- Environmentalists and conservationists have often advocated communal control of natural resources as a way to ensure its judicious and sustainable use (Colchester, 1994; Kothari, 2011). Since the early 1980s, economists, sociologists and cultural anthropologists have documented cases of sustainable natural resource management by local communities (Acheson, 1988; Ostrom, 1990; Berkes, 1986). This was followed by sophisticated theoretical models that showed that ‘commons’ — resources that are jointly managed — often follow trajectories that are not ‘tragic’ (Sethi and Somanathan, 1996; Chichilnisky, 1994). Once Ostrom and others had demolished the infallibility of the Tragedy of the Commons, policymakers around the world started viewing communal control as a panacea to solve all kinds of natural resource problems.

- This study was aimed to optimize glucose level at different stages of buffalo in vitro embryo production procedure. Three glucose levels (1.5, 5.6 and 10 mm) along with a control (0 mm) were used at three phases of in vitro fertilisation (IVF) procedure viz. in vitro maturation (IVM), in vitro culture (IVC-I) (12-72 hpi) and IVC-II (72 hpi to 7 dpi). Maturation rate of oocytes was found different under different glucose concentrations, and significantly more number of oocytes reached to MII under 5.6 mm glucose. The glucose levels at each phase (IVM, IVC-I and IVC-II) individually had significant effect on blastocyst rate, and the level used at one phase had significant effect on the outcome of next phase. Complete withdrawal of glucose from any of these stages irrespective of concentrations used at subsequent stage/s resulted in significantly lower number of blastocysts. However, the changing levels of glucose had differential effects during different phases of IVF steps. The most prominent effect of glucose level was observed during IVM. The presence of 5.6 mm glucose at all stages was most effective to yield highest blastocyst rate in buffalo IVF system.
