Heterogeneous multidimensional efficiency effects of agro-ecological pest management transition and intensification in smallholder systems–evidence from mango fruit fly control in... por Owili, S.O., Otieno, D.J., Chimoita, E.L., Baijukya, F.P.

“…Agro-ecological transition is an important step towards sustainable and resilient food systems in the face of systemic threats from climate-change-induced disturbances. In smallholder systems, the transition towards agro-ecological pest management (APM) offers the prospect of reconciling agronomic performance with environmental and social imperatives by replacing indiscriminate chemical applications with locally-derived biorational options. …”

Agroecological impacts of crop residue burning: a qualitative systematic review of direct and inferred evidence por Parambil-Peedika, Ashiq, Laing, Alison M., Gathala, Mahesh Kumar, Adeeth AG Cariappa, Krishna, Vijesh V.

“…Findings from broader air pollution studies, used here as secondary evidence, offer valuable inferential insights into the potential ecological impacts of crop residue burning on birds and arthropods, mediated through changes in air quality. Despite these documented consequences, agrobiodiversity considerations are largely absent from policy discussions on residue management. …”

Heterogeneous demand for agricultural lime in Tanzania: Recent empirical evidence and implications for policy por Gebrekidan, Bisrat, Jaleta, Moti, Chamberlin, Jordan, Kuboja, Nicholaus M.

“…As countries with acidity constraints evaluate their policy options– which may include targeted extension, investments in lime production and market development, or inclusion of lime in input subsidy schemes– they are constrained by limited evidence on how farmers value lime, what drives their demand, and how demand would respond to pricing changes in local markets. To address this gap in one country with significant soil acidity constraints, Tanzania, we estimate the willingness of smallholder farmers to pay for lime using a double bounded dichotomous choice contingent valuation method. …”

Fostering learning among the next generation of veterinarians: incorporating one health and antimicrobial stewardship into veterinary medicine training curricula in Ethiopia por Nyokabi, N., Phelan, L., Berg, S., Lindahl, Johanna F., Korir, L., Bett, Bernard K., Muunda, Emmanuel, Mihret, A., Moore, H., Wood, J.

“…Universities play a crucial role in educating and training veterinarians, and their fostering of learning among the next generation of students is widely regarded as key to bringing about the cultural change required to realise a transition towards a ‘One Health’ approach to managing human, animal, and environmental health and underpin widespread adoption of antimicrobial stewardship practices. …”

Engaging traders in strengthening seed systems in Tanzania: key drivers for selling grains of improved varieties of sorghum, common beans and groundnuts por Ong’or, Dennis, Ochieng, Justus, Mwakatwila, Atupokile, Mutua, Mercy, Radegunda, Kessy, Kelemera, Sylvia, Aseete, Paul, Mwenda, Emmanuel, Kadege, Edith, Madeni, Joachim, Rubyogo, Jean Claude

“…Therefore, to spur the uptake of improved varieties, strengthening trader-farmer linkages, integrating traders into structured procurement systems, and enhancing trader involvement in participatory variety selection to refine existing and preferred varieties without changing them altogether are recommended. Additionally, there is need to strengthen business modeling programs to make grain traders’ businesses bankable, expand information sharing and facilitate access to credit enabling them to adequately offer technical support to the farmers they source grains from.…”

The effects of supplementation with Gliricidia sepium or Leucaena leucocephala forage on intake, digestion and live-weight gains of Bos taurus X Bos indicus steers offered Napier g... por Abdulrazak, S.A., Muinga, R.W., Thorpe, W.R., Orskov, E.R.

“…Two experiments were carried out to evaluate the effect of incremental levels of Gliricidia sepium (gliricidia) and Leucaena leucocephala (leucaena) on forage intake, diet apparent digestibility, microbial nitrogen supply and live-weight changes in cattle. In each experiment, 20 intact and five fistulated crossbred steers (Bos taurus X Bos indicus) were used. …”

“…Integrating improved grass and legume forages into mixed production systems (crop–livestock, tree–livestock, crop–tree–livestock) can restore degraded lands and enhance system resilience to drought and waterlogging associated with climate change. When properly managed tropical forages accumulate large amounts of carbon in soil, fix atmospheric nitrogen (legumes), inhibit nitrification in soil and reduce nitrous oxide emissions (grasses), and reduce GHG emissions per unit livestock product. …”
