Achieving a long-term food security and preventing hunger include a better nutrition through sustainable systems of production, distribution, and consumption. Nonetheless, the quest for an alternative to increasing global food supply to meet the growing demand has led to the use of poor agricultural practices that promote climate change. Given the contribution of the agricultural ecosystem towards greenhouse gas (GHG) emissions, this study investigated the causal nexus between carbon dioxide emissions and agricultural ecosystem by employing a data spanning from 1961 to 2012. Evidence from long-run elasticity shows that a 1 % increase in the area of rice paddy harvested will increase carbon dioxide emissions by 1.49 %, a 1 % increase in biomass-burned crop residues will increase carbon dioxide emissions by 1.00 %, a 1 % increase in cereal production will increase carbon dioxide emissions by 1.38 %, and a 1 % increase in agricultural machinery will decrease carbon dioxide emissions by 0.09 % in the long run. There was a bidirectional causality between carbon dioxide emissions, cereal production, and biomass-burned crop residues. The Granger causality shows that the agricultural ecosystem in Ghana is sensitive to climate change vulnerability.

The impact of energy, agriculture, macroeconomic and human-induced indicators on environmental pollution: evidence from Ghana
Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-03-01)
In this study, the impact of energy, agriculture, macroeconomic and human-induced indicators on environmental pollution from 1971 to 2011 is investigated using the statistically inspired modification of partial least squares (SIMPLS) regression model. There was evidence of a linear relationship between energy, agriculture, macroeconomic and humaninduced indicators and carbon dioxide emissions. Evidence from the SIMPLS regression shows that a 1% increase in crop production index will reduce carbon dioxide em...
The Evaporative Stress Index as an indicator of agricultural drought in Brazil: An assessment based on crop yield impacts

To effectively meet growing food demands, the global agronomic community will require a better understanding of factors that are currently limiting crop yields and where production can be viably expanded with minimal environmental consequences. Remote sensing can inform these analyses, providing valuable spatiotemporal information about yield-limiting moisture conditions and crop response under current climate conditions. In this paper we study correlations for the period 2003-2013 between yield estimates f...

Food is the essential element of human existence; thus the growing, distribution and providing access to food for citizens is one of the most important issues of the cities. World‘s population has been escalating rapidly in the last decades, and many cities still witness a flow of migration from rural areas. One of the major problems of cities is the decrease in the amount of open public spaces and the quality of social and public life of inhabitants; which also causes the lack of experience of outdoor spac...
The relationship between carbon dioxide, crop and food production index in Ghana: By estimating the long-run elasticities and variance decomposition
Sarkodie, Samuel Asumadu; Owusu, Phebe Asantewaa (2017-06-01)
The study estimated the relationship between carbon dioxide, crop and livestock production index in Ghana: Estimating the long-run elasticities and variance decomposition by employing a time series data spanning from 1960-2013 using both fit regression and ARDL models. There was evidence of a long-run equilibrium relationship between carbon dioxide emissions, crop production index and livestock production index. Evidence from the study shows that a 1% increase in crop production index will increase carbon d...
A study on the effects of some soy products on rheological and textural properties of milk chocolate
Yolaçaner, Elif; Öztop, Halil Mecit; Meclis, İzlem Cansu (2018-07-07)
As the consumer expectation for healthy and functional foods is increasing, utilization of many alternative ingredients is proceeding constantly in food production nowadays. Soybean products are among these ingredients since they involve high quality proteins, isoflavones and they are free from cholesterol, lactose and gluten. Chocolate is one of the most widely consumed food products in the world and rheology of chocolate is vital for its quality and production cost. Rheological properties of chocolate are...
