Agricultural density is defined as the number of farmers per unit area of farmland. Agricultural density = (Total number of farmers) / (Total area of... Learn more about this topic: Population Density | Definition, Measurements & Examples ...
Then the provinces of China are divided into four regions, and the differences between regions and the sources of the differences are analyzed using the dagum Gini coefficient and the kernel density method. Finally, Moran's index is used to analyze the degree of spatial aggregation of coordinated...
Furthermore, we used soil organic carbon as it is shown to impact yields36 and to be a good indicator for soil degradation37. For that we used organic carbon density (hg m−3) from SoilGrid v235 for the topsoil (0–30 cm). We aggregated this and soil N from 1 km to 5...
the paper assesses (i) farmers’ capacity to respond to price changes by substituting inputs; (ii) the optimality of the scale of production; and (iii) the optimal utilization of land. As differences in soil quality may alter the size of utilized land and ...
Fig. 1. Household density and program eligibility. Next, using both pre-treatment and post-treatment data, we examine if households on either side of the threshold are similar on a variety of characteristics. First, using the BRAC survey we check for discontinuities in covariates such as age ...
The no-tillage practice is also one of the most popular tillage operations to control soil erosion. The no-tillage practice is a practice that keeps the natural physical soil properties of the whole soil layer that allows microbial and biotic activities to increase the infiltration, bulk density,...
The assessment is based on the maximum of bulk density attained using the Proctor test (MBD). In this study the soil texture is expressed by silt plus clay (S + C) or clay (C). The relations between the soil texture and MBD, and between soil texture and critical water content (CWC—...

The region with the highest population density at the foothill of the mountain was more likely to face a further enhanced agricultural drought (Extended Data Fig. 7). Superimposed onto the external forcing, the IPO evolution not only has intensified the decreasing tendency of soil moisture during ...
Population density is an important factor in malaria epidemiology and the process of urbanization and accompanying demographic change is associated with decreased risks of infection due to reduction of suitable breeding grounds for malaria vectors through reduction of vegetative cover, water surfaces and ot...
