Environmental services and the precautionary principle: using scenarios to reconcile conservation and livelihood objectives in upper catchments por German, L., Villamor, Grace B., Twine, Edgar E., Velarde, S.J., Kidane, B.

“…This article analyzes ethnobotanical data from three sites in the eastern African highlands to analyze the likely consequences of applying diverse regulatory and incentive (ESR) schemes. Data illustrate that when applied in isolation, carbon rewards can undermine water conservation and local livelihood objectives alike through expansion of fast-growing tree species at the expense of water supply and other land uses. …”

Fences in our heads: a discourse analysis of the korup resettlement stalemate por Diaw, C., Tiani, A.M.

“…The resettlement of people from human-inhabited protected areas (HIPAs) is a contentious point in the people-and-parks debate. This article illustrates the setbacks that can arise from conservation-and-development projects where these two realms of local reality are separated through resettlement schemes, rather than integrated. …”

Heterologous priming-boosting immunization of cattle with Mycobacterium tuberculosis 85A induces antigen-specific T-cell responses por Taracha, E.L.N., Bishop, Richard P., Musoke, A.J., Hill, A.V.S., Gilbert, S.C.

“…Using either fowlpox virus or DNA priming, there was a significant bias toward induction of CD4(+)- rather than CD8(+)-T-cell responses. These data illustrate the general applicability of priming-boosting vaccination strategies for induction of antigen-specific T-cell responses and suggest that the method may be useful for development of veterinary vaccines.…”

Trees and water: smallholder agroforestry on irrigated lands in Northern India por Zomer, Robert J., Bossio, Deborah A., Trabucco, Antonio, Yuanjie, Li, Gupta, Diwan C., Singh, Virendra Pal

“…This study based on farmer survey data, used remote sensing and spatial hydrological modeling to investigate the importance and role of the poplar trees within the agricultural landscape, and to estimate their water use. Overall, results illustrate a potential for addressing the increasing global demand for wood products with trees grown on-farm within irrigated agroforestry systems.…”

Using the economic surplus model to measure potential returns to international livestock research. The case of trypanosomosis vaccine research por Kristjanson, Patricia M., Rowlands, G.J., Swallow, B.M., Kruska, Russell L., Leeuw, P.N. de, Nagda, S.M.

“…This study illustrates how productivity impacts resulting from livestock research can be measured using a herd simulation model, how the results of this model can be extended spatially using geographic information systems (GIS) to determine the potential increase in livestock production that would result from adoption of a new technology, and how an economic surplus model can be used to value the estimated productivity impacts. …”

Factors affecting efficiency of cotton producers in rural Khorezm, Uzbekistan: Re-examining the role of knowledge indicators in technical efficiency improvement por Karimov, A.A.

“…The results of the restricted stochastic frontier model, which follows a three-stage procedure, demonstrate the presence of technical inefficiency in cotton production. The findings illustrate that the results from the traditional frontier models, which use black box tools, lead to biased outcomes. …”

The importance of international exchanges of plant genetic resources for national crop improvement in Costa Rica por Estrada Garro F, Galluzzi, Gea, Elizondo Porras FY

“…Using Costa Rica as a case and rice and bean as key crops, the paper presents a picture of the dynamics of their genetic resources, both inside and outside of the country, over past years and into the future. It illustrates the extent to which Costa Rica is dependent upon germplasm from other countries for its food security, and how, in a complementary manner, other countries rely upon germplasm from Costa Rica. …”

Methodology in the cassava on-farm trials: An interim evaluation por Lynam, John K.

“…Site selection, farm trial design and analysis, and some illustrative results are included. Trials are currently focussed on: (1) comprehension of the factors determining yields in traditional cassava production systems; (2) determination of the changes in the systems necessary to support the higher yield plateau of the hybrid var.; and (3) determination of the changes necessary to adapt these systems to the requirements of new industrial markets. …”
