Table 1 Major approches in classification of agroforestry systems and practices (Nair 1985) Figure 1 Categorization of agroforestry systems based on the nature of components (with examples of common sub-systems and practices under each system.) Classification of Agroforestry systems Nair ( 1987) has classified the agroforestry systems based on the following four criteria. 8, pp, Sinclair FL (1996) University Research and Agroforestry Development in Sri Lanka.  On  the best bases of nature of components the Agroforestry is divided into four sections,  In this system the arable crops are grown suitably mixed with tree crops this means the agricultural crops are grown along with the perennial trees in the same field.The individual subclasses of the agree with agrisivilcultural system are described:-(i) Improved fallow species in shifting cultivation:-  in this system the fallow land is used for the growing of perennial trees at the end of shifting cultivation.This practice degrees is soil erosion in the subsequent years and recovers depleted soil  and  nutrients. 4. In recent decades in northwest Vietnam, Arabica coffee has been grown on sloping land in intensive, full sun monocultures that are not sustainable in the long term and have negative environmental impacts. The most acute problem is in the, inappropriate use of the word system itself, which not only conflicts with the, central concept of holism in general system theory but, as Nair (1989c) himself, points out, also conflicts with the concept of generalising ‘land use systems’, or ‘farming systems’, at the level of the ‘household’ or ‘human decision-, making unit’, used in ICRAF’s diagnosis and design procedures for agro-, forestry development (Raintree, 1983, 1990) and the farming systems literature, The confusion arises because agroforestry, as it is practiced, is very rarely, a whole farm or forest system. This criterion can not be applied universally, because extensive, but nevertheless intentional and interactive use of mixed, vegetation is widespread in both the wet (Prance, 1990) and the dry (Breman, and Kessler, 1995) tropics and in more temperate conditions in Europe, use, of extensive livestock grazing in woodlands to benefit both farmers and. Kluwer Academic Publishers, Springer. Leakey (1996) has highlighted the incremental nature of, increasing the number of trees on farms over considerable time periods, which, can be viewed as a successional sequence towards a mature agroforest at the, farm scale, with increasing ecological integrity and consequent stability and, sustainability benefits.

This gradient is represented by three landscapes that grade from a dense hedgerow network landscape to an open landscape. use and on the other as a set of integrated land use practices (Sinclair, 1991). The purpose of a general classification is to identify different types of agroforestry and to group, those that are similar, thereby facilitating communication and the organized storage of infor-, mation. it is appropriate to continue classification. It paid particular attention to the role of the aromatic resin bearing species of Boswellia and Commiphora in poverty alleviation and climate change adaptation in the region. To evaluate understand and seek to improve them requires their classification into different categories. These range from “growing trees on farms” (Young 1997) to more technical definitions, such as that by Sommariba (1992) who defines agroforestry as a form of multiple cropping which satisfies three basic conditions: 1. In: Gholz HL (ed) Agroforestry: Realities, Possibilities and Potentials, pp 137–154. it, by-products of fodder and/or fuelwood may also be obtained from the fence. Simmonds NW (1985) Farming systems research: A Review. The theoretical framework of the study was based on the conceptual framework for sustainable development or sustainability. FMNR is reported to deliver a number of positive impacts, including increasing agricultural productivity through soil fertility improvement and feed for livestock, incomes, and other environmental benefits. The author, co-founder of the World Agroforestry Centre (ICRAF), is a pioneer in the establishment modern agroforestry. Agric Syst 24: 95–117. He is a leading world authority and a pioneering researcher and educator in agroforestry. 3. forestry is and to clarify the level of organization at which it is appropriate, to distinguish units of classification. non timber forest products (from both overstorey and understorey species), trees on grazing land and farm woodlots. This was not surprising given the pioneering role of, the AFSI project in an emerging subject area and its wide geographical and, institutional spread. Common grazing or forest areas, while accessed by farmers, may be. Analyse the impacts of alternative land-use scenarios (and other mitigation options) aimed at maximising climate mitigation potential while minimising loss of biodiversity and ecosystem services and avoiding undesirable ecological and socio-economic effects; The present study objective was to identify and describe the RAS in mature plantations existing in Phatthalung province. This paper reviews the scientific evidence related to the contexts in which FMNR is practiced across sub-Saharan Africa, how this influences the composition of regenerating vegetation, and the resulting environmental and socioeconomic benefits derived from it. Foresta and Michon, 1996). It is useful, therefore, to view the garden-live fence complex as a spatial group, of two practices because of their discrete functionality, to identify the spatial linkage between the two practices, however, because, in the presence of marauding animals, the performance and prospects of a, garden surrounded by a live fence may be quite different from that of a garden, that is not so protected. This makes it more useful, from an agroforestry perspective, to, classify and describe such practices, considering their role within the systems, of which they form a part, rather than to attempt to classify the whole farm, or forest systems that they are in. 1.

A secondary scheme further classifies these. hedgerow intercropping in the tropics which also bears this label), windbreaks, riparian buffer strips, silvopasture and forest farming (Merwin, 1997). The partial nature of agroforestry can be illus-, trated using examples from where trees have been incorporated in some, contemporary temperate farming systems (Figure 1). The AFSI database, and the original inventory sheets upon which it was based, were transferred from ICRAF to Bangor in 1990 and evaluated in terms of, generally accepted methods of systems analysis (Sinclair et al., 1991). -from Authors.

A new scheme is proposed that uses the ‘practice’ rather than the ‘system’ as the unit, of classification. 3. Obviously, to locate the types of practice identified within bioclimatic regions and we.

In: Gordon AM and Newman SM (eds) Temperate Agroforestry, Systems, pp 9–84. of trees by people, where a regular, frequent and multiple harvest is obtained, The second criterion used in the classification is the predominant use of, the land on which the practice takes place.

Clearly this scheme (Figure 4) splits agroforestry up into a series of major, types on the basis of both ecological and management criteria.

The objectives of the project were to: Author’s address: The specific objectives of the project are: Quantify the role of biodiversity in terrestrial ecosystems in South and Mesoamerica in mitigating climate change; To develop databases and tools for monitoring and evaluation of the impact of scaling up and out the adoption of trees on farms. The above-mentioned system has been well known for its potential in improving and sustaining agricultural production through increased soil fertility, climate change amelioration, breaking the current challenge of food insecurity and poverty circles, besides raising the livelihood of rural poor owing to diverse products derived from the systems such as food, fuelwood, timber and source of income. Agroforestry students at Bangor over the past decade, or so have helped to refine the scheme presented here through their use and, discussion of it as part of their course work.

The AF Systems Inventory (AFSI) being undertaken by ICRAF provides the background information for an approach to classification. In scientific agricultural practices, agroforestry systems are getting wide recognition due to its healthy integration of woody perennial trees, herbaceous crops and livestock in unit areas which are socially acceptable, economically viable and ecologically sound. These are clearly types of land that are used for different, purposes and are not necessarily interchangeable. al., 1995) and the feeding value of tree fodder (Thapa et al., 1997). The major gains are, to improve the resolution with which practices that have similar underlying, ecology and prospects for management are grouped and to broaden the, classification of agroforestry to more fully encompass people’, were responsible for implementation of the database and Alan W, Lorraine Gormley spent many hours analysing and enumerating system, descriptions using it. These data had been contributed from various parts, of the world by different regional coordinators who had interpreted data. 8 Evaluation of agroforestry potential in sloping areas Anthony Young International Council for Research in Agroforestry, P.O. © 2008-2021 ResearchGate GmbH.
