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.

Adaptation Practices

Rice productivity and sustainability are threatened by both biotic and abiotic stresses, the effects of which can be further aggravated by dramatic changes in global climate. The most viable option for rice farmers is to use climate change adaptation practices. This study therefore investigated the determinants of use of climate change adaptation practices among rice farmers in Kebbi State, North-West, Nigeria. Data were collected from a sample of 279 farmers selected using a multistage sampling procedure. The results of the data analysis revealed that the farmers used improved rice varieties, intercropping, recommended rates of fertilizers and other chemicals as climate change adaptation practices among others. Education, climate change awareness, and extension contact significantly influenced the use of climate change adaptation practices among the farmers. Other determinants of use of climate change adaptation practices among the farmers were years of cooperative membership, affordability, farming experience, weather information and farm size. It was concluded that use of climate change adaptation practices was determined by socioeconomic, institutional and technological characteristics. It is recommended among others that government policy should be geared towards encouraging the farmers especially the younger ones to acquire more formal education, larger farmlands and more climate change awareness.

The study examined the effect of climate change adaptation practices on rice farmers’ level of living in North-West, Nigeria. It targeted Sokoto, Kebbi and Zamfara States in the North-West, Nigeria that are among the major rice producing States in the country. A multistage sampling procedure was used to obtain a sample of 522 farmers for the study. The data were obtained with the aid of structured interview schedule were analysed using both descriptive (frequency counts, percentages, ranges and means) and inferential (Chi-square) statistics. Findings of the study reveal that the majority (96%) of the respondents had their income from rice production, within the ₦50,000.00 to N499,999.00 (143 to 1,429 USD) range. The mean rice income was ₦308,742.00 (882 USD). The majority (84.48%) and (77.40%) of the respondents used improved rice varieties and intercropping as climate change adaptation practices, respectively. Other climate change adaptation practices used by the rice farmers included moderate use of fertilizers (93.10%) and other chemicals (89.85%), as well as use of organic manure (99.43%). The farmers also adjusted the planting calendar through early planting (92.34%) and early harvesting (93.10%). Similarly, the majority (89.85%) of the respondents made mounds and ridges across slopes while 96.17% and 89.08% used rivers/streams and dug wells for irrigation. About 51% of the rice farmers spent ₦5,000.00 - ₦370,999.00 of their rice income on vehicles. 54% spent ₦8,000.00 - ₦92,299.00 of their rice income on electronics and only about 14% spent ₦4,000.00 - ₦102,999.00 of their rice income on land and housing. There was a significant (X2 = 258.6325; p < 0.00) relationship between farmers’ use of climate change adaptation practices and their level of living. The study concluded that rice farmers’ use of climate change adaptation practices could lead to improvement in their rice income and level of living.

Yield Gap

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.

Impacts Of Climate Change

<p>Climate change, manifested as temperature rise and rainfall change, will pose significant challenges to rice farmers, leading to a possible rice shortage under a changing climate. This research aims to understand the impacts of climate variability and change on rice production through the rest of this century using Representative Concentration Pathway (RCP) scenarios, and combination of statistical and system dynamic modelling. The area of study is West Nusa Tenggara, Indonesia. Wetland and dryland farming types are assessed separately because they have different rice varieties and different agricultural practices.  Overall, the research seeks to answer the question: How will climate change and climate variability affect rice production? Additional questions investigated are (1) What are the most significant supply uncertainties associated with a changing climate? and (2) What are possible solutions for reducing the impacts of climate change on rice production?. To answer these research questions, this study deals with three main research areas. First, based on observed data (1976-2011), this study developed regression-based statistical models in understanding the impacts of climate change on rice yield in West Nusa Tenggara. Statistical models find that the negative impacts of increased minimum temperature on rice yield are statistically significant.   By contrast, the effects of maximum temperature on rice yield are not statistically significant. A key reason for this is that the highest maximum temperature (32⁰C) in the observed period (1976-2011) was lower than 35⁰C, a rice threshold for maximum temperature. By 2090 (2077-2100), rice yield in wetland and dryland is projected to decrease by about 3% (RCP2.6 scenario), 4% (RCP4.5 scenario), 5% (RCP6.0 scenario) and 14% (RCP8.5 scenario).  Second, a system dynamics model was developed to assess the impacts of climate change on three issues including rice yield, harvested areas and rice production by 2090 (2077-2100). After embedding statistical models and estimating the impacts of maximum temperature on rice yield based on existing studies, the impacts of climate change on rice yield are projected. The system dynamics model is also equipped by August SOI to estimate the impacts of climate change on the timing of monsoon onset i.e the beginning of planting seasons. For assessing harvested areas under a changing climate, the system dynamics model is equipped by a mathematical relationship between seasonal rainfall and harvested areas.  Because the system dynamics model includes the impacts of high maximum temperature, the projected loss of rice yield in wetland and dryland is relatively higher compared to that in statistical models. It is projected that rice yield loss will be about 3% (RCP2.6 scenario), 6% (RCP4.5 scenario), 10% (RCP6.0 scenario) and 23% (RCP8.5 scenario) by 2090 (2077-2100). Likewise, rice production loss in wetland and dryland is projected to be about 1% (RCP2.6 scenario), 2% (RCP4.5 scenario), 7% (RCP6.0 scenario) and 19% (RCP8.5 scenario) by 2090 (2077-2100). The projected loss of rice production is relatively lower than rice yield loss as wetland harvested areas are projected to experience a slight increase about 3% by 2090 (2077-2100) under a changing climate. This also means that the ranking of the impacts of climate change from the most significant to the least significant is its impact on rice yield, rice production and harvested areas.   Third, policy options in overcoming the impacts of climate change on rice production are assessed. This study suggests that research on finding rice varieties with three main traits: heat tolerance, short growth duration and high yield is key to balance rice demand and rice supply in West Nusa Tenggara by 2090 (2077-2100). A failure to improve rice yield in such ways is likely to lead to significant reductions in rice supply in the face of climate change.  This study makes theoretical contributions, including the development of statistical models for understanding the impacts of climate change on rice yield and a causal system for investigating the impacts of climate change on rice yield, rice production and harvested areas. Again, the combination of statistical and system dynamics modelling simultaneously investigates the impacts of climate change on rice yield, rice production and harvested areas. This means that this study provides a more holistic view of the impacts of climate change compared to existing studies.  This study also offers practical contributions, advising that declining rice research should be avoided under a changing climate, and suggesting that farming intensification (more climate-resilient rice varieties) is more effective than farming extension (area expansion) in sustaining rice production under a changing climate. Again, research on developing more resilient-climate rice varieties is possible as projected rice yield in sustaining rice production by 2090 (2077-2100) is similar to rice’s yield potential.</p>

The Impact

Better management practices (BMPs) as a sustainable approach made it attractive for growers to control the provision of pollutants from agricultural activities as well as enhance the financial return. The experiments of cotton production were conducted in four different regions of Punjab in cotton-growing years 2017-2019. The objective of the study was to evaluate the potential impact of BMPs among cotton farmers by rationalizing the use of input resources (viz., seed, fertilizers, pesticides and water). The data were collected from randomly selected adopters of BMPs (n = 400) and non-adopters of BMPs (n = 100) through a well-structured pretested questionnaire using a multistage sampling procedure from four different regions of Punjab province. Descriptive analysis was employing an independent two-sample t-test to evaluate the significant effect of BMPs on the utilization of input resources and profitability of cotton production between adopters and non-adopters of BMPs. The results indicated that adopters of BMPs were efficiently used input resources (at p &le; 0.001 &amp; p &le; 0.01) and significantly enhanced the average cotton yield (855.09 kg acre-1) in Punjab, while non-adopters of BMPs had a significantly high cost of production by 11% (35,655 PKR acre-1) and output was lower by 15% (751.70 kg acre-1) under conventional farming for cotton cultivation. The economic analysis revealed that the average gross income gained by adopters of BMPs was significantly high by 11% (72,648 PKR acre-1 at p &le; 0.001) with the maximum net return of 36% (40,785 PKR acre-1 at p &le; 0.001) as well as a good B:C (1.28) as compared to non-adopters of BMPs. This study provides useful information about the potential impact of BMPs among cotton farmers even without the extra use of inputs. It is concluded that precision in inputs and management practices with lower input costs can significantly improve cotton productivity leading to uplift the farmers&rsquo; profit.

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.

The study determined rice farmers’ perceived resilience capacity to climate change in Ebonyi State, Nigeria. Multistage sampling procedure was employed in selecting 104 respondents for the study. Data were collected using semi-structured interview schedule. Percentage, mean and standard deviation were used in presentation of results. Results showed that areas of rice farmers’ resilience capacity to climate change were: planting improved varieties of seed ( x̄ =4.76), utilisation of soil that retains water longer ( x̄ =3.33), access to very fertile soil for rice production ( x̄ =3.28) and good amount of solar radiation ( x̄ =3.21). However, areas in which respondents’ did not perceive as sources of resilience capacity were: favourable government policies ( x̄ =2.37), good marketing policies ( x̄ =2.57), and access to insurance ( x̄ =2.84). Policies such as crop insurance, appropriate marketing and infrastructural policies that help rice farmers cope with negative effects of climate change be enacted and implemented. Such policies should address issues of marketing and insurance of rice farms against disasters such as flood, drought, diseases and pests’ infestation.

This study employed the propensity score matching approach to empirically assess the effects of climate smart agriculture participation and climate change adaptation response on the technical efficiency of rice production. Observational data were collected from in-depth interviews with 352 rice farm households in the Mekong Delta, Vietnam. The findings indicate that 71% of local farmers adapted their rice farming to climate change related to salinity intrusion and drought, while 29% of farmers did not. Additionally, only twenty-two rice farmers were typically chosen as participants in the climate smart agriculture pilot program by local government and institutions. The choices for adaptation response and climate smart agriculture participation are significantly influenced by agricultural extension services, belief in climate change, the area of farming land, as well as geographical locations (e.g., province and access to water sources). The results also reveal that climate change adaptation response, including climate smart agriculture participation, played a crucial role in improving technical efficiency of rice production by 13%–14% compared to no adaptation response. Regarding the individual effect of climate smart agriculture participation, participants could achieve higher technical efficiency by 5%–8% compared to non-participants.

Abstract To achieve the challenges raised in Agenda 2063 and the Malabo Declaration, new agricultural techniques need to be promoted. Practical approaches to implement climate smart agriculture and sustainable agriculture, able to deliver at field level, are required. These include sustainable soil and land management that allows different user groups to manage their resources, including water, crops, livestock and associated biodiversity, in ways that are best suited to the prevailing biophysical, socio-economic and climatic conditions. The adoption of locally adapted sustainable soil management practices is needed to support climate change mitigation and adaptation from the agricultural perspective. In this sense, Conservation Agriculture (CA) can be adapted to local conditions, and help achieve the key objectives. The application of CA principles brings multiple benefits, especially in terms of soil conservation, but also for mitigating climate change. In fact, CA has the ability to transform agricultural soils from being carbon emitters into carbon sinks, because of no-tillage (NT) techniques and the return to the soil of diverse crop biomass from above-ground parts of plants and from diverse roots systems and root exudates. Similarly, fossil energy use decreases due to the reduction in agricultural operations, and so less CO2 is emitted to the atmosphere. Lower greenhouse gas (GHG) emissions in CA also result, because of reduced and more efficient use of inputs. Scientific studies confirm the sequestration potential of increased soil organic carbon (SOC) stocks on croplands in Africa on each of the continent's major bioclimatic areas. Coefficients of SOC sequestration for Africa are presented in this chapter.

AbstractWe evaluate the effects of climate change on Vietnam's rice market. Results suggest that under a low-emission scenario and without interventions, rice production would drop by as much as 18% by 2030 relative to the 1980–1999 average. Farm and wholesale prices would increase by 1.86%, causing domestic demand to fall by 0.38%. The export sector would experience a rise of 6.94% in export free-on-board prices and a drop of 55.36% in export quantities. Farmers would experience a sales loss of 16.02%, whereas wholesalers would see a sales gain of 1.48%. For exporters, their sales loss would amount to 48.42%.
