9pgs, Soil loss due to crop harvest contributes to land degradation, and knowledge of this challenge can guide the choice of crops for sustainable agriculture. Nigeria is the largest producer of cassava (Manihot esculenta Crantz) and the third largest producer of peanut (Arachis hypogaea Linn) in the world. Due to limited information on soil loss during peanut and cassava harvests worldwide, and cost of nutrient loss, a two-year field experiment was conducted to compare soil loss due to harvesting of peanut and cassava and to estimate cost of nutrient loss due to crop harvest under traditional agriculture. Peanut pod yields of 2.39 and 2.08 t ha–1harvest–1 removed 0.62 and 0.58 t ha–1 harvest–1 during peanut harvest, respectively, for years 1 and 2. Similarly, cassava yields of 22.71 and 21.40 t ha–1 harvest–1 removed 1.11 and 0.91 t ha–1harvest–1 during cassava harvest, respectively, for years 1 and 2. Crop yields strongly correlated with soil loss due to peanut harvest (R2= 0.36; p < 0.001) and soil loss due to cassava harvest (R2 = 0.23; p < 0.01). Significantly higher soil loss due to cassava harvest compared to peanut harvest can be ascribed to higher cassava yield. Also, soil nutrient loss due to crop harvest was significantly (p < 0.001) higher for cassava compared with peanut by 27.6% phosphorus (P) and 73.7% potassium (K) for the first year and 39.2% P and 79.1% K for the second year. Fertilizer equivalent cost of P and K losses due to cassava harvest for the two years was higher than that of peanut by US$29 ha–1. The study indicated that the intensity of nutrient loss by harvesting is largely dependent on the crop type, and harvesting of cassava can deplete soil nutrients faster than that of peanut under traditional agriculture. Sequential planting of cassava (deep rooted crop) followed by peanut (shallow rooted crop) as a crop rotation management practice is recommended to mitigate soil loss due to continuous harvesting of cassava, and harvesting with thorough shaking technique is also suggested to reduce nutrient loss potential of crop harvesting.
22pgs, We introduce the “coordination frontier” (CF), a simple practical tool to assess the likelihood of success of voluntary coordination in situations where, ex ante, the collective action solution provides an appealing alternative (e.g., for pest and disease control). We demonstrate the value of information conveyed by the CF, explain how to construct the CF from experimental data, and show how to apply the CF in practice. We illustrate the concept with an application to data from a framed field economic experiment, which was designed to elicit the preferences of Florida's citrus growers regarding their willingness to coordinate actions to combat citrus greening disease. This is a highly relevant case study not only because of the significant impact caused by citrus greening on Florida's citrus industry but also because a voluntary area-wide pest management program to control it had been established in 2010 and eventually failed; a similar program is now in place in California, where the disease spread is at an earlier stage. Had the CF been available in Florida, estimates of the (aggregate) chances of successful coordination could have been shared with growers to update their beliefs regarding the chances of successful coordination to help reduce strategic uncertainty. Policymakers in California could use the CF in such way and devise ways to encourage participation to increase the chances of reaching a desired coordination threshold.
9 pages, Humans have improved plants for their utility through selective self-pollination, crossing, and progeny selection for >10,000 years, largely based on physical characteristics. Less than 200 years ago, the genetic basis of heritability in selection was revealed, enabling breeders to accelerate genetic gain. Breakthroughs in genomics and molecular markers for the past century have enabled breeders to locate and select genomic regions affecting desirable traits, improving breeding precision. Transgenesis has enabled crop insertion of desirable exogenous genes, enabling de novo functionality. These technologies, along with agronomic practices, have generated more than sixfold yield improvements in crops such as corn in the past century. Gene editing, with its unique ability to precisely edit, change expression, and move genes within a crop's genome, has the potential to be the next breakthrough technology. For this to come to fruition, it is critical to take a holistic view considering perspectives of scientists, farmers, regulators, and consumers.

e-ISSN: 2455-6270; p-ISSN: 2455-7455, In India even today more than half of the population is involved with agriculture thus making it the primary and important activity. Since most of the Indian population still lives in rural regions, so for this reason agriculture and related activities constitute the major source of revenue. Nonetheless, irrespective of the government's numerous efforts, there is still a huge disparity between a farmer's actual investment and the return on investment. As a result, the purpose of this research is to investigate the numerous factors
which impact farmers' attitudes about agricultural produce marketing. The study revealed that the majority of farmers belonging to the study region are low-income subsistence farmers who are more susceptible to agricultural hazards. Substantial farmers have better access to financing, but they do not contact financial institutions because of their large precautionary reserves.
11 pages., Declining crop productivity is a great challenge facing smallholder farmers in Tanzania. Agro-ecological practices can improve crop productivity in a sustainable way and produce healthy food among smallholder farmers. Initiation of “Farmer-Led Research of Agro-Ecological Practices” (FLRAG) may enhance farmers’ capacities for innovation and co-develop suitable agro-ecological practices. This study aimed at identifying factors influencing smallholder farmers to participate in FLRAG. A cross-sectional survey was used to collect qualitative and quantitative data from 90 smallholder farmers in Mvomero, Bagamoyo and Masasi districts in Tanzania. Data were also collected from key informants who were extension officers. The study identified that experience in farming, easiness in accessing agro-ecological inputs, interest in doing experiments and farm size ownership are the factors that substantially influence smallholder farmers to participate in FLRAG. Therefore, researchers are advised to select participants of FLRAG by considering the mentioned factors. Furthermore, farmers selected to participate in FLRAG are advised to the use of ugunduzi app” that was developed purposefully to enhance agro-ecological research in order to test and understand its potential on smoothing agro-ecological research activities.
16 pages, The U.S. Midwest is a major producer of grain, meat, dairy, eggs, and other major agricultural commodities. It has also been increasingly impacted by climate change-related extreme weather over the last decade as droughts, extreme rains, floods, and, most recently, a severe derecho have damaged crops, livestock, and livelihoods. Climate and agricultural scientists and other stakeholders are concerned that without major shifts away from degrading practices toward regenerative systems, long-term sustainability will be compromised. We used cumulative logistic regression to analyze data from a 2020 survey of 1,059 Iowa farmers to examine (1) how farmers are adapting to increasingly variable and extreme weather-related to climate change and (2) whether selected factors were associated with different kinds of adaptive (e.g., increased use of cover crops) or potentially maladaptive (e.g., increased use of pesticides) actions. Our results found that many farmers have been taking adaptive and maladaptive actions. Stewardship ethics, attitudes toward adaptive action, and integration in conservation-related networks were consistent, positive predictors of increases in adaptive practices. On the other hand, faith in crop insurance as a coping strategy, farm scale, and other factors were associated with some maladaptive actions, with several positive predictors of adaptation also being positive predictors of maladaptation, use of pesticides and drainage in particular. This research contributes to the growing literature on climate risk management and adaptation in agricultural landscapes by providing empirical evidence of the factors related to farmers' adaptive and maladaptive actions.
12 pages, To date, there has been an increase in genome modification biotechnologies that improve production and food security but the process has not been accompanied by the delivery of information about them intended for citizens. This is essential considering that to achieve better health, food security and sustainability these biotechnologies need to be incorporated into production systems. This study aimed to explore perceptions and attitudes of Chilean citizens towards the use of genome modifications with an emphasis on transgenes and genome editing (CRISPR). An electronic questionnaire was applied, and afterwards the results were analysed through descriptive statistics, GLM, Spearman’s correlation and Wilcoxon Signed Rank test. A total of 702 questionnaires were analysed. High awareness of concepts such as transgenic and cloning was reported with CRISPR being the least known term. Most respondents perceived negative effects on health regarding the consumption of genetically modified products, with women having a significantly more negative attitude. Still, a high willingness to use CRISPR for improving animal and human health was reported. When comparing vegetable and animal products that underwent CRISPR or transgenes, the willingness to consume these products was higher for vegetables. The results show that changes in perception can be achieved after providing the definition of CRISPR and transgenic, therefore, consumer education seems to be essential. Science communication focused on making information about genome modification biotechnologies available to citizens could promote more positive attitudes and perceptions and facilitate their future implementation in the country.
16 pages, via Online Journal, Crop genetic resources constitute a ‘new’ global commons, characterized by multiple layers of activities of farmers, genebanks, public and private research and development organizations, and regulatory agencies operating from local to global levels. This paper presents sui generis biocultural community protocols that were developed by four communities in Benin and Madagascar to improve their ability to contribute to, and benefit from, the crop commons. The communities were motivated in part by the fact that their national governments’ had recently ratified the Plant Treaty and the Nagoya Protocol, which make commitments to promoting the rights of indigenous peoples, local communities and farmers, without being prescriptive as to how Contracting Parties should implement those commitments. The communities identified the protocols as useful means to advance their interests and/or rights under both the Plant Treaty and the Nagoya Protocol to be recognized as managers of local socio-ecological systems, to access genetic resources from outside the communities, and to control others’ access to resources managed by the community.
