Agriculture is both affected by climate change but also contributes to it. As a sector, agriculture must therefore both adapt to changes and offers options for mitigation ie reducing greenhouse gas emissions and store carbon. The objective of the study is to explore the optimum level of plant nutrient for sustaining the desired crop productivity in hybrid cotton through optimization of benefit from all possible resources of plant nutrients in an integrated manner and to mitigate the green house gas emission through the adoption of Integrated Plant Nutrition System. The experiment was carried out in three locations with different soil fertility status with special emphasis to nitrogen levels in the soils. The fertilizer doses were fixed based on the soil test values and fertility grouping / indexing by International soil fertility evaluation and improvement programme. As part of organics, FYM was applied at two different levels, and the fertilizers were reduced accordingly. The results proved that application of organic manure @ 12.5 t ha-1 along with the recommended doses of nutrients proved superior in seed cotton production as well reduced nitrous oxide emissions.

Impacts Of Climate Change

The impact of climate change on human and plant nutrition and health is felt worldwide. Rising atmospheric greenhouse gas concentrations, temperature extremes, changes in precipitation, increases in the frequency and density of weather events, and rising sea levels confer severe direct and indirect impacts on human health. The rapid flooding, intensive drought, unpredictable heat-waves including rapid wildfire outbreak has been on the increase exacerbating various chronic diseases and intensifying global cardiovascular heat-stress. Indirect health impacts of climate change may be long-term and might progressively lead to behavioural changes. The field survey was carried out in Calabar and Obubra, where anthropometric measurement of children under five (5) years were carried out. Soil-pant visual assessment for soil-plant nutrition and health was carried out in both Obubra and Calabar. Correlation statistics and analysis of variance (ANOVA) were used to analyze field data. Result of the field survey indicated that climate change can statistically (P˃0.05) damage plant-human health and nutrition. Result analysis output indicated that there exist a relationship between human-soil health/nutrition and climate change. A climatic percentage analysis relationship indicated that human nutrition/health has a (% Relationship = 77.59), plant-soil health interaction (% Relationship = 63.34) which indicated that the climatic system has a strong influence on human-plant-soil survival and sustainability. Findings of the study revealed variation in climatic element of rainfall, temperature and relative humidity of Obubra and Calabar. The study encourages mineral fertilizer application including application of organic amendment, as a targeted strategy for soil improvement to reduce malnutrition. Further aggressive implementation of scientific and traditional strategy and approaches that will enable CO2 and other greenhouse gas emission reduction have been advice for human-soil-crop health and nutrition sustainability.

In recent years much attention has focused on the impacts of agriculture on climate change, due to this stage specialists in plant nutrition and soil fertility have achieved the task of generating adequate fertilization doses for pineapple. A methodology for Integrated System for Recommending Fertilizer Dose, was used. As a result, seven Thiessen polygons, where rainfall ranged from 1640 to 2841 mm was correlated. Therefore, three major soil groups were defined and classified as subunit level. Likewise, eight doses of fertilizers were generated as follows: N, P2O5 and K2O, with a fertilizer dose, a map is generated according to the cultivar: 230-138-300 for Creole pineapple Acrisol Cutánico (Chromic, Ferric); 460-161-480 for Cayenne and MD2 in Acrisol Cutánico (Endoarcíllico, Ferric); 345-161-450 for Cayenne and MD2 and Creole in Acrisol 253-138-450 for Cutánico (Endoarcíllico, Hyperdystric, Ferric); 391-161-450 for Cayenne and MD2 in Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric) and Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric, Ferric); 207-138-300 for Creole in Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric); 253-138-300 for Creole in Acrisol Umbric Cutánico (Endoarcíllico, Hyperdystric, Ferric); 253-138-360 for Creole in Acrisol Umbric Gleyic (Hyperdystric, Ferric); and 391-161-360 in Endogleyic Cambisol (Clayic, Eutric). These fertilizer doses were supplemented with micronutrients to obtain the expected results.

Agricultural Yield

The climate is one of the key elements impacting several cycles connected to soil and plant systems, as well as plant production, soil quality, and environmental quality. Due to heightened human activity, the rate of CO2 is rising in the atmosphere. Changing climatic conditions (such as temperature, CO2, and precipitation) influence plant nutrition in a range of ways, comprising mineralization, decomposition, leaching, and losing nutrients in the soil. Soil carbon sequestration plays an essential function—not only in climate change mitigation but also in plant nutrient accessibility and soil fertility. As a result, there is a significant interest globally in soil carbon capture from atmospheric CO2 and sequestration in the soil via plants. Adopting effective management methods and increasing soil carbon inputs over outputs will consequently play a crucial role in soil carbon sequestration (SCseq) and plant nutrition. As a result, boosting agricultural yield is necessary for food security, notoriously in developing countries. Several unanswered problems remain regarding climate change and its impacts on plant nutrition and global food output, which will be elucidated over time. This review provides several remarkable pieces of information about the influence of changing climatic variables on plant nutrients (availability and uptake). Additionally, it addresses the effect of soil carbon sequestration, as one of climate change mitigations, on plant nutrition and how relevant management practices can positively influence this.

Insect Interactions

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
