MIRZA, Sept 28

Ongole, July 27: Aqua culture and salt industries have turned soil saline in many parts of Prakasam district making large chunks of land unfit for cultivation. Salt cultivation is on in 7,867 acres in four mandals of the district and in the last one decade, aquaculture is also on the rise in nine mandals.

Studying the data spread over 23 years (1981-2003), the Food and Agriculture Organisation has concluded that 24 per cent of the global land area has degraded. This is over and above the extent of land that had already degraded. The situation has only worsened since 1991 when the previous assessment was made. According to the FAO, in India about 592,000 square kilometres of land has deteriorated

Visakhapatnam, July 16: The state secretary of CPI, Dr K. Narayana, said that their party was opposing the state government's proposal to develop Coastal Corridor between Itchapuram in Srikakulam district and Tada in Nellore district and launched a pro-CPI test campaign in this regard to create awareness among those living in the coastal areas about the ill effects of the proposal.

The age-old practice of turning the soil before planting a new crop is a leading cause of farmland degradation. Many farmers are thus looking to make plowing a thing of the past.

In the hill areas, the traditional systems of dependence on forest products like fuel for their households and fodder for their livestock has an important bearing on the status of Himalayan watersheds. The population of livestock is therefore also significant. The fuel and fodder requirements of the hill people are important routine activities for which women/children spend long hours of their day-to-day life.

Despite various initiatives taken by the Centre, including soil and water management activities, 32.75 per cent of the country's geographical land is still affected by various forms of land degradation or desertification.

In semi arid areas such as the Sahelian zone of Africa, many oils have become severely degraded. One extreme form is the bare and crusted soil, which is virtually productively "dead". In Burkina Faso, farmers have responded by applying mulch to attract termites that then help to rehabilitate the soil. A research project shows the importance of termites in breaking up hardened soil and increasing water infiltration. The land became productive enough to farm within months.

India carries a huge livestock population. Small ruminants, namely, goats and sheep, play a vital role in securing the livelihood of small and marginal farmers and landless labourers. Such animals should not be blamed for the ecological degradation, soil erosion and desertification caused by human activities.

The inter and intra-year fluctuations in agriculture production will continue as long as agriculture depends on weather. The effect of weather on agriculture is related to location specific which directly link with the variability in local climates rather than in global climate patterns. Many scientists hold the position that agricultural shifts are likely due to climate change.
