An inclusive rural transformation in progress, but with unequal pace and characteristics across countries por Benfica, Rui

“…Finally, with respect to the inclusive nature of the transformation process, this paper undertook an empirical analysis relying on simple correlations, and found that: (a) over time and for all poverty, inequality and shared prosperity measures, the process of rural transformation through increased agricultural labour productivity, results in statistically significant improvements in the region; (b) the strength of the association of rural transformation with the inclusion process was higher in the period 2007-2012, particularly with respect to extreme poverty. …”

Effects of free-air CO2 enrichment (FACE) and soil warming on CH4 emission from a rice paddy field: impact assessment and stoichiometric evaluation por Tokida, T., Fumoto, T., Cheng, W., Matsunami, T., Adachi, M., Katayanagi, N., Matsushima, M., Okawara, Y., Nakamura, H., Okada, M., Sameshima, R., Hasegawa, T.

“…The enhancement in CH4 emission from the FACE-effect alone (+ 26%) was statistically non-significant (P = 0.19). Nevertheless, observed positive correlations between CH4 emissions and rice biomass agreed well with previous studies, suggesting that higher photosynthesis led to greater rhizodeposition, which then acted as substrates for methanogenesis. …”
