The objective of this research is to examine the role of economic growth, technology innovation, and renewable energy in reducing transport sector CO2 emission in China by using the annual data of 1990–2018. An application of the QARDL approach discloses that economic growth, technology innovation, and renewable energy significantly influence CO2 emission in the transportation sector in China. Both renewable energy consumption and innovation show a negative impact on emissions of CO2 related to transport. It depicts that due to the increase in renewable energy and innovation, the CO2 emission in the transport sector is likely to decrease; however, an increase in the GDP of a country will upsurge the emission of CO2 in the transportation sector. However, China should make new policies to introduce innovation in the transportation sector to minimize the emission of CO2.

Climate change and variability are a major threat to the agricultural sector globally. It is widely accepted that the changes in temperature, rainfall patterns, sea water level and concentration of CO2 in the atmosphere will have the most devastating impacts on agricultural production. This paper examines the past and future crop production and food security in Kenya under variable climate. From the review, it is evident that the country is already experiencing episodes of climate change, manifested by seasonal changes in precipitation and temperature of varying severity and duration despite overreliance on rain-fed agriculture. The findings also reveal that climate change would continue to negatively affect crop production and food security to the already vulnerable communities in the arid and semi-arid areas. Future projections also indicate that climate variability will likely alter cropping patterns and yields in several regions. As the country is faced with a high population growth rate and rapid urbanization, crop production and food security systems need to become more adaptive as uncertainties of projected climate variability and change unfold. This study is important in providing decision makers and interested stakeholders with a detailed assessment of climate impacts and adaptation strategies geared towards improved crop production and food security.

Adaptation barriers and strategies towards climate change: Challenges in the agricultural sector

This article aims to assess the impacts of climate change towards the achievement of Sustainable Development Goal number two (SDG 2) as well as examining the poverty alleviation strategies by subsistence farmers in South Africa. Widespread hunger and poverty continue to be among the most life-threatening problems confronting mankind. Available statistics show that global poverty remains a serious challenge around the world. Across the globe, one in five people lives on less than $1 a day and one in seven suffers from chronic hunger. Similarly, the developing world is adversely affected by poverty and hunger. In the sub-Saharan Africa, research has revealed a higher prevalence of hunger, malnutrition, poverty and food insecurity. SDG 2 focuses more on eliminating hunger and promoting sustainable agriculture. The study employed an exploratory design and a qualitative method. Snowball sampling was used in selecting relevant sources which led the researchers to other research work on the same field through keywords and reference lists. The researchers employed discourse analysis to analyse data. The study discovered that there are numerous potential effects climate change could have on agriculture. It affects crop growth and quality and livestock health. Farming practices could also be affected as well as animals that could be raised in particular climatic areas. The impact of climate change as well as the susceptibility of poor communities is very immense. The article concludes that climate change reduces access to drinking water, negatively affects the health of people and poses a serious threat to food security.

Tax Revenue and Economic Growth: A Study of Nigeria and Ghana

This paper examines the economic impact of climate change (CC) on food security and agricultural productivity in Sub Saharan Africa (SSA). It examine the impact on the basic components of food security; availability, accessibility, affordability, preference, utilization and nutritional value and food system stability. The so-called “greenhouse fertilization effect” produces local beneficial effects where higher levels of atmospheric CO2 stimulate plant growth. This occur primarily in temperate zones, with yields expected to increase by 10 to 25 percent for crops with a lower rate of photosynthetic efficiency (C3 crops), and by 0 to 10 percent for those with a higher rate of photosynthetic efficiency (C4 crops), assuming that CO2 levels in the atmosphere reach 550 parts per million. the European heat wave of 2003, when temperatures was 6 oC above long-term means, crop yields dropped significantly, by 36 percent for maize in Italy, and by 25 percent for fruit and 30 percent for forage in France. Increased intensity and frequency of storms, altered hydrological cycles, and precipitation variance also have long-term implications on the viability of current world agro ecosystems and future food availability. Climate change has been described as the most significant environmental threat of the 21st century. Wetter climates and more floods are predicted for parts of East Africa and Latin America. Agricultural productivity in Africa, Asia and Latin America is expected to decrease by as much as 20%. In 2004, agriculture directly contributed about 14% of global anthropogenic greenhouse gas (GHG) emissions, according to the Intergovernmental Panel on Climate Change (IPCC). Agriculture is particularly vulnerable to climate change. Projections to 2050 suggest both an increase in global mean temperatures and increased weather variability, with implications for the type and distribution of agricultural production worldwide. One successful path to tread is to boost agricultural production. Projections based on population growth and food consumption patterns indicate that agricultural production will need to increase by at least 70 percent to meet demands by 2050

This study examines the impact of taxation on investment and economic growth in Nigeria from 1980-2010. The ordinary least square method of multiple regression analysis was used to analyze the data. The annual data were sourced from the central bank of Nigeria statistical bulletin and NBS. The result of the analysis showed in conformity to our prior expectation because the parameter estimates of corporate income tax (CIT) and personal income tax (PIT) appears with negative signs, this means that an inverse relationship exist between taxation and investment. The economic implication of the result is that a one percent (1%) increase in CIT will result in decrease in the level of investment in Nigeria. Consequently, an increase in PIT will result in decrease in the level of investment. Finally, the result therefore showed that taxation is negatively related to the level of investment and the output of goods and services (GDP) and is positively related to government expenditure in Nigeria. We also observed that taxation statistically is significant factor influencing investment, GDP and government expenditure in Nigeria. Based on the result of our findings, it is recommended that the government of Nigeria should use taxation to achieve its set target that will enhance economic growth and development.

The Impact of Taxation on Investment and Economic Development in Nigeria

The Nigerian capital market has witnessed obvious transformation over the years, evident by the increased level of participation of the private and public investors at the floor of the stock exchange and in various public offers of quoted companies. The emerging market has also attracted and embraced the attention and the interest of international investors, thus increasing capital inflow. The overall market capitalisation had risen from 1,698.1 million naira in 1980 to 7030.8 billion naira in 2009, thus signifying an increase within the period. Transaction at the floor of NSE has risen to a total of 685716.2 million naira in 2009 from a previous value of 16.6m recorded in 1970. From the result obtained, capital market has positive and significant impact on economic growth in Nigeria. The capital market variables captured in the model such as market capitalization, number of deals and value of transactions were all positive and significant in promoting economic growth in Nigeria. It is important that the government should implement policies that will make the market more efficient and re-position it for growth within the Nigerian economy. Keywords: Capital Market, Economic Growth, Stock Exchange, Market Capitalisation.

The Impact of Capital Market and Economic Growth in Nigeria.

This empirical study examined oil revenue and economic growth in Nigeria between 1981 to 2014. Secondary data on gross domestic product (GDP), used as a proxy for economic growth; oil revenue (OREV), and government expenditure (GEXP) which represented the explanatory variables were sourced mainly from CBN publications. In the course of empirical investigation, various advanced econometric techniques like Augmented Dickey Fuller Unit Root Test, Johansen Cointegration Test and Error Correction Mechanism (ECM) were employed and the result reveals among others: That all the variables ware all stationary at first difference, meaning that the variables were not integrated of the same order justifying cointegration and error correction mechanism test. The cointegration result indicated that there is long run relationship among the variables with three cointegrating equation(s). The result of the error correction mechanism (ECM) test indicates that all the variables except lag of government expenditure exerted significant impact on economic growth in Nigeria. However, all the variables exhibited their expected sign in the shortrun but exhibited negative relationship with economic growth in the longrun except for government expenditure, which has positive relationship with economic growth both in the longrun and shortrun. The study concluded that Government should use the revenue generated from petroleum to invest in other domestic sectors such as Agriculture and manufacturing sector in order to expand the revenue source of the economy and further increase the revenue base of the economy.
