The research team used both quantitative and qualitative approaches in their work. Discussions were held with key stakeholders at the provincial and community levels, as well as with randomly selected households, as part of the study. The information was gathered through the use of quantitative Household Questionnaires and qualitative Key Informant Interviews. People's socioeconomic livelihoods and critical aspects such as agriculture, health, education, housing, water and sanitation, and property were found to have been negatively impacted by floods according to the findings of the study. As a result, any negative impact on livelihood would result in lower household incomes and lower purchasing power for households. In Paktia, as in many other parts of Afghanistan, there has been extensive deforestation. In recent years, devastating floods have resulted as a result of this. The following are the most important recommendations made: • Since communities have expressed a desire to relocate permanently to higher ground, the government and key stakeholders should engage them in the process of relocating permanently to higher ground. Their relocation should be accompanied by the provision of all necessary social amenities, such as schools, hospitals, infrastructure, water, and agricultural support, for a period of three (3) years to allow the households to settle in the new location. It should also be taken in the newly established settlement area. • A deliberate policy should be implemented to compel communities, particularly in rural areas, to construct houses out of durable materials and away from flood-prone areas, which would be beneficial. • Communities should be encouraged to expand the area under cultivation on upland land in order to improve food security and household income. • Both non-flooding and flood-prone areas should be clearly delineated by the appropriate authorities. During floods, the non-flooding areas can be used as a makeshift temporary shelter for the settlements. • Construction of dams should be considered as a means of capturing the surplus water. This could be used to irrigate the garden. • Consideration should be given to the construction of canals into the main Kurrama River.

These water catches are amongst the most important sources of freshwater and are increasingly used for agricultural, industrial and other purposes. Over extraction and misuse of water has faced these resources with big challenges. The use of fertilizers and manures, and the careless discharge of sewage water have affected underground water and gave root to the increasing levels of nitrates. Gardiz, which is the capital city of Paktia Province, has faced the same destiny of nitrification. The current study has been conducted to know the amount of nitrates in 12 wells and 3 karezes. Clarometer standard method for knowing nitrates amount is used. The results shows that the nitrates content to be in the range of 46.15 to 51.10ppm, which makes up to 20% percent of the total tests. The World Health Organization (WHO) classifies water containing this amount of nitrates as unsafe for drinking. 80% percent of the remaining tests have, luckily, affirmed that the content of nitrates is low, thus water from these sources can be used for drinking. Attempts; however, have to be made to stop nitrification of these resources that is mainly caused by the negligent discharge of manures and sewage water.

In addition, population growth and the effects of cyclic droughts on irrigated agriculture have put pressure on the available water resources. Such prevailing conditions have the effect of creating an imbalance between the increasing water demand and limited available water supply. Under this perspective, effective planning and management can only be obtained on the basis of reliable information on spatial and temporal patterns of farmer's water demand, on farming irrigation practices, and on physical and operational features of large-scale irrigation systems. The timely and reliable assessment and monitoring of water resources and systematic exploration and developing new ones is of paramount importance. For this, it is necessary to employ modern methods of surveying, investigations, design, and implementation. Remote sensing and GIS are viewed as an efficient tool for irrigation water management. Geographic Information System (GIS) and remote sensing techniques can provide managers and planners with the visualizing effects resulting from various management strategies, under different climatic and operational conditions. They can be used as analytical tools and can significantly enhance the ability of researchers and practitioners responsible for investigating water management alternatives.

Kesar. The experiment was evaluated in a Randomized Block Design with ten treatments and replicated thrice. Treatments involved foliar sprays of potassium silicate (1, 2 and 3 ml/l), silicic acid (2, 3 and 4 ml/l), salicylic acid (1500, 2000 and 2500 ppm) and unsprayed control. Results revealed a significant impact of treatments on all parameters included in the study. Application of silisic acid and salicylic acid recorded significantly higher number of fruits per tree, fruit weight and fruit yield in mango cv. Kesar. Trees sprayed with salicylic acid at 2000 ppm had the maximum fruit retention (89.83%), fruit weight (290.17g), fruit length (12.10 cm) and breadth (8.60 cm). However, number of fruits per panicle (1.77), number of fruits per tree (419) and fruit yield per tree (120.64 kg/tree) were highest under salicylic acid at 2500 ppm. In the current investigation, salicyclic acid at 2000 ppm proved most effective for improving fruit retention, increasing fruit yield and inducing better sized fruits.

A collaborative strategy should be adopted for increasing productivity by intensifying available land use system. Intercropping is advanced management practices of soil fertility status, consisting of cultivating two or more crops in the same space at the same time. The most common advantage of intercropping is the production of greater yield on a given piece of land by making more efficient use of available resources using a mixture of crops of different rooting ability, canopy structure, height, and nutrient requirements based on the complementary utilization of growth resources by the component crops. Moreover, intercropping improves soil fertility through nitrogen fixation from atmosphere with the use of legumes, increases soil conservation through greater ground cover than sole cropping. Also, intercropping systems are beneficial to the smallholder farmers in the low-input and/ or high-risk environment of the sub-tropic, where intercropping of sugarcane and legumes is widespread among smallholder farmers due to the ability of the legume to contribute to addressing the problem of declining levels of soil fertility. This review paper covering the role of intercropping systems in sugarcane to improve, growth, yield and nutrient status of soil under smallholder farms of semi-arid area of India and world. The intercropping systems in sugarcane are useful in terms of increasing productivity and profitability, water n use efficiency, control of weeds, pests and diseases. In this study, the work carried out by researchers about different intercropping system in sugarcane is discussed, and it would be beneficial to the researchers who are involved in this field.
