This study explores how domestic entrepreneurs have been benefiting from the growing global demand for sustainable agribusiness by establishing themselves in the agricultural bio-inputs sector. Aiming to explore how developing countries can build agro-industrial capabilities that go beyond farming, a case study was conducted in Argentina giving the country’s large domestic market for agricultural inputs. The assessment was based on official data and a survey conducted with a sample of 14 Argentinean companies. Results revealed a growing number of domestic companies in the bio-inputs market, which accounted for 74% of the total number of companies by 2022. Contextual aspects that favored domestic players include private investments by local entrepreneurs, the use of locally available technologies, support from public innovation centers and assertive market strategies. Principal component analysis revealed different business models, which include companies focusing on the development of new products, companies with professional industrial plants for large-scale production and companies with a strong marketing component reaching out to farmers. The global growth of sustainable bio-based agricultural production offers areas of opportunities for domestic investments in cleaner agro-industrial sectors that go beyond the primary production of commodities and can build industrial capabilities in developing countries.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"2 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136023056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Needs Analysis and Payback Models for Tractor Design Based on Field Data from Farmers in Sudan","authors":"Hamza Ahmed, Erika E. Miller","doi":"10.3390/world4040044","DOIUrl":"https://doi.org/10.3390/world4040044","url":null,"abstract":"The adoption of agricultural machinery in countries with a developing economy can have a significant impact on improving well-being and pro-poor growth. However, this requires farmers to buy into mechanized farming, which is more likely to happen if the machinery meets their needs. The objective of this paper is to identify deciding factors for traditional farmers to adopt machinery and identify design requirements. Payback models were developed based on these design requirements, willingness to pay, and expected returns. Thirty-six farmers in Sudan were interviewed throughout 2019–2021. Six of these farmers were provided tractors during 2020 and 2021. Differences in net-profits between the 30 control and 6 treatment farms during the mechanized farming seasons were used in the models for expected profits. There were no significant differences in tractor design preferences between the treatment and control groups. Two cost models were estimated using a 95% confidence interval: entire Δ profit (entire additional profit from mechanized farming above nonmechanized) and percentage of total profit (percentage of total net-profits willing to spend). For the average farm size in this study (44.39 acres) and a market available tractor that satisfied all farmer needs, payback was 3.92 years [2.34, 8.54] and 4.57 years [3.39, 6.38] for the models, respectively.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"49 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136263278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the 1970s, it became conventional wisdom that “the population explosion” constituted a threat to humanity and to sound social, economic and ecological development. This conviction was clearly demonstrated at UN conferences on the environment (1972) and population (1974). It was also confirmed in the important UN report Our Common Future, presented by the Brundtland Commission in 1987. Since the 1990s, international interest in population issues has decreased dramatically and has even become a taboo in certain academic and political discourses. This paper will try to analyze some of the reasons for these changes in attitudes and will present proposals on how to push the population issue back on to the international agenda.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135266481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Later papers, using reportedly improved econometric models and data, largely reversed these early findings by estimating that natural resources improve economic performance. However, this changing coefficient on natural resource dependence over time may not only be a function of model or data quality. Masked by this evolution in the economics literature is the possibility that the fundamental relationship between natural resources and economic performance has changed over the past several decades. This paper sheds a new perspective on the substantial resource curse literature by repeatedly estimating a single econometric model on data that evolve over time. The coefficient on natural resource dependence is estimated to steadily increases with the passage of time from a value that is negative and significant (for 1970, the basis for much of the early literature) to a positive and significant value a few decades later. Whatever natural resource estimated initially with data from 1970 seems to have evolved into a resource blessing over time.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"33 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135413394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anoa are categorized as vulnerable to extinction on the IUCN red list. There are two species of Anoa, namely Lowland Anoa (Bubalus depressicornis) and Mountain Anoa (Bubalus quarlesi). In this study, a comparison of potential habitat models for Anoa species was conducted using Machine Learning algorithms with the Maximum Entropy (MaxEnt) and Random Forest (RF) methods. This modeling uses eight environmental variables. Where based on the results of Bubalus quarlesi potential habitat modeling, the RF 75:25 model is the best algorithm with the highest variable contribution, namely humidity of 82.444% and a potential area of 5% of Sulawesi Island, with an Area Under Curve (AUC) of 0.987. Meanwhile, the best Bubalus depressicornis habitat potential model is the RF 70:30 algorithm, with the highest variable contribution, namely population of 88.891% and potential area of 36% of Sulawesi Island, with AUC 0.967. This indicates that Anoa extinction is very sensitive to the presence of humidity and human population levels.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135696440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Effects of Restoration and Conservation of Riparian Vegetation on Sediment Retention in the Catchment Area of Corumbá IV Hydroelectric Power Plant, Brazil","authors":"Natália Pezzi Fachinelli, Amaro Olímpio Pereira","doi":"10.3390/world4040040","DOIUrl":"https://doi.org/10.3390/world4040040","url":null,"abstract":"Vegetation cover and land use are important factors related to the capacity of ecosystems to provide soil loss regulation and sediment retention services, which are highly relevant for sediment management in watersheds draining into reservoirs with multiple water uses. One way to ensure the protection and recovery of vegetation by landowners in Brazil is the implementation of the federal Native Vegetation Protection Law (NVPL), which designates environmentally sensitive areas as Areas of Permanent Preservation (APPs), aiming to conserve water resources and prevent soil erosion. The benefits of riparian vegetation in the catchment of Corumbá IV Hydroelectric Power Plant (HPP), located in the Brazilian Cerrado, were analyzed considering landscape reconfigurations from a baseline condition (year 2011) in order to account for the recovery of riparian vegetation by the agricultural sector, as foreseen in the NVPL. The Sediment Delivery Ratio (SDR) model from the InVEST (Integrated Valuation of Environmental Services and Tradeoffs) package was used to map and quantify variations in sediment export and sediment retention throughout the catchment. The reduction in annual sediment export in the drainage basin of the Corumbá IV reservoir reached −27% in the scenario where the total deficit of riparian APPs occupied by pasture or agriculture in the baseline map (41.000 ha) are recovered. While 14% of riparian APP are occupied by crops versus 86% occupied by pasture in the drainage basin of the Corumbá IV HPP, the recovery of riparian zones occupied by agricultural activities resulted in the greatest benefits in sediment retention for the reservoir. The methodology employed in this study can support the prioritization of sectoral efforts for the restoration and conservation of native vegetation, considering the highest returns in benefits perceived by water users affected by sediment input in reservoirs. The study’s results reinforce the importance of conserving vegetation in riparian areas and their surroundings for sediment retention, highlighting the role of these areas as assets in providing water-related ecosystem services. For future developments, it is suggested to assess the interconnections among the energy, water, and food sectors to better understand the barriers and challenges to the maintenance and improvement of water-related ecosystem services in the catchment area of Corumbá IV HPP.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134886808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By setting as a functional unit the production of 10 kg of greenhouse tomato, the study investigates the social dynamics and challenges faced by migrant workers within the industry. The research sheds light on the negative aspects of intensive greenhouse farming for migrants, i.e., labor conditions, health and safety risks, social inequality, and exploitation of migrant labor. Utilizing document analysis, this study contributes to the field of S-LCA by providing a nuanced understanding of the social dimensions surrounding tomato production and migrant workers’ experiences. It emphasizes the need for sustainable practices, improved labor conditions, and ethical considerations to ensure a socially responsible tomato farming industry. The findings have implications for policymakers, industry stakeholders, and consumers, providing insights for informed decision-making and the promotion of socially sustainable agricultural practices that prioritize the well-being and rights of migrant workers in the context of intensive greenhouse farming in Almeria.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136236418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demographic dividend is mainly the result of fertility decline (lower number of births, lower population growth) which translates into a population age structure with a larger work force (age 15–64) and a smaller proportion of children (age 0–14), together with initially few elderly persons (age 65+). In turn, this favors economic growth, but it also has many consequences for households and for state budgets, as well as long-term consequences for population size and the environment. The first part of this paper shows the small correlations at the national macro-economic level between dependency ratios and economic growth. The second part shows the strong correlations at the household level between levels of fertility, child mortality and modern education. The third part discusses the many other correlates of the demographic dividend. The often-cited and controversial focus of the demographic dividend on economic growth hides many other positive effects of fertility control on households, on state budgets, and, in the long-run, on societies and the environment.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"37 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136374465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental science mandates that continued growth of the human enterprise on a finite planet is unsustainable and already in overshoot. Indeed, 3 billion is an evidence-based target number, for our species in competition with all non-human life-forms. We must achieve zero population growth and, ultimately, a massive decrease. Commonly, even among environmentalists who are not “population-deniers”, human numbers are seen as a given, to be adapted to rather than influenced or managed. Yet, just and appropriate interventions exist. The fundamental requirement is the empowerment of women, removing the barriers in many settings to their education (including environmental education, and the reproductive ethics of smaller families) and to realistic, voluntary access to contraception. Wherever “reproductive health” includes access to rights-based family planning, this not only promotes the health of the planet but also women’s health through, inter alia, their choice to have fewer and better-spaced children. This is ethical, pragmatic, and cost-effective—a prime example of preventive medicine. Politicians (mostly men) everywhere must embrace this long-term thinking and significantly increase the currently inadequate funding of contraceptive care. Herein is another Scientists’ Warning: there is just one planet for all life.","PeriodicalId":23705,"journal":{"name":"WORLD","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135937864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
