Location: Asia
As a fast growing region with increasing challenges for smallholder farmers, Asia is a key target region for CIMMYT. CIMMYTâs work stretches from Central Asia to southern China and incorporates system-wide approaches to improve wheat and maize productivity and deliver quality seed to areas with high rates of child malnutrition. Activities involve national and regional local organizations to facilitate greater adoption of new technologies by farmers and benefit from close partnerships with farmer associations and agricultural extension agents.
SPG Coalition: CIMMYT is a leading organization for climate-smart agriculture, nutrient-use efficiency, and pest and fertilizer management
The Coalition on Sustainable Productivity Growth for Food Security and Resource Conservation (SPG Coalition) brings together researchers, non-governmental organizations, and private sector partners to advance a world with greater access to nutritious food and affordable diets. The Coalition recognizes that increasing the productivity of natural resources through climate adaptation and mitigation is instrumental to reaching this goal.
In a recent report, the SPG Coalition provides a path forward for NGOs, research institutions, and government agencies to strengthen agrifood and climate policies. The report contains real-life, evidence-based examples to further the sustainable production and conservation of natural resources, detailing the potential impacts on social, economic, and environmental conditions.
CIMMYT features prominently in the report as a leading organization focused on 4 main areas: climate-smart agriculture, nutrient-use efficiency (NUE), and pest and fertilizer management.
Nutrient-use efficiency and fertilizer management
While chemical fertilizers increase crop yields, excessive or improper use of fertilizers contributes to greenhouse gas emissions (GHG) and increases labor costs for smallholders. Efficient NUE is central to nutrient management and climate change mitigation and adaptation.
In India, CIMMYT, along with the Borlaug Institute for South Asia (BISA), CGIAR Research Centers, and regional partners, tested digital tools like the Nutrient Expert (NE) decision support tool which measures proper fertilizer use for optimized yields and provides nutrient recommendations based on local soil conditions.
The majority of smallholders who applied the NE tool reported higher yields while emitting less GHG emissions by 12-20% in wheat and by around 2.5% in rice as compared with conventional fertilization practices. Farmers also recorded double economic gains: increased yields and reduced fertilizer costs. Wider government scaling of NE could enhance regional food security and mitigate GHG emissions.
The Feed the Future Nepal Seed and Fertilizer (NSAF) project, led by CIMMYT and USAID, advocates for climate-smart agriculture by linking smallholders with improved seed, providing capacity-building programs, and promoting efficient fertilizer use. With a vast network established with the support from the Government of Nepal, NSAF successfully provides smallholders with expanded market access and nutritious and climate-resilient crop varieties.
Climate-smart maize breedingÂ
Since its arrival to sub-Saharan Africa (SSA) in 2016, fall armyworm (FAW) has devastated maize harvests for countless smallholders on the continent. Economic uncertainty caused by unstable yields and climate stressors like drought coupled with this endemic pest risk aggravating food insecurity.
CIMMYT and NARES Partner Institutions in Eastern and Southern Africa are spearheading a robust pest management project to develop, screen, and introduce genetically resistant elite maize hybrids across SSA. South Sudan, Zambia, Kenya, and Malawi have already deployed resistant maize varieties, and eight other countries in the region are projected to release their own in 2023. These countries are also conducting National Performance Trials (NPTs) to increase awareness of host plant resistance for the sustainable control of FAW and to sensitize policymakers on accelerating the delivery of FAW-tolerant maize varieties.
The establishment of FAW screening facilities in Africa permits more rapid detection and breeding of maize varieties with native genetic resistance to FAW, facilitating increased deployment of these varieties across Africa. The sustainable control of FAW demands a rapid-response effort, overseen by research organizations and governments, to further develop and validate genetic resistance to fall armyworms. Achieving greater impact for maize smallholders is critical to ensuring improved income and food security in Africa. It is also paramount for biodiversity conservation and removing labor burden on farmers applying additional synthetic pesticides to prevent further losses by the pest.
âThe SPG Coalition report emphasizes the power of partnership to enhance financial and food security for smallholder communities in the Global South. This is fully in line with the recently launched CIMMYT 2030 strategy. Itâs also an important reminder to assess our strong points and where more investment and collaboration is needed,â said Bram Govaerts, CIMMYT director general.
Climate Adaptation Atlas will support evidence-based solutions in Sri Lanka
We are all aware the immense challenges countries face due to climate change, particularly its impacts on vital sectors like agriculture, forestry and livestock. The agriculture industry is profoundly affected by unpredictable weather patterns and frequent incidences of extreme events such as floods, droughts and landslides. Consequently, finding effective solutions to address these issues becomes of paramount importance. Climate-resilient agriculture necessitates the adoption of sustainable crop and land management technologies.
In the context of South Asia, Sri Lanka stands out as one of the most severely affected countries by the impacts of climate change. The nation contends with a multitude of hazards, ranging from floods and landslides in the western and southwestern regions, drought and pest outbreaks in the northern region and coastal erosion along the coastal belts. These examples underscore the growing complexity and challenges associated with managing climate risks and patterns, especially when multiple hazards occur simultaneously.
In response, Sri Lanka has implemented climate-smart agricultural interventions, including the development and introduction of stress-tolerant crop varieties, rainwater harvesting, the introduction of energy-efficient irrigation systems, implementation of soil and water conservation programs and crop diversification. However, the agricultural sector still faces formidable challenges. There is a lack of up-to-date information on climate change and its impacts, a fragmented institutional setup, overlapping mandates and limited capacity for information sharing. To address these issues, we require zone-based planning and institutional collaboration. Integrating spatial considerations into rehabilitation and development interventions is the main consensus among stakeholders. All ongoing and planned programs need vulnerability information, and there is a consensus among stakeholders on the need to integrate spatial considerations into rehabilitation and development interventions.
This is where the Atlas of Climate Adaptation in South Asian Agriculture (ACASA) project becomes an invaluable asset in expediting Sri Lanka’s journey towards climate-smart agriculture. Recent evidence highlights the need for a comprehensive assessment of location-specific climate actions to bridge knowledge gaps within the country. Through the Atlas, we will quantify localized climatic risks today and, in the future, assess their likely impacts on agriculture and identify key adaptation options to mitigate these risks. This knowledge will strengthen Sri Lanka’s food security and reduce its vulnerability to climate-related hazards. By complementing traditional methods of risk characterization with novel approaches like intensity and frequency analysis of hazards and historical crop yields, our efforts will gain added efficacy.
ACASA, therefore, offers us a unique opportunity to foster collaboration, share knowledge and develop evidence-based innovative solutions to confront the challenges posed by climate change in Sri Lanka. It serves as a platform to connect hazards, practices, tools and adaptation options. By intertwining various aspects of climate change and gaining a deeper understanding of its spatial and temporal dimensions through the Atlas, Sri Lanka is steadfast in its commitment to building resilience and creating a sustainable future for generations to come.

Bangladesh to improve risk characterization at a granular level with Atlas
Bangladesh is one of the most climate-vulnerable countries in the world. The climate risks are negatively impacting the country’s agricultural sector, which constitutes nearly 12% of the countryâs GDP. Additionally, 40% of the countryâs workforce rely on agriculture for a major portion of their income (BBS, 2021-22).
Despite these challenges, Bangladesh has demonstrated remarkable economic growth by strategically investing in climate resilience and disaster preparedness over the years. The country has gained global recognition as a leader in these areas, driving its overall development. However, escalating climate risks continue to pose threats to Bangladesh’s progress, particularly impacting the most vulnerable segments of society and jeopardizing the nation’s growth trajectory.
In response to these challenges, Bangladesh has made concerted efforts to develop climate adaptation strategies. A significant milestone was the launch of the GCA Global Hub on locally led adaptation by the Honorable Prime Minister Sheikh Hasina in 2022. This groundbreaking initiative aims to support one million climate-vulnerable migrants in Bangladesh. The government has also formulated policies, plans and programs to combat the impacts of climate change. The Bangladesh Climate Change Strategy and Action Plan (BCCSAP), formulated in 2009 and updated in 2022, focuses on six thematic areas, with five and six emphasizing adaptation and mitigation, respectively. Another important initiative is the Bangladesh Delta Plan 2100, prepared in 2017, which categorizes the entire country into six hotspots. To safeguard the agricultural sector from climate change, Bangladesh has also developed vulnerability Atlases such as the ‘Bangladesh Climate and Disaster Risk Atlas: Volume 1 & 2’ and the ‘Climate Adaptation Services Bangladesh (Haor region).’
While significant progress has been made in risk mapping, there is room for improvement. For instance, the current Atlases operate at the district level, and there is immense potential to downscale them to the upazila (sub-district) level to achieve enhanced granularity. Additionally, transforming the Atlases from report format to a more interactive and user-friendly online one would be beneficial.
The Atlas of Climate Adaptation in South Asian Agriculture (ACASA) project aligns with the goals of BCCSAP, focusing on location-specific climate change adaptation and mitigation strategies in agricultural production. The Atlas will play a crucial role in quantifying localized climatic risks, assessing their impacts on agriculture today and in the future, and identifying key adaptation options to mitigate these risks. This knowledge will strengthen Bangladesh’s food security and reduce its vulnerability to climatic risks.
The Bangladesh Agricultural Research Council (BARC) will actively utilize the Atlas, leveraging agro-geospatial data to expedite decision-making processes. BARC will further leverage its expertise in geospatial tools, crop zoning information systems, GIS-based mobile apps, climate information databases and drought monitoring systems, further combined with the knowledge base of Atlas to ensure informed and evidence-based actions. Moreover, collaborating with ACASA to develop an advanced and interactive online Atlas expands the country’s scope and fosters stakeholder participation, enabling informed decision-making and refined risk characterization at a granular level.

Adaptation Atlas is a positive step towards climate resilient agriculture
India holds an impressive record in agricultural production. We are among the largest producers of milk, pulses, tea, spices, cashew, jute and bananas. Additionally, we rank as the second-largest producer of wheat, rice, fruits and vegetables. Our agricultural sector has experienced notable growth, with production increasing from 3 to 127 times since the 1970s. We have also witnessed a substantial boost in agricultural productivity, with yields per hectare rising from 0.7 to 2.3 tons during the same period.
Despite these achievements, we face pressing challenges that threaten our agricultural landscape. Water scarcity, soil degradation, pest and disease outbreaks, and the intensifying impacts of climate change need urgent attention.
In India, we observe that minimum temperatures are rising faster than maximum temperatures. We also witness a more pronounced temperature increase during the rabi (winter) season than the kharif (monsoon) season. Rainfall is becoming more variable with increasing episodes of extreme rainfall. These climate risks increase our food and livelihood insecurity.
We need advanced technological interventions and optimized resource allocation to address these challenges. Our development path, “Amrit Kaal,” necessitates climate-friendly practices prioritizing low carbon, water, nitrogen and energy usage. To further realize this vision, adopting 5Ms based on better markets, regional planning for monsoons, improved mechanization, management of micro-irrigation and new fertilizers, and mainstreaming the insurance is pivotal.
India has undertaken research, development and policy initiatives to build resilience in our food production system. However, the growing challenges of climate extremes demand sustained global efforts. The Indian Council of Agricultural Research (ICAR) therefore, welcomes international collaboration to exchange experiences and knowledge in climate action. We believe that collective efforts and shared expertise will strengthen our adaptation strategies.
In this regard, the Atlas of Climate Adaptation in South Asian Agriculture (ACASA) project can play a vital role. ICAR is glad to support ACASA and will deploy a team of young scientists to contribute to and benefit from this Adaptation Atlas. Furthermore, we are pleased to offer our website as a platform to host the Atlas, facilitating its broader utilization within our country. We thank the Borlaug Initiative in South Asia (BISA) and the Bill and Melinda Gates Foundation (BMGF) for initiating this project in India.
Together, let us pave the way toward a climate-resilient future for agriculture, safeguarding our farmers’ livelihoods and securing food for future generations.

Atlas of Climate Adaptation in South Asian Agriculture (ACASA)
About ACASA
Increasing climatic risks make it imperative to identify spatial and temporal risks that are likely to impact agriculture. Adaptation options are thus needed to mitigate the negative impacts. Considering this, with support from the Bill & Melinda Gates Foundation (BMGF), the Borlaug Institute for South Asia (BISA) is working with national agriculture research systems in South Asia to develop the Atlas of Climate Adaptation in South Asian Agriculture (ACASA).
This comprehensive Atlas aims to provide granular-scale information for South Asian countries at the village scale by integrating various spatially explicit data sets together. It covers climate hazards, and the exposure of smallholder populations, farms, and crop and livestock enterprises to hazards. It will also look into the vulnerability of these populations to climatic risks, impacts on critical commodities in the region, and evidence of the effectiveness of different climate adaptation interventions.
The ACASA offers a unique set of tools that can facilitate improved investment targeting and priority setting, and support stakeholders’ decision-making and investments in agricultural technologies, climate information services, and policies. The intended beneficiaries of this Atlas include governments, insurance and agri-food industries, international and national donors, and adaptation-focused entities.

A new Climate Adaptation Atlas to safeguard South Asian agriculture
Climate change is no longer a distant threat but a reality that profoundly affects our lives. Among the most vulnerable regions to climate change, South Asia stands out because it is home to over 100 million farmers and produces over 285 million metric tons of milled rice and 128 million metric tons of wheat (FAO 2020-21). Among 193 countries worldwide, South Asian countries rank in the top quarter for climate risk and are experiencing rising meteorological and climate-related disasters. These pose significant challenges to farmers and the 216 million people in South Asia living in extreme poverty (World Bank, 2018), further jeopardizing their food security and livelihoods.
Considering this, with support from the Bill & Melinda Gates Foundation, the Borlaug Institute for South Asia (BISA) is working with national agriculture research systems in South Asia to develop the Atlas of Climate Adaptation in South Asian Agriculture (ACASA).
The Atlas brings together spatially explicit South Asian data on the nature and evolving patterns of climate hazards. It will assess climate risks using gridded, village-scale analyses and through historical crop yield data and satellite signatures. The Atlas will consider the exposure of smallholder populations, farms and crop and livestock enterprises. It will assess the vulnerability or adaptive capacity of those populations and impacts on the regionâs critical commodities. Importantly, the Atlas will provide a unique set of on-line tools and a portfolio of adaptation options to underpin better decisions regarding investments in agricultural technologies, climate information services, and policies. The project will also focus on building the capacity of concerned stakeholders such as multi-lateral agencies, government bodies, NGOs, and the private sector in the use of Atlas assets, through training materials, tutorials, and periodic workshops. This will enable informed investments and policy decisions to benefit 100 million farmers in South Asian region. For wider use, the Atlas will be embedded online as an open-source, web-enabled and interactive and dynamic tool for easy access by all concerned stakeholders.
Drawing on the expertise and experience of South Asian nations such as Bangladesh, India, Nepal, and Sri Lanka, which have suffered from extreme heat, prolonged droughts, and severe flooding in key crop-producing areas, ACASA represents an example of collaboration and knowledge exchange to reduce farmers’ risks and offer them ways to adapt.
BISA and CIMMYT are pleased to anchor this remarkable collaboration that leverages multi-disciplinary expertise and perspectives to address the complex challenges posed by climate change, linking the detailed characterization of climatic risks with mitigation technologies and policies to meet the needs of diverse stakeholders. The proposed work will contribute actively to the CIMMYT2030 Strategy where one of the 5 impact areas is centered around Climate adaptation and Mitigation. The entire strategy designs a path toward a Food and Nutrition Secure world through science and innovation in the midst of a global climate crisis.
Established in 2011 by CIMMYT and the Indian Council of Agricultural Research (ICAR), the Borlaug Institute for South Asia (BISA) is a non-profit international organization that applies advanced technologies to improve food systems and food security, nutrition, livelihoods, and the environment in South Asia, home to more than 300 million undernourished people.
Hard work pays off
Nepal is an agricultural country, where the sector provides the major source of income for half the population. Despite this, the sad reality is that the country is not able to produce enough crops to meet its needs, and major grains like rice, maize, and cereals are mostly imported.
One factor influencing this is an aging population of farmers, alongside decreasing interest in agriculture among the countryâs youth. Many young people do not see agriculture as a viable option for employment, opting instead for work opportunities outside the country. However, there are still some youth who see agriculture as a profitable business, like Pradeep Morya.
âIt is better to work hard in your home country rather than going abroad and working tirelessly every minute and hour,â says Morya, a 24-year-old farmer from Banke, Nepal, who finds happiness in living close to his family and helping to support national food security. âI love being in the field,â he explains. âI have cultivated spring maize on one hectare. My day-to-day business is to provide care to the spring maize along with pumpkins and beans that I have added for additional income on a small plot of land.â
Working alongside his eldest brother, Morya has cultivated 30 kattha of land (equivalent to 0.36 hectares) using the spring maize varieties Pioneer 1899 and DK 9108. His brother, a member of Mahatarkari cooperative in Duduwa, western Nepal, has been providing him with the knowledge and expertise needed for maize cultivation.
Mahatarkari is one among 50 cooperatives working in partnership with the Nepal Seed and Fertilizer project (NSAF), which is implemented by CIMMYT. NSAF works with the cooperatives to provide technical knowledge and training to farmers, to hone their potential and support them in the adoption of modern technologies which can improve their livelihoods. After participating in programs organized by NSAF, Morya makes sure that the suggestions he receives â on soil preparation, weed management, harvesting, and more â are implemented in his field.
Returning to the family farm
A few years back, the situation was different. Like many youths in the country, Morya also went abroad to try his luck on the international job market. He worked hard for two years in Malaysia but was forced to return to Nepal during the COVID-19 pandemic.
âI had imagined my shining future abroad. However, when I reached there, the reality was different,â recalls Morya. âI returned to my own country just before the lockdown in April 2021 with some small savings. Upon my arrival in Nepal, I was clueless about my future. I dropped my education after grade five. With no educational qualifications and skills in hand, it was difficult to get a decent job.â
Since the country was in lockdown, Morya chose to stay at home and support his family on the farm. It was here that his eldest brother guided him into farming, and Morya soon learned the knowledge needed to run the farm and began earning money from it. This attracted him towards farming as a longer-term career option, and he has now discovered a prosperous future in agriculture.
âAgriculture needs continuous effort,â he says. âWith the support of technology, it is easy and efficient to work. I work every day so that I can reap crops on a large scale to make a profit. I manage weeds, irrigation, and control pests.â
âI also have livestock. I get adequate fodder for my cows and buffalo from weeds and from the spring maize. I sell milk in the market. In addition to this, I also make sure to produce off-season vegetables so that I receive a decent price for additional income.â With the support of his family, Morya has recently purchased an e-rickshaw, which he uses to transport and sell his produce.
To further support his endeavors, Morya has also been participating in Nepalâs Maize Commercialization Network and using the Geo Krishi mobile app to learn about current market prices. âBefore knowing about the commercialization of crops, it was hard to receive good amounts from buyers,â he explains. âNow, I make a call to the local retailers and buyers to learn the best value of my grain. Sometimes I also explore the market. Then, I analyze the rate and sell my maize.â He uses a similar system for his off-season vegetables, selling either in the local market or directly to consumers for a premium price. âI make a saving of around 1500 Nepalese rupees (approximately US$ 11) per day,â he says.
A prosperous life
With the profits from his agricultural business, Morya has been able to fulfill his dream of purchasing a bike, as well as contributing to the construction of a new eight-room house, where his family is now living comfortably. âI love to roam on my bike with my friends in the evening. I also take my mother for a ride,â says Morya with a bright smile. âNow, I have a dream to live a prosperous life with my family.â
Thanks to the support provided by the NSAF project with generous funding from USAID, young people like Morya can pursue a better life for themselves and their families. Agricultural training programs have not only helped young people fulfill their basic needs, but also to achieve their dreams. It is hoped that ongoing efforts to empower farmers through science and innovation will continue helping young farmers like Morya break the chain of unemployment, for both their own benefit and that of Nepal.
CIMMYT releases 32 new elite maize lines
CIMMYT is pleased to announce the release of a set of 32 new CIMMYT maize lines (CMLs). These maize lines have been developed by CIMMYTâs Global Maize Program by a multi-disciplinary team of scientists in sub-Saharan Africa, Latin America, and Asia. The lines have diverse trait combinations and are suitable for the tropical/subtropical maize production environments targeted by CIMMYT and partner institutions.
CMLs are freely available to both public and private sector breeders worldwide under the standard material transfer agreement (SMTA).
CIMMYT seeks to develop improved maize inbred lines for different product profiles, with superior yield performance, multiple stress tolerance, and enhanced nutritional quality. CMLs are released after intensive evaluation in hybrid combinations under various abiotic and biotic stresses, besides optimum (non-stress) conditions in the target population of environments. Suitability as either female (seed) or male (pollen) parent is also evaluated. As done in the last announcement of CMLs in 2021, to increase the utilization of the CMLs in the maize breeding programs of the partner institutions, all the new CMLs are tested for their heterotic behavior and assigned to specific heterotic groups of CIMMYT: A and B.
The release of a CML does not guarantee high combining ability or per se performance in all the environments; rather, it indicates that the line is promising or useful as a parent for pedigree breeding or as a potential parent of hybrid combinations for specific mega-environments. The description of the lines includes heterotic group classification, along with information on their specific strengths and their general combining ability with some of the widely used CMLs or CIMMYT coded lines under different environments.
More information:
Summary of the characteristics: CIMMYT maize lines CML616A to CML647A (PDF)

Government of Nepal adopts new fertilizer recommendations
Balancing the application of fertilizers based on the characteristics of soil leads to increased crop productivity, income, and fertilizer use efficiency unlike former âone size fits allâ recommendations, said Bedu Ram Bhushal, Nepalâs Minister of Agriculture and Livestock Development (MoALD) during a press briefing earlier this month in Nepalâs capital Kathmandu.
The site-specific recommendations applicable to maize, wheat, and rice were jointly launched with the Nepal Agricultural Research Council (NARC) and National Soil Science Research Center (NSSRC). They were implemented in collaboration with the Department of Agriculture (DoA) and led by the Nepal Seed and Fertilizer (NSAF) Project at the International Maize and Wheat Improvement Center (CIMMYT).
âI congratulate NARC for this historical work on updating the fertilizer recommendations after 46 years,â Bhushal said. âNow, we should support the large-scale adoption of these new recommendations by farmers for sustainable soil fertility management.â
Earlier recommendations developed by the Agricultural Chemistry and Soil Science Service Section under the Department of Agriculture (DoA) in 1976 did not take into account soil diversity, biophysical conditions, and agronomic management. Nutrients recommended for a particular crop were the same for terai lowlands, hills, and mountains.
In general, soil fertility changes over time due to deployment of continuous intensive cropping systems. The new recommendations consider the indigenous nutrient supply of soils, target yields, and the amount of nutrients removed by crops at harvest.
It took six years for NSSRC of NARC in partnership with NSAF, to update the recommendations through nutrient omission and optimum nutrient rate trials in various locations. By using advanced analytical methods and machine learning tools for extrapolating data across different agroecological zones and domains, they were able to make them site-specific.
Other factors considered, included attainable yield at a particular farm, soil fertility status, agro-climate, crop management practices, and the amount of nutrients to be supplied to fill the gap between crop nutrient removal and soil nutrient supply of nitrogen, phosphorus, and potassium. Micronutrients and organic inputs were also considered.
These recommendations were presented to leading soil scientists and agronomists from NARC and MoALD and were validated at national meetings in July and October 2022.
The new recommendations were included in the DoAâs agriculture extension guidelines in 2023, to achieve potential yield at the farm level and to link with the extension system through the three-tier of governments for its extensive use throughout the country. The new approach is part of CIMMYTâs efforts to support the NARC, MoALD, provincial agriculture ministries, and farmers to build indigenous soil fertility management resources and capabilities and promote locally adapted strategies for long-term resilience by using integrated soil fertility management approaches.
Whatâs the link between two-wheel tractors and elephants?
CIMMYT principal scientist Frédéric Baudron has two main research interests: making mechanization appropriate to smallholders and biodiversity conservation.
Wondering how these two intersect, a colleague of Baudron once asked him what the link was between an elephant and a tractor?
Now, in the recent report, âAddressing agricultural labour issues is key to biodiversity-smart farming research,â published in Biological Conservation, Baudron and other contributors have answered that question, examining trade-offs between labor and biodiversity conceptually, as well as in the specific context of Indonesia and Ethiopia.
This research continues work CIMMYT has done on the relationship between agriculture and biodiversity, including Commodity crops in biodiversity-rich production landscapes: Friends or foes? The example of cotton in the Mid Zambezi Valley, Zimbabwe and Sparing or sharing land? Views from agricultural scientists
Innovations in agricultural technology have led to undeniable achievements in reducing the physical labor needed to extract food from fields. Farm mechanization and technologies such as herbicides have increased productivity, but also became on the other hand major threats to biological diversity.
Adopting technologies that improve the productivity of labor benefits farmers in multiple ways, including a reduction of economic poverty, time poverty (i.e., lack of discretionary time, reducing labor drudgery), and child labor. Conversely, technologies that promote biodiversity often increase the burden of labor, leading to limited adoption by farmers. Therefore, there is a need to develop biodiversity-smart agricultural development strategies, which address biodiversity conservation goals and socio-economic goals, specifically raising land and labor productivity. This is especially true in the Global South, where population growth is rapid and much of the worldâs remaining biodiversity is located.
âWithout accounting for labor issues biodiversity conservation efforts will not be successful or sustainable,â said Baudron. âBecause of this, we wanted to examine what biodiversity-smart agriculture might look like from a labor point of view.â
Research has quantified that farming families in Africa who use tractors expended an average of 640 labor hours per hectare in maize cultivation. In contrast, farmers not using tractors spent over 1100 hours for the same yield.
Trade-offs
While that is a clear win for reducing the heavy physical toil of farming, there are potential negative effects on biodiversity. In many countries in the Global North, the rise of tractors and other big machinery has led to larger and more rectangular fields and the removal of farm trees and hedgerows, all of which is associated with lower biodiversity. The same is now happening in parts of the Global South.
âA trade-off implies that one goal can only be achieved at the expense of another goal,â said Baudron. âIt is not always a conscious choice; however, as farmers often adopt labor-saving techniques without considering the effects on biodiversity, simply because they lack options, and sometimes the necessary context.â
In Indonesia, the transition from harvesting rubber to producing palm oil has reduced the amount of physical labor, but biological diversity has decreased. However, innovations such as reducing fertilizer usage to avoid nutrient leaching into soil have been possible without compromising yield, and with the benefit of lower costs to farmers.
In Ethiopia, labor-saving technologies like the use of small-scale combine harvesters have been compatible with high biodiversity.
âI tell my colleagues a two-wheel tractor that allows mechanization with little negative environmental consequence (compatible with a mosaic of small, fragmented fields, with on-farm scattered trees, etc.) contributes to a landscape that works for people and biodiversity, including elephants,â said Baudron.
