To discover new bisamide compounds with insecticidal and fungicidal activities, 19 novel cyproflanilide derivatives containing 1,2,4-oxadiazole group were designed and synthesized according to the principle of biologically active factor splicing. Preliminary biological assay data indicated that the majority of target compounds demonstrated significant insecticidal activity against Lepidopteran pests. Meanwhile, compounds 5p and 5q showed 97.22 and 100% lethality against Tetranychus cinnabarinus at 400 mg L-1, which were better than cyproflanilide (41.11% at 400 mg L-1). In addition, it is exciting that we have achieved our initial goals as some of the target compounds exhibited both insecticidal and fungicidal activities. For instance, compounds 5b and 5c showed 59.26 and 74.07% fungicidal activities against Cucumber downy mildew at 400 mg L-1, as well as 100% insecticidal activity against Plutella xylostella and armyworm at 100 mg L-1. Compound 5h showed 100% insecticidal activity against armyworm at 10 mg L-1, and also displayed 66.67% fungicidal activity against Cucumber downy mildew at 400 mg L-1. The inhibition rate of compounds 5l and 5s against Cucumber downy mildew reached 88.89 and 96.30% at 400 mg L-1. This work showed the effectively fungicidal application of 1,2,4-oxadiazole group in bisamide compounds and provides insights for optimal structural design. 1 1,2,4oxadiazole 124oxadiazole oxadiazole 1,2,4 2 4 splicing pests Meanwhile p q 9722 97 22 97.2 40 L1, L1 L 1, L-1 41.11% 4111 41 11 (41.11 L1. .

RESUMO A aplicação de esgoto sanitário utilizando o gotejamento subsuperficial contribui para mitigar os problemas atuais de disponibilidade de água e produção de alimento. Objetivou-se avaliar o feijão-caupi recebendo esgoto sanitário por gotejadores operando com diferentes vazões e profundidades. Os gotejadores operaram com as vazões de 1,6 e 3,8 L h-1 e foram instalados nas profundidades de 0, 5, 10, 15, 20, 25 e 30 cm. O feijão-caupi foi cultivado em vasos de 65 L preenchidos com solo argiloso em casa de vegetação. Utilizou-se esgoto sanitário sintético e a quantidade aplicada nos vasos foi baseada no elemento limitante, que no caso foi o nitrogênio, para o cultivo do feijão-caupi. O manejo da irrigação foi realizado com sondas de TDR. Avaliou-se a germinação e as respostas fisiológicas e morfologia das raízes do feijão-caupi. A ascensão capilar, quando a água foi aplicada em profundidade, não foi suficiente para umedecer de maneira uniforme a superfície do solo. As variáveis de germinação apresentaram um decréscimo em função do aumento das profundidades de instalação dos gotejadores. A distribuição da água com o aumento da profundidade dos emissores foi responsável pelos prejuízos nas respostas fisiológicas e morfológicas das raízes feijão-caupi. As vazões dos gotejadores não afetaram a germinação do feijão-caupi. Utilizar o sistema de irrigação por gotejamento subsuperficial não foi apropriado para o feijão-caupi nas condições deste estudo. alimento Objetivouse Objetivou se feijãocaupi feijão caupi 16 1 6 1, 38 3 8 3, h1 h h- 0 5 10 15 20 2 cm vegetação Utilizouse Utilizou limitante nitrogênio feijãocaupi. caupi.

ABSTRACT The application of sanitary sewage using subsurface drip irrigation contributes to mitigating the current problems of water availability and food production. The aim in this study was to evaluate cowpea receiving sanitary sewage through drippers operating at different flow rates and depths. The drippers operated at flow rates of 1.6 and 3.8 L h-1 and were installed at depths of 0, 5, 10, 15, 20, 25, and 30 cm. Cowpea was grown in 65 L pots filled with sandy clay soil in a greenhouse. Synthetic sanitary sewage was used and the amount applied to the pots was based on the limiting element, which in this case was nitrogen, for growing cowpea. Irrigation was managed using TDR probes. Germination and the physiological responses and morphology of cowpea roots were assessed. Capillary rise, when water was applied in subsurface, was not sufficient to evenly moisten the soil surface. The germination variables decreased as a result of the increase in drip installation depths. The distribution of water as the depth of the emitters increased was responsible for the damage to the physiological and morphological responses of cowpea roots. The flow rates of the drippers did not affect the germination of cowpea. Using the subsurface drip irrigation system was not appropriate for growing cowpea under the conditions of this study. production 16 1 6 1. 38 3 8 3. h1 h h- 0 5 10 15 20 25 cm greenhouse element nitrogen probes assessed rise surface 2

Abstract: This article offers a reflection on the impact of explicit and tacit knowledge on the development of innovations in seven Costa Rican food industry companies that are members of the Costa Rican Chamber of Food Industry (CACIA, in Spanish). This was done with the purpose of deriving implications for the Costa Rican educational system. The research was a qualitative approach, based on the application of semi-structured interviews with officers in each of the companies. The results show that both forms of knowledge play a central role in the achievement of various innovations in each of the organizations. The results also suggest six implications for the education system as a socializing institution and a builder of knowledge and skills for a society that demands innovative people.

ABSTRACT This study was conducted under the qualitative paradigm, employing data collection techniques, description, analysis, and interpretation, with a participatory action and rural participatory diagnostic design. The general objective was to determine the impact of innovation on sustainable agri-food systems. The "working with people" model was followed to engage with farmers and diagnose the advantages, strengths, and challenges they face in implementing innovation policies, specifically in educational innovation, using training and capacity-building methodologies for farmers, support teams, and technical assistance. It was concluded that educational innovation is the central axis to be integrated for the transformation of sustainable and resilient food systems, ensuring food sovereignty. Such innovation enables the development of conservation family farming, with respect for nature, genetic resources, and the cultural identity of rural areas.

RESUMEN El presente trabajo se desarrolló bajo el paradigma cualitativo, con la aplicación de técnicas de recolección de datos, descripción, análisis e interpretación, con un diseño de acción-participativa y diagnostico rural participativo. El objetivo general se desarrolló en función de la determinación del impacto de la innovación en los sistemas agroalimentarios sostenibles. Se siguió el modelo de trabajo con la gente (working with people) para vincularse con los agricultores y de esa forma diagnosticar las ventajas, fortalezas y dificultades que presentan para implementar políticas de innovación, particularizada a la innovación educativa, con metodologías de formación y capacitación a los agricultores, equipos de apoyo y asistencia técnica. Se concluyó que la innovación educativa es el eje central a integrar para la transformación de los sistemas alimentarios sostenibles, resilientes, garantizando la soberanía alimentaria, ya que tal innovación permite el desarrollo de la agricultura familiar de conservación, con respeto a la naturaleza, recursos genéticos y la identidad cultural de las zonas rurales.

Resumen La desnutrición infantil constituye un desafío de gran importancia en el ámbito de la salud pública. El objetivo de la investigación fue evaluar la influencia de los factores sociales y culturales en el estado nutricional en niños menores ecuatorianos de 2 años, en la ciudad de Portoviejo, Provincia de Manabí, durante el año 2023. Se realizó una investigación prospectiva, descriptiva, transversal y observacional. La población pediátrica incluyó 169 menores de dos años, cuyas madres proporcionaron los datos pertinentes. Los factores sociales predominantes fue el nivel educativo del cuidador del niño comprendida entre 7 a 12 años de estudios con la presencia de casos de desnutrición crónica en un 83,9%; además, la limitada contribución financiera del progenitor para la alimentación del infante con casos de desnutrición aguda en un 88,6%. Dentro de los factores culturales, se encontró que los niños con esquema de vacunación incompleto presentaban desnutrición crónica con un 88,7%, la falta de los controles prenatales, al igual que la inasistencia al primer control prenatal antes del quinto mes con casos de desnutrición aguda en un 95,5%; además, se evidenció que la estimulación para la ingesta de alimentos y la falta de práctica de la lactancia materna exclusiva con la presencia de desnutrición crónica en los menores, con un 98,4% y un 96,8%, respectivamente. En este entorno, el estado nutricional de mayor tendencia fue la desnutrición crónica con un 34,3%. Además, se identificó una asociación significativa de relación de dependencia (p<0,05) entre los factores sociales, culturales y el estado nutricional.

Abstract Child malnutrition constitutes a challenge of great importance in the field of public health. The objective of the research was to evaluate the influence of social and cultural factors on the nutritional status in Ecuadorian children under 2 years of age in the city of Portoviejo, Province of Manabí, during the year 2023. A prospective, descriptive, crooss-sectional and observational research was carried. The pediatric population included 169 children under two years of age, whose mothers provided the relevant data. The predominant social factors were the educational level of the child's caregiver, ranging from 7 to 12 years of education, with the presence of cases of chronic malnutrition in 83.9%; in addition, the limited financial contribution of the parent to feeding the infant with cases of acute malnutrition in 88.6%. Within the cultural factors, it was found that children with an incomplete vaccination presented chronic malnutrition with 88.7%, the lack of prenatal check-ups, as well as non-attendance at the first prenatal check-up before the fifth month with cases of malnutrition acute in 95.5%; Furthermore, it was evidenced that the stimulation of food intake and the lack of practice of exclusive breastfeeding with the presence of chronic malnutrition in minors, with 98.4% and 96.8%, respectively. In this environment, the most trending nutritional status was chronic malnutrition with 34.3%. In addition, a significant association of dependency relationship (p<0.05) was identified between social and cultural factors and nutritional status.

ABSTRACT Objective To analyze the impact of Dual Diagnosis on patient’s work capacity and verify if the professional activity sector matters. Dual Diagnosis is defined by the coexistence of an Addiction and another psychiatric disorder. Methodology All patients admitted for inpatient treatment at Alcohol and New Addiction’s Treatment Unit from Lisbon’s Psychiatric Hospital Center, for six months, between 1st November 2021 and 30th April 2022, were selected and screened for sociodemographic and clinical characteristics (age, gender, education level, professional situation, and activity sector at admission as well as main admission diagnosis and other psychiatric comorbidities). Retrospective observative analysis focused on patient’s work capacity was conducted between patients who had been diagnosed with an Addiction Disorder and patients with Dual Diagnosis. Results Our sample had 78 patients and an average age of 51 years. From those, 31 had diagnosis of Addiction Disorder and 47 had Dual Diagnosis. Only 27% patients were still active at admission, with 15% being with temporary incapacity certificate, 41% being unemployed and 17% retired. A significant part of our sample worked in accommodation, transportation, and food services activities (29%), construction sector (19%) and in healthcare, education, and social work activities (17%). The unemployment rates between patients with an Addiction Disorder and Dual Diagnosis were similar. However, 39% of patients with an Addiction Disorder were active while only 19% with Dual Diagnosis were in the same state. Also of interest was that 34% of those with Dual Diagnosis worked in accommodation, transportation, and food services activities. Conclusions These results show that Dual Diagnosis may have a significant impact in the working capacity and suggest that there are important differences between professional activity sectors in patients with or without dual diagnosis.

RESUMO Objetivos Analisar o impacto da Patologia Dual na capacidade de trabalho e verificar se existe relevância com o setor de atividade profissional. A Patologia Dual define-se pela coexistência de uma Adição e de outra patologia psiquiátrica. Metodologia Todos os pacientes internados para tratamento na Unidade de Tratamento para Álcool e Novas Dependências do Centro Hospitalar Psiquiátrico de Lisboa, durante seis meses, entre 1 de novembro de 2021 e 30 de abril de 2022, foram selecionados e avaliados quanto a características sociodemográficas e clínicas (idade, género, nível de educação, situação profissional e setor de atividade aquando da admissão, bem como diagnóstico principal à admissão e outras comorbilidades psiquiátricas). Realizada uma análise observacional retrospetiva focada na capacidade de trabalho dos doentes entre aqueles diagnosticados apenas com uma Adição (com ou sem uso de substância) e doentes com o diagnóstico de Patologia Dual. Resultados A amostra incluiu 78 pacientes com uma idade média de 51 anos. Destes, 31 foram diagnosticados com uma Adição e 47 com Patologia Dual. Apenas 27% dos pacientes estavam com uma situação profissional ativa aquando da admissão hospitalar, com 15% em situação de incapacidade temporária para o trabalho, 41% em situação de desemprego e 17% na reforma. As principais áreas de atividades presentes na amostra pertenciam a três setores, sendo que 29% dos pacientes trabalhava no setor da restauração, hotelaria, transportes e outros serviços de lazer, 19% no setor da construção e 17% no setor da saúde, educação e serviços sociais. As taxas de desemprego presentes entre pacientes diagnosticados com Adição foram semelhantes à dos pacientes diagnosticados com Patologia Dual. No entanto, 39% dos pacientes com Adição encontravam-se com uma situação profissional ativa, enquanto que apenas 19% dos diagnosticados com Patologia Dual estavam profissionalmente ativos. Observamos ainda que 34% dos pacientes com patologia dual trabalhavam no setor da restauração, hotelaria, transportes e outros serviços de lazer. Conclusões Os resultados demonstram que a Patologia Dual pode ter um impacto significativo na capacidade de trabalho da população e sugerem que existem diferenças importantes entre os setores de atividade profissional em pacientes com ou sem o diagnóstico de Patologia Dual, contudo, são necessários estudos mais alargados nesta área.

Abstract This essay explores the convergences and singularities of popular education and Food and Nutrition Education based on biographical fragments of the undergraduate training program in Nutrition of three university professors who established their academic and professional trajectories at these crossroads of knowledge and actions mediated by popular education. Inspired by the autobiographical method, the narratives revealed that the initial indignations with social inequalities were mobilizing the routes in the formative path toward understanding hunger, suffering, and human care. To this end, seeking spaces and opportunities to learn about and experience social work in contexts of vulnerabilities was a decisive factor in their personal and professional constructions, revealing the contradictions of traditional training models and the starting point for the genesis of critical thinking. Thus, clues are offered to understand the interfaces of Popular Education (PE) and Food and Nutrition Education (FNE) in the converging actions around the fight against hunger and the right to food without, however, reducing one to the other when food and Nutrition are projected on the horizon of practices. method suffering care end constructions thinking Thus PE (PE FNE (FNE without however practices

Resumen El artículo expone parte de los resultados del proyecto de investigación «Violencia y endeudamiento: mecanismos que coartan los derechos humanos de personas endeudadas en el sector informal costarricense», desarrollado en la Universidad Estatal a Distancia. Bajo un carácter descriptivo, a partir de la revisión de antecedentes nacionales e internacionales y la participación de seis mujeres, se logra comprender el impacto del endeudamiento informal en la historia de vida de la población participante. Como parte de los hallazgos, las personas participantes evidenciaron una serie de privaciones relacionadas con la educación, empleo formal y conocimientos financieros; a su vez, la figura del crédito informal se destina a gastos regulares requeridos para la reproducción de condiciones de vida (pago de alquiler, alimentación o servicios básicos), con montos catalogados como «micro créditos», sujetos a plazos y condiciones definidos a criterio de la persona prestamista; espacio en el cual, se evidencian mecanismos coercitivos de presión y violación a la integridad de la persona (amenazas, daño físico) para pagar la deuda.

Résumé Cet article expose une partie des résultats du projet de recherche intitulé «Violence et endettement: mécanismes restreignant les droits humains des personnes endettées dans le secteur informel costaricain». Il a été mené à bien à Universidad Estatal a Distancia (l'Université de l’État à Distance), sous un caractère descriptif ainsi qu’à partir de la revue des antécédents nationaux et internationaux et de la participation de six femmes, il est possible de comprendre l'impact de l'endettement informel dans l'histoire de vie de la population participant à l'étude. Parmi les découvertes, les participants ont montré une série de privations liées à l'éducation, à l'emploi formel et aux connaissances financières. Parallèlement, la pratique du crédit informel est destinée à des dépenses régulières nécessaires à la reproduction des conditions de vie (loyer, alimentation ou services de base), avec des montants qualifiés de «microcrédits», soumis à des échéances et des conditions définies selon le critère du prêteur. Dans cet espace, des mécanismes coercitifs de pression et de violation de l'intégrité de la personne (menaces, dommages physiques) pour rembourser la dette sont mis en évidence.

Abstract The article presents part of the results from the research project titled 'Violence and Indebtedness: Mechanisms Restricting the Human Rights of Indebted Individuals in the Costa Rican Informal Sector,' conducted at the Universidad Estatal a Distancia (Distance State University). In a descriptive manner, drawing on a review of national and international precedents and the participation of six women, the impact of informal indebtedness on the life stories of the participating population is understood. Among the findings, participants revealed a series of deprivations related to education, formal employment, and financial knowledge. Simultaneously, informal credit was used for regular expenses necessary for the reproduction of living conditions (rent, food, or basic services), with amounts categorized as 'micro-credits,' subject to terms and conditions defined at the discretion of the lender. Within this context, coercive mechanisms of pressure and violation of personal integrity (threats, physical harm) are evident in the process of debt repayment.

Abstract Objective: Carried out a structural analysis to identify the variables that intervene in the strengthening of the short food supply chains in the Metropolitan Area of Xalapa, Veracruz, Mexico (ZMX). Methodology: A descriptive and correlational research was carried out, with a mixed approach, semi-structured interviews Results: The SFSC identified in the ZMX were characterized according to the type of proximity, temporality, type of production, size, form of organization, validity, type of initiative, the origin of the products, pricing strategy, and communication strategy with the consumers. In addition, it was identified that the key variables for the strengthening of the CCC in the ZMX are agroecological production, consumer education, governance, and diversity in the supply of local products. Limitations: The particularities of the context and the social actors generate constant changes in the development of the SFSC, for which reason the research registers a specific time. Conclusions: The SFSC plays a relevant role in territorial development, mainly for the link between the urban and peri-urban areas of the ZMX. Multi-stakeholder participation is important for its strengthening, and this can be linked to public program strategies that facilitate the creation and consolidation of SFSC in the region.

Metodología: Investigación de tipo descriptiva y correlacional, con un enfoque mixto, entrevistas semiestructuradas Resultados: Se caracterizaron los CCC identificados en la ZMX de acuerdo con el tipo de proximidad, producción e iniciativa, temporalidad, tamaño, forma de organización, vigencia, procedencia de los productos, estrategia de fijación de precios y estrategia de comunicación con los consumidores. Se identificó que las variables clave para el fortalecimiento de los CCC en la ZMX son producción agroecológica, educación al consumidor, gobernanza y diversidad en la oferta de productos locales. Limitaciones: Las particularidades del contexto y de los actores sociales, generan cambios constantes en el desarrollo de los CCC, por lo que la investigación registra un periodo específico de tiempo. Conclusiones: Los CCC juegan un rol relevante en el desarrollo territorial, principalmente para la vinculación entre las áreas urbanas y periurbanas de la ZMX. La participación multiactoral es importante para su fortalecimiento y esta puede estar vinculada con estrategias de programas públicos que faciliten la creación y afianzamiento de los CCC en la región.

ABSTRACT Academic stress is suffered by secondary and higher education students, whose stressors are related to the academic demands they will face during their school/university activities. The objective of the present study was to describe and compare the level of academic stress among physical education pedagogy students in Chile according to sex and year of study. For this purpose, the SISCO Academic Stress Inventory was applied to a sample of 286 students from two universities in Santiago, Chile. The results reveal mild stress levels in the sample, with higher levels in women and during the last years of the teaching degree. The main stressful situation is not understanding the topics addressed in class. The most common physical reaction to stress is scratching and biting nails, the most common psychological reaction to stress is concentration problems, and the most common behavioural reaction to stress is to increase or decrease food consumption. Finally, assertive skills are the most used strategy to face stressful situations. More research is recommended with samples from other universities and other teaching programmes to delve deeper into this topic.

RESUMEN El estrés académico es aquel que padece el alumnado de educación secundaria y superior, cuyas fuentes estresoras se relacionan con las exigencias académicas a las que se verán sometidos durante sus actividades escolares/universitarias. El objetivo del presente estudio fue describir y comparar el nivel de estrés académicos entre el estudiantado de pedagogía en educación física de Chile, según sexo y año de carrera. Para ello se aplicó el Inventario SISCO de estrés académico a una muestra de 286 estudiantes de dos universidades de Santiago, Chile. Los resultados revelan niveles medios de estrés en la muestra, con mayores niveles en las mujeres, y en los últimos años de carrera. La principal situación estresora es no entender los temas que se abordan en la clase; mientras que la reacción física más común frente al estrés es rascarse, morderse las uñas, la reacción psicológica más común frente al estrés son los problemas de concentración, en tanto que la reacción comportamental más común frente al estrés es aumentar o disminuir el consumo de alimentos. Finalmente, la habilidad asertiva es la estrategia más utilizada para enfrentar situaciones de estrés. Se recomiendan más investigaciones con muestras de otras universidades y otras carreras de pedagogía para profundizar en este tema.

The number of people on Earth and human activities are currently taking on frightening proportions with far-reaching consequences for our planet, its biodiversity and ultimately the human race itself. Ten thousand years ago, humans represented 1% of the total biomass of all land vertebrates. The rest was made up by wild animals. Currently, humans, livestock and pets make up 99% of terrestrial vertebrate biomass, while wild animals represent only 1%. It took millennia for the human population to reach the 1 billion mark and that only by 1890. By 1960, however, the world population had grown to 3 billion. Today there are 8 billion people living on our planet. According to Population Matters, the world population will be approximately 10,4 billion by the end of this century, despite the gradual decline in the growth rate in some countries. There is only a 23% chance that the total population growth rate will tail off before 2100. The population of the 47 least developed countries is likely to triple between 2017 and 2100 to around 3 billion. There are currently 62 million people in South Africa. About 67,9% of our population (in 2021) live in urban areas. The South African population grew by 0,87% in 2023. The fertility rate is 2,30 (2023). It is estimated that by 2050 75,5 million people will be living in South Africa, with 8 out of every 10 people living in urban areas, which would significantly increase the pressure on infrastructure. The Global Footprint Network states that humans currently use the resources of 1,75 Earths. If the situation does not improve, by 2050 we would need the equivalent of three Earths to survive. More than 4 billion people will have little or no water by 2050, and South Africa even now has been classified as a "water-stressed" country. Medical science is continually contributing to more babies surviving their entry into the world and to our living increasingly longer. Life expectancy has risen from 46 years in 1950 to 73,2 years in 2023. By 2050 it will be 77 years. What can be done? Empowerment of women is important. Population growth can be curbed to a reasonable extent by giving more girls access to education. This certainly does not mean that girls or women alone should be held responsible for the current population growth, but much more will have to be done about sex education, women's rights will have to be actively promoted and there will have to be better provision and use of contraceptives. Obviously, these issues should be approached and handled with due caution. In this regard, countries such as Thailand and South Korea have, in the recent past, proved that good education may result in lower birth rates. In Africa, women with no education have an average of 5,4 children; women who completed high school an average of 2,7 children and women with tertiary education an average of 2.2. In Nigeria, every year of school attendance by girls cuts the birth rate by a tenth. In addition, intensified efforts to reform economies and societies should be considered. For the sake of the survival of the human species and the sustainability of the Earth, ecological and economic justice and the empowerment ofwomen have to be encouraged. The Millennium Project - a global participatory think tank that was founded in 1996 under the auspices of the American Council for the United Nations University, but which became independent in 2009 and has since grown into a global network of institutions and individuals - aims to improve humankind's prospects for a better future. It recommends, among other things, the following: • Support a policy aimed at improving the survival of children, responsible family planning and educational opportunities for (especially) girls. • Improve methods that will ensure skills and employment opportunities for young people, as well as care and services for the elderly. • Implement the UN's urban agenda. • Create enough smart cities where citizens with urban intelligence can help in eco-smart ways with the necessary improvements in the city. • Increase training in resilience, and improve disaster prediction and management. • Provide guidance for people about urban ecology. • Intensify research and development in saltwater agriculture (halophytes or salt plants) on coastlines to produce food for humans and animals, biofuel and pulp for the paper industry, and to absorb carbon dioxide (CO2). This will ease the pressure on freshwater agriculture. • Improve agricultural and irrigation management. • Invest in precision agriculture and aquaculture. • Reduce food losses from the "farm to the mouth" (one third or 1,3 billion tons of agricultural production is wasted in this way every year). • Establish seaweed to restore wild fish populations along coastlines. The World Bank estimates that 90% of marine life is completely depleted. • Expand the production of insects for animal feed and human diets (insects have a low environmental impact, and 2 billion people already supplement their diet with insects today). • Encourage vegetarianism. Although there are more ways to address these important global challenges, responsible family planning remains one of the most important. This is an extremely sensitive issue for many people (especially in Africa), but if it is not promoted in a humane, informed and responsible way, the sustainability of life on our planet will increasingly come under tremendous pressure in various respects.

Die aantal mense op aarde en hulle/ons aktiwiteite neem tans skrikwekkende afmetings aan met wydlopende gevolge vir ons planeet, biodiversiteit en uiteindelik onsself. Die moderne mens het sy teenwoordigheid op die aarde en die benutting van hulpbronne baie lank as sy onaantasbare reg gesien. Die huidige uitwerking van byvoorbeeld bevolkingsgroei en besoedeling versteur die aarde se natuurlike ritme in so 'n mate dat ons nou nie meer op 'n kitsoplossing kan hoop nie. Die mens se getalle neem teen so 'n tempo toe dat dit nie net nadelig vir die planeet is nie, maar ook vir die mensdom self. Wat kan gedoen word? Bemagtiging van vroue speel 'n belangrike rol. Dit beteken beslis nie dat meisies en vroue alleen vir die huidige bevolkingsgroei verantwoordelik gehou moet word nie. Die bevolkingsgroei kan egter in 'n redelike mate vertraag word deur veral meer meisies toegang tot onderwys en opleiding te gee - asook hul lewensomstandighede te verbeter. Ook sal daar heelwat meer aan seksopvoeding gedoen moet word, vroueregte sal daadwerklik bevorder moet word en daar sal beter voorsiening en gebruik van voorbehoedmiddels moet wees. Uiteraard moet hierdie kwessies met die nodige omsigtigheid benader en hanteer word. In hierdie verband kan onder andere Thailand en Suid-Korea genoem word wat in die onlangse verlede bewys het dat goeie onderwys geboortesyfers laat daal. In Afrika het vroue wat geen onderwys ontvang nie, gemiddeld 5,4 kinders; vroue wat hoërskool voltooi het gemiddeld 2,7 kinders en vroue wat tersiêre studie deurloop het, gemiddeld 2,2 kinders. In Nigerië sny elke jaar wat meisies skool bywoon, die geboortesyfer met 'n tiende. Hiermee saam sal daar ook verskerpte pogings moet wees om ekonomieë en samelewings te hervorm. Ter wille van die mens se voortbestaan en die volhoubaarheid van lewe op aarde moet ekologiese en ekonomiese geregtigheid, en die bemagtiging van vroue aangemoedig word.
