Stress reactions after a disaster look very much like the common reactions seen after any type of trauma.


How do natural disasters affect agriculture?

The number and frequency of recorded natural disasters, along with the associated impact and damage to livelihoods and economies (local and national), are increasing significantly. Natural disasters often destroy critical agricultural assets and infrastructure, disrupting production cycles, trade flows and livelihoods means. This affects food security and causes additional disruptions throughout the value chains. Such disasters may slow overall economic growth, especially where agriculture and food production still account for a large share of gross domestic product and employment. Notwithstanding the many efforts at national and international level, there is limited systematic data and information on the impact of disasters and hazardous events in agriculture and its subsectors – crop, livestock, fisheries, aquaculture and forestry. Caribbean and Central America North Africa and Western Asia South America South Asia Linear Trend


How does FAO impact agriculture?

How do natural disasters affect agriculture?

In the case of agriculture, the direct and positive impacts are actually readily identifiable. Typhoons increase the supply of water for agriculture as they usher in rain. Floods improve soil fertility as they deliver nutrients from the uplands to the lowlands. In addition, floods temporarily create a larger water habitat for inland fish and other aquatic animals. Together with other yet-to-be-identified factors, these impacts of typhoons and floods are viewed as positive because, ceteris paribus, they facilitate an increase in agricultural production in the affected areas and help improve the food security situation.


What is a natural disaster?

From an economic perspective, a natural disaster can be taken as a natural event that causes a perturbation to the functioning of the economic system, with significant negative impact on assets, production factors, output, employment, or consumption (Hallegatte and Przyluski, 2010).


How does drought affect marine ecosystems?

As well as negative aboveground effects, droughts also tend to negatively impact marine ecosystems. Rising temperatures coupled with the rising carbon dioxide levels in the atmosphere cause coral reef bleaching, or the chalky appearance coral takes on when it dies (MO-COMSTE, 2010). The destruction of coral reefs reduces marine biodiversity which is critically important for the ecological balance and productivity of marine ecosystems. It has been reported that the El Niño episode which occurred in1997 and1998 in the Philippines, decreased the coral cover ranging from 46% to 80% in Bolinao, Pangasinan (GOP, 2010). Other areas affected included Batangas, other parts of Northern Luzon, West Palawan, and parts of the Visayas. In addition to droughts, floods could inundate mangrove, coral reef and sea grass areas along the coast, making them less viable as important providers of ecosystem goods and services to both the economy and environment.


What are the natural resources in the Philippines?

The natural resources sub-sector of the Philippines includes land, forest and fisheries resources while the natural environment sub-sector refers to the quality of its land, water and air resources. In general, the natural resource and environment sector is facing the twin problems of overexploitation and depletion of natural resources and the deterioration of the overall environmental quality. In recent years, little progress has been made in arresting the worsening pace of these problems even as new challenges have emerged (EC, 2009).

Do typhoons affect food security?

Hence, based on food affordability alone, these disasters may have little effect on food security at that level. On the other hand, it was also estimated beforehand that typhoons have a significant and negative effect on rice production at the provincial level. Therefore, based on rice availability alone, typhoons may have diminished food security at that level.


What are the three factors that affect California agriculture?

Three unpredictable factors that continue to significantly impact California agriculture production are labor shortages, access to high-quality water, and wildfires.


What are the priorities of California agriculture?

Water quality and quantity are top priorities in California agriculture. Over 50 percent of the state’s population are experiencing abnormally dry areas, with 4 percent currently in a drought. 2018 revisions to the Clean Water Act would erase protections for ephemeral or intermittent waterways that only flow after precipitation. This lift on federal protections would allow growers more freedom to use the resources on their land in the fullest capacity, but proper education about water and soil sustainability is imperative to maintain proper water quality for future generations. The Natural Resources Conservation Service (NRCS) works to provide farm operators who implement conservation strategies with technical assistance and financial incentives. Other organizations, like the Water Foundation, are committed to educating and enabling the community with innovative approaches to provide lasting water solutions that work for the communities, economies, and environment in California. Proposition 1 of the Water Bond allocates $7.5 billion to aid in water conservation efforts like groundwater storage, watershed protection, flood protection, and water restoration to combat the effects of California droughts.


How many acres of land burned in California in 2019?

In 2019 alone, there were 7,860 fire incidents resulting in 259,823 acres burned. This was relatively low compared to the 1,963,101 acres burned in 2018, mostly due to the record-breaking Mendocino Complex Fire. The California Department of Forestry and Fire Protection (CAL FIRE) predicts fire potential to be above normal for 2020 as a result of high offshore winds. Wildfires can also trigger other negative consequences like power outages and mudslides that further devastate farmlands, livestock, and crops.


How do natural disasters affect food production?

As the previous examples indicate, a natural disaster interferes with the food supply chain at every level, starting with agriculture. When a catastrophe occurs, the physical damage sustained directly by the agriculture industry alters the entire supply chain.


What are the risks of natural disasters?

Pathogens represent a massive risk in food quality and safety. One of the most significant impacts of a natural disaster is the increased risk of contamination from raw materials utilized in food processing. Front line defense against food contamination often comes from farmers and growers of the food and ingredients. However, relying on them entirely in the event of a natural disaster can expose your facility to undue risk.


How many people died in a natural disaster between 1970 and 2015?

An incident is declared a natural disaster when it’s an earthquake, storm, flood or heat wave that results in 10 or more deaths or affects more than 100 people.


How does transportation damage affect food?

Transport damage: When a road gets washed out or a tree falls across a railway track , that delay has a domino effect throughout the food supply chain. In some cases, the communication systems used to coordinate transportation are not functional either, causing chaos and problems to ensue. A breakdown in transportation due to a disaster can lead to foods and ingredients spending longer than they should in transport and possibly being exposed to a temperature range between 40 and 140 degrees Fahrenheit, which is commonly considered the “danger zone” for many food products because those temperatures allow increased growth of microbes that are potentially harmful. As a processor, the impact of transport damage increases the need to be vigilant about the possibility of contamination to food products.


What is the front line defense against food contamination?

Front line defense against food contamination often comes from farmers and growers of the food and ingredients. However, relying on them entirely in the event of a natural disaster can expose your facility to undue risk. Legislative requirements dictate common food safety standards and protocols.


Why is it important to train employees before a disaster?

The need for adequate training before a disaster strikes is important to maximize employees’ ability to perform sufficiently when a natural disaster does occur.


What is infrastructure damage?

Infrastructure damage: Destruction or damage of necessary agricultural structures often results in issues stemming from a reduction in quality control. For example, when irrigation systems fail they compromise the quality of any remaining crops. If a refrigerated storage facility experiences extended power outages, they often lose entire lots of product. If a flood breaches a livestock facility, it can result in the animals drowning or being exposed to a host of pathogens. Infrastructural damage usually means food producers must pay even closer attention to the source of their raw materials and act quickly to identify the possibility that pathogens have a higher potential to enter the food supply chain due to the effects of a natural disaster.


How does natural disaster affect food security?

Hunger and other types of malnutrition continue to impact millions of people across the world. Natural disasters pose a short–term threat to food security, as well as a long–term threat to economic growth. The overall output of food grains drops as a result of a natural catastrophe. It causes a food shortage in the influenced regions. Food security is a critical public health concern during a disaster because total food grain production is severely impacted. We need a well-functioning food system for everyone to obtain adequate proper food stock during such natural calamities as these are unavoidable, and no one can stop them, but the government can prepare the country for the consequences.


Why are farmers more vulnerable to economic downturns?

Farmers in rural areas are more vulnerable to economic downturns because they rely heavily on natural resources and have no other source of income or employment. Farmers’ crops will be harmed by natural disasters, and they will be unable to sell them at a good price. When landlords are unable to sell their crops at a good price, they will make less profit, and in order to increase their profit, they will hire fewer farmers. This will result in increased unemployment in the agricultural sector, lowering Marginal Labor’s income. Thus, unemployment will rise, resulting in a decrease in people’s earnings. This will exacerbate national inequalities as well.


Why is agriculture important?

Agriculture is the major source of livelihoods and food security in many of the nation’s most vulnerable to natural catastrophes, as well as a significant engine of economic growth. High production losses in medium- and large-scale catastrophes can lead to increased imports of food and it resulting increased public spending to end hunger and food poverty, as well as to construct sustainable, affluent futures.


What are the consequences of famine?

Famine is an inescapable circumstance wherein an enormous number of individuals in a nation or locale need admittance to a suitable food supply. Malnutrition, hunger, illness, and a high death rate are all consequences of famines. A famine can be caused by a natural disaster, such as prolonged drought, flooding, extreme cold, typhoons, bug infestations, or plant disease, in combination with government decisions on how to respond to the crisis. A natural calamity might start a famine, and a government’s incompetence or reluctance to cope with the repercussions could amplify the impact. If a natural disaster strikes a large region or occurs over a lengthy period of time, it may result in starvation. When crops or food distribution facilities are destroyed as a result of a natural catastrophe, it has a significant impact on the availability of food in the surrounding area which later becomes starvation.


How is subsidized grain distributed?

Subsidized grain is distributed through a public distribution system to individuals living in poverty.
