Lagged precipitation effect explains a large proportion of annual aboveground net primary productivity in some dryland ecosystems. Using satellite-derived plant productivity and precipitation datasets in the Northern Hemisphere drylands during 2000-2018, we identify 1111 pixels mainly located in the Tibetan Plateau, the western US, and Kazakhstan w...
Arid areas in East Africa are characterized by physical water scarcity. The physical water scarcity is further exacerbated by poor water quality (mainly salinity and fluoride) of mainly groundwater sources. Combined physical water scarcity and poor water quality makes the region a hydrogeologically difficult environment. Nevertheless, some viable h...
ABSTRACT. Agricultural production in semi-arid regions is limited due to water availability. In addition, the water quality available for irrigation is often compromised due to the high salt content present. Millet is a forage species considered tolerant to water deficit and moderately salt tolerant. In view of the above, the objective was to evalu...
Groundwater, the largest available global freshwater resource, plays a crucial role in human sustenance and global food security through drinking water supplies and irrigated agriculture. In recent times, many parts of the world have been experiencing discernable, large-scale groundwater depletion, and pollution. A large groundwater-dependent popul...
This report explores how women perceive participation and empowerment vis-a-vis access to water and other agricultural resources in the Tarai/Madhesh of Nepal. The report argues that gendered vulnerability is indeed intricately connected with other axes of difference, such as caste and economic status, despite women’s critical role in agricultural ...
The African Water Facility, together with the Water Research Commission, South Africa, as its implementing agent, supported the demonstration project Operationalizing community-led Multiple Use water Services (MUS) in South Africa. As knowledge broker and research partner in this project, the International Water Management Institute (IWMI) analyzed...

Extreme events such as extreme drought and precipitation are expected to increase in intensity and/or duration in the face of climate change. Such changes significantly affect plant productivity and the biomass allocation between reproductive and vegetation organs (i.e., reproductive allocation). Our aims are to test the effects of water addition o...

AbstractReference evapotranspiration (ET0) plays a key role in irrigation system design as well as water management of agricultural ecosystems under irrigated and rainfed conditions. While many methods for estimating the ET0 have been developed during the past several decades, method selection essentially depends on the availability of measured cli...
Silicij (Si) je za rastline zelo koristen element, saj pripomore k izboljšanju njihovega uspevanja v različnih stresnih razmerah, med drugim tudi v primeru vse pogostejšega pomanjkanja vode in povečanega UV sevanja. Naravno UV sevanje je ključno za normalen razvoj rastlin, hkrati pa lahko poveča tudi njihovo odpornost proti suši. Proučili smo vpliv...
