Agriculture-driven deforestation in the tropics from 1990-2015: emissions, trends and uncertainties por Carter, S., Herold, Martin, Avitabile, Valerio, Bruin, S. de, Sy, Veronique de, Kooistra, L., Rufino, Mariana C.

“…Latin America had the highest emissions from agriculture-driven deforestation, and these peaked at 974 ± 148 Mt CO2 yr−1 in 2000–2005. Africa saw a continuous increase in emissions between 1990 and 2015 (from 154 ± 21–412 ± 75 Mt CO2 yr−1), so mitigation initiatives could be prioritized there. …”

Contribution of dry forest products to household income and determinants of forest income levels in the northwestern and southern lowlands of Ethiopia por Teshome, B., Kassa, H., Mohammed, Z., Padoch, Christine

“…Forest income level was significantly and positively influenced by family size (P < 0.01) and being a member of gums and resins producers cooperative (P < 0.01), while distance to the forest resource (P < 0.01) and being in Tigray or Amhara Regional States (Oromia being reference state) negatively and significantly affected forest income levels of households. …”

Response of yam (Dioscorea rotundata Poir.) to various periods of weed interference in an intercropping with maize (Zea mays L.), okra (Abelmoschus esculentus L. Moench), and sweet... por Orkwor, G., Okereke, O., Ezedinma, C.I., Hahn, S., Ezumah, H., Akobundu, I.

“…The field trials were conducted for two cropping seasons at the research farm of the National Root Crops Institute, Umudike, Nigeria, 5° 29' N latitude and 7° 32' E on an altitude of 122 m above sea level to determine the critical period of weed interference in yam/maize/okra/sweet potato intercrop; assess the crop yield losses due to uncontrolled associated weeds; and assess the wrong timing of the removal of weeds and the ability of sweet potato to suppress weeds as a planofile in the mixture. The critical period of weed interference in the intercrop was between 3 and 16 weeks after planting (WAP). …”

Nutritionally versatile, abiotic stress resistant and symbiotically effective chickpea (Cicer arietinum L.) root nodulating rhizobial isolates from eastern, southeastern and southe... por Gebremedhin, W., Assefa, F., Thuita, Moses N., Masso, C.

“…However, chickpea production is very low due to poor soil fertility, poor nodulation and lack of inoculation with effective rhizobia. In this study a total of 39 root nodule bacteria were collected from nodules of 60 sampling sites from chickpea growing areas of the eastern, southeastern and southern parts of the country, of which 23 isolates (59%) were identified as chickpea root nodule bacteria based upon presumptive and definitive (authentication) tests. …”

Biological effects of plant residues with contrasting chemical composition under humid tropical conditions decomposition and nutrient release por Tian, G., Kang, B., Brussaard, Lijbert

“…Negative correlations were observed between decomposition rate constants and C:N ratio (P < 0.004), percent lignin (P < 0.014) and polyphenol content (P < 0.053) of plant residues. A positive correlation was observed between decomposition rate constant and mesh-size of litterbag (P < 0.057). …”
