Study on the quality improvement on black land in Northeast China under the environment of sustainable agricultural development

PurposeThe authors are committed to providing the Chinese government with a foundation for making decisions that will protect black land and ensure long-term agricultural development.Design/methodology/approachUsing the grounded theory approach, this study investigates the influencing factors affecting the quality of black land in Northeast China and proposes a hypothetical model for the mechanism of the influencing factors on the quality of black land in Northeast China.FindingsThe factors influencing the quality of black land include not only soil quality, ecological quality and environmental quality, but also economic quality and management quality, and can be classified into five categories. There are complex influence relationships between various factors and black land quality, with soil quality, ecological quality, environmental quality and management quality having a positive influence on economic quality. Soil quality, ecological quality and environmental quality are all improved as a result of good management. Black land quality is influenced positively by environmental quality, economic quality and management quality.Research limitations/implicationsThe quality of black land is a major concern in terms of food production and long-term agricultural development. The black land in Northeast China was chosen as the subject of this study, and the research findings have some limitations. The next step will be to expand from studying the black land in Northeast China to the black land worldwide.Originality/valueIn Northeast China, the quality of the five dimensions of black land must be improved in a coordinated and consistent manner.

Dreams of a Black Commons on Turtle Island

This essay opens with a discussion of the Black commons and the possibility it offers for visioning coherence between Black land relationality and Indigenous sovereignty. Two sites of history – Black slavery and Black migration prior to the twentieth century – present illuminations and challenges to Black and Indigenous relations on Turtle Island, as they expose the “antagonisms history has left us” (Byrd, 2019a, p. 342), and the ways antiblackness is produced as a return to what is deemed impossible, unimaginable, or unforgivable about Black life.While the full histories are well beyond the scope of this paper, I highlight the violent impossibilities and afterlives produced and sustained by both – those that deserve care and attention within a “new relationality,” as Tiffany King has named, between Black and Indigenous peoples. At the end of the essay, I return briefly to Anna Tsing’s spiritual science of foraging wild mushrooms. Her allegory about the human condition offers a bridge, I conclude, between the emancipatory dreams of Black freedom and Indigenous sovereignty.

ANALYSIS OF THE BASIC SANITATION SYSTEM OF BLACK LAND EARTH IN MANACAPURU-AM

Due to the adjunct population growth of the Industrial Revolution since the 70's, it has been thought and planned about the adequate urban infrastructure, which is taking into consideration the welfare of the population. From this line of thought, sanitation has become one of the alternatives for municipal development, because besides encompassing sanitation services, it also has interrelationship with other areas such as health, housing, leisure and others. Thus, this article aimed, through the analysis of the basic sanitation system, to facilitate the identification of the current problems in the sector of the black neighborhood in Manacapuru - AM. To this end, discussions were held on the structure of the Municipal Basic Sanitation Plan of the municipality and field measurements were collected for the development of diagnostic maps of basic infrastructure characteristics, such as drainage, water and sewage network, waste collection and junk dumps. Thus, the analysis of the previous and current sanitation situation was carried out. Increases were found in the junk dumps, and in the drainage system's mouths and in the absence of a sewage system. From this the adopted method was efficient for analysis of the basic systems, being able to be used for evaluation of the other districts of the city.

ANALYSIS OF THE CURRENT SITUATION OF IRREGULAR DWELLINGS IN THE BLACK LAND NEIGHBORHOOD OF MANACAPURU-AM: CAUSES AND CONSEQUENCES

The present work aimed to perform an analysis of the current situation of irregular dwellings in the black earth neighborhood of Manacapuru-AM using geotechnologies. The methodology consists in identifying the irregular occupations of the neighborhood, and demonstrating the problems encountered as well as the possible solutions. The information obtained was used to generate the diagnostic maps to analyze the characteristics of irregular dwellings and if they have water and sewage network, waste collection, junk dump and drainage network, because it is a simple technique, it is possible to be used in other neighborhoods of Manacapuru, being extremely important in helping public policy planning and environmental monitoring.
