(Book Chapter, 2023-01) Clerck, Fabrice A.J. de; Koziell, Izabella; Benton, Tim; Garibaldi, Lucas A.; Kremen, Claire; Maron, Martine; Rumbaitis del Rio, Cristina; Sidhu, Aman; Wirths, Jonathan; Clark, Michael; Dickens, Chris; Estrada-Carmona, Natalia; Fremier, Alexander K.; Jones, Sarah K.; Khoury, Colin K.; Lal, Rattan; Obersteiner, Michael; Remans, Roseline; Rusch, Adrien; Schulte, Lisa A.; Simmonds, Jeremy; Stringer, Lindsay C.; Weber, Christopher; Winowiecki, Leigh Ann
Toward structural change: Gender transformative approaches
(Book Chapter, 2021-11) McDougall, Cynthia; Badstue, Lone B.; Mulema, Annet A.; Fischer, Gundula; Najjar, Dina; Pyburn, Rhiannon; Elias, Marlène; Joshi, Deepa; Vos, Andrea
Almost a quarter of a century after the Beijing Declaration, and with 10 years left to meet the Sustainable Development Goals, The Guardian announced the SDG Gender Index’s finding that, “Not one single country is set to achieve gender equality by 2030” (Equal Measures 2030 2019, Ford 2019). This aligns with the most recent Global Gender Gap Index, which signals that, on the current trajectory, it will take approximately 170 years to achieve gender equality (WEF 2016)—a wait of seven generations, or two and a half lifetimes for the average woman.
A gender-natural resources tango: Water, land, and forest research
(Book Chapter, 2021-11) Joshi, Deepa; Monterroso, Iliana; Gallant, Bryce; Perera, Kokila; Peveri, Valentina
Gender relations shape identities, norms, rules, and responsibilities for women and men, and mediate access to, use, and management of water resources, as well as ownership, tenure, and user rights to land and forests (and related infrastructure, services, technologies innovations and interventions). Natural resource management (NRM) interventions thus have important implications for women’s labor, time, decision-making, and transformational gains.

Governance of woodfuel value chains in Kenya: An analysis of policies, legislative frameworks and institutional mechanism
(Working Paper, 2020-12-28) Sola, P.; Bourne, M.; Okeyo, I.; Njenga, M.
Successful woodfuel value chain governance is dependent on the existence of known policies that are implemented, rules and regulations that are enforced and complied with by value chain actors and institutions with capacity to regulate and render support. Kenya has formulated policies nd enacted legislation for guiding, managing and supporting woodfuel value chains. These policies and legal frameworks have evolved over the years, integrating provisions for sustainable production, distribution and use of woodfuel. However, even with well-developed policies and legislative frameworks, charcoal value chains are inadequately governed, beset by illegality, weak institutional arrangements, overlapping mandates and limited coordination and cooperation. Nonetheless, charcoal value chains have remained resilient despite the bans and moratoria throughout the decades and likely to continue in the foreseeable future. Limited knowledge, lack of incentives for sustainable production and limited support for organized efforts to manage woodfuel resources are contributing to low compliance with rules and regulations. Therefore, the development and implementation of interventions coupled with appropriate investments to incentivize and catalyze sustainable woodfuel production and trade cannot be over emphasized.

Unlocking maize crop productivity through improved management practices in Northern Tanzania
(Journal Article, 2020) Kihara, Job Maguta; Kizito, Fred; Jumbo, M.; Kinyua, M.; Bekunda, Mateete A.
Addressing the problem of low crop productivity and food insecurity can be accelerated through community-centered implementation of good agricultural management practices. This study was conducted in Babati, Northern Tanzania. The objective of the study was to determine nitrogen (N)and phosphorus (P)application requirements for maize,and demonstrate economically viable best bet yield-improving management technologiesunder three ecozones namely; ‘low elevation low rainfall’, ‘medium elevation high rainfall’ and ‘medium elevation low rainfall’ ecozone. Two sets of trials were conducted: N (0, 45, 90, 120 and 150 kg ha-1) and P (0, 15, 30, 40 kg ha-1) response trials in 16 representative fields in three seasons of 2013/14, 2014/205 and 2015/16 and; demonstrations trials in 8 farmer-selected fields in 2015/16 season. Combined N and P application increased maize yields by 32 to 62% over single nutrient applications.In the medium elevation low rainfall ecozone, 60-86%yield response to nitrogenwas observed.Largely, modest applications of 50 kg N ha-1and 20 kg P ha-1resultedin profitable (marginal rate of return (MRR) of 2.4 to 3.0) yield increases of upto 214% over the farmers practice (unfertilized), varying with variety and ecozone. The source of P (DAP or Minjingu Mazao) had little influence on maize productivity except under low altitude low rainfall where Minjingu Mazao is unprofitable. Farmer rankings and agronomic indices showed new maize hybrids namely Meru H513, Meru H515, and SC627 as a priority across the ecozones; Mams H913 is suitable mainly in medium elevation low rainfall ecozone. The conclusion is that the use of new maize hybrids and appropriate rates of locally available N and P nutrient sources can bridge existing yield gaps and reduce food insecurity. Technologies from community-driven research in development are easily adopted by a large number of farmers and could result in quick, yet lasting productivity gains.

Concept and rationale of evolutionary plant breeding and its status in Nepal
(Journal Article, 2020-09) Joshi, Bal Krishna; Ayer, D. K.; Gauchan, Devendra; Jarvis, Devra I.
Nepal has released and registered a total of 623 genetically uniform (mono genotyped) varieties. These varieties were developed by both conventional and classical plant breeding, biotech-assisted plant breeding, and participatory plant breeding methods. However, these varieties have been shown to vary in their yield performance over the years and locations. Smallholder farmers dominate agriculture with 53% of the land-owning households with their land holding size of less than 0.5 ha in Nepal. Farmers are increasingly losing their own saved seeds. There have been impacts of weather variability, often modern crop varieties are not available to suit with these changing conditions. Farmers are looking for crop varieties that can better adapt to these changing conditions, and seeds of which can be saved for the next season planting. Evolutionary Plant Breeding (EPB), which creates and maintains a high degree of genetic diversity (i.e. polymorphic population), is a choice for breeders and farmers for accelerating the development of climate resilient and sustainably high-performance crop varieties. In 2015, the National Gene Bank in Nepal started an EPB program for the local rice variety, Jumli Marshi with the objective of enhancing genetic conservation through creating a dynamic gene pool. An evolutionary population can be compared to a living gene bank, not only in line with bringing greater yield stability, but also greater diversity in aroma, nutritional value and quality. Evolutionary populations have the potential to produce higher yields and perform better than their local or improved counterparts in adverse, or stress conditions. Under stress conditions, evolutionary populations have also been shown to be more resistant to weeds, diseases and pests damage than homogenous crop populations. Based on the source of diversity used in EPB, two different types of populations- Composite Cross population, and Composite Mixtures, population are developed. With the exception of Europe, and only for some crops, existing seed policies do not favor such populations. Therefore, there is a need to revise seed regulations in order to allow the cultivation of a higher degree of genetic diversity.
Benefit cost analysis of adoption of small farm machineries for rice cultivation in Nepal
(Journal Article, 2020) Acharya, Prakash; Regmi, Punya Prasad; Gauchan, Devendra; Bahadur, Dilli; Bahadur, Gopal
A study was conducted in Jhapa, Sunsari and Bardiya district of Nepal to assess the benefit cost (BCA) analysis of small farm machineries (transplanter, reaper and power tiller) used for rice cultivation. Out of total respondents of 274 under mechanized farm category selected using Raosoft Software of sample size determination, 74% (20) reaper owner, 67% (20) power tiller owner and 100%(09) transplanter owner were selected for benefit cost analysis using simple random sampling. Analysis showed that benefit-cost ratio of reaper and power tiller was higher than (2.89) than transplanter (1.61). The investment on reaper and power appeared to be profitable because of their higher Benefit Cost ratio and internal rate of return, and lower payback period. The results of sensitivity analysis showed that investments in reaper and power tiller would be profitable even if decrease in benefit or increase in costis by 20%. However, in case of transplanter, the internal rate of return would be less than the discount rate when benefit decreases by 20% and cost increases by 20%. Due to high investment at the initial stage, the payback period was longer and IRR was also less than 30% per annum in transplanter, which indicated that investment would not be made for transplanter unless price of transplanter is lowered through regulation of price and provision of subsidy. It is suggested to motivate farmers for adoption of small farm machineries in rice cultivation through provision of differentiated rates of subsidy and technical capacity build up.
Comparative study on technical efficiency of mechanized and traditional rice farm in Nepal
(Journal Article, 2020) Acharya, Prakash; Regmi, Punya Prasad; Gauchan, Devendra; Bahadur, Dilli; Bahadur, Gopal
The study was conducted among 274 mechanized and 220 traditional rice farms using multistage sampling technique to assess the technical efficiency in rice production among mechanized and traditional farmers in Jhapa, Sunsari and Bardiya districts. The Cobb-Douglas functional form of the stochastic production frontier was employed to obtain the technical efficiency in mechanized and traditional rice farms. The overall technical efficiency of the mechanized and traditional rice farm ranged from 40.31 to 92.23 and 31.21 to 85.02%t with the mean technical efficiency of 80.56 and 70.11% respectively. The scope of increasing output by adopting the technology adopted by the best performer was 19.44% in mechanized and 29.89% in traditional rice farm respectively. Majority of the farmers were operating at an efficiency level 70-80% and 60-70% in mechanized and traditional farms respectively. The average technical efficiency of mechanized rice farm was higher than that of traditional rice farm and the difference was significant. There was scope of increasing output through rational use of existing resources in both farm categories. Manures, chemical fertilizers had significant and positive effect to total yield of rice kg/ha. The effect of machine use to total yield of rice was positive and significant. Rice farms adopting machines were more technically efficient compared to traditional rice farm.
Germplasm rescue and rebuilding local seed systems in red zone areas
(Journal Article, 2020) Joshi, Bal Krishna; Gauchan, Devendra; Sapkota, Shreejana; Poudyal, Kritesh; Ghimire, Krishna Hari; Dongol, Durga Man Singh
Native agrobiodiversity become endangered and even lost due to natural disasters in red zone area such as earthquake that hit Nepal on April and May 2015. Endangered agricultural genetic resources should be rescued and revival of disrupted local seed system was essential for sustainable and productive agriculture in earthquake affected areas. The objectives of this paper are to document methods employed to rescue germplasm and rebuild local seed systems in earthquake affected areas to restore lost crop diversity and strengthen local seed systems. Among 14 severely hit districts by April 2015 earthquake in Nepal, 10 districts were selected for germplasm rescue and rebuilding local seed system. We surveyed households and sensitized relevant stakeholders. Earthquake affected areas were declared as red zones and status of crop landraces were assessed through survey, five cell analysis and focus group discussion. Three germplasm rescue techniques, namely direct rescue, diversity fair and indirect rescue were applied. Local seed systems were rebuilt through diversity fair, diversity block, seed exchange, repatriation and diversity kits. Collected accessions were characterized, multiplied and conserved in National Genebank and community seed banks. About 5-10% of total local crop diversity (based on the landraces) were lost due to earthquake in these districts. A total of 921 accessions of 61 crops along with 284 rare and endangered crop landraces were collected and rescued from 35 VDCs of 10 severely earthquake affected districts. Climate analogue sites and climate smart germplasm were identified for some of earthquake affected areas, and five landraces of four crops were repatriated. Participatory seed exchange, diversity fairs and 200 diversity kits (containing 3 to 5 varieties) were employed to revive the local seed systems. Farmers’ preferred landraces were conserved in Community Seed Bank in Lamjung and Dolakha and all collections were conserved in Naional Genebank, Khumaltar, Nepal. The study concludes that multiple approaches and tools are necessary for germplasm rescue and rebuilding local seed systems from red zone area
Are smallholder farmers credit constrained? evidence on demand and supply constraints of credit in Ethiopia and Tanzania
(Working Paper, 2020-11-01) Balana, Bedru; Mekonnen, Dawit Kelemework; Haile, B.; Hagos, Fitsum; Yimam, S.; Ringler, Claudia
Credit constraint is considered by many as one of the key barriers to adoption of modern agricultural technologies, such as chemical fertilizer, improved seeds, and irrigation technologies, among smallholders. Past research and much policy discourse associates agricultural credit constraints with supply-side factors, such as limited access to credit sources or high costs of borrowing. However, demand-side factors, such as risk-aversion and financial illiteracy among borrowers, as well as high transaction costs, can also play important roles in credit-rationing for smallholders. Using primary survey data from Ethiopia and Tanzania, this study examines the nature of credit constraints facing smallholders and the factors that affect credit constraints. In addition, we assess whether credit constraints are gender-differentiated. Results show that demand-side credit constraints are at least as important as supply-side factors in both countries. Women are more likely to be credit constrained (from both the supply and demand sides) than men. Based on these findings, we suggest that policies should focus on addressing both supply- and demand-side credit constraints, including through targeted interventions to reduce risk, such as crop insurance and gender-sensitive policies to improve women’s access to credit.

Guideline for agronomy and soil fertility data collection in Ethiopia: National standard
(Book, 2020) Abera, Dejene; Liben, Feyera M.; Shimbir, Tesfaye; Balemi, Tesfaye; Erkossa, Teklu; Demiss, Mulugeta; Tamene, Lulseged D.
Recently, recognition has been growing of the power of data and information for better decisionmaking and service provision in agriculture. To ensure good data quality, an agreed standard to collect, store, and share data along the agricultural value chain is required. With this background, the purpose of this guideline is to provide guidance on standardizing soil and agronomy data collection and thereby enhance temporal and spatial data interoperability. Standard field research design, data collection, and data reporting are required for well-informed meta-analyses and syntheses of agricultural research data as well as for making these data more accessible for calibration and evaluation of process-based models. Hence, this guideline is a contribution toward enabling meta-analysis of different data collected over years and/or space to accumulate evidence and generate new knowledge or insights to facilitate informed decision-making in the agricultural sector in general and in the crop development subsector. This guideline is compiled and intended for use by researchers, academicians, students, and other interested professionals in Ethiopia and beyond. The guideline is developed based on accepted standards and procedures in the field. Nevertheless, it is not exhaustive in its coverage of the soil and agronomic data types and crops grown in the country. Hence, additions and updates depending on the development of research facilities, the ever-changing focus of agricultural research and production systems, and advances in technology are warranted.

Maintaining diversity of integrated rice and fish production confers adaptability of food systems to global change
(Journal Article, 2020-11-09) Freed, S.; Barman, B.; Dubois, Mark J.; Flor, R. J.; Funge-Smith, S.; Gregory, R.; Hadi, B. A. R.; Halwart, M.; Haque, M.; Jagadish, S.V. Krishna; Joffre, Olivier M.; Karim, M.; Kura, Y.; McCartney, Matthew P.; Mondal, M.; Nguyen, V. K.; Sinclair, Fergus L.; Stuart, A. M.; Tezzo, X.; Yadav, S.; Cohen, Philippa J.
Rice and fish are preferred foods, critical for healthy and nutritious diets, and provide the foundations of local and national economies across Asia. Although transformations, or “revolutions,” in agriculture and aquaculture over the past half-century have primarily relied upon intensified monoculture to increase rice and fish production, agroecological approaches that support biodiversity and utilize natural processes are particularly relevant for achieving a transformation toward food systems with more inclusive, nutrition-sensitive, and ecologically sound outcomes. Rice and fish production are frequently integrated within the same physical, temporal, and social spaces, with substantial variation amongst the types of production practice and their extent. In Cambodia, rice field fisheries that strongly rely upon natural processes persist in up to 80% of rice farmland, whereas more input and infrastructure dependent rice-shrimp culture is expanding within the rice farmland of Vietnam. We demonstrate how a diverse suite of integrated production practices contribute to sustainable and nutrition-sensitive food systems policy, research, and practice. We first develop a typology of integrated production practices illustrating the nature and degree of: (a) fish stocking, (b) water management, (c) use of synthetic inputs, and (d) institutions that control access to fish. Second, we summarize recent research and innovations that have improved the performance of each type of practice. Third, we synthesize data on the prevalence, outcomes, and trajectories of these practices in four South and Southeast Asian countries that rely heavily on fish and rice for food and nutrition security. Focusing on changes since the food systems transformation brought about by the Green Revolution, we illustrate how integrated production practices continue to serve a variety of objectives to varying degrees: food and nutrition security, rural livelihood diversification and income improvement, and biodiversity conservation. Five shifts to support contemporary food system transformations [i.e., disaggregating (1) production practices and (2) objectives, (3) utilizing diverse metrics, (4) valuing emergent, place-based innovation, (5) building adaptive capacity] would accelerate progress toward Sustainable Development Goal 2, specifically through ensuring ecosystem maintenance, sustainable food production, and resilient agricultural practices with the capacity to adapt to global change.
Hacia una cadena de palma aceitera, que contribuya a la conservación de bosques y reducción de gases de efecto invernadero en la región Ucayali
(Report, 2020-08) Ivanova, Yovita; Tristán Febres, María Claudia; Romero Sánchez, Miguel Antonio; Charry, Andrés; Lema, Sebastián; Choy, José Sánchez; Vélez Betancourt, Andrés Felipe; Castro Nuñez, Augusto; Quintero, Marcela
El informe “Hacia una cadena de palma aceitera que contribuya a la conservación de bosques y la reducción de emisiones de gases de efecto invernadero: Estado actual, oportunidades con enfoque de cadena de valor y plan de acción” presenta un insumo para el desarrollo de una cadena de palma aceitera ambientalmente sostenible en la región Ucayali. El documento ha sido realizado bajo el marco del proyecto Sustainable Amazon Businesses (SAB), liderado por el CIAT como parte de la Alianza de Bioversity International y CIAT, en coordinación con MINAM y el MINAGRI del Perú, y en alianza con la consultora internacional Climate Focus (CF). Este proyecto hace parte de la Iniciativa Internacional del Clima (IKI), apoyada por el Ministerio Federal para el Ambiente, la Conservación de la Naturaleza y la Seguridad Nuclear de Alemania (BMU). El presente plan tiene el propósito de contribuir al esfuerzo del Gobierno Regional de Ucayali (GOREU) a reducir las emisiones de gases de efecto invernadero (GEI) del sector agricultura, por el cambio de uso del suelo en la Amazonía peruana, de acuerdo con los compromisos internacionales del Gobierno Peruano para la mitigación del cambio climático. El documento presenta un innovador y novedoso plan para contribuir a la sostenibilidad ambiental de la cadena de valor de palma aceitera, elaborada desde la perspectiva de la conservación de los bosques y la recuperación de ecosistemas degradados y con soluciones aportadas por los actores de la cadena de valor. El plan contribuye a los esfuerzos del Gobierno Peruano de cumplir con las Contribuciones Nacionalmente Determinadas (CND) asumidas en la Conferencia de los Partes - COP21 y el acuerdo entre los Gobiernos de Noruega, Alemania y Perú – Declaración Conjunta de Intención (DCI) – dos compromisos que buscan la reducción de GEI. Asimismo, se busca favorecer la elaboración de planes, políticas y programas nacionales con vistas a lograr los Objetivos de Desarrollo Sostenible (ODS) y la Agenda 2030, donde se reconoce que la agricultura y el cambio climático no pueden considerarse por separado, por lo tanto, se hace necesario un enfoque coherente e integrado de la sostenibilidad en los sectores de agricultura y de ambiente. El presente informe proporciona información de la cadena de palma aceitera lo más actualizada posible, y de gran utilidad para el gobierno nacional y regional, la industria, los productores, las organizaciones no gubernamentales y entidades de cooperación internacional, que actualmente trabajan por una cadena que contribuya al desarrollo sostenible de la agricultura en la Amazonía peruana. Para el desarrollo de este documento diseñado y acordado con los actores claves del sector, el proyecto ha firmado un convenio marco de cooperación con el Gobierno Regional de Ucayali (GOREU). A través de esta cooperación, se ha verificado la articulación de este documento con los instrumentos de desarrollo y ordenamiento territorial y productivos más relevantes de la región. Además, se espera que los elementos específicos de este documento contribuyan al alcance de los objetivos trazados en los principales instrumentos de gestión de la región de Ucayali y del cambio climático en el país, entre otros: el Plan de Desarrollo Regional Concertado (PDRC), la Estrategia Regional de Cambio Climático (ERCC) y la Estrategia de Desarrollo Rural Bajo en Emisiones (ERBE). En este sentido, a partir de este informe, el proyecto SAB pretende acompañar el diseño e implementación de un piloto de modelo de negocio en la cadena de palma aceitera, que materialice varios de los elementos de este informe, donde, a su vez, se aproveche las oportunidades emergentes financieras y de mercado para los productos libres de deforestación y bajos en emisiones de GEI. Se espera que este modelo de negocio y su conversión posterior en un modelo de inversión puedan servir para su replicación y escalamiento en la región y en el país; así mismo, contribuya con los referentes de modelos de negocio libres de deforestación a nivel internacional. Además, se espera que estos modelos sirvan como base para la generación de políticas públicas que aporten a la sostenibilidad del sector.
Carbon storage potential of silvopastoral systems of Colombia
(Journal Article, 2020-09-02) Aynekulu, Ermias; Suber, M.; Noordwijk, M. van; Arango, Jacobo; Roshetko, J.M.; Rosenstock, Todd S.
Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands. Between 2000 and 2017, tree cover across all Colombian grasslands increased from 15% to 18%, with total biomass carbon (TBC) stocks increasing from 0.41 to 0.48 Pg. The range in 2017 carbon stock values in grasslands based on ecofloristic zones (5 to 122 Mg ha−1) suggests a potential for further increase. Increasing all carbon stocks to the current median and 75th percentile levels for the respective eco-floristic zone would increase TBC stocks by about 0.06 and 0.15 Pg, respectively. Incorporated into national C accounting, such Tier 2 estimates can set realistic targets for silvopastoral systems in nationally determined contributions (NDCs) and nationally appropriate mitigation actions (NAMAs) implementation plans in Colombia and other Latin American countries with similar contexts.
