Weather and Climate
The village of Dokur is drought prone and represents the semi-arid tropics. The annual maximum temperature in summer, March till June, in the village is around 45°C, while the minimum temperature is 20° C. The winter, October till February, are pleasant in means of temperature, which lie between the 13 and 30°C. July till September is the tropical rain season. The state of Andhra Pradesh receives a high amount of rainfall during this period of time, although the amount of rainfall has been decreased over the years. For about a third of the rainfall is brought by the North-East Monsoons. The normal rainfall in the village is 730 mm, distributed erratically. Uneven distribution of rainfall is affecting critical stages of crop cultivation have become commonplace in the recent years.
Water is essential to transport the nutrients. If there is a lack of nutrients the leaves will turn yellow, and will no longer be able to support the transpiration process of the crop. The vesicles, which the crop uses for transpiration, will become clogged and the crop will get damaged due to overheating. The climate of the state Andhra Pradesh, where the village Dokur is located, is generally hot and humid. The factor determining the climate of the state is played by the South-West Monsoons.
The graph, figure 3, illustrates the monthly rainfall in millimetres over a period of time that has been measured form 1975 until 1981, and then from 2005 until 2008. The graph shows that the rain season is disrupted over the years. Not only the amount of rainfall, significantly decreased, also the period of time in which rain falls in high percentages has changed.
Usually the rain season (the monsoon), takes place...

... the land throughout the village. Eight of these bore wells are used for drinking water and sanitation purposes. The village has access to water throughout the year, but it has to cope with the fact of water becoming scarce.
Fertiliser and pesticides
Fertilisers and pesticides are not available in the village itself, although it is available in the nearest town. The adoption of hybrid and improved seed technologies, the use of chemical fertilisers and plant protection measures, mechanization (use of tractors, sprinkler irrigation and power sprayers) and soil and water conservation measures, have been contributing significantly, to increase farm productivity. Genetically modified seeds have been adopted in the village, including Sona Masuri and Hamsa in paddy, GCH-4 in castor and LRG-11, LRG-41, PRG-158, ICPL-87119, ICPH-2671 and ICP-8863 (Maruti) in pigeon pea.
In an argument, the lawyer representing Monsanto Company stated that the amount of arable land around the world is quickly dwindling. This means that it is time to take extra drastic measures to improve food safety throughout the world. Genetically modified seeds and related chemicals offer the best solution for such food safety concerns and thus the company was right to make such investments. This idea comes from recent realization of a robust population boom throughout the world, an inability for traditional agricultural practices and seeds to withstand changing climatic systems. Modification of the seed’s genetic material to withstand climatic and other environmental threats seems to be a viable solution to the challenge.
Land preparation for farming and animal rearing was done using a method called girdling – tree killing. They will cut around each tree to stop nutrient from getting to the tree and the leaves will later felled down. They will now come back and cut the branches of the trees and burn the underbrush. Farmer starts plowing as the trees stumps decays and stones will be removed from the fields. Fields for farming are always small because of labor and there are boundaries between fields and the neighbors. The house or the farm was viewed as the workplace. And land given out to each family will be fenced to stop cattle from wandering off going into the farm areas. The land allocated to each family will show the family social status within the community. The towns developed individually and community involvement was given a great significant although the community was close knit.
A debate is ragging over the advancements being made in genetic engineering. Scientist discovered that genes are the map of every aspect of a living organism, this has furthermore led to the prospect of altering this coding. By modifying one’s genes parents will one day be able to pick the color of their unborn child’s eyes and farmers will have the ability to develop plants that will produce bigger and healthier harvest. With the growing anticipation that some feel towards genetically modified crops others question it effects on the surrounding environments. Often pesticides are more heavily relied on for genetically modified crops and some cases have found pollination decreased in areas dominated by GM plants. Since there are so many aspects of genetic modification that have yet to be explored, much more research is required before distributing GM seeds internationally, but from the information already available the sides have begun to divide.
Climate change is currently generally regarded as a major global issue that is especially acute in developing countries. This study focuses on the impacts of climate change and variability on smallholder farmers, their vulnerability and coping strategies on a micro-scale in a developing country.
The weather in this novel controls their crops and the river flow; which controls their food and water supply. They depend on adequate rainfall to help their crops to grow and for the river to be full. They also depend on the sun to warm things up and make the crops grow. However, if there is too much rain or too much sun it can cause many problems, such as a drought or a flood. These things are significant in this novel, because t...
With an ever increasing world population, massive third world hunger, and with an estimation that a child dies for every two seconds world-wide from starvation; this does not even take into account the number of people who are mal and undernourished, there is a great promise in the use of this technology to benefit not only the farmers, but also societies worldwide. We have been able to genetically modify plants so that they may be more resistant to insects, so that there is less pesticidal toxins sprayed. We have designed plants that require less water, less soil nutrients, preserving precious recourses. We have designed plants with higher yield, shorter seasons, plants that need less land to grow; we are said to be living in a time where we have the healthiest, most well-tested plants in the history of this
...creased rainfall and increased temperature in the western part of Central Asia such as Uzbekistan and Turkmenistan leading to the scarcity of water which directly heats the agriculture and livestock production. The estimating consequences from the precipitation and temperature change on the production of food are the potential changes in variability and extreme events like droughts, heat waves, sand storms and heavy rainfall. Increased surface runoff in the mountainous regions accelerates the land slides, soil erosion and floods which have huge capability to destroy the crops.
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.

Genetic engineering enhances plant resistance to drought, salinity, disease, pests and herbicides. The aim is to try and enhance the growth, productivity, nutrient value, and chemical composition of the plants. Chemicals are constantly being developed or improved to enhance the competitiveness and adaptability of crops, and to kill the parasites and weeds which plague the agricultural sector. . This however is not always good as the plant and the pests then become resistant to these new chemicals defeating the purpose of it being used. The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the so...
The global population in the year 2050 is expected to be nine billion and the agricultural demand is expected to double. With the current population already over seven billion people, there are hunger issues all around the world (“New” par. 1). How are we going to deal with food shortages in the future? With less land to work with, strains on the soils, and the lack of water, it is getting harder for the farmers of the world to support our growing population. These complications are making it harder for farmers to produce quality, affordable food. To help the crops grow better, farmers use fertilizers and chemical sprays to enhance growth and control the weeds. Farming in the United States is a relevant business because it supplies people with food, provides people with jobs maintaining the used equipment with the new equipment being much more expensive, and it provides research for more efficient ways on how to feed the world.
Drought is a difficult thing to measure, mainly because of all the different factors that are involved when determining the kind of drought, its intensity, and the length of the drought. Because drought can be defined in many different ways by many people, these are the three most frequently used: Meteorological, Agricultural, and Hydrological drought (What is Drought, n.d.). A Meteorological drought is typically defined by the degree of dryness and the span of the dry period. Agricultural drought focuses on the precipitation shortages, soil water deficits, and reduced ground water or reservoir levels needed for irrigation. The Hydrological drought occurs after periods of continuous lack of precipitation that reduces the water supply, impacting the community (What is Drought, n.d.). When determining whether the drought is short...
Since 1960s both minimum and maximum temperatures have exhibited a rising trend; with minimum increasing by a range of 0.7-2.0 degrees Celsius and maximum by 0.2-1.3 degree Celsius varying by region and season. Notable also is variability of rainfall patterns such as below normal rainfall in the long rains season and more during the short rainfall season, some regions have recorded more intense rainfall and downpours that have resulted to floods and infrastructural impairments. Extinction or near extinction of flora and fauna, changes in flowering and maturity patterns in crops are all attributable to climate change. These changes have had and are expected to have far reaching impacts on the economic sectors of the economy. Some of the expected sectoral impacts are discussed
The tropics are effect by many weather conditions which makes the jobs of farmers difficult. Overall subsistence and the GNP are effected by changes in weather, which for the most part is not always predictable. In a world that is divided up into the haves and the have nots, government influence is crucial in regulating practices and the overall distribution of wealth Despite this fact, programs implemented did not always succeed in benefitting the Filipinos. One major attribute of the Philippines is the wide variety of crops produced in this region. Crops which many not be able to grow during the rainy season may grow during in the period of December - May when there is little rainfall (and vice versa).
Organic farming has mushroomed drastically in importance and influence worldwide from its modest beginnings in the first half of the last century. Organic farming is production of food and livestock without the use of herbicides, pesticides, weedicides, fertilizers or genetically modified organism and use natural resources such as manure and compost instead. In other words, it is a production system which maintains the quality of soil ecosystem as well as human beings. According to IOWA State University, “the chemicals were not used for farming before World War 2. A number of munitions used in farming have contributed to field of agriculture. For instance, ammonium nitrate used as ammonium nitrate fertilizer”.
