The document describes using systematic field surveys across diverse landscapes to assess the effects of land use on soil health. Specifically, it discusses using a standardized Land Degradation Surveillance Framework (LDSF) to collect plot and subplot data on vegetation, erosion, soil properties, and land use history from over 320 sites. This data can then be analyzed using multi-level modeling to understand relationships between inherent soil properties, land cover types, and indicators of soil health across sites. The goal is to explore these linkages and assess how land use influences soil health while accounting for inherent soil constraints.

This study evaluated the effects of inoculating mesquite (Prosopis laevigata) seedlings with the mycorrhizal fungus Glomus sp. and applying different doses of organic matter on plant growth over 180 days in two soil types. The treatments significantly affected most measured variables. Inoculation with Glomus sp. and application of organic matter generally had positive effects on plant height, branching, root growth, and biomass. Significant interactions were found between the treatments. The soil type mainly influenced aboveground growth. The results indicate that inoculating mesquite with Glomus sp. and adding organic matter can promote plant development in arid soils.

Transformation of Australia’s vegetated landscapes. Richard Thackway ACEAS Gr...aceas13tern
The document describes a system called VAST-2 for tracking changes in native vegetation condition in Australia over time due to human activities. It uses a standardized set of ecological criteria and indicators to assess vegetation at sites being transformed by land management practices compared to reference sites. A case study applies VAST-2 to track changes in sand dune vegetation before, during, and after sand mining. The system can help land managers and ecologists understand landscape transformation and has potential applications for monitoring outcomes of activities like environmental restoration.
Ecophysiological Yield Components In Wheat Cultivars Under Variable Phosphoru...Agriculture Journal IJOEAR
Abstract— Effects of P deficiency and interactions Cultivar x P available, on wheat yield and ecophysiological components were analysed, considering that the grain number m-2 is the product of the length of spike growth period, crop growth rate during this phase, the proportion of growth for spikes (partitioning) and spike fertility (grain number produced per unit of spike dry weight). Four cultivars with different strategy to generate yield (i.e. combinations of ecophysiological yield components) were compared with and without P fertilization, during two years in Azul, Buenos Aires, Argentina. The soil was moderately P deficient (7-9 mg P kg-1 soil) and P fertilization treatments (50 kg P ha-1) were established at sowing. P deficiencies affected yield and most of its components, the exceptions were: partitioning to spike, spike growth period and radiation use efficiency. The interaction Cultivar x P fertilization was not significant in all cases. The lack of interaction between cultivar and P level suggest that improvements in any crop physiological component will express in both, moderately deficiencies or high P environment.
Framework for assessing and reporting resilience of native vegetationRichard Thackway
A framework is presented that is relevant to all terrestrial ecosystems and their modification states. Unpinning the framework is the tool's ability to track change and trends based on assessing effects of land management regimes. Effects of these regimes on criteria & indicators of function, structure and composition are scored using criteria and indicators. Changes in condition, resilience and transformation are assessed relative to fully natural a reference state for each plant community. Assessments are constrained to soil landscape units because this approximates to land manager’s use and management of the landscape. The framework helps decision makers assess and report change at sites and landscapes due to human management and natural drivers.
Quantifying the relative impact of physical and human factors on the viticult...Agriculture Journal IJOEAR
— This work assesses the relative importance of the terroirs factors: climate, soil and the relation source-sink, on the vegetative development, yield, berry composition and plant sanitary status. The study was carried out between 2011 and 2014 in nine vineyards from six viticultural regions over the coast of Río de la Plata (Uruguay). The cultivar studied was Tannat, vertically trellised and north-south oriented. The year effect refers to climate, which was characterized using solar irradiation and three indices. The soil was characterized using pits and physico-chemical analyses, to determine three textural categories and to define soil depth and water availability. The source-sink relationship referred to four categories of relations between leaf surface and yield per vine. Statistical analyses included a Mixed Model with random effects to determine the relative importance of each factor to the total variability within the dataset. Total yield per vine was explained by the source-sink relationship, the year and their interaction, both linked to the rainfall amount occurred during the maturation period. The synthesis of primary compounds in the berries was more dependent on the year and the interaction of soil and year with the source-sink relationship. Secondary compound concentrations in the berry depended mainly on the source-sink relationship and climate. This study represents a significant advance to the knowledge of grapevine adaptation to the Río de la Plata terroirs, assigning a fundamental role to the vine grower actions. The growers can modulate grapevine balance as a function of the environment.

The inevitable effects of climate change in the agriculture sector are easily underestimated by agencies and stakeholders, having no means of quantifying them. For these effects to be accurately estimated, a system or method for calculation of the effects is needed. This paper addresses the problem through suitability modeling using GIS to evaluate the suitability of four primary crops like banana, coffee, pineapple and peanut using the relevant variables of slope, elevation, soil, land cover, rainfall, and temperature under RCP 4.5 scenario in municipalities of Amulung, Camalaniugan and Gonzaga, Cagayan, Philippines. It further investigated the suitability of the areas when hazards like flooding and landslide were considered. Results of suitability modeling revealed that pineapple is the most suitable followed by peanut, coffee, then banana. The final suitability maps generated showed that the suitable areas for production of the four different commodities changed greatly when the hazard component is included. Mitigation activities can be applied to increase the suitable areas for crop production. Adaptation through growing crops more resilient to climate change effects can also be undertaken.
Application of land management information to improve the tracking of changes...Richard Thackway
Most changes over time in the extent and condition of native vegetation types can be accounted by changes in Land use and land management practices (LMP). Obvious changes and trends in the structure, composition and function of native vegetation can be detected using remote sensing. While environmental models are helpful they must access site data on the effects that LMP have on essential environmental variables. More subtle changes in native vegetation extent and condition must be directly measured using ground-based observations of the interactions to attribute cause and effect to natural processes and LMP. Ideally we need an information system which informs the survey, classification and mapping and modelling of LMP at various scales

Assessing and reporting resilience of native vegetation using metrics of stru...Richard Thackway
The effects of contemporary and previous land management practices are reflected in the present-day condition of native vegetation. In order to properly manage land for productive use or to restore it to its 'natural' condition, it is important to know the changes that have taken place to the use of the land, and the cumulative effect of those changes. Assessing and reporting the resilience of native vegetation using metrics of structure, composition and function is discussed. The system, VAST-2, has been developed in the Australian context, where land management was relatively unchanged for some tens of thousands of years prior to European settlers who arrived some hundred years hence. This reference state provides a structure in which to compile, interpret and sequence data gathered in the past about changes in management practices and the effects of these practices on the condition of native plant communities. Early settlers and subsequent land managers have modified and fragmented the native vegetation thereby transforming many landscapes.
This study evaluated the effects of different cover crop treatments on soil health and pumpkin yields in no-till systems in Kansas. Soil samples were taken over three years to measure aggregation and microbial biomass. Cover crops generally improved soil aggregation compared to conventional tillage after 2-3 years. Pumpkin yields were not reduced in 4 of 5 site-years when planting directly into rolled cover crops compared to tilled plots. The results indicate cover crops can benefit soil health in pumpkin production without lowering yields when managed appropriately.

This document provides information on Farmer Field Schools and Agro-Ecosystem Analysis (AESA). It discusses how AESA is conducted through weekly field observations and analysis by farmers in small groups to monitor plant health, pests, diseases, and other agro-ecosystem factors. The farmers then discuss their findings and make consensus-based decisions on integrated pest management practices. The methodology involves collecting data, drawing diagrams, group discussions, and presentations to develop observation, analysis, critical thinking and decision-making skills for sustainable crop management. The goal of AESA is to replace the outdated economic threshold level approach with a more holistic analysis of the agro-ecosystem.
- There have been changes in water yield (Q) and evapotranspiration (ET) in unmanaged forests of the southern Appalachians over time.
- Q increased from 1938-1970s in low elevation watersheds but decreased 22% from the 1970s-2013, while ET initially declined but increased markedly since the 1980s.
- Changes in precipitation (P) and potential evapotranspiration (PET) explain some changes in Q and ET, but shifts in forest species composition and structure also contributed, potentially decreasing Q by up to 18% in some years.

This project aims to (1) evaluate transport processes of sediment, nutrients, and bacteria using hydrologic and water quality models, (2) evaluate the sensitivity of conservation practices on downstream water quality and quantity under climate change, and (3) develop extension programs to educate watershed stakeholders. The project uses models to simulate streamflow, crop yields, and water tables, which are calibrated and validated against field data from the Big Sunflower River watershed in Mississippi. Preliminary results show the impacts of crop rotations and tillage practices on groundwater and the potential effects of climate change on yields.
VAST: A Framework for Assessing the Transformation of Native Vegetation Richard Thackway
The VAST framework was developed for assessing and reporting on the degree of modification of plant communities modified by land management regimes and production systems. Modification is assessed using criteria and indicators of ecological function, structure and composition. Depending of the need VAST can operate at spatial and temporal scales. The framework is outlined showing how the degradation and restoration of forest/vegetation types relates to deliberate and unintentional land management decisions. A case study of the Cumberland State Forest, Pennant Hills, New South Wales is presented. Users of the framework consider four key issues; 1) Must differentiate severe natural disturbance events from impacts of land management regimes; 2) Must define reference state using the same indicators of ecological function, structure and composition; 3) Must understand stable condition states and multiple benefits (ecosystem services); and 4) Must understand interactions between patterns of rainfall and land management regimes.

This document summarizes a master's thesis that investigated wild bee community structure and diversity across different habitat types, including a permaculture farm, to evaluate the ecological performance of permaculture systems. The study sampled bee communities in 10 sites across 4 habitats in northern France. It found that bee diversity was highest in a site within the permaculture farm. When habitats were classified on a biodiversity gradient, bee diversity was generally higher within the permaculture farm, suggesting permaculture promotes bee diversity better than other habitats. The study also evaluated the economic importance of insect pollinators for several crops. It concluded that permaculture systems like the farm studied seem to be a relevant alternative for ecologically intensifying agricultural landscapes by
This document summarizes a study on the effect of skip-row planting configurations on cotton yield, biomass, and soil moisture in South Carolina. It finds that skip-row planting tended to conserve soil water, produce larger individual plants but reduce biomass per unit area. Specifically, single skip-row planting produced similar biomass and yield as solid planting while reducing seed costs, increasing income compared to solid planting. However, double and alternate skip-row planting reduced income compared to solid planting.
Genotype by environment interactions and effects on growth and yield of cowpe...Premier Publishers
Cowpea is widely grown in the humid tropics as staple and is largely affected by genotype by environment interaction (GEI). Data obtained from field trials were subjected to genotype (G) by environment (E) interaction (GEI Biplot) analysis and was applied to examine the nature and magnitude of GEI and quantify their effects on cowpea performance in seven experimental trials in a rainforest and derived savanna agroecologies of south-west Nigeria. Results showed that genotype x environment interactions effects were significant on cowpea growth and yield characters. The differential performance of cowpea varieties as early- and late- rainy season crops at both locations were attributable to variability in the soil, weather and biotic factors of the test environments. Determination of winning genotype(s) and yield ranking across environments showed that cowpea varieties depicted differential performance for the test environments and hence the interaction was crossover type. Varieties IT97K-568-18, IT97K-568-18 and Oloyin Brown are high yielding while IT96D-610 and IT98K-205-8 are poor. Oloyin Brown and IT98K-573-2-1 won in Akure 1, 2, 3 and 4 and Ado 1 while IT97K-568-18 won in Ado 2 and Akure 5. IT96D-610 and IT98K-205-8 did not win in any environment. The best performing varieties, Oloyin Brown, IT97K-568-18 and IT98K-573-2-1 combined both high yield and stable performance across test environments and were characterized as ideal genotypes while most unstable variety, IT96D-610, performed poorly in test environments. It is concluded that Ado-Ekiti was best for the late rainy while Akure location was best for early rainy season cropping.

The project uses models to simulate streamflow, crop yields, and water tables, which are calibrated and validated against field data from the Big Sunflower River watershed in Mississippi. Preliminary results show the impacts of crop rotations and tillage practices on groundwater and the potential effects of climate change on yields.
VAST: A Framework for Assessing the Transformation of Native Vegetation Richard Thackway
The VAST framework was developed for assessing and reporting on the degree of modification of plant communities modified by land management regimes and production systems. Modification is assessed using criteria and indicators of ecological function, structure and composition. Depending of the need VAST can operate at spatial and temporal scales. The framework is outlined showing how the degradation and restoration of forest/vegetation types relates to deliberate and unintentional land management decisions. A case study of the Cumberland State Forest, Pennant Hills, New South Wales is presented. Users of the framework consider four key issues; 1) Must differentiate severe natural disturbance events from impacts of land management regimes; 2) Must define reference state using the same indicators of ecological function, structure and composition; 3) Must understand stable condition states and multiple benefits (ecosystem services); and 4) Must understand interactions between patterns of rainfall and land management regimes.

This document summarizes a master's thesis that investigated wild bee community structure and diversity across different habitat types, including a permaculture farm, to evaluate the ecological performance of permaculture systems. The study sampled bee communities in 10 sites across 4 habitats in northern France. It found that bee diversity was highest in a site within the permaculture farm. When habitats were classified on a biodiversity gradient, bee diversity was generally higher within the permaculture farm, suggesting permaculture promotes bee diversity better than other habitats. The study also evaluated the economic importance of insect pollinators for several crops. It concluded that permaculture systems like the farm studied seem to be a relevant alternative for ecologically intensifying agricultural landscapes by
This document summarizes a study on the effect of skip-row planting configurations on cotton yield, biomass, and soil moisture in South Carolina. It finds that skip-row planting tended to conserve soil water, produce larger individual plants but reduce biomass per unit area. Specifically, single skip-row planting produced similar biomass and yield as solid planting while reducing seed costs, increasing income compared to solid planting. However, double and alternate skip-row planting reduced income compared to solid planting.
Genotype by environment interactions and effects on growth and yield of cowpe...Premier Publishers
Cowpea is widely grown in the humid tropics as staple and is largely affected by genotype by environment interaction (GEI). Data obtained from field trials were subjected to genotype (G) by environment (E) interaction (GEI Biplot) analysis and was applied to examine the nature and magnitude of GEI and quantify their effects on cowpea performance in seven experimental trials in a rainforest and derived savanna agroecologies of south-west Nigeria. Results showed that genotype x environment interactions effects were significant on cowpea growth and yield characters. The differential performance of cowpea varieties as early- and late- rainy season crops at both locations were attributable to variability in the soil, weather and biotic factors of the test environments. Determination of winning genotype(s) and yield ranking across environments showed that cowpea varieties depicted differential performance for the test environments and hence the interaction was crossover type. Varieties IT97K-568-18, IT97K-568-18 and Oloyin Brown are high yielding while IT96D-610 and IT98K-205-8 are poor. Oloyin Brown and IT98K-573-2-1 won in Akure 1, 2, 3 and 4 and Ado 1 while IT97K-568-18 won in Ado 2 and Akure 5. IT96D-610 and IT98K-205-8 did not win in any environment. The best performing varieties, Oloyin Brown, IT97K-568-18 and IT98K-573-2-1 combined both high yield and stable performance across test environments and were characterized as ideal genotypes while most unstable variety, IT96D-610, performed poorly in test environments. It is concluded that Ado-Ekiti was best for the late rainy while Akure location was best for early rainy season cropping.

The program held two regional workshops that covered issues like water and soil sustainability, wildlife habitat, and conservation systems. Agents reported increased knowledge after the workshops. Feedback was positive, though challenges include the broad scope of agriculture and competing demands on agents' time. The program seeks to improve consistent messaging and ensure its long-term sustainability.
Agriculture, Ecology and a New Path ForwardSteve Oberle
The document discusses agroecology and the need for more sustainable agricultural systems. It defines agroecology as the study of interactions between the natural environment and human agricultural activities. It notes that while agricultural productivity has increased since the 1950s due to external inputs, this has degraded natural resources like land and water. The document argues that agroecology provides an ecological basis for more sustainable farming and assessing agriculture's role in various environmental and social issues. It concludes that a transition is needed toward more diverse and management-intensive farming systems that rely less on specialized operations and more on on-farm resources.

A 20-year study compared surface runoff quantity and quality from native prairie and cropped livestock grazing systems in central Oklahoma. Runoff, sediment, and nutrient losses were consistently lower from the native prairie (watersheds 1-4) compared to the maximally disturbed watersheds (6 and 8) that were conventionally tilled. The native prairie had increased infiltration and canopy interception, which reduced runoff and erosion. Lower fertilizer inputs to the native prairie also decreased nutrient losses. The long-term data collection contributed to national research networks on agricultural impacts to water quality.

A farmer wrote a letter to the editor arguing that large-scale concentrated animal feeding operations (CAFOs) are unsustainable and threaten local water resources. The farmer claims that using livestock manure to enhance soils and promote plant health is a sustainable agricultural practice, but that using land as a means of livestock waste disposal undermines sustainable ecology and threatens downstream groundwater and surface water.
This document provides an overview of groundwater basics and factors influencing groundwater quality and quantity in Taylor County, Wisconsin. It discusses watersheds, wellhead protection, approaches to addressing groundwater issues from both a bottom-up and top-down perspective, and Taylor County's drinking water education and testing program. Key points include that Taylor County has taken a bottom-up approach focusing on local groundwater data, and that top-down factors like geology, land use, and precipitation influence groundwater test results showing hazards like arsenic, iron, and manganese in some wells.
A Case for Agricultural Systems ResearchSteve Oberle
This article discusses the importance of agricultural systems research in understanding the complex relationships between human, socioeconomic, and natural environmental systems. It argues that developing effective farm management strategies requires analyzing both farm manager goals and limitations as well as the fundamental components of farming systems and their interactions. The article defines key systems concepts and uses a systems approach to identify and discuss the typical components and general goals of agricultural systems.
Farming Systems Options for U.S. Agriculture- An Agroecological PerspectiveSteve Oberle
Farming systems research and extension (FSRE) and other systems-oriented approaches are essential for addressing complex agricultural problems and developing sustainable farming systems. Conventional reductionist agricultural research has led to productive systems but also substantial environmental and human costs. FSRE is a farmer-based approach originally used in low-income countries to involve stakeholders in problem diagnosis, technology adaptation and evaluation. Agroecology provides an ecological basis for characterizing relations between agriculture and natural resources to develop sustainable systems. Systems approaches allow understanding of whole-farm impacts and identifying critical research needs.
A Framework for Regional Agroecosystems Characterization Using the National R...Steve Oberle
An agroecological framework uses spatial data from the National Resources Inventory to characterize regional agroecosystems in the Midwest. Maps show the extent natural resources have been modified to support agriculture, with over 70% of land used for crops and pasture and less than 10% remaining as natural vegetation. Over 35% of some areas have installed subsurface or surface drainage systems, decreasing wetlands and potentially impacting water quality. Irrigation has diverted water from natural ecosystems and may increase agrichemical leaching. Excess erosion in parts of the region could threaten long-term productivity despite implemented conservation practices. Examining these agroecosystem components may help sustain agriculture and resources in the region.
