Ecoinformatics for integrated pest management: expanding the applied insect ecologist's tool-kit por Rosenheim, Jay A., Parsa, S, Forbes, AA, Krimmel, WA, Law, YH, Segoli, M, Sivakoff, Frances S., Zaviezo, T, Gross, K

“…A survey of the literature suggests that many contemporary yield-impact studies lack sufficient statistical power to resolve the small, but economically important, effects on crop yield that shape pest management decision-making by farmers. Ecoinformatics-based data sets can be substantially larger than experimental data sets and therefore hold out the promise of enhanced power. …”

Integrating research on food and the environment: An exit strategy from the rational fool syndrome in agricultural science por Ashby, Jacqueline A.

“…As a result, mainstream agricultural science has ignored negative impacts or externalities, which has contributed to a crisis of credibility with the general public and politically sensitive decision makers. A long-term strategic research agenda for the public sector is being defined that is new and relevant to present efforts to integrate natural resource management and sustainable agricultural production. …”

Managing the health risks associated with agriculture: An overview of research by the International Livestock Research Institute por Lore, Tezira A., Grace, Delia

“…Key areas of focus of this theme are: ● food safety: participatory risk assessment in milk and meat value chains in informal markets as well as risk and economic assessment of aflatoxins ● neglected zoonoses: epidemiology, ecology and socio-economics of disease emergence in urban areas ● emerging infectious diseases: mapping the risk of vector-borne diseases; determining the drivers of disease emergence and transmission; and modelling of disease transmission to improve decision-making towards preventing and controlling diseases The research outputs will be used by value chain actors, policymakers, development program implementers and governments to improve animal-source food value chains and prevent and control infectious diseases. …”

Modifying DSSAT crop models for low-input agricultural systems using a soil organic matter-residue module from Century por Gijsman, A.J., Hoogenboom, Gerrit, Parton, WJ, Kerridge, Peter C.

“…In low-input systems, where most nutrients become available from soil organic matter (SOM) and residue turnover, the applicability of DSSAT (Decision Support System for Agrotechnology Transfer) crop simulation models is limited because (i) it recognizes only one type of SOM (i.e., humus) and recently added, but not yet humified, residue; (ii) it does not recognize a residue layer on top of the soil; (iii) newly formed humus is given a fixed C/N ratio of 10; (iv) only one litter pool is recognized for N although three are recognized for C; (v) for residues with C/N ratios <25, the three litter pools for C decompose at a rate that is independent of the residue's N concentration; and (vi) SOM and residue flows are independent of soil texture. …”

Farmers' perceptions of East Coast fever risk and adoption of control strategies in Kenya por Leneman, J.M., McDermott, John J., Okuthe, O.S., Randolph, Thomas F.

“…In Kenya, some smallholder dairy farmers apply one or more of these control strategies; however, a large number of them do not actively control the disease and accept its risks and production limitations. These decisions are influenced by farmers perceptions of both ECF risk on production and the biological and economic risks of available ECF control options. …”

Cost-effective methods for accurate determination of sea level rise vulnerability: a Solomon Islands example por Albert, S., Abernethy, K.A., Gibbes B, Grinham A, Tooler N, Aswani S

“…For areas where lidar is not economically viable, this method is intended to provide an important balance of cost, simplicity, accuracy, and local participation that can assist remote coastal communities with coastal planning decisions. The method can enhance local capacity and arguably promotes more meaningful local engagement in sea level rise planning and adaptation activities.…”
