Recent studies highlight a growing concern over the limited adoption of climate smart agricultural (CSA) practices despite their potential benefits on adaptation, mitigation and productivity. Literature indicates several factors behind the lack of adoption including socio-demographic and economic conditions, agro-ecological scales and the nature of the practices. This paper examines to what extent and under which conditions such factors influence the adoption of CSA practices at farm, household and community level across three study sites in different continents: Vietnam, Nicaragua and Uganda. While cost benefit analysis (CBA) is employed to assess the farm-level profitability of CSA practices, the aggregate community impact disaggregated by different groups of farmer typologies with specific socio-economic features is derived from the adoption rate estimated by the relative advantage of practices and the income level of each group. Our main findings show great variation of farm-profitability of CSA practices across scales. Similar practices could generate different profitability depending on crop typologies, input access and prices, household types and local context. Regarding the aggregate profitability of CSA practices at regional scale, we found that under particular conditions, relevant factors of adoption matter to the adoption pattern and thereby affects the ranking. Such conditions include (i) high income inequality, (ii) large profitability gap of prioritized CSA practices, and (iii) large proportion of cost and benefit of the practices in the level of income. This study contributes to enhancing the prioritization process of CSA practices and provides practical guidance for research and policy to tailor the investment to appropriate end-users to assure the greatest impact for the community.

“…Otro factor importante que debe ser considerado en una posible explicación del proceso de adopción del sistema de abonera es la rentabilidad del sistema en relación al uso alternativo de la tierra (Cuadro 4) (Sain, et al, 1992). Se calaron la rentabilidad de corto y de largo plazo del sistema de abonera comparándolo con la rotación tradicional de maíz y descanso (2 años de maíz y 4 años de descanso).…”

The soil, nutrient and water conservation is the main problem faced by farmers and investigators under the corn crop-based systems in Central America and Mexico. Several farmers from Honduras have come up with an efficient technology for the corn planted on hills, in which the bean manure is planted in rotation with corn during the dry season. The results from the conducted survey, at the Departamento de Atlantida in Honduras, indicate that 66 % of the farmers grow most of the corn through the protective mat produced by the beans during the rainy season. Among the advantages of this rotation, compared to the traditional burned and cleared land, are the higher yields with les ser dependency of external imputs, shorter rest periods, lower land preparation costs, less soil erosion and lower risk of drought damages. The problems linked to the diffusion ofthe system include the risk ofland slides and a higher plague's incidence (rats) on the corn planted through the manure mat. Usually, the amount of land available in the regionalland markets is the determining factor on the diffusion of this system, and not the size of the farm nor the form of land tenancy.

“…The use of green manures may help attain all of these aims because they can improve soil fertility and reduce water evaporation and erosion by covering the soil and through the reincorporation of Nitrogen-rich organic matter. They can also provide food for livestock and human consumption (Sain and Buckles, 1998; Astier et al ., 2012), and increase biological and functional diversity within plots (Bunch, 2012; Nabel et al ., 2018; Val et al ., 2019). However, the adoption and pertinence of green manures largely depends on space availability (especially within small plots), the intensity of interspecific competition, seed availability and cost, and the cultural use of green manures (Bunch, 2012).…”

Green manures are a promising alternative for achieving the sustainable production of maize in the face of low soil fertility and increasingly long canicule periods, particularly in rainfed systems associated with the reproduction of local agrobiodiversity. However, it is necessary to investigate what are the advantages and disadvantages associated with different species of native and exotic pulse, as well as their overall contribution to the sustainable production of maize landraces. In order to do so, we followed the MESMIS method to assess five species of pulse (three native and two exotic) grown with maize in two plots with different soil conditions. This was done in the seasons of 2017 and 2018 the municipality of Villa de Zaachila, Oaxaca, a site with remarkable biological, agricultural and cultural diversity. A fully randomized complete block design was implemented with 11 treatments and three repetitions in the two plots. The output variables of the experiment were: land equivalence ratio, interspecific aggressiveness, content of soil organic matter, decomposition rate, plant survival rate and plant dry biomass. We also evaluated quantitative or qualitative indicators of cost, adaptability and contribution to food security. For all the possible maize-pulse combinations, except for one, polyculture outperformed maize and pulse monocultures. Exotic pulses (Crotalaria junscens spp. and Dolicho lablab) had a better performance in biomass, reincorporation of organic matter and possible nitrogen fixation, as well as greater resistance to drought in the second cycle. The native pulses (Phaseolus vulgaris and Phaseolus coccineus), however, had a greater acceptance and economic output and are important for the food security in our study site. Our results provide quantitative and qualitative elements to design combined schemes of green manures associated with maize that would help tackle current challenges regarding maize productivity, food security and response to climate change.
