“…The analysis of the effects marginal watch that the fact to be aged driven a growth of the probability of adoption of the improved varieties of sesame of 0.006 point. This result is similar to the one found in Tanzania (Beyene & Kassie, 2015) to the doorstep of 1% for the maize, to Nigeria for the cowpea to the doorstep of 5% (Adéoti et al, 2002), in Ethiopia to the doorstep of 10% for the stones lines (Aklilu & Jan, 2007) in Centrafrique for rice to the doorstep of 1% (Bessane-Mbetid, 2014), to Cameroon for the maize to the doorstep of 5% (Etoundi and Kamgna, 2008), to Nepal to the doorstep of 10% for the adoption of the potato (Kafle & Shah, 2012). This result is also in conformity with the one found in Zambia (Kaliba et al, 2000) for the adoption of improved varieties of maize in the doorstep of 1%.…”

In the Northern region of Burkina Faso, the soils degradation and the irregularity of the rainfall patterns have been the major constraints that affect the food security. The stakeholders developed the initiatives aiming to reduce the effects of the climatic changes. In order to integrate the structures of agricultural researches, the objectives were to assess for farmers preferences on improved sesame seeds, to breed for improved varieties adapted to the soil and the climate; to evaluate and select the most ideal sesame variety of Yatenga. A survey has been done on 126 farmers of two rural communes (Barga and Namissiguima) in the province of the Yatenga. The rate of adoption of the improved varieties of sesame is 83.33%. The econometric results have shown that the decisions of adoption of the varieties improved were based on: age, the level of training, the number of workforce and the number of cattle possessed by the household. In a changing climate marked by cycles of season's disturbances, it is more than necessary to promote improved varieties adopted socio-economic conditions of producers focusing on training farmers to use rationally improved varieties taking into account the recommendations of research.

Potato is mainly tagged as a food security crop in Ethiopia. However, its productivity remains low due to low adoption of improved technologies by smallholder farmers. Duration models, namely, Parametric (Weibull) and Non-parametric (Kaplan Meier) were used to analyze the data gathered from 365 sample farmers. The Non-parametric result revealed that the average duration that potato growers should wait before adopting a new variety is about 3.5 years. The Weibull regression indicated that timely availability of seed, access to labor and irrigation water, land size, and adaptation strategy by farmers are found to be factors curtailing the timeframe to adopt improved potato varieties. The regression analysis revealed that costs of inputs such as manure and compost, environmental and market factors such as drought, pest and disease outbreaks, price variability of potato seed, and quality of potato seed were found to be factors influencing adoption decisions of improved potato varieties by smallholder farmers.

“…Technological interventions ( [4][5][6][7][8][9][10][11]), in general, and irrigation projects ( [12][13][14][15][16][17][18][19]), in particular, often result in a low level of awareness among the target group and in a low level of successful diffusion of the project (i.e., dissemination of knowledge leading to participation) because farmers are rarely consulted a priori about their specific circumstances, priority problems, and expectations. a duration model in the U.S. to estimate the long-term trends in the adoption and diffusion of technologies designed to reduce environmental externalities from agriculture.…”

This paper applies ex ante econometric, cost-benefit, and financial methodologies to increase participation in an irrigation project and predict its financial feasibility and social sustainability in Shahrazoor, Kurdistan, Iraq. I investigated the socio-economic, psycho-cultural, and financial factors that determine participation. The socio-economic part of the econometric analysis showed that the project was appreciated more by poorer and economically weaker farmers who rely on agriculture than by those who rely on livestock activities. The psycho-cultural part of the econometric analysis emphasized that the project was appreciated more by literate farmers who adopt a maximization (rather than habit) approach. The cost-benefit analysis applied to the irrigation project was tailored to poorer and weaker farmers (i.e., costs of the irrigation scheme and benefits from new cultivation patterns were defined with reference to small farms) by including indirect benefits from both irrigation (e.g., flood control) and hydropower (e.g., eliminated GHG emissions), and determined a 7.1% mean internal rate of return; this was affected more strongly by uncertainty in crop prices than by uncertainty in indirect benefits. The financial analysis highlighted values for water prices, financial returns, and loan rates that met government and farmer budgets. A single framework summarized the main relevant social, economic, and financial conditions, and, by including insights from sensitivity analyses, determined the feasibility and sustainability of the irrigation project. Provided that the water price charged to farmers is between 0.32 and 0.57 USD/m 3 , and the loan interest rate paid by farmers is smaller than 3.0%, the irrigation project in Shahrazoor is financially feasible for 13.6% of all reliable economic solutions and socially sustainable for 35.8% of the solutions.
