Eucalyptus plantations occupy almost 20 million ha worldwide and exceed 3.7 million ha in Brazil alone. Improved genetics and silviculture have led to as much as a three-fold increase in productivity in Eucalyptus plantations in Brazil and the large land area occupied by these highly productive ecosystems raises concern over their effect on local water supplies. As part of the Brazil Potential ...

In this study, we aimed to improve rice farmers’ productivity and profitability in rainfed lowlands through appropriate crop nutrient management by closing the yield gap during dry season of Indonesia. The Integrated Crop Management package, involving recommended practices (RP) from Indonesian Agency for Agricultural Research Development (IAARD), were compared current at ten farmer-participator...

Climate variability can induce uncertainty in yields, and threaten long term economic viability of rainfed agricultural enterprises in the absence of effective adaptation strategies. Enterprise mix diversification has been found to be an effective adaptation strategy for mitigating multiple sources of farm business risk in some contexts. The extent to which enterprise mix diversification can mi...

Rainfed agriculture is one of the most common farming practices in world and vulnerable to global climate change. However, only limited studies have been conducted on rainfed agriculture, mainly using low-frequency manual techniques, which caused large uncertainties estimating annual N 2 O emissions. In this study, we used a fully automated system continuously measure soil emissions for two yea...

BACKGROUND In this work, we aimed to gain insights into the contribution of soil bacteria to carbon sequestration in Mediterranean habitats. In particular, we aimed to use bacterial laccase-encoding genes as molecular markers for soil organic C cycling. Using rainfed olive farming as an experimental model, we determined the stability and accumulation levels of humic substances and applied these...

Relative (actual / potential) evapotranspiration (RET) was derived using ten-day composite NOAA PAL datasets (8km x 8km spatial resolution) over Indian landmass and an operational energy balance algorithm for five agricultural years (June-May) between 1996 to 2001. This was used to characterize ‘Kharif’ (June-October) rice growing environment and its yield prediction in rainfed conditions. Inve...

This study assesses the vulnerability of Bulgarian agriculture to drought using the WINISAREG model and seasonal standard precipitation index SPI(2) for the period 1951-2004. This model was previously validated for maize on soils of different water holding capacity (TAW) in various locations. Simulations are performed for Plovdiv, Stara Zagora and Sofia. Results relative to Plovdiv show that in...
