Both drought and poverty have countless repercussions and consequences worsening the quality of life for many. Inadequate sources of water increase poverty by limiting agriculture, creating famine, and enabling the spread of diseases. Lack of water contributes to poverty by inhibiting the availability of agricultural products. For Instance, the Institute for the Study of Society and Environment (ISSE) wrote an article concerning the aftermath of droughts. The article started off by reporting that “because most Sub-Saharan economies are driven primarily by agriculture, the effects of meteorological droughts are direct and can be large.
The political factors include weak governance, the destabilizing influence of outsiders, extra-legal criminal networks with vested interests, and the role of armed forces, including the UN, the military, and the police. Economically, the lack of public goods and community organization, high unemployment rate, economic inequality, and unfavorable terms of trade are all limiting factors. Environmentally, current natural disasters, environmental degradation dating back to the colonial era, unfavorable topography, and massive deforestation are all challenges for Haiti. (Webersik
The situation of disaster in Viet Nam Vietnam is one of four countries which has a big impact of harsh weather phenonmena in recent two decade . In each year of Vietnam, there are 466 people died and lost over 1.5 million USD equal to 1.5% of GDP. In addition, nowadays, the development of disaster become more complex without any stability. The appearance of disaster is increasing with the strong intensity especially Vietnam is the country suffer the impact of climate change. In 2012, East Sea occured 10 typhoons and 2 tropical depression in which have 4 flood impact directly in Viet Nam.
More than 50% of the area under wheat cultivation is affected by periodic drought (Rajaram, 2001; Pfeiffer et al., 2005) and it has become one of the main environmental threats to grain production especially the arid and semiarid regions of the world and ultimately to global food security (Chaves et al., 2003). In major wheat-growing areas of the world, particularly with a Mediterranean climate, mean pan evaporation often surpasses average precipitation especially during grain filling, leading to drought during reproductive and grain-filling phases, which is also known as ‘terminal drought’ (Reynolds et al., 2005a). It comes in to play with heat stress. Exposure to higher than optimum temperature reduces yield and decreases the quality of wheat ( Fokar et al., 1998;Maestri et al., 2002;Wardlaw et al., 2002). Amongst all phenological stages in wheat reproductive and grain filling stages are most sensitive ( Pradhan et al., 2012) and results in substantial yield losses.
Presently, the Philippines is confronting serious negative results of the unwanted adjustments in two seasons. During the dry season, it is noticeable that the gradual increase of surface temperature that leads to El Niño affects the country 's various sectors such as water resource from dams, agricultural productions, and human healthcare. The most widely recognized impact of El Niño is drought and reduced rainfall that may last a year. For instance, last May 2015, Angat Dam, the supplier of 97 percent of Metro Manila 's local water needs, breached its 180-meter minimum operating level due to the lack of rain over the Bulacan watershed. Consequently, agricultural productions were affected when the dam shutdowns farm irrigation after it reached 179.67 meters bringing about the loss of crops additional operational cost.
Altogether, overcrowding negatively affects the environment. Overpopulation causes habitat loss, increases the rate of extinction, decreases the amount of fresh water available, and limits natural resources. Overpopulation has damaged many diverse ecosystems throughout history. As the
There are so many reasons to expose landslide risks like high poverty, increasing deforestation, bad agricultural practices in hill and sloppy area and lack o f public awareness. The vulnerable groups such as poor people, women, children , the elderly and people with disabilities have the minimal adaptive capacity to bear the risk (few, 2003, ICIMOD, 2012). In Nepal, landslide and floods directly affect to the people about 260 people are died and 30,000 families are affected in each year. There has been an average loss about 788 million Nepalese Rupees due to natural disaster ( Bhandary et al, 2013). Also, 2 percent of GDP is lost every year by a major disaster in Nepal.
Water and change report Water scarcity is the deficiency of available water resources to meet the demands of water use within a specific region. The water scarcity apparently affects around 2.8 billion people, which means that more than 1/3 of entire human population live under water-stress condition. However, by 2025 2/3 of the world population will be living under water-stressed conditions. Locations of Water Scarcity From the map above it can be seen that the water scarcity can be divided in two parts, physical water scarcity (red) and economic water scarcity (yellow). However, some regions have little or no water scarcity (blue) or approaching physical water scarcity (orange).
One of the vastest issues the country is facing during the recent years is climate change. This change occurring in the climate has an impact on the natural phenomena like changing rainfall distribution and temperature, to name some. It is a fact that annually, 20 tropical cyclones enter the Philippine Area of Responsibility (PAR), on the average. Among the total tropical cyclones, not all are developed to become a strong typhoon, which brings disasters and serious destruction to the environment that severely affects humans. The disasters being described are forest fires, soil erosion, flooding, etc (ERDB 2011).
Introduction Background of the Study Floods are surrounded by earth’s most common and destructive natural disasters. It can cause many problems and take lives as well. Due to a heavy rainfall, people need to prepare for the possible floods and landslides in several parts of the country, that’s why in the Philippines it’s a major problem because the country is prone to natural disasters particularly typhoons, floods, earthquakes, landslide, etc. The Philippines is in the fourth most disaster-prone country in the world with a total of 274 natural calamities over the past two decades. It is according to a study “The Human cost of Weather Related Disasters” conducted by Geneva-based United Nations Office for Disaster Risk Reduction (UNISDR) and
