The question is far to complex to answer generally. An answer needs to specify the location, the kind of crops, and a lot more. CC is not always a challenge, at times increasing CO2 and temperatures can even improve conditions for crop growth. There has been plenty of research done on this. Also plenty of publications that provide overviews and syntheses (e.g. the IPCC reports, which direct also to relevant research).

Nice issue to be raised in such comprehensive form ....

Climate change is often seen as something that occurs in the atmosphere. After all, when plants photosynthesise, they draw carbon out of the atmosphere. But atmospheric carbon also affects the soil, because carbon that is not used for above-ground plant growth is distributed through the roots of a plant, which deposit carbon in the soil. If undisturbed, this carbon can become stable, and remain locked away for thousands of years. Healthy soils can thus mitigate climate change. When it comes to carbon storage, not all soils are equal. The most carbon-rich soils are peatlands, mostly found in northern Europe, the UK and Ireland. Grassland soils also store a lot of carbon per hectare. In contrast, the soil in warm and dry areas in southern Europe contains less carbon.

The increasing concentration of carbon dioxide in our atmosphere may cause the microbes in the soil to work faster to break down organic matter, potentially releasing even more carbon dioxide. The release of greenhouse gases from the soil is expected to be particularly substantial in the far north of Europe and Russia, where melting permafrost may release large quantities of methane, a greenhouse gas much more potent than carbon dioxide.

Global change is altering species distributions and thus interactions among organisms. Organisms live in concert with thousands of other species, some beneficial, some pathogenic, some which have little to no effect in complex communities. Since natural communities are composed of organisms with very different life history traits and dispersal ability it is unlikely they will all respond to climatic change in a similar way. Disjuncts in plant-pollinator and plant-herbivore interactions under global change have been relatively well described, but plant-soil microorganism and soil microbe-microbe relationships have received less attention. Since soil microorganisms regulate nutrient transformations, provide plants with nutrients, allow co-existence among neighbors, and control plant populations, changes in soil microorganism-plant interactions could have significant ramifications for plant community composition and ecosystem function. In this paper we explore how climatic change affects soil microbes and soil microbe-plant interactions directly and indirectly, discuss what we see as emerging and exciting questions and areas for future research, and discuss what ramifications changes in these interactions may have on the composition and function of ecosystems.Source :DOI: 10.1890/ES15-00217.1. There are certain frequently asked questions as below , need to be clearly differentiated before discussion peaks up : 

What is the difference between weather and climate?

What is climate change?

What is the difference between climate change and climate variability?

The greenhouse effect and climate change

 Various conservation practices and climate change

Climate change impacts on agricultural production

Some preliminary issues to set the discussion in right direction....

The question is far to complex to answer generally. An answer needs to specify the location, the kind of crops, and a lot more.

I also agree to the previous comments, and it is a very complex problem to sort it out and we need a holistic approach to solve these issues raised and also it will vary from site to site. Hence site specific management options needs to be thought of and it should involve multidisciplinary team to address the specific issues because all are inter related . Any way started an important discussion point and looking forward for more participation

Currently I am also working on two projects in relation to this topic - Carbon sequestration of different land uses and linking to climatic parameters

Crop modeling and Soil Nutrient Budgeting 

Besides, I am also suggesting that we can even think of framing a proposal in this line with the interested researchers from different places and work on this line

very useful sharing 

Grt Info & so nice to have shared with all on RG.

Thanks Dr Anoop Kr Sriv.

Already several reports suggested that insect population will increase under projected climate change scenario. As far as insects are concerned, climate change may impact crop-pest synchrony, interspecific interactions, geographical distribution, population growth rates, period of the activity, number of generations, overwintering success and invasion by migrant pests. Due to climate change the frequency or intensity of pest outbreaks has been increased in many parts of India. Increased temperatures can potentially affect insect survival, development, geographic range and population size. In the rice ecosystem in the last one decade lot of insect pest outbreaks occurred, like brown planthopper (Tamil Nadu, Odisha, Punjab, Haryana), Stem borer (Jharkand, Chattisgarh, Andhra Pradesh, pudhucherry), case worm (Jharkand, Odisha, West bengal, Assam), swarming caterpillar (Odisha, Assam, Haryana). Other than these pests, in certain pockets of rice cultivation also experienced the damage of rice hispa, Gundhi bug and blue beetle.

 Adaptation/Mitigation Strategy

· Increasing agricultural diversity through crop variety and germplasm adapted to shifting agro-ecologies

· Early transplanting may escaped from insect attack

· Soil management practices that reduce fertiliser use and increase crop diversification

· Promotion of legumes in crop rotations

· Rescheduling of Crop Calendars

· Screening of Pesticides with Novel Mode of Actions

· GIS Based Risk Mapping of Crop Pest

·  Promotion of low energy production systems and avoiding burning of crop residues

Good Collection..........Written in a well manner

The climate exchange is expected to seriously affect agriculture. In particular, water requirements of crops will be difficult to meet which will consequently reduce yields of crops. Soil salinity and sodicity is specifically going to be disturbed. Low rainfall and high temperature are pro salt accumulation in arid zones. It means that salinity and sodicity will increase and become more difficult to manage.  

This is a very important issue. Impact is visible. For this reason, the low carbon economy should be part of sustainable development of rural development. With regard to rural areas, the concept of sustainable development is particularly important because of the need for taking into account the priority role of the natural environment in the implementation of the production function and the strategic objectives of the development of these areas. This approach brings together the laws of nature and the economy by following economic activities in the chosen direction of development,

adapted to the existing natural conditions, as well as the needs and will of local communities and environmental standards. The realization of the vision of a low carbon economy in rural areas should, therefore, be an essential element of their sustainable development. 

I conduct such research at local level in Poland.

You are right, we need this to stay low because in cities the GHG is really high. That is why the products should follow the carbon footprint.

Currently my doctoral thesis proposal is the carbon footprint en banano crop.

Air enrichment of greenhouse gas such as CO2 increases air temperature. This temperature increase influences globally climate components such rainfall which becomes more and more random. From a season to another, we can not predict the quantity of rain water we will have. This can become abundant in a short period, inducing flood, or rare, inducing drought. Some crops and animals cannot then find their best conditions to grow.  This deals to yield and food production decrease. And the mineralisation of the organic matter in the soil will be rapid, inducing soil chemical, biological and physical degradation.

Biochar is effective in enhancing the soil fertility and plant growth by proliferating beneficial soil microorganisms, However, it is still unclear to understand the ecological

interactions between biochar, soil, plant roots and microorganisms. Lfe-cycle assessment can help identify strategies to balance the multifarious biochar

benefits over these few trade-offs. Such analysis can motivate biorefineries to practise carbon sequestration scheme, i.e. utilizing the main product of interest. Please find enclosed a review article in this line

GHGs in the production of certain crops have not been studied due to the small importance given to this phenomenon, but what is recommended is to perform good agricultural practices to minimize their effect.

In short, the carbon footprint is around 9% in the processing of a banana box

Climate change will definitely change the soil microflora including number and types of fungi and bacteria the crop microbe interaction will be affected more which will impact crop production

Actually our interest is the climatic change and its impact on agriculture, let us have the virtual means to do an online seminar to discuss important aspects of our peoples to make recommendations to prevent this problem for the future that we see.

I live in the province of the Ecuadorian gold I can shed on the use of well water in agriculture and its impact on the salinity of soils

We have tried to evaluate the impact of increased temperature together with greater levels of CO2 for dry season irrigated rice in Bangladesh through DSSAT. It reveals that somewhat compensation is likely with increased CO2 levels.

Soil Ecology will be most affected , with the result, there is hardly any soil property remaining unaffected with climate change related issue(s)..

The SAVA bassin commission, under the UN, has done some amazing  computer modeling analysis of existing factors and, more importantly projected impacts. This is particularly useful where crops are grown for export , but increase damage.  The knowledge allows regions to make informed decisions, vary crops and impacts, based on benefits.

Dear Helen R Finn

An interesting study. Where can I find the results of this modeling?

Yours sincerely

  Hi Pawel

It is the nexus river basin  approach. You will find it and several others at the link below. In transboundary rivers, the idea is that it can prevent wars over resources. The UNECE has used it in various regions around the world.

Climate change may directly or indirectly affects sustainability of agriculture. It affects the suitability of factors governing plant growth. It influences the amount and distribution of rainfall, temperature, soil quality, and other crop related traits. Increased CO2 in the atmosphere might raise temperature beyond the cardinal temperature required for crops. Rainfall may become erratic with devastating flood during occurrence. Every climatic parameters become different from the normal situation. These climatic changes, specifically rainfall and temperature, are the dominant factors shaping the quality of soil. Thus, climate change affects soil quality by influencing rainfall and temperature, those factors governing soil physico-chemical and biological properties. Meanwhile, the sustainability of agriculture depends on the quality of soil.

How many of you feel, agriculture has started facing more complex challenges due to climate change , with the result, agriculture has  become more vulnerable to uncertainty...

Really, the challenges of climate change on agriculture is more obvious in developing countries. I observed total crop loss and livestock deaths in 2016 due to drought uncommon in the past decades in Ethiopia. This is because of climate change which led to more than 10 million people to look for food aid. Meaning, "no rain - no agriculture - no food".

I see three related problems: adapt agriculture to climate change, ensure food security and reduce greenhouse gases emissions from this sector.

During the recent decade, with the growing recognition of the possibility of climate change and clear evidence of observed changes in climate during 20th century, an increasing emphasis on food security and its regional impacts has come to forefront of the scientific community. In recent times, the crop simulation models have been used extensively to study the impact of climate change on agricultural production and food security. 

Follow the paper which is a comprehensive review on Impact of Climate Change on Indian Agriculture by Prof. Mall

The discussion participants highlighted the problem rightly and significantly. 

Jawanta Kumar Biswas articulated the climate change problems very well. it depends on the dimension of your focus.

An often overlooked effect of rising CO2 is the dilution of nutrients and decrease in plant quality. See article in link!

Crop varieation with in-depth analysis through experimental design is necessary beacuse it varies as per ecological, climate, metrological and  etohological conditions.

Dr. Shrivastava already given detailed inputs. Certainly climate change is going to change agro-ecosystem . some of the changes started with rise in soil temperature, water issues, erratic pattern of rainfall and change in seasons on crops. I think except protected cultivation all open field cultivation that too rainfed agriculture is going to most affected in tropics. Agroforestry adoption can be used a mitigation strategy to some extent.

Depends in location , as the Climate change effect in desert areas (increase in temperature and dusty events) will cause gradual change in th agriculture type, density and diversit. Also , some new fungi and microorganism will develo.

Its a real challenge to domesticate agriculture according to changing climate and sustain the galloping pace of agriculture with such vagaries....

The impact is certain. But its degree would depend upon the kind of harvest, climates and evology of different geographical regions.

Under the present climate change circumstances the conventional model of farming is going to become negatively affected more and more as the homogeneity of germplasm and agronomic practices on a large scale put agricultural outputs at grave risks of continuous failure. Salvatore Ceccarelli's concept of evolutionary breeding has had already success in some agriculturally marginal parts of the world. The efforts of Wes Jackson's Land Institute to perennialize agronomic crops has also potential to make agriculture more adaptive and resilient to the whims of unpredictable, changing weather patterns. Agrobiodiversity of crop/livestock populations, agricultural communities and agroecosystems is indicating a step further the potential to cope with a changing climate and (possibly) avoid a collapse.

Dear all, I’ve found interesting new review auf Martha Vaughan concerning effects of climate change on changes in phytochmicals: (doi.org/10.1007/s11101-017-9508-2): Climate change will influence maize phytochemicals associated with resilient productivity. Under drought defense phytochemicals such as benzoxazinoids will stimulated in above plant parts, but belowground terpenoids will deployed. This may be important: Changes in allocation or distribution of defense or signaling compounds of plants will have some impacts on plant pests and diseases, the damage caused by them and their economical importance.

Hello everyone. First is important advice the positive effects for CAM plants. Cacti, Grapes and pineapple crops would obtain benefits in some regions with the change of rainfall. Certainly pest amount is a peril for all, not only for the plants and therefore will be urgent the implementation of integrated control of the pests with the cooperation between agriculture, health and wildlife authorities. I think however, that the C3 plants could be the prefered crops to alleviate the global hunger. It was explained in the works of Johnson and other scientists.The future scenario requires new strategies in the obtention of food as the extraction of proteins from leaves or the harvest of forage crops irrigated with seawater.

But, is it possible to reverse the evolutionary chain of C4 to C3 plants? Environment has had its iwn evolutionary scenario, so did the C3 to C4 plants. But, we may give a trial.

Thanks
