Can short-term conditional subsidies sustain agroecology adoption? Evidence from Zimbabwe by Ngoma, Hambulo, Gebremariam, Gebrelibanos, Zingwena, Taurai, Thierfelder, Christian, Chimonyo, Vimbayi Grace Petrova

“…We assess the extent to which the Zimbabwean government’s large-scale conditional ISP, Pfumvudza, can sustain agroecology adoption using framed economic field experiments. We found indicative evidence suggesting that the provision of conditional subsidies for two consecutive seasons increased adoption by 5% and sustained it even after the subsidy was withdrawn. …”

Fragility of the provision of local public goods to private and collective risks by Cárdenas, J.C., Janssen, Marco A., Ale, M., Bastakoti, Ram C., Bernal, A., Chalermphol, J., Gong, Y., Shin, H., Shivakoti, G.P., Wang, Y., Anderies, J.M.

“…These communities are being increasingly integrated into the global economy and are exposed to new global climate-related risks that may affect their willingness to cooperate in community-level collective action problems. We performed field experiments on public goods with private and collective risks in 118 small-scale rice-producing communities in four countries. …”

Development of hand tractor-mounted seed drill for rice-based cropping systems in the Philippines by Bautista, Elmer G., Gagelonia, Eden C., Abon, John E., Corales, Aurora M., Bueno, Crisanta S., Banayo, Niño P.M.C., Lugto, Roman V., Suralta, Roel R., Kato, Yoichiro

“…The results suggested that the prototype with tined furrow openers and an inclined circular seed plate in the hopper for seed metering driven by the ground wheel through the combination of chain and sprocket produced rice grain yield similar to the crop established from broadcasting. Field experiments also confirmed that the seed drill has a capacity of over 2 ha day−1 for rice and over 3 ha day−1 for mung bean, and thus, the prototype appears promising for rainfed lowlands in the Philippines.…”
