Rainforests are forests characterized by high and continuous rainfall, with annual rainfall in the case of tropical rainforests between and metres (98 and in) and definitions varying by region for temperate monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's. Secondary forests comprise more than half of the total forest area in tropical regions and are the dominant forest type the tropics, secondary forests also represent a major global carbon sink that rapidly accumulates carbon in aboveground biomass 2,3,e they cover a large area in the tropics, accurate estimates of carbon in secondary forests are critical for quantifying the Cited by:
Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned and allowed to revert to their natural vegetation while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds. Indonesia - Indonesia - Plant and animal life: Indonesia’s vegetation is similar to that of the Philippines, Malaysia, and Papua New Guinea. There are s species of flowering plants, including 5, species of orchids, as well as the monster flower (Rafflesia arnoldii [see Rafflesiaceae]), which is the world’s largest flower. There are more than 3, tree species, including.
Abstract [Shifting cultivation is often blamed as a principal cause of deforestation in tropical Africa. It is claimed that the practice is unsustainable because shortened fallow lengths result in soils too degraded to support forest by: 7. Significant human impacts on tropical forests have been considered the preserve of recent societies, linked to large-scale deforestation, extensive Cited by:

The framework is applied in the study of recent changes in shifting cultivators’ adaptations in a lowland rainforest area in Sumatra, Indonesia. Increased rubber planting and expansion into primary forest are seen as a response to increased rubber profitability and (expected) land scarcity, and as a race for property by: Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics.
Typically it involves clearing land (often forest) for the growing of crops for a few years, and then moving on to new sites, leaving the earlier ground fallow to regain its soil fertility. Traditional shifting cultivation is not a threat for forests, even necessary for the conservation and management of Indonesian forest remnants in the future (Colfer ; Hasanuddin ).
These. Soils include podsols (spodosols), red-yellow podzolics (ultisols), latosols (oxisols) and andosols (inceptisols) as well as more complex mountain soils (Soedjito ).
Local shifting cultivation in was concentrated on andosols and latosols, with patches of old growth forest retained on podsolic soils. To understand the influence of human vs. natural fires and the historical resilience of tropical rainforest to fire, as well as the role that fire plays in carbon cycling in tropical rainforest, we are using radiocarbon dating and relative abundance of charcoal in different habitat types to examine the historical pattern of fire and pyrogenic-carbon content of soils in primary rainforest in Gunung Palung National Park (Indonesia).Author: L.

Shifting cultivation, sometimes called swidden or slash and burn, is commonly found throughout the Amazon and other tropical regions worldwide. Shifting cultivation systems are designed to adapt to the soil and climatic characteristics of the Amazon basin- low.
Shifting cultivation is the agricultural technique employed by the majority of farmers in the tropical regions of Africa. The dominant narrative recited by policy experts, non-governmental Author: Amy Ickowitz. Mackie, C., T.C. Jessup, A.P. Vayda, and K. Kartawinata.
Shifting cultivation and patch dynamics in an upland forest in East Kalimantan, Indonesia. In proceedings of a conference on “The impact of man's activities on tropical upland forest ecosystems.” pp. – Faculty of Forestry, Universiti Pertanian Malaysia, Selangor, by: Shifting cultivation supports around million people in the Asia-Pacific region alone.
It is often regarded as a primitive and inefficient form of agriculture that destroys forests, causes soil erosion and robs lowland areas of water. These misconceptions and their policy implications need to be challenged. Swidden farming could support carbon sequestration and conservation of.
Indonesia has 10% of the world's tropical forests, 60% of Asia's tropical forests, and a significant proportion of the world's remaining virgin stands. These forests are home to vast numbers of animal and plant species and people. Thus their value is substantially greater than simply their ability to produce wood and associated forest products.
Eventually a previously cultivated field will be cleared of the natural vegetation and planted in crops again. Fields in established and stable shifting cultivation systems are cultivated and fallowed cyclically.
This type of farming is called jhumming in India. Fallow fields are not unproductive. Shifting cultivation has been attributed to causing large-scale deforestation and forest degradation in tropical forest-agriculture frontiers.
This view has been embedded in many policy documents in the tropics, although, there are conflicting views within the literature as to the impacts of shifting by: Tree-planting and plantation forestry in tropical countries are expanding rapidly. Social and community forestry, tree planting to control soil erosion, and the use of agroforestry, as well as many industrial afforestation projects, are all part of the response to tropical deforestation and are central to much rural development.

Indonesia is the world's largest archipelago, consisting of s islands. It is physiologically, biologically, and culturally one of the most diverse countries in the world.
Some. “Pioneer” shifting cultivation, for example, is a system in which new areas of forest are cleared for fields, allowed to remain under cultivation too long, and then abandoned in a degraded condition (Kunstadter et al.
). In northern Vietnam, Hmong farmers have converted large areas in the highlands to grasslands as a result of pioneer by: In the tropical Americas, mature dry tropical forest is rapidly being converted to secondary forest during the fallow period of shifting cultivation.
This study addresses changes in forest biomass during forest recovery following shifting cultivation of maize (corn) in the Southern Yucatan Peninsular Region (SYPR), by: Shifting cultivation is important to many of the inhabitants of tropical forest regions.
Much scientific research has been conducted on this form of agriculture in the humid tropics, but the drier portions of the tropics remain less studied.
