Obudu community was the focus to examine the implications of these structures on yam productivity and sustainability. Data was collected through 60 interviews, 2 public meetings, 3 focus group discussions, local informants, review of literature, including secondary and grey literature and keen observation. Our findings reveal a range of indices of respondents’ perception as measures of productivity. The native and the ‘aged’ majority of the population were more conservative in their farming practice exhibiting deeper attachment to traditional practices and ecological wholesomeness with decreasing material productivity and performance in yield outputs, though not so significant. The socially mobile non-natives and the younger demographic groups were open to the modern farming approach targeting the quantity and tons of yam tubers and were not so keen on the overall health and integrity of the ecological system that makes sustainable production and human existence possible. The results emphasize the need to look beyond the improvement in material productivity as other non-material indices of productivity should be explored. More rigorous quantitative and long-term trend analysis should be conducted to assess the productivity performance trend associated with the natural ecological health and yam outputs for the study area.</p></abstract><trans-abstract xml:lang="ru"><p>Социокультурные факторы при производстве ямса в значительной степени формируются традицией, религией, убеждениями, запретами, мифами, духовностью и социальными отношениями внутри общества. Чтобы изучить влияние этих факторов на уровень урожайности ямса, а также на рациональное и экологически устойчивое производство ямса было выбрано сообщество Обуду. Данные были собраны в ходе 60 интервью, 2 общественных встреч, 3 обсуждений в фокус-группах, в рамках бесед с местными информаторами, обзора литературы, включая вторичную и малоизвестную литературу, а также за счет внимательного наблюдения. Наши результаты выявили ряд показателей восприятия респондентами показателей урожайности ямса. Большинство коренного и пожилого населения были более консервативными в своих методах ведения сельского хозяйства, проявляя глубокую привязанность к традиционным методам и экологической чистоте при возделывании корнеплода при снижении производительности и показателей урожайности, хотя и не столь значительных. Социально мобильные респонденты, не являющиеся аборигенами, и более молодые демографические группы проявляли открытость для современных сельскохозяйственных подходов, ориентированных на количество корнеплодов и общий вес клубней ямса, и не были так заинтересованы в сохранении общего благополучения и целостности экологической системы, которая делает возможным рациональное и экологически устойчивое производство в процессе человеческого существования. Результаты подчеркивают необходимость не ограничиваться лишь улучшением показателей материальной производительности, поскольку необходимо изучить и другие, нематериальные показатели производительности. Должен быть проведен более строгий количественный и долгосрочный анализ тенденций, чтобы оценить тенденцию производительности, связанную с естественным экологическим благополучием и урожайностью ямса на изучаемой территории.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рациональное и экологически устойчивое производство</kwd><kwd>социокультурный</kwd><kwd>производство ямса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sustainability</kwd><kwd>socio-cultural</kwd><kwd>yam production</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Грант на проведение исследований на местности был предоставлен программой исследования ямса Национального научно-исследовательского института корнеплодов г.
