Remote sensing for rangeland conservation monitoring: Impacts of livestock removal after 15 years

Abstract Degradation from overgrazing of global arid rangelands is of significant concern for this widespread terrestrial ecosystem, and the people who rely on its sustainable use. Addressing this degradation requires a better understanding of how livestock removal and conservation management actions affect the rehabilitation of land condition. However, the dominant effect of climate and meteorological variability on arid vegetation makes isolating management‐induced change a difficult task. We present an analytically simple method for measuring relative land condition by assessing differences in remote‐sensing‐derived persistent fractional vegetation between adjacent stocked and destocked regions over time. The 22‐year observation period focusses on vegetation recovery at a long‐established sheep station after the removal of livestock and the introduction of conservation‐focussed management. The study region, in the southern Australian arid rangelands, comprises sparsely vegetated chenopod shrublands and acacia woodlands across low‐lying plains. Comparison is made to immediately surrounding stocked properties in a spatial design where climate and biogeographic variables remain consistent across the study area. We found an unequivocal relative increase in vegetation cover, and reduction of bare ground cover at the destocked property that became evident approximately 8 years after a reduction in grazing pressure. Distinctly higher persistent vegetation cover was maintained, even during periods of drought. Non‐photosynthetic vegetation cover was most indicative of long‐term change and increased by 1.1% relative to surrounding areas. Photosynthetic vegetation cover increased by 0.5%, while bare ground cover decreased by 2.1%. These cover changes, particularly in the non‐photosynthetic vegetation and bare ground components spatially coincide with the fenced boundary of the destocked property. Synthesis and applications: The ability to quantify management‐related impacts in land condition using freely available remote sensing data could support improved management by all stakeholders in these regions. The method leverages readily available satellite remote sensing data in a study design that is not dependent on large geospatial and climatic datasets that are not necessarily available in remote regions.

Biophysical Resource Characterization, Identification and Prioritization of Major Constraints and Potentials of Gara Ebanu Community Watershed in Sululta District, Ethiopia

Baseline characterization helps to understand the initial livelihood condition of the people in the watershed before and after the intervention of the project to measure the amount of change attained by the project. The objective of the study was to characterize baseline information on the existing biophysical resource used as benchmark for planning and impact monitoring and to identify and major constraints and potential in the watershed. The watershed was selected depending on agro-ecological representation, prevalence of resource management and land degradation problems and accessibility for intensive follow-up. Based on the preliminary outlet identified during the watershed selection process, the watershed boundary was delineated using GPS data and the map of watershed was geo-referenced and digitized for its contour, roads, rivers, and other features. Both primary and secondary data were used for the study and primary data was collected through field observation, household survey, focus group discussion and interview of the key informants. From the total 103 household heads living in the watershed, 62 household heads were selected as a respondent for the study. The collected data was managed and analyzed using Statistical Package for Social Sciences (SPSS) and Microsoft excel 2010. The results of the study showed that about 29.4% of the watershed slope was characterized by flat lands, 45.7% moderate slope and 24.9% steep lands. As well as soil fertility status of cultivated land in the watershed were 33.9% low, 55.9% moderate and 10.2% high. The results of the study showed that the major constraints identified by sampled household heads were decline of soil fertility, soil erosion, climate change, land shortage, and deforestation were significantly contributed to the low crop yield in the watershed. About 27.4% of the sampled households had encountered decline of soil fertility problems, 25.8% of sample farmers encountered soil erosion problem, and 22.6% of sample farmers encountered climate change problem in the watershed. From the identified major constraints, the highest priorities were given for decline of soil fertility, soil erosion problem, shortage of feed and fodder, and decline of crop productivity respectively. In the watershed, immediate short-term actions should be taken particularly participatory integrated watershed management were recommended.

Dynamics modeling of a three-legged sea floor drill rig hard-landing and analysis of influence of landing conditions on its responses

Touchdown is a decisive step in the underwater deployment of the sea floor drill rig (SFDR), but the related research is still in its infancy. Therefore, a spatial seven degrees of freedom (DoF) dynamic model of the three-legged SFDR "Seabull Ⅱ" hard landing was established, and a simulation platform was built. In addition, the influence of landing conditions on the dynamic responses was understood through orthogonal simulations, which indicates that: (a) The maxima of outrigger axial-force-loads are mainly affected by the sediment elastic coefficient; the maximum of connecting strut lateral-force-load is mainly affected by the slope of the landing surface (SLS). (b) The acceleration-load is not a point that requires special attention for SFDR hard landing. (c) For control strategies, it is recommended to set the release height from seabed (RHFS) at 2–3 m, and to choose a smaller leg-opening-angle (LOA) based on the actual sea condition and seabed environment. (d) For the optimal design of the SFDR supporting system, it is advisable to increase the friction coefficient between the footpad and sediments by changing the structure and surface characteristics of the footpad, as well as to add a function of variable support area to the footpad.

Terminal Soft Landing Guidance Law Using Analytic Gravity Turn Trajectory

This paper presents an innovative terminal landing guidance law that utilizes an analytic solution derived from the gravity turn trajectory. The characteristics of the derived solution are thoroughly investigated, and the solution is employed to generate a reference velocity vector that satisfies terminal landing conditions. A nonlinear control law is applied to effectively track the reference velocity vector within a finite time, and its robustness against disturbances is studied. Furthermore, the guidance law is expanded to incorporate ground collision avoidance by considering the shape of the gravity turn trajectory. The proposed method’s fuel efficiency, robustness, and practicality are demonstrated through comprehensive numerical simulations, and its performance is compared with existing methods.

Molecular Dynamics Simulations of Soft and Reactive Landing of Proteins Desorbed by Argon Cluster Bombardment.

Reactive molecular dynamics (MD) simulations were conducted to investigate the soft and reactive landing of hyperthermal velocity proteins transferred to a vacuum using large argon clusters. Experimentally, the interaction of argon cluster ion beams (Ar1000-5000+) with a target biofilm was previously used in such a manner to transfer lysozymes onto a collector with the retention of their bioactivity, paving the way to a new solvent-free method for complex biosurface nanofabrication. However, the experiments did not give access to a microscopic view of the interactions needed for their full understanding, which can be provided by the MD model. Our reactive force field simulations clarify the landing mechanisms of the lysozymes and their fragments on collectors with different natures (gold- and hydrogen-terminated graphite). The results highlight the conditions of soft and reactive landing on rigid surfaces, the effects of the protein structure, energy, and incidence angle before landing, and the adhesion forces with the collector substrate. Many of the obtained results can be generalized to other soft and reactive landing approaches used for biomolecules such as electrospray ionization and matrix-assisted laser desorption ionization.

Investigating smallholder farmers’ practical experiences, perceptions and response to climate change: An empirical analysis in Cameroon

Climate change is constraining rural wellbeing, agriculture and food security. This necessitates adaptive strategies to overcome negative effects especially at the level of low-income tropical farming households. Using survey data from farming households in the Western Highland and the Bimodal Rainfall Humid Forest agro-ecological zones in Cameroon, this study evaluates the socio-economic and institutional factors associated with farmers’ perception and adaptive response to climate variability and change. We employed a logistic regression model to estimate the drivers of farmers’ perception. Our results show that farmers’ experience and land status (ownership) are positively associated with farmers’ ability to perceive climate change in the Western highlands agro-ecological zone. Access to credit, membership in a farmers’ organisation and gender are significant drivers in the Rainforest agro-ecological zone. Our findings show that different socio-economic and institutional factors drive perception and these factors differ between zones. The findings have important implications for short-term adoption of coping strategies and medium-term adaptation planning. We suggest that farmers’ capacity is improved through early-warning climate information and the creation of farmer field school to vulgarise climate smart farming techniques and supplemented with timely technical support from the governmental extension services.

IDENTIFIKASI LAHAN KRITIS SKALA 1:25.000 BERBASIS CITRA SENTINEL 2 DAN DEMNAS RESOLUSI 8 METER (STUDI KASUS SUB DAS CIKAPUNDUNG JAWA BARAT)

Critical land is a condition of land that is no longer able to carry out its functions properly because it has experienced physical, chemical, and biological damage. One area that has the potential to experience critical land problems is the Cikapundung Sub-watershed, West Java. This research aims to identify the existence of critical land in the Cikapundung Sub-watershed area by integrating the Geographic Information System, Sentinel-2 Imagery, and DEMNAS as well as mapping the distribution of land criticality levels in the Cikapundung Sub-watershed at a detailed scale (1:25,000). The research was carried out from May to August 2023. The research was carried out using spatial analysis methods by overlaying thematic maps of each critical land parameter consisting of maps of land cover, erosion, and slope. The results of overlaying all critical land parameter maps were then analyzed using a scoring method to classify the level of land criticality and create a critical land distribution map in the Cikapundung Sub-watershed area. The results of identifying critical land in the Cikapundung Sub-watershed area produced five classes of land criticality, namely uncritical, potentially critical, rather critical, critical, and very critical. The identification results show that there are 4210.94 ha (13.83%) of land identified as critical land in the Cikapundung Sub-watershed area. The results of mapping the level of land criticality in the Cikapundung Sub-watershed show that the Cikapundung Sub-watershed area which is included in the forest area is dominated by the moderately critical land criticality class, while the Cikapundung Sub-watershed area which is outside the forest area is dominated by the uncritical land criticality class.

Daughters and Inheritance: Babylonian Boundary Stone 9 and Numbers 27

Abstract A daughter’s ability to inherit property is treated differently in various ancient Near Eastern cultures. This paper examines the difference between land inheritance by daughters in Israel and Babylon using the text of Numbers 27 and Babylonian Boundary Stone 9. The unique status of land and land allotment in the two societies are explored as well as the implications for the status of daughters. The conclusion from the comparison is that the biblical text excludes daughters because of limited landholdings and the desire to maintain the property inheritance from the initial land allotment event. However, Babylonian Boundary Stone 9 allows daughters to inherit more easily because of fluid landholdings and multiple (royal) land allotment events.

Improvement of superior soybean variety, Biosoy-1 for aluminium tolerance character

Abstract Indonesia has lot of sub-optimal land, especially outside Java, but generally the land is acidic, contains lots of heavy metals and is poor in nutrients, making it less suitable for agriculture, including soybean cultivation. Efforts to improve land conditions through the application of liming are quite helpful, but are inefficient because they are easily washed out by rainwater and require expensive labor and costs for large areas. The use of tolerant and adaptive varieties for acidic land are effective solutions. Biosoy-1 and Biosoy-2 are new superior soybean varieties released by Ministry of Agriculture which have high yield potential (more than 3 tons/ha) and big grain, but are less adaptive to sub-optimal land so that the planting area is still limited. Efforts to improve the Biosoy variety for aluminum stress tolerant have been carried out through the introgression of the MaMt2 gene from transgenic soybean lines into the Biosoy variety. Thirty of F1 soybean seeds have been produced and 24 plants of them were positive for carrying the MaMt2 gene. Furthermore, the F1-MaMt2 plants were backcrossed to Biosoy several times in order to obtain a soybean line with high yield and tolerance to aluminum stress. Currently, a total of 16 number of BC3F1 seeds are being planting in confined screen house for molecular analysis and following by backcrossing to Biosoy-1 variety to produce BC4F1 seeds.

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.

Analysis of Carbon Flux Characteristics in Saline–Alkali Soil Under Global Warming

ABSTRACTThe carbon cycle of saline–alkali ecosystems will be affected to some extent in the context of future global warming. Therefore, we investigated the net ecosystem exchange (NEE) of three typical crops (wheat, maize and soybean) in the saline–alkaline land of the Yellow River Delta. To further investigate CO2 fluxes, NEE was decomposed into gross primary productivity (GPP) and ecosystem respiration (Re). In terms of seasonal variation, wheat and soybean were carbon sources in the early and late growth periods, and carbon sinks in the rest of the period, whereas maize was a carbon sink in the majority of the period, and maize had good carbon sink potential. The cumulative NEE during the growth periods for wheat, maize, and soybean were 414.86, 258.24 and 228.92 g cm−2, respectively, and the daily variation showed that the peak NEE values for the three crops preceded the peak values of both GPP and ecosystem respiration, occurring approximately at 12:00 a.m. In the correlation analysis, NEE and GPP of the three crops were well correlated with photosynthetic photon flux density and net radiation, whereas Re was significantly correlated with air temperature. Through a comparative analysis of CO2 fluxes within various agricultural ecosystems, our findings indicated that wheat demonstrated moderate carbon sequestration capabilities, whereas maize and soybean exhibited strong carbon sink characteristics. Notably, saline–alkali crops exhibited lower Re, whereas GPP levels remained at a moderate range. Therefore, under the global warming trend, the respiration of saline crops and soils will be affected and may change the original carbon sink into a carbon source. Hence, implementing suitable measures targeting saline–alkali areas, such as the establishment of an effective crop rotation system and the enhance saline–alkali land conditions, can reduce emissions of greenhouse gases, thus reducing the pressure of global warming and maintaining a stable carbon cycle in saline–alkali land.

סוגיית העדפת בני המקום בהקצאות קרקע למגורים בסוגי יישוב שונים בישראל

The question of who has the right to reside in a particular locality has been at the center of public and legal discourse in Israel for many years. This is the result of official and unofficial mechanisms intended to exclude certain individuals or groups. This article deals with a related though different issue, which focuses on the preference given to locals during the allocation of state land. Addressing this question requires a discussion of issues such as individual freedom, the meaning of home, the importance of family, the significance of residency in a particular place, the nature of various types of settlements in Israel, justice in land distribution and the necessity of correcting of historical wrongs versus the perpetuation of existing social stratification, as well as the preservation of existing communities versus concerns about pushing them out of a neighborhood or settlement. After presenting a framework for thinking about the issue of preference of locals, the article conducts a critical examination of the existing legal framework in Israel in both rural areas, where the right of residency is managed by cooperative associations, and urban areas, which include, for this purpose, the settlements of minorities. The conclusion drawn from this analysis is that the same flaws in legal decision making with respect to acceptance by a settlement also exist in the regulation of the preference for locals. The social and economic outcomes that affect the lives of individuals and the distribution of land in Israel perpetuate established ways of thinking about forms of residency and about disparities and social differentiation in Israel.

Status of Land Carrying Capacity for Agricultural and Environmental Sustainability in the Nusa Penida Tourism Area

Land resources are very important in supporting tourism activities. As a developing tourism area, Nusa Penida requires sufficient land resources. The increasing population and tourists have triggered new activities affecting land use patterns, negatively impacting land availability and agricultural sustainability. This study aims to calculate the availability, needs, and status of land-carrying capacity to support the sustainability of agriculture in the Nusa Penida Tourism Area until 2028. The research method uses a quantitative approach by collecting primary data obtained directly in the field, secondary data originating from previous research, and data originating from official sources. The result of the calculation of land requirements based on the ecological footprint is the number of inhabitants multiplied by the ecological footprint (gha/capita); the land requirement for 2020 is 49,849 people multiplied by 0.36958702, which is 17,724.283 hectares, while the availability of land in Nusa Penida is 9,894 hectares. This shows that the carrying capacity of land in Nusa Penida has exceeded the threshold or a deficit of 7,830.283 hectares. The area of land in Nusa Penida reaches 20,284 hectares. In contrast, the availability of land in Nusa Penida is based on calculations using the actual production of each type of commodity and the price of rice at the producer level, the unit price of each commodity at the producer level, and the productivity of rice in Nusa Penida is only 9,894 hectares. The projection of land needs until 2028 is 24,640 hectares, so the land carrying capacity in Nusa Penida is a deficit. The results of the calculation of land requirements based on the ecological footprint are 14,746.283 hectares, while the availability of land in Nusa Penida is 9,894 hectares. This shows that the land carrying capacity in Nusa Penida has a deficit of 12,374.283 hectares.

Growth, Yield and Uptake of P Four Variety Soybeans on Biocomposted Coastal Lands

Soybeans (Glycine max (L.) Merrill) are a popular food commodity in Indonesia, but domestic production is still insufficient to meet the demand. To increase production, planting superior varieties on coastal land could be a viable solution. Despite the challenging biological, physical, and chemical conditions of coastal land, nutrients such as phosphorus (P) are crucial for enhancing production. Typically, the phosphorus content in the soil is lower than that of nitrogen (N) and potassium (K), and the ability of soybean plants to absorb phosphorus varies among varieties. This research aims to compare the growth, yield, and phosphorus uptake of four soybean varieties on biocomposted coastal land. The study was conducted using a Randomized Complete Block Design (RCBD) with a single factor consisting of four soybean varieties: Wilis, Anjasmoro, Malika, and Detam 1. The results indicate that the Anjasmoro, Wilis, Detam 1, and Malika varieties exhibit similar responses in phosphorus absorption. However, the Anjasmoro and Wilis varieties demonstrate better adaptability compared to Malika and Detam 1, as evidenced by their superior growth and yield. This suggests that Anjasmoro and Wilis have a higher capability to adapt to the challenging conditions of coastal land. Therefore, these two varieties are recommended for cultivation in coastal areas to boost soybean productivity, ensuring the sustainability and stability of the national food supply.
