Climate Change Effects

Climate change and food security are complex global issues that require multidisciplinary approaches to resolve. A nexus exists between both issues, especially in developing countries, but little prior research has successfully bridged the divide. Existing resolutions to climate change and food security are expensive and resource demanding. Climate modelling is at the forefront of climate change literature and development planning, whereas agronomy research is leading food security plans. The Benin Republic and Nigeria have grown and developed in recent years but may not have all the tools required to implement and sustain long-term food security in the face of climate change. The objective of this paper is to describe the development and outputs of a new model that bridges climate change and food security. Data from the Intergovernmental Panel on Climate Change’s 5th Regional Assessment (IPCC AR5) were combined with a biodiversity database to develop the model to derive these outputs. The model was used to demonstrate what potential impacts climate change will have on the regional food security by incorporating agronomic data from four local underutilized indigenous vegetables (Amaranthus cruentus L., Solanum macrocarpon L., Telfairia occidentalis Hook f., and Ocimum gratissimum L.). The model shows that, by 2099, there is significant uncertainty within the optimal recommendations that originated from the MicroVeg project. This suggests that MicroVeg will not have long-term success for food security unless additional options (e.g., new field trials, shifts in vegetable grown) are considered, creating the need for need for more dissemination tools.

Global warming is the increase in the average temperature of the Earth’s surface. According to the IPCC (Intergovernmental Panel on Climate Change) average temperature of the Earth’s surface was global warming is the increase in the average temperature of the 0.74 ± 0.18 0C (1.33 ± 0.32 F) over the last hundred years. The impact of rising temperatures is the climate change effect on agricultural production. If the community does not craft made adaptation to global warming will have an impact on food security. This research aims to know the society’s adaptation to food security as a result of global warming and to know the influence of global warming on food security. The research was carried out based on survey methods. The influence of global warming on food security is identified with a share of household food expenditure and the identification of rainfall. Sampling was done by random sampling. The Data used are the primary and secondary data. Primary Data obtained through structured interviews and depth interview using a questionnaire while the secondary data retrieved from publication data of the Central Bureau Statistics B(BPS), Department of Agriculture and Climatology Meteorology and Geophysics (BMKG). The expected results of the study is to know variations of food security due to global warming in Kulon Progo Regency. Comprehensive knowledge through community participation and related Government increased food security that is used as the basis for drafting the model society’s adaptation to the impacts of global warming.

The Impact

Understanding how climate change accelerates or slows down the process of material deterioration is the first step towards assessing adaptive approaches for the preservation of historical heritage. Analysis of the climate change effects on the degradation risk assessment parameters like salt crystallization cycles is of crucial importance when considering mitigating actions. Due to the vulnerability of cultural heritage in Iran to climate change, the impact of this phenomenon on basic parameters plus variables more critical to building damage like salt crystallization index needs to be analyzed. Regional climate modelling projections can be used to asses the impact of climate change effects on heritage. The output of two different regional climate models, the ALARO-0 model (Ghent University-RMI, Belgium) and the REMO model (HZG-GERICS, Germany), is analyzed to find out which model is more adapted to the region. So the focus of this research is mainly on the evaluation to determine the reliability of both models over the region. For model validation, a comparison between model data and observations was performed in 4 different climate zones for 30 years to find out how reliable these models are in the field of building pathology.

AbstractMiddle East, like North Africa, is considered as arid to semi-arid region. Water shortages in this region, represents an extremely important factor in stability of the region and an integral element in its economic development and prosperity. Iraq was an exception due to presence of Tigris and Euphrates Rivers. After the 1970s the situation began to deteriorate due to continuous decrease in discharges of these rivers, are expected to dry by 2040 with the current climate change. In the present paper, long rainfall trends up to the year 2099 were studied in Sinjar area, northwest of Iraq, to give an idea about its future prospects. Two emission scenarios, used by the Intergovernmental Panel on Climate Change (A2 and B2), were employed to study the long term rainfall trends in northwestern Iraq. All seasons consistently project a drop in daily rainfall for all future periods with the summer season is expected to have more reduction compared to other seasons. Generally the average rainfall trend shows a continuous decrease. The overall average annual rainfall is slightly above 210 mm. In view of these results, prudent water management strategies have to be adopted to overcome or mitigate consequences of future severe water crisis.

Many nations have recognized the need to reduce the emissions of greenhouse gases (GHGs). The scientific assessments of climate change of the Intergovernmental Panel on Climate Change (IPCC) support the need to reduce GHG emissions. The 1997 Kyoto Protocol to the 1992 Convention on Climate Change (UNTS 30822) has now been signed by more than 65 countries, although that Protocol has not yet entered into force. Some 14 of the industrialized countries listed in the Protocol face reductions in carbon dioxide emissions of more than 10% compared to projected 1997 carbon dioxide emissions (Najam & Page 1998).

Abstract The agriculture industry has undergone many developments that embraced automation, agro-chemical fertilizers, genetically modified organisms etc that brought exponential growth in productivity post industrial revolution. This growth resolved the food availability issues on a global scale, but rapid climate change has brought about a shift in production practices to more sustainable organic farming techniques from the conventional methods. The climate change effects and increase in greenhouse gas emissions adversely affected the overall agricultural output. The widespread perception is that adoption of organic farming can reduce the harmful greenhouse emissions and be less damaging to the environment, although expecting the same level of productivity as conventional farming is challenging. This gradual shift can cause future food security problems such as availability and affordability of food in developing countries. This article compares and analyses such trend in the Visegrad group (V4) and India. The comparison between a group of developed nations and a developing nation is of exploratory interest because V4 countries are regarded as high-income countries and they are leaders in organic cultivation practices since the 1980s, whereas India as a developing country has seen substantial conversion of agriculture land area from conventional to organic farming in the past decade.

The signals of global warming are now being observed throughout the world. Data of hydrometeorological centres show a significant increase of temperature in many regions accompanied by intense frequency of dry periods. Some substantial and direct effects of climate change may be already noticed at present time. Over the next several decades they will be observed in agriculture. Increase of temperature and reduction of precipitation volumes will probably lead to decrease the level of yield. These changes can significantly affect the global food security. Ukraine is known for its fertile soil and agricultural products, so it has a huge agricultural potential, contributing, in fact, to the global food security. However, the observed weather changes, increase of average temperature and uneven distribution of rainfalls can result in sharp transformation of most of agricultural and climatic zones of Ukraine. According to international processes there is an urgent need for improvement of adaptation to climate change of some branches of national economy of Ukraine, including of agriculture. Expanding the range of types of millet used in agricultural production is an economically feasible process that should be implemented in view of significant climate changes resulting in global warming which is widely discussed in scientific literature. Rapid introduction in crop shifts of the millet that is able to withstand recurring periodic droughts, especially in the southern regions, is one of the ways allowing to overcome the consequences of such extreme conditions. Conditions of the southern regions are favourable for millet crop. Millet is one of the most drought-resistant and heat-resistant crops that can sustain heat injuries and seizures and this is very important for arid areas during dry years, when other crops significantly reduce the level of yield. We studied changes of agro-climatic resources and agro-climatic conditions for formation of millet productivity for various periods of time. The analysis of climate change trend was performed through comparing of data as per climatic scenarios A2 and A1B and of average long-term characteristics of climatic and agro-climatic indicators. The comparative description of millet productivity under the conditions of climate change as per average long-term data (1986-2005) and as per scenarios A2 and A1B of climate change (2011-2030 and 2031-2050) was also performed.

Food And Nutritional Security

In a region characterized by chronic food insecurity and extremely high rates of malnutrition, the projected impact of global climate change on nutritional outcomes is likely to have synergistic effects, compounding the already poor nutritional status of the Sahelian population. Various studies of nutrition among children under five underscore the significant role that animal-source foods play in long-term childhood development and growth. Given the intimate relationship between livestock and people throughout the Sahel, these findings hold important implications for nutritional security in the region. This chapter examines the food security and consumption patterns of the Sahel, mechanisms by which climate change may exacerbate the current situation, and the role of livestock in the future nutrition and food security of the Sahel.
