Agricultural mechanization and gendered labor activities across sectors: Micro-evidence from multi-country farm household data por Takeshima, Hiroyuki, Diao, Xinshen

“…This study aims to partly fill these knowledge gaps through micro-evidence from 8 countries (Ethiopia, Ghana, Nigeria, Tanzania, India, Nepal, Tajikistan and Vietnam), using several nationally representative panel data and supplementary data, and applying Correlated-Random-Effects Double-Hurdle models with Instrumental-Variables. We find that the use of tractors and/or combine harvesters by the household induces greater shift from farm activities to non-farm activities by female members than by male members. …”

Lessons Learned from Implementing the CAADP Biennial Review Process Under the Malabo Declaration por Makombe, T., Ulimwengu, John M., Matchaya, Greenwell C.

“…While the BR has prompted policy and programmatic changes in several countries, its full impact is hindered by persistent challenges such as underfunding, weak monitoring and evaluation (M&E) capacities, and data quality issues. Despite these hurdles, innovations like the eBR and national data clusters have led to improvements in data quality and reporting rates. …”

A Review of Global Policy Mechanisms Designed for Tropical Forests Conservation and Climate Risks Management por Muthee, K., Duguma, L., Wainaina, P., Minang, Peter A., Nzyoka, J.

“…The study establishes that the mechanisms in place have contributed mainly to more coordination and incentives to manage climate risks, primarily through tropical forests conservation. However, hurdles such as inadequate participation and involvement of the local and indigenous people, insufficient national and local policy frameworks and bureaucracies around emissions monitoring, measuring, reporting, and verification processes continue to slow tropical forest conservation. …”

Apical Rooted Cuttings Revolutionize Seed Potato Production by Smallholder Farmers in the Tropics por VanderZaag, P., Pham, T.X., Demonteverde, V.E., Kiswa, C., Parker, M., Nyawade, S., Wauters, P., Barekye, A.

“…The demystification of tissue culture by the 1980s greatly aided this development. The key hurdle was to multiply tissue culture plants in beds of growing media and maintain the physiological young stage of the mother plants from which apical cuttings could be repeatedly taken for several months to produce ARC for sale to farmers who demanded the new cultivars (cvs) with all the desirable attributes. …”
