Conservation biological control in a multi-strata agroforestry system
Polyculture agroforestry is a new sustainable agriculture system modelled on the plant structural and species diversity of native oak savanna. Advocates of the system claim that it will advance conservation goals by providing ecosystem services like habitat provision and carbon sequestration, but …

Nitrogen Dynamics of the Acacia Senegal Agroforestry System in the Sudan
… types dominated by the Genus<em> Acacia</em>. Agroforestry systems evolved, the most notable of which is Acacia senegal agroforestry system (ASAS). It yields gum acacia, fuel and fodder and improved soil N, P, and pH and stability against erosion.</p> <p>This study investigated the climatic, …

Moths & Legends The contribution of chitoumou, the edible caterpillar Cirina butyrospermi, to food security, agriculture and biodiversity in a low-intensity agroforestry system
The global food system is essential for sustaining human life, yet in its current form it does so at a great cost to both human and environmental health. Food insecurity and diet-related disease are responsible for 70% of deaths worldwide, and the global extinction rate is ~1000 times estimated …

Balance de carbono de dos agroecosistemas en un suelo del distrito de riego del Río Zulia, departamento norte de Santander-Colombia
… with Cacao trees was used as a reference soil (agroforestry). For SOC balance estimation, measurement of organic carbon (OC) inputs was determined from necromass, roots, microbial biomass, and urea applications. The CO2 and CH4 emissions were also measured. Results showed that the change in the …

A Systems Approach to Modelling the Effects of Climate Change on Agroforestry: A Case Study in Western Tanzania
… modes of agricultural adaptations, such as agroforestry, that these farmers can easily adopt to improve their resiliency to the effects of climate change. System dynamics modelling is a cost-effective tool to simulate the long-term behaviour of agroforestry systems under future climate …

The double life of an insect pathogen: Metarhizium as a plant symbiont and its genetic diversity in coffee agroecosystems
… All those functions could be valuable as ecosystem services provided by these fungi to plants in sustainable agricultural schemes. However, these fungi are poorly considered in an ecological context and data about their diversity and abundance in agricultural soils and in association with …

Intensification of agriculture and livestock based on low carbon technologies in the Amazon and Atlantic Forest
… as Integrated Crop-Livestock-Forest (ICLF) or Agroforestry Systems (AFS), can support increased agricultural production while recovering and preserving the environment. In view of this, we identified in the Amazon, the pattern of land use by farmers who adopt sustainable technologies, …

Variability of physical, chemical and hydraulic parameters in soils of Mt. Kilimanjaro across different land uses
… often decrease important functioning of soil systems. In order to understand the soil complexity, sophisticated technologies to measure soil properties and processes at high spatial resolutions are needed. This study addresses the heterogeneity of various soil physical, chemical and hydraulic …

A physiological basis to crop improvement and agronomic development
… community is operating within two limits of food system: (i) the quantity of food that can be produced under a given climate; and (ii) the quantity of food needed by a growing and changing population. Therefore, taking food security successfully into the future requires novel approaches to boost …

Decepa de plantas jovens de eucalipto em um sistema agroflorestal: dinâmica de copa e crescimento
O crescimento e a dinâmica de copa de plantas intactas e decepadas de dois clones de eucalipto foram avaliados em sistema agroflorestal no espaçamento 9,5 x 4,0 m em Vazante, MG (17°36 09 S e 46°42 02 W). Plantas intactas foram comparadas com brotações provenientes de plantas decepadas aos 9 e 12 …

Farmers’ Motivation and Biophysical Impact of using Cordia africana and Albizia coriaria on Coffee-Bean Intercrops in the Mt Elgon Region (Uganda)
… deliberate integration of trees into farming systems (agroforestry) has been practiced traditionally in the Mt. Elgon region of Uganda since time immemorial, with modernisation of society and commercialisation of agriculture, many farmers are motivated to dismantle agroforestry systems in …
