“…In developing countries the objective of these schemes often include enhancement of food security and livelihood of smallholder farmers [ 13 , 14 ]. Even yet, farmers adoption of adaptive measures is typically limited or insufficient, necessitating further training and extension services [ 15 ]. Understanding the underlying reasons, including the elements that favor or prevent the adoption of appropriate adjustments, would assist governments in determining whether such a program is required and how it should be planned and targeted.…”

“…The uptake of adaptive measures by farmers is generally partial or incomplete since the adoption process requires more in-depth training and additional financial assistance (Kimathi et al 2021). As governments in various countries recognize that the majority of farmers in their countries have not been adapting sufficiently and efficiently, in order to increase the rate of adaptation uptake, various supportive programs such as extension services to raise farmers' awareness of climatic change and financial support in terms of microcredit are being provided (Shisanya and Mafongoya 2016;Nelson 2020).…”

Changes in living environments due to natural hazards are important indicators that affect livelihood and sustainable development, particularly for those farmers residing in poor and remote regions. The uptake of adaptive measures by these farmers is generally partial or incomplete. Thus, there is a real need to understand better the set of drivers that shapes farmers' decisions of adaptation practices, which help to minimize risks and overcome hazards so that sustainable regional development can be facilitated and maintained. We extend the theoretical framework by adding a psychological driver to the traditional Capital Approach Framework (CAF) to examine the nexus between farmers' perceptions, their adaptive assets (human, physical, financial, social, and natural capitals), and their adaptation strategies. In this study, we use survey data of 916 small-scale Vietnamese farmers to examine the research question by employing a multivariate probit model. Our results suggest that heightened perception increases the propensity of respondents to diversify their income sources away from agricultural activities and engage in better investment management. Government assistance in the form of extension training and microcredit programs demotivates farmers from adaptations, therefore redesignation of these schemes or collaboration with the private sector is necessary. Information obtained from local officers would encourage farmers to widely adapt their livelihood strategies to climate change, we thus suggest that the farmers should utilize this information as much as they can. Along with our finding of the significant impact of farm size on farmers' adaptations adoptions, the "land accumulation" program directly benefits small-scale farmers so that they are motivated to either expand productions or transfer land ownership by participating in the land market. The application of this program may help other countries to avoid land fragmentation and abandonment to ensure farmers' livelihood under climate change.

“…It needs about 25–50 mm of water per week, and this leads to potato response with an increase tuber yield up to 2 t.ha −1 for each 20 mm of irrigation amount applied ( Asfary et al., 1983 ; Fabeiro et al., 2001 ). Its water demand was estimated at 350–800 mm depending on the soil type, irrigation management, cultivar, climates, field and environmental conditions ( Bryan et al., 2013 ; Muthoni et al., 2017 ; Taiy et al., 2017 ; Tolessa, 2019 ; Kimathi et al., 2021 ).…”

Potato productivity (Solanum tuberosum L) is generally influenced by several factors, including water and nitrogen (N), and potato requirement for these factors varies depending on the soil type and potato variety. This research aimed to determine the performance of apical rooted cuttings of potato grown in Mollic Andosols under different nitrogen fertilization and irrigation regimes. The treatments comprised 4 irrigation regimes of 100%, 85%, 75% and 50% of the crop evapotranspiration (ETC), where ETC100% was irrigated based on water depletion in the root zone two days after full irrigation, and 4 nitrogen rates of 0 (N0), 60 (N1), 90 (N2) and 130 kg.ha À1 (N3) applied in splits at 10 (40%), 30 (40%) and 50 (20%) days after planting. The results revealed that the water demand for apical rooted cuttings of potato (ETa) was on average 201.4, 302.1, 342.4 and 402.8 mm under ETC50%, ETC75%, ETC85% and ETC100%, respectively. It was observed that plant height and number of branches significantly (P < 0.001) varied under different N rates with the highest plant height (92.67 cm) and number of branches per potato plant (17) achieved when applying N3. Potato grown under full irrigation (ETC100%) with N3 produced the highest total potato tuber yield (58.28 t.ha À1 ) and marketable tuber yield (54.21 t.ha À1 ). The number of tubers per plant statistically reduced as the N deficit increased, with the maximum tuber number, 23, achieved under N3. It was observed that a significant Pearson correlation (r ¼ 0.7***) existed between tuber number and total tuber yield. The maximum harvest index (HI), 57.12 %, was obtained under ETC50% with N3, while the highest tuber dry matter, 30 %, was observed under N3. To achieve a high tuber yield from apical rooted cuttings of potato in Mollic Andosols, this study recommends an irrigation regime of ETC100% and a nitrogen rate of 130 kg.ha À1 .
