Ponds are considered to be self-contained, land lock ecosystem which is often teeming with rich vegetation and diverse organismal life. The pond water contains different organic and inorganic components. The experiment was carried out in laboratory, Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh through collection of pond water from Gouripur and Muktagacha under Mymensingh division for assessment of major ionic status and suitability parameters for irrigation and aquaculture usage in quantitative way. Around 30 samples were collected from different location. On the basis of HCO3 ion, all water samples except 3 samples were not suitable for irrigation because this anion exceeded the acceptable limit (1.5 meL-1). On the other hand, HCO3 ion was not treated as problematic in all samples except 2 samples for aquaculture usages. The concentrations of Ca, Mg, Na, K, PO4 and SO4 were far below the recommended limit. Considering aquaculture usage, Cl ion was considered as hazardous in all the pond water samples because this anion was above the legal limit (<0.003mgL-1). pH value of pond ranged from 7.02 to 7.87 indicating alkaline in nature and were not problematic for irrigation and aquaculture usage. Among the major ionic constituents, the remarkable significant correlations existed between Ca vs Mg, Ca vs K, Mg vs SO4, K vs Na, Na vs SO4. Res. Agric., Livest. Fish.6(2): 301-313, August 2019

Environmental protection has become a burning issue which plays a more and more important role in the world. The aim of this study is to give a picture of the constitutional regulation of environmental protection which is the highest legal source of a nation. Besides the Hungarian Fundamental Law, the German, Italian and Belgian constitutions were examined in the study. On one hand, we looked into how environment is regulated in the constitutions, as a right (right to environment) or a state task or objective (protect the environment). On the other hand, we analysed how related regulatory subjects appear in the constitutions, such as natural resources, future generations and sustainable development.

The productivity of forest natural resources is now decreasing and therefore rehabilitation efforts is urgently needed. Breeding of forest plant is the best solution to increase forest productivity in both quantity and quality. The biological reproduction can be conducted through seed production with fertilization. This research was aimed at determining the effect of fertilizing treatments on pod and seed production of different Glirisidia sepium provenances to find out the best provenance and best fertilizer dosage. Fertilization treatments showed a significant effect on the pod and seed production. On the other hand, the provenance and its interaction with fertilizing did not show any significant effects on the pod and seed production. The best performance was found on the fertilization treatment of 500 g resulting in the average production of 1,288 pods and 27,621 seeds/tree. Keywords: Fertilizing, Seed Production, Provenance, Glirisidia sepium

<p>Oil and gas are non-renewable types of natural resources. On the other hand, in the current era human dependence on oil and gas is very high. To meet Indonesia's national needs for natural resources, Article 33 of the Indonesian Constitution has mandated that "the earth, water and natural resources contained therein be controlled by the state for the greatest prosperity of the people." But in its development the distribution of welfare over natural resources, especially oil and gas, has not been able to be well distributed in Indonesia. The "Jakarta Sentris" concept is still the basis for distributing natural resources, especially oil and gas. This makes regions that are rich in natural resources not necessarily have prosperous people and not necessarily high-income areas. Therefore, legal reform is needed in the field of oil and gas management by regions in Indonesia.</p>

Ground water is one of the most useful water sources found in earth. The importance of the chemical analysis underlies the fact that the chemistry of ground water can directly be rated with the source of water, climate and geology of the region. Contamination of such water is responsible for creating health hazards. In this paper chemical analysis of the ground water has been carried out for Hinganghat in Wardha district. The water sample collected from different location in Hinganghat, Wardha (India). The ground water samples were analyzed for the following chemical parameters; pH, Electrical Conductivity (EC), Total Alkalinity (TA), Total Hardness (TH), Chloride, Nitrate, Sulphate, Dissolved Oxygen (DO) and Total Dissolved Solid (TDS). The results Obtained shown that it is free from anomalies and suitable for human and cattle consumption as well as irrigation purpose in Hinganghat, Wardha districts, Maharashtra, India.

Two countries in East Asia prompt students and visitors to think of them as likely to occupy, in the twenty-first century, a commanding world position. I have in mind, of course, that writers like Norman Macrae of the Economist and Herman Kahn of the Hudson Institute look at the Japanese system and project performance that will place Japan in the very forefront of world economies within the next twenty-five years—and this despite the relatively small size of the country and its almost total lack of natural resources. On the other hand, visitors like former Supreme Court Justice Douglas, Kenneth Scott Galbraith of Harvard, and many others have visited China and left it saying, in effect: “I have seen the future, and it works!”

Groundwater samples collected from 15 tube wells of six unions under Puthia upazila of Rajshahidistrict was evaluated their quality for irrigation usage in relation to soil properties and crop growth. Groundwater samples under test were slightly alkaline (pH = 7.10-7.34) in nature and were not problematic for crop production. As regards to TDS, allwater samples were classified as fresh water (TDS<1,000 mg L-1) in quality. EC and SAR values reflected that water samples were medium salinity (C2) and low alkalinity (S1) hazard classes expressed as C2S1. Regarding EC, all collected water samples could be safely used for crops growing on soils with moderate level of permeability and leaching. Groundwater samples were excellent in quality as per SAR and SSP. All water samples were free from RSC and belonged to suitable in category. All groundwater sampleswere hard in quality. The status ofHCO3,Fe, Mn, BO3, SO4, PO4 and Cl ions were recorded below the permissible limit for irrigation and these ions might not create hazardous impact on soil ecosystem. The relationships between chemical parameters of groundwater like EC, TDS, SAR, SSP, RSC and hardness (HT) were established. Significant correlations existed between EC-TDS, EC-RSC, EC-HT, TDS-RSC, TDS-HT, SAR-SSP and RSC-HT.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22201 J. Environ.

The contamination of groundwater by arsenic (As) in Bangladesh is the largest poisoning of population in history, with millions of people exposed. Thirty (30) water samples were collected from 5 different Upazilas of Manikganj district in Bangladesh to determine the concentration of As as well as to assess the level of contamination. Concentrations of As in waters were within the range of 0.27 to 1.96; 0.43 to 5.09; trace to 6.69 mg L-1 at Singair, Harirampur and Ghior Upazila, respectively. But the concentration of As in waters both of Manikganj sadar and Shivalaya Upazila were trace. All surface and groundwater samples of Singair and Harirampur, and 4 groundwater samples of Ghior Upazila’s exceeded Bangladesh standard value for As concentration (0.05 mgL-1). The highest As concentration (6.69 mgL-1) was found in groundwater of Baliakhora village of Ghior upazila in Manikganj district. The cation chemistry indicated that among 30 water samples, 15 showed dominance sequence as Mg2+ > Ca2+ > Na+ > K+ and 14 samples as Ca2+ > Mg2+ > Na+ > K+. On the other hand, the dominant anion in water samples was Cl- followed by HCO3- and SO42-. Highly significant positive correlations were found in between the concentrations of As and SO42-(r=712**),and As and Ca2+ (r=581*), suggesting similar sources and/or similar geochemical processes controlling the occurrence of these ions in waters.J.
