The History and Domestication of Cassava

Cassava (Manihot esculenta), also known as manioc, tapioca, yuca, and mandioca, is a domesticated species of tuber, a root crop originally domesticated perhaps as long ago as 8,000–10,000 years ago, in southern Brazil and eastern Bolivia along the southwestern border of the Amazon basin. Cassava is today a primary calorie source in tropical regions around the world, and the sixth most important crop plant worldwide. Fast Facts: Cassava Domestication Cassava, commonly called manioc or tapioca, is a domesticated species of tuber, and the sixth most important food crop in the world.  It was domesticated in the southwestern Amazon of Brazil and Bolivia some 8,000-10,000 years ago.  Domesticate improvements include traits which must have been added by means of clonal propagation.  Burned tubers of manioc were discovered at the classic Maya site of Ceren, dated to 600 CE.   Cassava Progenitors The progenitor of cassava (M. esculenta ssp. flabellifolia) exists today and is adapted to forest and savanna ecotones. The process of domestication improved the size and production level of its tubers, and increased the photosynthesis rate and seed functionality, by using repeated cycles of clonal propagation—wild manioc cannot be reproduced by stem cuttings. Archaeological macro-botanical evidence of cassava in the little-investigated Amazon basin has not been identified, partly because root crops do not preserve well. Identification of the Amazon as the point of origin was based on genetic studies of cultivated cassava and all various possible progenitors, and the Amazonian M. esculenta ssp. flabellifolia was determined to be the wild form of todays cassava plant. Amazon Evidence: The Teotonio Site The oldest archaeological evidence for manioc domestication is from starches and pollen grains from sites outside the Amazon.  In 2018, archaeologist Jennifer Watling and colleagues reported the presence of manioc phytoliths attached to stone tools at the southwestern Amazon Teotonio site in Brazil very near the Bolivian border. The phytoliths were found in a level of dark earth (terra preta) dated to 6,000 calendar years ago (cal BP), 3,500 years older than any terra preta anywhere else in the Amazon to date. The manioc at Teotonio was found alongside domesticated squash (Cucurbita sp), beans (Phaseolus), and guava (Psidium), indicating that the inhabitants were early horticulturalists in what is becoming recognized as an Amazonian center of domestication. Cassava Species Around the World Cassava (Manihot esculenta), root and ground for dinner.   Rodrigo Ruiz Ciancia / Moment / Getty Images Cassava starches have been identified in north-central Colombia by approximately 7,500 years ago, and in Panama at Aguadulce Shelter, about 6,900 years ago. Pollen grains from cultivated cassava have been found in archaeological sites in Belize and Mexicos Gulf coast by 5,800–4,500 bp, and in Puerto Rico between 3,300 and 2,900 years ago. Thus, scholars can safely say that the domestication in the Amazon had to happen before 7,500 years ago. There are numerous cassava and manioc species in the world today, and researchers still struggle with their differentiation, but recent research supports the notion that they are all descended from a single domestication event in the Amazon basin. Domestic manioc has larger and more roots and increased tannin content in the leaves. Traditionally, manioc is grown in the field-and-fallow cycles of slash and burn agriculture, where its flowers are pollinated by insects and its seeds dispersed by ants. Manioc and the Maya The Pompeii of North America, Joya de Ceren, was buried in a volcanic eruption in August 595 CE. Ed Nellis Members of the Maya civilization cultivated the root crop and it may have been a staple in some parts of the Maya world. Manioc pollen has been discovered in the Maya region by the late Archaic period, and most of the Maya groups studied in the 20th century were found to cultivate manioc in their fields. The excavations at Ceren, a classic period Maya village that was destroyed (and preserved) by a volcanic eruption, identified manioc plants within the kitchen gardens. Manioc planting beds were discovered some 550 feet (170 meters) away from the village. The manioc beds at Ceren date to approximately 600 CE. They consist of ridged fields, with the tubers planted on the top of the ridges and water allowed to drain and flow through the wales between the ridges (called calles). Archaeologists discovered five manioc tubers in the field which had been missed during harvesting. Stalks of manioc bushes had been cut into 3–5 foot (1–1.5 meter) lengths and buried horizontally in the beds shortly before the eruption: these represent preparation for the next crop. The eruption occurred in August of 595 CE, burying the field in nearly 10 ft (3 m) of volcanic ash. Sources Brown, Cecil H., et al. The Paleobiolinguistics of Domesticated Manioc (Manihot esculenta).

The Effects Of Poverty On The Health Of Populations Essay

The Significance of Poverty Poverty plays a big role in determining how well a person will live. Poverty affects almost half the world, in which over three billion of the world population â€Å"live on less than $2.50 a day† (Shah, 2013). Even if the $2.50 was exchanged to the currency rate of a given country, the amount will not be sufficient to live on. Poverty is so detrimental that â€Å"22,000 children under five still die each day† (UNICEF, 2010). Living in poverty reduces the quality of life to almost nothing, which no human being should ever have to experience. Compared to adults, children are most affected by poverty because they are more fragile. Poverty causes many deaths which will decrease the world population. Children are the future in this world. If more children begin to die from poverty, then there will be no future for the human race. Causes and Impacts of Poverty on the Health of Populations National Debt Many third world countries have massive debt due to loans from international financial institutions such as World Bank and International Monetary Fund. The loans that these countries make are supposed to help them reduce their debt, but in some cases, they do not. According to Jubilee Debt Campaign, a charity who focuses on the liberation of poverty in third world countries by advancing education, â€Å"for every $1 received in grant aid, low income countries way $2.30 in debt service†.

Time VI Conclusion-Recommendation Even though the government has to invest money in educational process, the last solution is the best because it has the advantages of the other alternatives without major disadvantages. Therefore, I recommend that the Kazakh society should keep in mind that the important strategic objective is to preserve the traditions of the Kazakh culture for future generations and increasing the cultural values of the city. In the meantime, I suggest the government immediately take the measures by supporting the society and creating new opportunities to develop the ulture of Kazakhstan. By being responsive to the citizens, government in essence would try to unite with them for the success of their purpose to raise the cultural development of the country. The total well being and lifestyle potential of population in many cases determined by stage to train and learning and social stage of people, their background knowledge and perspective growth, and by available opportunity to receive and use required information. These factors determine whether city community is involved in local, national and international process of civil growth. Ways to train and learning, ethical concepts and useful accessibility are the main features of religious and possible development. Thus, development of viewpoint system to train and learning, social and useful growth are the most important in growth of country. Due to decline of the cultural development in Kazakhstan the government and the society should take definite and urgent measures to improve the situation. â€Å"One of the main success of the period of freedom is rebirth and further growth of the Kazakh lifestyle and the societies and customs of social categories existing in Kazakhstan. The growth of the Kazakh lifestyle promote socio-cultural and ethical regrowth of community as a whole, as well as growth of social categories located in Kazakhstan, the building up of worldwide interaction. In the years of freedom have created a multitude of cultural and social facilities, art groups.. †(Kornilov,2011). Exclusive lifestyle and unique spirit of understanding and information of life which were provided to us as a heritage of this wide area of Kazakhstan by our ancestors. This sense of independence and valor of the steppe was not lost on different periods of history, it andled to keep by the past generation, who have been through tragic obstacles. And hundreds of years of desires and ambitions of our forefathers came real. Kazakh community believes that, Kazakhstan becoming a birthplace of many projects in the area of lifestyle and artistry. â€Å"For example, learners of Almaty Choreographic University confirmed their abilities in the United States and Switzerl and, the Korean National Music and Drama Theatre took part in an worldwide ethnic event in the Republic of Korea, and numerous activities were organized in other countries, devoted to the performs of Abai. †(Kornilov,2011). Although â€Å"Kazakhstan finalized the contracts on cooperation in the area of lifestyle from 49 nations of the near and far overseas. †(Kornilov, 2011). However, Kazakhstan has many issues to fix, especially worried social growth. Despite that fact that while preserving kazakh heritage, Republic of Kazakhstan shows keeping with the speed of contemporary high culture and to kazakh art employees praised most of all judges all over the world, the present younger people only just taking the first actions to achieve success praising their native country in the future. The first possible solution is to raise the intellectual development by advertising the books, articles, journals etc. , if to be exact-to make them fashionable. The main way of upbringing the population, particularly children, adolescents and young people, striving for intellectual development is the formation of a unified and accessible to every citizen of the educational space of the city, providing technological, logistical and financial resources, promoting libraries and book stores creating conditions for the citizens of modern education in accordance with their needs. The greatest advantage of his solution is that young people’s background knowledge may become improved and wide because of new technologies and free access area created. Another advantage of raising the intellectual development is mastering achievements in domestic and world culture. By this, I mean that citizens of Kazakhstan seem to pay more attention on what have been reached on cultural level, especially domestic. The last advantage of this solution is that young people of Republic of Kazakhstan could receive modern educational equipment like hi-tech libraries, free access internet resources etc. These ducational tools are likely to help young generation achieve more success in their studies. The greatest disadvantage of the first solution would be financial difficulties that government or Kazakh society could ever face. Another disadvantage have occurred because of the difficulties of the organizational process, to be exact, the establishing the cultural events and hiring workforce. One of the suggested solutions is to increase cultural valuables and saving cultural heritage for future generations. For example, observe the monuments and memorial s, decrease the price of tickets for theatre and museum visiting. All these method should definitely help with governmental support. Reducing the level of culture, dangerous in itself, because it creates spiritual lack and causes the loss of completeness and quality of life, it is unacceptable for the transition to sustainable development, since it violates the principles. Therefore, an important strategic objective is to preserve the traditions of Kazakh culture for future generations and increasing the cultural values of the city. One of the main advantages of the solution is discovering new talents. There are many ways to ind talented people like annual competitions among school children and youth on the best research on the cultural history of the city, systematically lead the campaign to restore the historic, cultural and moral traditions in Kazakhstan, establish a fund supporting young talents. Moreover, there is definitely should be governmental support which may lead to better comprehension between society and administration. However, there are still disadvantages are included unfortunately, one of them is cost because the cultural heritage has to be protected and saved, and there simply should be finances to rovide the expenses. Another disadvantage is that intrusion into the cultural market economy has led to a noticeable decrease in the quality of commercialization and cultural life, in which the rule passed to popular culture. Free profit in culture dramatically reduced intellectual and moral standards of its mass perception, put the property in line with consumer goods are. There was a dominance of low-grade and low-grade commercial foreign films on television advocating violence, corruption, lack of spirituality, the book market appeared dubious literature, from the repertoire of theaters as washed out and a real classic domestic drama, in art the main place was kitsch. Thus, the culture fully experienced the negative effects of the economic crisis, social and political instability, activation of destructive forces in society. Finally, the third possible solution is to creating conditions for receiving general and special education. Young people and the city’s population as a whole has recognized the importance of education for progress and success in life. Young generation desire to find a prestigious profession, noted the desire to develop their personality, to find ositions in society, to gain the respect of folks. The greatest advantage of this solution is that not only in Kazakhstan, but mostly in all countries, general and special education happen to be very beneficial, because those people who have received general and special education become more or less educated, they have fundamental knowledge. Another advantage is that children likely to be more educated because of new educational environment and new interests in study that adoles cents would be excited. The greatest disadvantage would be still the financial part, because for each sphere of ducation should be allocated some amount of money for providing better educational system. But allocation of money still cannot be done appropriately because of many factors such as corruption, negligence etc. Also, the creating of new conditions for receiving general and special education would may take some time because creating includes innovations in educational system, new buildings, more equipment and so on. According to John Heywood (n. d. ) â€Å"Rome wasn’t build in a day†. Although the increasing the cultural valuables and saving the cultural heritage would be he most convenient, the solution of creating conditions for receiving general and special education is the most feasible. Even though the government has to invest money in educational process, the last solution is the best because it has the advantages of the other alternatives without major disadvantages. Therefore, I recommend that the Kazakh society should keep in mind that the important strategic objective is to preserve the traditions of the Kazakh culture for future generations and increasing the cultural values of the city. In the meantime, I uggest the government immediately take the measures by supporting the society and creating new opportunities to develop the culture of Kazakhstan. By being responsive to the citizens, government in essence would try to unite with them for the success of their purpose to raise the cultural development of the country. Reference list: Kornilov I.
