This document presents proposals for the design and implementation of a Baseline Survey for the UN Convention to Combat Desertification (UNCCD). It has been prepared at the request of the Secretariat of the UNCCD. The Baseline Survey is to be initiated as part of the UNCCD's Ten Year Strategic Plan, and will form the starting point for monitoring long-term trends in desertification so that prog...

haraz-ghareh su is one of the seven sub-basins of the caspian basin, located on the southern shores of the caspian sea, and as such, is in danger of water crisis due to absence of proper systematic policy and strategy. in this study, the pressure factors on the haraz-ghareh su water resources were identified using dpsir model. then, the pressure parameters on the freshwater resources in the cas...

the aim of this study is to evaluate the obstacles due to a dpsir model combined with fuzzy analytic hierarchy process technique. hence, to prioritize the responses regarding the driving forces, pressures, states and impacts, the hierarchy of the model is established. evaluations and prioritization of model results of urban transport situation in tehran have provided a number of necessary issue...

maharlou-bakhtegan catchment in the southern part of iran is faced with water scarcity.this problem is exacerbated by environmental degradation, climate change effects, mismanagementof water resources, along with a major dependence of water demand supplies on the limitedgroundwater resources. in this study, a combined approach of dpsir model along with the scenarioanalysis was employed to deriv...

Human habitat change is a complicated issue that many factors play different roles in its formation and distribution. Considering this complication, a more comprehensive and holistic approach is needed for a better understanding and management of those factors. The causal frameworks are among systemic and integrated methods for addressing the causes of environmental problems and the relationshi...
