Hydro-economic model framework for achieving groundwater, food, and economy trade-offs by optimizing crop patterns.

When allocating water resources, stakeholders (such as water departments, agricultural sector actors, and farmers) aim to maximize their benefits. This leads to conflicts between water savings, food security, and profit growth, causing major challenges for water managers. A hydro-economic model was developed to alleviate groundwater sustainability, food security, and economic growth (GFE) conflicts through crop pattern optimization.

Seroprevalence and predisposing factors of rabies antibodies in unvaccinated dogs in Sierra Leone.

Objective: This study determines the seroprevalence and associated factors of rabies in unvaccinated dogs in Sierra Leone.

Background: Rabies control is poorly coordinated in Sierra Leone which was ranked as the third hungriest country in the world. Due to limited access to rabies vaccines, the need for comprehensive serological data on dogs for control of the disease is expedient.

Attribution of hydrological change in Heihe River Basin to climate and land use change in the past three decades.

The contributions of climate and land use change (LUCC) to hydrological change in Heihe River Basin (HRB), Northwest China were quantified using detailed climatic, land use and hydrological data, along with the process-based SWAT (Soil and Water Assessment Tool) hydrological model. The results showed that for the 1980s, the changes in the basin hydrological change were due more to LUCC (74.5%) than to climate change (21.

GRACE, GLDAS and measured groundwater data products show water storage loss in Western Jilin, China.

Water storage depletion is a worsening hydrological problem that limits agricultural production in especially arid/semi-arid regions across the globe. Quantifying water storage dynamics is critical for developing water resources management strategies that are sustainable and protective of the environment. This study uses GRACE (Gravity Recovery and Climate Experiment), GLDAS (Global Land Data Assimilation System) and measured groundwater data products to quantify water storage in Western Jilin (a proxy for semi-arid wetland ecosystems) for the period from January 2002 to December 2009.
