My understanding is that Climate Change affect the quantity of agricultural produce due to the reduction in the supply of rainfall. I am not sure of the effects of CIimate Change on the quality of agricultural produce.
Climate Change have a great impact on water resources. Then, it will affect quality of products.
Yes climate change affect quality of agricultural produce, i found in my study that water deficit affect quality parameters of stevia please read this paper: Productivity of new sweet plant in Morocco (Stevia rebaudiana Bertoni) under water stress
Climate change will induce drought stress on crops. The stresses could impact the availability of key soil nutrients needed for optimal growth and development . It will also affect the "hydraulic system" of plants. ie-even when nutrients are available, transport from soil to shoots is impeded by the drought stress or does not facilitate this upward movement of soils nutrients. Under such circumstances, not only quantity/yield is affected but quality is as well compromised.
In case of medicinal and aromatic plants I think it will improve the quality by stress inducement the alkoloides secretion will be more in plants thus increasing the concentration of phytochemicals.
Climate change affect on productivity of different crops, as quantity of yield and quality too.
Rainfall is not the single most climatic factor affecting crop growth and productivity. High temperature and/or low temperature, CO2 concentration in the atmosphere, ozone and etc. are either directly or indirectly affecting crop growth and productivity; and quality as well. For example soil moisture due to shortage of rainfall can affect quality of fruit crops, in such circumstances crops tend to reduce the size of the harvestable product, number of seeds, grain weight; seed size can be shirinked (soybean).
Climate change has both direct and indirect impact on all the abiotic factors which directs the quantity as well as quality of crop. Quantity is also driven when climate change is not concerned. But as climate change is the long term phenomenon, it changes the constituents driving quality of crop directly or indirectly. Furthermore, first impact of climate change is/will be on the available water to the plant, which leads all the required nutrients available to plant. So, when there will be any deterioration on the available water definitely it will have first impact on the mineral constituents of the crop grains/vegetables and so on.You may find following article more interesting: Data Impacts of climate changes on crop physiology and food quality
Climate change affects both quality and quantity of agricultural produce. The point to note is that climate change leads to drought in some places and flooding in others. This is why it affects both quality and quantity depending on the geographical area in question.
Climate Change is a broad term including global warming, reduction in rainfall etc. Climate change is affecting quantity as well as quality of agricultural products.
Climatic stress can affect to quality because the plant will not get the necessary nutrient and favorable condition to express its potential.
that's a very general question but climate change has so many different aspects and is potentially so profound that yes it would affect both quality and quantity . there's far too many factors to consider but location geography and variations in microclimates..
it is difficult to say and depends on the range of the temperature change and the different parameters included: e.g. differeces day and night, rainfall, periods of the year, winter and summer lenght, ...
For some species only the yield will be specially affected (e.g. grasses), in other cases also the quality will be inflenced (e.g. fruits) and mostly quatity and quality can be changed.
The effect of limited or intermittent limited moisture affects the quality of the fruits, along with the fructification, that is, the time of flowering in the case of plants, is affected in the pollination, and the product leaves rickets and bad quality. There are genetic advances in annual crops to counteract the negative effect of quantity and quality. regards
Hello Anthony,
Your question is too open because climate change is a very broad terminology. For experts here to be of much help, you need to specify which aspect (s) of climate change on crop yield quality and quantity you are investigating.
Otherwise, best of luck!
Regarding CO2 levels, the increased amount in the atmosphere leads to generally quicker crop-growth, but also to a change in composition; relatively more sugars/starches in comparison to minerals/vitamins, because increased CO2 means easier sugar production for plants.
Poignantly, this also relates to pollen quality and bee nutrition. One suspected cause of the decline in bees is the strongly decreased ratio of proteins in bee food due to CO2-fertilisation. E.g. goldenrod pollen has 30% decreased protein now compared to 170 years ago: https://e360.yale.edu/features/bee_collapse_co2_climate_change_agriculture
Thank you all for the valuable submissions made.
I am sincerely grateful

- There are different aspect of climate change impact on Agriculture. . we may express like social aspect , economic aspect, and The main factors which affects most are the climatic factors like annual rainfall,difference in temperature and others causes decline in the productivity of crop but it also affects the quality of produce i.e in term of size of grain , color of grain , texture of grain etc climatic vulnerability assumed to be positively related to the indicators such as variances in annual rainfall as well as minimum and maximum temperature variances, indicated that any increase in the variability of these climatic indicators would induce vulnerability of food production in a major way.
- Yield is more uncertain with unfamiliar technology. However, it could be seen that higher yields of crops led to higher incomes of the farmers and thereby increasing their risk bearing ability to various shocks.
In highly vulnerable region due to change in climate the resilience of farming and food systems to climate change impacts will be affected most, .due to change in cropping practices, time of planting etc causes declined in production , not in physical terms but all the quality attributes of the produce affected .
Dear colleagues, in fact the quality of production will always be a problem with few rains and many, in the case of the common bean, which work, in the area of improvement I have observed stressed plants in both cases with irregular grains, so There will always be a selection of manual grain, discarding the poor quality of the grain. Therefore, that diminishes production. Thanks for the space.
Climate change causes adverse impacts on both ecosystems and human societies as it increases the incidence of floods, droughts and other
climate-related disasters that have the potential to affect farmlands, livestock and animal husbandry,which are essential for agricultural purposes. Thus three factors identified to have the most direct effects
on food production: soil, water and crops which has direct impact on quantity and quality of produce i.e related with food security.
Anthony Baidoo, here you can find how climate change affects the quality of produced food:
