2) The majority of farmers perceived negative effects of climate change on soil fertility, crops grown, cropping patterns, use of chemical fertilizers, pest infestation, and grain yield. Nearly all farmers observed effects on timing of operations and increased pesticide use.
3) Regarding livestock, the vast majority (over 90%) of farmers perceived negative effects on the type and number of livestock reared as well as reduced milk yields from climate
This document discusses the effects of climate change on agriculture. It begins with an introduction on global warming and how increased greenhouse gases are causing temperatures to rise. It then looks at how climate change has historically affected agriculture, both positively and negatively. The document predicts that rising temperatures will reduce crop yields through heat stress and changing growing seasons. However, it also notes that some regions may experience increased yields. It concludes by considering policy options to help agriculture adapt to climate change, such as developing hardier crops and more sustainable water use.
Climate change and Agriculture: Impact Aadaptation and MitigationPragyaNaithani
Climate change refers to a statistically significant variation in either the mean state of the climate or in its Variability, persisting for an extended period (typically decades or longer). For the past some decades, the gaseous composition of earth’s atmosphere is undergoing a significant change, largely through increased emissions from energy, industry and agriculture sectors; widespread deforestation as well as fast changes in land use and land management practices. These anthropogenic activities are resulting in an increased emission of radiatively active gases, viz. carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), popularly known as the ‘greenhouse gases’ (GHGs)
These GHGs trap the outgoing infrared radiations from the earth’s surface and thus raise the temperature of the atmosphere. The global mean annual temperature at the end of the 20th century, as a result of GHG accumulation in the atmosphere, has increased by 0.4–0.7 ºC above that recorded at the end of the 19th century. The past 50 years have shown an increasing trend in temperature @ 0.13 °C/decade, while the rise in temperature during the past one and half decades has been much higher. The Inter-Governmental Panel on Climate Change has projected the temperature increase to be between 1.1 °C and 6.4 °C by the end of the 21st Century (IPCC, 2007). The global warming is expected to lead to other regional and global changes in the climate-related parameters such as rainfall, soil moisture, and sea level. Snow cover is also reported to be gradually decreasing.
Therefore, concerted efforts are required for mitigation and adaptation to reduce the vulnerability of agriculture to the adverse impacts of climate change and making it more resilient.
The adaptive capacity of poor farmers is limited because of subsistence agriculture and low level of formal education. Therefore, simple, economically viable and culturally acceptable adaptation strategies have to be developed and implemented. Furthermore, the transfer of knowledge as well as access to social, economic, institutional, and technical resources need to be provided and integrated within the existing resources of farmers.
Impact of climatic change on agricultureShashi Singh
Climate change is caused by both natural and human factors such as greenhouse gas emissions and fossil fuel burning. It is leading to rises in global temperature, changes in precipitation patterns, more extreme weather events. These changes are negatively impacting agriculture through reduced crop yields, shifts in suitable farming areas, and increased pest and disease pressures. While some factors like carbon dioxide fertilization may slightly increase yields, the overall impacts of climate change on global agriculture are expected to be severely damaging to food production and security.
Climate change parameters such as increasing CO2 concentrations, rising temperatures, and shifting rainfall patterns can impact crop duration and productivity. Higher temperatures above optimum levels can reduce wheat, rice, and maize yields by 8-25% with each 1°C rise. Elevated CO2 can increase photosynthesis and yield for C3 crops like soybean but have less effect on C4 crops. Higher temperatures may shorten crop durations for wheat, rice, and maize according to studies from India and other countries. Rainfall changes can also significantly impact yields, as shown by a 70-90% increase in maize yields during wet years compared to dry years in one analysis.

Climate Change and Agriculture by Muhammad Qasim & Aroj BashirMuhammad Qasim
Climate change is negatively impacting agriculture in Pakistan in 3 main ways:
1) Changing temperatures and rainfall patterns are decreasing crop yields, especially for wheat which is estimated to decline by 6-9%.
2) Recent floods have destroyed over 2.6 million acres of agricultural land.
3) Glacial melt from the Himalayas due to rising temperatures threatens water availability, which Pakistan's agriculture sector heavily depends on for irrigation.
Climate change poses serious threats to Indian agriculture that could undermine food security. Studies project cereal production may decrease 10-40% by 2100 due to increased temperatures, with wheat facing greater losses. Every 1°C rise in temperature could reduce wheat production by 4-5 million tons. Adaptation strategies like new crop varieties, water management, and insurance can help minimize impacts but require significant research and policy support. Immediate action is needed on low-cost adaptation options while determining costs and policies for long-term mitigation through practices like agroforestry and soil carbon sequestration. Failure to act risks substantial economic and social damages from climate impacts on India's agricultural sector and food system.

Impact of agriculture on climate change Kinza Irshad
Agriculture contributes significantly to climate change through greenhouse gas emissions. Agriculture is responsible for about half of global methane emissions from livestock digestion and 60% of anthropogenic nitrous oxide emissions. Modern industrial agricultural practices such as the use of fertilizers and pesticides, deforestation, and burning of agricultural residues release greenhouse gases and damage soil and biodiversity. Mitigation efforts include carbon sequestration, reducing emissions through drip irrigation and crop covers, and adopting sustainable practices like crop rotation and diversification.
Climate change is negatively impacting agriculture in India. Rising temperatures are shortening crop growing periods and reducing yields of wheat, rice, maize, and other crops. Higher temperatures combined with increased CO2 levels can decrease crop nutrition. Climate change is also worsening soil health, affecting livestock and fish production, and increasing pest and disease pressures. Projections indicate continued temperature rises and more extreme weather, posing severe threats to Indian agriculture and food security over the coming decades.
Economic perspectives on the impact of climate change on agricultureharrison manyumwa
The world's climate is changing, and the growing evidence is that the major drivers are anthropogenic, i.e. caused by humans. While humans are contributing to the changing climates the impacts of climate change on other humans range from minor to severe depending on the region one is located. As such, climate change has been viewed as a problem with a negative exernality. The diverse distributionl impacts have resulted in "winners" and "losers". But what is the way forward. I argue that "winners" should support and help the "losers" regain a normal life, by helping them to be resilient. Enjoy.

Climate change will significantly impact agriculture and food security in India. Rising temperatures, changing rainfall patterns, and more frequent extreme weather events will affect crop yields, livestock, and fisheries. Higher temperatures can reduce yields of major crops like rice, wheat and soybean. Pests, diseases and weeds will also spread to new areas, posing additional threats. Livestock will face heat stress and lower milk production. Fisheries may see increased catches but ocean acidification could damage shells of shellfish. To ensure food security, India needs strategies like switching crops, establishing food reserves, and developing climate-resilient varieties.
Climate change and its effect on field cropsNagarjun009
Climate change is causing rising global temperatures due to increased greenhouse gases. This is impacting field crops through higher temperatures and altered rainfall patterns. Studies project declines in yields of rice by 0.75 tons/hectare, and wheat, cotton, sorghum and groundnuts by 14-60% under climate change. Adaptation strategies like improved varieties and water management can reduce these impacts. Mitigation involves practices to reduce greenhouse emissions from agriculture through methods like efficient fertilizer use, rice cultivation techniques, and afforestation. Further research is needed to develop technologies that minimize agricultural greenhouse gas emissions.

This document outlines the challenges, program design, progress, and cross-cutting issues of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). CCAFS addresses 3 main challenges: food security, adaptation to climate change, and reducing agriculture's environmental footprint. Its objectives include identifying adaptation and mitigation practices, supporting inclusion of climate issues in agriculture policies, and place-based research in key regions. Progress includes work on adapted farming systems, climate-resilient crops, integrating adaptation into policies, and identifying low-carbon agriculture pathways. CCAFS also focuses on cross-cutting issues like gender, communications, measuring impact, and knowledge sharing.
Global climate change is a change in the long-term weather patterns that characterize the regions of the world. The term "weather" refers to the short-term (daily) changes in temperature, wind, and/or precipitation of a region. In the long
run, the climatic change could affect agriculture in several ways such as quantity and quality of crops in terms of productivity, growth rates, photosynthesis and transpiration rates, moisture availability etc. Climate change is likely to directly impact food production across the globe. Increase in the mean seasonal
temperature can reduce the duration of many crops and hence reduce the yield. In areas where temperatures are already close to the physiological maxima for crops, warming will impact yields more immediately (IPCC, 2007). Drivers of climate
change through alterations in atmospheric composition can also influence food production directly by its impacts on plant physiology. The consequences of agriculture’s contribution to climate change, and of climate change’s negative impact on agriculture, are severe which is projected to have a great impact on food production and may threaten the food security and hence, require special agricultural measures to combat with.
This document discusses the impacts of climate change and global warming on agriculture. It notes that agriculture depends on climate conditions like temperature, moisture levels, and more. Changes in droughts and floods from climate change could pose challenges for farmers and disrupt ecosystems by shifting fish and shellfish habitats. Climate change could make it harder to grow crops and raise animals in the same ways and places. It also discusses effects like reduced crop nutrition and increased pests from climate change. Global warming is defined and its causes like fossil fuel use and farming practices are outlined. The effects of global warming may include increased crop pests, greater crop losses from droughts and floods, and decreased cereal production.

The Earth's climate has varied vastly in the history. Climate change is the change that can be attributed directly or laterally to mortal exertion that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over similar time ages. The climate sensitivity of agriculture is uncertain, as there is regional variation in rainfall, temperature, crops and cropping systems, soils and management practices. Increase in water and air pollution causing migration of birds and animals as well as decrease in drinking water availability. So, Changes occurred in flowering and fruiting time of crops causing scarcity of fodder in area was affected most impact on Climate Change. The crop losses may increase if the predicted climate change increases the climate variability. Climate change will have its impact on the particulars like Vulnerability to Extreme Events, Impacts on Coastal Areas, Impacts on Biodiversity, Impacts on Pest, Impact of Climate Change on Disease and Crop Loss. The intermittent famines hang seriously the livelihood of billions of people who depend on land for utmost of their requirements. Among the greenhouse effects, CO2 is the predominant gas leading to global warming as it traps long surge radiation and emits it back to the earth surface. The global warming is nothing but heating of surface atmosphere due to emission of greenhouse gases, thereby increasing global atmospheric temperature over a long period of time. There is strong evidence of increase in average global air and ocean temperatures, widespread melting of snow and ice, and rising of average global sea levels. The policies and the mission should ensure the Sustainability of the agricultural development. The need of the hour is strengthening the agricultural policies and programme to address the issues related to impact of climate change.

IMPACT OF GLOBAL WARMING ON AQUATIC FLORA AND FAUNAMahendra Pal
A rise in temperature as small as 1° C could have important and rapid effects on the geographical distributions and mortality of some organisms. The more mobile species should be able to adjust their ranges over time, but less mobile and sedentary species may not.There are many factors that can cause a warming of our climate; for example, more energy from the sun, large natural events such as El Nino or an increased greenhouse effect. Rising temperatures can directly affect the metabolism, life cycle, and behaviour of marine species. For many species, temperature serves as a cue for reproduction. Clearly, changes in sea temperature could affect their successful breeding. The number of male and female offspring is determined by temperature for marine turtles, as well as some fish and copepods (tiny shrimp-like animals on which many other marine animals feed). Changing climate could therefore skew sex ratios and threaten population survival.
Influence of climatic changes in east coast of copyabirami manni
Climate change is negatively impacting agriculture and food security in the Cauvery delta region of Tamil Nadu, India. Paddy is the main crop grown, but rising temperatures and irregular rainfall have reduced productivity in recent times. This has seriously affected farmers economically. Additionally, urban areas are expanding and occupying agricultural lands. With improper rainfall, food shortages may occur in the future as the population grows. To improve this situation, climate-smart agricultural practices should be adopted, along with conserving agricultural lands, supporting farmers, and raising awareness of new technologies.
Climate change will negatively impact global food production and supply in several ways:
1. Rising temperatures, droughts, and extreme weather from climate change will reduce crop yields for many plants worldwide, especially in dry and tropical regions. This will decrease global food availability.
2. Climate change will also harm livestock through heat stress, drought reducing pastures and feed, and increasing diseases. It may also decrease the nutritional quality of livestock feed.
3. Fisheries will be negatively impacted as some fish species shift ranges, diseases spread, and ocean acidification harms shellfish. This threatens food supplies and livelihoods in fishing communities.
"Unveiling the Global Warming Crisis: Understanding its Causes, Impacts, and ...sharmasimran2309
Global warming is the gradual rise in Earth's average temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide and methane. These gases trap heat in the atmosphere, leading to a range of environmental impacts. Melting ice caps, rising sea levels, altered weather patterns, and shifts in ecosystems are among the consequences. Human-induced global warming accelerates climate change, posing threats to biodiversity, agriculture, and human communities worldwide. Urgent measures such as reducing emissions, adopting renewable energy, and implementing sustainable practices are crucial to mitigate its effects and preserve a stable climate for future generations.
Global warming refers to the long-term rise in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide, methane, and nitrous oxide. These gases trap heat in the atmosphere, leading to the gradual warming of the planet. As a result, glaciers and polar ice caps are melting, causing sea levels to rise and threatening coastal communities. Extreme weather events such as hurricanes, droughts, and heatwaves are becoming more frequent and intense. The warming also disrupts ecosystems, leading to biodiversity loss and endangering numerous species. Urgent action is required to mitigate global warming and its devastating impacts on the environment, economies, and human well-being.
Climate change is accelerating due to human activities and its impacts are becoming more severe. It is causing ocean acidification and rising sea levels as oceans warm and expand. Glaciers are melting, contributing to sea level rise. Heat waves and droughts are more common, while precipitation patterns are changing and becoming more extreme. This is reducing agricultural production and increasing food insecurity. Other impacts include more frequent extreme weather, spread of diseases, disruption of ecosystems, and increased health problems. Urgent action is needed to reduce greenhouse gases and mitigate the effects of climate change.
Climate change is accelerating due to human activities and its impacts are becoming more severe. As the global temperature rises, oceans are warming and acidifying while glaciers and ice sheets are melting, causing sea levels to rise. Heat waves are occurring more frequently and intensely, while droughts are lengthening and precipitation patterns are changing, reducing food security. Climate change is also exacerbating natural disasters, spreading diseases, and disrupting ecosystems. If greenhouse gas emissions continue unchecked, climate models predict increasingly elevated temperatures and sea levels that could threaten global livability. Urgent action is needed to mitigate climate change through emissions reductions and other measures.
Role of climate in crop productivity in salt affected soils-Bhaskar.pptxBhaskar Narjary
This document discusses the role of climate in crop productivity in salt-affected soils. It provides background on weather and climate, noting that climate is defined based on long-term weather averages. It then discusses various impacts of weather like rainfall, temperature, and extreme events on agriculture. It explains temperature impacts and temperature stresses on crops. It also discusses the significance of moisture, carbon dioxide, and climate change and variability on soil salinity and sodicity. Statistical analysis of long-term rainfall and temperature data for Karnal, Haryana is also presented.
Climate change is already transforming life on Earth through shifting seasons, rising temperatures, and sea level rise. The document lists several of the most dangerous consequences of climate change, including threats to agriculture and food supply from erratic weather patterns and drought reducing crop yields. Ecosystems like the Arctic and mountains are particularly vulnerable to climate change which can transform species' habitats and threaten their survival. Warming and acidifying oceans will disrupt coastal and marine ecosystems already stressed by pollution and weather disturbances. Rising seas will also displace people living in low-lying areas and cities through more frequent flooding.
Agriculture, Climate Change and Carbon SequestrationGardening
The document discusses how climate change influences agriculture and how agriculture influences climate change. It states that the Earth's average temperature has increased 1.3 degrees Fahrenheit over the past century and is projected to increase by 3.2 to 7.2 degrees this century. These increases could lengthen growing seasons but also increase drought risks. The document then outlines how agricultural practices like fertilizer use and livestock emissions contribute to greenhouse gas emissions, but that carbon can also be sequestered in soils through certain farming techniques.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
2. INTRODUCTION
Research was done by group members to find
out how climate change affects agriculture in
Jamaica and the following topics were
examined.
What is climate change?
What is agriculture?
How climate change affects agriculture in
Jamaica?
Recommendations
3. WHAT IS CLIMATE CHANGE?
Climate change is a long-term shift in weather
conditions identified by changes in
temperature, precipitation, winds, and other
indicators.
4. WHAT IS AGRICULTURE?
Agriculture , also called farming or husbandry,
is the cultivation of animals, plants, fungi and
other life for food, fibre, biofuel,medicinal
and other product used to sustain and
enhance human life.
6. Our climate is changing because as
human beings we have increased the
amount of certain gases, called
greenhouse gases, in our
atmosphere.
We burn oil, coal and gas to produce
energy for homes, factories,
businesses and for our
transportation needs.
7. The excess greenhouse gases in our
atmosphere are trapping too much
heat around the earth, making the
earth warmer and it is this increase
in temperature over time which
results in climate change.
8. Cause more extreme events and stronger
hurricanes
Passage of more extreme weather events
such as storms and hurricanes damage
agricultural assets including livestock,
crops and infrastructure. The impact of
storms is especially severe for standing
export crops like bananas, coffee and
sugar cane.
9.
10. Increase drought conditions
Agriculture relies heavily on local water
supply which in turn relies heavily on
rainfall. Longer periods of drought will
incur higher water and production costs
for food production.
11.
12. Increase drought conditions cont’d
Drought will also affect the quantity
and variety of agricultural produce
available for consumption and this
will increase the costs of food.
13. Increase drought conditions cont’d
Longer periods of drought can lead to
large scale losses of cattle and lower
reproduction rates among livestock.
The risk of degradation and reduced
productivity of the soil will increase
due to droughts.
16. Increase temperatures con’d
Citrus and root crops are sensitive to
changes in temperature and
precipitation (moisture). This results
in Jamaica’s domestic crops under
stress and food security is
threatened.
17. Results in a rise in sea level
Rising sea levels lead to increased
incidence of salt water intrusion in
coastal agricultural areas and
salinization of water supply.
19. Cultivate various crop varieties that are able
to withstand increasing temperature, the
growth of pests and drought conditions.
Improving agriculture infrastructure, so
that it can be climate sensitive. E.g. develop
water saving irrigation systems; water
management systems; construct on-farm
water storage (ponds, tanks etc) island
wide.
20.
21. Modify crop calendar for short term crops:
Crops which take a shorter time to recover
from severe weather events such as storms
and hurricanes.
Adopting improved technologies for soil
conservation.
Establish system of food storage to ensure
food security in times when agricultural
output is affected by extreme weather
events.
