Efficient water use is the key for sustainable management of water resources. The major reason of non-efficient management of water resources, especially in developing countries, is nonavailability of reliable hydrological information about the actual water used by different agricultural crops with in a large irrigation system or at the basin scale. Therefore, an estimation of spatially distrib...
The rapid increase of paddy field acreage has led to widely descending of groundwater table in well irrigation paddy area of low-land in Sanjiang Plain recent years. More and more “hanging pump” and partial over pumping phenomenon have been occurring in well irrigation paddy area of low-land. Therefore, the groundwater resources in Sanjiang Plain need to be recharged urgently. For solving the m...
This commentary examines how specific sustainable development goals (SDGs) are affected by antimicrobial resistance and suggests how the issue can be better integrated into international policy processes. Moving beyond the importance of effective antibiotics for the treatment of acute infections and health care generally, we discuss how antimicrobial resistance also impacts on environmental, so...
The increasing interest towards climate change, water and energy saving, and soil protection has led the research community to consider non-conventional water as a sustainable source for irrigation of energy crops. Vegetation filter systems are considered a reliable technique for sustainable biomass cultivation, enabling the use of reclaimed wastewater as water and nutrients sources during irri...
Acquiring multi-temporal spatial information on vegetation condition at scales appropriate for site-specific agricultural management is often complicated by the need for meticulous field measurements. Understanding spatial/temporal crop cover heterogeneity within irrigated croplands may support sustainable land use, specifically in areas affected by land degradation due to secondary soil salini...
This paper focuses attention on the relevance of the notion of sustainable development in a regional context and the use of models in analyzing sustainable development. The paper discusses first the notion of sustainable development, linking socio-economic, ecological and political-ethical elements. Time and space prove to be important dimensions of sustainable development, in both distribution...
This paper describes a wireless sensor network that monitored water extraction rate, salinity and water table level. The network collected real-time water quality measurements in order to investigate the impacts of current irrigation practice on the environment, in particular underground water salination. Particular challenges included a large coverage area, a sparse network with mean link dist...
Introduction Three quarters of the farmers in developing countries cultivate less than five acres. The productivity of these small farmers is the key to practical sustainable solutions to the growing problem of food security in the world. In light of this, it is remarkable that the critical needs of microfarmers have for so long been ignored, both by both the development establishment influence...
Modelling crop evapotranspiration (ET) response to different planting scenarios in an irrigation district plays a significant role in optimizing crop planting patterns, resolving agricultural water scarcity and facilitating the sustainable use of water resources. In this study, the SWAT model was improved by transforming the evapotranspiration module. Then, the improved model was applied in Qin...
Safeguarding river ecosystems is a precondition for attaining the UN Sustainable Development Goals (SDGs) related to water and the environment, while rigid implementation of such policies may hamper achievement of food security. River ecosystems provide life-supporting functions that depend on maintaining environmental flow requirements (EFRs). Here we establish gridded process-based estimates ...
