The effects of climate change on cereals yield of production and food security in Gambia
Published December 30, 2015
83-92

Increasingly, empirical evidences are substantiating the effects of climate change on agricultural production is a reality. In the early part of the 20th century many were skeptical about the so-called climate change that is due to global warming. The Intergovernmental Panel on Climate Change (IPCC, 2007) defines climate change as follows: “c...limate change refers to a change in the state of the climate that can be identified by changes in the mean or variability of its properties and that persists for extended periods, typically decades or longer” This study analyses the impact of climate change on cereals production (millet and maize) in the Gambia using a time series data for a period of 46 years (1960 – 2013) at an aggregate level to assess the relationship between climate (temperatures and rainfall,) and non-climate variables fertilizer, area planted respectively and yield. The specific objectives of the research are: (1) How climate change affects the expected cereals (Millet and Maize) output or yield in the Gambia. (2) How the level of output risk within cereals (Millet and Maize) farming is affected? In order to achieve these set objectives, the paper will adopt Just and Pope modified Ricardian production functions for climate change impact assessments (e.g., Chen et al. 2004), the paper will also control for the impacts of regular input factors in the production process. The study used a data set for the Gambia comprising variables relevant for cereals production and climate information from 1960 through 2013. There is strong evidence that climate will affects Maize and Millet; according to the analysis 77% and 44% of the variability in the yield of Maize and Millet respectively is explained by the climate and non-climate variables included in the model. Given the effects of climate variables on cereals production, and increasing climate change vulnerabilities on other food production section, the result of this paper will add voice to the growing call for policy makers to step up funding in research and development in climate change adaptation and mitigation.

Low-carbon innovation policy with the use of biorenewables in the transport sector until 2030
Published December 30, 2015
45-52

The topic of the present study deals with the changes and future trends of the European Union’s climate policy. In addition, it studies the manner in which Hungary’s transport sector contributes to the success of the above. The general opinion of Hungarian climate policy is that the country has no need of any substantial climate policy meas...ures, since it will be able to reach its emission reduction targets anyway. This is mostly true, because the basis year for the long term goals is around the middle/end of the 1980’s, when Hungary’s pollution indices were entirely different than today due to former large-scale industrial production. With the termination of these inefficient energy systems, Hungary has basically been “performing well” since the change in political system without taking any specific steps in the interest of doing so. The analysis of the commitments for the 2020-2030 climate policy planning period, which defined emissions commitments compared to 2005 GHG emissions levels, has also garnered similar political reactions in recent years. Thus, it is not the issue of decreasing GHG emissions but the degree to which possible emissions can be increased stemming from the conditions and characteristics of economic growth that is important from the aspect of economic policy. In 2005, the Hungarian transport sector’s emissions amounted to 11 million tons, which is equal to 1.2% of total EU emissions, meaning it does not significantly influence total transport emissions. However, the stakes are still high for developing a low GHG emission transport system, since that will decide whether Hungary can avoid those negative development tendencies that have plagued the majority of Western European transport systems. Can Budapest avoid the scourge of perpetual smog and traffic jams? Can it avert the immeasurable accumulation of externalities on the capital city’s public bypass roads caused by having road transport conduct goods shipping?

Cross-sector analysis of the Hungarian sectors covered by the Effort Sharing Decision – Climate policy perspectives for the Hungarian agriculture within the 2021-2030 EU programming period
Published December 30, 2015
17-24

Ever since 2012, the EU ETS (European Union’s Emission Trading Scheme), which is the EU’s climate policy was extended to include the ESD (Effort Sharing Decision) sectors’ (agriculture, transport, building) regulations. As its name implies, this mechanism is based off of shared interests and efforts, all in order to reach the climate goal...s. Therefore, analysing the agriculture sector from an environmental viewpoint requires the analysis of related sectors as well, since their performances will have an impact on determining the requirements to be met by the agriculture. Seeing that those primarily present in said sectors are not various firms, but people and public utility management institutions instead, the level of regulations draws from the economic state of the various countries in question (GDP per capita). Therefore, member states like ours did not receive difficult goals until 2020, due to our performance being lower than the average of the EU. However, during the program phase between 2021 and 2030, all nations are to lower their GHG (greenhouse gases) emission, and have to make developments to restrict GHG emission level growth within the ESD, which means we already have to estimate our future possibilities. During the analyses, we will see that analysing agriculture from an environmental viewpoint, without doing the same to their related sectors and their various related influences is impossible. The GHG emission goals determined by the EU have to be cleared by the agriculture sector, but the inputs from transport, waste management and building are required nonetheless.

Proposals for low-carbon agriculture production strategies between 2020 and 2030 in Hungary
Published December 30, 2015
5-15

When viewed from the perspective of climate policy, agriculture as a separate sector is one of the most difficult development areas to assess. One of the reasons for this is the problem of the localization of greenhouse gas emitters, caused by the fact that production takes place in small or dispersed production units. The special circumstance ...that unit production takes place in complex interactive systems (food, feed, energy sources, main products, by-products, etc.) is yet another special factor, which in addition makes it significantly more difficult to measure and identify the GHGs they emit than if they were a uniform production plant. Additionally, there are few sectors outside agriculture where decision-makers encounter such strong opposition and lobby interests when developing limiting regulations. This stems from the fact that following World War II, European decision-makers and the Common Agricultural Policy elevated agriculture to a prominent role whose importance was indisputable. As a result, both climate policy and other measures that would result in any reduction of the priority of the sector are very difficult to implement, since the players involved always reason that limitations would restrict their competiveness and the security of their production. In addition, the uncertain nature of regulatory elements also poses a grave problem. As an example, the name of the sector itself – the LULUCF (Land Use, Land Use Change and Forestry) sector – shows that the strategy for reducing the greenhouse gasses emitted by the whole sector would be significantly different if these units were treated separately (agricultural land use, forest, not-cultivated areas). Taking the above into account, the present study aims to identify development directions that in turn allow those low-carbon development directions to be pinpointed within animal husbandry and plant production that have the greatest feasibility and can contribute to decreasing the GHG environmental load exerted by agriculture.
