Automating the conceptual design of residental areas using visual and generative programming

The design processes based on parametric design and generative design allows multiple alternatives to be generated, analysed and corrected. The aim of the developed program was to automate the urban design concept development process for selected land units with a local development plan. This document, ordinances and other sources were the guidelines for the program to be developed. The solution-generating program starts by taking in the data, and then geometrical objects are created that have the right relationships to each other. Finally, results are evaluated on the basis of calculated indices and further generations are created taking into account the best options. This process must be overseen by a human, but with the development of machine learning and artificial intelligence, automation will progress, reducing human effort. The results of the study were collated and compared with other experiments in an in-depth literature review.

Review on Multilayer Farming: A Way Towards Farmer Prosperity

Multilayer farming is an innovative agricultural strategy that redefines traditional farming practices by harnessing vertical space to cultivate multiple layers of crops within a single agricultural system. This approach is designed to overcome challenges associated with land scarcity and inefficient land use. The concept involves arranging different crops in layers, utilizing the vertical dimension to its fullest extent. The layers can include ground-level crops, vines climbing on trellises, and even trees or shrubs, creating a multi-tiered ecosystem. This arrangement optimizes sunlight exposure, nutrient distribution, and water usage, resulting in enhanced productivity. One of the key advantages of multilayer farming is its potential to significantly increase overall yield per unit of land. By strategically combining plants that complement each other in terms of growth patterns, resource requirements, and ecological interactions, farmers can create a symbiotic environment that maximizes the use of available resources. Resource efficiency is a focal point in multilayer farming. The intercropping of different plant species helps in nutrient cycling, reducing the need for external inputs. Furthermore, the diverse plant composition can deter pests and diseases, reducing the reliance on chemical interventions. The vertical stacking of crops also allows for efficient water usage through integrated irrigation systems. Beyond its practical benefits, multilayer farming contributes to biodiversity preservation. The coexistence of various plant species fosters a more resilient and ecologically diverse agricultural landscape. This can have positive effects on soil health, pollination, and overall ecosystem stability.

Vyhodnocení růstu proveniencí borovice lesní v Čechách

This study examines the variability of Scots pine provenances in four Czech research plots from the same series of experiments conducted in 1972. 121 provenances from the Czech Republic and Slovakia were evaluated in terms of growth and morphological characteristics. The quantitative traits measured for each tree were its tree height and DBH. The stem volume was also calculated according to the volume equation (Petráš, Pajtík 1991). Among the qualitative traits, stem form, health status, branch thickness in the crown, stem damage, stem twist, stem clearing, stem cross-section, and taper were evaluated. The large variance in growth characteristics of provenances does not specify the suitability of a particular reproductive material for a given area. Slovak provenances even from a relatively small land unit (Šaštín area) planted in the same research plot have different quantitative and qualitative traits. However, the evaluation of the test plots of Scots pine in Bohemia showed impaired growth performance of most of the Slovak provenances. Therefore, it is necessary to test more provenances from a larger area of the Scots pine range to obtain the possibility of using a wider range of reproductive material of the tree in our conditions. In the long term, further provenance trials with new reproductive material are needed to assess suitability under changing natural conditions.

Analysis of erosion hazard level and land rehabilitation pattern with the RUSLE method based on GIS at Wai Tala Watershed in West Seram Regency Maluku Province

This study used the Revised Universal Soil Loss Equation (RUSLE) and Geographical Information System (GIS) to estimate the annual rate of soil loss, map erosion factors, and recommend a suitable pattern of land rehabilitation in Wai Tala watershed, Regency of Western Seram. The research material used in this study were rainfall data for 38 years, Digital Elevation Model Nasional (DEMNAS) Image Map, Rupa Bumi Indonesia (RBI), geology, soil, land use, and watershed boundaries of Maluku Province. Field research was conducted on 187 land units, and each land unit contained RUSLE erosion factors: topography, soil type, and land use. The spatial distribution of erosion factors was processed using the Arc.GIS10.8, and the soil erosion rates were estimated using the RUSLE method, then corrected using the land degradation model developed in small islands in Maluku. The results showed that the level of erosion hazard in the Wai Tala watershed was none to slight (mean = 3.54 t/ha/yr), moderate erosion (21.52 t/ha/yr), high erosion (110.01 t/ha/yr), and very high erosion (252.84 t/ha/yr). The recommended land rehabilitation patterns that can reduce annual soil loss lower than the tolerable limit are maintaining the none to slight erosion areas with the present land uses in particular primary and secondary forests, and with reforestation or agroforestry patterns combined with low to high-density garden plants or with low to high densities cover crop at the moderate to very high erosion areas.

The misconception of soil organic carbon sequestration notion: When do we achieve climate benefit?

AbstractSoil organic carbon (SOC) sequestration is a key function of natural and semi‐natural ecosystems. Restoring this property in terrestrial ecosystems has become central to the EU's climate change mitigation and adaptation strategies. However, SOC sequestration is a widely misunderstood concept. The different methodological approaches used to investigate and compare SOC stock under sustainable agricultural practices play a key role in reinforcing misconceptions about this complex process. This commentary paper aimed not only to provide a clear definition of SOC sequestration, but also to interpret the results that can be obtained for SOC stock change estimation using the SOC stock difference and the paired comparison methods, as well as to identify the soil carbon‐related processes that achieve climate mitigation. SOC sequestration can be defined as the progressive increase in a site's SOC stock compared with pre‐intervention via a net depletion and transfer of atmospheric CO2 into the soil, where it is retained as soil organic matter (SOM), by plants, plant residues, or other organic solids such as the material derived from the organic fraction of farming solid waste, which can be used as a fertilizer (e.g., manure, compost, biochar, and digestate), and that is produced or derived from that land unit. To date, the most appropriate way to determine whether a land unit's soil is a sink or rather a source of atmospheric CO2 is to implement the SOC stock difference method, provided the non‐occurrence of carbon exchange between ecosystems.

Evaluation of land use impact on soil quality in Samaru College of Agriculture, Northern Guinea Savanna, Nigeria

Abstract Land use changes influence soil quality, which is of fundamental importance in sustainable crop production and environmental management. This study evaluated land use impact on soil quality at Samaru College of Agriculture farm, Ahmadu Bello University, Zaria, Nigeria. The land use types were Tomato/Pepper, Grapevine/Fluted pumpkin, Mango/Orange, and Guava/Mango. A profile pit was dug in each land unit. Soil samples were collected from genetic horizons, prepared, and analysed in the laboratory using standard methods. Sand, silt, and clay differed significantly (p < 0.05) among the land uses. The soil texture varied from clay loam to clay. Bulk density (BD) was significantly (p < 0.05) higher under Mango/Orange and Guava/Mango than other land use types. The soil reaction (pH) ranged from 5.0 to 5.8 and was strongly to moderately acidic. Soil organic carbon was low (< 10 g/kg), total nitrogen values of 0.19 – 0.24 g/kg were low, and available phosphorus values of 1.8 – 27.4 mg/kg were rated low to high across the land use types. Soils under the Grapevine/Fluted pumpkin land use type were significantly higher in organic carbon, exchangeable potassium, sodium, and effective cation exchange capacity than the other land use types. Soil quality under Grapevine/Fluted pumpkin was rated best (80 %), whereas soil quality under Tomato/Pepper land use type was the worst (40 %). The soils were low-to-high in quality and had a higher potential to support crop production if management practices that encourage the build-up of nutrients in the soil system were adopted. The application of manure, liming materials, and phosphorus-based fertilisers is advocated.

ANALISIS KORELASI KARAKTERISTIK TANAH (P TERSEDIA, BAKTERI PELARUT FOSFAT, C ORGANIK, DAN KAPASITAS TUKAR KATION) TERHADAP PRODUKTIVITAS JAGUNG DI KECAMATAN CIBUGEL, KABUPATEN SUMEDANG

Maize is the main strategic food crop in Indonesia's food supply, but the productivity of maize in Indonesia is still low. Increasing the productivity of maize can be done by understanding information about the characteristics of the soil on maize planting areas. The research aimed to evaluate the relationship of soil biological and chemical characteristics (available P, phosphate solubilizing bacterial population, arbuscular mycorrhizal fungal population, organic C, and cation exchange capacity) on maize plant productivity. The research was carried out in Cibugel District, Sumedang Regency. The research used descriptive survey and comparative methods on 18 soil samples. The maize planting area was obtained based on analysis and overlapping of land units in the form of; slope, elevation, climate and shelled maize production area. Maize planting land is at an altitude of 500-1,000 meters above sea level and with a slope of 10-30%. The results of correlation analysis showed that organic C, cation exchange capacity, and phosphate solubilizing bacteria had a positive correlation with maize productivity, while available P and arbuscular mycorrhizal fungi had a negative correlation. organic C had the highest close relationship with a value of r = 0.43, while the other parameters have a weak relationship.

EVALUASI STATUS KESUBURAN TANAH DI MASA REPLANTING PERKEBUNAN KELAPA SAWIT PADA TANAH MINERAL PROVINSI JAMBI

Appropriate fertilization recommendations are needed to maximize the production of oil palm plants on land that has been used for a long time. This study aimed to determine the status of soil fertility during the oil palm replanting period in Kemang Manis Village, Muara Papalik Sub-district, West Tanjung Jabung Regency, and determine fertilization recommendations according to the needs of oil palm plants based on soil fertility. This study used a survey method; soil samples taken were disturbed soil samples, and sampling was carried out at two depths, namely 0-30 cm and 30-60 cm. Determination of sampling points using stratified random sampling method based on homogeneous land units that were processed based on soil type and slope in the research location. The collected soil samples were analyzed for H, CEC, BS, organic C, P2O5, K2O, and total N. The results showed low fertility status during the oil palm replanting period in the research location. Observations of the soil profile also showed that the O horizon was thin. Fertilization recommendations that must be made to improve soil fertility include adding dolomite fertilizer to increase soil pH value and increasing the availability of N, P, and K elements in the form of Urea, SP36, and KCl. To increase the content of organic materials in the soil, applying oil palm empty fruit bunches can also improve the soil's physical, chemical, and biological properties.

A Comparative Study of BSE Listed Sectoral Indices of Real Estate and Banking Industry

Purpose: Shareholders are the real owners of the company. They provide capital to the business to get a better return on their investment. Maximizing shareholder wealth has become the primary goal of today's business world. No business entity can become profitable without producing a lot for various investors. There are some strategies to determine the organization productivity and valuation of investors. A cutting-edge form of top management, economic value added (EVA) is a way of valuing shareholder wealth. This helps ensure the true productivity of the organization at the expense of value and capital. The concept was first created by Stern Stewart and Co. The company proposed 164 changes in GAAP rules to calculate real economic profit and some changes in economic capital. MVA is another modern way of valuing shareholder wealth. It describes how efficiently a company uses shareholders' assets. The study made two corrections to the calculation of economic benefit and two corrections to the related population. Real estate and banking companies listed on the Bombay Stock Exchange were selected for the study. The purpose of the audit was to determine the value of investors in BSE-listed land and bank units based on EVA and MVA over a period of five years. Speculations were tested using ANOVA and T-TEST. The audit revealed that an organization like Legend Engine Corp expanded its EVA and MVA during this period. Design/Methodology/Approach: Five BSE listed industries are considered for the present research work and analysed by using EVA and MVA. Findings/Result: A profitable sector is identified. Opportunity is provided for the investors to buy, sell, or hold the stock to generate more profits in the selected sector. It has been observed that SBI has a high typical EVA unlike various banks but it has decreased in the long run. All financial organizations have a positive relationship between EVA and MVA. Originality/Value: Among the organizations in the selected countries, Godrej Properties, and DLF are positively associated with MVA and investment wealth creation every 5 years. Choosing stocks from an industry is a big problem for investors because the market is unpredictable and offers more opportunities for traders and investors to buy sell or hold stocks and earn potential profits in the market. This study aims to compare EVA and MVA to provide some recommendations for stock and industry selection to all investors. Paper Type: Comparative research

Unveiling the Epoch: Exploring Pesticide Utilization and Trade Trends Globally and Regionally from 1990 to 2020

Over the past three decades, a rapid increase in pesticide usage has played a central role in transforming the landscape of modern agriculture. The objective of this research is to conduct a comprehensive analysis of changes in pesticide usage from 1990 to 2020, emphasizing the complexity of global trends, environmental impacts, and pesticide trade dynamics. This study utilizes agri-environmental indicators and relies on the latest statistical data from FAOSTAT in 2022. The applied research method is a quantitative approach based on secondary data.The research findings indicate that global pesticide usage reached 2.7 million tons in 2020, with an average of 1.8 kg/ha. Although reaching a stable level, pesticide trade experienced a significant increase, particularly in the disinfectant category. Over the past three decades, there has been an approximately 50 percent increase in pesticide usage, especially in herbicides. Per capita analysis shows a relatively stable consumption rate, although there is an increase in pesticide usage per unit of agricultural land. Regional levels reveal significant disparities, with Asia as the largest contributor, Europe implementing strict policies, the Americas having the highest usage rates, Oceania experiencing low trade, and Africa applying low usage rates. Some countries, such as Saint Lucia, exhibit high pesticide application rates per unit of agricultural land, and this variation requires in-depth analysis to understand influencing factors. To mitigate negative impacts, international cooperation, the development of sustainable technologies, and a profound understanding of pesticide applications are necessary. Therefore, more effective and sustainable agricultural policies need to be designed to protect the environment and human health.

Evaluasi Kesesuaian Lahan untuk Tanaman Jagung (Zea mays L.) di Kecamatan Dulupi Kabupaten Boalemo

Dulupi is one of the districts in Boalemo Regency which is a center for maize production, but the high intensity of maize cultivation causes a decrease in the quality of the local land. This research aimed to determine the land suitability classes and limiting factor for maize (Zea mays L.). The research was carried out in Dulupi District of Boalemo Regency from September to Desember 2022. It employed a data matching method, matching the data for each land unit with suitability criteria. The findings revealed that the level of the land suitability for maize in Dulupi District, Boalemo Regency had theree classes of land suitability, namely moderately suitable (S2) of 88% (6314,54 Ha), marginally suitable (S3) of 10% (763,89 Ha), and not suitable (N) of 2% (41,15 Ha). In contrast, the yield-limiting factors were nutrient retention, avaible nutriens (N, P, K), erosion hazard, drainage, and effetive depth. With the improvment efforts, the yield limiting factors in the potential land and suitability increased to S2 and S3 classes.

The weight and size of and fruits were more when intercropped with bajra and maize in comparison to K. mandarin E. lemon sole fruit trees. The multipurpose trees on the border areas of the farm helped to save land and increase cropping area

Indexing and segment-level mapping of soil quality in a spatially complex watershed in northern Iran.

Soil quality (SQ) modeling and mapping is a leading research field aiming to provide reproducible and cost-effective yet accurate SQ predictions at the landscape level. This endeavor was conducted in a complex watershed in northern Iran. We classified the region into spectrally and topographically homogenous land units (average area of 48 ± 23ha) using object-based segmentation analysis. Following the physicochemical analysis of soil samples from 98 stations, the Nemoro soil quality index (SQIn) was produced using the minimum dataset procedure and a non-linear sigmoid scoring function. SQIn values averaged 0.21 ± 0.06 and differed statistically between major land uses. To predict and map SQIn for each land unit, the best-performing regression model (F(3, 84) = 45.57, p = 0.00, R2 = 0.62) was built based on the positive contribution of the mean Landsat 8-OLI band 5, and negative influence of land surface temperature retrieved from Landsat 8-OLI band 10 and surface slope (t-test p-values < 0.01). Results showed that dense-canopy woodlands located in low-slope land units exhibit higher SQIn while regions characterized by either low-vegetation or steep-sloped land units had SQ deficits. This study provides insights into SQ prediction and mapping across spatially complex large-scale landscapes.

Perbuatan Melawan Hukum Oleh Badan Pertanahan Nasional Terkait Sertifikat Pengganti Hak Milik Atas Tanah

Land registration is a government task carried out in order to ensure legal certainty in the land sector (a "Rechts Kadastre" or "Legal Cadastre"). The purpose of land registration is stated in Article 3 of Government Regulation Number 24 of 1997. To achieve this orderly administration, every plot of land and apartment unit including transfer, encumbrance and write-off must be registered in Government Regulation Number 24 of 1997. Article 1 paragraph (20) states: "Certificate is a certificate of proof of rights as intended in Article 19 paragraph (2) letter c UUPA for land rights, management rights, waqf land, ownership rights to apartment units and mortgage rights, each of which has been recorded in the relevant land book.&#x0D; The method used in this research is a normative approach and a Socio Legal approach which originates from collecting data obtained from primary data and secondary data, then analyzed using qualitative analysis methods.&#x0D; The results of this research answer that the form of unlawful action by the National Land Agency regarding land ownership certificates based on Decision Number 169/Pdt.G/2022/PN.Tjk is not carrying out community requests regarding Government Regulation Number 24 of 1997 concerning Land Registration Article 57 paragraph (1) which explains that at the request of the right holder a new certificate is issued as a replacement for a certificate that is damaged, lost, still uses a blank certificate that is no longer used or that was not handed over to the auction buyer in an execution auction. Meanwhile, the analysis of the judge's considerations regarding unlawful acts by the National Land Agency regarding certificates of ownership of land based on Decision Number 169/Pdt.G/2022/PN.Tjk is from a normative aspect because Certificate of Ownership Number 926/Kd, issued on May 9 1977, is located in Sukarame Village, Kedaton District, Bandar Lampung City with Measurement Letter Number 2931/1977 dated 7 February 1977 with an area of 8,400 (eight thousand four hundred) square meters in the name of Purwanto, which is a legal product of State Administrative Officials and is owned by the Plaintiff based on a gift from his parents.

Environmental impact of grass-based cattle farms: A life cycle assessment of nature-based diversification scenarios

Diversification is widely considered to positively influence the environmental sustainability of livestock farming. Multiple options exist to diversify cattle farms, but few have been examined at a systems level for grass-based livestock farms. Three nature-based diversification options recommended for livestock farms were examined in this study: mixed grass–white clover swards (GWC), organic farming (OFS) and agroforestry (AGF). They were applied on dairy and suckler calf-to-beef farming systems common in the Republic of Ireland. Both of these bovine systems were evaluated over a 3-year period (2017–2019) and were nationally representative. The environmental impact and resource use of dairy and suckler calf-to-beef systems were modelled using life cycle assessment (LCA). The system boundary of the LCA model extended from the extraction of raw materials to the sale of milk and cattle from the farm, i.e. cradle to farm-gate. Six of the major environmental impacts of cattle farming were simulated; global warming potential (GWP), non-renewable energy (NRE) depletion, land occupation (LO), acidification potential (ACP), freshwater and marine eutrophication potential (FEP and MEP). Impacts were scaled to the following functional units: land area, fat and protein corrected milk (FPCM) for dairy and carcass weight (CW) for beef. The result illustrated that GWC swards reduced the GWP of milk production by 9% and cut the GWP of beef LW by 3%. Per unit of product, this strategy decreased ACP by 4%–5%, NRE depletion by 13%–19% and LO by 6%–7%. However, it increased MEP by 5%–12% due to clover fixing more N than it replaced. Cattle farms based on GWC were more productive than conventional farms, but tended to increase impacts per hectare. Organic farming had the lowest environmental impacts per unit of land and reduced GWP and NRE depletion. Without carbon sequestration, organic farming had the opposite effect on GWP of FPCM and increased ACP and MEP per product unit. Declines in productivity in organic systems led to the rise in these impacts per unit of product and increases in LO relative to conventional systems. Partial conversion (10%–20%) of grassland to silvopasture decreased milk and beef output, and slightly improved environmental performance. Carbon sequestration was greater in silvopasture than in grassland, albeit LCA models struggle to accurately quantify the influence of management change on this process. This issue can be overcome through more field and modelling research on sequestration. Further research is also required on combining diversification options to optimise the environmental sustainability of cattle farming.

Study on the Trade-Offs of Land Functions in the Central Plain of China for Sustainable Development

Properly managing the relationship between food security, ecological protection, and urbanization, and coordinating the trade-offs among these three factors for land demand are extremely important for environmental management and sustainable development. In this study, we attempt to analyze the state of land use trade-offs from a dynamic perspective in terms of both potential and efficiency. We have innovatively proposed a new land use trade-off analysis framework integrating the Estimation System for Land Productivity (ESLP) model, machine learning algorithms, ecosystem service value assessment, and spatial analysis method. By applying the framework, the potential and efficiency of the three land use functions of urban development, ecological protection, and agricultural production on the Huang-Huai-Hai (HHH) Plain were comprehensively estimated, and the trade-off relationship between the three land use functions was identified. The results showed a prominent conflict between urban development and agricultural production (around 8%) on the HHH Plain, especially in the Beijing–Tianjin–Hebei urban agglomeration and the southern Jiangsu urban agglomeration. In the mountainous areas, such as northern Hebei and central Shandong, there was an obvious trade-off between ecological land and agriculture land. Most cities had a trade-off between ecological land and urban land (approximately 6% of the study area), but it was relatively more relaxed in comparison. Finally, we found that on the HHH Plain, where land resources are fiercely competitive, spatial planning and land resource control depend not only on the suitability or potential of the land unit, but also on whether the efficiency of land use has reached an appropriate range. The smart way to use land resources is to scientifically trade-off different land use functions and improve the efficiency of land use to achieve maximum benefit.

AGRICULTURAL LAND AND FORESTRY ZONATION AS DISASTER MITIGATION EFFORTS TO DAS KAONISIK DISTRICT, DISTRICT TINGGIMONCONG GOWA

Determination of land for the development of agricultural and forestry crops important to know as mitigation in the watershed Kaonisik Tinggimoncong Gowa district in South Sulawesi. Based on land suitability and productivity data supporting the use of land for agriculture and forestry crops on some land units. Land suitability classes determined by laboratory and field test results on a number of land characteristics that are matched to the criteria of the guidelines to grow plants with CSR/FAO staff (1983). Land mapping unit is the smallest unit that is used as the evaluation unit, obtained through remote sensing interpretation, analysis, topographical maps, geological maps, soil maps, land use, slope and soil, passed penampalan (overlay) to acquire land units map. The results showed that: 1) land suitability classes for agricultural crops; corresponding marginal (S3) 12 land units: 1450 ha (38.5%), does not match the current (N1) 1 unit area: 80.5 ha (2.2%), and not suitable permanent (N2) 11 land units: 2094 ha (59.3%). The limiting factor is the dominant medium roots (r), nutrients available (n), and terrain (s), while for forest plants: as marginal (S3) 8 units of land: 952 ha (24.9%), it is not appropriate at this time (N1) 6 unit of land: 644 ha (17.7%), not suitable permanent (N2) 10 land units: 2029 ha (57.4%). The limiting factor is the dominant medium roots (r). 2) Agihan sub-class of land suitability potential (S3rns) for the coffee plant in the village of Jonjo, Baliti, Majannang, Borong Bulo, Laloasa, Bangkitonro, Bontopanno, Gallang, with an area of 1450.5 ha Pattiro (38.5%), according to the plant sengon marginal (S3ns) Majannang village, Borong Bulo, Jonjo, Laloasa, Tonrokombang, and Manimbahoi with an area 952 ha (24.9%).

Eco-efficiency analysis of rainfed and irrigated maize systems in Bosnia and Herzegovina

Abstract This study evaluated the eco-efficiency of rainfed and irrigated maize production in Bosnia and Herzegovina. Environmental impact assessments were performed through energy, carbon footprint, and water scarcity footprint analysis. For economic analysis, gross and net returns and benefit–cost ratios were calculated. Eco-efficiency was measured by the ratio between the net return and environmental criteria. The findings indicate that the transition from rainfed to irrigated maize cultivation per unit of land results in a 53.7% higher yield and gross value of production, but also a 69.8% increase in energy input, a 22% rise in greenhouse gas emissions, and a 3.6-fold increase in the water scarcity footprint. While a positive link exists in irrigated maize between higher yield and lower carbon footprint per unit of product, rainfed systems outperform in energy efficiency, productivity, profitability, water scarcity footprint, and overall eco-efficiency. Both systems rely heavily on nonrenewable energy sources, with fertilization (affecting energy and carbon footprint), mechanization (affecting carbon footprint), and irrigation (exacerbating water scarcity) as the main contributors to the negative environmental impacts. The implementation of optimization strategies for these inputs is of paramount importance to reduce environmental impacts and promote sustainability in maize farming in Bosnia and Herzegovina.

Land suitability assessment for rapeseed potential cultivation in upper Tigris basin of Turkiye comparing fuzzy and boolean logic

Assessment of land suitability is a prerequisite for the conservation and maintenance of land productivity and the improvement of land use and management systems. This study assessed land suitability for rapeseed (Brassica napus L.) production using topography, climate, and soil data by analytical hierarchy process (AHP) and the Mamdani Fuzzy Inference System (MFIS). The study area covers 3737 km2 of land in the Diyarbakir province of southeastern Turkiye. The weights of topography, soil and climate factors in AHP were determined by expert opinions and the information in related literature. They were included in the whole process, mainly membership functions and rule base stages in the MFIS. The highest weighted factor was slope (0.264), followed by altitude (0.121), annual average temperature (0.114) and soil texture (0.112). The MFIS-based land suitability assessment indicated that the proportions of moderately (S2), marginally (S3) and currently not suitable (N1) land classes in the study area were 71.35%, 18.75% and 9.9%, respectively. The AHP results showed that 98.94% of the land was S3, and 1.06% was N1. The compatibility of AHP and MFIS methods in N1 land units was 96.05%, while the agreement for S2 and S3 land classes was not sufficiently high. The suitability of rapeseed cultivation has been more sensitively assessed by the fuzzy continuous classification obtained by the MFIS method.

Biomass production, carbon stock and sequestration potential of prominent agroforestry systems in north-western Himalaya, India

Agroforestry is an age-old practise of integrating farming with practises, preferably on the same unit of land on sustainable basis. There is tremendous scope for Agroforestry because India has achieved self-sufficiency in food production. Now its attention is becoming more focused on the ecological problems and shortage of fuel, fodder and other outputs as well as unemployment. So, agroforestry land use systems offer a better option by serving as carbon sinks and contributing in attaining food safety, subsistence income, and habitat amelioration. The current study was conducted in this context in the south Kashmir area of India with the objective of recognising the capability of various agroforestry systems for biomass estimation and carbon sequestration assessment for mitigating climate variation. The present study entitled “Biomass production, carbon stock and sequestration potential of prominent agroforestry systems in North-western Himalaya, India” was carried out, during 2018–2019. The study site is located between 33° 72’N and 75° 14’E at an altitude ranging from 2,900 to 5,900 M (amsl). Multistage random sampling technique was used for selection of sampled tehsils, blocks, villages and farmers in Anantnag district. The first stage was the random sampling of six tehsils namely Anantnag, Shangus, Kokernag, Dooru, Sallar, and Larnu and blocks per tehsil namely, viz.; Anantnag, Shangus, Sagam, Shahabad, Pahalgam and Larnu. Then four villages within each block like Anantnag (Ruhoo, Dialgam, Wanihama and Donipawa), Shangus (Shangus, Nowgam, Kutheir and Andoora), Sagam (Hiller, Khalhar, Sagam and Bidder), Shahabad (Larkipora, Shankerpora, Nathipora and Bragam), Pahalgam (Yanner, Charigam, Movra and Wahdan) and Larnu (Leesu, Dandipora, Bidhard and Larnu). Ten farmers within each village were selected, thus making a total of 240 farmers, which accounts 25% sampling intensity. Four agroforestry systems including horti-agriculture, agrisilviculture, (boundary planting), agri-horti-silviculture and horti-silvipasture were chosen for the study as the experimental configuration. Maximum biomass was found in horti-silvipastoral contributing 66.55 t ha−1 followed by agri-horti-silviculture as 50.18 t ha−1, horti-agriculture as 36.22 t ha−1 and agri-silviculture as 34.87 t ha−1. The maximum mean biomass of fruit trees (30.54 t ha−1), forest trees (25.19 t ha−1), grass (7.18 t ha−1) during the first cut and 3.64 t ha−1 during the second cut, was calculated in horti-silvipasture system. The overall biomass output of diverse agroforestry systems goes along with the sequence: horti-silvipasture &amp;gt; agri-horti-silviculture &amp;gt; horti-agriculture &amp;gt; boundary plantation, respectively. As a result, estimates of carbon stocks and carbon sequestration for all systems showed the same trend as values for biomass since they are both directly related to the capacity for biomass generation of various plant components. By providing for rural livelihoods and serving as an efficient carbon sink through carbon sequestration, these agroforestry systems in the Himalayas can significantly increase total production and productivity. The results of the current study could have a big impact on how alternative agroforestry systems and tree combinations are chosen for efficient carbon budget management in delicate Himalayan ecosystems.
