SUSTAINABLE WATER RESOURCE MANAGEMENT IN NIGERIA: CHALLENGES, INTEGRATED WATER RESOURCE MANAGEMENT IMPLEMENTATION, AND NATIONAL DEVELOPMENT
Authors: Martins Grace , Ehinmentan Bidemi , Mafimisebi Peter , America Alex , Gbadero Gideon
Published: October 2024

Water resource management is essential for societal advancement, as water supports various human activities, including domestic, agricultural, industrial, and recreational uses. In Nigeria, the challenges of managing water resources are exacerbated by uneven distribution, population growth, and inadequate infrastructure. Despite Nigeria's significant renewable freshwater resources, only 69% of the population has access to basic water services, highlighting the nation's inefficiencies in water governance. The Integrated Water Resources Management (IWRM) approach offers a framework to address these challenges by promoting sustainable water use, stakeholder involvement, and the protection of ecosystems. However, Nigeria's implementation of IWRM faces hurdles, such as weak governance, conflicting institutional interests, and insufficient stakeholder engagement. This study examines the historical and current state of water resource management in Nigeria, its impact on national development, and the potential benefits of adopting IWRM. It explores lessons learned from global IWRM practices and provides recommendations for improving water governance to achieve the SDGs, particularly SDG 6 (clean water and sanitation) and SDG 11 (sustainable cities and communities). Addressing these challenges will require stronger institutional frameworks, cost recovery mechanisms, and the integration of local insights with international best practices.

OLD city space from the perspective of multi community — Take a floating population community in H city as an example
Authors: Gao Yunhong , Yin Haijie
Published: October 2024

Taking the specific practice of an old city space as an example, this paper distinguishes the positions and practices of three actors in the space: Urban planners, managers and ordinary citizens hold an extreme modernist position, firmly believing that the old urban space needs to be removed and transformed into a new urban order; Citizens living in the old city space hold a more complex and contradictory position. As the bottom group of the city, they pay attention to the exchange value of community space, but it is difficult to change their living conditions, while maintaining the exclusion of the old city space and the floating population; The floating population builds the old urban space into a space for production and life, making it a "settled community" entering the city. Finally, the diverse position and practice of the old city space show its significance of urbanization and its important role in the construction of urban diversity.

URBAN service diversity and labor mobility — Analysis Based on "meituan.com" big data and micro survey of floating population
Authors: Zhang Wenwu , Yu Yongze
Published: October 2024

In the context of the new era, people's pursuit of a better life is becoming more and more prominent. The diversity and welfare of urban services will become an important support for attracting labor and optimizing talent structure. This paper uses the "meituan.com" life service classification and the 2017 China floating population dynamic monitoring survey (CMDS) data to study the impact of urban service diversity on labor mobility. The results show that the diversity of urban services will significantly reduce the willingness of migrant population to move out. For every 1% increase in the diversity of service categories, the average probability of labor migration will be reduced by about 3.5% 23%; The impact of urban service diversity has group differences. Younger and highly skilled groups are more sensitive, and the marginal effect can reach 4.5% 62% and 4 03%. Considering the adjustment effect and regional heterogeneity, the expansion analysis further found that the level of urban informatization and marketization has a positive amplification effect on the diversity of service categories to attract and retain talents, especially in the eastern region and large cities with a population of more than 5 million. This study provides policy enlightenment for urban talent attraction and labor competition.
The impact of cultural diversity on urban housing prices in China
Authors: Zhuang Yun , Wang Wenwen
Published: October 2024

Using the commercial housing price data of 254 cities at prefecture level and above in China, this paper measures the cultural diversity by the diversity of Chinese dialects, and studies the impact of regional culture represented by dialects on urban housing prices. The research shows that after controlling the economic development level of the city, the urban ecological environment and other factors, the cultural diversity measured by dialect types has a significant negative impact on the price of urban commercial housing, that is, the more diverse the culture, the lower the house price, and the cultural diversity will restrain the house price by hindering the inflow of local population.
Return to spatial differentiation and respect life diversity–Two core supporting points to avoid the deviation of urban fine governance
Authors: Han Fuguo
Published: October 2024

Modern urban governance emphasizes the precise governance of the “short board” of urban governance, forming a mechanism of fine governance. In view of the historical basis and realistic structure of the differentiation of physical space at the block level and the diversity of life at the community level in modern cities, the short board of urban governance should be confirmed and solved through democratic participation based on the context of spatial differentiation and diversity of life, rather than through simple administrative urban planning, so as to form a corresponding structure consistent with rigid urban management. The vitality of a city lies in the construction of differentiated block space and diversified community autonomy. Therefore, the urban path of fine governance is fine governance based on public recognition. It should include the establishment of the concept of spatial differentiation and diversity of life, the construction of democratic relations among modern urban governance subjects, the transformation of urban planning to community planning, and the avoidance of destructive renewal and one-way material construction, go beyond the sports regulation of urban issues and apply the big data technology in modern urban governance.
Discussion on the biodiversity protection planning methods based on urban–regional scale
Authors: Yue Bangrui , Kang Shilei , Jiang Chang
Published: October 2024

This paper explores the relationship between the spatial scale and biodiversity protection level and thinks that under the specifi c urban-region scale, landscape diversity is the key level to the macroscopic protection of biodiversity. Based on the systematicness and the otherness of urban–regional environment and the biologic fl ow and process, the protection pattern of biodiversity within urban–regional scale should be established. The author holds that seeking the “optimal landscape pattern”is one of the core missions of biodiversity protection planning. Based on that, the paper summarizes the two types of city space and their biodiversity planning and design in two ways: first, the”Urban-rural landscape pattern optimization approach”specific to the space of city matrix, which includes “agglomeration segregation”,”landscape”, “green infrastructure”, three models and five pattern optimization strategies; second,  the “Nature reserve approach” specific to the space of natural matrix, which includes”reserve circle”and”protected area network”two modes and six reserve design principles.

The protection planning of small and micro habitats in urban fringe areas: Enlightenment from the management of high natural value farmland in the EU to the maintenance of bio-diversity in urban areas in China
Authors: Tang Xizi
Published: October 2024

The habitat unit in urban fringe is an important link to support regional biodiversity; due to the influence of urban system and agricultural system, most of them are semi natural, appeared with diverse types, small patches, scattered layout, and generally relying on low intensity farming activities. Export-oriented expansion of urban construction land and intensive agricultural production are prone to reduce the scale and quality of semi natural habitats in urban fringe areas; and the existing measures cannot effectively protect them. High natural value farmland management is an effective measure of the EU to protect semi-natural habitats related to agriculture and maintain regional biodiversity. Through combing the main points of high natural value farmland such as type definition, evaluation, identification, maintenance management, etc., this paper proposes the suggestions for optimization of small and micro semi-natural habitat protection in China: (1) strengthening the recognition of the value of small and microhabitats and related land use; (2) identifying small and micro-habitats that are conducive to the maintenance of biodiversity, and incorporating them in the overall protection of regional network; (3) combining the rigidity and flexibility of land use control, with the consideration of complex function demands; (4) Converging with the existing statutory planning to enhance the protection efficiency of small and micro habitats.
Dialect diversity and market integration: From the perspective of city circle*
Authors: Ding Congming , Ji Zhenlin , Lei Yu , Liang Zhenqiao
Published: October 2024

China, as a transitional economy, faces a high level of market segmentation among administrative regions, which lowers the efficiency of resource allocation and the total factor productivity (TFP) rate. The literature has focused on the negative effects of local protectionism and administrative division on the formation of market integration in the economic growth process. However, considering that administrative districts such as prefectures usually overlap with cultural regions in China, the effects of local protectionism and administrative division on market segmentation may be overestimated because cultural diversity may also be negatively related to market integration. More importantly, diversity of dialect tends to increase the cost of communication, making it a barrier to labor migration and decreasing the level of generalized trustamong people. As a result, it may have adverse effects on the market integration process.
Industry related diversity, unrelated diversity And urban aggregate employment creation
Authors: He Xiangmin , Lai Yongjian
Published: October 2024

Employment is the biggest livelihood of the people. What kind of industrial structure is more conducive to employment creation is an important issue for the government to consider when adjusting the industrial structure. Using enterprise and city data, using a spatial dynamic panel model that takes into account both the dynamic change of dependent variables and the spatial spillover effect, and can overcome the endogenous problem between variables, this paper examines the impact of industry-related diversity and unrelated diversity on urban aggregate employment creation. The study finds that both types of diversity are conducive to urban aggregate employment creation, but the role of related diversity is more prominent in comparison. Urban heterogeneity plays an important role in regulating the employment creation effect of industrial diversity. Among them, urban absorptive capacity strengthens the employment creation effect of the two types of industrial diversity, and is more conducive to promoting the employment creation effect of related diversity. However, the level of Urban Entrepreneurship is only positive for the employment creation effect of unrelated diversity.

Published: October 2024

In a multicultural country such as Colombia, ethnoeducation is an important component of health education, because it promotes the quality of life of ethnic minorities based on the community's potential, practices, habits, experiences and approaches that promote overall health awareness. The purpose of this article is to perform a narrative review on the background of ethnoeducation and its impact on health. The development of inter-cultural skills among students in health fields would enable the future professional to perform their roles with adequate cultural relevance, respecting the values, traditions and history of the communities. Topics discussed: Worldwide, ethnoeducation has been highly relevant, and some international organizations have worked on its implementation for decades. In Colombia, several legal and regulatory instruments have been developed to implement ethnoeducation. However, close to 86 % of the ethnic populations do not have access to education in accordance with the established principles. The importance of ethnoeducation has been highlighted in several countries in that it has achieved positive results such as a reduction of morbidity and mortality through educational activities that promote health and help prevent diseases. To achieve this, it is essential that the planned activities be integrated into the communities' cultural perceptions. Conclusion: Although local, national and international guidelines have been established, ethnoeducation continues to be a challenge. It is necessary to increase efforts in order for ethnoeducation to achieve the objectives that have been set out from a theoretical perspective.

Maximizing the production of electricity from PEMFC is crucial to maintaining effectiveness. This research article thoroughly analyzes a research study using a strategy known as MPPT, or maximum power point tracking that uses the neuro-fuzzy method for PEMFC operating under diverse temperatures, pressures, and joining constraints. The neuro-fuzzy controller cleverly regulates the point of maximal operation of a hydrogen fuel cell system, allowing exact adherence to the highest possible power scale. According to simulation results, the neuro-fuzzy MPPT technique improves PEMFC validity across a wide range of operating scenarios.
What turns a bicycle street into a street for cyclists? A multimodal study on subjective safety of infrastructure measures on bicycle streets using an approach in virtual reality
Authors: Schwarzkopf Marc , Dettmann André , Bullinger Angelika C.
Published: October 2024

In an increasingly urban and sustainable transportation-focused world, cycling emerges as a key environmentally friendly and health-promoting mode of travel. This paper addresses the gap in understanding cyclists' subjective safety, particularly in relation to bicycle streets in Germany. Utilizing a multimodal approach, two studies were conducted: an online questionnaire (Study I) and a Virtual Reality (VR) evaluation (Study II), focusing on the Reichenhainer Straße in Chemnitz. Study I involved N = 182 participants who regularly used the bicycle street. The questionnaire covered various aspects including mobility behavior, cycling experience, and subjective safety, using a 6-point Likert scale. Infrastructure characteristics were represented through images. Results showed that participants generally felt safe on the bicycle street, with key factors being the lane width and restrictions on motorized traffic. Study II, a pioneering effort in using VR and stereoscopic 360° images for evaluating cycling infrastructure safety, involved N = 32 participants. It provided a realistic evaluation of infrastructure elements and their impact on perceived safety. The study revealed significant differences in safety ratings based on the presence of cars and cyclists' experience levels. The use of VR allowed for a focused examination of infrastructure characteristics and their perceived safety, highlighting potential areas for improvement. Both studies demonstrated consistent results, underscoring the subjective safety of the Reichenhainer Straße, which was perceived as safer than the average bike-accessible infrastructure in Chemnitz. The VR method proved effective for detailed evaluation of subjective safety, independent of participants' familiarity with the specific infrastructure. This approach offers a structured, controlled, and resource-efficient way to evaluate cycling infrastructure under laboratory conditions. In conclusion, the findings align with existing literature and emphasize the importance of lane width and reduced motorized traffic for cyclists' safety. The innovative VR method, while still developing, offers promising implications for future citizen participation initiatives and infrastructure planning projects, enabling efficient post-completion evaluations of subjective safety. Such practices are rare in German planning offices, highlighting the paper's contribution to enhancing urban cycling infrastructure planning and safety assessment.

The effect of de-escalation training on aggression incidents and the use of restraints in females in forensic psychiatry

De-escalation is recommended as the first response to potential aggression within forensic psychiatry. To imbed de-escalating techniques in daily clinical practice, education and training of the staff is essential. Various de-escalation training programmes have been developed, but research on the effectiveness of these training programmes in the forensic psychiatry is scarce. Previous research rarely focused on the impact of the training on the prevalence of aggressive behaviour and the use of coercive measures within forensic psychiatric clinics.

Therefore, the aim of the current study is to measure the effect of a de-escalation training programme on aggressive incidents and the use of seclusion. A pre-post measurement design with paired data was set up within a Flemish high-security forensic psychiatric unit, that provides treatment for female forensic psychiatric patients.

No significant differences were found in the number of aggressive incidents between the pre- and post-measurement period, not even when the type of aggression was taken into account. However, there was a decrease in the severity of verbal aggression. Although, no significant differences were found in the number of seclusions with and without restraint between the pre- and post-measurement period, the mean number of seclusion hours did decrease significantly.

The findings of the current study were not consistent with those of previous research. Possible explanations for these differences are variation in the implementation process of the de-escalation training, in the contextual factors and in the methodology used. Decreasing the prevalence of aggressive incidents and the use of seclusion by using de-escalating techniques is a long-term goal and asks a lot of reflection and further practice. Future research should focus on the factors that facilitate or complicate the impact of a de-escalation training. In this way, the possible added value of de-escalation in clinical practice can be further scientifically supported.

Possession of child sexual abuse material: Differences in sexual self-regulation problems between a judicial and a self-reporting group

People who have possessed child abuse material (CSAM) constitute a specific group of sex offenders, who can be distinguished from both those who have committed child abuse and the ‘mixed’ group, who are known to have committed both crimes. This specific group is in itself a heterogeneous group. Much research on this group relates to people who have already come into contact with the justice system and little is known about people who come forward voluntarily. The current study does include the latter group and investigates possible differences in sexual problems between those who were arrested for looking at CSAM (the judicial group) and those who sought help themselves without judicial intervention (the self-reporting group). Pedophilic or hebephilic interests, other paraphilic interests, sexual preoccupation and sexual coping were compared between the two groups by means of the VSP and HBI019 self-report questionnaires. The results showed that the self-reporting group experienced more problems on all measured dimensions than the judicial group. The results are relevant to the treatment of these groups.

Working with victims during offender treatment: Restoration within forensic psychiatry from the perspective of systemic counselors

This contribution examines the practice of contact with victims within forensic psychiatric treatment from the perspective of the forensic social worker who supervises the network of an inpatient. Both the direct contact between inpatient and victim and the indirect contact between network supervisor and victim are included. This professional contribution examines the specific role of a forensic network supervisor and describes what is possible in contact with victims and how this is achieved on the basis of three themes, namely 1) the work and vision that network supervisors have on their role, 2) the chain partners and the cooperation therewith, and 3) the various procedures that exist and how they are handled. For each theme, the substantive relevance in relation to contact with victims is discussed, as well as the opportunities and possible difficulties. This study shows that network supervisors experience a tension between the interests of inpatients and victims, whereby the importance of good chain cooperation is clearly endorsed. Furthermore, not all network supervisors act the same in equal cases, which can create inequality for victims. A more uniform job description and task interpretation could overcome this. Finally, this study shows that network supervisors consider it to be important that victims have a voice and are involved in important moments during forensic treatment.
THE SOCIAL DIMENSIONS OF CLIMATE CHANGE IN VIET NAM

Published: October 2024

Global trends in inequality and climate change are closely related. The poorest and most vulnerable individuals suffer the worst effects of climate change while making the smallest contributions to the situation. Millions of people who are vulnerable are being hit disproportionately hard by the effects of climate change, including extreme weather, health issues, food, water, and livelihood security, migration and forced displacement, loss of cultural identity, and other threats. Children, people with disabilities, ethnic minorities, older people, and other socially marginalized groups are some social groups that are particularly vulnerable to crises. Their geographic locations, financial, socioeconomic, cultural, and gender statuses, as well as their access to resources, services, decision-making authority, and justice, are the core reasons of their vulnerability. The paper presents some of the social dimensions of climate change in Viet Nam, including its impacts on migration, various vulnerable subjects, human rights, health, and businesses. Comments, discussions, and suggestions have also been provided in this paper.
POST-EL-NIÑO WEAKENING OF COASTAL UPWELLING AND ITS ECOLOGICAL IMPACTS IN THE SOUTH-CENTRAL VIET NAM REGION
Authors: Trần Thị Tân  , Tran Van Chung
Published: October 2024

Upwelling that occurs in the summer offshore of South-Central Viet Nam in the South China Sea (SCS) also known as the East Viet Nam Sea (EVS), is one of the region’s key dynamic processes. The weakening of upwelling phenomena during post-El-Niño events and their ecological responses were studied based on a reanalysis dataset derived from the HYCOM/NCODA system, coupled with a local Finite Element Model (FEM) and observed data. Long-term warming, along with orographic and wind factors, play significant roles in the formation and weakening of upwelling phenomena during normal and post-El-Niño episodes, respectively. The weakening of upwelling during post-El-Niño periods is reflected by: Extreme weakening of wind forcing and Ekman pumping; a northward shift of the cold-saline tongue and current dipole, with a limited eastward extent; dominance of northward circulation in the surface layer and westward circulation in deeper layers; and the formation of a homogeneous surface thermohaline layer of about 50 meters thick, with a thermo-halocline layer at 50-60 meters depth. These abrupt changes strongly influenced the ecological characteristics of the upwelling area. Coral bleaching during the summers of 2010 and 2016, as well as anomalous distributions of chlorophyll-a (Chl-a) in the surface layer in 1998, 2003, 2010, and 2016, were concrete indicators of the ecological responses of Viet Nam's coastal upwelling waters in post-El-Niño years. Detailed intra-seasonal variations of temperature during the summer showed a warming of the waters, leading to coral bleaching and abnormal Chl-a levels during post-El-Niño years. Organisms in this region struggled to adapt to these rapid environmental changes, leading to a potential reduction in living resources.

Published: October 2024

Urbanization often comes with flooding problems. The objective and subjective reasons why this situation persists and becomes increasingly serious are climate change and the concretization process. Currently, many studies have proposed solutions to forecast and warn of rain and tide causing urban flooding or methods to reduce flooding with sustainable green buildings. However, these solutions are all built on the old urban foundation, so flooding continues and the effectiveness of flood reduction is not high. In this article, the authors research the new urban area of Nam Can Tho, Cai Rang district, Can Tho City. This area is in the process of planning for infrastructure construction, so initial solutions have been proposed. Preventing flood risks caused by uncontrolled and unsynchronized urbanization is extremely necessary.

Osteoarthritis (OA) is a joint disease affecting articular cartilage, menisci, and other joint components. The main objective of this study was to investigate structural and biochemical changes in the medial and lateral menisci of Thai OA patients. Histologically, the bone marrow-like structure was mainly observed at the posterior horn of both medial and lateral menisci. The numbers of meniscal cells were significantly lower at the posterior and anterior horns of the medial and menisci, respectively. Cells at the posterior horn of the medial meniscus were significantly hypertrophied. A decrease in proteoglycan was observed mainly at the posterior horn of both medial and lateral menisci, while collagen fibers markedly increased at the posterior horn of the medial meniscus. Moreover, apoptotic cells were significantly higher in numbers at the posterior and anterior horns of the lateral and medial menisci respectively. The results revealed that the pathology of OA occurred mostly at the posterior horn of the medial meniscus.

Authors: Peanpailoon Chainarong , Tongmual Noppakun , Nasinprom Nipa
Published: October 2024

This study evaluates the comparative efficiency of Stratified Folded ranked set sampling (SFRSS) in estimating the population mean against three other sampling methods: Simple Random Sampling (SRS), Stratified Simple Random Sampling (SSRS), and Random Sampling (RSS). The analysis spans various probability distributions, Exp(1), Geo(0.5), Gamma, Weibull, Log N(0,1), CHI(1). The results show that SFRSS outperforms or remains competitive with the other sampling methods, especially in simpler conditions (r=2), across a wide range of distributions. For instance, in the Exponential and Geometric distributions, SFRSS demonstrates superior efficiency at r=2, indicating its effectiveness in less complex scenarios. Similarly, for the Gamma and Weibull distributions, SFRSS maintains high efficiency at r=2, showcasing its adaptability and robustness in various conditions. Notably, in the Log-Normal distribution at r=5, SFRSS’s efficiency dramatically improves against SSRS, suggesting its particular suitability for skewed data under certain conditions. Additionally, SFRSS exhibits exceptional efficiency in the Chi-Square distribution at r=2, underscoring its effectiveness across diverse statistical landscapes. However, at the more complex condition (r=5), although the efficiency of SFRSS generally decreases, it still competes closely with SRSS and outperforms SSRS in certain cases, retaining its relevance and demonstrating a degree of adaptability to complex scenarios. This comprehensive analysis highlights the importance of selecting appropriate sampling strategies based on the study’s distribution characteristics and conditions. SFRSS emerges as a highly efficient method for estimating population means, particularly in less complex scenarios, and remains a competitive choice in more demanding conditions. The findings underscore the potential of SFRSS in optimizing estimation accuracy across various statistical distributions and study designs, affirming its value in statistical research and applications.

A Gestão de Pessoas e o Clima Organizacional são dois pilares cruciais que moldam não apenas o ambiente de trabalho dos servidores públicos, mas também a eficiência e a eficácia das políticas e serviços governamentais. Assim o objetivo geral deste estudo é refletir sobre a importância da gestão de pessoas e do clima organizacional na gestão pública. A metodologia é a abordagem qualitativa e técnica utiliza é análise de conteúdo. Os resultados refletem sobre a importância das práticas de gestão de pessoas e o clima Organizacional nas Instituições Públicas que é uma ocorrência bastante discutida na academia trazendo insights para melhorar a eficiência e a eficácia das empresas. Assim as limitações do estudo foi o fato de ser teórico e as sugestões estudos futuros aplicar pesquisas de clima organizacional em distintos setores municipais, estaduais e federais buscando evidenciar as diferencias e semelhanças que existem nas distintas esferas públicas.

O objetivo deste estudo foi utilizar técnicas de ondas acústicas para determinar de forma não destrutiva as propriedades dos vidros de janela com diferentes acabamentos superficiais. Para isso, foi inicialmente utilizado um sistema eletrônico de emissão e detecção de ondas ultrassônicas com transdutores piezelétricos de 125 kHz, e ferramentas computacionais tais como MATLAB e Origin. Como resultado, foi constatado que a morfologia da superfície dos vidros pode reduzir as propriedades elásticas, bem como diminuir a capacidade de expansão térmica, resistência ao choque térmico e dureza. Estas propriedades foram relacionadas com sinais acústicos propagados nos vidros por meio de impactos gerados com uma esfera de aço em queda livre. Estes impactos excitam grupos de frequências específicos para cada vidro que podem ser identificados com a técnica da Transformada Rápida de Fourier (FFT).
Determinação da incerteza de medição no ensaio de módulo resiliente de brita graduada simples

A medição de uma grandeza física deve estar associada a alguma indicação da qualidade dos resultados obtidos, visto que há incertezas envolvidas nos diversos tipos de ensaios de laboratório, sejam relacionadas às falhas procedimentais, erros humanos ou limitações inerentes aos instrumentos de medição utilizados. Em ensaios de laboratório, essas incertezas podem comprometer a precisão dos resultados, tornando necessário um processo rigoroso de avaliação e quantificação das incertezas. O cálculo das incertezas de medição determina o grau de confiabilidade dos resultados dos ensaios, pois sem essa indicação não é possível avaliar de forma precisa a exatidão dos resultados obtidos ou realizar comparações consistentes entre diferentes resultados experimentais ou valores de referência. Nesse contexto, este estudo verificou que a incerteza expandida associada ao cálculo do módulo resiliente em amostras de brita graduada simples de um trecho da obra de melhoria da capacidade e duplicação da rodovia federal BR-116/RS variou de 0,23% a 0,82%, o que evidencia uma variação aceitável considerando as complexidades envolvidas no ensaio triaxial dinâmico. Essa verificação é muito importante porque o módulo resiliente é um parâmetro essencial na estimativa das tensões e deformações do pavimento referente à ação do tráfego, visto que representa a capacidade da camada do pavimento de resistir à deformação permanente sob cargas repetidas.

O milho tem a luz solar como fator fundamental para desenvolvimento da cultura, onde 90% da matéria seca é produzida pela fotossíntese, além de ser altamente exigente em nitrogênio, o que pode limitar o desenvolvimento e causar baixa qualidade e baixo rendimento dos grãos. O trabalho teve por objetivo avaliar a ocorrência da luz difusa em estádios fenológicos e seu impacto nas características morfoagronômicas da planta de milho. O experimento foi montado em um delineamento em blocos casualizados com 5 repetições e 5 tratamentos: T1) testemunha; T2) V6-V9; T3) V10-VT; T4) VT-R2; e T5) R3-R6, sendo que cada um foi submetido ao sombreamento de 50% simulando a luz difusa, sendo metade com subparcelas de com 1 ou 2 adubações de cobertura. As avaliações experimentais foram: altura da planta e inserção; diâmetro da espiga e do colmo; tamanho da espiga; temperatura das folhas; clorofila; número de fileiras e grãos; teor de água; e produtividade. Interpretando os resultados estatísticos, pode-se concluir que a ocorrência da luz difusa pode interferir negativamente em algumas características morfoagronômicas da planta de milho; o sombreamento interfere na altura da inserção da espiga e no diâmetro da espiga quando ocorre de V6-VT; o teor de clorofila reduziu o impacto do sombreamento no estádio de R1-R3, junto com a aplicação de subparcelas de nitrogênio; apesar da produtividade não apresentar diferença significativa, a ocorrência da luz difusa mostra uma tendência de redução.
