The book addresses both academics and practitioners interested in land degradation and conservation of areas with agrosilvopastoral land use in Mediterranean environments or other semi-arid areas with strong seasonal contrasts. Animal component changes can accelerate some aspects of nutri- ment cycling by returning manures and urine to the soil.

Cultural practices, such as mechanized harvest of crops, “henifica- cion,” or “ensilado,” are interfered with by the trees. Classification of agroforestry systems.

Keyword Advanced Browse all content Thesaurus. Small farmers, with land limitations, may use the forest to produce food from animal origin milk, meat without sacrificing areas dedi- cated to crops. The management and conservation of dryland forests and agrosilvopastoral systems often require different approaches to those suited to humid forests. Please enter a valid email address. Shade protects animals from excessive heating from direct radiation and reduces internal temperature stress.

The Agro-Silvopastoral System (ASPS)

Investigacion en manejo forestal y agroforestal: Geographic Entities see more detailsand general considerations within a framework of sustainability – including activities towards the development of various types of agrosilvopastoral practices. These objectives seem t o be divergcnt, but with the appropriate use o f known agroforestry practices, it may be possible to accomplish both production and conservation goals.

Turrialba Costa Rica 9 3: These combinations may be simultaneous or alternate in time and space, and aim to achieve sustain- able production. More generally, forests and trees in drylands are essential for sustaining rural livelihoods. Wright-Allen, Cambridge, pp. We would like to contact you via email from time to time to seek feedback about ways in which we can improve My CABI such as adding or changing its functionality, new features and content.

Journal of Sustainable Agriculture, Vol. Although these statistics exist, it is unknown at the farm level what area percentage is managed under ASPS or has a forest component.

Although reduced in size, these activities still form a main productive component of the economy in this region. However, one has to be aware that ASPS is not a total solution to tropical problems. Gomez-Pompa, A, Flores, J. The practical objective of agrosilvopastoral ASPS systems, in areas fundamentally devoted to cattle production, is to produce goods, traditionally forestry goods such as fuelwood, poles, and timber. Because most of the farmers in the humid tropics live on and farm small parcels, it is financially too risky for them to experiment with small plantations of trees.

The alder trees, selected for their fast growth in year rotations trees reach cm diameterprovide timber, fuelwood, and also have the added advantage of being an actinorhizal tree it is host to the nitrogen-feg actinomycete Frankia in nodules of their root tissue ; and b Another one developed in the Atlantic lowlands, where laurel Cor- dia alliodora is frequently found in pastures.

Essentially, these systems are a model of production and conservation based on silvi-cultural practices complementary to pre-existing agricultural activities.

Agrosilvopastoral systems: a practical approach toward sustainable agriculture.

Natural leaf fall and pruning help to increase the availability of water, light, and nutrients to system components. The flow diagram Figure Iredrawn from Bronsteinallows a quick and clear view of inputs, outputs, and relationships among components. An example of the first c a s d e e s in pastures-has been evaluated in the grasslands of the College of Agriculture of the Humid Tropical Region known as EARTH in SpanishLas Mercedes de Guacimo, Costa Rica, where 29 different tree species have been identified within an area of approximately hectares Table 1.

Jansen divides these spatial sequences according to their proximity to human settlements in infields croplands and outfields forest and pasture.

In addition to direct advantages, farmers may also obtain economic benefits from fuelwood, timber, posts, and forage, which are used eventually on the farm for cattle management. Agroforestry practices continued into the Spanish colonial times.

In this meeting, the bio- logical-productive importance of AFS was recognized, and strong support was given to a series of recommendations leading to promote the active participation of rural communities in the preparation and application of the most appropriate AFS for each given situation.

College, in the Atlantic lowlands of Costa Rica. Commodities and Products see more details such as fuelwood, poles, and timber. It is important to realize also that disadvantages exist Ruiz, A research component on natural resources with emphasis in xystems, soil, and water was added. A common feature is the coexistence of extensification and intensification, sjstems different problems of degradation.

Other examples of successful ASPS that have remained throughout time are: In the third section studies on soil water dynamics and soil degradation are presented, including a modeling approach for analyzing stability in grazing systems.

In this sense it seems correct to consider the development of ASPS as the result of a co-evolutionary process between humans and their environment. From this point sytems view, these practices may be applied in a wide range of ecological and productive conditions.

Therefore, it is proposed: Properties see more details based on silvicultural practices complementary to pre-existing agricultural activities. In Serra da Estrela, high annual variation in temperature, i.
