Agriculture is the backbone of a stable nation, but it can also be an engine of climate change. It can cause prolonged droughts, violent floods, health related issues for employees and sea level elevations.
The biophysical environmental conditions such as pulse and press events can influence the types of adaptive management that farmers choose. However, results suggest that farmer identities and values play a smaller role in shaping these decisions.
Agriculture is a critical economic sector for any country. It provides food for its people, fuels a nation’s exports and is the source of jobs that are vital to local communities. Dhanlaxmi Bank Platinum Credit Card Review in 2023 However, this industry is sensitive to weather patterns and climate changes. This is especially true in low-income countries that depend on specific climate conditions and natural resources to support their economies and the lives of their people.
While gradual changes in temperature and carbon dioxide could increase crop yields, extreme events can also negatively impact them. Droughts, flooding, sea level elevations and natural disasters can devastate crop production, leading to famines and rising food prices.
Moreover, climate change can cause soil to become less fertile and create nutrient imbalances that reduce crop yields. In addition, the timing of frost and other weather events can impact crop growth. For example, late frosts can delay seeding and flowering and affect yields for some tree fruit crops.
Developing nations are particularly vulnerable to the impacts of climate change, which can include droughts. These events can create water and food insecurity and exacerbate pre existing problems such as famine and civil unrest. Furthermore, they can disrupt the global economy by affecting food transportation systems. If you need essays like this you can search for essay writing service providers.
Droughts are triggered by a lack of rain, and they can affect a region’s soil moisture level by influencing the balance between the amount of water gained from rainfall and the amount lost through evapotranspiration. A variety of factors affect this balance, including temperature, sunshine, wind and the water vapour already in the atmosphere.
In northern China, droughts have become more frequent and severe in recent decades. However, the increased drought risk does not appear to be consistent with climate model projections, which generally expect wetter conditions as the monsoon rain belt is displaced northward by global warming. This may be due to local climate feedbacks that are not captured in the models, or it could simply be a result of decadal variability.
Floods are the most common natural disasters and occur when an overflow of water submerges land that is normally dry. They are typically caused by consistent rain or rapid snow melt in rivers, and storm surges associated with tropical cyclones or tsunamis in coastal areas.
River flooding occurs when the water level rises up over the bank or levee, inundating the surrounding land and other normally dry areas. This can be triggered by heavy rain, melting snow or a dam or levee breach.
In some regions, periodic floods can provide important benefits to farmers and their crops. They replenish groundwater, make soil more fertile and spread nutrients in some agricultural areas. They can also kill pests and weeds.
However, in many parts of the world, floods are very dangerous to people and livestock. They can cause loss of life and damage infrastructure, such as roads and power lines. They can also contaminate drinking water with human and animal sewage, increasing the risk of illness from diseases like typhoid, giardia, cryptosporidium and cholera.
Sea Level Elevations
Across the globe, the oceans are rising as a result of warmer global temperatures, which cause ocean water to expand. In addition, melting glaciers and polar ice caps add water to the surface.
Sea level rise threatens low-lying communities worldwide. It threatens the infrastructure of coastal cities and towns, disrupts the flow of vital natural resources such as freshwater and food, and exacerbates flooding, which increases risks of injury and death and contaminates homes and public buildings. It also impacts mental health by reducing access to secure income and safe physical environments, triggering eco-anxiety or solastalgia in vulnerable individuals.
Local mean sea level (MSL) is measured using tide gauges. It is calculated by weighting data from hundreds of tide gauges around the world and adjusting for seasonal differences. The results are then compared with satellite altimeter measurements to determine the total amount of water added to the surface. This information is then used to estimate how much the global ocean is changing.
