*Global CA-CoP* *CONSERVATION AGRICULTURE COMMUNITY OF* *for sustainable agriculture, land use and ecosystem management* Dear Subscribers, Please see herebelow the May 2022 CA Scoopit newsletter from Cornell. Thank you Professor Hobbs for sharing. *Amir Kassam * *Moderator* *Global CA-CoP* e-mail: [log in to unmask] URL: http://www.fao.org/conservation-agriculture URL: http://www.act-africa.org/ URL: https://ecaf.org/ URL: http://www.caa-ap.org/ *Conservation Agriculture (CA) is an ecological approach to regenerative sustainable agriculture and ecosystem management based on the practical application of context-specific and locally adapted three interlinked principles of: (i) Continuous no or minimum mechanical soil disturbance (no-till seeding/planting and weeding, and minimum soil disturbance with all other farm operations including harvesting); (ii) permanent maintenance of soil mulch cover (crop biomass, stubble and cover crops); and (iii) diversification of cropping system (economically, environmentally and socially adapted rotations and/or sequences and/or associations involving annuals and/or perennials, including legumes and cover crops).* *These practices are complemented with other complementary good agricultural production and land management practices to generate and sustain optimum performance.* *CA systems are present in all continents, involving rainfed and irrigated systems including annual cropland systems, perennial systems, orchards and plantation systems, agroforestry systems, crop-livestock systems, pasture and rangeland systems, organic production systems and rice-based systems. CA systems operate regeneratively at multiple levels to optimally harness a range of productivity, economic, environmental, and social benefits as well as address local and global concerns related to food and water security, climate change, land degradation, biodiversity and smallholder agricultural development.* *Conservation Tillage, Reduced Tillage, Low tillage and Minimum Tillage are not CA, and nor is No-Till on its own. For a practice or a method to be referred to as a CA practice or method, it must be part of a CA system. If not, then it is what it is, a practice or a method similar to any other with its own* *name e.g., no-till seeding, or mulching, or crop diversification, etc. There is no such thing as partial CA.* ---------- Forwarded message --------- From: Peter Hobbs <[log in to unmask]> Date: Sun, 1 May 2022 at 22:26 Subject: May 2022 CA Scoopit newsletter To: Amir Kassam <[log in to unmask]> Dear Amir: Here is our May 2022 Conservation Agriculture Scoopit Research Update.

The paper describes the many hurdles and drudgery women face farming their land with out-migration of male members of the household. For example, fewer rights over land make it more difficult for women to access subsidies, finance, or mechanization. The paper describes 3 ways that sustainable mechanization can empower women and respond to their predicament. The paper also provides a catalogue that highlights the potential for smallholder farmers, including women, to earn an income via mechanization hire service. The information for each machine or equipment is also included in this paper. The target audience includes extensionists, gender experts, agricultural engineers, government officials, donors, micro-finance institutions, and implementing partners. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015916/2022/05/01/empowering-women-farmers-a-mechanization-catalogue-for-practitioners> <https://www.scoop.it/share/post/twitter/4132015916?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132015916?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132015916?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132015916> Improved soil structural stability under no-tillage is related to increased soil carbon in rice paddies: Evidence from literature review and field experiment. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014932/2022/05/01/improved-soil-structural-stability-under-no-tillage-is-related-to-increased-soil-carbon-in-rice-paddies-evidence-from-literature-review-and-field-experiment> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S2352186421008130> - Today, 5:04 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014932/2022/05/01/improved-soil-structural-stability-under-no-tillage-is-related-to-increased-soil-carbon-in-rice-paddies-evidence-from-literature-review-and-field-experiment> Qi, J.Y., Han, S.W., Lin, B.J., Xiao, X.P., Jensen, J.L., Munkholm, L.J. & Zhang, H.L. 2022.

Four tillage practices: no-tillage, rotary tillage and moldboard plow tillage with rice straw retention (NTS, RTS and CTS respectively), and moldboard plow tillage with rice straw removal (CT). Additionally, the meta-analysis showed that no-tillage increased the macroaggregate content, WSA and MWD. They conclude that In rice paddies, the increased macroaggregate content may contribute to increasing SOC, which improves soil structural stability (SSS) under no-tillage. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014932/2022/05/01/improved-soil-structural-stability-under-no-tillage-is-related-to-increased-soil-carbon-in-rice-paddies-evidence-from-literature-review-and-field-experiment> <https://www.scoop.it/share/post/twitter/4132014932?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132014932?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132014932?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132014932> Scaling up conservation agriculture: An exploration of challenges and opportunities through a stakeholder engagement process. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017218/2022/05/01/scaling-up-conservation-agriculture-an-exploration-of-challenges-and-opportunities-through-a-stakeholder-engagement-process> From doi.org <https://doi.org/10.1002/jeq2.20317> - Today, 4:46 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017218/2022/05/01/scaling-up-conservation-agriculture-an-exploration-of-challenges-and-opportunities-through-a-stakeholder-engagement-process> Reimer, A., Doll, J.E., Boring, T.J. & Zimnicki, T. 2022.

The information is based on participatory discussions with farmers in Michigan. They looked at policy, economic and structural barriers that inhibit adoption of conservation systems. The results were complex with barriers and opportunities, including markets, social networks, human capital, and conservation programs. Making it more difficult are many community constraints, market access and availability problems, climatic and environmental changes, and policies (governmental and corporate) that cross-pressure farmers when it comes to making conservation decisions. Better understanding these constraints will help with the adoption of CA. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017218/2022/05/01/scaling-up-conservation-agriculture-an-exploration-of-challenges-and-opportunities-through-a-stakeholder-engagement-process> <https://www.scoop.it/share/post/twitter/4132017218?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017218?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017218?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017218> Chapter 9 - Microbial impact on climate-smart agricultural practices <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017191/2022/05/01/chapter-9-microbial-impact-on-climate-smart-agricultural-practices> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/B9780323905718000092> - Today, 4:23 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017191/2022/05/01/chapter-9-microbial-impact-on-climate-smart-agricultural-practices> Ajala, O.A., Ajibade, F.O., Oluwadipe, O.R., Nwogwu, N.A., Adelodun, B., Guadie, A., Ajibade, T.F., Lasisi, K.H. & Adewumi, J.R. 2022.

Wheat yield and biomass, and several soil properties were measured (pH, soil nutrients, soil organic matter potentially mineralizable nitrogen, total microbial activity and heavy metals) throughout the 10-year study. Wheat yield was better under organic compared to mineral fertilizer. The application of organic amendments under MT resulted in a promising management agro-ecosystem compared to the mineral fertilized because crop nutrients came from organic wastes, no herbicides were applied while the yields were higher. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014830/2022/05/01/organic-amendment-vs-mineral-fertilization-under-minimum-tillage-changes-in-soil-nutrients-soil-organic-matter-biological-properties-and-yield-after-10-years> <https://www.scoop.it/share/post/twitter/4132014830?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132014830?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132014830?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132014830> Herbicide in Weed Management of Wheat (Triticum aestivum L.) and Rainy Season Rice (Oryza sativa L.) under Conservation Agricultural System <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015766/2022/05/01/herbicide-in-weed-management-of-wheat-triticum-aestivum-l-and-rainy-season-rice-oryza-sativa-l-under-conservation-agricultural-system> From www.mdpi.com <https://www.mdpi.com/2073-4395/11/9/1704> - Today, 3:27 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015766/2022/05/01/herbicide-in-weed-management-of-wheat-triticum-aestivum-l-and-rainy-season-rice-oryza-sativa-l-under-conservation-agricultural-system> Zahan, T., Hossain, M.F., Chowdhury, A.K., Ali, M.O., Ali, M.A., Dessoky, E.S., Hassan, M.M., Maitra, S. & Hossain, A. 2021.

This study looked at a CA based rice (direct seeded)-wheat-mungbean cropping pattern over two years of study. The goals were to study the types and distribution of weeds in non-puddled rice and following strip-tilled wheat fields, and to find the most economic way to manage the weeds in both crops. The latter goal included using herbicides. The most most effective treatments involved two herbicides with one applied pre- and one post emergent in wheat and two other herbicides in direct seeded rice also applied pre- and post-emergent. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015766/2022/05/01/herbicide-in-weed-management-of-wheat-triticum-aestivum-l-and-rainy-season-rice-oryza-sativa-l-under-conservation-agricultural-system> <https://www.scoop.it/share/post/twitter/4132015766?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132015766?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132015766?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132015766> Mobilizing Greater Crop and Land Potentials with Conservation Agriculture <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017046/2022/05/01/mobilizing-greater-crop-and-land-potentials-with-conservation-agriculture> Today, 2:56 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017046/2022/05/01/mobilizing-greater-crop-and-land-potentials-with-conservation-agriculture> Kassam, A., Gottlieb, B., Friedrich, T., Gonzalez, E., Trivino, P.

It describes the role of CA in accomplishing this goal. They explain that CA can raise productivity, reduce inputs, regenerate degraded land, reduce erosion, and improve the flow of ecosystem services and so contribute to several SDGs. It highlights that CA is spreading globally at an annual rate of about 10 mHa per year. In 2015-16 it was estimated to cover 180 Mha with 48% in the Global South. It further discusses what is needed for CA to contribute to SDGs to contribute to lasting quality of human life and nature. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017046/2022/05/01/mobilizing-greater-crop-and-land-potentials-with-conservation-agriculture> <https://www.scoop.it/share/post/twitter/4132017046?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017046?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017046?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017046> Evaluation of different infiltration models under long term conservation agricultural practices <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017006/2022/05/01/evaluation-of-different-infiltration-models-under-long-term-conservation-agricultural-practices> Today, 2:33 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017006/2022/05/01/evaluation-of-different-infiltration-models-under-long-term-conservation-agricultural-practices> Ghosh, T., Maity, P.P., Das, T.K., Krishnan, P., Bhatia, A., Roy, M. & Sharma, D.K. 2020.

Treatments included a check (CT), Permanent narrow beds (PNB) and wide beds (PBB) with and without residue (+R) and NT. The initial and cumulative infiltration rates were highest in the PBB+R treatment and lowest in CT. Bed planting with residue was better than BP without residue that was better than NT without residue. After checking the model performance, it was found that simple empirical Kostiakov (1932) infiltration model represented the infiltration rate and time relationship in a better way and characterized the best fit with the experimentally observed field infiltration data. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017006/2022/05/01/evaluation-of-different-infiltration-models-under-long-term-conservation-agricultural-practices> <https://www.scoop.it/share/post/twitter/4132017006?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017006?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017006?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017006> Conservation agriculture practice influences soil organic carbon pools in intensive rice-based systems of the Eastern Indo-Gangetic Plain <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017249/2022/05/01/conservation-agriculture-practice-influences-soil-organic-carbon-pools-in-intensive-rice-based-systems-of-the-eastern-indo-gangetic-plain> From doi.org <https://doi.org/10.1111/sum.12798> - Today, 5:12 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017249/2022/05/01/conservation-agriculture-practice-influences-soil-organic-carbon-pools-in-intensive-rice-based-systems-of-the-eastern-indo-gangetic-plain> Islam, M.A., Bell, R.W., Johansen, C., Jahiruddin, M., Haque, M.E. & Vance, W. 2022.

CT had higher CO2 emission compared with strip planting or bed planting as did high residue return. In the legume-dominated rotation, neither practice sequestered SOC. They conclude that strip planting with high levels of crop residue return can be an effective and quick strategy in either slowing the loss of SOC or improving C sequestration. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017249/2022/05/01/conservation-agriculture-practice-influences-soil-organic-carbon-pools-in-intensive-rice-based-systems-of-the-eastern-indo-gangetic-plain> <https://www.scoop.it/share/post/twitter/4132017249?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017249?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017249?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017249> Rates, factors, and tolerances of water erosion in the Cerrado biome (Brazil): A meta-analysis of runoff plot data <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014912/2022/05/01/rates-factors-and-tolerances-of-water-erosion-in-the-cerrado-biome-brazil-a-meta-analysis-of-runoff-plot-data> From doi.org <https://doi.org/10.1002/esp.5273> - Today, 4:53 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014912/2022/05/01/rates-factors-and-tolerances-of-water-erosion-in-the-cerrado-biome-brazil-a-meta-analysis-of-runoff-plot-data> Fonseca, M.R.S., Uagoda, R. & Chaves, H.M.L. 2022.

The objective of the present research was to compile, systematize, and statistically analyze the existing erosion plot data in the Brazilian Cerrado, correlating the observed results with different environmental and management factors, and with the corresponding soil loss tolerances. The research results provide useful elements for the development of sound conservation policies in the Cerrado and in other similar savannas of the world. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014912/2022/05/01/rates-factors-and-tolerances-of-water-erosion-in-the-cerrado-biome-brazil-a-meta-analysis-of-runoff-plot-data> <https://www.scoop.it/share/post/twitter/4132014912?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132014912?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132014912?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132014912> Transition to conservation agriculture: how tillage intensity and covering affect soil physical parameters <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015849/2022/05/01/transition-to-conservation-agriculture-how-tillage-intensity-and-covering-affect-soil-physical-parameters> From soil.copernicus.org <https://soil.copernicus.org/articles/8/213/2022/> - Today, 4:31 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015849/2022/05/01/transition-to-conservation-agriculture-how-tillage-intensity-and-covering-affect-soil-physical-parameters> Sartori, F., Piccoli, I., Polese, R. & Berti, A. 2022.

Bulk density (BD), penetration resistance (PR), soil hydraulic saturated conductivity, and sorptivity were used to evaluate soil quality obtained by combining three tillage intensities (conventional tillage – CT; minimum tillage – MT; no tillage – NT) with three winter soil coverings (bare soil – BS; tillage radish cover crop – TR; winter wheat cover crop – WW). Reduced tillage coupled with WW improved soil physical properties even below the tilled layer, as evidenced by root-growth-limiting condition reductions. They conclude that, despite the increase in BD and PR due to reduced tillage, the strategy improved soil functioning and particularly soil hydraulic conductivity. In the short term, the WW cover crop moderately increased physical soil parameters, whereas TR had negligible effects. This study demonstrates that, to quantify CA, several soil physical parameters should be monitored. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132015849/2022/05/01/transition-to-conservation-agriculture-how-tillage-intensity-and-covering-affect-soil-physical-parameters> <https://www.scoop.it/share/post/twitter/4132015849?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132015849?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132015849?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132015849> Changes in soil physicochemical properties and bacterial communities at different soil depths after long-term straw mulching under a no-till system <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017172/2022/05/01/changes-in-soil-physicochemical-properties-and-bacterial-communities-at-different-soil-depths-after-long-term-straw-mulching-under-a-no-till-system> From soil.copernicus.org <https://soil.copernicus.org/articles/7/595/2021/> - Today, 4:10 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017172/2022/05/01/changes-in-soil-physicochemical-properties-and-bacterial-communities-at-different-soil-depths-after-long-term-straw-mulching-under-a-no-till-system> Zhou, Z., Li, Z., Chen, K., Zeng, X., Yu, H., Guo, S., Shangguan, Y., Chen, Q., Fan, H., Tu, S., He, M. & Qin, Y. 2021.

Straw was removed (CK) or mulched (SM) in this 12-year study. Organic carbon, nutrients, and bacterial abundance were reduced by depth, but pH increased. SM significantly increased total N, inorganic N, available P, available potassium, and soil water content at 0-5 cm, total organic C content at 0-10 cm, and dissolved organic C and N contents at 0-20 cm compared to CK. The study also reports data on the effect of SM vs CK on various bacterial groups. Overall, they conclude that the SM treatment is highly recommended under a no-till system because of its benefits to soil fertility and bacterial abundance. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017172/2022/05/01/changes-in-soil-physicochemical-properties-and-bacterial-communities-at-different-soil-depths-after-long-term-straw-mulching-under-a-no-till-system> <https://www.scoop.it/share/post/twitter/4132017172?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017172?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017172?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017172> Adoption of agricultural technology in the developing world: A meta-analysis of the empirical literature <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014815/2022/05/01/adoption-of-agricultural-technology-in-the-developing-world-a-meta-analysis-of-the-empirical-literature> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0305750X2100214X> - Today, 3:36 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014815/2022/05/01/adoption-of-agricultural-technology-in-the-developing-world-a-meta-analysis-of-the-empirical-literature> Ruzzante, S.

The contend that adoption of many seemingly beneficial technologies remain low. This study looks at various reasons that explain adoption from 367 regression models from published literature. They find that farmer education, household size, land size, access to credit, land tenure, access to extension services, and organization membership positively correlate with the adoption of many agricultural technologies. Improved varieties and chemical inputs are adopted more readily on larger farms, which casts doubt on the scale-neutrality of these technologies. Credit can positively influence adoption, but researchers should measure whether farmers are credit constrained, rather than simply whether or not they have access to credit. They conclude that efforts to promote agricultural technologies in the developing world must be adapted to suit local agricultural and cultural contexts. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132014815/2022/05/01/adoption-of-agricultural-technology-in-the-developing-world-a-meta-analysis-of-the-empirical-literature> <https://www.scoop.it/share/post/twitter/4132014815?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132014815?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132014815?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132014815> Chapter 2 - Conservation agricultural practices under organic farming <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017082/2022/05/01/chapter-2-conservation-agricultural-practices-under-organic-farming> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/B9780128223581000146> - Today, 3:12 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017082/2022/05/01/chapter-2-conservation-agricultural-practices-under-organic-farming> Mandal, A., Dhaliwal, S.S., Mani, P.K. & Toor, A.S. 2021.

Advantages include less erosion and degradation due to improved soil structure, increase in soil carbon stock, diversity of macro- and micro-organisms, and reduction in nutrient loss through run-off and leaching. But since CA and OF have contrasting strategies there are difficulties that need to be overcome. These include weed control, soil compaction, slow mineralization rate, restricted choice of crops, unavailable equipment, low incentives and funding, and links to organic markets. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017082/2022/05/01/chapter-2-conservation-agricultural-practices-under-organic-farming> <https://www.scoop.it/share/post/twitter/4132017082?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017082?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017082?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017082> Review of and recommendations for Custom Hiring Centers for mechanization in Nepal and the Asian region <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017014/2022/05/01/review-of-and-recommendations-for-custom-hiring-centers-for-mechanization-in-nepal-and-the-asian-region> From www.fao.org <https://www.fao.org/documents/card/en/c/cb7964en/> - Today, 2:42 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017014/2022/05/01/review-of-and-recommendations-for-custom-hiring-centers-for-mechanization-in-nepal-and-the-asian-region> Justice, S. 2021.

The paper reports that there has been minimal reliable reporting or evidence on the success of their efforts. Yet, there is very good reason to believe that with refined backstopping and informed selection, CHCs can be successfully used to provide mechanization access for underserved geographical areas and their communities. The paper ends with recommendations, observations and considerations for policy and agricultural development professionals and the existing CHC's management committees (MCs) around establishing and/or the improving CHCs and their management. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4132017014/2022/05/01/review-of-and-recommendations-for-custom-hiring-centers-for-mechanization-in-nepal-and-the-asian-region> <https://www.scoop.it/share/post/twitter/4132017014?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4132017014?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4132017014?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4132017014> <https://drive.google.com/u/0/settings/storage?hl=en&utm_medium=web&utm_source=gmail&utm_campaign=storage_meter&utm_content=storage_normal> <https://www.google.com/intl/en/policies/terms/> <https://www.google.com/intl/en/policies/privacy/> <https://www.google.com/gmail/about/policy/> ######################################################################## To unsubscribe from the CA-Cop-L list, click the following link: &*TICKET_URL(CA-Cop-L,SIGNOFF);
