Received 5 March, 2018; Accepted 24 April, 2018 The study is essential in reducing germination time of Treculia africana var. inversa. The effect of three different concentrations of sucrose namely 2, 3 and 4% were investigated on the in vitro regeneration of embryo explants of T. africana Decne. on the media of Murashige and Skoog (MS) and Gamborg et al. (B5) respectively without any growth regulator. The experimental design was a 2 × 5 factorial in a completely randomized design with each treatment consisting of ten replicates. Results showed that while both media including control (contains agar only) supported the in vitro regeneration of T. africana embryo explants, B5 medium was found to be significantly superior (P≤0.05) to MS medium in all the growth parameters studied. B5 medium at 4% sucrose elicited the best response in all the growth parameters determined while control gave the least response. The protocol reported here can be used for large scale propagation of true-to-type T. africana plants within a short time for the purpose of improvement through genetic transformation (mutagenesis) and the development of a viable conservation programme.

  • Agroforestry : Fact-Sheet
    Agroforestry fact sheet Agroforestry is the mixture of trees and crops in cultivated parcels. It was a traditional system in both tropical and temperate countries before agriculture intensification during the last century. Very recent results show that it may be a key option for the future of modern agriculture, including in temperate countries. 10 years ago, agroforestry was still ignored by farmers, foresters, policy makers of developed coun- tries. But times have changed. Agroforestry is an utmost example of ecological intensification : it in- creases land productivity and offers at the same time many environmental services. A French national scheme for planting half a million hectares of agroforestry during the next 25 years was based on res- ults obtained by INRA, Montpellier. A walnut – wheat agroforestry plot at the Restinclières farm, tree pruning time (left) Monitoring water sap flow through tap roots and superficial roots to document the hydraulic lift on walnut agroforestry trees (right) Increase of productivity with agroforestry The mix of trees and crops is the fundamental principle of agroforestry. INRA researchers showed that the production from one hectare of a walnut/wheat mix is the same as for 1.4 hectares with trees and crops separated. This is a 40% increase in productivity, far better than any other innovation intro- duced by agronomists in the recent past. This is achieved with an optimal 50 to 100 trees/hectare dens- ity, and an appropriate management of the system (tree line orientation, tree pruning regime, winter crops). Agroforestry trees grow very fast, faster than trees in forest plantations. Rightly associated and appropriately managed, trees and annual crops establish a synergy in the use of the vital resources of light, water and soil nutrients.

  • Course Handout for Introduction to Forest Gardening
    COURSE HANDOUT FOR INTRODUCTION TO FOREST GARDENING Complied by Jess Clynewood and Rich Wright Held at Coed Hills Rural Art Space 2010 ETHICS AND PRINCIPLES OF PERMACULTURE Care for the Earth v Care for the people v Fair shares PRINCIPLES Make the least change for the greatest effect v Mistakes are tools for learning v The only limits to the yield of a system are imagination and understanding Observation – Protracted and thoughtful observation rather than prolonged and thoughtless action. Observation is a key tool to re-learn. We need to know what is going on already so that we don’t make changes we will later regret. Use and value diversity - Diversity allows us to build a strong web of beneficial connections. Monocultures are incredibly fragile and prone to pests and diseases – diverse systems are far more robust and are intrinsically more resilient. Relative Location and Beneficial Connections – View design components not in isolation but as part of a holistic system. Place elements to maximise their potential to create beneficial connections with other elements. Multi-functional Design – Try and gain as many yields or outputs from each element in your design as possible. Meet every need in multiple ways, as many elements supporting each important function creates stability and resilience. Perennial systems – minimum effort for maximum gain Create no waste - The concept of waste is essentially a reflection of poor design. Every output from one system could become the input to another system. We need to think cyclically rather than in linear systems. Unmet needs = work, unused output = pollution. Stacking – Make use of vertical as well as horizontal space, filling as many niches as possible.

We tested the effects of surface applications of wood-derived biochars (applied at 7.5 t ha 1) on soil · − physiochemical properties (N, P, K, pH, soil moisture content, organic matter content, and bulk density) in three land-use types: agriculture (Camellia sinensis monoculture), agroforestry (C. sinensis with shade trees), and secondary forest (Dipterocarpus dominated) assessed over seven months. We found significant positive effects of biochar on soil physiochemical properties in all land-use types, with the strongest responses in the most degraded tea monoculture sites. Although biochar had no significant effect on soil N and K, it improved soil P—the primary nutrient most commonly limiting in tropical soils.

  • Agroforestry Benefits and Challenges for Adoption in Europe and Beyond
    sustainability Review Agroforestry Benefits and Challenges for Adoption in Europe and Beyond Maya Sollen-Norrlin 1, Bhim Bahadur Ghaley 2 and Naomi Laura Jane Rintoul 1,* 1 School of Psychology and Life Sciences, Canterbury Christ Church University, Canterbury CT1 1TE, UK; [email protected] 2 Department of Plant and Environmental Sciences, Faculty of Science, University of Copenhagen, 2630 Taastrup, Denmark; [email protected] * Correspondence: [email protected] Received: 3 July 2020; Accepted: 18 August 2020; Published: 27 August 2020 Abstract: Soil degradation is a global concern, decreasing the soil’s ability to perform a multitude of functions. In Europe, one of the leading causes of soil degradation is unsustainable agricultural practices. Hence, there is a need to explore alternative production systems for enhanced agronomic productivity and environmental performance, such as agroforestry systems (AFS). Given this, the objective of the study is to enumerate the major benefits and challenges in the adoption of AFS. AFS can improve agronomic productivity, carbon sequestration, nutrient cycling, soil biodiversity, water retention, and pollination. Furthermore, they can reduce soil erosion and incidence of fire and provide recreational and cultural benefits. There are several challenges to the adoption and uptake of AFS in Europe, including high costs for implementation, lack of financial incentives, limited AFS product marketing, lack of education, awareness, and field demonstrations. Policies for financial incentives such as subsidies and payments for ecosystem services provided by AFS must be introduced or amended. Awareness of AFS products must be increased for consumers through appropriate marketing strategies, and landowners need more opportunities for education on how to successfully manage diverse, economically viable AFS.

  • Chimpanzees Balance Resources and Risk in an Anthropogenic Landscape of Fear Elena Bersacola1,2,3*, Catherine M
    www.nature.com/scientificreports OPEN Chimpanzees balance resources and risk in an anthropogenic landscape of fear Elena Bersacola1,2,3*, Catherine M. Hill2 & Kimberley J. Hockings1,3 Human-wildlife coexistence is possible when animals can meet their ecological requirements while managing human-induced risks. Understanding how wildlife balance these trade-ofs in anthropogenic environments is crucial to develop efective strategies to reduce risks of negative interactions, including bi-directional aggression and disease transmission. For the frst time, we use a landscape of fear framework with Bayesian spatiotemporal modelling to investigate anthropogenic risk-mitigation and optimal foraging trade-ofs in Critically Endangered western chimpanzees (Pan troglodytes verus). Using 12 months of camera trap data (21 camera traps, 6722 camera trap days) and phenology on wild and cultivated plant species collected at Caiquene–Cadique, Cantanhez National Park (Guinea-Bissau), we show that humans and chimpanzees broadly overlapped in their use of forest and anthropogenic parts of the habitat including villages and cultivated areas. The spatiotemporal model showed that chimpanzee use of space was predicted by the availability of naturalised oil-palm fruit. Chimpanzees used areas away from villages and agriculture more intensively, but optimised their foraging strategies by increasing their use of village areas with cultivated fruits when wild fruits were scarce. Our modelling approach generates fne-resolution space–time output maps, which can be scaled-up to identify human-wildlife interaction hotspots at the landscape level, informing coexistence strategy. Te majority of the world’s terrestrial biodiversity is impacted by humans 1,2. Anthropogenic activities, includ- ing hunting and forest conversion to agriculture, pasture land and urban areas are causing signifcant wildlife population declines globally 3.
