The aim of the AgroFE project is to play an important role in Agroforestry trainings in European dimension. Depending on the European countries, states or professional organizations and training actors try to reintroduce agroforestry training and education in different levels. The main objectives are to make a synthesis of needs and expectations, based on the present existing training actions a...

Agroforestry, the deliberate integration of trees into agricultural operations, sequesters carbon (C) while providing valuable services on agricultural lands. However, methods to quantify present and projected C stocks in these open-grown woody systems are limited. As an initial step to address C accounting in agroforestry systems, a spatial Markov random field model for predicting the natural ...

We compared post-agricultural succession across the range of farming activities practiced in Guatemala’s northern lowlands: agroforestry, swidden, ranching, and input-intensive monocultures. At 10 sites over 13 to 40 months we assessed the following characteristics of trees and shrubs that were 1 cm diameter at breast height: height, basal-area accumulation, recruitment of all individuals and f...

more attention and are increasingly seen as sustainable options to many of the land management practices in developing countries. In current attempts to identify methods of sustainable agricultural intensification and food production, agroforestry is put forward as a key future land-use practice due to its large potential for climate change mitigation and adaptation, as well as its role in prot...

Tracing sources of water utilised by plants is important to understand species interactions in intercropping/agroforestry systems, particularly where species vary greatly in life-form. Isotopic techniques are an increasingly common means to trace water sources. The distribution of stable isotopes of water within the soil±plant±atmosphere continuum is indicative of a range of hydrologic processe...

Agricultural intensification has had unintended environmental consequences, including increased nutrient leaching and surface runoff and other agrarian-derived pollutants. Improved diagnosis of on-farm nutrient dynamics will have the advantage of increasing yields and will diminish financial and environmental costs. To achieve this, a management support system that allows for site-specific rapi...

The resource capture approach developed by John Monteith has been applied in studies of a wide variety of plant species and cropping systems in the tropics over the past 18 years. The purpose of this review is to highlight the progress made and the new challenges which lie ahead. The foundation for this approach was the establishment of ‘response surfaces’ for the development and growth of trop...

The present study investigates the relations between statistical measures of TerraSAR-X backscatter coefficients and field inventory measures for tropical agroforestry systems in Central Sulawesi, Indonesia. The background of the study is to evaluate the potential of spaceborne SAR missions for the spatially explicit estimation of horizontal and vertical structure elements of land use systems i...

Regulating the shade provided by overstory trees is important in the management of shaded-perennial agroforestry systems. In order to compare the merits of commonly used light-assessment techniques that could potentially be useful to farmers and extensionists and to quantify the extent of shading in multistrata agroforestry systems, understory photosynthetically active radiation (PAR) was measu...
