“…In a study carried out by (Upreti et al, 2011) with different crops (onion, potatoes, wheat, radish, rice), using mineral (NPK) and organic fertilizations (human urine), and with distinct spaces, it was observed that human urine positively affected the evaluated crops.…”

Agricultural utilization of yellow waters associated with cassava wastewater is a sustainable technique, since it allows reduction of costs related to acquisition of industrialized fertilizers and minimizes the environmental pollution caused by the inadequate disposal of these effluents. In this context, this study evaluated the macronutrient macronutrient content and growth of cowpea fertigated with yellow water associated with cassava wastewater and NPK as source of nutrients. The experiment was set up in a greenhouse located at Campus I of the Federal University of Campina Grande. The experimental design was completely randomized, composed of five treatments characterized by: fertigation with mineral fertilizers, in the form of NPK; organic fertigation composed of human urine, cassava wastewater, human urine plus cassava wastewater; and organo-mineral fertigation composed of urine, cassava wastewater and mineral phosphorus, with four replicates. At 36 days after sowing, the following parameters were determined: contents of nitrogen, phosphorus, potassium, sulfur and the variables number of leaves, plant height, stem diameter, leaf area, shoot fresh matter and shoot dry matter. The use of yellow waters promotes significant increases for growth and production variables for nitrogen and potassium contents mainly, as well as for growth and production variables. The contents of nitrogen, phosphorus and potassium were higher than the levels considered as adequate for the cowpea crop. The use of human urine and cassava wastewater have potential to meet the needs for the main macronutrients required by cowpea and the irrigation via fertigation with these biofertilizers positively influences the development of cowpea.

“…The firmly held belief that the Pahadi ruling elites misrecognized the Madhesi community and systematically excluded them from the national mainstream served as the foundation for the politics of recognition (Pandey, 2022;Sijapati, 2013). Put differently, historical exclusion and marginalization, and systemic structural discrimination of the Madhesi people set the conditions for the rise of the collective consciousness of a pan-Madhesi identity at the macro-level (Hachhethu, 2007;Jha, 2017;Mathema, 2011;Sah, 2017;Upreti et al, 2013). However, a gradually emerging dissension in the micro-politics of the Madhesi community -the political, economic, and sociocultural cleavages and confrontations posing problems to the pan-Madhesi identity -has not received the attention it deserves in scholarly discourse.…”

“…In Tarai-Madhes, social interactions are governed by caste distinctions, which also heavily influence political decisions and frequently influence economic stratification (ICG, 2007). Caste factors continue to significantly influence local and regional politics (Gaige, 2009;Upreti et al, 2013). While high-castes and some middle castes, such as Yadavs in the Tarai-Madhes, enjoy cultural, political, and economic privileges (Basnet, 2019), low-caste Madhesi have faced indignities of untouchability and social ostracization (Tewari, 2012).…”

A gradually emerging dissension in the micro politics of the Madhesi community has not received the attention it deserves in scholarly discourse. This article makes an effort to understand the contexts and processes that made pan-Madhesi identity intrinsically problematic and seemed to be rife with internal conflicts. Drawing on the lived experiences collected through ethnographic interviews with the Madhesi people who belonged to the low-caste groups and admitted to being poor, it is argued that while overemphasizing the socio-cultural recognition of the Madhesi community, Madhesi politics of recognition undermined the issues of economic inequality prevailing within it for a long time. As a consequence, over time, the ties of low-caste groups with the elitist leadership of high and middle-caste groups in terms of socio-cultural and economic aspects resulted in certain fissures or divisions in the Madhesi community. This prompts us to rethink the Madhesi politics of recognition and to argue that pan-Madhesi identity was not a cohesive identity that guaranteed parity of participation of the Madhesi population irrespective of their caste and class position.

“…The majority of the agents such as bacteria, protozoa, viruses and helminthes in excreta which cause diseases are usually shed in faeces rather than in urine (Hoglund et al 2002). As a result, the health risks which are associated with the consumption of urine for agricultural purposes have been found to be insignificant (Upreti et al 2011). The pathogens which cause venereal diseases can also be excreted through urine but there is no indication of whether they have a potential to thrive outside the human body and if this would be of any health significance (Hoglund et al 2002).…”

Purpose The study assessed trace metal levels in the leaves, stalks and roots of Spinacia oleracea harvested from soil treated with urine in comparison to chemical fertilizers and biosolids. Methods Spinacia oleracea seedlings were planted on soils pretreated with urine, chemical fertilizers and biosolids. Results The soil treated with chemical fertilizers resulted in an increase of Cr, Pb, Cd, Cu, Ni and Sb while there was an increase in the concentrations of Zn and Hg in the soil treated with urine. The soil with no amendments recorded higher mean values of As and Mn, whereas the biosolids treatment did not show any increases of the trace metals in the soil. The concentration of Mn, Pb and Ni in the leaves and stalks of S. oleracea harvested from soil treated with urine were below the recommended limits for trace metals in edible plants as set by WHO even though the urine treatment recorded the highest concentration of Cd in the roots, stalks and leaves. The S. oleracea harvested from the soil treated with chemical fertilizers showed an accumulation Cu and Mn in the stalks and leaves while those harvested from soil treated with biosolids showed an accumulation of Cr, As, Zn and Ni in the stalks and Cr, Pb and Sb in the leaves and all trace metals in the roots except Cd and As. S. oleracea harvested from the soil with no amendments showed an accumulation of Cr, As, Zn and Ni in the stalks and Cr, Pb, Zn and Sb in the leaves. The transfer factor showed that Cd, Zn, Mn and Sn were translocated from the soil to the leaves even though the concentrations were below acceptable limits for human consumption. Conclusions The study demonstrated that the use of urine as a soil amendment may not facilitate or increase the bioavailability of trace metals in the plant tissues.
