Answers to Frequently Asked Questions

Second- and third-generation biofuels would not affect food sources. Land that is declared by governments as not suitable for agriculture, which is called degraded land, can be used for energy crops. For example, Jatropha curcas, Pongamia pinnata, and other such crops, can grow in degraded land. If degraded land is not used for any purpose, it may become barren land. If the land is used for bioenergy crops, it preserves the ecosystem by generating oxygen, reducing soil erosion, creating habitats (at least for scavengers), and so forth. The food matrix may increase or decrease depending on the types of bioplants.

Water pollution imposes many environmental and human health impacts, as soil productivity will likely decrease, which can cause previously cultivated land to become barren land. Therefore, due to deteriorated quality of water from increased agricultural use upstream, this can create further water quantity issues in Syria and Iraq, as their available water will not be suitable for agricultural or human consumption (Kurdish Human Rights Project, 2002).

Being rich in nutrient value, this soil-like material can be used to amend the quality of barren land or land with low nutrient value. It is also reported that, due to its structural stability, enhanced porosity, and appropriate moisture availability, this aged refuse is capable of improving soil properties, enhancing nutrient transport, and reducing soil erosion (Ziyang et al., 2015).

The type of land use affects erosion processes significantly. Generally, barren areas experience faster erosion versus forest-covered surfaces (Dai et al. 2001). The land use layer in the ENVI® 4.5 software environment was extracted from images of Landsat 8 and this layer was prepared on a scale of 1:100,000. Rangeland and forest cover most of the Abdanan region (Figure 3(j)). The NDVI indicates the amount of vegetation in a region (Dai et al. 2001; Cevik and Topal 2003). The NDVI factor was obtained using images of Landsat 8 in ArcGIS®10.3 software. The values of NDVI factor were measured using Eq. 2 (Pradhan and Youssef 2010) as follows:
