Irrigation

This study by Geospatial World attempts to collect and analyse data concerning the catchment characteristics that affect direct runoff such as soil type, land cover and rainfall for the catchment of Lokapavani river in Karnataka using remote sensing and GIS techniques. An attempt has been made to determine the weighted average Curve Number (CN) for different land use, land cover and soil types in Lokapavani catchment in order to estimate the runoff.

This paper by Greenpeace on ecological farming illustrates proven, modern farming approaches that help cope with drought. It elaborates on the drought-resistant crop varieties and calls for policy makers to increase funds for research on the system. 

Human-induced climate change is resulting in less and more erratic rainfall, especially in regions where food security is very low. The poor in rural and dry areas will suffer the most and will require cheap and accessible strategies to adapt to erratic weather. This adaptation will need to take into account not only less water and droughts, but also the increased chance of extreme events like floods. 

Biodiversity and a healthy soil are central to ecological approaches to making farming more drought-resistant and more resilient to extreme events. Practices that make soils better able to hold soil moisture and reduce erosion and that increase biodiversity in the system help in making farm production and income more resilient and stable.

India’s arteries are choking. Her rivers, the lifeline of hundreds of millions, are over-taxed, polluted and encroached. They are being mined, dammed and emptied of water. Save for the four monsoon months, most rivers are streams of drains, depending on how many cities they pass through. This year people gaped in awe at the River Yamuna (I am sure they were over-awed by other rivers elsewhere too) as for the first time since 1978 looked like a river and not a drain.

This study by IWMI maps the household water poverty in a typical remote village of the northeast, understands the causes for such a scenario and reflects on the past efforts. Local water resource-based multiple-use water systems that provide water supply both for household and livestock needs and for small high-value agriculture are understood. 

The per capita and per hectare availability of water in India is highest in this region but the societal (both productive and consumptive) water use is less than five per cent of the existing potential. The unutilised and excessive water supplies during the rainy season create a mayhem of devastations almost every year with ravaging floods, landslides, soil erosion and other infrastructural failures and miseries and unrest in large parts.

In this article published in Commodity Vision, the author presents the concept of the establishment of a 'futures market in water availability' in the context of the risk of water availability that Indian agriculture has been facing in the recent years.

With South Asian agriculture being dependent on the timely occurrence of the monsoons, any deviation from the scheduled arrival of the monsoon causes problems not only for the farmers, but also produces a threat to the food security of the region. However, the author argues that, there is no market in South Asia where users and investors exposed to water availability risk can effectively hedge against such a risk.

This paper by the World Resources Institute outlines potential water-related risks facing the mining industry and highlights important gaps in water-related disclosure. The purpose is to provide information, questions, and tools to help the financial community better evaluate water-related risks facing mining companies.

This working paper by the University of Bonn attempts to give a spatial and temporal overview of water management in India. It traces how people and the successive regimes made choices across space and time from a wide range of water control and distribution technologies. The paper divides the water management in India into four periods –

• the traditional system of water management before colonial times;
• response from the colonial rulers to manage the complex socio-ecological system;
• large scale surface water development after independence; and
• finally, the small-scale community and market-led revolution.

This work on water footprint assessments represents a pioneering effort on documenting the water consumption in Jain Irrigation Systems Limited’s (JISL) production of dehydrated onions and of micro-irrigation systems. It also assesses the sustainability of this water consumption and formulate response strategies. 

This report on farmers’ experiences on System of Rice Intensification (SRI) in India by ICRISAT and WWF is an effort to compile the experiences of those farmers who pioneered the SRI method in various regions. They experimented in their own way, articulating their point of view on the method. 

The SRI is a national phenomenon in India and rice-cultivating farmers, particularly those who have less than one hectare of land, have experimented, refined, adopted and are promoting SRI. It is their hard work and trust that has spread this unknown method into all rice-growing states. Out of 564 rice-growing districts in India, SRI is being practiced by the farmers in about 216 districts.

I would like to share about Mr. Veerabhadrappa and his wife Ms. Sumangalamma who are doing number of experiments in agriculture in 80 acres of their land located in Bijekere village, Molakalmur Taluk, Chitradurga, district of Karnataka state. The farm is located 120 kms from Anantapur and 65 kms from Bellary, on the Bellary – Bangalore High way and just 30 kms from our field office at Rayadurg.
