inadequate rainfall has made things worse for the country. b) Scarcity of water leads to increased level of desertification: Botswana is going through severe water shortage due to inadequate rainfall and no water resource being available to tap in the land locked country. Higher and more focused efforts into the mining industry, coal extraction for electricity generation has rendered the underground water sources (the sources of portable water in Botswana) contaminated and in accessible. The…
with Pinus sylvestris to produce industrial timber. The Western concept of monocultures also developed in the 18th and 19th centuries in Europe because of the scarcity of timber,…
systems and fed in stalls, or made into silage or hay (FAO, 2015). The young leaves and shoots are edible to humans (Burkill, 1985) and considered as the second generation energy source crop in the USA (EPA, 2013). Elephant grass requires high levels of water and fertilizer. According to Francis (2004), yield range from 20 to 80 t DM/ha/year under high fertilizer inputs. With no or inadequate fertilizer, yields are in the range of 2-10 t DM/ha/year. Cuttings can be done at 45 – 90 day interval…
Water is necessary for all complex life on Earth, from plants which use its molecules to synthesize energy from sun rays, to animal cells which use water molecules to repair more complex organic structures like DNA. In addition to drinking it, humans use water for sanitation, hygienics and agricultural irrigation. The multifarious and humanitarian uses for water make it especially alarming that water privatization has sharply increased in the past decades while groundwater levels have sharply…
Water. Used all the time, in our daily lives, by every person out there. Think about how much everyone uses in just one day, now multiply that by about 7 billion. As you can see we use a lot of water on this planet and depend on it for a source for almost everything we do. But what would happen if the water just ran out? What would we do? Well in China they are facing a similar problem. China's resources are running out, more specifically Northern China. The great loss of water is effecting…
Calories A calorie is the unit used to measure the energy-producing value of food. Theoretically, calorie is characterizes as a unit of heat measurement, in nutrition and the kilocalorie is the amount of heat required to raise the temperature of 1kg water through 1˚c. Another definition is that calorie is a unit of measurement that determines the amount of heat released in a food during metabolism. It states the energy value of a food calorie (cal) or kilocalories (kcal). The body needs energy…
limestone dissolved and stalagmites and stalactites of calcite grew. Caverns continue to enlarge as salt crystals corrode rock walls. (12) During the Miocene period (23 – 5 MYA), these events led to flora and fauna which were tolerant of heat, lack of water and alkaline soil due to calcium carbonate (limestone) and limited the diversity of species seen in other biomes.…
Food is the basic need of all living creatures in the contemporary world. From humble bacteria to human beings all are striving for food since their existence. The term food security is closely related to the availability of food stuff for the existing population in the world. The concept of food security was developed formally in 1974 in world food conference. According to FAO( FOOD AND AGRICULTURE ORGANIZATION) ), food security refers to the situation when all the individuals in the…
impedes the export of other products. As a result, these countries end up importing most products leading to massive capital flight (Ross, 2007). The extraction of oil also causes environmental degradation such as global warming and massive pollution of water and…
What Is Driving China’s Water-Scarcity Crisis? What is China’s water scarcity? China has recently gone through a period of time with a lack of water. But the real mystery is what has caused the water scarcity? Let's discuss. Since China has recently gone into a water scarcity, a lot of problems have now rose such as having some of its farmable land not having water which can cause famine. There are three main causes or factors of China’s water scarcity crisis: Global Warming, Population…
