Soil carbon and nitrogen emissions under farmer managed conservation agriculture in Zimbabwe por Meyer zu Drewer, Johannes, Thierfelder, Christian, Buerkert, Andreas

“…The GHG emissions from a total of 8 farms depended on soil temperature and moisture and tended to be higher in CONV fields, although differences were statistically not significant. Field emissions were highest under warm-moist conditions, which are prevailing for large parts of the growing season. …”

Fostering Kalanamak rice farmer’s resilience and profitability in India by integrating local knowledge into the seed system and markets por Nayak, Swati, Nath, Anirban, Shukla, Sarvesh, Hossain, S.K. Mosharaf, Badoni, Saurabh, Singh, Vivek Kumar

“…Results Semi-dwarf cultivars such as Bauna Kalanamak 101, Bauna Kalanamak 102, and Kalanamak Kiran showed higher mean yield compared to the traditional accessions; however, the differences in yield were statistically non-significant. Findings revealed a hybrid seed network where decentralized farmer-to-farmer exchange coexists with collective-led procurement and emerging private sector channels. …”

Estimation of groundwater recharge and potentials under changing climate in Werii Watershed, Tekeze River Basin por Gebremeskel, G.

“…This study was conducted in Werii watershed (1797 km2) of Tekeze river basin, through integrative use of hydrological and climate models with the objective of estimating the impact of climate change on groundwater recharge and groundwater potentials. Statistical downscaling model (SDSM) was used to downscale precipitation and temperature outputs from REMO (REgional climate MOdel) which in turn was used as input to the WetSpa model to simulate future water balance changes based on A1B and B1 SRES emission scenarios. …”

An integrated study of human and animal infectious disease in the Lake Victoria crescent small-holder crop-livestock production system, Kenya por Fèvre, Eric M., Glanville, William A. de, Thomas, Lian F., Cook, Elizabeth A.J., Kariuki, S., Wamae, C.N.

“…Evidence for spatial clustering in exposure or infection was identified using the spatial scan statistic. Results There was a high prevalence of human parasitism in the community, particularly with hookworm (Ancylostoma duodenale or Necator americanus) (36.3% (95% CI 32.8–39.9)), Entamoeba histolytica/dispar (30.1% (95% CI 27.5–32.8)), and Plasmodium falciparum (29.4% (95% CI 26.8–32.0)). …”
