“…Over the past three years, under the combined impact of national policies and markets, the framework within which the pig breeding industry in China operates has been undergoing great changes, with a large number of medium and small farms and scattered (sanyang) breeding households withdrawing from the market and the market share of large-scale pig breeding enterprises rising (Liu et al, 2021a(Liu et al, , 2021bZhang et al, 2021;Zheng et al, 2021). Pressure to improve environmental protection and industrial transformations is placing scattered breeders, which were formerly the mainstay of the industry, in a dilemma.…”

Over the past three years, under the combined impact of national policies and markets, the landscape of the pig farming industry in China is undergoing great changes, with a large number of medium and small farmers and scattered (sanyang) breeding households withdrawing from the market, and the market shares of large-scale pig breeding enterprises rising. Pressure from environmental protection and industrial transformation is placing the scattered breeding households, which were formerly the mainstay of the breeding industry, in a dilemma. Research and public opinion generally believe that sharp fluctuations in pig prices and environmental pollution from pig breeding are the primary negative effects of the sector and that both are due to the lack of macro control and the nonstandard practices of scattered households. But is this really the case? Drawing on qualitative fieldwork in northern Shanxi, this paper aims to provide a case study of scattered pig breeding and its interaction with environmental protection. Empirical research found that, in this region of Northern Shanxi, where animal husbandry and horticulture are equally important and complementary, pig breeding by scattered households does not put obvious pressure on the environment. Although there is still room for improvement in policy implementation and cooperation among government departments, and so on, pig farming is part of a sustainable agricultural system. Instead of discouraging scattered pig breeding everywhere, policy needs to take local environmental conditions and the relationship between horticulture and livestock rearing into account.

“…Además de incrementar las emisiones de metano y óxido de nitrógeno, dos gei, esos desechos contaminan severamente el agua. La difusión de los fertilizantes químicos, la proximidad de las granjas a las ciudades y su desconexión con la producción de forrajes limitó el tradicional empleo del estiércol como fertilizante, lo que tornó habitual que este fuera arrojado sin tratamiento en lagos y ríos (Lander et al, 2020;Zhang et al, 2021). Es de anotar que el censo nacional sobre la fuentes de contaminación en China de 2010 y su actualización en 2020 identificaron a la producción ganadera como la principal fuente de descarga de nitrógeno y fósforo en los cursos de agua (Bai et al, 2019;Xinzhen, 2020).…”

“…Por otra parte, en suelos fertilizados con estiércol también se detectó contaminación con metales pesados, como zinc y cobre, que son incorporados como aditivos en los piensos (Bai et al, 2019), lo que llevó al Ministerio de Agricultura de China a fijar un límite en el uso de esos metales (Zhang et al, 2021). Otra fuente de preocupaciones asociada a la actividad porcina es el excesivo empleo de antibióticos para enfrentar el hacinamiento de animales genéticamente similares en deficientes condiciones higiénicas y sanitarias (Verzeñassi et al, 2020).…”

“…Como fue señalado, esos peligros se incrementan por las falencias en el manejo de los residuos de la actividad, como lo ejemplifican los 16 000 cerdos muertos a causa de una epidemia en 2013, que fueron arrojados al río Huangpu, que abastece de agua a Shanghái (Lü, 2013;Trápaga Delfin, 2017). La salud humana puede verse comprometida asimismo por el ingreso de los residuos de antibióticos o microorganismos que generaron resistencias a la cadena alimentaria (Schoenmakers, 2020;Zhang et al, 2021).…”

El severo impacto ambiental de los actuales patrones de producción y consumo de alimentos y la pandemia de covid-19 otorgaron una inusitada relevancia a la transformación del sistema agroalimentario a nivel local y global. Este trabajo explora las implicancias de las acciones de China para la protección de su industria porcina tras la epidemia de peste porcina africana, en la trayectoria del sistema agroalimentario global. Para ello se estudió el proyecto de instalación de granjas porcinas en Argentina negociado en 2020. Mediante un diálogo del enfoque neogramsciano de la economía política internacional con los estudios agrarios críticos, se argumenta que esa iniciativa demuestra que, pese a los efectos ambientales y sanitarios, el interés de China no es transformar su modelo de producción porcina, sino trasladarlo hacia nuevos territorios. De ese modo, China reconstruye su liderazgo porcino y afirma su poder dentro del modelo agroalimentario hegemónico.

“…En el mundo las regulaciones ambientales para el manejo de los desechos líquidos y sólidos de las granjas porcinas se han endurecido durante la década de 2010 a 2021. Las consecuencias han sido que las granjas medianas y pequeñas han desaparecido en China (Zhang et al, 2021); en EE.UU. las granjas han sido expulsadas a sus países de origen (Corn et al, 2009;Schmidt, 2009).…”

Introduction: The state of Yucatán is the third national producer of pork meat due to a large number of pig farms, there are them of all sizes from very small to mega-farms with more than 30 000 pigs, many of which generate environmental and social problems. Objectives: The analysis of the operation of pig farms in Yucatán; identification of environmental problems; and proposals for mitigating damage to the environment and human health. Results: The environmental problem is generated by the large amount of water with which they operate to clean the farms and cool the pigs during high-temperature days. In addition to the large volumes of water extraction, large volumes of wastewater are generated that are not properly treated and that contaminate air, soil, and groundwater. In this work, the traditional way of operating farms is documented, emphasizing environmental damage. The particularities of karst landscapes and their environmental vulnerability are explained. Implications: Ways of reducing environmental problems are proposed with the idea that they are taken into account to move towards sustainable management of pig farms in the state of Yucatán, for example, selection of the best sites for pig farming (relief, soils, climate, and depth of groundwater), reduction of extracted water, treatment through artificial wetlands and agricultural use of wastewater through sprinklers in soils of the Luvisol, Nitisol and Vertisol groups. Conclusions: For the transit of contamination to Sustainability in the management of pig farms in the state of Yucatán requires knowledge, innovations to solve problems, social commitment with local communities, and environmental regulations. It will not be easy but it is possible.
