Abstract Deli Serdang District is among the highest rice producer districts in North Sumatera Province. Unfortunately, climate change and improper cultivation management practices degrade riceland fertility and affect stagnant rice productivity over the years. This study aims to identify the spatial pattern of the limited-factors for riceland suitability and determine land degradation factors and the strategic actions to increase rice production. This study was conducted in 2019 in six districts and interviewed sixty farmers for getting information about riceland degradation issue. The field survey, soil analysis and household-based survey are some methods implemented in this study. The two tools, ArcGIS and SPSS, were used to gain the purposes of the research. The results show that the low status of nutrient availability, root condition and nutrient retention are the main factors of riceland degradation. Besides, this study found that climate change, lack of organic fertilizer implementation, water scarcity and excessive chemical fertilization implementation were significant factors of land degradation based on farmers perception. In addition, some of the strategic actions were frequently implemented to minimize the degradation rate are implementing the minimum tillage, using certified seed, giving a fallow season for riceland and recycling plant residue as organic fertilizer. The study suggests implementing the proper cultivation management practices like Integrated Crop Management (ICM) and Climate Smart Agriculture (CSA) to achieve the sustainability of rice production.

<p>The integrated crop management approach on rice is aimed to increase the productivity on fields with the constraint of limited land area. This present research was aimed to analyze<br />the impact of the implementation of integrated crop management to grain yield and its efficiency on the lowland farming. The study was conducted in three districts representing the lowland rice production center in Bali, i.e. Tabanan, Buleleng and Gianyar, involving 216 respondents, over two cropping seasons. Sampling of the respondents was using stratified simple random method. Data were analyzed using a stochastic frontier production function with the Maximum Likelihood Estimation (MLE) method. The results showed that the aggregate of rice production was affected by land area, amount of seeds, N fertilizer, organic fertilizer, pesticides, labor and age of seedling. Rice yield was higher in the dry season applying legowo planting pattern, followed by intermittent irrigations, IPM and planting varieties other than IR64. Technically, both ICMFS alumni farmers and non ICM-FS alumni were considered efficient, with an efficiency rate of more than 70 percent, but only<br />ICM-FS alumni farmers allocated the inputs efficiently, and therefore economically move efficient. Socio economic factors which were significantly affected the aggregate technical<br />inefficiencies were age of farmers, level of education, farming experiences, and the number of land plots. Technical inefficiency of the lowland rice farming was lower when ICM-FS alumni farmers work on their own lands.</p>

SAMARICA is the second district of Occidental Mindoro province in the Philippines having a vast land area for rice production. It supports the rice milling sector of the province with promising facilities for postharvest of rice. This study investigates the rice farmers’ adoption level of integrated crop management practices (ICMPs). The adoption ICMPs aims to promotes farm productivity and efficiency. A total of 404 rice farmers participated in this study selected through a multi-stage sampling technique. Quantitative data were generated from the survey questionnaire and were analyzed using Descriptive Statistics. Partial Least Square Structural Equation Modeling (PLS-SEM) was used to analyze the relationship between production and postharvest practices. The results revealed that rice farmers have “very high” adoption of rice production technologies except for water technologies and intermittent irrigation with “high” adoption level. In terms of postharvest, there is “very high” adoption of mechanized harvesting and recommended moisture content for rice but “moderate” adoption for rice parboiler, dying machines, and threshing of rice right after harvest. On the other hand, a statistically significant evidence was found for production technologies as predictor of postharvest technologies, specific for the care and management of rice (β =0.55; P<0.01).

Rice farming is highly dependent on environmental factors such as rainfall and temperature. Rice yield is affected by changes in these climatic elements. Rice farmers’ perceptions of the changes in climate are important determinants of the management practices they use in reducing the effects on rice production. This study assessed the perceived effects of climate change on rice production among farmers. A multistage sampling procedure was used to obtain a sample of 522 farmers. Data were obtained with the aid of structured questionnaire. The data were analyzed using both descriptive and inferential statistics. Findings revealed that majority (94%) of the respondents were males. They were married (88%) and had farming as a major occupation (89%). They perceived that climate change was posing risks to rice production (X = 2.16), would lower rice production (X = 2.07) and would continue to affect storage of rice (X = 2.01). The study determined a significant relationship (p<0.01) between farmers’ perceived effects of climate change and rice yield. It was concluded that positive perception can lead to high adoption of climate change adaptation practices. The climate change knowledge-base of the farmers needs to be improved through more sensitization on climate smart agriculture.

In this study, we aimed to improve rice farmers’ productivity and profitability in rainfed lowlands through appropriate crop and nutrient management by closing the rice yield gap during the dry season in the rainfed lowlands of Indonesia. The Integrated Crop Management package, involving recommended practices (RP) from the Indonesian Agency for Agricultural Research and Development (IAARD), were compared to the farmers’ current practices at ten farmer-participatory demonstration plots across ten provinces of Indonesia in 2019. The farmers’ practices (FP) usually involved using old varieties in their remaining land and following their existing fertilizer management methods. The results indicate that improved varieties and nutrient best management practices in rice production, along with water reservoir infrastructure and information access, contribute to increasing the productivity and profitability of rice farming. The mean rice yield increased significantly with RP compared with FP by 1.9 t ha–1 (ranges between 1.476 to 2.344 t ha–1), and net returns increased, after deducting the cost of fertilizers and machinery used for irrigation supplements, by USD 656 ha–1 (ranges between USD 266.1 to 867.9 ha–1) per crop cycle. This represents an exploitable yield gap of 37%. Disaggregated by the wet climate of western Indonesia and eastern Indonesia’s dry climate, the RP increased rice productivity by 1.8 and 2.0 t ha–1, with an additional net return gain per cycle of USD 600 and 712 ha–1, respectively. These results suggest that there is considerable potential to increase the rice production output from lowland rainfed rice systems by increasing cropping intensity and productivity. Here, we lay out the potential for site-specific variety and nutrient management with appropriate crop and supplemental irrigation as an ICM package, reducing the yield gap and increasing farmers’ yield and income during the dry season in Indonesia’s rainfed-prone areas.

A lack of adaptive capacities for climate change prevents poor farmers from diversifying agricultural production in Bangladesh’s drought-resilient areas. Climate change adaptation strategies can reduce the production risk relating to unforeseen climatic shocks and increase farmers’ food, income, and livelihood security. This paper investigates rice farmers’ adaptive capacities to adapt climate change strategies to reduce the rice production risk. The study collected 400 farm-level micro-data of rice farmers with the direct cooperation of Rajshahi District. The survey was conducted during periods between June and July of 2020. Rice farmers’ adaptive capacities were estimated quantitatively by categorizing the farmers as high, moderate, and low level adapters to climate change adaptation strategies. In this study, a Cobb–Douglas production function was used to measure the effects of farmers’ adaptive capacities on rice production. The obtained results show that farmers are moderately adaptive in terms of adaptation strategies on climate change and the degree of adaptation capacities. Agronomic practices such as the quantity of fertilizer used, the amount of labor, the farm’s size, and extension contacts have a substantial impact on rice production. This study recommends that a farmer more significantly adjusts to adaptation strategies on climate change to reduce rice production. These strategies will help farmers to reduce the risk and produce higher quality rice. Consequently, rice farmers should facilitate better extension services and change the present agronomic practice to attain a higher adaptation status. It can be very clearly seen that low adaptability results in lower rice yields.

Canopy management practices in vineyards, such as sprawling systems and shoot trimming, can change the accumulation of metabolites in grapes. The use of elicitors of biological origin on grapevines of Vitis vinifera red grape varieties may also modulate the chemical composition of the berries. These modifications are often observed in the accumulation of phenolic compounds, including pigments. Both technical approaches are alternatives involved in minimizing the effects of global climate change in warm areas. The increase of temperature related to climate change accelerates the accumulation of sugars, but produces unbalanced grapes. This work establishes the use of button sensors to monitor the climate changes occurring at grape cluster level. Together with climate monitoring, conventional instrumental analytical techniques are used to follow up the chemical composition and the phenolic fraction of grapes in four different production areas in Spain. The effect of either treatment seems variable and to be affected by external factors besides the treatment itself and the climate conditions. While there is a fine effect that correlates with the use of elicitors in varieties like Merlot and Tempranillo, there is minimal improvement observed in Tintilla de Rota. The total phenolic index increases were between 2.3% and 11.8% in the first two parcels. The same happened with the vineyard’s canopy management systems, with increased pigment accumulation and the total phenolic index rising (37.7% to 68.7%) after applying intense shoot trimming, or a variation in sugar concentrations when using sprawl conduction. This study aims to provide viticulturists and oenologists in particular, and farmers in general, with data on the field regarding the use of alternative sustainable practices in the cultivation of grapes. The techniques used involved 100% natural products without adjuvants. The benefits obtained from applying some of these practices would be to produce technically mature grapes despite climate changes, and the elaboration of more balanced wines.

E.P. Meinecke, a noted plant pathologist and staunch supporter of conservation, authored an influential article about the impacts of tourism on redwood trees. In the Effect of Excessive Tourist Travel on the California Redwood Parks, published in 1929, Meinecke found that soil compaction by tourists had a negative impact on tree roots and his recommendations for amelioration were both logical and laced with philosophical ideals. We revisit that report with a modern perspective by reviewing his findings and suggestions, and by comparing his ideas with modern research and tourism management practices. One of Meinecke’s greatest concerns was the advent of the automobile and its ability to bring more people to redwood groves. We take that concern to the next logical step and discuss potential impacts of climate change on redwood trees.

In Ethiopia, the practice of land management started three decades ago in order to address the problem of land degradation and to further boost agricultural production. However, the impact of land management practices in curbing land degradation problems and improving the productivity of the agricultural sector is insignificant. Various empirical works have previously identified the determinants of the adoption rate of land management practices. However, the sustainability of land management practices after adoption, and the various factors that control the sustainability of implemented land management practices, are not well addressed. This study analyzed the factors affecting the sustainability of land management practices after implementation in Mecha Woreda, northwestern Ethiopia. The study used 378 sample respondents, selected by a systematic random sampling technique. Binary logistic regression was used to analyze the quantitative data, while the qualitative data were qualitatively and concurrently analyzed with the quantitative data. The sustained supply of fodder from the implemented land management practices, as well as improved cattle breed, increases the sustainability of the implemented land management practices. While lack of agreement in the community, lack of enforcing community bylaws, open cattle grazing, lack of benefits of implemented land management practices, acting as barrier for farming practices, poor participation of household heads during planning and decision-making processes, as well as the lack of short-term benefits, reduce the sustainability of the implemented land management practices. Thus, it is better to allow for the full participation of household heads in planning and decision-making processes to bring practical and visible results in land management practices. In addition, recognizing short-term benefits to compensate the land lost in constructing land management structures must be the strategy in land management practices. Finally, reducing the number of cattle and practicing stall feeding is helpful both for the sustainability of land management practices and the productivity of cattle. In line with this, fast-growing fodder grass species have to be introduced for household heads to grow on land management structures and communal grazing fields for stall feeding.
