Soil And Water

Semi-arid lands were at times during the last 20000 years more humid and at other times more arid than at present, with important consequences for the soil and water resources of the present day. These lands were the scene of the beginnings of pastoralism, the cultivation of cereals, and urban living between 10 000 and 5000 years ago. The environment has always been attractive to man but it is liable to deteriorate towards desert with long-lasting consequences. Development possibilities diversify according to environmental conditions which vary from place to place and also according to the economic and other characteristics of the States in which these lands are situated. The States can be regarded as falling into four categories: there are on the one hand wealthy countries - either industrialized or rich in minerals; on the other hand there are poor countries - some with land outside the arid zone as yet not fully developed, others with no land of this kind. In response to the differences in economic opportunity, migratory movements are taking place, notably from the impoverished semi-arid regions to the towns, particularly those in the petroleum-producing states.

This article represents the results of multi-annual researches of desertification processes in droughty part of Europe - Russian Caspian Basin. Authors consider desertification as unification which leads to degradation of all components of arid ecosystems. It has been determined, that ecological-dynamic series of vegetational communities have the largest indicative value on quaternary terraces of Caspian Basin. They allow to trace the degradation sequence, to allocate the evaluation criteria and stages of desertification. Modern region vegetation is a result of cattle pasture and water management. It has been established that the vegetation of Late Khvalynian terrace on loamy soils is the most resistant to processes of degradation. The most vulnerable is young New Caspian. Cartographic materials confirm convertibility of desertification processes in semi-arid zone of European continent in response to natural-anthropogenic factors.

Introduction: The São Francisco River Basin Committee (CBHSF) was set up by presidential decree in 2001 with the aim of achieving decentralized and participatory management of its water. The São Francisco River flows overland for 2700 km from its source in the Serra da Canastra (MG) to its mouth between Sergipe (SE) and Alagoas (AL). The river passes through the states of Bahia (BA), Pernambuco (PE), Goiás (GO) and the Federal District (DF). Central to the discussion in this research on the transposition of the São Francisco River is question of conflict concerning water management in the São Francisco River Basin Committee, making a nonsense of its power to function, contrary to the project, and the Federal Government which initiated the work and approved the budget. Hence, this study aims to analyze water management in the São Francisco river basin from the initiation of the CBHSF in order to understand how approval of the project and implementation of the work ran against the statutory representation of the committee. Methodology and Development: Having a qualitative approach, the study will be divided between theoretical research based on authors who study the topic of water and its transformation into a water resource and the major landowners of the north-east semi-arid zone in the context of transposition; the dynamics and politics of the river basin; as well as the role of the river basin committees in the process of decentralizing Brazilian water management, specifically concerning the São Francisco River and its state and interstate committees. Documentary research will take into account National Water Resources Law 9.433/1997; state water policies; documentary archives of the river basin committees (state and interstate), as well as the agencies participating in the integration project, such as the National Water Agency (ANA), the Integration Ministry (MI), and the Environment Ministry (MMA). Further data will be obtained using the transcripts of semi-structured interviews with presidents of the river basin committees as well as visiting transposition works and attending CBHSF meetings. Final thoughts: The transposition of the São Francisco River demonstrates how the legacy of Brazilian governmental centralization policies holds back the participatory process of the river basin committees, encroaching on their legal and institutional positions as regards water in the north-east semi-arid zone amid the persistence of drought.

Extract Information

The present study was carried out in three districts viz; Rewari, Sirsa and Hisar of Haryana state. A survey of 60 sampled farms was conducted to extract information pertaining to various expenses incurred in cultivation of castor and output attained as well as to ascertain the perception of farmers for various problems encountered in production and marketing of castor seed. The descriptive analysis was employed to draw valid inferences from the study. The results revealed that net profit accrued from cultivation of castor seed was ₹ 46331 ha -1 in the study area. The value of B: C ratio of castor cultivation was more than one and also higher as compared to prevalent cropping systems indicated that cultivation of castor seed is economical viable entity. However, production constraints like retention of F2 seed in the field over year, grain scattering, shortage of irrigation water, frost effect on crop yield and marketing constraints like absence of MSP, higher transportation cost sale of castor seed in distant markets, frequent fluctuation in market price, non-availability of processing units were observed.
