Agricultural R&D investments and policy development goals in Sub-Saharan Africa: Assessing prioritization of value chains in Senegal por Benfica, Rui

“…Considering that growth in VCs affects those various outcomes differently, as expansion pathways result in the diverse use of production factors and inputs, trade-offs from linkages across sectors, and changes throughout the agri-food system, this analysis uses (i) the RIAPA dynamic computable general equilibrium model to identify which agricultural VCs, when expanded through TFP growth, provide the strongest effects on the development outcomes of interest; (ii) the perpetual inventory model (PIM) to represent the lagged effect of research through knowledge stocks of agricultural R&D investments; and (iii) information on the elasticities of VC agricultural activity TFP with respect to agricultural R&D knowledge stocks, to discuss the VC priority allocations of R&D resources in Senegal. …”

The paradox of limited maize stover use in india's smallholder crop-livestock systems por Erenstein, Olaf, Samaddar, Arindam, Teufel, Nils, Blümmel, Michael

“…Cereal residues are an important feed source for ruminants in smallholder crop-livestock systems in the (sub)tropics. In many areas of India maize is a relatively new cash crop where farmers and development agents alike generally perceive maize stover to have limited utility, in contrast with the intensive feeding of other cereal residues in India and the intensive use of maize stover in sub-Saharan Africa and Latin America. …”

Site-specific nutrient management advice and agricultural intensification in maize-based systems in Nigeria por Oyinbo, O.

“…Relaxing such constraints via agricultural extension interventions is expected to produce positive outcomes but do not always result in the intended effects, which may be connected with the highly heterogeneous smallholder farming systems. Yet, traditional extension systems in SSA countries, including Nigeria, provide general fertilizer use recommendations, which do not account for the substantial variation in production conditions. …”

Inventory of diseases on dipterocarps in natural forest with different cutting intensities and on mixed species in a taungya system plantation por Mardji, D.

“…Sound trees should be preferred to diseased trees for seed trees. In the taungya plantation there were generally more sound plants of all species compared to diseased and dead ones, except for Manihot esculenta and Glycine max which were more diseased than sound. …”

Cultural and economic barriers and opportunities for the participation of women in agricultural production systems: A case study in Guatemala por Hernandez, Manuel A., Alarcón, Constanza, Berrospi, Maria Lucia, Lopera, Diana Carolina, Quintero, Diana, Reyes, Byron A., Olivet, Francisco

“…The study provides several interesting findings, which generally hold across locations. First, women do not seem to have a strong preference for crop production activities, except harvesting, and only get involved in specifically assigned tasks. …”

Reimagining cost recovery in Pakistan’s irrigation system through willingness-to-pay estimates for irrigation water from a discrete choice experiment por Bell, A.R., Ali Shah, Azeem M., Ward, Patrick S.

“…It is widely argued that farmers are unwilling to pay adequate fees for surface water irrigation to recover the costs associated with maintenance and improvement of delivery systems. In this paper, we use a discrete choice experiment to study farmer preferences for irrigation characteristics along two branch canals in Punjab Province in eastern Pakistan. …”

Multi-stakeholder perception analysis of the status, characteristics, and factors affecting small-scale carp aquaculture systems in Bangladesh por Rossignoli, Cristiano, Lozano, Denise, Barman, Benoy, Brako Dompreh, Eric, Manyise, Timothy, Wang, Quanli, Dam Lam, Rodolfo, Moruzzo, Roberta, Paz Mendez, Alvaro, Gasparatos, Alexandros

“…Very diverse actions from national governments, civil sector and international organizations have been seeking to enhance the performance of small-scale aquaculture systems. However, many of these efforts are constrained by the general lack of information about the status and characteristics of the sector. …”

Experimental field exclosure of birds and bats in agricultural systems — Methodological insights, potential improvements, and cost-benefit trade-offs por Maas, Bea, Heath, Sacha, Grass, Ingo, Cassano, Camila, Classen, Alice, Faria, Deborah, Gras, Pierre, Williams Guillén, Kimberly, Johnson, Matthew, Karp, Daniel S., Linden, Valerie, Martínez Salinas, Alejandra, Schmack, Julia M., Kross, Sara

“…We then analyzed the potential of exclosure methods and possible extensions to improve our understanding of complex food webs and ecosystem services affecting the productivity of agricultural systems. While preferences exist in materials (e.g., nylon nets and bamboo frames), experimental exclosure studies of birds and bats differed greatly in their respective design, related costs, and effort — limiting the generalization and transferability of results at larger spatial scales. …”
