Unlocking value out of India's rainfed farming areas. por Sharma, Bharat R.

“…Low and uncertain crop yields and concentrated poverty in the vast rainfed regions, diminishing returns from the public irrigation systems, climate change induced chaotic fluctuations in the hydrologic regimes and a large demand-supply gap in non-cereal food items are all compelling reasons for the need to realise the production potential of rainfed farming areas. …”

Overcoming growing water scarcity: exploring potential improvements in water productivity in India por Amarasinghe, Upali A., Malik, Ravinder Paul Singh, Sharma, Bharat R.

“…The paper first finds the maximum yield function conditional on consumptive water use (CWU) and then explores the potential improvements in WP by: (a) bridging the gap between actual and maximum yield while keeping CWU constant; and (b) changing the maximum yield by adjusting the CWU using supplementary or deficit irrigation. …”

Intake, digestion, and nitrogen utilization by sheep fed tropical legumes with contrasting tannin concentration and astringency por Barahona Rosales, Rolando, Lascano Aguilar, Carlos Eduardo, Cochran, R, Morrill, J, Titgemeyer, EC

“…Extraction of CT with PEG resulted in less (P < .05) ruminal escape protein and less (P < .01) fecal N with both legumes, but apparent postruminal N digestion was not affected. Changes in the concentration of extractable CT in tropical legumes can significantly affect forage intake, digestion, and N utilization by sheep.…”

Sustainable intensification?: Implications for the emergence of diseases por Grace, Delia, Bett, Bernard K., Unger, Fred, Hung Nguyen-Viet

“…A systematic literature review was conducted to synthesize best available scientific knowledge about zoonotic disease transmission through direct or indirect domestic livestock-wildlife interaction, with emphasis on risk factors, drivers and trajectories of transmission, and promising interventions for controlling important zoonoses based on managing livestock-wildlife interaction.The study found complex associations with agricultural intensification and disease emergence: • Biodiversity, bush meat consumption, expanding ecotones, increases in synanthropoic species, land use change and livestock intensification are commonly cited and inter-related causes of emerging infectious diseases…”
