Climate change has serious negative impacts on agriculture crops production in Pakistan. This sector contributes 21 % of Pakistan’s economy. About 80% agricultural yield is produced by cultivation of land through the world largest integrated irrigation system. This report reveals that climatic condition in Pakistan causes of extreme temperature, less rainfall, variation in precipitation, rapidly glacier melting and increase in evaporation, releases of GHG emission, and crop water requirements. In addition, both urban and rural areas are also contributing to climate change.
temperature will be increased up to 3 Celsius by 2040 and 5-6 Celsius at the end of this century (Siddiqui et al., 2012). Due to a higher temperature, Asia region can lose over 50 percent of its wheat production (Siddiqui et al., 2012). Furthermore, the agricultural sector of Pakistan is more vulnerable from climate change due to geographical area (Siddiqui et al., 2012). Generally, Pakistani economy depends on agriculture sector but unfortunately, this sector is facing very serious problems such as shortage of irrigation water and less rainfall due to unpredicted climate change (MENHAS, Umer, & Shabbir, 2016). Pakistan is ranked 12th on the list of those countries which are most vulnerable to the impacts of climate change (Piracha, & Majeed, 2011).
Mankind has abused nature for far too long and would pay a heavy price unless urgent remedial measures are undertaken. The aim of this document is to take a look at the measures already taken by mankind to reduce the effects of climate change and also suggest additional measure which could be taken by countries around the world after analyzing the current scenario. Author: Commitee on Ecological Impacts of Climate Change Document name: Ecological Impacts of Climate Change Pg 13 Chapters reviewed What exactly is climate change? How does it occur? Climate change can be defined as a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.c Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions.
Obviously it doesn’t seem well. There are some changes as climate changes, holes in the ozone layers, decreasing natural resources. Global warming is essential issue for all living creatures. Carbon dioxide was overloaded and this caused to global warming. Global warming has been changing climate.
The issue of climate change has become a common challenge for both developed and developing countries. Climate change has a visible challenge on the lives and livelihood strategy of developing nations. It has been is one of humanity’s greatest challenges and it is believed that within the next fifty (50) years, global warming will increase to the detriment of the world’s population. It is a serious threat has the potential to cripple sustainable development by adversely impacting the environment, human health, ecosystem and diversity, food production and security, and economic activity (Abafura, 2011) Climate change refers to the average temperatures and precipitation rates over an extended period of time. It includes shifts in the frequency
Also have implications for humans. Pollution in the air can cause problems for environment and the planet we live on, our big industries that transfer a lot of carbon dioxide in the air. The Ozone and also the atmosphere get affected. Changes in climate impact on
Climate Change – How important is awareness of the causes of climate change? I am interested in this topic because it is one of the most important problems we face today. Climate change affects not only to humans but also to all living things. Global Health becomes worse and worse because of the change, and it is now significantly be seen. Global warming, the ozone layers being damaged, deforesting, rivers drying up, unbalancing ecosystem and different kinds of pollution lead to certain climate change.
Understanding climate change and its impacts on agricultural sectors is crucial, since climate is the primary determinant of agricultural productivity. Studies have shown that climate changes and extreme climatic events pose great threats to food and water security, public health, natural resources and biodiversity (McCarthy et al 2001, IPCC 2007). Given the fundamental role of agriculture in Africa, concern has been expressed by scientists about the potential impacts of climate change/variability on agricultural productivity. Studies have revealed that African countries are likely to be more severely affected because of their lack of adaptive capacity to climate change or variability (Kandji & Verchot 2006; Boko et al. 2007; Ole et al 2009).
Climate change is now acclaimed as one of the most arduous and complicated problem confronting the globe. The risk factors are very high and the impacts would raise considerably the developmental impediments of safeguarding livelihood security and poverty eradication in most Sub-Saharan African (SSA) nations in general (IPCC, 2014) and Northern Ghana in particular. Climate and ecological change has intensified potentially unexpected and permanent disruptions of life and livelihood-sustaining natural systems, leading to socio-cultural, economic and environmental disruptions (UNSCEB, 2008). Current climate change projections by climate experts indicate progressively severe negative impacts on many countries across the world (IPCC, 2014). However,
Agriculture is an important sector of a country's economy starting from farming, livestock and marine products as well as supporters of the economy. Here, the sector of agriculture is very dependent on a climate where extreme weather can make rainfall patterns do not significantly, so the risk that will get by the farmers is the quality of the crop that is not satisfactory due to increased pests and plant diseases even some of those who experienced late in the harvest. In general, climate change will have an impact on shrinkage and degradation of land resources, water, and infrastructure, especially irrigation, which led to the threat of drought or flood. Food security is threatened as a result of temperature instability, also with the water temperature in the sea is getting warmer causing native species in these habitats migrate to their survival and are likely to damage the ecosystem. 2.
