Introduction

Women’s involvement in agriculture and their contributions to food security has been widely recognized in the developing countries. Women play a key role in improving agricultural productivity and food security in the farming communities (Agarwal 2013; Aly and Shields 2010). In the last few decades, women’s involvement, access to productive resources, and decision-making roles in agriculture and allied sectors have been the focus areas of research and development in the global south. Many studies claim that differences in men and women’s responsibilities, priorities, and access to resources and services at the community and household levels are responsible for the gender gap in agriculture in many developing countries (Quisumbing et al. 2014; FAO 2011). A clear linkage has been shown among social, economic, and gender dimensions in agriculture (Peterman et al. 2014; FAO 2010a).

Agriculture is one of the most vulnerable sectors to climate change impacts. Within agriculture, however, several studies highlight that women are likely to be affected more than men by climate impacts, especially in the developing countries where their involvement in agriculture is high (Goldsmith et al. 2013; MacGregor 2010; UNDP 2013; Goh 2012; Nellemann et al. 2011). Most of this gender gap analysis in agriculture in the context of climate change have been limited to access to resources and decision making (Kristjanson et al. 2017). However, the labor-intensive roles that women play in agriculture from sowing, weeding, to harvesting also determine the nature and severity of climate change impacts they face. Climate change impacts such as decreasing supply of crop residues and biomass for energy and livestock feed, increasing severity of weeds, crop re-sowing/transplanting requirement, and loss of crop yields are likely to affect women more, given their involvement in related activities (Bradshaw and Linneker 2017; Nelson and Huyer 2016). Thus, there is a need to understand climate change impacts on women based not just on their social, cultural, and economic characteristics but also their role and responsibilities in specific agricultural activities (Nightingale 2011; Morton 2007).

The climate-smart agriculture (CSA) approach is emerging as a new paradigm for adapting agriculture to the changing climate. This approach seeks solutions that improve agricultural productivity, build resilient food production systems, and reduce greenhouse gas emissions (FAO 2010b; Steenwerth et al. 2014). CSA includes a range of technologies, practices, and services to minimize the impact of climate change in agriculture. These CSA options range from a simple adjustment in crop management practices to the transformation of agricultural production systems to adjust to new climatic conditions in a particular location (Khatri-Chhetri et al. 2017; Vermeulen et al. 2012; Howden et al. 2007).

However, the efficacy of CSA options in terms of its benefits to both men and women stands to lose out if the gender gap in agriculture is not taken into account. (Nelson and Huyer 2016). For instance, the level of women’s involvement in agriculture, such as their labor contribution in different agricultural activities (from land preparation to crop harvesting), can have significant implications for the adoption and sustainability of the CSA approach. There are plenty of suggestions for gender-differentiated climate change adaptation strategies in agriculture. Improving women’s access to productive resources, finance and knowledge, promoting off-farm employment, and capacity building on adaptation options can empower them to adapt to a changing climate (Huyer et al. 2015; Edmunds et al. 2013; Chaudhury et al. 2012; Huyer 2016). While the role of CSA in agriculture has been widely discussed, its potential to help women in reducing their labor burdens in particular is not clear.

This paper therefore presents a systematic approach to assess the labor-reducing potential of selected CSA technologies and practices. The objective is to highlight hotspots of women in agriculture, climate risks, and poverty; assess CSA interventions relevant for women in two of these hotspots, based on their role in agriculture and factors affecting the role; and evaluate some of the CSA technologies on their labor-reducing potential for women in agriculture. The study was conducted in Nepal, a country characterized by low-ranked gender-related development indicators and increasing feminization of agriculture due to male out-migration (UNDP 2016; CBS 2013a; Gartaula et al. 2010; Tamang et al. 2014).

Methods and data

Identification of hotspots

Three indicators were used to map women in agriculture–poverty–climate risks hotspots across Nepal. The first indicator was women’s involvement in agriculture which was calculated as the percentage of women in agriculture in the district multiplied by a weight. The weight was the proportion of total number of women involved in agriculture in the district compared to that of the country. Data for this indicator was collected from the national population and housing census survey in 2011. Participation in agriculture also included forestry and fishing industries. The second indicator was climate risk exposure at the district level developed by the Ministry of Environment, Government of Nepal. This exposure indicator included annual temperature and rainfall trends, droughts, floods and landslide risks, and population dependency in natural resources and other risks factors (GoN 2010). The third indicator was the district level poverty (% of population under poverty line). The poverty levels were taken from the census data, which was conducted by the Government of Nepal in 2013 (CBS 2013b).

The hotspots were identified by overlaying women’s participation in agriculture with climate risk exposure and poverty levels using a GIS (geographic information system) tool. Since the study focused on women’s participation in agriculture, 50% weight was given to this indicator while a weight of 25% was given to each of the other two indicators. All three indicators—women’s participation in agriculture, climatic risks and poverty level—were combined and normalized between 0 and 1 values. Using the “Jenks Natural break” method in GIS, the district values (combining women’s participation in agriculture, climate exposure, and poverty) were categorized as low (below 0.4), medium (0.4–0.65), and high (more than 0.65). Districts under the “high” category were defined as the hotspots, where both the women’s participation and the climate risks and poverty were categorized as high.

Assessment of women’s role in agriculture

Two women–agriculture–climate change vulnerability hotspot districts (Rupandehi and Chitwan) were randomly selected for a more detailed assessment. Gender disaggregated data on labor contribution was collected from a cross-section survey of randomly selected 215 agricultural households in 2013/2014. Quantitative data was collected using a questionnaire on men and women’s role in different agricultural activities such as land preparation, crop sowing, tillage, weeding, harvesting, and threshing in major crops. Participation has been measured in terms of labor days contributed to particular agricultural activity.

To compare men and women’s participation in agricultural activities, we compared the average labor contribution to each agricultural activity from land preparation to crop harvesting using mean comparison test (t test). Additionally, to understand variables affecting women’s participating in agriculture, a multiple regression model was run using total labor contribution by women in different agricultural activities (dependent variable) and independent variables such as landholding size, family size, main occupation of household head, gender of household head, and non-agricultural income.

Potential benefits of CSA options for women

To identify a list of currently adopted and potential CSA technologies for the study areas, focus group discussions were conducted with five women farmers’ groups in each research location. In addition, a review of CSA-related literature was also conducted. The technologies were identified based on the dominant crops in these regions (MoAD 2015) (Table 1). The group participants were also asked about the potential impact of the identified CSA technologies on labor, income, and yield.

Table 1 Technology adoption for three major crops in the study areas

The study used five major indicators including gender to assess the potential benefits of CSA options in the study areas (Table 2). For each technology and indicator (except environment), primary data was used for calculation of an index (details in Annex 1). Secondary information was used to calculate the environment index using a study from Pathak and Aggarwal (2012) about low carbon technologies for agriculture. All CSA technologies were evaluated by comparing with and without technology intervention scenarios by using an index where the value for farmers’ conventional practice (FP) is 100. For the objective of this paper, we have mainly focused on the gender indicator which highlights the change in women’s involvement in agricultural activities due to the introduction of CSA technologies and practices. Technologies which reduce women’s labor contribution including improvement in productivity and income have been considered as women-friendly technologies. Given the focus on reduction in labor burden, this study did not consider other outcomes of CSA such as changes in women’s decision-making authority, changes in women’s control over income, and improved access to agricultural resources. Out of the list in Table 1, we estimated a gender participation index for six prominent CSA technologies adopted in the study areas. These technologies include direct seeded rice without machine use and with machine use, system of rice intensification, zero tillage and direct seed rice, green manuring, and laser land leveling.

Results and discussion

Women in agriculture–poverty–climate risk hotspots

Figure 1 presents hotspots of women in agriculture–poverty and climate risk across Nepal. Twenty-one districts are identified as “hotspots.” Since 2001, the out-migration of economically active male labor from the hotspot districts is relatively high compared to districts falling under the “low” category (GoN 2014). Consequently, women’s participation in agricultural activities in the hilly regions has gradually increased in the recent decade (MoLE 2015). Incidence of drought and floods, changes in rainfall patterns and population dependency on the use of natural resources such as forest and water are also high in the hotspots (NEOC 2015). These districts, therefore, become important areas for prioritizing efforts to promote women-friendly CSA interventions.

Climatic risks and impacts in study areas

We selected Rupandehi and Chitwan districts from the hotspots for a detailed analysis of women in agriculture and climatic risks (Fig. 1). Survey results identified flood, extreme and erratic rainfall, cold waves, and frequent droughts as the major climate change events occurring since 2001 in these areas. Many farmers reported significant crop yield losses (30–70% loss) as a result of these events. Incidence of climatic risks in these two districts, households affected by them, and their negative effects on crop production all increased from 2003 to 2012 (Fig. 2).

Similar to farmers’ experience, the incidence and severity of climatic risks such as flood, droughts, rainfall-induced landslides, and thunderstorms have also increased in the last decade across Nepal (NEOC 2015; Krishnamurthy et al. 2013). Since 2007, the frequency of these extreme weather events has increased significantly, with their occurrence every alternative year. Figure 3 highlights the number of times these events happened across the country during 2000–2014.

Labor gap assessment in agriculture

Figure 4 presents the average days of labor contribution of women and men in the surveyed households. Women’s labor contribution in agriculture is significantly high compared to men’s contribution. The range of total number of days of women’s labor contribution to agricultural activities among the survey household is also large. This high level of women’s involvement in agricultural activities is largely influenced by out-migration of male and/or low off-farm opportunities for women. They work primarily as family workers in subsistence agriculture with low technology-driven conventional farming practices.

Total labor days contribution by men and women

Table 3 clearly differentiated the role of men and women in agriculture. In some activities, such as rice transplanting, weeding, irrigation application in rice, and harvesting/threshing of wheat and maize, women’ labor contributions are significantly high. Land preparation, crop sowing, and fertilizer application, on the other hand, are mainly men’s responsibility. This information builds the case for the promotion of CSA technologies that, for instance, facilitate transplanting of rice, weeding, and harvesting/threshing which can significantly reduce women’s labor contribution in agriculture.

Determinants of women’s participation in agriculture

Table 4 highlights the role of socioeconomic variables in determining women’s participation in agriculture. Women in large landholding and non-agricultural income households contribute less to agricultural activities due to their access to off-farm economic activities and ability to hire labor. On the other hand, increasing family size, agriculture as a main occupation of the household head, and woman household head all act as contributing factors for increased women’s participation in agricultural activities over that of men. Large family size is generally related to poor income level and more females in the household (Maharjan and Khatri-Chettri 2006). Understanding these results can play an important role in better targeting of CSA intervention for women farmers.

Women and CSA technologies

Farmers in the household survey and focus discussions provided a list of agriculture and related activities where women’s involvement is high and highlighted key CSA interventions suitable in each activity along with their expected impacts on labor, income, and yield (Table 5). The roles of these CSA technologies in improving crop yield and farm income while reducing women’s labor burden in agriculture are also well recognized as per literature (Kristjanson et al. 2017; Jost et al. 2016).

Impact of technologies on CSA indicators

Evaluation of some of these CSA interventions highlighted that all selected technologies have significant potential to reduce women’s labor contribution in agricultural activities, particularly in transplanting, nutrient management, and sowing of crops (Fig. 5). Direct seeded rice (zero tillage and low tillage using machine) and green manuring (GM) in particular can significantly reduce women’s labor hours/days in agriculture.

Figure 6 presents impact of technologies on efficiency, equity, gender, environment, and sustainability indicators of CSA. Higher production efficiency over farmers’ practices was observed in DSR methods, LLL, and SRI technologies. This was mainly due to a positive effect of technology in crop productivity. Similarly, for the equity indicator, employment generation and higher calorie production were observed for DSR machine (after plowing), SRI, and LLL.

Impact of CSA technologies on five indicators

In zero-till DSR and GM, no women’s participation was observed whereas a higher proportion of participation of women was observed in farmers’ conventional practice (without CSA technology interventions). Sustainability index was found to be higher in zero-till DSR, indicating higher sustainability than other farming technologies. The environmental index was found to be higher for GM applied in rice fields indicating a higher potential of greenhouse gas emission compared to other technologies. Lowest emission values were calculated for DSR using machine and DSR hand broadcasting, which is much lower than the GHG emission index of GM rice and farmers’ practice (FP).

Conclusions

The study adopts a top–down approach of examining the potential of CSA to reduce women’s labor burden in agriculture in the wake of climate change. A targeted approach using the hotspot methodology can prove to be useful in cases where prioritization of resources is a criterion. This method of hotspot identification and targeting of CSA options is seldom being used by most of the current development-related programs on women and agriculture. National and sub-national government and development organizations also focus on implementation of outcome-oriented strategies which tend to cover a large proportion of the target population, without much streamlining. This study promotes a more focused approach to identify more vulnerable regions (hotspots) related to women in agriculture–poverty–climate risk and promote technologies for reducing labor burdens for women in those regions.

Based on the activities majorly conducted by women, this study shows that CSA technologies and practices such as direct seeded rice, zero tillage machines, laser land leveling, and green manuring can reduce women’s labor burden in agriculture. Other CSA technologies such as crop harvesters, weeder, solar pump irrigation, and post-harvest management practices can also substantially reduce women’s labor burden. However, apart from reduction in labor hours, CSA also has an instrumental role in improving women’s access to agricultural resources and decision-making process as well as provide linkages to new market opportunities. Further studies, therefore, are needed to consider holistic approaches that would evaluate the implications of different CSA interventions on men and women in different socioeconomic settings and roles.
