Profitability of forage production in smallholder peri-urban dairy production systems por Agyemang, K., Dogoo, D.L., Makun, H.J.

“…Synthesis of the resulting data on labour inputs, forage yields, feed intakes, milk yields, value of outputs and cost of inputs such as seeds and fertilizers showed that for the semi-intensive smallholder and zero-grazed models considered in this study, the margin or profit from using home-grown fodder was 5-8 times the cost of acquiring the feed. …”

Soil and water management for rice production in Nigeria por Olaleye, A. O., Osiname, O. A., Cofie, Olufunke O.

“…However, considering the top and subsoil clay contents, these soils are only marginally suitable (S3) for rice production. Soil texture, soil surface relief, groundwater level, as well as number of days of submergence significantly affected the growth and grain yield of rice on lowland soils while clay contents in the subsoil is a significant factor in water retention for upland rice cultivars. …”

Modeling inland valley suitability for rice cultivation por Masoud, J., Agyare, Wilson Agyei, Forkuor, Gerald, Namara, Regassa E., Ofori, E.

“…These were used to model for five suitability classes (highly suitable, suitable, moderately suitable, marginally suitable and not suitable). The model results based on parameters having equal weights showed that 0.5% and 11.8% (BAR); and 1.4% and 21.4% (WR) of the area were highly suitable and suitable respectively. …”

Metering of agricultural power supply in West Bengal, India: who gains and who loses? por Mukherji, Aditi, Das, B., Majumdar, N., Nayak, N.C., Sethi, R.R., Sharma, Bharat R.

“…Results suggest that the majority of the pump owners benefit from the reforms in two ways: first by having to pay a lower electricity bill for same usage and second through increased profit margins by selling water. This is because in response to the changed incentive structure, water prices rose sharply by 30-50% immediately after metering. …”

Use of GIS for optimizing a collecting mission for a rare wild pepper (Capsicum flexuosum Sendtn.) in Paraguay por Jarvis, Andy, Williams, K, Guarino, Luigi, Caballero, PJ, Mottram, G

“…A model to prioritize areas for collecting germplasm was constructed by combining (1) a prediction of the species' geographic distribution based on the climate at previous collection points, (2) the distribution of forest margins (the species' natural habitat) and (3) areas accessible by road. …”

Impacts of policies and technologies in dryland agriculture: Evidence from northern Ethiopia por Pender, J.L., Gebremedhin, Berhanu

“…The increase in farming intensity due to these factors has limited impact on total crop production due to low marginal product of labor in crop production, limited productivity impact of inputs such as fertilizer in the moisture-stressed environment of Tigray, and limited adoption of such in-puts. …”

Asia 2011-2015 por International Center for Tropical Agriculture

“…CIAT Asia’s research activities stretching back 30 years highlights significant research outcomes that have contributed to improve the livelihoods of many marginalized poor communities in the region. The current content and diversity of CIAT activities in Asia, the nature of its funding, and the major programmatic shifts within the Consultative Group on International Agricultural Research (CGIAR), provide an excellent opportunity to reconsider the future of CIAT research in Asia. …”

Tropical forages program = Programa de forrajes tropicales por Peters, Michael

“…CIAT aims to help farmers by developing and utilizing a range of eco-efficient forage options that can be grown under a range of favorable to marginal environments in the tropics. In view of the Center's expertise across different production systems, CIAT's tropical forage research has an explicit global focus, with strategic research capacity in South America, Central America and the Caribbean, Eastern Africa, and Southeast Asia. …”

Ganadería y deforestación en América Latina Tropical: Qué podemos hacer? por Rivas Ríos, Libardo

“…Short-term trends show that livestock production is becoming an increasingly important factor in regional development, possibly because of the combined effect of increasing the forages on offer and planting crops better adapted to the environmental and economic conditions of marginal areas and the decreasing interest of the State in expanding the agricultural frontier. …”

Productivity and welfare effects of Nigeria's e-voucher-based input subsidy program por Wossen, T., Abdoulaye, Tahirou, Alene, A., Feleke, S., Ricker-Gilbert, J., Manyong, Victor M., Awotide, B.A.

“…The benefit–cost ratio of 1.11 suggests that the program is marginally cost-effective. Overall, our results suggest that while improving average productivity is a good outcome for improving food security, improving the distributional outcome of the program by targeting the most disadvantaged groups would maximize the program’s contribution to food security and poverty reduction.…”
