    How long does it take to pay back rangeland improvement investments? A case study from Erzurum Province in Turkey
    (Csiro Publishing, 2014) Kara, Abdurrahman; Kadioglu, Sibel; Dumlu, S. Emre; Aksakal, Erdal; Ozgoz, M. Merve; Uzun, Mustafa; Cakal, Serafettin
    The aim of the study was to estimate the payback period of rangeland improvement investments made under the coordination of the Eastern Anatolia Agricultural Research Institute (EAARI) in the Eastern Anatolia region, Turkey. Farm data were collected from randomly selected rangeland-dependent dairy cattle farms through face-to-face interviews, which resulted in 99 completed questionnaires. Additionally, the data for rangeland improvement studies were obtained from the EAARI. The villages of study were selected from those for which rangeland condition had been determined previously. The data collected by structured questionnaires were for the 2004-05 production year. The farms were studied under three farm size groups of 0-12, 12.1-25 and 25+ ha. Gross margins were calculated for each studied farm. In the analysis of the data, stepwise regression, multiple linear regression and descriptive statistical methods were used. Of the 17 variables considered, only four variables entered to the log-linear livestock gross margin model. These were the type of building used by livestock in winter, cattle and sheep numbers and rangeland condition. Using estimates of the average values of the unit costs of rangeland improvement and additional incomes due to the improvements, it was estimated that on average each Turkish lira invested in rangeland improvement studies could be amortised in three grazing seasons.

    Twofold excessive utilization rate yields high financial equivalent but seriously threatens public rangelands in Turkey
    (Gültekin Özdemir, 2019) Kara, Abdurrahman; Dumlu, Emre Sureyya; Uzun, Mustafa; Çakal, Şerafettin
    The aim of this study was to estimate the utilization rate and financial equivalent of the utilized rangeland forage to quantify the extent of grazing pressure on the semiarid Turkish rangelands, and to attract the public attention to the importance of rangelands in national economy. The study was conducted in Erzurum province of Turkey. In permanent 12 representative sites in each of village rangelands, cages of 1 m height and 1 m × 1 m floor area, were placed and forage under cages was clipped to the ground at the end of the grazing seasons in 2007 and 2008. Simultaneously, the forage outside the cages was sampled with random quadrats. Financial equivalent of the utilized rangeland forage was estimated using surrogate market valuation method. In data analysis were employed descriptive statistical methods and one-way ANOVA test. According to the results, the average rangeland dry forage yield was 1012 kg.ha–1 and rangeland utilization rate was 69 per cent, roughly two-fold higher than suggested rates. Under the prevailing conditions, the financial equivalent of the utilized rangeland forage is about 526 TRY or 92 USD per hectare. It was concluded that utilization rate or grazing period should be deflated by 50% for sustainable resource use by allowing rangeland plants to regenerate.
