In the north China Plain and Loess Plateau, for example, many efforts have been paid to increasing water-use efficiency (WUE, yield per unit evapotranspiration) with an acceptable crop yield (Zhang et al., 2013a).

The average rate of increase of SOC (g kg− 1year− 1) in 0–20 cm depth under NT systems is 0.60–3.74, 0.14–4.15, 0.50–5.94, and 8.81–17.95 for the Northeast, North, Northwest, and paddy fields of Southern China, respectively. It is especially true for an agrarian economy like Indiaâs where more than half the population is dependent on agriculture. Residue management in zero till systems (surface retention) improved soil health (Sharma and Prasad, 2008), reduced GHG emission equivalent nearly 13 tonnes/ha (Mandal et al., 2004) and lowered leaf CT at grain filling stage mitigating terminal heat stress in wheat (Gupta et al., 2010; Jat et al., 2011). We use water every day of our lives. Since the 1970s, large efforts have been made on research and demonstration of conservation agriculture in China, where it has been applied in 6.4 × 106 ha by 2012 with a projected increase to 11 × 106 ha by 2015 (GOV, 2009). While there are some plants that can live in water or air, most plants need to be rooted to the ground. Practicing CA entails a number of changes in the way that smallholder agriculture is conducted, perceived, and planned. This aspect of conservation is another key area in which CEA differentiates itself from conventional farming. The average global transfer o⦠Anyhow, the supply of the water is almost constant. Moreover, the environmental cost of applying pesticides for weed, insect-pest and disease control in CA fields may be much higher and many a times unaccountable with severe ecological hazards and consequences. Therefore, Water Conservation means an act of using water efficiently to prevent wastage. In addition, water conservation saves money, minimizes the effects of water shortage and ensures that future generations have an adequate water supply. This is the sole reason why finding traces or signs of water is an important criterion of planetary exploration. Table 3.2. It is important because, currently, only about 10 percent of Earthâs waste water is disposed of appropriately, discloses About.com. Conservation agriculture (CA) is a climate change adaptation measure being promoted for small-scale farmers in Zambia. As a result in North Cameroon, net returns to land were calculated to be on average €76 荤 ha−1 more with cotton produced under CA than with cotton produced conventionally, which yielded an average of €225 荤 ha−1 (Raunet and Naudin 2006). (2016) reported that conventional tillage may have significantly higher surface area and volume of cracks than soil under NT management. In view of crop residue significance in CA the nutrient management research assumes vital role for improving soil and crop productivity along with environmental quality. At the same time, energy demands will also get bigger, which will translate into more water consumption in the energy sector. (2004) demonstrated straw mulching significantly increased the harvesting of rainwater and yield. An illustration of some of the factors that describe a farmer who can potentially rip benefits by applying conservation agriculture practices. It counters the concept of soil tillage/ ploughing prior to planting, additionally marking it as being responsible for destruction of soil organic matter, a crucial element for the stabilisation of soil structure. Surveys of farmers' fields adopting no-till wheat systems in India (Malik et al., 2004) and Pakistan (Khan and Hashmi 2004) showed that farmers who have adopted no-till planting of wheat after rice had definite economic and social benefits accruing from this technology.
