Decisions about reducing agricultural land tillage to offset global warming potential (GWP) are based on the evaluation of the agricultural eco-system and the profitability to local farms. Carbon sequestration and nitrous oxide emissions from winter wheat (WW) cropping were evaluated by modeling typical dryland cropping systems in eastern Washington. Variations in rainfall, tillage intensity an...

Unfavorable weather currently ranks among the major challenges facing agricultural development in many African countries. Impact mitigation through access to reliable and timely weather forecasts and other adaptive mechanisms are foremost in Africa’s policy dialogues and socio-economic development agendas. This paper analyzed the factors influencing access to forecasts on incidence of pests/dis...

In 2003, a network for hydrology of the semiarid region (REHISA in Portuguese) was created in Brazil. Since then, experimental watersheds in this region has been providing hydrometeorological data collected in automatic stations. However, the spatial distribution of these gauges might be insufficient to thoroughly understand the hydrological processes occurring in the area. Remotely sensed hydr...

Saba senegalensis is a multi-purpose liana from sub-Saharan Africa that under threat over-exploitation of its fruits and land degradation erratic rainfall affecting regeneration. This research aims to assess survival, growth dry matter distribution in the responses water regimes S. seedlings nine provenances slightly, moderately severely zones Burkina Faso.

The Weihe Basin is a crucial part of the Fenwei Graben System and typical example an extensional fault basin. Over time, region has been developed around 212 ground fissures, with majority them being associated heavy rainfall. These water-eroded fissures have caused serious damage to farmland, houses, roads, Liangjiacun Meiyuancun Dizhentai most known. To understand developmental characteristic...

The effects of biotic and abiotic factors on stem borer parasitoid diversity, abundance, and parasitism were studied in cultivated and natural habitats in four agroecological zones in Kenya. Comparing habitat types, we found partial support for the "natural enemy" hypothesis, whereby, across all localities, parasitoid diversity was higher in more diverse host plant communities in natural habita...

we estimated the rainfall interception loss (i), canopy storage capacity (s), the ratio of mean evaporation rate from the wet canopy () over the mean rainfall intensity () (mm h-1) (), and free throughfall coefficient (p) in a fraxinus rotundifolia mill. stand located in an afforested park land in a semiarid region of iran. for each storm event, i was calculated as the gross rainfall (gr) minus...

Spatio-temporal modelling is an area of increasing importance in which models and methods have often been developed to deal with specific applications. In this study, a spatio-temporal model was used to estimate daily rainfall data. Rainfall records from several weather stations, obtained from the Agritempo system for two climatic homogeneous zones, were used. Rainfall values obtained for two f...

Groundwater management practices need to take hydrogeology, the agro-climate and demand for groundwater into account. Since agroclimatic zones have already been demarcated by the Government of India, it would aid policy makers to understand the status of groundwater recharge and discharge in each agroclimatic zone. However, developing effective policies to manage groundwater at agroclimatic zon...
