there has been some decline in the land potential capacity in many developing countries, and depending on location,the multi objective management strategy of agroforestry can make effective use of natural resources to be feasible.environmental principles which are effective on agroforestry systems and their components, together with climaticfactors, are the important parameters which been evalu...

Over the past 20 years, the biodiversity associated with shaded coffee plantations and the role of diverse agroforestry types in biodiversity conservation and environmental services have been topics of debate. Endophytic fungi, which are microorganisms that inhabit plant tissues in an asymptomatic manner, form a part of the biodiversity associated with coffee plants. Studies on the endophytic f...

Agriculture is the human enterprise that is most vulnerable to climate change. Tropical agriculture, particularly subsistence agriculture is particularly vulnerable, as smallholder farmers do not have adequate resources to adapt to climate change. While agroforestry may play a significant role in mitigating the atmospheric accumulation of greenhouse gases (GHG), it also has a role to play in he...

Insectivorous birds reduce arthropod abundances and their damage to plants in some, but not all, studies where predation by birds has been assessed. The variation in bird effects may be due to characteristics such as plant productivity or quality, habitat complexity, and/or species diversity of predator and prey assemblages. Since agroforestry systems vary in such characteristics, these systems...

Agroforestry is a science which has the potential to contribute to the improvement of rural livelihood. Due to capacity of its various forms, it offers multiple alternative and opportunities to the farmers to enhance farm production and income, while protecting the agricultural environment. The local inhabitants of Ladakh region, a Cold Arid Desert, have their traditional Agroforestry system wh...

Agroforestry on small-scale farms has potential to provide important ecological services, such as carbon sequestration and maintenance of biological diversity, while also providing on-farm products for domestic use and marketing. Payments for environmental services (PES) are an increasingly popular mechanism for encouraging production of ecological services on agricultural lands and may also co...

Losses of biodiversity and ecosystem functioning due to rainforest destruction and agricultural intensification are prime concerns for science and society alike. Potentially, ecosystems show nonlinear responses to land-use intensification that would open management options with limited ecological losses but satisfying economic gains. However, multidisciplinary studies to quantify ecological los...

Agriculture faces the unprecedented task of feeding a world population of 9 billion people by 2050 while simultaneously avoiding harmful environmental and social effects. One effort to meet this challenge has been organic farming, with outcomes that are generally positive. However, a number of challenges remain. Organic yields lag behind those in conventional agriculture, and greenhouse gas emi...

The objective of this paper is to empirically test the hypothesis that reducing uncertainty for farmers through investment in human capital increases the likelihood of participation in an agroforestry development program. A model based on Keynes’s notion of profit expectations and “weight” is developed in order to gain some insight into agroforestry adoption behavior. Data was collected near th...

Removing atmospheric carbon (C) and storing it in the terrestrial biosphere is one of the options, which have been proposed to compensate greenhouse gas (GHG) emissions. Agricultural lands are believed to be a major potential sink and could absorb large quantities of C if trees are reintroduced to these systems and judiciously managed together with crops and/or animals. Thus, the importance of ...
