“…Remote sensing (RS) usually refers to the efficient utilization of airborne detecting advances for sensing objects on the ground from a distant location through signal transmission from satellites [83,164]. The use of RS in SWM has been done for siting landfills for waste disposal [32], evaluation of the ecological impact of covered waste [125], and monitoring for waste landfill [198].…”

The burgeoning population has endangered the sustainability of urban areas where over half of the total global population will live by 2050. The population growth has increased the rate of waste production noticeably during the recent past. And its disposal and management are a serious environmental problem across the world. The problem is severe in developing nations because of the quick populace rise and urbanization, the absence of funding and policies, and poor and irregular waste management services. Besides, most municipal authorities in developing nations mainly focus on waste disposal and not management. Appropriate management of municipal solid waste (MSW) is essential for accomplishing many United Nations' Sustainable Development Goals (UN' SDGs) such as SDG6 "Clean Water and Sanitation," SDG11 "Sustainable Cities and Communities," and SDG12 "Responsible Consumption and Production." This paper assesses the use of diverse systems engineering models and remote sensing, GIS, and GPS for appropriate disposal and management of MSW issues. All the possible sources of related and up-to-date literature have been accessed and more than 210 publications were collected and thoroughly analyzed for this review. The past literature analysis revealed that the cost-benefit analysis models were used to appraise a waste management system's positive and negative economic effects. In contrast, optimization models were used to reach the best solution among several options, considering a set of objectives. The analysis also revealed that the GPS applications were primarily done for tracking waste bins and collection vehicles for monitoring collection time and location. Moreover, the investigation revealed that the combined applications of GPS and GIS techniques performed better than their specific applications. The analysis of numerous global case studies disclosed that political, socioeconomic, hydrological, geological, and environmental factors should be taken into account for a proper landfill siting.

“…Soil salinity is a challenging environmental problem that affects 20% of the irrigated land worldwide (Qadir et al, 2014;Singh, 2022). Soil salinity reduces productivity not only in crops with high salinity sensitivity as sweet potato, wheat or maize but also in highly tolerant crops as cotton, barley and sugar beet (Zorb et al, 2019).…”

Effects of Combined Abiotic Stresses Related to Climate Change on Root Growth in Crops

Climate change is a major threat to crop productivity that negatively affects food security worldwide. Increase in global temperatures are usually accompanied by drought, flooding and changes in soil nutrients composition that dramatically reduced crop yields. Against the backdrop of climate change, human population increase and subsequent rise in food demand, finding new solutions for crop adaptation to environmental stresses is essential. The effects of single abiotic stress on crops have been widely studied, but in the field abiotic stresses tend to occur in combination rather than individually. Physiological, metabolic and molecular responses of crops to combined abiotic stresses seem to be significantly different to individual stresses. Although in recent years an increasing number of studies have addressed the effects of abiotic stress combinations, the information related to the root system response is still scarce. Roots are the underground organs that directly contact with the soil and sense many of these abiotic stresses. Understanding the effects of abiotic stress combinations in the root system would help to find new breeding tools to develop more resilient crops. This review will summarize the current knowledge regarding the effects of combined abiotic stress in the root system in crops. First, we will provide a general overview of root responses to particular abiotic stresses. Then, we will describe how these root responses are integrated when crops are challenged to the combination of different abiotic stress. We will focus on the main changes on root system architecture (RSA) and physiology influencing crop productivity and yield and convey the latest information on the key molecular, hormonal and genetic regulatory pathways underlying root responses to these combinatorial stresses. Finally, we will discuss possible directions for future research and the main challenges needed to be tackled to translate this knowledge into useful tools to enhance crop tolerance.

Recent ecological perturbations are presumed to be minimized by the application of biofertilizers as a safe alternative to chemical fertilizers. The current study aims to use bioinoculum (I) as an alternative biofertilizer and to alleviate salinity stress in the cultivar Solanum melongena L. Baldi. The salinity drench was 200 mM NaCl (S), which was used with different treatments (0; I; S; S + I) in pots prefilled with clay and sand (1:2). Results showed that salinity stress inhibited both plant fresh and dry weights, water content, and photosynthetic pigments. The content of root spermine (Spm), spermidine (Spd), and puterscine (Put) decreased. However, addition of the bioinoculum to salt-treated plants increased pigment content (80.35, 39.25, and 82.44% for chl a, chl b, and carotenoids, respectively). Similarly, K+, K+/Na+, Ca2+, P, and N contents were significantly enhanced. Increases were recorded for Spm + Spd and Put in root and shoot (8.4-F, 1.6-F and 2.04-F, 2.13-F, respectively). RAPD PCR showed gene expression upregulation of photosystem II D2 protein, glutathione reductase, glutathione-S-transferase, protease I, and protease II. The current work recommends application of the selected bioinoculum as a green biofertilizer and biopesticide. Additionally, the studied eggplant cultivar can be regarded as a source of salt tolerance genes in agricultural fields.
