Correlation of Plantation Area and Palm Oil Production in Sumatra and Kalimantan Regions

This study aims to analyze the correlation between the area of oil palm plantations and oil palm production in Indonesia, especially in the Sumatra and Kalimantan regions which are the centers of oil palm plantation distribution. Data collection using secondary data from the Central Statistics Agency (BPS), this study aims to determine the relationship between the increase in land area and oil palm plantation production over the past 10 years. This study uses a quantitative method with a correlative approach. Data analysis was carried out using a bivariate correlation Pearson correlation test to determine the positive relationship between plantation area and oil palm production. The results of the analysis showed a significant positive relationship between the land area variable and oil palm production in both the Sumatra and Kalimantan regions, this is indicated by a positive number and a strong correlation of 0.852 for the Sumatra region and very strong, namely 0.996 for the Kalimantan region. In addition, the results of the interpretation of the correlation by looking at Sig. (2-tailed) also show that between the land area variable and production there is a significant correlation, namely 0.002 for the Sumatra region and a value of 0.000 for the Kalimantan region. Although the correlation between land area and production shows a positive value and has a very strong correlation, there are still other factors such as technology, climate, and management practices that also play a role in influencing palm oil production results.

Spatial zoning and effect evaluation of county high-standard farmland siting delineation for sustainable cultivated land use in China: A case study in Dali, Shaanxi

High-standard farmland construction is critical for sustainable land use and food security in China. Currently, scientific siting delineation for high-standard farmland at the county level is lacking. Delineation through evaluation and zoning is essential to improve land productivity. This study focuses on Dali County in Shaanxi Province, Fenwei Plain. It analyzes cultivated land changes using the land use transfer matrix and the PLUS. By integrating macro “township-parcel-grid” and micro “farmer” perspective, it establishes a comprehensive evaluation system for high-standard farmland delineation. We delineate construction zones and evaluate potential effect of high-standard farmland. The results reveal that: (1) From 2000 to 2020, the cultivated land area generally decreased. The permanent basic farmland positively contributes to the increase of cultivated land. Land use simulation in 2030 results show that the urgency for land consolidation. (2) The delineated high-standard farmland area in Dali is 85,081 hm2, with comprehensive evaluation index values ranging from 0.2229 to 0.5970, indicating that Dali has the potential for continuous construction of high-standard farmland. (3) This study zones high-standard farmland construction according to the difficulty and time sequence. Delineated high-standard farmland can play potential effect of agglomeration and demonstration, sustainable and coordinated development and grain production capacity increasing. We offer a scientific method for delineating zones of high-standard farmland within county, providing recommendations for sustainable high-standard farmland construction. It serves as a reference for the gradual conversion of all permanent basic farmland to high-standard farmland in China.

An online tool with Google Earth Engine and cellular automata for seamlessly simulating global urban expansion at high resolutions

Projecting global urban expansion is crucial for environmental assessment under climate change scenarios. However, existing global future urban land products are typically provided at coarse resolutions (1 km) due to data and computing limitations. This hinders the accurate assessment of the impacts of global urban development at finer scales. Thus, we develop the first Cellular Automata (CA) online tool for simulating future global urban expansion in Google Earth Engine (GEE-CA), which can simulate future urban land change at a 30 m resolution under different SSP scenarios. GEE-CA enables seamless simulations of future urban land at high resolution through a partitioned parallel strategy. Seven large urban agglomerations are simulated under shared socioeconomic pathways as representative regions to present our fine-scale results. Comparatively, our datasets preserve significantly more spatial details than existing global urban land products. The improvement in resolution from 1 km to 30 m reduces errors by a range from 7.11% to 21.27% in the estimation of future urban area. So far, the proposed GEE-CA tool allows users to generate urban land projection maps for any defined region with a resolution as high as 30 m.

A Review of Agrivoltaic Systems: Addressing Challenges and Enhancing Sustainability

Agrivoltaics is a relatively new term used originally for integrating photovoltaic (PV) systems into the agricultural landscape and expanded to applications such as animal farms, greenhouses, and recreational parks. The dual use of land offers multiple solutions for the renewable energy sector worldwide, provided it can be implemented without negatively impacting agricultural production. However, agrivoltaics represent a relatively new technology, facing challenges including economic viability, vulnerability to wind loads, and interference with growing crops. This paper reviews the recent research on integrating agrivoltaics with farming applications, focusing on challenges, wind impact on agrivoltaics, and economic solutions. The effect of agrivoltaics on temperature control of the lands is a critical factor in managing (1) water and the soil of the land, (2) animal comfort, and (3) greenhouse productivity, positively or negatively. In this review, a contradiction between the different versions of the American Society of Civil Engineers (ASCE) standards and the wind tunnel results is shown. Important factors affecting the wind load, such as damping and mass increase, optimum stow position, and aerodynamic edge modification, are highlighted with emphasis on the significant knowledge gap in the wind load mitigation methods.

Can Soil Spectroscopy be a Strong Alternative to the Conventional Methods of Analysis?

Soil is considered as the source of life on the globe. Although, numerous research studies, the soil is not completely understood whereas it is dynamic complex matrix include many simultaneous processes. The conventional methods of soil testing are the most reliable for assessing the land productivity and management. Unfortunately, these methods are time consuming and laborious as well as costly and hazardous to the environment. Therefore, the soil spectroscopy technique provides the functions of detecting, characterizing, quantifying and mapping several soil properties based on the uses of different kinds of the sensors (ground-based, airborne-based, and satellite-based). An integration of soil spectroscopic data, data processing, and modelling is considered as an effective tool for estimating soil parameters. Although these advanced techniques able to predict the majority of soil properties, there are some of these properties require more experiments for building accurate calibration models for estimation. Moreover, creating accurate soil spectral libraries (SSLs) for specific areas or soil types is very crucial for saving time, effort, expenses of soil surveying, sampling, and analysis. The application of these SSLs has a big limitation of the continuous variability of the soil properties over time. Thus, establishing extensive spectral libraries is important and mandatory for covering the small scaled areas’ variabilities as well as available soil types. Till now, the soil spectroscopy is not entirely replacing the conventional testing methods of soils because these techniques need future applications to be trusted and guaranteed of their effectiveness.

Effect of fertility levels and stress mitigating chemicals on nutrient content, uptake, intercropping advantage and competition effect in cowpea-baby corn intercropping

The primary goal of this study was to analyze how various row ratios of intercrops, in conjunction with different fertilizer levels with spray of two stress mitigating chemical, affect nutrient content, land productivity, and economic viability during Summer season. Furthermore, we aimed to explore the competitive dynamics within legume/cereal intercropping systems. Hence, A field experiment at Agriculture University, Kota, during the summers of 2019 and 2020, investigated different cowpea + baby corn intercropping system's intercropping indices, nutrient dynamics, uptake, and post-harvest soil nutrient balance under varying recommended fertilizer levels and foliar spray of stress mitigating chemicals. Using a split-split plot design replicated four times, the experiment involved thirty treatment combinations, including five intercropping techniques viz. Sole cowpea, sole baby corn, cowpea + baby corn 2:1, cowpea + baby corn 3:1, cowpea + baby corn 4:1 in the main plot, three fertility levels viz. 100 %, 125 % and 150 % recommended dose of fertilizer (RDF) in subplots, and two stress mitigation chemicals; CaCl2 0.5 % and KNO3 1% in sub-subplots. The findings revealed notable trends, including nitrogen (N) and (P) content in cowpea seeds and straw, baby corn cobs and fodder, as well as enhanced land-equivalent ratio (LER) and monetary advantage index (MAI) within the cowpea + baby corn 2:1 row ratio. However, despite these advantages, total N and P uptake were markedly higher in sole crops. Notably, sole cowpea demonstrated the highest actual N and P balance and lowest was under sole baby corn. Among the fertility levels, the 150 % RDF level exhibited the most favorable outcomes across various parameters, including LER, MAI, NP content, and uptake in both crops. Additionally, higher fertility levels correlated with increased apparent and actual soil nutrient balances. While, among stress mitigation chemicals, CaCl2 0.5 % resulted in significantly heightened N and P uptake. Hence, to optimize intercropping dynamics and maintain soil nutrient balance, it is advisable to intensify cowpea cultivation along with baby corn in a 2:1 row ratio, utilizing 150 % RDF is beneficial. Additionally, alleviating higher temperature stress during the summer season can be achieved by applying a 0.5 % solution CaCl2 through spraying at the flowering and pod development stages of cowpea.

Frontiers of fortune: mobilising land, water, and collective identity for watermelon production in Southeastern Morocco

ABSTRACT Watermelon production has rapidly increased in Morocco over the last 15 years. Since its independence in 1956, Morocco has promoted the production of early-season fruits and vegetables for European supermarkets to boost the national economy and improve rural livelihoods. Today, the expansion of watermelon production in arid regions of the country has had profound impacts on local land and water resources. In Zagora, a pre-Sahara oasis region in the southeast of the country, watermelons have contributed to the overuse of aquifers, trapping farmers in cycles of accumulating debt, and increasing conflict over land. Drawing on interviews and participant observation with residents and officials from 2021-2023, this paper demonstrates how a pastoral community embraced watermelon production in an effort to engage with the agro-export sector that drives the country's agricultural growth. Yet rather than contributing to the overall development of the region, watermelon production has deepened gender and economic disparities within the community and privileged a small group of farmers with access to capital. Although authorities restricted watermelon production in 2023, larger investors simply moved production, leaving small farmers to confront the volatile market while trying to sustain land, water, and collective identity in the region.

Production and management practices and technologies used for growing potatoes and tomatoes

Purpose. The aim of this study was to assess production and management practices and technologies used by farmers for tomato and potato production, as well as their productivity. Methodology / approach. This research was conducted in Ziway-Dugda and Tiyo districts of Arsi Zone in Oromia National Regional State of Ethiopia during 2022 cropping season. Data were collected from 400 households in 10 kebeles (local administrative unit) of both districts using Kobo toolbox from respondents through face-to-face interview and descriptive analysis using SPSS version 22. Results. The results of the study showed that farmers in the study areas used different pre-harvest practices. These include cultivation tools and methods, planting locations, tomato staking, potato hilling and irrigation practices to successfully grow vegetables and increase land productivity by rotating different crops on their land. Various diseases, weeds and insects have been observed on their farms, which were managed by cultural, agronomic, mechanical and chemical management practices on tomato and potato farms during the last cropping years in the study districts. Thus, majority farmers in the study areas have used insecticides and fungicides on tomato and potato farms; but most of the weeds were removed by hand weeding. Most tomato and potato farmers have determined the type of chemical and its use from their own previous experience, in consultation with salespeople and extension agents in their regions. However, the study results showed that there are unused production and management practices for tomato and potato cultivation by some farmers. There are many production and management practices and technologies used by farmers to improve vegetable productivity in the study areas, although some farmers did not adopt improved production and management technologies, resulting in reduced production, which requires future interventions to increase their capacity through training and technology adoption. Originality / scientific novelty. This study stands out in the field of production and management practices and technologies used by smallholder tomato and potato producers due to its innovative approach and unique contribution to existing knowledge and skills. While previous studies have examined the relationship between production and management practices and technologies in an agricultural context, particularly focusing on state farms, our study focuses on small-scale tomato and potato producers. Through our thorough case study research and interview structure, we not only deepened our understanding of production and management practices in the agricultural sector, but also provided practical recommendations for improving the efficiency and sustainability of small-scale tomato and potato producers on different farms/fields. Practical value / implications. The findings of this study can be used to develop recommendations for policy makers and researchers on how to improve labour productivity in the future Thus, the policy focuses on developing strategies for producers to adopt modern production and management practices and technologies, raising farmers’ awareness of available technologies, improving management practices and increasing crop productivity in the study area.

A stringent failure: Regulators do not use available tools to protect aquatic ecosystems from clearcut forestry impacts in New Zealand

Effective regulation of land-use activities in steepland areas is crucial to protect downstream ecologies and human life as intense rainfall disturbances become more frequent globally. In Aotearoa New Zealand extensive synchronous clear-cutting of Pinus radiata monocultures on steep convergent landforms, and associated earthworks, causes ongoing accelerated erosion, excessive sedimentation, and debris-laden landslides after adverse weather events. This study examines the implementation of national forestry regulations established in 2018, which also enable regional councils to create more stringent rules to protect aquatic ecosystems. All sixteen councils were surveyed in 2021 and 2022 for stringency in planning provisions; and four regions seriously affected by Cyclone Gabrielle in 2023 were resurveyed in 2024. The cyclone caused loss of human life and calamitous damage to housing, infrastructure, and productive land uses from floods exacerbated by clearcut logging debris. All councils had administratively adopted the national regulations into their existing freshwater and coastal resource management plans. Twelve councils retained existing rules that conflicted with the regulations, but these rules do not protect all regionally significant aquatic ecosystems nor minimise landslide risks. No council, except Gisborne, had instigated the expensive and lengthy statutory resource management plan change process, nor taken a ‘strategic and principled’ approach to develop more stringent regulations, such as tougher restrictions on clear-cutting, earthworks, and replanting on steep erosion-prone convergent landforms to protect aquatic ecosystems and vulnerable communities. The government did tighten the management of logging debris after the cyclone, but the national regulations remain ineffective in addressing clear-cut practices maladaptive to intense rainfall and continue to permit replanting on convergent landforms. The regulations need urgent amendment to require councils to develop and implement a strategic and principled approach to stringency to better protect aquatic ecosystems, human life, economic livelihoods, and public infrastructure. Water quality monitoring is also currently inadequate, as no council systematically monitors the effects of forestry activities on sedimentation rates, which inhibits the ability to compare across and between regions. Foresters are not required to monitor water quality, which also stymies assessments of compliance and policy effectiveness. Councils regularly monitor rivers, lakes, and estuaries, but rarely the effects of individual land uses. This means that sediment or other contaminants cannot be parsed to different land use activities, undermining attempts to set catchment limits. It can also take decades at current monitoring levels to defensibly show any water quality improvements after changes to land use regulations. The current environmental limits approach of setting individual water quality attribute targets is highly unlikely to drive changes to maladaptive and ecologically degrading land uses. A new environmental management approach is needed that prohibits or effectively constrains hazardous and adverse activities.

Impact of High-density Planting Spacing on Physiological Traits of Cocoa Grown under Coconut Trees

High-density planting (HDP) maximizes land productivity. Optimizing cocoa spacing under coconut trees enhances physiological traits and yield potential. Despite cocoa's integration into coconut agroforestry, spacing's impact on cocoa physiology is unclear. Studying this influence provides insights for better planting strategies, improved crop performance, and sustainable cocoa production in agroforestry settings. The experiment was conducted at the Coconut Farm of the Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. Employing a Randomized Block Design (RBD) with eight treatments replicated three times, the study aimed to explore how different spacing levels influence physiological traits in cocoa cultivation. The treatments involved in the experiment included a double row of cocoa planted between two rows of coconut trees, with spacing configurations as follows: T1 (3m x 1.2m), T2 (3m x 2m), T3 (3m x 2.5m), and T4 (3m x 3m). Additionally, a single row of cocoa between two coconut rows was examined, with spacings represented by T5 (1.5m), T6 (2m), T7 (2.5m), and T8 (3m). Results indicated distinct patterns among spacing treatments, with significant differences observed in various physiological characteristics. Notably, T1 (3m x 1.2m) demonstrated the highest leaf area (462.71cm2) and leaf area index (4.85), while T8 (3m) exhibited the highest light interception (74.12%). Additionally, T3 (3m x 2.5m) showcased the highest chlorophyll index (40.52) in cocoa leaves. These findings underscore the importance of spacing configurations in influencing key physiological parameters in cocoa cultivation, providing valuable insights for optimizing planting practices.

Performance evaluation of Uruguayan dairy farming systems

In the last 20 years, the Uruguayan dairy sector has intensified and concentrated on higher cow productivity, maintaining the herd, smaller land, and fewer farms. The research aims are to identify, describe, and evaluate the economic performance of different types of dairy farms. A sample of 284 farms from the National Dairy Farm Survey 2019 was used (representing 2,021 dairies); using k-means Cluster analysis with the variables: cow productivity, stocking rate, land productivity, concentrate, roughage, and grass intake (per hectare). We identified six farm types, three with high participation of grass in the cows’ diets (HG, 60% or more of dry matter intake), and the other three focused on supplementation (HS); with three intensification levels (1-low, 2-intermediate and 3-high productivity per ha). For the 2018/19 season three types of farms presented the best economic performance (HS-3, HG-3, and HG-2), including those with the highest stocking rate and grass intake per hectare, and more than USD 225 Economic Farm Surplus (EFS) per hectare with the lower unitary cost. Other two types exhibited intermediate economic performance (HS-2 and HG-1) with EFS close to zero and unitary cost similar to price. And one type (HS-1) displayed the worst economic performance, with negative indicators and the largest number of farms with very low productivity.

Intensifying droughts render more Sahel drylands unsuitable for cultivation

Two-fifth of the world's population will be confronted by dire land and water shortage for food production by 2050. Here we provide nuanced insights into the Sahel dryland dynamics and rationale behind its underperforming croplands amid climate extremes. We develop a gridded multi-criteria drought index for the growing season (June-October) and analyse its spatial and temporal degree of uniformity to designate the drought, climate and cultivable zones. Evidence is drawn from Sahelian Sudan, representing 1.03 million km2 of the African Sahel, during 1940–2020. Results show that cultivation of marginal lands has persisted apace. The peak areas of these marginal lands explain ∼50 % of the variations in crop yield, considering the two staple crops, sorghum and millet. Furthermore, the low yields mismatch the steadily growing planted areas of these crops. Compared to wet conditions, droughts expand (shrink) the median size of hyper-arid (arid) area by 466 % (46 %), limiting farming opportunities for 3.5–35.8 % of the croplands. The northernmost borderline of the arid zone determines the rainfed suitability, but potentially cultivable arid areas require contingency risk-reduction plans. Conversely, semi-arid and dry sub-humid zones reveal areas endowed with uniform climate. Skillful climate forecasting should thus guide policymaking towards sustainable agriculture therein. The paper suggests paths towards more effective agricultural policy interventions. Agricultural production entails the Sahel drought being defined in terms of agricultural impacts instead of meteorological conditions. Land use planners and inhabitants must relieve the plight of misconceiving and overlooking the fact of intrinsic interannual rainfall variability. Determining what a dangerous drought is for the Sahel agriculture sector or system is crucial. Sahel farming systems should opt for highly flexible agricultural practices based on the above-identified cultivable areas.

Spatiotemporal dynamics of land use land cover change and its drivers in the western part of Lake Abaya, Ethiopia.

Understanding the dynamics of land use/land cover (LU/LC) changes and what drives these changes is essential for creating effective strategies for sustainable land management. It also helps to monitor the impact on ecosystems and biodiversity, which is crucial for policy-making. This study focused on assessing the trends, rates, and extent of LU/LC change and its causes in the western part of Lake Abaya in Ethiopia. To achieve this, we used a supervised classification method with a maximum-likelihood algorithm to map different land use land cover types. Additionally, we gathered information through field observations, focus group discussions (FGDs), and key informant interviews (KIIs) to identify the factors driving LU/LC change and its consequences between 1990 and 2022. The study findings revealed that vegetation and wetlands significantly decreased over this period, while water bodies, agricultural land, and settlements expanded at the expense of other land uses. The average normalized difference vegetation index (NDVI) values decreased from 0.368 in 1990 to 0.135 in 2022, indicating declining vegetation health. Local communities point to several factors responsible for these changes, including the expansion of agricultural land, increased settlement, firewood collection, and charcoal production (as proximate/immediate drivers), as well as population growth, poverty, unemployment, climate change, and policy-related issues (as underlying causes). Thus, it needs the development and implementation of an integrated and sustainable land management system, and strong land use and restoration policies in order to halt or reduce the rapid expansion of agricultural land and settlement areas at the expense of vegetation and wetlands.

Enhancing Farm Household Income Through Efficient Arabica Coffee Cultivation In Simalungun, North Sumatera

North Sumatera is the largest producer of arabica coffee in Indonesia with 29%. However, coffee farmers are always faced with various field problems such as high fertilizer prices, declining production and various traditional cultivation practices that cause low productivity levels. So that in maintaining overall cropping it is necessary to know the efficiency of farm management with efficient coffee management it can increase farmer income, improve the quality of life of farmers, absorb labor, reduce costs and create a sustainable system. The method used in this research is to use the Data Envelopment Analysis (DEA) model to determine the efficient value and the Ordinary Least Squares (OLS) model to determine the efficient influence. The results of this research with the DEA model show that from a total of 133 respondents, the inefficient value is 51%, low efficient 25%, medium efficient 13%, and low efficient 11%. While the OLS model shows that the total cost and total income of farmers can significantly affect the efficiency value, the total production of farmers has no influence on the efficiency value. The research findings imply that improving efficiency requires modernizing technology to overcome traditional management such as the use of superior seeds and fertilizer inputs to increase land production. It also requires the support of relevant policies and institutions that are able to guarantee the availability of production facilities such as superior seeds and fertilizers that are easily available to farmers at affordable prices.

Agroecological Assessment of Arable Lands in the Leningrad Region of Russia under the Influence of Climate Change

The paper presents an analysis of the influence of climatic characteristics on the rating of land suitability for agricultural use. Soil fertility is one of the most important factors in land productivity and crop capacity; it is a complex value that depends not only on agrophysical and agrochemical soil properties but also on other natural factors, such as climate. There are different methodical approaches for a quantitative assessment of fertility level. The objectives of the research were to understand whether the distributions of active temperature sums and annual precipitation sums have a significant effect on the spatial and temporal heterogeneity of the rating assessment of land suitability for agricultural use in the example of the Leningrad region. The estimation and comparison between Semenov–Blagovidov’s method of quality land estimation and Karmanov’s method of appraisal of soils are given in this article. Karmanov’s method is highlighted in this paper for its ability to assess soil’s ecological indices more effectively than traditional methods. The research suggested that climate change may lead to increased variability in soil quality, with potential benefits for agriculture under certain climate scenarios, but at the same time, excessive temperatures in summer and precipitations might become a limiting factor, pushing down yields. The results of such assessment show that the performed calculation models can be used to forecast crop yields for future periods.

Seeking a multi‐dimensional approach to understand agricultural commodity expansion in Asian tropics

AbstractAgricultural commodity expansion into natural and semi‐natural ecosystems in Asia is a multi‐dimensional sustainability challenge posing a threat to natural and human capital. At the symposium pertaining to agricultural commodity landscapes organized at the 59th meeting of the Association for Tropical Biology and Conservation, we aimed to identify key aspects that require further attention to address the negative impacts of commodity‐driven agricultural expansion in the Asian tropics. Using a combination of insights obtained both from participants' research and those that developed organically in the symposium, we identified five key themes: (1) Robust land use suitability assessments to determine the viability of agricultural expansion or other competing demands on productive land in given landscapes; (2) the need for plot‐level studies of soil biodiversity and ecological functions for commodity crops; (3) Irrigation for commodity crops with blue and green water and evaluating co‐dependent drivers and outcomes; (4) an improved understanding of local producer motivations and supply chains and (5) the analysis of co‐benefits, trade‐offs and synergies in agro‐commodity systems. These themes include the various steps involved in agricultural commodity expansion, right from land selection and crop patterns to aspects pertaining to the post‐harvest value chain. These themes are inter‐connected and span across multiple local and regional spatial scales in tropical Asia but hold relevance to agricultural landscapes elsewhere too. Immediate and sustained attention on these themes would secure multiple goals of sustainable land use, biodiversity conservation, climate change mitigation and human well‐being.

Towards a more realistic estimation of urban land take by combining cadastral parcels and building footprints

Despite its importance as a research issue, a widely accepted methodology of estimating land take resulting from urbanization has not yet been reached. Accurate geospatial datasets are currently available at a European and global level; however, different methods of quantifying urban land take could lead to diverse outputs, potentially resulting in underestimation. This can be alarming as encroaching urban sprawl is emerging as a major environmental challenge by destroying natural habitats, consuming productive agricultural land, and contributing to climate change by increasing energy demands. To address this knowledge gap, we propose an estimation of urban land take that combines cadastral parcels and building footprints. Land parcels can be considered as a suitable minimum mapping unit as they are directly related to the spatial level where economic decisions on land use conversion are made. The proposed geospatial method is compared to methods that depend on datasets of High Resolution Layer Imperviousness, Global Building Footprints (alone), Corine Land Cover, Urban Atlas, and Global Human Settlement Layer. The method is exemplified in case studies in Greece, specifically: (a) two islands of the South Aegean Region (Mykonos and Thera), that are heavily impacted by tourism development and sprawl and (b) a peri-urban zone (Thermaikos-Michaniona) within the metropolitan area of Thessaloniki, impacted by intense suburbanization. Results show that urban land consumes important shares of available land since the mid-20th century, this fact highlighting the dynamic encroachment of urban development. Calculation shows that other methods could underestimate urbanized areas by up to 80%–90%. In the discussion section, the advantages of shifting the focus from the pixel to the parcel are further justified, while explicit links to spatial planning policies for sprawl containment are drawn. Such policies could be informed by more realistic estimations of urban land take, in order to proceed with strategic and regulatory measures to support the ‘no net land take’ policy of Europe.

Green Initiatives for Climate Change Mitigation in Palakkad District of Kerala, India

Trees and forested ecosystems play a significant role in in meeting global commitments on sustainable development as well as adaptation to climate change and mitigation of its impacts. Aggressive tree planting goals to achieve canopy cover growth targets are a common manifestation to overcome the climate change challenges. Miyawaki forest creation, a method developed by Japanese botanist Akira Miyawaki, involves planting trees per square meter which is intended for intensification of green cover to support local biodiversity. A food forest is essentially a planned and planted forest of food plants that provides a variety of food throughout the year. While both Miyawaki forest and food forest aim to restore ecosystems and enhance biodiversity, they differ in their design, purpose, and management practices. Hence a study on comparative analysis of food forests and Miyawaki forests was envisaged to highlight their respective benefits, challenges, and implementation strategies. The present investigation was undertaken on selected institutions of Palakkad district of Kerala namely Krishi Vigyan Kendra Palakkad where Miyawaki forest patch is created at its premises and V T Bhattathiripad College, Sreekrishnapuram where food forest is established. From this study it is understood that Miyawaki forest is reconnecting with the nature by harboring an array of native flora and fauna promoting biodiversity conservation and habitat restoration while food forest is reconnecting with nature by providing food source for pollinated server, as a habitat for many animals and it is very ecofriendly because don’t require any chemical pesticides. These techniques are highly effective in the establishment of urban forests as well as converting unproductive waste lands into ecological and socially beneficial productive lands.

Moderating Effect of Strategic Linkages on Corporate Leadership and Organizational Performance in Kenya Agricultural and Livestock Research Organization (KALRO)

The urgency of securing safe, affordable, reliable, and nutritious food amid a growing global population and shrinking land productivity underscores the pivotal role of corporate leadership in fostering strategic partnerships and organizational performance. This is crucial for organizations like Kenya Agricultural and Livestock Research Organization (KALRO) to enhance performance and drive agricultural innovation that ensure achievement of national targets and mandate. Understanding the dynamics between leadership effectiveness, strategic alliances, and organizational performance is essential for addressing food security challenges and optimizing the impact of agricultural research institutions worldwide. The projected 27% increase in global population by 2050 emphasizes the need for strong corporate leadership and strategic partnerships to ensure balanced diets for over half a billion smallholder farmers. Despite Kenya's higher productivity than East Africa and Africa averages, challenges remain in enhancing food security through effective leadership and strategic alliances, particularly within institutions like KALRO. The study explored the moderating influence of strategic linkages on the relationship between corporate leadership and the performance of KALRO. Rooted in organizational excellence, upper echelons, legitimacy, and stakeholder theories, the research employed a pragmatic philosophy, and mixed methods design to mitigate bias. The target population included 75 management organs, with 60 directors and 188 top leadership units as units of observation. Quantitative analysis, using a composite regression model and ANOVA, revealed a significant impact of strategic linkages on corporate leadership and KALRO's performance. The study verified consistent variances and normality across variables, supporting parametric analyses. Autocorrelation analysis indicated no significant autocorrelation. Multicollinearity tests showed acceptable values, ensuring the reliability of the regression model. No outliers were detected. Cronbach's alpha scores demonstrated strong internal reliability. Significant correlations confirmed associations between variables, aligning with previous research findings. Strategic linkages emerged as enhanced moderator, explaining 69.4% of the variance. In this case, the moderator variable amplified or strengthened the relationship between corporate leadership and organizational performance of KALRO. Rejecting the null hypothesis highlighted the positive impact of strategic linkages on performance. Conditional effects analysis revealed strong corporate leadership influence at low strategic linkages but diminishing at higher levels. Recommendations encompassed gender diversity, inclusive leadership development, regular performance appraisals, enhanced monitoring and evaluation system, and improved linkages. The findings provide valuable guidance for KALRO's leadership amid competing priorities and budgetary constraints.

Colonial transformation of the Aembu land access and labour division systems in food crop production from 1906-1963

This study examined the colonial transformation of the Aembu access to land and labour division in food crop production from 1906-1963. Colonial practices and policies undermined the Aembu land and labour systems in food crop production. Methodologically, the study used descriptive research design and Articulation of Modes of Production Theory. The study was conducted in Embu East, Embu West and Embu North sub-counties of Embu. The study targeted a population of 16,144 people based on the 2019 census. Corroborated data was obtained from oral, archival and secondary sources to establish the reliability and validity of the research. The study’s findings were that the creation of African reserves to pave way for white settlement and labour supply from Africans led to the abandonment of crop farms since they were far away; the reserves had limited land sizes with poor soils for the production of enough food while most of the food storage facilities were destroyed in the process of migration and that during the political crisis of World Wars and Mau Mau, labour in food crop production was reduced. It concluded that colonialism transformed the Aembu land and labour systems while the co-existence of pre-colonial and colonial access to land and labour systems on the production of food crops exposed the community to famines. The study recommends that policymakers should come up with strategies for promoting traditional forms of access to land and labour to ensure adequate food crop production.
