Environmental Protection Through Environmental Services Payments

To provide goods and services to human’s ecosystems need water like fish, timber, food, grains, among others. Similarly, are responsible for important services for the preservation of the quality and quantity of water available, such as the supply and maintenance of water flows and smoothing of natural disasters related to water, such as floods and droughts. This work was carried out to explain why the existence of this type of payment services in the pursuit of environmental protection exercised in several countries including environmental Brazil, based on the location of cases of payment for environmental services. Some countries have already practiced the payment for environmental services and the majority of services is related to water. Environmental service providers whose main goal that the business is profitable and remains. Payment for environmental service exists as an incentive to conserve the environment so profitable to the owner of rural land or forests ale smallholders and farmers.

Qualidade das águas cinza tratada com fitorremediação em unidades de produção agrícola

A irrigacao e uma atividade que necessita de grande quantidade de agua, o tratamento de aguas cinzas provenientes de uma lavanderia publica em regioes semiaridas para reuso passa a ser uma alternativa de sobrevivencia neste ambiente e favoravel no desenvolvimento economico sustentavel. Nesse contexto, a pesquisa foi realizada no distrito de Ribeira no municipio de Cabaceiras - PB objetivando-se avaliar a qualidade da agua cinza tratada com fitorremediacao nas unidades de producao agricola. Foram realizados dois tratamentos com(Tanque 2) e sem fitorremediacao(Tanque 1), a cultura utilizada foi o capim elefante roxo. Foram coletadas amostras mensais e analisadas os seguintes parâmetros fisicoquimicos: Turbidez, pH, Condutividade eletrica (Ce), Demanda Quimica de Oxigenio(DQO) e Fostoro Total. Para a turbidez os valores dos tratamentos foram acima de 1.000 UNT. Na demanda quimica de oxigenio, o valor minimo foi de 311mg/L (setembro) e maximo de 438mg/L (outubro) no tanque 2 em contrapartida no tanque 1 o valor minimo foi de 354mg/L (setembro) e maximo de 618mg/L (outubro). O tratamento com fitorremediacao teve uma maior eficiencia na reducao de DQO. Palavras – chave: capim elefante roxo, reuso, irrigacao

CULTIVO DE GIRASSOL EM VARIEDADES DE SUBSTRATOS

The use of solid wastes as substrates can provide components for cost reduction in the production of seedlings . In this context , the research was conducted in a greenhouse at the Federal University of Campina Grande UFCG , aiming to assess the cultivation of sunflower in different substrate compositions derived from agribusinesses . The treatments were : T1 ) Coconut Fiber ( 100 % ) ; T2 ) Coconut Fiber ( 50 % ) + sand ( 50 % ), T3 ) bagasse cane sugar ( 100 % ) and T4 ) Sand ( 100 % ) . A variety of sunflower used for the survey was 262 AG . ‘s Growth parameters were stem diameter ( DC ) , plant height ( PH) and the number of leaves (NL ) . It was found that the first review by the number of leaves, plant height and stem diameter were significant at 2.5 , 19.2 and 0.1 , respectively. The largest diameters of treatment 1 were all then reviews the T2 . In third evaluation in treatment 4 had higher values at the variables NF ALP than in T3. Coir had great results and the use of substrates from agribusiness is becoming viable sustainable production. these , the effectiveness of ME in Brazil and different scenarios that may benefit the environment.

EFEITO DO SUBSTRATO BOVINO NA GERMINAÇÃO DE PIMENTA BIQUINHO (CAPSICUM CHINENSE) IRRIGADO COM ÁGUA RESIDUÁRIA

The Brazilian semiarid region characterized by prolonged drought and poor rainfall distributed, reducing the quality and quantity of water available. In this context, the present study performed in a protected environment at the Federal University of Campina Grande aiming to analyze the germination of pepper pout with bovine substrate irrigated with different levels of wastewater treated.The treatments consisted on 5 water levels (N) using the water supply and wastewater derived from an upflow anaerobic (UASB) based on plant water requirement (NH), as follows: 100% of NH (N5) 80% of NH (N4), 60% of NH (N3), 40% of NH (N2) and 20% of NH (N1). Germination percentage (PG) the germination speed index (GSI ), mean velocity (MV) and the average time (Tm) of germination were evaluated, on biquinho pepper (BRS Moema). The germination percentage for water supply averaged 42.3% and 46.5% for wastewater. For water levels applied the average germination rate of biquinho pepper ranged from 0.086 to 0.089. The germination of pepper had better results with the use of water residuaria. O reuse of water in semi-arid regions is a viable alternative reducing costs and providing nutrients culture.

ANÁLISE DE CORPOS HÍDRICOS CONSTITUINTES DO RIACHO DAS PIABAS EM CAMPINA GRANDE/PB

Renewable natural resources are considered inexhaustible arising from to capacity for restoration after use by man , when used appropriately. In this context, this research was carried out in the catchment of the creek Piabas aiming to assess the water quality constituents of water bodies from the creek minnows for various purposes . Eight (8 ) water samples were collected in shallow natural sources such as streams , ponds and spring ; and sub - surface sources such as wells and ponds and analyzed the hydrogen potential ( pH ) , electrical conductivity (EC) , turbidity and dissolved oxygen ( DO) . The Electrical Conductivity parameter of irrigation water ( EC w ) has no degree of restriction ( < 0.70 dS m - 1 ) mild and moderate ( 0.70 to 3.00 dS m - 1 ) , with a minimum value of 0 29 dS m-1 and a maximum of 2.23 dS m- 1. Turbidity in the highest value was 1.9 and the lowest 1.3 NTU . In all samples the dissolved oxygen values are greater than 5 mg / L recommended by the MS 2914/2011.As samples can be used for animals , but there restrictions with regard for human consumption and irrigation .
