PEMETAAN POTENSI SUMBER DAYA AIR UNTUK PERTANIAN LAHAN PRODUKTIF (STUDI KASUS: DESA KAMBUHAPANG DAN DESA KAMBATAWUNDUT)

Desa Kambuhapang and Desa Kambatawundut are villages located in the Lewa District of East Sumba Regency. This area is characterized by arid conditions and experiences an 8-month-long dry season. Most of the population in this region is engaged in agriculture, particularly dryland farming. The main water supply for agriculture in this area comes from low rainfall, resulting in limited water availability. The purpose of this study is to assess the water discharge potential in these two villages. Secondary data, including rainfall data, was obtained from two stations: the Waingapu meteorological station and the Lewa Paku rain station. Additionally, climatological data from 2012 to 2021 was used. ArcGIS 10.7 software was employed to map the area using Digital Elevation Model (DEM) data. The Modified Penman method was used to determine evapotranspiration, while the F.J. Mock method was applied to calculate the reliable discharge. The results showed that the average annual water availability, according to the F.J. Mock method, is 16.45 m³/s for the Lay Mbeda River and 16.54 m³/s for the Wai Wei River. The villages of Kambuhapang and Kambatawundut have sufficient water availability, with a total of 74.18% across an area of 63.12 km². The adequate water availability in these two villages is evident from the minimum discharge during the dry season, ranging from 6.60 to 7.12 m³/s. This indicates that the villages have sufficient water resources to support the expansion of productive agricultural land for the local community. The utilization of these water resources could be further optimized by providing supporting infrastructure to increase runoff storage, such as water reservoirs, small ponds, or retention basins.Keywords: mapping, water potential, water availability, waingapu, lewa paku

The Influence of AB Mix Concentration and Types of Wicks on Brix Value in Cherry Tomatoes (Solanum lycopersicum var. cerasiforme) by Hydroponic Wick System

Hydroponic technologies offer an alternative way to cultivate cherry tomatoes in times when a downfall is seen in productive agricultural land. This research aims to know the correlation between the Brix value of cherry tomatoes and AB mix concentration by a hydroponic wick system. The research method used was an experimental method using a factorial Randomised Block Design. The treatments consisted of K1 = 1900 ppm, K2 = 2700 ppm, K3 = 3500 ppm, S1 = felt, S2 = wool yarn, S3 = stove wick, S4 = cotton rope. Each treatment was repeated thrice. The result showed that the concentration of AB mix solution at 3500 ppm (K3) gave a better result than other concentrations, with an average percentage of Brix valued at 8.71%. At the same time, using felt (S1) as a wick showed the best result with the average percentage of Brix valued at 8.02%. The correlation analysis of AB mix concentration and Brix value resulted in a coefficient of 0.61 which showed a strong correlation between the two variables. This indicates that different levels of concentration of AB mix solution can influence the Brix value of cherry tomatoes. Keywords: hydroponic cherry tomatoes, ab mix concentration, wick system correlation

THE CURRENT STATE OF AGRICULTURAL LAND USE IN THE CONTEXT OF SUSTAINABLE DEVELOPMENT

This article discusses the rational use of agricultural land, taking into account structural and resource indicators for sustainable development. The effectiveness of land use in farms with different forms of land ownership depends on increasing labor productivity, strengthening the economy regime, increasing the intensification of production, using internal reserves and opportunities for agricultural production and, especially, rational use of land. The basis for the formation of sustainable land use should be strict observance of the established relationships between disturbed and undisturbed territories. Undisturbed territories should be considered as a stabilizing factor neutralizing anthropogenic impacts on the landscape. In this regard, the tasks of preserving productive agricultural land, optimizing arable land and acreage in terms of quantitative and qualitative characteristics of land are becoming a priority. The solution of these tasks is connected with the improvement of technologies for maintaining and increasing the bioproductivity of agricultural lands, the development of technologies for rational land management, land use and land protection, the creation of effective organizational and legal mechanisms for managing agricultural lands, as well as the development of state monitoring of agricultural lands. In order to approach the practice of determining the efficiency of land use, it is necessary to focus in more detail on its factors according to the selected functional subsystems and types of efficiency.

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.

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.

Biochar Production from Plant Residues: A Sustainable Approach for Carbon Sequestration and Soil Fertility Improvement

This review article explores the sustainable practice of producing biochar from plant residues, effectively transforming green waste into a valuable resource commonly referred to as “green gold”. It discussed mainly on the pyrolysis process of biochar production, and the impact of different pyrolysis methods on the resulting biochar's properties, including surface area, porosity, and nutrient holding capacity. Further, the review analyzes the multifaceted benefits of biochar for soil health and plant growth. It highlights how biochar can improve soil structure, increase water retention, and enhance nutrient availability, leading to healthier and more productive agricultural lands. Additionally, the review explores biochar's potential in influencing the soil microbial community, potentially promoting beneficial organisms and suppressing harmful pathogens. It also explores biochar's role in mitigating climate change by capturing and storing atmospheric carbon, effectively reducing greenhouse gas emissions. However, a balanced perspective is maintained by acknowledging potential drawbacks associated with biochar use, such as the need for further research to optimize production methods and potential negative impacts on certain soil fauna. This review highlights biochar's promise as a sustainable, cost-effective solution for agriculture and environmental issues. Biochar adoption can lead to a greener future through carbon capture, soil health, and waste management.

Optimal Exploitation Strategies of Sustainable Utilization of Egypt's Fossil Groundwater Reserves

Groundwater-dependent areas in Egypt are being reclaimed as a result of the impending food crisis. Thus, the national project for land reclamation aims to turn vast tracts of desert land into productive agricultural land. Even while this kind of rural development is desperately needed, relying solely on fossil groundwater sources is a dangerous course of action. Therefore, it is crucial to use these groundwater resources quite carefully. Selecting a safe pumping schedule to prevent aquifer depletion and/or seawater intrusion is just one of the goals. However, using groundwater simulation models based on optimal approaches would introduce exploitation plans that, at the same time, guarantee the aquifers' sufficiency for continued development and maximize the agricultural investment. Thus, a groundwater flow model was generated using the FEFLOW software to explore the Moghra aquifer’s potential for extensive rural development. The maximum pumping regime that coincides with the regulation rule that was set by the MWRI for the next 100 years has been concluded. There is a potential for sustainable exploitation of this water resource to irrigate a total area of 85,715 acres (34,687 ha). The resulting drawdown is expected to reach 95.4 m. Furthermore, a few mitigating techniques are suggested as efficient ways to stop or impede the saltwater intrusion, such as the installation of subterranean barriers and brackish water scavenger wells. Without a doubt, the intended findings would serve as the foundation for wise local water management choices that might strike a balance between the socioeconomic welfare of our nation and environmental preservation. The outcomes of the project can be used by decision making and stakeholder to achieve sustainable water resources management in the new lands for reclamation projects in the northwestern of Nile Delta, Egypt.

The impact of land-use change on the ecological environment quality from the perspective of production-living-ecological space: A case study of the northern slope of Tianshan Mountains

Elucidating the relationships between production-living-ecological space (PLES) and ecological environments can help identify new strategies to promote sustainable development. The northern slope of the Tianshan Mountains represents a typical complex ecosystem characterized by mountain-oasis-desert interactions in arid regions with prominent human-land conflicts and intricate ecological environments. Here, we analyzed the spatiotemporal variations in land use in the study area from the perspective of PLES. Based on moderate resolution imaging spectroradiometer (MODIS) data, an improved remote sensing ecological index (IRSEI) suitable for arid areas was established to evaluate the eco-environment quality (EEQ) by introducing salinity and cleanliness indexes. A stepwise regression model was then used to identify and quantify the impact of the PLES transfer modes on EEQ. The results showed that: (1) The oasis area was dominated by agricultural production land, whereas the desert and alpine areas were dominated by other and pasture ecological lands, respectively. The oasis area primarily involved the conversion of pasture ecological land to agricultural production land, whereas the desert and alpine areas showed mutual transformation of ecological space. (2) The size relationship of the EEQ in each sub-region was alpine region (0.555) > oasis region (0.509) > desert region (0.424). The EEQ in the study area showed an overall upward trend but decreased in the alpine region. (3) Changes in the PLES and IRSEI primarily occurred in the oasis region. Among the 21 PLES transfer modes that affect EEQ, an increase in agricultural production land was the primary mode that enhanced IRSEI, whereas an increase in impervious surfaces significantly decreased IRSEI. The degree of influence was as follows: industrial and mining production (−0.594) > urban living (−0.462) > rural living land (−0.316). In addition, EEQ is also affected by the combined effects of climate, topography, and other factors. By proposing IRSEI, we highlight the impact of land-use transfer mode on ecological environment quality from the perspective of PLES, which can provide a reference for ecological environment evaluation in arid areas and is of great significance for land-use planning and ecological environment protection.

Nutrient cycling on dairy farms in the Netherlands: The role of farm structure, management and trade-offs

Food production is a major driver for crossing planetary boundaries. Improving nutrient cycling may enable maintaining production while reducing environmental losses. This study assesses the current state of Dutch dairy on-farm nutrient (nitrogen- N, phosphorus - P) cycling through re-use of manure, scope for improvement and potential trade-offs. Data of 27 farms between 2006–2022 were used.Nutrient use efficiency (Output/Input) varied widely, with an average of 0.39 (0.29–0.47) for N and 0.88 (0.69–1.01) for P. Combining circularity and efficiency indicators showed that most gain in efficiency could be made by increasing cycled flow. Management related with improved cycling had lower external nutrient inputs, both from fertiliser and feed. Farm structure mattered for farm performance, as extensive farms with lower external N inputs from fertiliser or feed had higher N cycling and lower greenhouse gas emissions, but at the costs of agricultural land use and productivity.

Assessing Land Suitability for Lamtoro (Leucaena leucocephala) in Reclaimed Mining Lands of Sanggau Regency, West Kalimantan

This study evaluates the suitability of reclaimed zircon mining land in Sanggau Regency, West Kalimantan for cultivating Lamtoro (Leucaena leucocephala), a versatile plant used for forage and as a biomass energy source. Utilizing the weight factor matching method, we analyzed a range of land characteristics including soil texture, drainage, pH, and organic carbon content, as well as environmental factors such as temperature and rainfall. Initial assessments categorized the land as marginally suitable due to suboptimal drainage and soil texture. However, our research suggests that through strategic interventions—specifically improving soil texture using topsoil and enhancing drainage systems—the suitability of the land can be significantly upgraded. Detailed analysis shows that with these modifications, the land shifts from a marginal to a highly suitable rating for Lamtoro cultivation. The successful adaptation of Lamtoro in these reclaimed areas not only supports agricultural viability but also aids in the ecological restoration of post-mining landscapes, contributing to the achievement of sustainable development goals. This study underscores the potential of targeted land management strategies in transforming degraded mining areas into productive agricultural lands, providing a blueprint for similar reclamation efforts globally.

The article presents the results of assessment of agrobiological resources of landscapes of agricultural use of Turkestan region under conditions of changing climate, which were based on the developed concept of reference yields of H. Tooming. To develop an algorithm for assessing the agrobiological resources of the region, a climatic research base for 1941...2020 was created for 18 meteorological stations located in different natural zones, which made it possible to determine the peculiarities of the formation of different categories of agricultural yields due to climate change. The obtained results of the research on the state of agrobiological resources of landscapes of the region on potential productivity of agricultural lands, on photosynthetically active radiation (PAR) input using the concept of reference yields in spatial and temporal scales have shown that there is a stable trend to increase the potential productivity of agricultural lands on photosynthetically active radiation input, climatic potential-possible productivity and decrease the potential productivity of agricultural lands on - photosynthetically active radiation input, climatic potential-possible productivity and decrease the potential productivity of agricultural lands on - photosynthetically active radiation input.

Investigating the impact of urban growth on land use using spatial autocorrelation methods in Konya/Türkiye.

Land use land cover (LULC) change, global environmental change, and sustainable change are frequently discussed topics in research at the moment. It is important to determine the historical LULC change process for effective environmental planning and the most appropriate use of land resources. This study analysed the spatial autocorrelation of the land use structure in Konya between 1990 and 2018. For this, Global and Local Moran's I indices based on land use data from 122 neighbourhoods and hot spot analysis (Getis-Ord Gi*) methods were applied to measure the spatial correlation of changes and to determine statistically significant hot and cold spatial clusters. According to the research results, the growth of urban areas has largely destroyed the most productive agricultural lands in the region. This change showed high spatial clustering both on an area and a proportional basis in the northern and southern parts of the city. On the other hand, the growth in the industrial area suppressed the pasture areas the most in the north-eastern region of the city, and this region showed high spatial clustering on both spatial and proportional scales.

Analisis Sistem Jaringan Tata Air Pada Lahan Rawa Pasang Surut, Desa Telang Karya, P87S, Banyuasin, Sumatera Selatan

The world's growing population is increasing the need for land, prompting the conversion of productive agricultural land into non-agricultural purposes. This has led to a shift in agricultural development to sub-optimal lands, such as tidal swamplands. However, several problems arise along the way, including water management. A good water management network is necessary for supporting efficient water use. This study aims to analyze the water system network on tidal swamps to support agricultural activities. The survey and field observation methods were used to collect data. The results showed that the water system in Telang Karya Village, P87S, Banyuasin, South Sumatra, experienced sedimentation in the tertiary channel. In channel 3, the thickness of sediment reached 72 cm, resulting in silting, which reduces water discharge. Field observations revealed that sedimentation occurs due to the channels being overgrown by wild plants. This hampers the water flow, causing it to slow down or even stop. In some tertiary channels, the watergate operation needs to be carried out optimally. Maintaining the ideal conditions of tertiary channels is crucial, and watergate operations should be performed based on the needs of the plants.

Effect of Aqueous Extract of Ageratum Houstonianum on Seed Germination and Seedling Growth of Triticum Aestivum (Wheat)

Invasive plants are species that do not belong in a particular habitat but enter and establish themselves there. They are known for their adaptability and competitiveness in different environmental conditions. They tend to compete with crops for crucial resources, including water, light, and nutrients and can hinder crop growth and development through allelopathy. The aim of the current research was to investigate the allelopathic effect of aqueous extracts of Ageratum houstonianum on the germination and growth of wheat (Triticum aestivum) seedlings. The aqueous extracts were obtained from the leaves of A. houstonianum at various concentrations, including control, 25%, 50%, and 100%, and applied to pot and petri-plates cultures. The experiment was set up with 5 replicates for both the Petri plates and pot cultures. The study results showed that A. houstonianum aqueous leaf extracts had a significant impact on the germination and growth of T.aestivum. The concentrated (100%) aqueous leaf extracts of A. houstonianum significantly hindered the germination of seeds and growth parameters of T. aestivum. Additionally, the extract treatments of the weed species resulted in changes in soil pH and soil fertility. When invasive weed species grow alongside crops in fields, they may consume a significant number of resources required for crop growth, leading to a decrease in both the quantity and quality of agricultural output. Hence, this study highlights the potential adverse effects of invasive weeds on crop growth and development, and how they can negatively impact agricultural productivity. Therefore, there is a need for effective management strategies to control the spread of invasive weed species and preserve the productivity of agricultural land.

ANALISIS DAYA DUKUNG LAHAN PERTANIAN SEBAGAI UPAYA MENDUKUNG KETERSEDIAAN PANGAN DI KAWASAN SLEMAN TENGAH

The Central Sleman area is a peri-urban area directly adjacent to Yogyakarta, making land conversion increasingly prevalent and unavoidable. In comparison, the Central Sleman area has a role as one of the food barns due to fertile land conditions and is suitable for agriculture. Intensive conversion of agricultural land to non-agricultural land will result in the loss of productive agricultural land, resulting in decreased rice production. This will result in high rice imports and reduced employment in the agricultural sector. This research aims to analyze the development of agricultural land use, its projection, and the carrying capacity of agricultural land in the Central Sleman Region. The calculation of the agricultural land carrying capacity is based on Odum, Howard, and Issard. The results showed that the Central Sleman Area has a decreasing rate of change in the agricultural land area every year in Kapanewon. The calculation results of agricultural land's carrying capacity show that in 2020, land's carrying capacity exceeded 0.83. The results of the projection calculation in 2024 found that 4 out of 5 Kapanewon in the Central Sleman Region cannot achieve food self-sufficiency. Therefore, efforts are needed to increase the carrying capacity of agricultural land, mainly through increasing the productivity of food crops and protecting agricultural land from land conversion.

THE RIGHTS TO LAND, FOOD AND TOURISM RELATED TO AGRICULTURAL LAND CONVERSION IN BALI: HOW SUBAK PLAY A ROLE?

Bali, one of the world’s tourism destinations, is now facing a paradoxical situation because the increasing number of tourists visiting Bali is going hand in hand with the gradual reduction in productive agricultural land due to land conversion. This paper analyzes the massive practice of converting productive farmland for tourism in Bali. It offers a human rights law lens, particularly the rights to land, food, and tourism, to view the problem discussed in the paper. Legal research primarily reads international legal instruments, Indonesia’s laws and regulations, and some secondary materials. The paper suggested that although the Bali provincial government has issued rules and policies to prevent the practice of land conversion, the government cannot fully control it because many agricultural lands have ownership status. Therefore, there is an urgent need to increase awareness of local communities as landowners to prevent such a practice. This paper also proposes using subak, a traditional farming system, as the basis for ecotourism and agrotourism activities to tackle the problem of land conversion in Bali.

In this article, the impact of urbanization on the lives of the people of Serang City is discussed. This article identifies various impacts due to urbanization through research and analysis carried out. Urbanization in Serang City affects many aspects of community life and the environment. One of the main effects of urbanization in Serang City is changes in land use. Green spaces and agricultural land have been converted into housing, shopping centers, offices and other urban infrastructure. Thus, productive agricultural land is reduced, biodiversity is lost, and environmental damage occurs. With economic growth and development of urban infrastructure, public services, and access to education, urbanization increases employment opportunities for local residents. However, urbanization also brings social and lifestyle changes, which can influence cultural values, daily habits, and social interaction patterns. With demand for housing increasing and a shortage of affordable housing. Apart from that, changes that occur in urban infrastructure and the impact they have on infrastructure access and traffic must also be considered. The method in this research uses qualitative interview techniques. By gaining a better understanding of these impacts, it is hoped that sustainable solutions can be developed to exploit the positive potential of urbanization and overcome the problems faced by the people of Serang City.
