Desertification mapping is the first step in tackling this important problem. The failure of mapping to date creates a research gap that needs to be addressed as soon as possible.
荒漠化制图是解决这一重要问题的第一步。迄今为止，地图绘制的失败造成了一个需要尽快解决的研究缺口。

The expansion of agricultural lands in the Thiba River watershed, particularly in the Mwea Irrigation Scheme and other parts of the watershed, has resulted in excessive water abstraction from the Thiba River, thereby reducing its flow and affecting its downstream users. This study aimed to evaluate the potential impacts of the expansion of agricultural lands on the streamflow regime of the Thiba River and its impact on the downstream users by comparing the 2004 and 2014 land uses and simulating the long-term impact using the HEC-GeoHMS and HEC-HMS models. The results showed a considerable decline in the streamflow in the dry months compared to the wet months, with increasing water abstraction trends from 2007 to 2014. The long-term impact assessment showed an average decline in streamflow in the near (2030) and far (2060) future due to land use and population changes with minimal impact from the increasing precipitation. Based on these findings, there is a need for proper water management and adaptation mechanisms to be put in place to maintain the future water supply from the Thiba River. The study's findings could assist policy and decision-makers in making informed water resource management decisions.

This research article aims to establish a relationship between regional conditions of agri-food production and their correlations with macroeconomic structures. To this end, soybeans production in Rio Grande do Sul, Brazil, and its trade with China are observed. The analysis draws on the Food Regimes approach in dialogue with institutionalist theory, especially considering the construction of agricultural production habits and models. The argument takes secondary quantitative data on soybeans production and trade, triangulating them with information gathered from international platforms – primarily FAOSTAT and Trase Platform – and with qualitative data collected during field research – using landscape analysis and interviews conducted with soybean cooperatives (in the Brazilian case). Findings on the formation of the soybean market between Rio Grande do Sul and China reveal historically constituted elements that shaped trade flows as they are configured contemporarily. A correlation between the Third Food Regime and effects on agricultural practice in the Brazilian region was also observed.
