        Faced with the growing problems of climate change, ecosystem degradation, declining agricultural productivity, and uncertain food security, modern agricultural scientists look for potential relief in an ancient practice. Agroforestry, if properly designed, can mitigate greenhouse effects, maintain ecosystem health and biodiversity, provide food security, and .   Certification of tropical agroforestry crops is now well established, and a major success in the past decade has been significant uptake and acceptance by farmers, food companies, and retailers. This suggests the strong potential of certification to deliver conservation benefits, but there is often only indirect evidence of positive.

        The rate and extent to which biophysical resources are captured and utilized by the components of an agroforestry system are determined by the nature and intensity of interactions between the components. The net effect of these interactions is often determined by the influence of the tree component on the other component(s) and/or on the overall system, and is Cited by: 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 nmental principles which are effective on Agroforestry systems and their components, together with climaticfactors, are the important .

      The main challenges for research on these tropical agroforestry systems are the assessment and improvement of their efficiency. The analysis of trade-offs between the different ecosystem services provided by these systems is ultimately intended to design new ecologically intensive cropping systems, combining economic efficiency and ecological. Agroforestry is an age old practice throughout the world, but its recognition as a science is nearly three decades old. The scientific and systematic research on tree-crop interactions, in India, started in late 's and got major support and impetus with the establishment of All India Coordinated Research Project (AICRP) on Agroforestry in by s: 1.

Perhaps the title of the book is misleading in that the book does not include or cover all existing agroforestry systems in the tropics and geographical regions in the tropics. Additionally, some of the systems described are outside the tropical boul;ldaries of 5" Nand S : Hardcover.

The multifunctional agroforestry systems in tropics region offer enumerable ecological benefits such as carbon sequestration, mitigation of climate change, enhancing soil fertility and water use efficiency, biodiversity conservation, biological pest control, sustainable land use, shelterbelt and windbreaks, microclimate amelioration, breaking the.

Agroforestry Systems in the Tropics. This book consolidates the descriptive results of a pantropical project called Agroforestry Systems Inventory (AFSI), undertaken by the International Council for Research in Agroforestry (ICRAF) from to -3­ sequence.

In agroforestry systems there are both ecological and econonical interactionsbetween the different components. This definition implies that: i) agroforestry normally involves two or more species of plants (or plant and animals), at least one of which.

is a woody perennial. About this book. Introduction. Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash.

Agroforestry systems in major ecological zones of the tropics and subtropics. Nairobi, ICRAF, 15 pp. Through its Agroforestry Systems Inventory, ICRAF has gathered together, evaluated, summarized and distributed information on systems and associated practices in different parts of the tropics.

Classification was carriedFile Size: 65KB. Agroforestry is an ancient practice and also the farmers are too much familiarized with it in Ethiopia. It contributes incredible benefits via socio-economic and environment.

The main idea of this paper is to review Agro-forestry system/practices and its contribution in Ethiopia. Most common types of agroforestry practices are home garden, farmland, woodlot and coffee Cited by: 1. Other agroforestry systems are valued in semiarid tropics, including protein banks and apiforestry.

The most important food crops that are grown in tree-crop systems in the semiarid tropics are cereals (maize, rice and various species of millet) or by: 4. Traditional agroforestry systems (TAFS) may be described as a set of age-old agroforestry systems which are generally devoid of intentional intensified cultivation of agricultural or forage crops and which have been practiced across the world with varying structure, function, socio economic attributes and ecological Size: 1MB.

Communities of species have coevolved within ecological zones. The presence and diversity of plant communities and associated animals, soil organisms, and symbionts can be categorized in relationship to gradients of moisture and temperature. Isolation enhances speciation. Major agroforestry practices or technologies in the humid tropics include homegardens, perennial crop based systems, shifting cultivation, alley cropping, improved fallows and rotational tree fallows.

Other agroforestry systems are valued in the humid tropics, including relay cropping, multilayer tree gardens, Cited by: 4. Two agroforestry management systems are reviewed which currently appear feasible for implementation in many industrialized countries of the temperate zone.

These two systems include: 1) Animal grazing and intercropping under managed coniferous forests or plantations; and 2) Multicropping of agricultural crops under intensively managed, high value Cited by:   Perhaps the title of the book is misleading in that the book does not include or cover all existing agroforestry systems in the tropics and geographical regions in the tropics.

Additionally, some of the systems described are outside the tropical boul;ldaries of 4/5(2). In spite of these anomalies, agroforestry stands as a means of halting the vicious circle of deforestation, soil erosion and other environmental problems facing the ecological zones.

Applying ecological modeling of complex agroforestry systems, section three demonstrates the use of computer-based designs to ensure profitability.

The final section addresses the socio-economic aspects of agroforestry, supplying in-depth knowledge of various farming systems and discussing the technological tools that benefit society in. Agroforestry -- the practice of integrating trees and other large woody perennials on farms and throughout the agricultural landscape -- is increasingly recognized as a useful and promising strategy that diversifies production for greater social, economic, and environmental benefits.

In terms of ecozones the tropics comprise the seasonal tropics (savanna zone) and the humid tropics. The subtropics are delimitated from the tropics by thermal criteria, i.e., the frost limit or the +18°C isotherm of the coldest months in the lowlands.
