Abstract： Poverty eradication is one of the sustainable human development goals, and is also the important index of human social progress. The study investigates the evolution process of the world poverty and points out the spatial-temporal uneven pattern of the world poverty reduction. The current challenges to the world poverty reduction include aggravated resources exploitation in Sub-Saharan Africa, worldwide forcibly displaced people who lower down poverty identification accuracy, and rural decline which leads to instable poverty reduction. Oriented by the UN’s poverty eradication goal by 2030, the study proposes to strengthen worldwide poverty reduction collaboration, to promote national and regional development transformation, and to revitalize the world's countryside, so as to support world poverty reduction.

Abstract： China is among the most affected countries in the world in terms of the extent, intensity, and economic impact of sandification. Sandy land area is crucial for ecological civilization construction and regional poverty alleviation and development. Sandy land controlling and utilization measures and relative water saving technologies were summarized in this study. Previous studies mainly focused on the native sandy land while ignoring the water saving study of new consolidated land in the context of sandy land consolidation engineering. Sandy land consolidation and agricultural development in Yulin area were studied to clarify the improvement of soil water retention and holding capacity based on the field engineering of mixing red clay with sand. Results show that irrigation water of maize, soybean, and potato can be saved by 41.72%—61.49%, 25.57%—34.43% and 63.92%—70.05%, respectively. Coupling and efficient utilization of water and soil resources can be achieved by integrating sandy land consolidation engineering with cropping pattern optimizing and modern irrigation technologies applying in water resource constraint areas. Future research fields are suggested from the perspectives of modern agricultural development, socio-economic development, ecological civilization construction, and suitability evaluation.

Abstract： Strengthening human resilience against disasters’ disturbance plays an important role in realizing the UN sustainable development goals. The study investigates the occurrence and evolution of major natural disasters and diseases in the world during the past century. It finds out that the major disasters gained frequency and impact after human entering the 21st century. Further, it indicates that the distorted human-nature relationship, rural decline and poverty in Sub-Sahara Africa, globalization have escalated the impact of major disasters. Finally, we propose ways to improve the resilient capacity of human being in terms of multiple perspectives.
