaner sheep; Replex 1 and 3, and egg and paint were the most effective. After 4 days grazing, seedlings treated with Replex 3 had sustained 24% mean browsing damage compared with 90% for the control.

Use of saline lands for agroforestry relies primarily on plant species that have the trait of salinity tolerance, and also other economic and agronomic benefits. The selection of species, however, also needs to consider other key factors such as compatibility with existing flora, and potential for environmental benefits such as improved soil fertility or lowering of the water table in the case of dryland salinity. The testing of candidate species in particular environments needs substantial investments of costs and time. In this paper, a novel approach is presented for the rapid identification of potentially salt tolerant Acacia species, based on molecular phylogenetic analysis. The approach has been applied to four species groups, Acacia pendula, A. salicina, A. victoriae and A. stenophylla. The nuclear-encoded ribosomal DNA internal and external transcribed spacer (ITS and ETS) regions were used as markers, and phylogenetic analyses undertaken to identify closely related species that may share the salt tolerance traits. Such a methodology could be used to more rapidly identify candidate native species for agroforestry in salinity-affected regions and for preventing further expansion of salinity, thus assisting in biodiversity conservation.

En el Fundo LUFE I, ubicado en el Caserío La Victoria, distrito de Campo Verde en Pucallpa se evaluó el crecimiento, productividad y almacenamiento de carbono del componente forestal en dos parcelas contiguas (A y B) con un mismo sistema agroforestal basado en plantas de cacao de tres y cuatro años de edad. Se midieron variables cualitativas (cruzamiento de ramas, rectitud de tronco, forma de fuste, calidad de fuste y raleo) y cuantitativas (altura total, altura comercial, DAP y cantidad de trozas comerciales) de todos los árboles en ambas parcelas (Guazuma crinita Lam., Calycophyllum spruceanum (Benth.) K.Schum. and Swietenia macrophilla King). La parcela A presentó un mejor performance de las variables cualitativas y cuantitativas con el 63% de los árboles con fuste recto, a diferencia del 57% de la parcela B, en calidad de fuste 70% bueno y 54% malo. Ninguna parcela presentó raleo ni cruzamiento de ramas, y el 100% de ambas parcelas tenía un estado fitosanitario excelente, la parcela A presentó mayor promedio de DAP, volumen comercial, IMA, altura total, altura comercial y área basal asimismo con un almacenamiento de carbono de 4. 69 t/c/ha en comparación a 2.10 t/c/ha de la parcela B, y con 253 trozas comerciales a diferencia de 114 trozas para la parcela B.

During the years the awareness of gender issues has increased in the international arena and the importance of including gender aspects in development projects has been emphasised. This Master’s thesis is based on a case study of the VI Agroforestry Project (VIAFP) in Uganda and is one of the two subprojects of the study Sustainable development around the Lake Victoria basin, with the purpose to investigate the importance of local anchoring and active participation in the work towards sustainable development. The aim of this subproject is to investigate how gender roles among men and women in Kalisizo zone, in the Masaka and Rakai districts, in Uganda, affect the VI Agroforestry Project and if the project in return affects the gender roles. The study is primarily based on interviews with farmers involved in the VIAFP activities in Kalisizo zone and shows that the project and the gender roles affect each other more or less in both ways. The women are somewhat more active in both farming and the activities connected with the household, and therefore also more engaged in the project activities and meetings. However, the gender roles have changed in the way that men have increased their interest in farming activities since they joined the VI Agroforestry Project. Both men and women involved in the VIAFP activities have more work on their farm than before they joined the project, but it seems as if they think it is worth the extra effort to gain more in the end. However, the project has to consider the fact that women often have a bigger workload to start with. It is important for the VIAFP to adjust the activities and the feedback to different wishes and needs within the communities so that everyone feels they gain from the project activities, and also so that everyone who wants to participate at different activities have the opportunity to do so. Since the majority of the staff are Ugandans the ways of implying values from the North into the communities are less than if this had not been the case. The study is published in two versions, both as a Master's thesis for the Environmental Science Programme, Linköping University and as a Minor Field Study for Sida. The differences between the versions are only editorial.
