What are the major uncertainties in the allocation of rangelands?
The major uncertainties – and explanation for discrepancies – in these assessments is the allocation of ‘rangelands’: in some regions it can be difficult to accurately quantify how much of rangelands are used for grazing, and how much is free from human pressure. Despite this uncertainty, most analyses tend to converge on an estimate of close to half of habitable land being used for agriculture.

How does market forces affect crop production?
Market forces, changes in farm programs, and changes in technology affect the supply and demand for land used for crop production. Between 1949 and 1969, cropland used for crops decreased by 54 million acres and then peaked at 383 million acres in 1982, when no cropland was diverted through Government-acreage reduction programs. Since 1980, cropland used for crops has been relatively stable, despite significant variation in commodity prices (see ‘ Commodity Prices Vary More Than U.S. Cropland Acreage ‘).

What are the natural enemies of arable land?
Arable land typically harbours communities of polyphagous invertebrate natural enemies, among them many predacious beetles and spiders (Ekschmitt et al., 1997). There has been much concern about their role as biological control agents (e.g. Luff, 1987; Wise, 1993; Nyffeler et al., 1994; Sunderland, 1999 ), and although these generalist predators lack prey specificity, they also prey on pest organisms and can exert a substantial predation impact on given prey groups or pest species in the field ( Symondson et al., 2002; Maloney et al., 2003). However, as spiders and other omnivorous natural enemies prey on a wide range of different prey groups including other predatory arthropods and non-pest organisms, their direct and indirect effects within agro-ecosystems can be manifold and sometimes unpredictable (Wise, 1993; Wise et al., 1999; Symondson et al., 2002 ). Spiders owe their prominent position within the invertebrate community in arable land not only to their predacious nature and their multiple food web links but also to their sheer abundance. Among the invertebrate natural enemies of agro-ecosystems, they belong to the most dominant groups (e.g. Wise, 1993; Ekschmitt et al., 1997; Nyffeler, 2000 ), contributing up to 35–50% to the ground-dwelling invertebrate predators at Research Station Scheyern farm in terms of both individual numbers and biomass ( Filser et al., 1996; Mommertz et al., 1996; Lang et al., 1997; Lang, 1998, 2000 ). Within the framework of the FAM research project the effects of the arthropod predator community, especially of spiders, were studied in experimental enclosures in arable fields with special reference to biological control (cf. Lang et al., 1995). In contrast to the previous sections of this contribution, the focus of the predation studies was put on soil-dwelling spiders rather than on spiders on plants. Epigeal spiders are generally more abundant in fields than foliage-dwelling spiders; thus, their substantial predation effects seemed more likely. On the experimental farm in Scheyern, peak abundances of 20–90 ground-dwelling spiders per square metre were found in fields (Lang, 1998 ), whereas Barthel (1997a) recorded only minor numbers of foliage-dwelling spiders in the Scheyern fields. However, it must be acknowledged that published studies about the densities of spiders of higher strata in arable fields are generally too sparse to depict a general picture. For example, foliage-dwelling spiders can reach densities of up to 25 spiders per square metre in maize fields ( Ludy and Lang, 2004 ), and even relatively small numbers of web spiders on crop plants may nonetheless decrease prey numbers significantly (e.g. Carter and Rypstra, 1995 ).
How does chelation help soil?
Chelation protects metallic ions from precipitation and specific sorption and increases micronutrient availability. The chelation of Fe, Cu, Zn, Mn, and Ni increases their concentration in soil solution and movement to plant roots by mass flow or diffusion. There are a number of naturally occurring chelating agents in soil formed from root and microbial exudates, including oxalic and citric acids. A number of synthetic chelates have also been used to enhance micronutrient availability, including ethylenediaminetetraacetic acid (EDTA), ethylenediamine bis (2-hydroxyphenyl)acetic acid (EDDHA), and hydroxy-2-ethylenediaminetriacetic acid (HEEDTA).
What is a climatic zone?
Climatic zoning and its corresponding maps is the oldest category of zonation where different climates are distinguished based on relatively simple indices calculated by combining temperature and precipitation data. Biological performance of climatic zones could be improved by introducing climatic requirements and limitations of living organisms leading to bioclimatic zoning. Narrowing down for agricultural purposes, a region can be divided into agroclimatic zones (ACZs) based on homogeneity in weather variables that have the greatest influence on crop growth and yield and agroecological zones (AEZs) are defined as geographic regions with similar climate and soils for agricultural production ( FAO, 1978 ). Van Wart et al. (2013) presented examples for different applications of agroecological zoning such as identifying yield variability and limiting factors for crop growth ( Caldiz et al., 2002 ), selection of optimal crop management recommendations at regional scales ( Seppelt, 2000 ), comparison of yield trends ( Gallup and Sachs, 2000 ), determining suitable locations for new crop production technologies ( Araya et al., 2010 ), and analyzing the impacts of climate change on agriculture ( Fischer et al., 2005 ).
What is the most commonly used method in land suitability analysis?
However, the analytical hierarchy process (AHP) is the most commonly used method in land suitability analysis. Any MCDM method is concerned with how to combine the information from several criteria (or factors) to form a single index for suitability assessment.
What is land suitability assessment?
Land suitability assessment requires models for predicting the suitability of lands for different types of agriculture. Multicriteria evaluation methods are developed for estimating suitability of lands for alternative land uses. The same methods could be applied to agricultural lands for evaluation of suitability of croplands for a given crop based on different criteria (e.g., based on climate, soil, water quality, and so on). GIS-based Multi-Criteria Decision Making (MCDM) provides facilities for incorporating MCDM in land suitability analysis. MCDM could be conducted using different methods such as ELECTRE or PROMOTHEE. However, the analytical hierarchy process (AHP) is the most commonly used method in land suitability analysis. Any MCDM method is concerned with how to combine the information from several criteria (or factors) to form a single index for suitability assessment. Sabaei et al. (2015) provided a review on different MCDM methods including AHP.
