In central and southern Malawi, climate variability significantly impacts agricultural production food availability owing to a high dependence on rain-fed maize production. Seasonal forecast information has the potential inform farmers' planning, thereby improving preparedness extreme events. this paper we describe evaluate an approach co-designing testing agro-climatic indices for use in seaso...

Annual growth of semiarid tree species is generally limited by a period of water deficit and this relationship can be reflected in interannual variation in tree-ring width of semiarid species such as Pinus edulis, a piñon pine that is widely distributed across the southwestern United States. Tree-ring width of P. edulis and other semiarid tree species is most frequently related to annual precip...

The National Agricultural Decision Support System (NADSS) is a web based geospatial decision support system used to aid producers and decision makers in analyzing and effectively mitigating the effects of drought. The NADSS application is unique in its implementation, containing web-based implementations of commonly utilized drought indices including the Newhall Simulation Model (NSM), Palmer D...

The sensitivity of agricultural productivity to climate has not been sufficiently quantified. The total factor productivity (TFP) of the US agricultural economy has grown continuously for over half a century, with most of the growth typically attributed to technical change. Many studies have examined the effects of local climate on partial productivity measures such as crop yields and economic ...

Abstract Large-scale interdependent teleconnections influence precipitation at various spatio-temporal scales. Selecting the relevant climate indices based on geographical location is important. Therefore, this study focuses spatial multivariate selection of influencing variability over India, using partial least square regression and variable importance projection technique. 17 gridded dataset...
