  • Simulating effects of precipitation and initial planting density on
           population size of Mongolian pine in the Horqin Sandy Land, China
    • Authors: Yi Tang; Xu Li
      Pages: 1 - 9
      Abstract: Abstract Sand dunes in China are widely re-vegetated with Mongolian pine (Pinus sylvestris var. mongolica). However, the effects of precipitation and planting density on population dynamics of this tree species are not well known. We established a system dynamics (SD) model for Mongolian pine to explore the effects of precipitation and initial planting density on population dynamics. This study applied the SD model in simulating the dynamics of a plant population with random environmental factors. The results in this study revealed that the SD model performed well in reflecting the dynamics of Mongolian pine population in the Horqin Sandy Land (ARE < 0.13, MARE = 0.048). Population size fluctuated in the range of 1150–1350 individuals ha−1 under mean annual precipitation of 500 mm and planting density of 10,000 individuals ha−1, suggesting that this range was the fittest density of Mongolian pine population at that precipitation level. Population size varied with precipitation, indicating that water supply played an important role in determining the dynamics of Mongolian pine population. Initial plantation density did not influence population size in scenarios with high precipitation but it influenced population size under low precipitation. This suggested that initial plantation density was more important under low than under high water supply used to support the development of Mongolian pine population. These results are important for formulating guiding principles for the management of Mongolian pine populations in the Horqin Sandy Land.

  • Traditional management affects the phenotypic diversity of fruits with
           economic and cultural importance in the Brazilian Savanna
    • Authors: José Ribamar Sousa Júnior; Rosane Garcia Collevatti; Ernani Machado Freitas Lins Neto; Nivaldo Peroni; Ulysses Paulino Albuquerque
      Pages: 11 - 21
      Abstract: Abstract The management of plant populations may cause phenotypic changes in the characteristics of a plant that is targeted by human selection over time, which can therefore lead to the domestication process. Studies about this approach have shown that managed plant populations have the most interesting features for use by human populations because they have more productive plants and larger fruits. To evaluate this effect, the traditional management of Caryocar coriaceum Wittm (pequi) in the Chapada do Araripe region of Northeast Brazil was studied by using a morphometric and ethnobotanical approach. A morphometric analysis of the fruits was conducted, during which the plants were recorded to the following three different management regimes: cultivation, in situ management (collection) and incipient management (the tolerance and protection of individuals). To test the hypothesis that people perceive natural morphological variations in the fruits, local people perception was assessed through different methods. To assess the possible influence of management regimes on fruit morphology, 40 reproductive individuals cultivated, 40 managed in situ and 36 individuals under incipient management were randomly selected, and 20 fruits of each were collected for the morphometric analyses. The fruits from individuals grown under the cultivation system were significantly different from the individuals who were managed in situ and from those under incipient management. The perception study showed that local people perceive great morphological diversity among the study populations, which was consistent with the findings of the morphometric analyses. Based on these results, it could be said that C. coriaceum is in the early stage of the domestication process.

  • Honey bees are essential for pollination of Vitellaria paradoxa subsp.
           paradoxa (Sapotaceae) in Burkina Faso
    • Authors: Kristin Marie Lassen; Lene Rostgaard Nielsen; Djingdia Lompo; Yoko Luise Dupont; Erik Dahl Kjær
      Pages: 23 - 34
      Abstract: Abstract Shea (Vitellaria paradoxa) is an important fruit tree in West African parklands, and its successful pollination is a requirement for fruit production. Size-based pollinator exclusion experiments combined with visual observations showed that presence of honey bees (Apis mellifera jemenitica) was important for pollination and thereby the production of fruits and seeds. Smaller insects, mainly species of stingless bees (Hypotrigona spp. and Liotrigona cf. bottegoi) and solitary bees (Compsomelissa borneri) could partly compensate pollination in absence of honey bees, but fertilisation and fruit yield was reduced. A positive correlation between fertilisation percentage and number of honey bee colonies within radii of 900 and 1000 m was observed. The percentage of fertilisation and number of mature fruits per fascicle were higher in trees with colonies of stingless bees in the trunk when honey bees were excluded by bagging. We conclude that local beekeeping with honey bees and stingless bees is likely to have a positive influence on fruit production of shea trees in the farmed West African parklands, which speaks in favour of a pollinator friendly environment.

  • Microbial communities and residues in robinia- and poplar-based

      Abstract: Abstract Organic farming and agroforestry are considered as sustainable alternative agricultural practices for intensive agriculture. In a long-term field trial in Scheyern Germany, we evaluated the effects of 21-year organic farming and 4-year agroforestry (robinia and poplar) on microbial community and microbial residues. Microbial biomass and microbial community were determined by fumigation–extraction method and the analysis of phospholipid fatty acid (PLFA), respectively. Microbial residues were evaluated by the measurement of amino sugars. The results showed that organic farming had significantly positive effect on soil organic carbon (SOC) but that it tended to decrease microbial biomass C (MBC), PLFA functional guilds, muramic acid (MurN), and glucosamine (GlcN). Robinia system, however, significantly increased SOC and had the potential to enhance MBC, PLFA functional guilds especially Gram (+), but it tended to decrease MurN and GlcN, in comparison with poplar system. The hedgerow tree did not show significantly positive effect on SOC and microbial properties except the abundance of fungi and Gram (+) bacterial, after 4-year establishment period. The principal component analysis of the PLFA profile showed that in comparison with other investigated treatments, robinia system under organic farming had significantly a different microbial community structure. It also indicated tree species-specific effect on microbial community in the organic farming was stronger than that in the integrated farming. In summary, the short-term introduction of trees into an existing agricultural system will not substantially change the microbial biomass, but it has certain influence on the abundance of specific microbial groups in the hedgerow. Although organic farming did not show positive effect on overall microbial indices, we still see positive effect on SOC after 21-year organic farming and its additive effect with robinia on SOC in current study. We expect that alley-cropping agroforestry system that combines organic farming and robinia hedgerow has a great potential for sequestering SOC and developing sustainable agroecosystems with time.

  • Soil microbial responses as influenced by Jatropha plantation under
           rainfed condition in north-west India
    • Authors: Ahmad Mahmoud; S. D. Singh; K. S. Muralikrishna; H. Pathak; Namita Das Saha
      Pages: 47 - 58
      Abstract: Abstract The use of Jatropha curcas L. (Jatropha) as biofuel is currently increasing in tropical and sub-tropical regions. Jatropha species are well known for synthesizing various toxicants. However, the effects of Jatropha plantation on soil microbiota have barely been investigated. Hence, in current experiment, we had investigated the effects of Jatropha cultivation on soil microbial and biochemical properties in winter, summer and wet seasons after 9 years of plantation with different plant population densities. A nearby uncultivated area was included as the control site. Soil organic carbon was found to increase, while carbon: nitrogen ratio (C:N) decreased under Jatropha plantation as compared to control. Irrespective of seasons, mean microbial biomass C (MBC) and microbial biomass N increased under Jatropha plantation. The microbial quotient calculated as the percentage of MBC to soil organic carbon was lowest in summer and relatively constant in other two seasons. There was a significant increase in urease and dehydrogenase enzyme activities due to Jatropha plantation. The rate of decomposition of soil organic matter was faster under Jatropha cultivation compared to the control. The study revealed that irrespective of population density of Jatropha, there was improvement of soil health in terms of biochemical and microbial characteristics. These findings suggest that Jatropha can be used in the bunds of agricultural lands or in the degraded lands without any harmful effects on the soil microbial community.

  • Phenotypic plasticity of roots in mixed tree species agroforestry systems:
           review with examples from peninsular India
    • Authors: B. Mohan Kumar; Shibu Jose
      Pages: 59 - 69
      Abstract: Abstract Agroforestry entails different life forms including mixtures of trees that occupy different soil strata and exhibit a certain degree of spatial complementarity in resource use. However, rigorous experimental studies characterising root interactions in tree–tree systems are notoriously few. We present here the available empirical evidence to support the hypothesis that occurrence of two or more tree species close to one another may favour diminished lateral spread and/or deeper root penetration of the woody components and closer the tree components are located greater will be the subsoil root activity. These evidences are based on either root excavation studies in coconut-based multistorey production systems, or 32P soil injection experiments involving binary mixtures of coconut+interplanted dicot multipurpose trees (Vateria indica, Ailanthus triphysa or Grevillea robusta), and bamboo (Bambusa bambos)+teak (Tectona grandis) or Malabar white pine (V. indica). The excavation study denotes a spatially segregated root distribution pattern of the component species. Furthermore, in the coconut + dicot tree system, interplanted dicot trees absorbed considerable quantities of the radio-label applied to the palm, which declined log-linearly with distance from the palms, signifying a substantial potential for “capturing” the lower leaching nutrients, at proximal distances. Likewise, lower teak/Vateria root activity in the surface horizons and higher activity in the deeper layers, when bamboo clumps were nearby and vice versa when they were farther apart, implied that proximity of species/individuals favoured competitive downward displacement of roots. Nutrient pumping and/or current transfer of nutrients between the rhizospheres of the two associated crops are also possible. In designing sustainable agroforestry systems, it is, therefore, advantageous to mix trees with divergent root growth habits.

  • Productivity at the tree-crop interface of a young willow-grassland alley
           cropping system
    • Authors: Miriam Ehret; Rüdiger Graß; Michael Wachendorf
      Pages: 71 - 83
      Abstract: Abstract Alley cropping multi-rows of shrub willow hybrids and grassland is a promising temperate agroforestry practice for an environmentally sound provision of bioenergy feedstock. The effect of willows, aged 2–3 years, on two grassland mixtures (clover-grass, diversity oriented mixture) was determined at three positions along the tree-crop interface at a study site in Central Germany. Willows modified the incident light on understory along the interface. Biennial mean daily light integral at position south-west (SW) was 22 mol m−2 w−1, in the center of the alley 30 mol m−2 w−1 and at position north-east (NE) 26 mol m−2 w−1. Accordingly, soil temperature was lower at the positions SW and NE being adjacent to the willows. There was no clear pattern of the distribution of volumetric soil moisture content along the tree-crop interface in 15 cm depth, except that moisture content was highest in 35 cm depth at SW position in both years. In the early establishment phase, the diameter at breast height (DBH) of pooled inner willow rows (17 mm) was significantly different from pooled outer rows (21 mm). Direction had a significant influence on DBH in 2012, but not in 2013. The impact of willows on productivity of the two grassland mixtures was not confirmed until the third year after establishment. Dry matter yield was on par with those reported for single-cropped grassland adjacent to the agroforestry system. Sward composition of clover-grass changed along the tree-crop interface. Dry matter contribution of legumes was lower at the position SW. No remarkable impact of trees on quality parameters of grassland mixtures were found along the interface. Horizontal and vertical growth of the trees may modify the microclimate during the life-span of the alley cropping system consisting of willows and grassland. More research is needed on long-term monitoring of competitive, complementary and facilitative effects along the tree-crop interface.

    • Authors: Pranjal Sarmah; Snehashish Dutta; Aniruddha Sarma
      Pages: 85 - 89
      Abstract: Abstract Momordica cochinchinensis Spreng., belonging to family cucurbitaceae, is a large climber generally found under wild growing condition in the Cachar hills region of Assam, India. The fruits of this tuberous plant are supposed to possess high nutritional and medicinal properties and have been widely used in many traditional medicine practices. The present study was carried out to scientifically validate the presence of nutritional property and antioxidant activity of Momordica cochinchinensis found in this part of India. The experimental result reveals that the fruits have a high nutraceutical property and a considerable amount of antioxidative activity as the IC50 value was found to be 294.13 ± 0.46 μg/ml.

  • Diversity and abundance of arbuscular mycorrhizal fungi under different
           plant and soil properties in Sidama, southern Ethiopia
    • Authors: Beyene Dobo; Fassil Asefa; Zebene Asfaw
      Pages: 91 - 101
      Abstract: Abstract In Sidama, agroforestry represents land-use systems with deliberate management of multipurpose trees and shrubs that grow in intimate association with annual and perennial agricultural crops and/or livestock. The interaction of microbiota with the trees, shrubs and crops may make the system fertile, productive and sustainable. One of the beneficial microbiota which has symbiotic association with most of the plants in agroforestry is arbuscular mycorrhizal fungi (AMF). In November and December of 2012, root and rhizosphere soil samples of 21 plant species from nine peasant associations (PAs) (villages within districts where 300–500 families live) were collected from the agroforestry practices in Sidama of Southern Ethiopia for the determination of diversity and abundance of AMF under selected soil parameters and plant species density. Findings on the diversity of AMF based on soil properties showed that at moderate to low P and N concentrations the rate of AMF root colonization and spore density was high in comparison with the rhizosphere soils with the highest P and N concentration. The highest percentage of total AMF colonization was recorded for shade trees Millettia ferruginea (84 %) and Erythrina brucei (80 %) followed by intercropped perennial crops Ensete ventricosum (86 %), Catha edulis (85 %) and Coffea arabica (80 %) and the lowest percentage AMF colonization was recorded for Rhamnus prinoides (53 %) and Colocasia esculenta (52 %). Though found in almost all homegarden agroforestry practices and with broad coverage in Sidama agroforestry, some crops and vegetables such Brassica integrifolia and Cucurbita pepo, grown intercropped were found to be non-mycorrhizal as none of the AMF structures were recorded. The highest number of AM spore population was recorded in rhizosphere soils of Croton macrostachyus (1066 ± 19.33) and Catha edulis (1054 ± 53.12) and the lowest spore density was recorded for Dioscorea alata (100.00 ± 2.89) spore per 100 g of dry soil. The percentage fungal colonization in any individual plant species and spore population in the rhizosphere soils of that species did not correlate to each other and percentage AM root colonization and spore density of all plants in the agroforestry of Sidama were found significantly different at P < 0.05 level.

  • Tree diameter performance in relation to site quality in smallholder
           timber production systems in Gunungkidul, Indonesia
    • Authors: G. E. Sabastian; P. Kanowski; E. Williams; J. M. Roshetko
      Pages: 103 - 115
      Abstract: Abstract Smallholder farmers’ choices of tree species in the Gunungkidul region have been limited by lack of management information. This paper describes activities to help inform farmers’ choices of three common timber species—Tectona grandis, Swietenia macrophylla and Acacia auriculiformis—in agroforestry systems in the region through (1) developing models predicting tree diameter growth based on reference growth function and the growth retardation performance and (2) estimating the contributions of site quality variables to the diameter growth retardation of ≤5 and >5-year-old stands. A total of 48 farms were selected, representing three slope ranges and two soil types, with a circular sample plot of 10 m radius established at each farm. A Quadratic model for each timber species indicated that the age of the tree explains a high percentage of the variance in diameter growth. Diameter growth varies with tree age and responds differently in each soil type and slope position. A set of site quality variables were able to predict retarded diameter performances of each tree species in two group ages and two soil types. These results suggest that the models can inform farmers’ choices of tree species and management.

  • Abundance and diversity of flower visitors on wild and cultivated cacao (
           Theobroma cacao L.) in Bolivia
    • Authors: Claudia Chumacero de Schawe; Michael Kessler; Isabell Hensen; Teja Tscharntke
      Pages: 117 - 125
      Abstract: Abstract Despite the economic importance of Theobroma cacao, surprisingly little is known about its pollination ecology. Ceratopogonid midges are considered to be the main pollinators, but the limited available evidence on the sexual reproduction is based almost exclusively on cultivated cacao and knowledge is nonexistent for wild populations. We documented flower visitors in wild and cultivated plants by applying glue on 2237 flowers of wild and cultivated cacao trees in Bolivia to trap floral visitors. We caught 631 insects belonging to seven orders, corresponding to a mean capture rate of 0.3 insects per flower. The most abundant and diverse insect order on both cacao types was Hymenoptera, represented mainly by small parasitoids. Hymenoptera were more abundant on wild cacao, whereas species richness was higher on cultivated cacao. The abundance and species richness of Diptera were not significantly different between wild and cultivated cacao. However, species composition and proportion of Diptera species differed between both wild and cultivated cacao. Ceratopogonidae were only represented by 13 individuals belonging to seven species. Cacao pollen was carried by only a single specimen of Encyrtidae. We were thus unable to identify actual pollinators. We found significant differences among the visitor assemblages between wild and cultivated cacao, which suggest that midges alone were probably too rare to act as main or even sole pollinators of cacao in our study region. Potential additional pollinators would be small Diptera (e.g., Chloropidae and Phoridae) and Hymenoptera (e.g., Eulophidae and Platygastridae).

      Abstract: Abstract Ethiopia is one of the top five avocado producers in sub-Saharan Africa. Despite increasing recognition for its nutritional value and economic importance, information on smallholder avocado production systems across agro-climatic zones and determinants for tree productivity are literally lacking. Therefore, the objectives of this study were to examine the determinants for avocado tree holdings by smallholder farmers and investigate the effect of avocado production systems and management conditions on fruit yield by individual avocado trees in Southern Ethiopia. Data required for the study was collected through a combination of focus group discussions, household survey and field tree inventories. The data was analyzed using descriptive statistics, analyses of variance and linear regression methods using statistical software for social sciences (SPSS version 20). In the study region, avocado is mainly grown as an integral component of the coffee- and enset-based agroforestry systems. The number of avocado trees owned by smallholder producers was related to district, sex of household head, age of household head, educational status, land holding size, pest and disease damage and access to extension services. Productivity of avocado was significantly (p < 0.05) different between production systems. The highest avocado fruit yield was observed from trees grown in the coffee and enset-based agroforestry systems. However, the smallholder producers complain that the yields of coffee and enset grown under avocado trees could be very low. The total height of avocado trees was significantly (p < 0.05) different across the different production systems. The mean heights of matured (21–25 years old) avocado trees were 17.57 ± 0.86 m (±SE; N = 20) under coffee-based agroforestry system and 14.93 ± 1.24 m when grown as individual trees around homes. Proper extension support is needed to disseminate improved production techniques: encompassing proper tree spacing, tree training, pruning, soil amendments, growing optimum number of trees for successful pollination and improved harvesting.

  • The contribution of non-timber forest products (NTFPs) to rural household
           revenues in two villages in south-eastern Burkina Faso

      Abstract: Abstract Non-timber forest product (NTFP) providing species constitute substantial components of West African agroforestry systems and contribute considerably to local livelihoods. The aim of our study was to measure the annual economic contribution of NTFPs to local livelihoods in two villages of south-eastern Burkina Faso, focusing on the following specific questions: What is the average share of NTFPs in local household income' Which socio-economic variables affect total household income and NTFP dependency' How does NTFP income vary between (i) villages, (ii) ethnic groups and (iii) different income groups' Does NTFP income have an equalising effect on income inequality' Applying structured household surveys, we investigated the economic contribution of NTFPs household revenues among 155 households. NTFPs accounted for the second largest income share (45 %) of total household income compared to other income sources, i.e. crop production, livestock breeding and off-farm activities. We found that poorer households depend more on income from NTFPs than wealthier households, even though the latter earned more from NTFPs in absolute terms. In general, income from NTFPs had an equalising effect on income inequality. Furthermore, we discovered significant differences in NTFP dependency between the two investigated villages and across the three main ethnic groups (Gourmantché, Mossi, Fulani) reflecting different species compositions in their surroundings as well as different traditional uses and harvesting practices. Thus, we argue that management recommendations for agroforestry systems and poverty alleviation need to consider local differences with regard to site-specific species composition as well as ethnic-specific NTFP use patterns and habits.

  • The contribution of NTFP-gathering to rural people’s livelihoods around
           two timber concessions in Gabon
    • Authors: Donald Midoko Iponga; Christian Mikolo-Yobo; Guillaume Lescuyer; Fidèle Mba Assoumou; Patrice Levang; Julius Chupezi Tieguhong; Alfred Ngoye
      Pages: 157 - 168
      Abstract: Abstract NTFPs are often presented as a major contributor to livelihoods, as sources of food and cash, particularly for rural communities. There are few data available in Gabon to confirm this common assertion. This study was conducted on 127 households in 14 villages around two timber concessions in the south-eastern and south-western regions of Gabon for a period of one year. Conventional socio‐economic survey tools such as focus group discussions, census and semi-structured interviews with households were used for gathering the data. Results reveal that rural people depend on various sources of food and income for their livelihoods, but overall, the current contribution of NTFPs obtained from plant sources is insignificant compared to those from other activities. Odika (Irvingia gabonensis), ‘atanga sauvage’ (Dacryodes buettneri), fungus (Termitomyces spp.) and Gabon nut (Coula edulis) represent the main forest products commonly harvested by rural people. They are used primarily for subsistence, but the surplus is sold. The results of this study suggest that: (1) the main components of decree No. 137/PR/MEFP of February 4, 2009, that prohibits the logging of five multiple-use tree species over a period of 25 years in order to safeguard the sources of NTFPs, should be reviewed; and (2) state authorities and partners should promote projects aimed at increasing public awareness of the NTFP sector. These projects should include a census of NTFPs (for food, for medicine and for services), characterize their uses and identify the markets of target products as well as the development potential of NTFPs. Such projects could help Gabon and other Congo Basin countries to fix norms/standards for sustainable natural resource management and for enhancing the contribution of NTFPs to the national economy. This will be particularly relevant in the wake of dwindling oil revenues and the need to diversify and promote other revenue sources in the country.

      Abstract: Abstract Psidium guajava Linnaeus., popularly known as ‘Apple of Tropics’ is one of the major fruit crops undertaken on the bouldery riverbed lands of North-Western Himalayan region. Different predictive models were fitted to establish a functional relationship between biomass and collar diameter (CD) of the tree. Out of seven different models attempted viz, Monomolecular, Logistic, Gompetz, Allometric, Rechards, Chapman and Linear, Allometric model (Y = a Xb where Y = total biomass, X = collar diameter, a and b = parameter estimates) fulfills the validation criteria to the best possible extent and is considered as best performing. Allometric model has been fitted to find the relationship between biomass of different tree components and collar diameter. All the equations indicated high correlation between biomass and collar diameter and the R2 values for the fitted functions varied from 0.89 to 0.99. The calculated t-statistic values for all the components found to be non-significant (p > 0.05) which clearly reveals the validity and reliability of the model. The developed allometric models were used to estimate the biomass and carbon stocks of P. guajava plantations of the study site. The estimated total biomass varied from 1.43 Mg ha−1 in 4 year to 40.54 Mg ha−1 in 14 year old plantation. Mitigated carbon varied from 0.26 in 4 year to 7.75 Mg ha−1 in 14 year of plantation. The total biomass carbon stocks varied from 0.48 Mg ha−1 (4 year) to 13.66 Mg ha−1 (14 year) guava plantation.

      Abstract: Abstract Carbon sequestration in agroforestry systems plays an important role for climate change regulation. Policy makers make use of growth models for carbon estimations of the large scale projects in designing regulation. This study revealed the aboveground carbon sequestration potentials and established allometric growth models of four species in agroforestry. Based on the results, the aboveground carbon storages of Morinda tinctoria Roxb., Terminalia oliveri Brandis., Rhus paniculata Wall. and Emblica officinalis Gaertn. were 6.88, 6.59, 4.34 and 3.53 kg C tree−1, respectively. In comparison between two types of agroforestry, a mixture of M. tinctoria and E. officinalis had a higher carbon sequestration potential (1331 kg C ha−1) than a mixture of R. paniculata and T. oliveri (1151.40 kg C ha−1). A hyperbolic growth model and a basic quadratic model were the best-fit models for R. paniculata and E. officinalis, respectively, while a basic logarithmic model was the best fit for both M. tinctoria and T. oliveri. This study highlighted that both Akaike Information Criterion, Furnival index and coefficient of determination should be taken into consideration for model selection, as opposed to only considering the coefficient of determination. The study also pointed out that a mixture of M. tinctoria and T. oliveri should be considered as a tentative model for agroforestry plantations to enhance the carbon storage in semi-arid area in the future.

  • Economic assessment of agri-horticulture production systems on reclaimed
           ravine lands in Western India
    • Authors: V. C. Pande; R. S. Kurothe; Gopal Kumar; H. B. Singh; S. P. Tiwari
      Pages: 195 - 211
      Abstract: Abstract This study examines economic sustainability of agri-horticultural systems on reclaimed ravine lands in western India. Ravine lands are marked by their susceptibility to soil erosion along the course of river systems. Introduction of tree component with traditional crops on such marginal lands is beneficial not only in terms of short-term profitability but also resource conservation. Moringa oleifera (drumstick)- and Emblica officinalis (aonla)-based agri-horticulture trees with Phaseolus radiatus and Foeniculum vulgare crops have been examined as case studies based on data from a research farm adjacent to a major ravine system in western India. Drumstick, as green pod and also in dried powder form, is traditionally used as vegetable in Indian diet. Aonla is used in various forms as food as well as for medicinal purpose. This is marketed in different forms such as pickle, candy and dried powder. Enterprise budgeting analysis revealed that the net present values from M. oleifera + P. radiatus followed by F. vulgare and E. officinalis + P. radiatus followed by F. vulgare were 386 and 1190 USD ha−1, respectively, at 2012–13 local prices over a production cycle of 15 years. Saving in soil nutrients and soil carbon build-up worth 12–240 and 665 USD ha−1 was observed. Further, the land expectation value of E. officinalis-based agri-horticulture production system (1564 USD ha−1) revealed higher land value as compared to tobacco monocropping system (1039 USD ha−1). While the financial viability of these cropping systems proved their worth on the marginal lands of ravines in Gujarat, market and yield risks in crop component, examined through sensitivity analysis, need to be taken into consideration before recommending the agri-horticultural system to farmers. Nevertheless, in view of the declining profitability of the tobacco crop, largely grown on reclaimed ravine lands, an alternative production system, particularly aonla-based agri-horticulture system would help farmers explore alternative production system suiting to their resource endowments.

      Abstract: Abstract Agroforestry intercropping systems have been developed as an alternative to conventional monocropping systems to address environmental, social and economic issues in a wide array of agricultural contexts. As research on the biological properties of these systems tends to demonstrate their potential, fostering their integration in agricultural landscapes requires an in-depth understanding of local stakeholders’ perceptions. Our study used the strengths, weaknesses, opportunities and threats approach in combination with the analytical hierarchy process (SWOT-AHP) to investigate the factors influencing local stakeholders’ decision to integrate agroforestry intercropping systems in two Regional County Municipalities and their perception of the relative suitability of three agroforestry intercropping system designs (crop-oriented, tree-oriented and landscape aesthetic-oriented). We conducted focus groups with farmers, farm and forestry advisors, urban planners and local authorities in a very intensive and a very extensive agricultural landscape in Quebec (Canada) and compared the results between stakeholders within and across the areas. Our results show that social factors seem to have more impact than biophysical factors on the decision to integrate agroforestry intercropping systems in intensive and extensive agricultural landscapes. The relative value given to the decision factors varies greatly across stakeholders’ categories and areas. Agroforestry intercropping systems designed to meet crop production needs or landscape aesthetic purposes are perceived as more suitable in both agricultural contexts than the tree-oriented design. Our results highlight crucial issues for agroforestry intercropping system deployment and the development of relevant agroforestry system designs through collective decision-making processes.

  • Experimental addition of olive mill waste compost in an old agroecosystem:
           identifying main short-term vegetation responses

      Abstract: Abstract Olive mill wastewater (OMW) is the main residual product of olive processing and its disposal can represent a relevant environmental issue in Mediterranean countries. OMW is characterised by high pollutant load, salinity and phytotoxic levels of polyphenols, but also by a high amount of organic compounds and plant mineral nutrients. In this perspective, a technology named MATReFO was developed, with a final dry product easy to transport for commercial use. Here, we assessed the short-term effects of OMW and MATReFO applications on spontaneous vegetation in an old agroecosystem. Following a randomized block design soil was amended with different quantities of OMW or MATReFO and vegetation was sampled for 4 years after the treatments. Multivariate and univariate analyses of plant data showed that: (1) only high volume of MATReFO affected spontaneous vegetation, whereas OMW and low volume mixture addition did not determine significant effects; (2) plant species composition and abundance varied significantly among years and exhibited considerable variation over the study period, particularly with high volume of MATReFO; (3) vegetation dynamic had already undergone first steps of natural succession in control and almost all treatments. Our results revealed no negative effects of olive mill waste compost addition in plant community assemblage, since vegetation changes can be mainly related to the abandonment of soil tillage. Therefore, we can assert that OMW and MATReFO can be discharged in abandoned agroecosystems without short-term effects on natural vegetation.
