Why did Maya slash and burn stop?
The Maya of Mexico's Yucatan peninsula did not stop using slash and burn agriculture. They still use it today. Many scholars think it was the original and most common form of agriculture in the area during PreColumbian times. It was described by Diego de Landa in the mid 1500s in a book he wrote concerning Maya customs. It was also described in detail by Robert Redfield and Alfonso Villa Rojas in their book about Chan Kom, which is part of the collection of publications that came out of the Carnegie research program of the early 20th century. This agricultural system has more recently been described in Spanish by Silvia Teran and Christian Rasmussen (1994) in a book published by the State of Yucatan and DANIDA of Denmark. I also describe it in my 1998 book on Maya traditions and Mexican Rural Development. N. Bassols-Barrera and V. M. Toledo have also described it in a recent journal article.
Ideally the slash-and-burn is done cyclically, with twenty or more years of fallow between periods of two to three years of use. Maya farmers maintain that when the fallow is reduced, the yield is also reduced. However, in conditions of dense populations, farmers do not have enough land available for this cycle and thus they reduce fallow. The immediate problem of reduced fallow which has been noted by a number of researchers is weed growth. Allowing forest to grow for long periods reduces weeds (grasses etc.) on the forest floor and thus the availability of seeds that sprout and compete with the maize for nutrients when the land is cleared. The higher and denser the forest cover, the fewer weeds. Another advantage is that tree roots bring up trace minerals from the subsoil replenishing these at the level reached by maize roots. Falling leaves also contribute to soil organic matter, important for maintain tilth and soil moisture. Today, weed growth is often controlled by the application of herbicides and soil fertility is augmented by the use of fertilizers. Some weed growth is also controlled by tractor tillage.
During the 1970s and 1980s, the Mexican government introduced tractors and a version of the "Green Revolution" in those areas where the soil was sufficiently deep for tractor cultivation. Gradual compacting of soils and depletion of organic matter and changes in pH are some of the problems said to be associated with this program. Some areas cleared for tractor cultivation are no longer used for crops but rather for pasture, supplying the demands for beef and lamb among urbanites in Mexico as well as abroad.
A related issue is that in the past ten to fifteen years, the price paid to farmers for dried maize has been very low (see NAFTA). Given the costs of tractor use, hybrid seeds, herbicides and fertilisers many farmers have stopped planting in the ways recommended by Green Revolution agronomists. A few have returned to slash and burn methods, but most have abandoned farming to search for work in cities or tourist zones or in the US as agricultural workers, factory hands, or in the service sector.
Nowadays most slash-and-burn farmers are over 50, with little formal schooling and insufficient strength to be hired for construction work in cities. They provide for their families in rural communities, including their adult children and grandchildren when these are unemployed and return home. Thus, the slash-and-burn farmer is a part of the safety net of Mexican capitalism.
In addition, there are some ecological advantages to slash-and-burn. It rejuvenates forest patches and leaves a mosaic of patches in different stages of succession. These may well reduce the risk of catastrophic forest fires while helping maintain high biodiversity and thus good habitat for fauna. The impact of these fires on the local forest ecosystem has to be evaluated over time. Current government policies restrict burning, encourage mechanized agriculture and cattle raising while setting aside some protected areas for endangered species. This mix of single-purpose plots is new to the Maya forest and is an experiment. What we know to be highly resilient throughout the climate shifts of 3,000 years is Maya slash-and-burn which has not resulted in the extinction of any species of flora or fauna, to my knowledge. Although it is important to clarify that this system always included respect for certain areas of sacred forest and habitually left corridors of uncut areas between milpas of only 1 to 2 hectares. Thus forest conservation was an integral part of agriculture.
It is important to add that environmental knowledge in this area depends on use for its transfer. Farmers are also hunters and gatherers. Their wives and children participate in harvest, weeding, and gathering, and in some cases in hunting and felling brush. Gathering includes medicinal plants, plants for domestic animal use, and dead tree limbs used for cooking fires, as well as forest fruits, seeds, and roots. Farmers know the soils, which vary considerably across the peninsula. They also know well the animals they hunt and those that compete with them for their crops. In fact they plant more than they need in order to entice deer and pecarry and wild turkeys which they both feed and hunt. These are important sources of animal protein for many families. Thus, slash-and-burn is part of forest management and game management. The straight poles used to build traditional Maya houses grow best in a cleared plot allowed to fallow, not under the shade of big old trees. Palm thatch is also found in regrowing milpa plots. Regrowth occurs faster than one would imagine because the roots and trunks of trees and bushes are not removed nor are they permanently damaged by the fires. In addition, seed rain comes in from the fringes of high forest around the agricultural plots.
These are all advantages to traditional slash-and-burn which recommend it to subsistence farmers, who also tend to have traditional tastes and to not care for the hybrid maize grown with tractors and fertilizers.
As the economy has worsened, some people have left tractors and returned to slash-and-burn, as this system does not require investment in costly inputs. The harvest is free of debt. However, the biggest problem for many farmers in Yucatan today is drought and flooding, probably a result of a combination of global warming and extensive forest clearing by green revolution projects and cattle ranchers. Irrigation and drainage are critical. The regular rains of the agricultural season are now frequently interrupted by two to three week droughts which damage the forming ears of maize or kill the plants. In addition, more frequent and more intense storms are coming out of the Caribbean. These frequently flatten the maize plants in mud or rot the roots of the plants. Thus, farmers are looking more and more to irrigation systems and well drained soils. Cattle ranching has been popular but in the summer of 2009 many cattle died of hunger as there simply was not enough grass for them to eat due to the drought. Owners frequently transport water for cattle to drink during dry season but providing enough food is more difficult as droughts lengthen and spread over large areas.
Thus, the answer to this question is that the Maya continue to use their traditional slash-and-burn systems for food security despite increasing risk to all agriculture that does not include adequate irrigation and drainage. The expense of irrigation depends in large part on the depth of the water table from the surface. Drainage tends to be relatively good in the peninsula given the young karst subsoil, but the areas of flat, deep soils necessary for tractor cultivation tend to have a large percentage of clay and thus to drain more slowly than the uplands which is where traditional slash and burn is normally done.
What did the Aztecs and Mayas wear?
The Aztecs and the Mayas wore skirts made out of bamboo tree leaves. They covered their genitals with leaves.
What was the dark side of Inca Maya and Aztec kingdoms?
I think to the more civilized world we live in today it was human sacrifice, a part of there culture that we think of today as barbaric .
Tell him this: Why are you so brown? Do you ever take a bathe. Tell hime that ok hope it works
Which was not a characteristic of the Aztec civilization?
It was founded on an elaborate, hierarchical society.

Thank you
The Mayan believed all things to be linked with the divine. The Mayan creator God was known as Hunab Ku. death and Destruction were represented by the Old Woman Goddess and Xbalanque (also representing Venus and the Jaguar), and Hunapu, the Hero Twins were associated with the stars, the Sun and life. It was believed that the Hero Twins entered Xibala, the Underworld, outsmarted the death Gods and were reborn as the Sun and Venus.
The more important Maya Deities were Kinich Ahau, a Sun God, Ah Chicum Ek, a North Star God, Chac, a rain God, Itzamna, the reptile God, and Yum Cimil, a death God to name a few. All in all, the Mayan Pantheon consisted of thirteen Upper World Gods and nine Underworld Gods.
Who thought that the world would end in 2012 first?
the mayans stopped making the calander or something so now everyone is worried but i don't believe it
What did the Mayas looked like?
The Mayan ppl were short. The average height of the men was jsut over five feet. The women were about four feet eight inches tall. Mayas had straight black hair, and many painted their bodies black, red, or blue. They often had tattoos.
Why was the temple of portunus built?
The Temple Portunus was dedicated to the god Portunus in Rome. Roman Temples were used for religious ceremonies which were a matter of civic duty and obligation in Ancient Rome.
Who made the Mayan rules and laws?
they had a special calendar that sopesedly made there choises, and laws. Hope i helped:-0
P.S. it was also based on the stars!
Grupo Mayan is part of the larger company Grupo Vidanta. The founder and owner of this conglomerate is Daniel Chavez Moran, who is a real estate developer from Mexico.
Why did the Maya civilization carve inscriptions onto their buildings?
The Mayas often carved what we call 'reliefs' into the side of their architecture to tell stories. Depending on the building it could be depicting the reign of the royal family on an important temple perhaps. But on a ball court there were often reliefs depicting human sacrifice which was a common practice of the Mayas when a team lost a ball game.
In Southern Mexico and Northern Central America.
also in Yucatan.
The Mayan people were located in Southern Mexico, and near the Yucatan Peninsula. The Mayans made up the largest civilization of its time. Then mysteriously disappeared during the 8th and 9th centuries.
Why and how did the Aztecs makes sacrifices to the sun god?
They cut peoples heart out and held it up (while still beating) to the sun.
How did the Mayans empire ended?
The fall of the Maya has long been one of the great mysteries of the ancient world. But it's more than a historical curiosity. Within sight of the Mayan ruins, in the Petén region of Guatemala near the border with Mexico, the population is growing again, and rain forest is being cut to make farmland. http://wiki.answers.com/mailing-lists/subscribe/
"By learning what the Maya did right and what they did wrong, maybe we can help local people find sustainable ways to farm the land while stopping short of the excesses that doomed the Maya."
From pollen trapped in ancient layers of lake sediment, scientists have learned that around 1,200 years ago, just before the civilization's collapse, tree pollen disappeared almost completely and was replaced by the pollen of weeds. In other words, the region became almost completely deforested.
Without trees, erosion would have worsened, carrying away fertile topsoil. The changing groundcover would have boosted the temperature of the region by as much as 6 degrees, according to computer simulations by NASA climate scientist Bob Oglesby, a colleague of Sever at the MSFC. Those warmer temperatures would have dried out the land, making it even less suitable for raising crops.
Rising temperatures would have also disrupted rainfall patterns, says Oglesby. During the dry season in the Petén, water is scarce, and the groundwater is too deep (500+ feet) to tap with wells. Dying of thirst is a real threat. The Maya must have relied on rainwater saved in reservoirs to survive, so a disruption in rainfall could have had terrible consequences.
