The proper use of natural resources can preserve these valuable assets. In line with the management of natural resources, land use optimization can be highly useful. The aim of the present study is to propose an appropriate integrative model for optimized allocation of lands for surface runoff and sediment load minimization and net income maximization in Bayg watershed, Iran. In this study, fiv...

The production of rainfed crops in arid regions is an extremely difficult task, especially without tillage. In southern Kazakhstan, 2020–2021, the approbation various nutrition regimes for winter wheat grown conditions no-tillage lands has been studied. effect different doses and terms application growth stimulators, micronutrients, bio-fertilizers mineral fertilizers, as well their economic ef...

The main objective of this study is to present an improved modeling technique called Vegetation ET (VegET) that integrates commonly used water balance algorithms with remotely sensed Land Surface Phenology (LSP) parameter to conduct operational vegetation water balance modeling of rainfed systems at the LSP’s spatial scale using readily available global data sets. Evaluation of the VegET model ...

Temporal NDVI signatures of the following land cover types in the Aral Sea Basin (ASB) were analyzed in MODIS data 2000–2012: Wetlands, bare land, water surfaces, natural vegetation and rainfed agriculture (in mountainous regions), low vegetation, rice cropping systems. Only the last class refers to cropland. All other classes were targeted to separate non-cropland or rainfed agriculture from t...

An approach is proposed in the present study to estimate soil erosion data-scarce Kokcha subbasin Afghanistan. The Revised Universal Soil Loss Equation (RUSLE) model used erosion. satellite-based data are obtain RUSLE factors. results show that slight (71.34%) and moderate (25.46%) dominated basin. In contrast, high (0.01%) insignificant area. highest amount of observed Rangeland (52.2%) follow...

Face clustering is a task to partition facial images into disjoint clusters. In this paper, we investigate a specific problem of face clustering in videos. Unlike traditional face clustering problem with a given collection of images from multiple sources, our task deals with set of face tracks with information about frame ID. Thus, we can exploit two kinds of prior knowledge about the temporal ...

Gameplay in real-time strategy games seems somehow to be confined to a de facto standard where economical micromanagement is equally important as combat strategy, if not more important. To enable stronger combat-oriented gameplay without sacrificing other key aspects of the genre, we propose an automated system for scheduling unit training, which we believe may allow the exploration of new para...

Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi- arid soil is, however, limited. This study was carried out to investigate the effects of tillage direction on soil, water, nitrogen and phosp...

In recent days, the land area utilized for agriculture is getting reduced day to due rapid urbanization. The main objective of work identify barren/unused lands that can be used purpose using remote sensing and geographic information system, so there will not losses improper site selection. suitability was assessed on five criteria; type soil, climate, slope percentage, rainfall wells distribut...

Water deficit is an important factor limiting crop growth all over the world. In order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. The experiments were carried out at the Agricu...
