Beyond agriculture versus non-agriculture: Decomposing sectoral growth–poverty linkages in five African countries por Dorosh, Paul A., Thurlow, James

“…We find that the poverty–growth elasticities for trade and transport services and manufacturing, especially agro-processing, are often close to, and sometimes exceed, agriculture’s. This means that growth led by these nonagricultural subsectors might be as effective as agriculture at reaching the poor. …”

The application of social cost-benefit analysis to the evaluation of PROGRESA: final report por Coady, David

“…When monetary values can be attached to these impacts they are referred to as “program benefits” and the application of cost-benefit analysis (CBA) then involves determining whether benefits exceed costs and by how much. In the absence of a monetary valuation of impacts, one is restricted to the use of cost-effectiveness analysis (CEA), which identifies the cost of bringing about a given impact.…”

Root-Induced Iron Oxidation, pH Changes and Zinc Solubilization in the Rhizosphere of Lowland Rice por Kirk, G.J.D., BAJITA, J.B.

“…The zones of accumulation and depletion coincided with zones of Fe(III) accumulation and soil acidification in which the pH decreased from the bulk soil value of 7.3 by over 0.2 pH units; i.e. a two‐fold increase in H+ concentration, The acidification was the result of H+ released from the roots to balance excess intake of cations over anions, and H+ generated in the oxidation of Fe(H) by root‐released O2. …”

Spraying high concentrations of chelated zinc enhances zinc biofortification in wheat grain por Xu, Meng, Liu, Mengjiao, Si, Linlin, Ma, Qingxu, Sun, Tao, Wang, Jun, Chen, Kaijun, Wang, Xiangjie, Wu, Lianghuan

“…BACKGROUND Foliar application of highly concentrated ZnSO4 fertilizer improves Zn biofortification in wheat grains. However, excess ZnSO4·7H2O concentration (≥5 g kg−1, w v−1) has been associated with leaf burn and yield loss, necessitating Zn sources with a high threshold concentration. …”

Regeneration, growth and sustainability of mahogany in Mexico's Yucatan forests por Snook, Laura K.

“…Assuming constant growth, a big-leaf mahogany requires 122 years, on average, to reach the 55-cm minimum cutting diameter, although the fastest-growing trees may do so in 82 years. the current selective harvesting system, based on a 25-year cutting cycle, cannot be expected to ensure sustainable harvests of big-leaf mahogany because extraction exceeds growth and adequate regeneration conditions are not provided. …”
