Ecological Restoration Of Common Pastures Through A Community Led Multi-Stakeholder Partnership, Giresh Mohan, Sarvashish Roy

IGC Proceedings (1977-2023)

Kalyanpura watershed, spread over 5,175 ha area with 16 villages, is situated in the drought prone district of Bhilwara in Rajasthan. Prior to project initiation, only 27% of the area in Kalyanpura was under agriculture and the balance was mainly accounted for by village commons used for livestock grazing and fuel wood collection. Although the area receives an average annual rainfall of 700 mm, the undulating landscape, shallow soil cover and the absence of any soil moisture conservation resulted in high runoff and degraded commons. Recurring droughts and absence of irrigation facilities made farm based livelihood vulnerable to seasonality, especially …

A Proposal For Improving Pastures In Subsistence Farming Systems On The East India Plateau, Shivendra Kumar, Ashok Kumar, Peter Stuart Cornish

IGC Proceedings (1977-2023)

The East India Plateau (EIP) experiences deep poverty despite high rainfall (> 1200 mm). Livelihoods, once derived from Sal (Shorea robusta) forest, now depend on agriculture. Subsistence farmers practice monoculture rice-fallow on small, fragmented landholdings (total < 1 ha). Rice in the undulating landscape was traditionally grown in lowland drainage lines (Fig. 1) but population pressure has forced it onto adjacent terraced slopes (medium-uplands) that now comprise > 80% of the rice area (> 50% of land area). Rice is protected from grazing, but the watershed is otherwise grazed as common land with no pasture management. Grazed uplands are often degraded and unproductive, receiving no inputs. Livestock are limited to large animals providing draft power (males) and manure (fuel, compost), and goats for emergency finance.

Rainfall is not the primary …

IGC Proceedings (1977-2023)

Mixed farming pasture-crop rotation systems in southern Australia have traditionally relied on subterranean clover and annual medics. Concern over the long-term persistence of these species was raised in the 1980‟s with the cessation of manufacture of suction harvesters required for seed production. Subsequently, their adaptation has been tested due to climate change. More frequent droughts, particularly the millennium drought (2002-2009), increased incidence of false breaks and dry spring conditions causing decline or complete loss of seedbank reserves and failure of new sowings. A concerted effort developing new legume species for Australian farming systems, led by Western Australia, resulted in domestication …

Cover Crops Alternatives For Sustainable Agriculture Systems In Uruguay, Walter Ayala, José A. Terra, Ethel Barrios, Ignacio Macedo

IGC Proceedings (1977-2023)

In Uruguay, the increase of cropland area during the last decade was based on rotation systems intensification and soybean expansion, achieving 1.321.000 ha (Souto, 2014). Diaz (2007) demonstrated the value of the ley-farming systems where the integration of livestock and crop production achieved benefits on sustainability. Despite the advantages of crop-pasture rotation systems (García Prechac et al., 2004), grain market prices and food demand resulted in pasture phase losses in rotation with crops. Recently, Livestock Agriculture and Fisheries Ministry implemented a national soil conservation plan, that regulates cropping rotation systems based on soil erosion estimations and other key soil …

Application Of Payment For Ecosystem Services In China’S Rangeland Conservation: A Social-Ecological System Resilience Perspective, Wenjun Li, Yanbo Li

IGC Proceedings (1977-2023)

Payment for ecosystem services (PES) has been adopted by the Chinese government over the past decade as a mechanism to combat regional-scale rangeland degradation. We analyzed some fundamental problems associated with PES application in rangeland management from the perspective of social-ecological system (SES) resilience by using as a case study he PES project of “retire livestock to restore rangeland” in Inner Mongolia. The study findings demonstrated that PES project resulted in obvious negative impacts on local pastoralists’ livelihood and society networks without achieving any substantial rangeland restoration. Such failures are rooted in that PES strategy in which the logic of …

Variance Heterogeneity Genome-Wide Mapping For Cadmium In Bread Wheat Reveals Novel Genomic Loci And Epistatic Interactions, Waseem Hussain, Malachy T. Campbell, Diego Jarquin, Harkamal Walia, Gota Morota

Department of Agronomy and Horticulture: Faculty Publications

Genome-wide association mapping identifies quantitative trait loci (QTL) that influence the mean differences between the marker genotypes for a given trait. While most loci influence the mean value of a trait, certain loci, known as variance heterogeneity QTL (vQTL) determine the variability of the trait instead of the mean trait value (mQTL). In the present study, we performed a variance heterogeneity genome-wide association study (vGWAS) for grain cadmium (Cd) concentration in bread wheat. We used double generalized linear model and hierarchical generalized linear model to identify vQTL associated with grain Cd. We identified novel vQTL regions on chromosomes 2A and …

Forage is the main product of rangelands. According to the heterogeneity of range forages in terms of economic and lacking organized market for transaction, despite of imagine of ecological economists, it's a public good. So, determining its economic value as one of the main important nonmonetary functions of rangelands ecosystems can help managers to …

Operator Bias And The Effect Of Training On Visual Assessments Of Pasture Yield For Forage Budgets In Northern Australian Savanna, Nicole B. Spiegel, Peter O'Reagin, Angela Anderson, Megan R. Willis

IGC Proceedings (1977-2023)

Sustainable management of Australia’s extensive northern grazing lands is challenging given its highly variable interannual rainfall and pasture production. Accordingly, a key management recommendation is to adjust stocking rates to match forage supply (O’Reagain et al., 2014). ‘Stocktake’ is a forage budgeting system (Aisthorpe et al., 2004) widely used and promoted to assist graziers make short-term (< 1 year) adjustments of stocking rate. Budgets are typically calculated at the start of the dry season, to ensure sufficient forage for stock and ground cover levels until the first rains some six to nine months later. The software application ‘Future Beef Stocktake Plus’ has also been developed for use on smart devices (http://www.stocktakeplus.com.au/).

A key requirement for forage budgets is an accurate estimate of pasture mass. This is typically done visually with the aid of photo standards of pasture mass, providing a simple, efficient and non-destructive approach. Other key variables of forage budgeting include …

Economic Review Of Pasture Development Options For North Australian Beef Enterprises, Neil D. Macleod, Dianne Mayberry, Lindsay Bell, Ian Watson

IGC Proceedings (1977-2023)

Beef cattle grazing (~14 million head) native pastures is the dominant economic use of northern grazing lands (2.3 million km2). Few enterprises make positive economic returns in most years or achieve the necessary productivity gains (~2% per annum) to offset an ongoing cost-price squeeze (McCosker et al., 2010). A significant contributor to poor performance is low reproductive performance, management of first calving heifers, calf growth and weaning rates and liveweight gain - linked to nutrition and the low quality of pastures. Pasture development technologies (Gramshaw and Walker, 1988) are available but uptake has been poor. Three pasture development options …
