  • Essay / The issue of water supply for cultivation

    Table of contentsWater requirements for biofuel cropsAccording to Food and AgricultureLincoln Way Energy Water supply for cultivation has become a major problem in terms of increasing scarcity in many countries due to increased competition with domestic or industrial industries. used. This problem could also contribute to the adverse effects of climate change in terms of reduced rainfall in some key producing regions, putting additional pressure on local water supplies. (Food and Agriculture Organization of the United Nations, 2008) Regarding the main topic, the production of biofuels requires water supply for both the expansion of raw materials, especially for food crops such such as corn, sugar cane, soya, oil palm and many others. also in the transformation of raw materials into biofuels.

(Food and Agriculture Organization of the United Nations, 2008) Since most crops are currently used for biofuel production, they require high water consumption to achieve the required yield levels that are suitable for the best in topical areas with high rainfall. The table below describes the water requirements for biofuel crops.Water requirement for biofuel cropsFurthermore, water is needed not only for the raw material, but also for the production facilities, especially in biorefineries. Facilities that produce biofuels require water of high purity, largely from the confined aquifer. (Pool, 2014) This can clearly have a further impact on unsustainable pumping which will ultimately not allow future generation to use this aquifer. Additionally, processing feedstocks into biofuels involves huge amounts of water, mainly to clean plants and seeds. Evaporative loss from cooling towers and evaporators during ethanol distillation and followed by fermentation could also contribute to high water consumption. (Water Implications of Biofuel Production in the United States, 2008). Consequently, this will have a greater impact on local water resource balances. According to the Food and Agriculture Organization of the United Nations (2008), the growth prospects of irrigated areas could appear high in In some sectors, due to water supply and land, the particular possibilities of Increased biofuel production under irrigated conditions on existing or new irrigated land is limited by infrastructure requirements. This involves ensuring water supplies and land tenure systems that will not adapt to commercialized production systems. Figure 1 below illustrates the potential for expansion of irrigated areas. Increased production of biofuel crops will affect water quality as well as its quantity. For example, converting pasture or woodland to corn fields can worsen problems such as soil erosion, sedimentation, and excess nutrients from fertilizer use. (Food and Agriculture Organization of the United Nations, 2008) Since fertilizers are..
