ABSTRACT Integrated farming systems are promising strategies for the recovery of pastures and degraded soils. This study aimed to evaluate the effect of integrated farming systems arrangements, after four years of implementation, on the fertility, carbon stock and aggregate stability of an Alfisol, in the semiarid region of the Paraíba state, Brazil. A randomized block experimental design was used, with 5 treatments and 4 replications: Brachiaria decumbens; B. decumbens + Tabebuia impetiginous; B. decumbens + Gliricidia sepium; B. decumbens + Mimosa caesalpiniifolia; and B. decumbens + maize. The soil chemical attributes, fertility, carbon stock and structural and aggregate stability were evaluated in the 0.00-0.10, 0.10-0.20 and 0.20-0.30 m layers. The B. decumbens + maize system presented an organic matter content 11.93 % higher than B. decumbens, and was higher than the other systems evaluated. Concerning the carbon stock in the 0.00-0.10 m layer, in B. decumbens the uptake was 2.66 Mg ha-1 higher than that of the B. decumbens + maize system and, on average, 4.69 Mg ha-1 higher than for the systems with the arboreal component. In the medium-term, B. decumbens is more efficient in adding carbon to the soil. The soil structural stability, aggregate stability index and fertility were not affected by the different arrangements after four years of implementation.

Abstrak: Masyarakat yang tinggal di kampung nelayan adalah masyarakat yang memiliki masalah yang kompleks. Salah satunya adalah dalam hal masalah kemandirian ekonomi. Studi ini mendeskripsikan masalah tersebut dengan pendekatan politik lingkungan. Studi ini juga mendeskripsikan tentang peluang masyarakat di kampung nelayan dalam upaya meningkatkan kemandirian ekonomi melalui pendekatan politik lingkungan. Temuan studi ini adalah terdapat empat peluang yang dapat dimanfaatkan masyarakat di kampung nelayan dalam upaya meningkatkan kemandirian ekonomi. Peluang pertama adalah menjalankan usaha tambahan dengan melakukan wirausaha ramah lingkungan. Peluang kedua adalah memaksimalkan produksi dengan sistem pertanian terpadu. Peluang ketiga, menggagas dan mewujudkan kampung ekowisata. Peluang keempat, membangun unit usaha bersama seperti koperasi berbasis lingkungan. Studi ini dilakukan dengan menggunakan pendekatan kualitatif. Data dan informasi yang ada diperoleh melalui proses wawancara, dan diskusi pendek, serta melalui penelusuran literatur melalui dokumen elektronik dan dokumen cetak.Abstract: People living in nelayan villages (kampung nelayan) have complex problems. One of them is economic autonomy. This study describes the problem with a political ecology approach. This study also describes the opportunities of people in nelayan villages in an effort to increase economic autonomy through a political ecology approach. The findings of this study are that there are four opportunities that can be utilized by communities in nelayan villages in an effort to increase economic autonomy. The first opportunity is to run an additional business by doing eco-friendly entrepreneurship. The second opportunity is to maximize production with integrated farming systems. The third opportunity is to initiate and create an ecotourism village. The fourth opportunity is to build a joint business unit such as an environment-based cooperative. This study was conducted using a qualitative approach. Data and information are obtained by interviews and biref discussions, as well as electronic document literature and printed documents.

Abstract Israel is located in the Middle East between Africa, Asia and Europe. Like many semi-arid countries, it faces a water shortage due to limited rainfall and freshwater sources. However, in spite of climatic constraints and overall shortage of water, both agriculture and aquaculture are highly developed. Different methods and solutions to maximize water use were developed to deal with the impediments of water and weather. Agriculture is largely intensive and dependent on irrigation from reservoirs during the dry summer. These irrigation reservoirs are also used for fish culture, in integrated farming systems. Large-scale recirculation systems are in use in which water from fish ponds, and/or tanks in greenhouses or outdoors, is passed through large sediment ponds and water treatment systems before returning to the culture systems. A combination of irrigation reservoirs and fishponds/tanks is also used. Other combinations of fishponds and agricultural crops are also trialed and in use.
