The United Nations adopted 17 Sustainable Development Goals(SDGs)to address societal,economic and environmental sustainability issues.The efficiency of SDGs monitoring could be improved by essential variables(EVs),which can help to better deal with massive data,interdisciplinary knowledge and workloads.However,in practice,effectively combining EVs with SDGs monitoring remains challenging.In this paper,we proposed a refining method of essential SDGs variables(ESDGVs)to land degradation.Firstly,we selected northwest China as our experimental region and extracted a group of variables related to land degradation from SDG indicators based on the dpsir framework.Next,we identify the essential ones using a combined qualitative and quantitative methods with the criteria of feasibility,spatialization,and relevance which considered the issues of data acquisition,monitoring scale,and closeness to the land degradation.Finally,we analysed the monitoring role of ESDGVs.Results show that,compared to conventional observations,ESDGVs facilitate the monitoring and evaluation of regional SDGs with reduced efforts.And both climate and human activities have a facilitating or inhibiting effect on land degradation processes.In the future,we hope to have more mature data sets and consider adding more SDG indicators for ESDGVs’refinement.

Relying on the conceptual dpsir framework and MODFLOW analysis,this study used a mixed approach to produce groundwater resource management solutions for the Najafabad area in central Iran.According to dpsir results,agricultural activities put the highest pressure on groundwater resources in this region.The results showed the effectiveness of reducing waterwithdrawal over 30 years in maintaining the aquifer in a state of equilibrium.The best scenario consisted of cutting down extraction by 10%over the said period.Output maps of the water table rise at the Najafabad aquifer clearly showed that the groundwater management scenario involving a 10%reduction ofwater withdrawal was the most effective solution,as itwould raise thewater level by 6.7 m.Regarding other scenarios,reducing cultivated area by 20%was found to raise the water table by 5.03 m on average,while cutting down water withdrawal by 5%increased the water table by 3.6 m,and a 10%reduction of the cultivated area resulted in a 1.85mrise.The combinedmodel proposed here can be used for similar aquifers and can aid decision-makers and managers.

Land ecological security(LES)is an important part of China’s ecological civilization construction,which plays a vital role in ensuring the sustainable development of its society and economy.Based on the Driving force-Pressure-State-Impact-Response(dpsir)framework,this study quantified the spatiotemporal changes of LES in 28 counties of the southern Shaanxi Province from 2009 to 2018.The influencing factors of LES in Yangxian County were explored to clarify the mechanisms that rely on the land ecological advantages to develop organic agriculture and boost poverty alleviation.Results show that the LES of Yangxian always ranked in the top six in 28 counties of the southern Shaanxi region during 2009–2018.The LES in Yangxian increased from 0.385 in 2009 to 0.533 in 2018,and the LES level changed from relatively unsafe to safe.The indicators of rural per capita net income,grain output per unit area of arable land,and grazing intensity could explain 99.8%of the LES variance in Yangxian.Relying on ecological resources,Yangxian increased farmers’income and boosted alleviation of poverty through innovative land policies,developing organic agriculture,and rural tourism.These findings will provide theoretical support and model reference for balancing ecological protection and poverty alleviation in restricted development zones.
