“…They concluded that there is possible diversion of labour and land to bio-fuel and competition of input that led to reduction of food production and high food prices (Teweldemedhin & Mwewa, 2013 , data (1979-2003) of the selected crops discovered that, "the production of biofuels would impact negatively on food production as fuel, food and industries compete for available crop stocks thereby …”

A B S T R A C TUsing crops for fuel generates concerns over competition with food uses. In 2008 a global food crisis hit the world during a record-high commodity and energy prices that prompted hunger and political unrest in developing countries. This took place at the same time when biofuel production, reached its pinnacle in developed countries. This paper examines the effect that biofuel prices and or production has had on food prices in Brazil and United States (U.S.) by employing the panel cointegration and Dynamic Ordinary Least Squares (DOLS) method of analysis. In regressing food prices as a function of demand and supply factors, such as oil prices, biofuel prices, interest rates and biofuel production, the study found that the increase in biofuels production over the past eighteen years has had a significant impact on food prices. Over the period January 1995-December 2013, the study estimates that a one hundred percent increase in biofuels production across time and between countries results in the increase of food prices by 21,9%. The study therefore rejects the null hypothesis that states, biofuel production does not have a statistically significant negative impact on food prices in U.S. and Brazil, and accepts the alternative that biofuel production does have a statistically significant negative impact on food prices in U.S. and Brazil. Other predictors of food prices that the study revealed as significant were oil and interest rates. Policy recommendations for other countries like South Africa are therefore, made based on the results obtained.

“…b. Agro-based residues are very essential in natural replenishing cycle of soil, and the continuous removal of crop residues will affect soil fertility, expose the soil to erosion, and poise a raising risk for food security. This may put pressure on global socioeconomic stability, especially to the less economically endowed regions of the world (Perlack et al 2005;Teweldemedhin and Mwewa 2014). c. Extracting biodiesel from oilseeds would create a shortfall for vegetable oil demands essentially needed for human consumption (Tariyal et al 2013).…”

The rapid increase in demand for energy efficiency and sustainability in recent years, the ecofriendly and renewable sources of energy have taken the center stage by replacing the fossil-based energy resources as they associated with serious environmental and health-related issues. These negative factors ignite to rethink and global shift towards a more carbon-neutral source of energy that is biodegradable, sustainable, and ecofriendly. Agro-based materials from crops and post-harvest residues are currently being explored to meet these challenges as primary feedstock for the production of ethanol, agrochemicals, and biodiesel. However, the cultivation of oilseed crops and other cash crops essentially for biodiesel production will avertedly water down on food supply and security and thus we report in this chapter an ideal alternative source of energy derived from microalgae that hold great promise for the future. Cultivation of microalgae will not compete with food productions and fodder demands, can be cultivated anywhere, will not compete with arable land, has simple growth cycle that can produce lipids all year-round under short period of time requiring less water, and has metabolic pathways that establish atmospheric carbon-neutral effect and balance. With this, the aim of the current chapter is to discuss the potentials of microalgae as third-generation energy source, focusing basically on simple taxonomy, lipid biosynthesis, and various cultivation methods. We also reviewed some simple principles used for the optimization of lipid content in microalgae under various lipid-induction techniques and a brief look into the biosequestration characteristics of microalgae. Furthermore, various methods involved in harvesting and extraction of lipid from microalgae and the chemistry for I. B. Bwatanglang et al. 342 the conversion of lipid extracted from microalgae into biodiesel following simple transesterification process are equally touched at the surface in this chapter. Based on the aforementioned, this chapter comes to conclusion elucidating algae lipid metabolism and production as key fundamentals to consider towards achieving the most desired global energy demand that is sustainable and ecofriendly.

“…This meant that farmers were either not going to find any markets for their farm produce or the market offer price may be very low. According to [49], low prices have usually been offered for Jatropha seed. In any business, markets and market information are two important components.…”

“…The Zambian government has an Energy Regulation Act of 2008 and a Board to regulate production and utilization of biofuels [49]. However, the Act needs reviewing as it is outdated and there has also been no coordination and monitoring of Jatropha projects on the part of the government [52].…”

Forest products, wood and non-wood, remain vital among smallholder households in Zambia with charcoal being the most sought after product. This has led to increased exploitation of forest trees to meet the needs for fuel wood, among others. However, Jatropha curcas plant has been identified as a potential fuel source. In the early 2000s, profit-making organizations encouraged smallholder households to grow Jatropha for use as an alternative fuel source. This paper reports on a study conducted in Solwezi between 2011 and 2014 to evaluate the impact of Jatropha cultivation for biofuel production. A sample of 100 small-scale farmers involved in Jatropha cultivation and key informants were interviewed to evaluate the impact of growing Jatropha at the small-scale level. Results show that farmers lost out on time; income from sale of edible non-wood forest products; and experienced reduction in maize (Zea mays) and bean (Phaseolus vulgaris) production, worsening household economic conditions. Farmers attributed this loss to unclear policy alignment on biofuel production by government. We therefore recommend that project implementation should involve interactions of all legislative bodies and any other concerned stakeholders. There is also a need to promote the value chain, from production to marketing, which focuses on minimizing detrimental effects on the livelihood of small-scale farmers.
